• Moreno Valley Unified Community Wellness Center Welcomed EFNEP

  The Moreno Valley Unified School District (MVUSD) wanted to create a place to eliminate learning barriers by providing students with a school-based program that promotes health, safety, and resources through community partnerships. The new Community Wellness Center was finally opened in January 2018. The District Wellness Liaison, Ms. Connie Edwards, dreamed of this day for many years. The new center now provides care and services to homeless students and youth in temporary homes, and distributes basic needs items such as clothing, shoes, and food. In addition, the Center offers classes in self-efficacy, literacy, health, and nutrition to the District’s parents. Moreno Valley has higher than average poverty rate (16.8% below poverty level as compared with 15.1% for California; factfinder.census.gov). The obesity rates are also higher (30.6% for adults and 39.7% for teens in Moreno Valley as compared with 24.8% for adults and 32.4% for teens in California; shaperivco.org).

• EFNEP Educator Made Learning Fun!

  Getting teachers to sign on to do nutrition education in the classroom is not always an easy task. Nutrition education is often viewed as an additional burden on top of mandated standards and other responsibilities that teachers already have. Although teachers are supportive and see nutrition education as valuable, sometimes they simply do not have time to prepare and implement a nutrition program. According the 2017-2018 California Physical Fitness Report, one in five students in Riverside County are obese (20.5% 5th graders, 19.0% 7th graders, 19.5% 9th graders). Therefore, it is important to instill healthy eating habits early in life.

• UC ANR 4-H bridges the higher educational gap for Latino youth

  Latino students constitute 52% of the K-12 public school population in California. In 2014-15, Latino students were less likely to graduate high school than their non-Latinos counterparts. Eleven percent of Latinos ages 25 and older have at least a bachelor’s degree, compared with 40% non-Latinos in that age group. The Pew Research Center shows that those without a post-secondary degree are more likely to be unemployed than those with, 12.2% vs. 3.8% respectively.

• UC CalFresh’s Youth Engagement Initiative builds tomorrow’s leaders

  Youth live, play, eat, shop, and learn in their communities but are rarely included in decision-making processes that directly impact their health and nutrition. Engaging and building the capabilities of youth as leaders is an important step toward effective policy, systems, and environmental (PSE) changes. Three counties in California—El Dorado, San Mateo, and Imperial—initiated pilot Youth Participatory Action Research (YPAR) projects during the 2016-2017 school year. All school sites are located in rural regions that face similar issues, such as lack of access to healthy foods, no walkability, and geographic isolation from the rest of the county. As a result, these communities have high rates of obesity, low physical activity, and poor nutrient intake.

• UC researchers discover cost-saving response to pathogens in restoration sites

  Introduced plant pathogens together with other invasive organisms represent the third most significant threat to biodiversity and the integrity of native ecosystems. To date, not a single exotic plant pathogen has ever been eradicated from natural ecosystems. The damage these introductions causes is irreversible and can be estimated in the billions of dollars annually for the US alone. Recently, a group of the most aggressive plant pathogens, Phytophthora, were discovered to be introduced through infested plant material used in restoration projects. These introductions establish the exotic microbes as they are placed in an ecosystem while thriving on a host. Rather than having successful restorations, there is a potential for failed restorations and disease progression into areas adjacent to these sites.

• UC ANR develops online tool to calculate forage loss from California rangelands fire

  Wildland fires have occurred with increasing frequency in recent years. Most of the affected land is rangeland, providing forage for livestock and wildlife. Forage production can be impacted for three years post-fire. That means that not only is there an immediate and complete loss of forage, but a 40% reduction on average the year following the fire and a 20% reduction on average the second year. Documenting forage loss is important to aid in financial recovery, whether from an insurance claim or federal funding for disaster relief.

• UC Cooperative Extension takes leading role in climate change research and extension

  Rising summer temperatures and extreme events – including a recent swing from a 5-year drought to one of the wettest winters on record – are indicative of a warmer, more variable climate future in California. The changing climate has already begun to stress our social, economic, and ecological systems. It is threatening crops, increasing catastrophic wildfires, harming fish and wildlife, and limiting water supplies while also increasing flood risk and ultimately impacting the health and quality of life for Californians. Public awareness of climate change impacts is growing, but there is significant uncertainty around how climate change will affect natural resources and communities. The University of California’s Division of Agriculture and Natural Resources (UC ANR) representation across the state and engagement with its diverse communities uniquely positions us to understand and communicate the consequences of climate change and identify strategies to mitigate negative outcomes for local economies, the environment, and public health.

• UC spurs oak woodland conservation momentum and policy changes

  The loss of deciduous oak woodlands to native conifer encroachment is a major conservation concern in California, resulting in associated losses of wildlife habitat, traditional uses, biodiversity, and other ecosystem services. These concerns – compounded by development pressures, evolving understanding of fire’s role in California landscapes, and health threats like sudden oak death – have drawn increasing attention in recent years, and conservation and restoration efforts have gained momentum. However, efforts are complicated by a paucity of information on the rate and extent of conifer encroachment, successional dynamics, and trajectories of oak regeneration and conifer recruitment in a changing climate. Landowners, policymakers, conservation groups, and agencies have looked to UCCE for scientific guidance and landowner cooperation.

• UC CalFresh Imperial County Empowering Youth as Leaders

  Childhood obesity is a problem that affects many in the Imperial County - 40.9% of 5th graders and 45% of 7th graders are overweight or obese. Fitness levels are low- only 13.9% 5th graders and 23.6% of 7th graders meet all of the fitness standards (ED-Data, 2018). Imperial County is known for its desert location with little access to indoor recreational facilities and highly accessible fast food restaurants. Empowering youth as leaders to address the issues affecting the health of their families will create change in Imperial County.

• California 4-H Youth Summit- supporting diversity and inclusion

  The California 4-H Youth Development Program has a goal to reach 3% of the youth population in the state by 2025 while reflecting the demographics of the youth population in the state (52% Latinos, 6% African American/Black, 12% Asian American and 30 % White). We want to provide all the youth in our state the same opportunities to achieve their full potential, which is a key component of our mission statement. One way for youth to achieve their full potential is through leadership development.

• EFNEP Helps California’s Low-income Families Make Healthy Choices while Saving Money

  Twenty-five percent of California adults are obese while over 30% of California children, ages 10-17, are considered overweight or obese. One in eight Californians experience difficulties providing healthy nutritious foods for their family.

• Shaping Healthy Choices Program Initiated in Riverside

  The UC Davis’ Center for Nutrition in Schools has created and research-tested the Shaping Healthy Choices Program (SHCP) since 2012. This evidence-based program is a multi-component, school-based intervention addressing the complex issue of behavior change and childhood obesity. In 2016, about 48% of teens in Riverside County were designated obese (highest 5th percentile) and 11% overweight (www.ask.chis.ucla.edu). Recognizing this issue, the UC CalFresh Nutrition Education Program in Riverside County partnered with two school districts to implement the Shaping Healthy Choices Program.

• EFNEP Brought Enrichment Activities to Summer Meals Program

  The first Out-of-School Time Nutrition Summit for Southern California hosted by California Summer Meal Coalition of the Institute for Local Government was held in Upland, CA in January 2017. This meeting highlighted the needs to support and increase summer meals participation in the Inland Empire. The Summer Meals Program is funded by USDA to ensure that youth from families that are food insecure continue to receive nutritious meals when school is out. The number of students eligible for Free/Reduced Price Meal in Riverside County is 270,907 (63% of student enrollment). During summer, Riverside County has over 200 summer meal sites providing healthy lunches, however, the summer lunch daily participation average is only 17,113 or about 6% of eligible students.

• Tackling Childhood Obesity: A Systems Change Approach

  On paper, the charge was clear: launch a statewide effort to integrate the nutrition education programs of the US Department of Agriculture’s Supplemental Nutrition Assistance Program-Education (SNAP-Ed) funded partners. Address childhood obesity and food insecurity holistically, yet specifically. Do this through policy, systems, and environmental approaches that will leverage community participation and resources in order to create sustainability at the local level. Accomplish this as funding is declining in SNAP-Ed programs. What would this integrated effort look like in practice? How could a work plan weave together the many agencies, actors, and systems that influence a child's earliest years, a family's food selection, and school and community activities?

• UC ANR introduces twelve Mexican Delegates to 4-H

  The United States and Mexico have a long story of political, economic and scientific collaboration. Since 1994, when the North American Free Trade Agreement (NAFTA) came into effect, the U.S and Mexican relationship was profoundly transformed. Twenty years after NAFTA, UC President Janet Napolitano launched the UC-Mexico initiative in recognition of the fact that many of the issues facing California also face Mexico. This initiative has allowed UC and Mexican faculty to do collaborative research on climate change, water resource management, and migration and health issues among dozens of other topics. However, little attention has been brought to Cooperative Extension projects and research. Mexico could benefit from the more than 100 years’ experience of Cooperative Extension in the U.S., and California could benefit from exchange programs that help us to better serve the Latino population in the state.

• Avocado Educational Grower Seminar Series Continues to Progress and Benefit California Growers

  California produces about 90 percent of the nation's avocado crop. California avocado growers compete in both the domestic and international markets with countries with much lower costs of production and labor availability. To stay competitive will require more efficient farming strategies and a significant increase in productivity on the part of California growers, especially with the increase of water costs and labor constraints. To adapt, growers need to dramatically increase yield per acre using the same amount of water or less. Evolving farming practices and new information is essential for growers to stay competitive with the world market.

• UC CalFresh Program Excited Student Interest at Torres Martinez Tribal TANF

  Forty percent of Coachella Valley children aged 2 to 17 are overweight or obese (2013, harcdata.org). Located in a remote area with limited access to fresh fruit and vegetables, the Torres Martinez Desert Cahuilla Indian Reservation covers 24,024 acres of desert spanning part of Coachella Valley and Imperial County, with an estimated population of 4,000. The tribal headquarters, in the unincorporated community of Thermal, is the location of the Temporary Assistance for Needy Families (TANF). TANF is charged with providing assistance and social support to families with children on the reservation. TANF Family Preservation Services, Youth Division was interested in nutrition education that would help children develop good eating habits and a healthy lifestyle.

• UC CalFresh Fresno helps transform challenge into change

  Poverty combined with high unemployment rates can be a recipe for disaster. Entire families become engulfed in crisis. Rescue the Children (Rescue), a ministry of the Fresno Rescue Mission, is a nonprofit that transforms lives lost to drug or alcohol addiction and assists homeless families and previously incarcerated women. Rescue provides an in-house rehabilitation and transition program. Priscilla Robbins oversees the program and noted the importance of including a nutrition and healthy living component.

• California 4-H Increases Reach with Latino Youth

  With 15 million Latino residents, California accounts for more than a quarter (27%) of the nation’s Latino population. Over 52% of California’s K-12 students are Latinos. California Latinos live in households with median annual income of $47,180 (the California state median is $60,883), with 20% of Latino youth living below the poverty line. These income gaps are related to opportunity gaps for youth; for example, access to high-quality youth development programs, early preparation for college, and peer and adult mentoring.

• Promoting civic engagement in California’s Latino youth

  In 2014, Latino’s became the “new majority” in the state of California, with 14.99 million representing 38.75% of the total population (Los Angeles Times, July 2015). Latinos (Hispanics) are the nation’s youngest major racial/ethnic group with an average age of 28 years old. Nearly half of U.S.-born Latinos are younger than 18 (Pew Research Center, 2016). California Latinos under age 18 now comprise 23.2% of the overall population (U.S. Census Quickfacts, 2016). Regrettably, Latinos continue to be underrepresented among voters compared to those eligible to vote and the overall population (Romero, 2016). Due to this new demographic for California and the United States, it is particularly important that Latino youth develop into engaged and informed citizens to respond to their increasing influence in the elections. Latino populations need to become more educated and more civic-minded.

• The UC ANR 4- H Latino Initiative develops a culturally responsive Career Day

  In 2016, fifty-two percent of K-12 students in California were Latinos and 35 % between 18 and 24 years old were enrolled in a two or four-year college, up from 22 % enrolled in 1993. However, only 15% of Latinos ages 25 to 29 had a bachelor’s degree or higher (Pew Hispanic Research, 2016). A 2015 report from The Campaign for College Opportunity, stated that, “among current Latino undergraduates, 65 percent attend a California community college but only 39 percent will earn a degree, a certificate, or transfer within six years — in comparison with 53 percent of whites and the statewide average of 48 percent” (Daily News, 2015). Importantly, research also shows that millennials with a college degree are less likely than those without a college degree to be unemployed, 3.8% vs. 12.2%, (Pew Research Center 2014). The UC ANR 4-H Latino Initiative, currently piloted in seven Counties, is working towards addressing the needs and building upon the strengths of Latino communities across California to foster higher education attainment through 4-H Youth Development programs.

• Improved management of Lygus bugs has reduced unnecessary insecticide applications reducing risk to crops and the environment

  The Tulare Lake Bottom is an area in Kings County, California that produces a variety of row, field and vegetable crops. Crop rotations of safflower, cotton and tomato are essential in maintaining soil quality and managing ground water issues. In the westside of Fresno and Kings Counties, major changes to cropping landscape took place in a single year. The shift to safflower overwhelmed the landscape and resulted in a breakdown of expected patterns of insect migration. In order to improve Integrated Pest Management (IPM), the management of key pests such as Lygus bugs must be considered at a larger and wider level then individual fields and farms.

• Collective impact: The Calaveras County experience

  Statistics can inform us of challenges counties face, but people create solutions. This is well illustrated in Calaveras County, a rural Sierra foothills community. Calaveras residents face many stumbling blocks to sustaining a healthy lifestyle. Dogged by high unemployment, the overall food insecurity rate is over 15%, with a rate among children as high as 23%. Other challenges include isolated residential areas with limited public transportation and infrastructure. In addition, the community has experienced natural disasters such as the 2015 Butte Fire, affecting over 12,000 people in the Sierra foothills.

• A New Vegetable Garden Increased Community Spirit

  The Eastside Neighborhood, one of the oldest residential areas of the City of Riverside, is also one of the poorest. More than half of the adults and almost a quarter of the teenagers were considered overweight in 2012 when Kaiser Permanente funded the Heal Zone Initiative to improve the community’s overall wellness through education and increased access to healthy local food. The Community Settlement Association (CSA), founded over 100 years ago to help immigrants from Mexico settle into Riverside, now provides social services and food distributions to the Eastside residents. The Association needed assistance to revitalize the existing garden to help residents have access to fresh produce.

• Alameda County’s 2017/2019 Integrated Plan, Best Written in Western Region

  Collaborations create value and accelerate change said Terry F. Yosie, president and CEO of the World Environment Center in Washington, D.C.: “Corporations, non-governmental organizations and institutions… are more successful in attaining individual objectives by collaborating with partners with aligned interests…”, (https://www.greenbiz.com/blog/2013/04/29). Alameda’s County Nutrition Action Partnership (CNAP) was first organized in 2006 with six USDA Supplemental Nutrition Assistance Program Education (SNAP-Ed) providers. University of California Cooperative Extension (UCCE) is one of the founding members. CNAP is faced with the challenge of reaching 209,000 county residents, representing 13 percent of the population that are living in poverty and eligible for SNAP-Ed. This challenge includes reaching youth in 206 schools, (52 percent of the County’s schools) and families spread across 45 of the County’s 360 census blocks.

• UC ANR 4-H builds bridges with Mexico by helping launch a 4-H Club in Mexicali

  Baja California, Mexico, and California, U.S.A. share a 156-mile long border which includes cities like Tijuana and Mexicali. Even when both states are geographically close, the disparities between them are incredibly large in terms of population, income, and education. For example, in Ejido Sinaloa, in Mexicali only 37% of the population is employed, the average monthly income per household is $450, and the average level of education is 7th grade. California and Baja California also share an agricultural legacy that has been challenged in recent years by issues such as drought and climate change, which do not recognize borders. Mexico and the US require leaders, scientists, educators, entrepreneurs, and professionals with an outstanding education to solve these issues. For more than 100 years the 4-H youth development program (4-H) in the U.S. has facilitated the development of leaders in part by increasing the number of youth that gives back to the community, make healthy decisions, and improve their grades at school.

• UC ANR teamed up to investigate effective integrated pest management for bed bugs in low-income, multiple-occupancy housing

  Bed bugs, their bites, and the associated social stigma continue to plague many Californians and draw widespread attention from the media. Although bed bugs can occur within a wide range of human habitations and income-levels, it’s those who live in low-income, multiple-occupancy housing who appear to suffer the greatest. Integrated Pest Management (IPM), first developed by UC in the 1940s for agriculture, offers a theoretical framework for bed bug management in multiple-occupancy housing

• UC IPM delivers IPM solutions to Californians

  Chlorpyrifos is an important insecticide in IPM programs for alfalfa, almond, citrus and cotton due to its efficacy, value as a resistance management tool, and established international registration status. Public health and environmental concerns about chlorpyrifos resulted in an ongoing evaluation about its use in agriculture. Regulatory safeguards could include changes in use, up to and including full cancellation of registration. Crop teams, made up of industry leaders, agreed that stewardship and education are needed to ensure the safe and effective use of chlorpyrifos. Additionally, decision support tools are needed to enable pest control advisers (PCAs) and growers to recognize when chlorpyrifos use is necessary and justified. The new generation of PCAs coming into the field provides an excellent opportunity to train emerging professionals about chlorpyrifos use.

• UC IPM coordinates a statewide conversation about the role of chlorpyrifos

  Combined, alfalfa, almond, citrus, and cotton represent a value of over $10 billion, and are grown on 2.5 million acres of farmland. Chlorpyrifos is an agricultural insecticide used in these crops as well as other food, fiber, and forage crops in California. Chlorpyrifos is an important tool against invasive pests and endemic pest outbreaks due to its efficacy, value as a resistance management tool, and established international registration status for exporting agricultural commodities. Currently, there are ongoing evaluations at the state and national levels to assess potential human and environmental health risks from chlorpyrifos and to consider what, if any, regulatory actions on chlorpyrifos might provide further safeguards up to and including full cancellation of the registration. The results of the safeguards could change the use of chlorpyrifos, including increased use restrictions and could impact many well-established IPM programs previously developed by UCCE scientists.

• UCCE Alameda Helps Change The Culture In Preschools.

  Family food security is important in the quest to increase the consumption of healthy foods. Rasmussen, et.al. 2006 literature review examined the “determinants of fruit and vegetable consumption among children and adolescents”. They reported that the key determinants of fruits and vegetable intake are gender, age, socio-economic position, food preferences, parental intake, and availability or accessibility in the home. Families with limited funds need critical life skills to help them manage their resources smartly to pay their bills and feed their families. Preschool teachers in the Hayward Unified School District (HUSD) started early trying to teach preschoolers some of the basic concepts of how to manage limited food dollars.

• EFNEP Reached Out to Home-Based Head Start Parents

  In the Inland Empire (Riverside and San Bernardino Counties), the Head Start programs serve disadvantaged families with children from birth to the age of 5 in Head Start center or home-based options. In the home-based program, a Head Start teacher visits with parents in their home weekly to teach them strategies to enhance child development, and improve health and school readiness. It is estimated that about 14.5% of children under five are overweight for their age in the Inland Empire. Head Start teachers understand that parent involvement and education is a key to helping children start on the right path to good health and seek assistance to bring nutrition education to the Head Start parents. UC Cooperative Extension Expanded Food and Nutrition Education Program (EFNEP) has long provided nutrition classes at the center-based locations, but the home-based Head Start parents were left out.

• UCCE Riverside helped Alvord Unified get recognition

  Alvord Unified School District was awarded a $1.1 million Physical Education (PE) Program Grant for 2012-2015 and UC Cooperative Extension was a partner on this grant. In addition to improving PE programs, the grant objectives include increasing ongoing assessment and monitoring, increasing district and community support, and transitioning from a sports-based PE program to a wellness-based curriculum aligned to State standards. To be successful, Alvord Unified needed a team of dedicated partners. UC Cooperative Extension was one of the key partners working alongside others such as the Alliance for a Healthier Generation funded by Kaiser Permanente Thriving Schools, the Nutrition Education Obesity Prevention Program, and 15 other public entities and community-based organizations.

• Wellness Challenge leads to results at the 4-H State Leadership Conference

  National and state priorities highlight the importance of modeling and encouraging the best health and safety habits when working with children to support optimal development and success. Currently, several steps are being taken to strengthen the physical, social, and emotional health for all 4-H participants. 4-H events are ripe for strengthening, such as, by improving the nutritional value of snacks and beverages, increasing the amount of sleep scheduled, and eliminating some “hazing” traditions that may undermine emotional safety. The Wellness Challenge, conducted in 2015 and 2016 at the State Leadership Conference (SLC), is one way to identify and address how to best support 4-H event planning and execution in the future.

• Playing for Life: Integrating Physical Activity into Preschool Programs

  Starting early with creating a lifetime habit of play and movement is critical. Research links overweight/obesity, poor nutrition, and lack of physical activity to negative physical, academic, social, and psychological outcomes. While a constellation of factors contributes to weight gain in children and adults, one factor—inactivity—can be addressed through the integration of physical activity (PA) into daily schedules. "Easier said than done" is a comment frequently made. However, USDA-funded Supplemental Nutrition Assistance Program Education (SNAP-Ed) agencies are now engaged in strategies to integrate PA into their nutrition programs. This is part of recognizing that direct nutrition education, coupled with policy, systems, and environmental supports such as physical activity with hardscape reinforcements, help create a healthy lifestyle. Further, best practices advise that preschoolers receive at least 2 hours of both structured and unstructured physical activity daily to encourage competence in fundamental motor skills.

• Get Fresh intervention in Riverside County reaches 9,000 low-income individuals

  In Riverside County, the CalFresh program (federally known as the Supplemental Nutrition Assistance Program or SNAP) serves 289,188 low-income individuals. According to California Food Policy Advocates, 37% of low-income households in 2014 were food insecure, having limited or uncertain access to adequate food. Educating CalFresh participants about making healthy food choices and shopping on a limited budget can help to improve their nutrition and food security; however, the challenge is that this population is very hard to reach and may be at different stages of readiness to change behaviors.

• UC CalFresh – UCCE Alameda County revitalizes preschool gardens in Oakland

  Servings of fruits and vegetables consumed per day among all ages are below the Dietary Recommendations for Americans. Research shows that nutrition and gardening experiences, linked to academic standards for a specific age group, can increase vegetable and fruit consumption and physical activity. Gardening activities can help increase children's interest in eating fresh fruits and vegetables and improve their understanding of the health benefits and major nutrients found in the plants grown.

• UCCE Alameda helps develop preschool obesity prevention policies

  The early years of life are critical times in the physical and mental growth and development of the young child. Children are often exposed to many unhealthy choices at an early age while they are forming lifestyle habits (involving eating and physical activity, for instance) that may last a lifetime. Head Start and state pre-K child developments centers in Alameda County serving over 12,000 children are not affiliated with schools with federal mandates requiring nutrition and wellness policies. The Alameda County 2014 SNAP-Ed Profile shows that 33.4% of 2-to-4-year-olds are overweight/obese and 17.4% are obese. The alarming rates of obesity and the associated high risk of negative consequences establish the research basis for Policy, Systems, Environment (PSE) work—focusing on nutrition and physical activity—in early childhood (EC) development sites in Alameda County.

• UC CalFresh Yuba County: Making lunchrooms smarter

  For many parents, an ongoing battle with their child is about healthy eating practices. With more than one-third of U.S. children overweight or obese, promoting healthy eating behaviors has never been more essential. Out of this national crisis, The Smarter Lunchroom Movement (SLM) was born, spearheaded by Cornell University's Center for Behavioral Economics in Child Nutrition Programs in 2009. Their evidenced-based approach helps nudge students to make healthier choices through low cost/no cost solutions; a lunchroom environment focus; promoting healthful eating behaviors; and using policy, systems, and environmental approaches to promote sustainability.

• Partnering for Positive Health Outcomes in Shasta

  Recent studies indicate that obesity is a complex issue, with individual behavioral and environmental factors at its core. The problem can also be multigenerational, entrenched in family food choices passed from adult to child. Some experts believe that one of the most effective ways to address the obesity issue is through community-based nutrition education with "farm-to-fork" initiatives.

• Cooperative Extension, California Citrus Research Board joint seminars for citrus growers

  California is the largest producer of fresh market citrus in the United States. Growers currently face many challenges, including Huanglongbing (HLB), a bacterial disease spread by the Asian citrus psyllid (ACP). Prevention and treatment efforts are focused on ACP since there is no known cure for HLB, which has already decimated 50% of citrus crops in Florida. Furthermore, growers need to be aware of and fully understand California’s new and constantly changing laws and regulations so they can ensure that they are in compliance. California’s multi-year drought has also prompted growers to re-evaluate management strategies.

• UC partners with industry in Beef Quality Assurance

  Identification and control of preharvest critical control points for the safety of beef are necessary. In particular, the beef industry wants to eliminate residues and contamination in market beef and dairy beef products; enhance food safety and microorganism biosecurity at the beef production level, including prevention of zoonotic diseases; and improve medical care, including appropriate drug and antibiotic use, and avoid development of antibiotic resistance.

• Enhanced irrigation and crop management technologies developed in Five Points, Calif.

  The need to produce more food, feed, fiber, and fuel with less water now looms as perhaps the greatest challenge ever faced by farmers worldwide. Our ability to meet this challenge may well determine not only our overall quality of life, but also our very survival in the future. Developing and adopting enhanced irrigation and crop management technologies that achieve greater water-use efficiencies is essential.

• Bringing integrated pest management to schools

  Since the enactment of the Healthy Schools Act (HSA) in 2001, both UC Cooperative Extension (UCCE) and the California Department of Pesticide Regulation (DPR) have been working with school districts in California to provide information about integrated pest management (IPM). The strategies employed in an IPM program include modifying horticultural practices, such as changing mowing heights and managing irrigation appropriately. These practices can reduce the amount of pesticides used on school grounds to help schools to meet the standards of the HSA and provide a safe and healthy environment for students, teachers and staff. DPR has coordinated numerous workshops for school districts covering general landscape and building IPM topics. However, attendees requested more detailed training about turf IPM since they manage turf areas like playgrounds and sports fields. UCCE has extensive experience in this area and was called upon to help schools implement this policy.

• 4-H youth practice healthy living

  Obesity among 6- to 11-year-old youth has tripled over the past 30 years. Many youth and adults lack basic meal planning and food preparation skills. In a typical week in 2007, the number of dinners that were cooked and eaten at home was 4.8, but only 57 percent were prepared from scratch (Food Technology, 2008). Empowering youth and their families to adopt healthy food habits - such as planning, preparing and sharing meals at home - will improve the well-being of the entire household.

• Money Talks: Program improves financial literacy of teens

  Teenagers' financial illiteracy is a current and growing national family economic trend and concern in the United States. Teens have access to and spend a great deal of money each year. A survey conducted by Teenage Research Unlimited indicates that today’s teens spend $179 billion annually (2006). In addition to personal spending, many teens purchase food and other items to be used by the entire family. The concern about teen financial illiteracy is supported by a national money management test of high school seniors that revealed an average score of 48.3%, a failing grade by standard grading systems (Jump$tart Coalition, 2008). High school seniors have little knowledge of money management, savings, investments, income and spending. The vast majority of students aged 16 to 22 have never taken a class in personal finance, with two-thirds admitting that they could benefit from more lessons on money management. Alarmingly, 9% were rolling over credit card debit each month (ASEC, 1999).

• Biological control microorganisms for use against invasive annual grasses

  Invasive plants are detrimental to natural ecosystem services and they reduce biodiversity. Red brome and medusahead are two abundant grass species that are much more invasive here in California than in their Mediterranean countries of origin. This is likely because they left behind their natural enemies, such as root and shoot pathogens, when they left their native habitat. UCCE researchers are trying to understand the effect of above- and below-ground changes in an effort to find a way to control these invasive grasses. Managers and owners of lands affected by the two highly invasive species will benefit from this research.

• UCCE solutions for invasive pest problem on popular landscape plant

  Myoporum plants, which are native to Australia and New Zealand, include several popular ground cover and tree species that are widely planted in California for erosion control and because of their aesthetic beauty, minimal management needs, and low water requirement. Until relatively recently, California plantings have not been bothered by any insect pests. Since 2005, however, an exotic thrips species new to the United States has caused great damage to Myoporum in landscape plantings and nursery stock throughout the coastal counties of California. Thrips damage to Myoporum is characterized by gall-like symptoms and distortion of new leaves. Terminal growth can be severely stunted and leaf curling or folding, with thrips populations present within the folds, is common and eventually leads to the death of the plant. Thrips populations in infested areas have grown to extremely high levels and large landscape plantings have been severely impacted. Until UCCE got involved, there was no scientific, research-based information available on the pest.

• Ornamental plant producers acquire new markets

  Ornamental plant producers that want to increase trade with Central and South America face many challenges, including the need to develop pest risk assessments (PRAs) for their products. PRAs can be rather complicated, and the PRA process involves numerous reviews by the USDA Animal Plant Health Inspection Service (APHIS). Additionally, PRAs are sometimes deemed unacceptable by the receiving country, due to the high level of expertise in pest management required to meet the requirements of the document. The PRA can thus present a hurdle, delaying trade and, hence, potential profitability for aspiring growers and exporters. Part of the UCCE mission is to assist California growers with sustainability and profitability, and we are also the experts when it comes to pest management and pest risk. The following case set useful precedents for trade in ornamental plants with Guatemala.

• 4-H’ers drink water first for thirst!

  Childhood obesity is a major concern for University of California scientists, for families, and for the affected individuals themselves. Children who are overweight have an increased risk of developing diabetes, which has a lasting impact on the quality of life for those affected. Research shows that increased consumption of sugar-sweetened beverages is one of the most significant contributing factors to the growing epidemic of childhood obesity. By aligning with the national Drink Up campaign and making water the primary beverage for youth to drink, we can help create healthier families and communities. In addition, a major goal of the 4-H Program is to promote healthy living. “Health” is one of our 4 “H”s. The health and safety of members is a priority at all 4-H activities and events. Drinking water is crucial for good health: among other things, it helps prevent dehydration and heat illness and provides a healthy beverage alternative for those already struggling with diabetes or food allergies. Having drinking water available at all 4-H activities ensures that all members have a healthy beverage choice. The environment in which youth work and play is a key contributor to the development of their perceptions, attitudes and habits. The 4-H drinking water policy is consistent with existing obesity research and the UC Nutrition Policy Institute’s recommendation to add drinking water to the USDA MyPlate guidelines.

• Specialty coffee production is a new crop alternative in mild-winter areas of California

  Farm operators in California are often faced with limited market alternatives for traditional fruit and vegetable crops because of chronic oversupply and low prices. The development of promising new crops is one way to expand the range of options available to California farmers who want to increase the diversity of crops they grow and improve farm profitability. Specialty coffee production and marketing is a new crop enterprise alternative for frost-free areas of central and southern California. Coffee is being successfully produced, both in open-field solid plantings and as an intercrop within established avocado orchards. Coffee from California farms has now been successfully produced, processed, and commercially marketed over five successive seasons.

• Educating parents helps kids lose weight

  In the U.S., 32 percent of children are overweight or obese. Intervention and prevention efforts point to the importance of multifaceted approaches that include both children and parents. Recent research establishes important links between warm and responsive parenting practices and children’s healthy diets and weight. With children spending much of their day at school, many current interventions for obesity prevention focus on the school environment. In such cases, it is important to establish links to parents and to address the parenting environment.

• Shaping Healthy Choices Program improves children's health

  Simply offering healthy options is not enough to motivate children to make healthy choices. Moreover, imposing restrictions rather than providing children with options to make healthy choices has long-term negative implications. With recent estimates of childhood obesity showing that approximately 32 percent of children are overweight or obese, it is clear a program that addresses multiple, obesity-related factors is necessary to successfully target this complex issue.

• 4-H youth improve their technological literacy by producing films

  Youth in the United States spend much of their time with digital technologies. However, the mere use of technological devices is not enough to succeed in today's world; young people need to learn to apply and adapt technological processes and tools. Fluency with technology will help them thrive and participate in issues affecting their communities. In order to do this, they need practical, hands-on experience.

• State 4-H event promotes personal responsibility

  Young people want to contribute to their communities and are often our most enthusiastic champions. To become agents of change, however, they need opportunities to exercise and develop personal responsibility and character skills. Research shows that the development of personal character (being an accountable, committed and effective communicator) underlies individual and community success.

• UCCE equips Californians to stretch their food budgets

  During the past four years an estimated 3.8 million California adults could not afford to put sufficient food on the table. California is one of the states hit hardest by the economic downturn; unemployment rates increased from 5.3 percent in 2007 to 11.3 percent in 2009. Adjusted median household income decreased by nearly 5 percent (2009- 2010) and the poverty rate (2007- 2009) rose faster than the national level. In addition, participation in CalFresh (formerly Food Stamps) increased 6.8 percent from 2011 to 2012, significantly higher than the national increase of 2.9 percent. Add to this rising food costs of 4 percent (in 2011) and the results translate to significant increases in food insecurity, which is defined as not having enough food to ensure a balanced diet. Food insecure households are at greater risk for physical and mental health problems, such as depression, obesity, diabetes and hypertension. Although many of these families receive supplemental food assistance monies, they lack the skills to put their food budgets to maximum use.

• UCCE helps low-income Californians increase food security

  From 2007 to 2009, during the nation’s economic downturn, food insecurity in California’s low-income adult population increased from 35 percent to 40 percent. These adults were not able to procure sufficient food to maintain a healthy diet for themselves and other household members. Food insecurity effects academic achievement, increases the risk of obesity and chronic disease and impairs mental health. A 2012 UCLA Health Policy Brief reported that 38 million low-income adults in California were food insecure and that rates were highest in low-income Spanish-speaking households and those with children. Although participation in federal food assistance programs has increased since 2007, many recipients experience food resource management challenges, lacking skills to maximize their food dollars to buy, prepare and store healthy foods. Providing low-income families with food education along with resource management skills can help improve the overall health and food security of the household.

• Alameda County’s bilingual nutrition educator models effective adult education

  Alameda County is one of the most diverse counties in California, with over 30 languages spoken among 111,000 households on public assistance. Over 156,000 county residents live in poverty, and at least 25 percent are children at risk of food insecurity, poor nutrition and obesity. The largest ethnic minority groups are Hispanics, African Americans and Asian/Pacific Islanders. The number of low-income, Spanish-speaking families attending health education programs is on the rise. The county’s need for nutrition educators who are culture-, literacy-, and language-sensitive is even more evident today than 43 years ago when the Expanded Food and Nutrition Education Program (EFNEP) was piloted at UCCE Alameda in 1988–1989. Low graduation rates, however, have been a problem.

• Promoting positive youth development: Initial results from 4-H Thrive!

  Far too many youth currently fail to reach their full potential. For example, one out of five adolescents in California are at risk for depression; national costs for treating youth with mental health issues is estimated to be $12 billion. Strategies are needed to promote attributes in youth that lead to successful adult development and prevent these negative outcomes. To address this issue, the UC ANR 4-H Youth Development Program (YDP) partnered with the Thrive Foundation for Youth to deliver a new program for increasing the number of thriving youth in California who reach their full potential and become successful, contributing members of their communities.

• Surface residues and no-tillage reduce soil water evaporation

  Improving water use efficiency is increasingly important as California agriculture confronts water shortages. Changing tillage and crop residue practices could help. In regions of the world where no-tillage systems are common -– such as Brazil, Argentina, Paraguay, Canada, Western Australia, the Dakotas, and Nebraska -– generating and preserving residues are an indispensable part of management and sustainable production. Residues reduce erosion, provide carbon and nitrogen to soil organisms, and reduce soil water evaporation, along with other advantages and drawbacks. The water conservation value of crop residues and conservation tillage has not been evaluated in the warm, Mediterranean climate of California. This study measured the effects of residues and no-tillage on soil water evaporation in California conditions.

• Putting youth on the map

  A key step in fostering healthy families and communities is presenting accurate, compelling and actionable community-scale data about the condition of youth. California wants and needs for its youth to thrive — not merely to survive or face fewer problems. But how do we know whether our young people are doing well?

• Thousand cankers disease attacks commercial walnut in California

  A new disease affecting walnut trees, "thousand cankers disease," poses an environmental threat to natural ecosystems containing native black walnut species and an economic threat to commercial English walnut growers in California. If introduced to the Midwest, it may also affect commercial production of black walnut. Thousand cankers disease was first associated with widespread mortality of black walnut in Colorado, but is now known to occur in nine western and three eastern states. The disease is caused by a fungal pathogen transmitted by the walnut twig beetle, which carries spores on its back as it bores into the tree. Because numerous beetles attack a single tree, the pathogen is introduced at the many points of beetle entry. Consequently, many cankers form as the fungus colonizes and kills plant tissue.

• 4-H Revolution of Responsibility raises funds for community youth projects

  2013 marks the centennial for 4-H in California, an important milestone for an organization that is deeply connected to communities throughout the state. Service learning has been a cornerstone of the 4-H educational approach for the past century, connecting education and community service to strengthen learning and positive youth development. To celebrate the centennial, funds are being raised for youth to design and lead community-based projects. Through these projects, youth mature and develop skills while making a difference in their communities.

• Agritourism workshops build new networks for diversification

  Many factors - such as supply chain consolidation, falling wholesale prices, rising costs and economies of scale - push small- and mid-scale farmers increasingly to direct marketing and alternative enterprises to keep their agricultural businesses viable. Public demand is increasing for local agricultural products and education about local farms and ranches. Agritourism welcomes visitors to a working farm for education and enjoyment while providing additional income for the agritourism operator. In a 2009 survey by UC researchers, operators reported agritourism as a profitable diversification strategy. Agritourism requires farmers and ranchers to learn new hospitality skills and marketing partnerships, and it is a business that is regulated by zoning ordinances and permitting in each of the state’s 58 counties.

• Educating California’s youth on water issues

  Clean water is critical for life and needs to be managed wisely to ensure adequate supplies for natural ecosystems and human use. Thus, water quality and conservation are important public policy issues. In order to make informed decisions to address these challenges, citizens in today’s society require a fundamental understanding of science. Unfortunately, standardized assessments have revealed low levels of science literacy among K-12 youth in California, which also raises concerns about the future of the state’s workforce and economic prosperity.

• Adolescents Eat Better When Setting Guided Goals

  Adolescents are less physically active and eat more calories than past generations. They spend about 7.6 hours each day using electronic media, and only 1.75 hours being physically active. Intakes of calcium, iron, and fruit and vegetable intakes are low while added fats and sugars, especially in soda, are high. These eating and activity behaviors have resulted in increased obesity rates for adolescents. Today 34 percent are overweight and 18 percent are obese. Adolescent obesity increases the risk for type 2 diabetes, cardiovascular disease and cancer, and impacts school performance.

• Reduce pollution with proper fertilizer timing

  Applying nitrogen and phosphorus with irrigation water is a common practice in the Imperial Valley. If the fertilizers are applied incorrectly, the nutrients end up in the drains rather than in the crop. Nitrogen and phosphorus are the two main nutrients that cause eutrophic conditions (high algal biomass and low dissolved oxygen concentrations that cause massive fish kills) in the Salton Sea. Current and proposed federal water quality standards for California require growers to improve the quality of drainage waters. To achieve both federal and state water quality objectives, growers will have to reduce the amount of phosphorus that reaches the drains and the Salton Sea.

• 4-H develops Junk Drawer Robotics to teach youth science and engineering

  The prosperity of the United States relies upon our investment in educating and preparing future scientists and innovators to provide solutions to vexing environmental, economic, and social problems. Science, engineering, and technology rely upon one another and all have a vital role in ensuring the prosperity of our nation. However, engineering programs are still rare within K-12 school walls and in out-of-school time programs.

• UCCE explores the Farm-to-WIC Program

  Despite the documented health benefits of increasing fruit and vegetable consumption, less than 50 percent of California children eat five or more servings of fruit/vegetables daily. Low-income populations in particular face many barriers to consuming fruit and vegetables. To overcome these barriers, the federal Special Supplemental Nutrition Program for Women, Infants and Children (WIC) changed its policy in October 2009 and began distributing cash vouchers to low-income women and children to purchase fruit and vegetables.

• Citrus variety collection Is a treasurehouse of diversity

  The citrus industry in California is worth $1.3 billion, making it one of the top 10 of California crops. Oranges, lemons, mandarins and grapefruit are each among the top 33% of California export crops. To sustain this level of productivity, citrus breeders, researchers and the citrus industry need access to collections of citrus genetic resources.

• Strategies to Engage Parents in Public Decisions

  Busy parents often lack the skills or inclination to participate in public decision-making processes. Yet their insights help insure that programs for children and youth are effective. Public officials can use a variety of civic engagement tools to engage parents, including advisory committees, outreach workers, community conversations, mini-grants, or program design workgroups. But the strengths and limits of these strategies, especially in engaging low-income parents or others who are not usually engaged in public deliberation, are not clear.

• Factors and Practices that Influence Livestock Distribution

  Reducing livestock impacts on water quality, aquatic and riparian habitat, and biodiversity are continuing goals for livestock producers, natural resource managers, and conservation groups. These livestock impacts are frequently due to problems with livestock distribution. While fences are usually an effective tool for controlling livestock distribution and reducing impacts on riparian zones or other critical areas, manipulation of grazing patterns can also effectively reduce adverse impacts from livestock. These practices can also facilitate the use of grazing to manipulate vegetation to meet management goals. It is crucial that livestock producers, land managers, community watershed groups, environmental interest groups and policy makers understand the factors that influence where animals graze, rest, and drink, and how livestock can be predictably and effectively redistributed so that they do not produce undesirable effects in grazed watersheds.

• Engaging Youth as Partners in Research on Workforce Issues

  A statewide team of 4-H Youth Development advisors and UC Davis researchers enlisted youth to interview their peers as part of a study on youth workforce development programs. At issue is how to connect youth to jobs in the emerging economy, especially given evidence of rising numbers of youth who are out of school and out of work. The research sought to incorporate the perspectives of youth participants in local workforce development programs funded by the federal Workforce Investment Act (WIA). Participants were asked about their experience in WIA-funded programs, their career and educational goals, and on where they get information related to vocational and career planning.

• Evaluation finds California workforce programs succeeding but underfunded

  Since 2000, California and its partners in local workforce areas have implemented new provisions contained in the federal Workforce Investment Act (WIA). WIA gives local areas considerable discretion to tailor programs to community needs, but little was known about how this discretion was being used.

• First statewide agritourism survey: Visitors generate critical income for California small farms

  Agritourism is a vital strategy for diversifying and boosting profit for a small but significant number of California farms, but data of agritourism's economic impact as a farm diversification strategy was lacking. Agritourism is defined as any income-generating activity conducted on a working farm or ranch for the enjoyment and education of visitors. This includes on-farm produce stands, pumpkin patches, corn mazes, U-pick operations and special events such as weddings and conferences, as well as overnight stays, cooking classes, festivals, tours and lectures.

• Academy improves capacity of 13 western states to deliver 4-H science education

  Scientific literacy is necessary for developing an informed citizenry, workforce preparedness, and economic growth. However, national and international assessments of K-12 youth have revealed that U.S students' achievement scores in science have been stagnant for over a decade. Also, fewer students are pursuing science-based degrees and careers, which adversely affects the nation’s workforce. Research has documented that nonformal science programs can interest youths in science, positively influence their academic achievement and expose them to future career options in scientific fields. As one of the nation’s leading nonformal youth education organizations, the 4-H Youth Development Program can play an important role in improving youth science literacy. Furthermore, strengthening 4-H science programming can lead to higher quality educational experiences for 4-H youth.

• Biological frost control strategies reduce crop damage

  Frost damage persistently limits the production of many important crops and costs California agriculture up to $1 billion annually. Flowers of deciduous fruit and nut trees, vegetables and subtropical crops are damaged when temperatures drop even slightly below freezing. Existing methods of frost protection, such as overhead sprinklers, heaters, and wind machines, are expensive to use, limited by water supplies and relatively ineffective. For many crops, no methods of frost control are currently available or practical.

• Head Start children “Go, Glow and Grow” in Riverside

  California is one of the states with the highest prevalence of obesity among preschool-aged children from low-income families. The Center for Disease Control examined the 2009 data from Pediatric Nutrition Surveillance System and found that more than 15 percent of low-income 2- to 4-year-old children in California are overweight or obese (defined as being at or above the 95th percentile on the growth chart). In Riverside County, 13.8 percent of children ages 2 to 4 living in a household under 185 percent federal poverty level are overweight (2007 California Health Interview Survey).

• Practical method for measuring vineyard crop coefficients improves irrigation management

  The irrigation crop coefficient relates vine water requirements to climatic conditions. Having an accurate crop coefficient allows farmers to estimate irrigation requirements accurately based on local weather data. Past UC research has demonstrated that the crop coefficient itself can be estimated based on measurements of the ground area shaded by the vineyard leaf canopy at midday. However, previous methods for measuring the shaded area were not practical for commercial use, limiting the use of important irrigation information.

• Food Industry Referral Guides help California food processors and producers

  Small and large food processors, and entrepreneurs thinking about producing a food product, need similar information and services. Fruit and vegetable products specialist Diane Barrett saw the value in consolidating and centralizing information for processors and producers.

• UC 'Organically Grown' Help

  With the U.S. market for organic products expected to top $20 billion in 2006 and national organic standards in place, many farmers and consumers are looking for clarification on what constitutes “organic” and how to grow it. ANR is responding to these questions through local research and extension programs, publications and online resources.

• Oak woodland management, research and outreach

  For more than 25 years, the University of California has collaborated with the California Department of Fish and Game, CalFire and other agencies to conduct research and outreach focused on conserving California’s native oaks. In order to continue these efforts, UC has organized the Oak Woodland Conservation Workgroup (OWCW), which seeks to maintain, and where possible, increase acreage of California's hardwood range resources to provide wildlife habitat, recreational opportunities, wood and livestock, high quality water supply, and aesthetic value.

• UCCE helps bromeliad growers comply with regulations

  Ethylene, a gas found in nature and commonly used to ripen bananas and other fruit, can uniformly induce synchronous flowering in bromeliads. Synchronous flowering is key to marketing bromeliads. However, the EPA considers the gas a pesticide when used in this manner, and there are no registered uses of ethylene as a pesticide. Growers were unaware of that fact, but were told by county regulators they would have to stop using ethylene gas until it was registered. This would have caused a severe economic impact on some of the largest bromeliad growers. Synthetic chemicals are registered to induce flowering in bromeliads, but they are toxic, can cause phytotoxicity and cause asynchronous flowering.

• New invasions of eye gnats in Southern California

  The community of Jacumba in San Diego County was afflicted with an enormous population of eye gnats -- small flies that hover around eyes, ears and nose. In large numbers, eye gnats can be exceptionally bothersome. Outdoor activity in the mornings and evenings became impossible. Eye gnats are a native inhabitant of the desert southwest and San Joaquin Valley of California, but with the introduction of modern farming practices and irrigation, eye gnat populations have exploded in some areas near farm fields. Control methods have been ongoing since the early 1950s, most notably in Riverside County's Coachella Valley. In 2008, the residents of Jacumba blamed the local 400-acre organic farm for a high population of the troublesome gnats and complained to county officials. There was no avenue for action by the county, and the interaction among the county, the farmer and the community turned acrimonious. This serious urban/agriculture interface issue threatened organic food production in the area and the residents' quality of life.

• Creating a management system for spotted wing drosophila in caneberries and strawberries

  In September of 2008, UCCE in Santa Cruz County discovered a new vinegar fly pest infesting caneberries and strawberries, which was later described by the California Department of Food and Agriculture as Drosophila suzukii, and given the common name spotted wing drosophila. In 2009, spotted wing drosophila spread to cherries, blueberries, caneberries and strawberries in California, Oregon, Washington, British Columbia and Florida.

• Business planning helps small farms in a challenging economy

  Small-scale foothill farmers and ranchers are known for the quality of their products. However, excellent animal or crop production skills, hard work and dedication may not be sufficient to maintain an economically viable farm business. No matter how good their product, farmers and ranchers who lack the business and marketing skills critical to a viable small business may not be successful.

• Training offered in after-school delivery of science, engineering and technology

  The need for after-school professional development in California is great, with over 4,000 state and federally funded after-school programs and nearly that many other community-based after-school sites. Over 2 million youth, 19 percent of California’s total youth population, regularly attend these after-school programs. Even in the highest quality programs, the annual staff turnover rate exceeds 33 percent, severely impacting program quality and pointing to the need for continuous in-service training. Increasingly, after-school programs are being called upon to ramp up their science, engineering, and technology (SET) program offerings to address the decline in youth interest, competency and performance in these fields.

• California 4-H Technology Leadership Team

  Young people today consume a vast amount of media delivered by hi-tech computer technology. Over two-thirds of youth own a cell phone while 84 percent of youth have Internet access at home. However, the mere use of technological devices will not fully prepare our young people for the future. Youth need a basic level of technological literacy to make decisions, engage in civic debates, and be successful in the workplace.

• New youth evaluation tool saves teachers’ time

  A valid evaluation tool is important in education programs designed to change behaviors, skills and/or self-efficacy. Most programs use a traditional prospective pre/posttest method of data collection. A pretest is given before the start of the program and a posttest using the same questions is given after the program. This method has limitations in real-world application, especially with adolescents. Establishing rapport with youth at the first educational meeting is important for learning. Test taking at the start of the program may seem intrusive and be an obstacle to establishing trust. Youth may also rate themselves differently on the posttest, after acquiring new information during the lessons that was related to the test question. For example, youth may believe they eat enough fruits and vegetables until they learn the daily recommendations. When the posttest is completed, their responses may appear that they did not change behavior. Such miscalculation may mask actual behavior and skill changes resulting from the nutrition program.

• Eatfit: shaping the lives of adolescents

  An entire generation of California youth faces a lifetime of obesity, due, in part, to poor dietary choices and physical inactivity. Obesity reduces an adolescent’s quality of life, and can lead to life-shortening chronic health conditions such as hypertension, diabetes, heart disease and some cancers. Middle-school teachers asked Cooperative Extension educators for educational tools to assist students with healthier eating and becoming more physically active.

• Urban runoff study motivates change in landscape practices

  Recent droughts and expanding urban populations place increasing pressure on California’s water supplies. In residential areas, outdoor water use, primarily for landscapes, comprises 50 percent or more of total water use. It is commonplace to see excess water gushing down storm drains from poorly aimed sprinklers, broken sprinkler heads, and a larger volume of water applied than the soil can absorb. The runoff water can carry pesticides, fertilizers and other waste into waterways, causing a detrimental effect on the health of the aquatic life in rivers, lakes and bays.

• UCCE Shasta helps consumers grow their own strawberries

  A low cost route to improved nutrition is to grow your own food. Shasta County is headquarters to the largest strawberry nursery plant production system in California and the world. But few of the billion strawberry nursery plants produced in the county annually make it to backyards for production of fruit for personal consumption. Most nursery plants are shipped from Shasta County to coastal areas of California where fruit is grown, then shipped back to Shasta County's approximately 50 grocery stores to provide most of the strawberries for the county's 183,000 residents. Although, there is some roadside production of fresh strawberries in the spring in Shasta County, there is almost no backyard production. In fact, it is difficult to find small lots of nursery plants to grow the new flavorful and popular UC strawberry variety Albion in Shasta County.

• Seafood Safety Information Centered at University of California

  Since the April 20, 2010, Deepwater Horizon/BP oil spill, attention has focused on the safety of seafood from the Gulf of Mexico. Many fish are at risk: blue crabs, crawfish, oysters, shrimp and fish (about 86 species including albacore, channel catfish, red snapper and tilapia). The impact on the nation’s seafood industry and consumer confidence could be devastating. In a June 2010 telephone survey of 1,076 consumers conducted by University of Minnesota’s Food Industry Center, Louisiana State University AgCenter and the National Center for Food Protection and Defense, 54% of respondents said the oil spill has affected their seafood consumption somewhat, 44% said they will not eat Gulf seafood, and 31% said they will eat less seafood regardless of its origin. Further, 89% said they are concerned about the spill’s effects on Gulf seafood, while 50% are “extremely concerned.”

• Parrots as pets and the revolution in the conduct of aviculture

  In the 1970s and 1980s, the popularity of parrots as pets increased markedly in the U.S. During that time, production of parrots in captivity was limited due to a lack of information about their nutrition and reproduction. Birds, mostly parrots, became the third most popular pet after cats and dogs. Most of the parrots sold as pets, except for budgerigars and cockatiels, were caught from the wild. Capture from the wild was so extreme that it led to the endangerment of many parrot species. As a result, the Wild Bird Conservation Act was enacted in 1992 to reduce capture from the wild by stopping importation of birds into the U.S., a major market for such birds. The act has been highly effective. Since 1992, the demand for pet parrots has been met by increased domestic production. To meet domestic demand, the conduct of aviculture has improved dramatically.

• UC and IR-4 support California's fresh produce

  Most fruits, vegetables, nuts, herbs and spices that help make a healthy and diverse diet are specialty crops. To provide consumers with this wide array of fresh produce, growers of specialty crops need sustainable and affordable pest management technologies. The cost to register pesticides for each specialty crop far exceeds the purchases made by growers, who are a relatively minor segment of a pesticide company’s customers. So the U.S. Department of Agriculture created the Interregional Research Project No. 4 (IR-4) to enable the registration of low risk, effective pest management solutions for domestic, low-acreage specialty crops. No other public organization does this work so California’s $20 billion fresh produce industry depends on the publicly funded IR-4 project.

• UC creates nutrition education videos to reach diverse, low-literacy communities

  Successful promotion of healthy eating behaviors and an active lifestyle is important for the health and well-being of everyone, including low-income families from diverse backgrounds. This is especially critical for minority communities, who are increasingly at risk for obesity, being overweight, and chronic diseases like diabetes, heart disease, and cancer due to a host of social, cultural, and environmental factors. Critical barriers to nutrition education include cultural and linguistic challenges such as the lack of culturally appropriate information and materials, diverse levels of acculturation and health literacy, and limited English proficiency. Studies show that visual materials and bilingual videos that are culturally responsive and literacy appropriate help participants acquire the knowledge, skills, attitudes, and behavior necessary for nutritional well-being. Our objectives were to develop videos and visual handouts that would enhance the effectiveness of nutrition education with diverse populations, including recent refugees and immigrants.

• Reducing environmental impacts of foothill citrus orchards

  Pest management is a key concern for small-scale foothill citrus growers, but few pest control advisers serve Placer and Nevada counties. Integrated pest management requires a high level of knowledge as well as careful monitoring. Growers must be able to identify pests, assess available tools and develop an effective combination of management methods. Citricola scale has been a major foothill citrus pest for many years, often requiring several sprays per year. In 2003, California red scale began to emerge as a problem in Placer County mandarin orchards.

• UC-FSNEP: Fifteen years of nutrition education to California's families

  Poverty in California is at 13.3 percent, according to the U.S. Census Community Survey published in September 2009. Combined with current economic challenges, this vulnerable population is at risk for food insecurity. The UC-Food Stamp Nutrition Education Program (UC-FSNEP) helps low-income families make healthy food choices, stretch food dollars and increase consumption of California’s agricultural products. UC Cooperative Extension academics and nutrition educators also evaluate educational methods and outreach strategies used with families at risk.

• PE teachers deliver UC-FSNEP EatFit program at Alvord Unified

  Almost one third of youth ages 10 to 14 living in Riverside County are either overweight, obese or are at risk of being overweight. If we focus on children living in poverty, the number increases to 42 percent, according to the 2007 California Health Interview Survey. The survey also reports that 70 percent of Riverside youth ages 10 to 14 eat less than 5 servings of fruits and vegetables daily, 47 percent said they ate fast food two or more times in the past week, 19 percent drank two or more glasses of soda or other sugary drinks the previous day, and only 22 percent are active for at least one hour every day in a typical week.

• Families learn to make every dollar count

  Families with lower educational levels and limited resources make more money management mistakes than wealthier and better-educated families. Providing money management information in formats that appeal to limited-resource families and in a learner’s native language are known to increase financial literacy of less-educated families. International studies have shown that computer-based money management programs are effective in helping less-educated families improve their financial knowledge and decisions.

• Children wash hands to prevent flu and other illness

  In the United States, on average, more than 200,000 people are hospitalized and 36,000 people die from seasonal flu complications each year. To prevent the seasonal and H1N1 flu, the Centers for Disease Control recommends getting a flu vaccine and practicing everyday preventive actions, such as frequent handwashing. Handwashing is easy and the most important step to help prevent the spread of the flu. Yet research indicates that many adults and students do not practice frequent or proper handwashing. In fact, 1 out of 5 people do not wash their hands after using the restroom (American Society of Microbiology, 2005).

• UC research finds 7 more plant families that host cucurbit disease

  The whitefly-transmitted cucurbit yellow stunting disorder virus (CYSDV) infects cucurbits such as melons in several parts of the world. Infection can reduce crop yields. In 2006, CYSDV hurt cucurbit production in the low desert regions of California's Imperial, Coachella and Palo Verde valleys, Arizona's Yuma Valley and in nearby Sonora, Mexico. CYSDV infections were immediate and widespread among fall melon crops in 2006 and 2007 following heavy populations of the vector silverleaf whitefly. A cucurbit host-free period during the summer provided limited success in managing CYSDV, attributed mostly to fewer whiteflies in the Yuma Valley and central Arizona during July. Nearly all fall melon producers in Imperial County have chosen not to plant since 2007. Previous studies had shown that CYSDV was restricted to members of the Cucurbitaceae and lettuce as an experimental host, but we suspected other hosts were affecting the success of the cucurbit host-free period.

• Research Proves Nitrogen Deposition Harms Native Plants

  Research by scientists from the University of California, Riverside has documented the harmful effects of air pollution, specifically nitrogen deposition, on coastal sage scrub and desert native vegetation. The nitrogen emissions originate from automobiles as NOx and from agriculture as ammonium. Nitrogen deposited on the soil promotes the growth of non-native invasive grasses that can quickly replace and out-compete native plants. The loss of native plant communities can displace native wildlife that relies on the native species for nutrition, shelter, or nesting. The spread of invasive grasses has also been linked to increases in the frequency and severity of wildfires. The understory vegetation in deserts and coastal sage scrub consists of native wildflowers that, unlike invasive grasses, provide sparse fuels for fires. Invasive grasses grow quickly when soil nitrogen increases under nitrogen deposition, and provide increased amounts of biomass to fuel fires, which allows fires to spread over large areas.

• Sand backfill improves transplant success of some landscape palms

  Imparting an exotic and dramatic theme, palms are emblematic of California landscapes. Indeed, there is a revival of interest in palms as specimens and accents or to add height, dimension, and architectural interest for homes, businesses, parks and other public areas. Because of their unique root and trunk structure, large specimen palms can be transplanted with a relatively small root ball, creating an instant, mature landscape. The standard industry practice when transplanting palms is to use builder's or washed plaster sand as the backfill medium in order to enhance stability and anchorage, drainage and survival, but the practice had not been scientifically validated.

• Goat milk producers form new association and improve practices

  Goat milk production in California is increasing. Goat milk producers are typically small- to medium-sized dairies who sell their milk to milk processors or cheese makers. There are also dozens of farmstead cheese makers who raise fewer goats but add value to the milk by making their own cheese. Other goat milk products are yogurt, dried milk, canned milk and ice cream. The consumption of goat milk products, especially in the cheese sector, has been rising steadily. Some specialty goat cheese producers report sales increases of 30 percent per year.

• The 4-H Agua Pura fotonovela project

  It has been shown that Latinos are generally interested in environmental issues, and that they are particularly concerned about the health impact of a polluted environment. However, because of language and cultural issues, they are often not engaged in water protection activities.

• 4-H learns about the 'Power of the Wind'

  Sustainable and renewable energy is a hot topic in many circles, and the California 4-H Youth Development Program is joining the movement. A source of energy is considered renewable if it is a natural resource and can be naturally replenished in a relatively short time. Producing electricity from renewable sources will not result in harmful pollutants or emissions and will not harm ecosystems. Renewable energy can be produced using sources like the wind, sunlight, hydrogen, geothermal energy (heat from inside the earth), biomass (energy from plants), flowing rivers, and even the power of the ocean. Renewable energy is also called "clean" or "green" power.

• Farm succession: Helping families nurture the next generation

  A profitable, owner-operated system of agriculture is necessary for the economic well being of our rural communities. Many farmers will retire in the next two decades and younger people are needed to carry on these farm businesses. Young people have little opportunity to enter farming, and even those whose parents have a farm may lose the opportunity because of poor succession and estate planning. Several surveys have found that as many as 64 percent of landowners do not have estate plans. Careful planning is needed for families to provide retirement for the senior members and farming opportunities for the next generation.

• Off-season blueberry production a new options on Coastal California family farms

  Small farms in California are often confronted with economic realities similar to those that plague larger farms. An over-supply of traditional fruit and vegetable crops and chronic low market prices affect many farms in the state. The development of promising new crops is one option that offers California small farmers real alternatives to enhance the diversity of crops they grow and improve small farm profitability.

• A Pilot Study for Improving Energy Efficiency in the Seafood Sector

  It takes energy to process, package and deliver seafood to American consumers. As with other sectors of the economy, the seafood industry would like to become more energy efficient to lower production costs and to market its products as more “green.” Actually implementing conservation strategies, however, can be difficult because it is not always obvious where energy-saving opportunities exist. A simple first step in reducing a company’s energy consumption is to identify its most energy-intensive processes or activities.

• 4-H SET trains volunteers to engage youth in science actvities

  Despite the United State's rich legacy of innovation and global contributions, we face declining proficiencies and workforce shortages in science, engineering, and technology. Nationwide only 18% of high school seniors are proficient in science while only 15% of U.S. college graduates earn degrees in natural science and engineering. The National Science Education Standards emphasize that effective science education requires good educators.

• Managing data-poor fisheries

  The 1998 California Marine Life Management Act (MLMA) provides a guide for the California Department of Fish and Game as it manages coastal fisheries. A key requirement of the MLMA is the development of fishery management plans that are based on estimates of the abundance of a fished species and other types of data-intensive biological and socio-economic information. Unfortunately, essential biological and socio-economic information are lacking in California’s fisheries. This has created a bottleneck to MLMA implementation. New, less resource-intensive assessment methods and techniques are required to move the management process forward.

• Ready, 4-H SET, Go!

  The United States is at pivotal point in its history. Despite our nation’s rich legacy of innovation and global contributions, we are facing declining proficiencies in science, engineering, and technology (SET). Too many of our youth lack the SET literacy needed for careers in the 21st century. Nationwide, only 18 percent of high school seniors are considered proficient in science while a mere 5 percent of all 24-year-olds earn undergraduate degrees in the natural sciences and engineering. The 4-H Science, Engineering, and Technology (SET) Initiative is the 4-H program’s response to our nation’s and state’s concerns for improving human capacity and workforce abilities in these fields. It combines nonformal education with hands-on, inquiry-based learning in a youth development context to engage young people in improving their SET knowledge, skills, and abilities. The California 4-H SET Initiative aims to impact 150,000 new youth members and 15,000 new adult volunteers over the next five years through innovative SET programming.

• Connecting youth with natural resource management

  California's four million acres of rangeland are an important natural resource, providing wildlife habitat, scenic open space and an economic base for many rural communities. Over recent decades, California rangelands have been threatened by invasive weed species, wildfire, concerns over water quality impacts, and conversions of the land to other agricultural uses or to development. Another, perhaps less visible, threat to rangelands is a steady reduction in the number of students preparing for careers in natural resources and range management.

• UC Cooperative Extension helps family farmers comply with labor laws

  Many small farmers in California, especially the 2,000-plus refugee farmers from Laos and Thailand, rely on extended family to help on the farm. Typically, these relatives volunteer or trade labor on each others' farms. Often unbeknownst to the farmers, the state considers the relatives to be employees and a workers' compensation policy is required. The farmers must also comply with other labor regulations. The State of California conducts unannounced "sweeps" of farms (and other businesses) to inspect for violations of labor code, safety and health regulations and payroll rules. In 2005 and 2008, individual Hmong and Hispanic farmers were fined between $14,000 and $26,000 each for non compliance.

• Trap Cropping for Management of Root-knot Nematode by Home Gardeners

  Plant-parasitic nematodes are microscopic roundworms that cause problems for home gardeners. Few control measures are available to California homeowners other than keeping the planting area fallow for two years, or planting nematode-resistant tomatoes. The root-knot nematode, Meloidogyne sp., causes the most serious problem and its effects are readily visible to home gardeners by the presence of knots or galls visible on roots.

• Field trials identify more native plants suitable for urban landscapes

  California's landscape horticulture industry is constantly growing due to population growth, housing expansion and refurbishing of older urban areas. This industry growth requires an almost constant input of new plant material to address a variety of horticultural needs and tastes. Historically, many landscapes were planted with species requiring large amounts of water, fertilizers, and pesticides to remain attractive and healthy. One significant result of this practice has been increasing levels of chemicals in urban water run-off to watersheds, leading to negative impacts on the health of the aquatic ecosystems. In addition to this, widespread use of inappropriate plants in a summer-dry climate can contribute to a shortage of water in areas supplied by seasonal snow-melt. For these reasons, the nursery and landscape industry is in constant need of a supply of new, beautiful, drought-tolerant and disease-resistant plants.

• UCCE investigates how E. coli survives in vegetable fields

  Current evidence from surveys and product testing has shown that California vegetable commodities are rarely contaminated with detectable levels of the human pathogen E. coli O157:H7. However, periodic outbreaks occur. The September 2006 case of E. coli O157:H7 on spinach was a serious example that fundamentally changed the industry and public health landscape regarding food safety measures. To most effectively design risk reduction guidelines and improve food safety management, more information is needed on the biology and ecology of pathogens in actual field production environments. Many studies of E. coli O157:H7 and leafy vegetables are based on laboratory or growth chamber experiments. Many food safety guidelines and policies, by necessity, are based on such studies or on assumptions unrelated to vegetable production. It is imperative that more information be generated from trials involving natural populations of the disease organisms and the microbial-plant-animal ecology as it exists in the field. In addition, we need more information from controlled-inoculation experiments conducted in actual field production settings in California.

• Making food safer for seniors

  Food-borne illness affects one out of four Americans yearly, and the number of cases reported are increasing. Increased cases are due to eating more foods prepared away from the home, emerging food-borne pathogens, an aging population and more young children eating away from home. About 26 percent of food-borne illnesses in California are picked up in community locations, 46 percent in restaurants, 19 percent in homes, and 6 percent in schools. Because of weakened immune systems and ebbing memory, seniors are particularly vulnerable to food-borne illnesses.

• Helping children connect with their agricultural roots

  As more and more agricultural land in Riverside County is converted into housing, children become more distant from their agricultural roots. Gardening exposes children to science and agriculture and increases the likelihood they will eat more fruits and vegetables. Inadequate daily intake of produce by youth and childhood obesity are real concerns. These issues underscore the need to support school teachers in their efforts to start, maintain and use a school garden to promote students' education and health.

• Addressing the Science Literacy Challenge through Educator Professional Development

  It is imperative that individuals be able to make informed decisions about the science and technology in everyday life, yet national and international assessments reveal that the levels of science literacy among youth in the United States are well below those of other developed nations—and the problem is worsening. The root cause of this problem lies in relying on lectures and demonstrations to teach science. These methods provide only a surface level understanding of the nature and processes of science and do not promote critical thinking skills. Furthermore, lectures and demonstrations tend to alienate youth who perceive science as too complicated and irrelevant. Youth science literacy can be improved with the use of Experiential Learning (EL), a strategy that involves direct experience and builds understanding through inquiry and reflection. Experiential Learning is similar to hands-on learning, yet goes much farther by including the discussion and analysis of experiences that deepen and broaden understanding. Teaching strategies such as EL encourage youth to use their own thinking to test ideas, reflect on and analyze information, and predict outcomes. Research indicates that youth retain and learn more when they are taught through experience because they are actively engaged in activities with visible outcomes and demonstrate their knowledge through practice. Those who train educators must model EL as an alternative and effective approach to teaching science. Otherwise, future youth educators will remain unprepared and unwilling to use EL and will continue to teach science with methods proven to be ineffective.

• Teens and driving: What parents need to know

  High-risk driving is one of the most significant threats to the safety of California’s young people. Motor vehicle crashes are the leading cause of death for teens 15 and older. Some of the factors contributing to these higher crash rates include lack of driving experience, risk-taking behavior and distractions from teenage passengers. Parents are in a prime position to influence safe teen driving because they are involved in their teenagers’ driving from the beginning and serve as primary mentors and role models in teenagers' lives.

• UC studies improve the efficiency of weed control in broccoli production

  In broccoli production, a wide variety of techniques are used to control weeds: cultural practices, mechanical cultivation and hand weeding. Weeding costs generally represent a significant proportion of the broccoli production budget, and profit margins can be narrow. In addition, the current debate over immigration reform has increased concern about the availability of labor to conduct hand weeding operations in broccoli and other vegetable crops. Given the labor uncertainties, it is imperative that research be conducted to evaluate techniques that make weeding operations more efficient and effective.

• Summer camp evaluation strengthens programs

  Every year millions of youth spend at least part of their vacation in some camp setting, be it day camp, resident camp or a specialty camp program. Hundreds of children attend California 4-H summer camps each year. Only recently have researchers begun to explore the impact and outcomes of outdoor living experiences on youth and to understand the elements of the camp experience. Are 4-H camps places that nurture children's positive growth? What would make camp programs stronger?

• UC IPM guidelines for strawberries in Spanish

  More than 50 percent of the strawberry growers in California speak Spanish as their first language. While UCCE outreach through Spanish language meetings, various publications and Spanish speaking academics has been serving these growers for a long time, the UC IPM guidelines for strawberry production were available only in English.

• UC delivers oak woodland planning support to California counties

  County-based planning is often an emotionally charged, financially motivated process where decisions can potentially affect natural resources for generations. As Californians move from urban and suburban centers into lands that have historically been hardwood forests, the expansion is impacting the biodiversity and ecological integrity of the state's oak woodlands. The shifting demographics are increasing the need for sound decision making if the ecological integrity of oak woodlands is to be maintained. The UC Integrated Hardwood and Range Management Program (IHRMP) has directed its efforts at planners for the past 15 years in recognition of the importance this dedicated group of professionals have in conserving California's wild spaces. California's oak woodlands are not subject to statewide regulatory oversight as are commercial conifer forests. Consequently, oak conservation measures are often handled by county and private planners on a fragmented, parcel-by-parcel basis. In 2004, the state passed legislation requiring all non-agricultural projects affecting oak woodlands be subject to evaluation under the California Environmental Quality Act (CEQA). Terms of the legislation required that planners must determine the project's “significance” and the impacts must be mitigated. At the time of the enactment, no existing documentation or precedent had been established to assist counties in making such determinations. The IHRMP undertook the task of articulating the complex issue of “significance” and developed a decision matrix designed to assist planners, developers and conservationists address the nuances of the new statute.

• Refractometer calibration test kit developed

  San Joaquin Valley farmers rely on handheld refractometers to determine fruit maturity. A refractometer measures the percentage of sugar (ºBrix) in juice, allowing a grower to estimate a harvest date for a particular variety or field of grapes, peaches or melons. Often a refractometer is purchased and used year after year without being properly maintained or calibrated at the beginning of each season. A lack of calibration prior to each use can give faulty readings, leading a grower to think a crop is ready to harvest, when in fact it may be days or weeks away. Commercial refractometer calibration test kits are expensive and growers rarely purchase them. Additionally, the improper care and/or storage of refractometers will contribute to inaccurate readings. Proper calibration, use and maintenance of a refractometer will improve the accuracy and utility of sugar data in determining fruit maturity.

• Hot water can prevent spread of vine mealybug by grape nurseries

  Vine mealybug is a serious pest of wine, raisin and table grapes in California. Mealybug feeding reduces grapevine vitality, transmits grape viruses, and produces tremendous amounts of sticky honeydew, promoting sooty mold that renders the grapes unmarketable. Until 2002, there was only one localized infestation of vine mealybug recognized outside of Riverside, Kern and Fresno counties. By the end of 2003, infestations had been documented in 16 counties, representing all grape-growing regions of the state. Subsequent investigations identified infested nursery stock as the cause for the rapid, widespread dissemination of this new exotic pest.

• Service-Learning Works for California 4-H Youth

  California communities need active, involved citizens of all ages. Through service-learning projects, teens learn to appreciate the value of contributing to their communities, strengthen their skills, and see themselves as leaders.

• Strategic Supplement Placement Changes Beef Cow Distribution

  Reducing the impact of livestock grazing on water quality, aquatic and riparian habitat, and biodiversity is a continuing goal for livestock producers, natural resource managers, and conservation groups. Environmental impacts of livestock grazing are frequently the result of poor livestock distribution. Management practices that alter livestock distribution on the landscape by attracting livestock away from environmentally sensitive areas can effectively reduce these impacts. However, policy makers, regulators and land managers are often uncertain about the effectiveness of livestock distribution practices and therefore gravitate to the certainty of excluding livestock by fencing or lease termination. This can devastate the economic viability of rangeland livestock enterprises, reducing their competitive ability and adversely impacting the economy of rural communities. Furthermore, livestock exclusion limits our ability to use grazing to manage wildlife habitat, fire fuel loads and weed infestations. It is crucial that managers, regulators and community watershed groups understand how livestock can be predictably and effectively redistributed so that they do not have undesirable effects in grazed watersheds.

• Livestock recycle pears, minimize harvest loss

  In 2006 the pear industry in Lake and Mendocino counties experienced up to 30 percent crop losses due to lack of qualified pickers to harvest the crop. These losses may have been a one-time problem but cull pears happen every year and represent an annual problem to the pear industry. While little can be done to salvage the direct loss of high-grade fruit, an opportunity exists for cattle, sheep and goat producers to recoup some of this loss by turning it into a quality feed source.

• Nature of a beet cyst nematode population suppression unraveled

  Tiny parasitic roundworms (nematodes) that typically feed on underground plant parts are responsible for an estimated $10 billion in crop damage in the U.S. Nonchemical management of these pathogens has progressed slowly. No biological control product against plant-parasitic nematodes has ever received California EPA registration. The lack of understanding of microbe-nematode interactions is perhaps the greatest impediment to significant progress. Nematode-suppressive soils are soil sites where conditions for nematode-caused crop damage are present, but where such damage does not occur or where it occurs at a much lower level than expected. These are often sites where biological control occurs naturally and plant-parasitic nematode populations are typically maintained below the economic threshold.

• Youth learn leadership at state 4-H conference

  A critical element in positive youth development is empowering youth and allowing them to make a difference in their communities. Youth development research suggests that developing citizenship, leadership and life skills can benefit youth and their communities. This can be accomplished, in part, through opportunities for youth to participate in governance and rule making, and to take on leadership roles.

• The National Animal Identification System Information Education Project: Addressing 4-H Stakeholders’ Issues and Concerns

  4-H Animal Science projects, which engage approximately 30,000 youth annually in California, pose potential risks to biosecurity and animal disease traceability. The majority of projects focus on rearing, care, husbandry, and showing and marketing live animals, including poultry, ruminants, and swine. There is a lack of standardized guidelines or protocols for tracking 4-H project animals. There are also no regional or statewide systems to inform volunteers of biosecurity risks and preventative measures. A standardized electronic tracking system that is currently voluntary in California may become mandatory, as it is in some states. The National Animal Identification System (NAIS), established in 2002, provides animal health officials with disease tracking tools to protect animal agriculture during a disease outbreak. NAIS uses an animal-specific Animal Identification Number (AIN) and a site-specific Premises Identification Number (PIN) to provide trace-back data on at-risk animals within 48 hours of exposure or potential exposure. While the system offers a standardized means of identifying and tracking animals, there have been concerns among California 4-H volunteers and youth regarding NAIS, including its potential impact on Animal Science projects.

• Spread of tomato yellow leaf curl in California tomatoes arrested

  Tomato yellow leaf curl virus (TYLCV) is the most recent whitefly-transmitted virus disease to appear in Imperial County. The disease caused by TYLCV in tomato crops is the most destructive whitefly-transmitted virus disease of tomatoes worldwide. TYLCV threatens commercial tomato production in California, transplant production of peppers and tomatoes in Imperial County, and home garden tomato production. TYLCV is transmitted by adult silverleaf whiteflies and can spread rapidly, but TYLCV is not seed borne or transmitted mechanically. The presence of silverleaf whitefly host plants, both cultivated (such as peppers and tomatoes) or wild hosts (such as sowthistle, cheeseweed and nightshade) during spring and summer may lead to whitefly migration and spread of TYLCV. Immediate action was needed to inform tomato growers of the new threat to their industry and to attempt eradication of TYLCV from California.

• Management practices to conserve water and reduce off-site movement of sediment and pesticides in drainage waters

  Drainage waters discharged from irrigated fields in California and other states are under ever-closer scrutiny. The quality of drainage waters discharged into waterways in California is regulated under California Water Code and Federal Clean Water Act. Growers that discharge drainage waters that could affect the quality of water bodies in the state are required to comply with water quality regulations. Compliance with water quality regulations could be achieved by filing a Report of Waste Discharge (RWD) that complies with state-prescribed Waste Discharge Requirements (WDRs). WDRs could be used as a permit, limiting the levels of pollutants that may be discharged in waterways to protect the beneficial uses of water bodies in the state. Complying with the Irrigated Lands Conditional Waiver Program or the Total Maximum Daily Load (TMDL) limits may provide alternates to WDRs for growers in the state. Sediment, nutrients and pesticides in drainage waters have been identified as the leading cause of water quality impairments in rivers and other water bodies in California. For example, sedimentation/siltation TMDLs for agricultural drains and two major rivers in Imperial Valley have been implemented to address water quality problems in the Colorado River Basin of Southern California. Accurate and reliable estimates of the load of sediment, nutrients and pesticides in drainage water are needed to assess the quality of drainage water or to comply with WDRs.

• Self-Help Kiosks Used to Extend IPM Information to Gardeners

  Pesticides used by home gardeners can contribute to water pollution if the chemicals get carried away in runoff. To minimize pesticide use, home gardeners need an interesting and easy way to identify pests and learn the least-toxic, science-based methods of controlling them. While much information is available online (www.ipm.ucdavis.edu), not all consumers are Internet users and must often depend on untrained store personnel or anectodotal information about how to treat pests in and around their homes. More often than not, a pesticide treatment is recommended, even if the pest has not been clearly identified.

• UC’s olive oil taste panel supports industry

  The California olive oil revival is a quiescent industry come dramatically to life. Acreage planted to oil olives has doubled in just the last five years to over 10,500 acres. California’s production of 400,000 gallons of premium quality olive oil is predicted to triple in the next three years and continue to grow. These oils are excellent, taking top awards in competitions all around the world, but this was not always the case. Only a few years ago, most producers in California had no idea what good olive oil tasted like and some, unfortunately, were producing and selling defective oils without knowing it. Much of the old traditions of the Mediterranean countries that were being adapted included some of the bad habits of processing oil using antique and limited resource technology that produced defective oils. The big question was, how could California olive oil producers ever develop a viable industry without recognized standards?

• Long-term work yields avocados resistant to disease

  The most devastating disease of avocado in California and the world is Phytophthora cinnamomi, or avocado root rot. In unprotected orchards, this disease can destroy virtually every tree within a few years, and put at risk the $400 million dollar California avocado industry. Fungicides have been used extensively to try to control the disease, but the ultimate control is a rootstock that is resistant to the fungus that causes the disease.

• UCCE Helps Growers of Ornamental Eucalyptus Ravaged by an Invasive Pest

  Baby blue gum eucalyptus is grown for the production of fresh cut foliage for flower arrangements or it is dried, dyed and sold in preserved floriculture markets. It has been grown commercially in California from San Diego County to Sonoma County for 40 years. There is no other significant commercial production of baby blue gum elsewhere in the United States. Ornamental eucalyptus has been virtually pest-free, requiring only occasional pesticide treatments. However, in August 2003, tortoise beetles (Chrysophtharta m-fusca Boheman) were observed on ornamental eucalyptus in Orange County, Calif. Within a few years, this leaf-feeding beetle spread throughout Southern California in the major growing area of ornamental eucalyptus, and has caused very heavy feeding damage to terminal growth. In 2006, beetle populations in growing regions reached extremely high levels, resulting in nearly complete crop loss.

• UC spotlights solutions to dairy water pollution challenges

  Milk is California's number one agricultural commodity, with a farmgate value of more than $5 billion annually. Although the state has fewer dairy farms than it did 20 years ago, the average herd size has increased. Dairy producers are faced with increasing scrutiny and more stringent regulations. In May 2007, the Central Valley Regional Water Quality Control Board adopted new dairy “waste discharge requirements” that impose stringent nutrient management and monitoring practices on the region’s 1,500 dairies.

• Public Land Grazing Is Important to the Conservation of San Francisco's East Bay Private Rangelands

  Many important natural resource lands in the Bay Area are privately owned by ranchers, and others are leased by public agencies to ranchers for grazing. These lands provide forage and numerous other ecosystem services, including those valued highly by the public, such as a pleasing landscape and wildlife habitat. It is well-known that the private land is at risk of fragmentation and development, when ranchers decide to sell their lands. What role does the availability of public lands play in their decisions? How important is public land in the ranching enterprise and to the local industry? This study addressed these questions to assess the role of public land grazing in East Bay land conservation efforts.

• Carrots are not only orange

  Contrary to the popular belief that carrots are only orange, the common root vegetable is available in a wide variety of colors -- from white to red to almost black. The unusually pigmented carrots have flavors that can accommodate many tastes. Flavor and visual variety may entice consumers to purchase and eat more carrots. A rainbow of carrot colors could attract customers to a roadside stand or farmers market booth, increasing traffic. In addition, colorful carrots might provide a nutrition boost for health-conscious consumers. For instance, according to the USDA, yellow carrots contain xanthophylls, a substance that supports vision and lowers lung cancer risks. Red carrots contain lycopene, which helps prevent heart disease and some cancers, including prostate cancer. Purple carrots contain anthocyanins, pigments that act as powerful antioxidants to neutralize harmful free radicals. Anthocyanins also regulate blood clotting, a helpful factor in preventing heart disease. White carrots lack pigment, but may contain other health-promoting phytochemicals.

• Off to a Good Start...Getting Children Ready for Kindergarten

  Studies show that as many as half of California’s kindergarteners entering school are struggling. Learning and reading difficulties are more common among poor, non-white and non-native English-speaking children. However, problems exist in all socio-economic groups. Kindergarten teachers often cite early education in the home as the most important strategy to improve school readiness. Parent-child relationships in early childhood predict social and emotional development and lay the groundwork for academic growth and success. Likewise, a child’s readiness to enter kindergarten predicts future academic success and failure.

• UC's Pima Cotton Research Bolsters California's Cotton Industry

  Elevated world demand for fine garments and quality textiles has lead to improved prices for select high grade cottons. California growers produce nearly 90 percent of the nation's highest quality cottons, known as Pima or ELS (extra long staple) types, prized for their long, strong and fine fiber. Because Pima yields are considerably lower than that of the conventionally grown upland cotton types, gaining domestic and world market share while remaining profitable is risky business. Variety development and testing programs are an integral part of identifying new germplasm that has the potential to meet the market demand for a high-quality product and the grower need to remain profitable.

• Converting urban yard waste to avocado root rot management

  In 1990 the California Assembly passed a bill calling for the reduction in materials going to landfills. A large portion of this material is urban yard waste, or green waste. For many years researchers at UC have been working on the nagging problem of how to control one of the most devastating diseases in avocado – Phytophthora cinnamomi or Avocado Root Rot. This disease affects 60 percent of the avocado acreage in the state. One of the treatments that had been examined was the use of organic materials as mulches, such as composts, manures and yard waste.

• Research provides stable fly monitoring and control tools

  High levels of stable flies on dairies are more than a nuisance. The bites also reduce milk yields. To keep stable flies at bay at dairies, it is standard procedure for dairy operators to hire a pest control service that sprays the premises with pesticides every two weeks during fly season, at an average cost of $250 per treatment. Because of pesticide resistance developing in the insect population, such sprays for stable flies are rarely effective. This management practice wastes dairy resources, adds to the pesticide load in the environment, and leads to increased pesticide resistance.

• Regional marketing—A competitive niche for small and mid-scale growers

  An increasingly competitive global marketplace combined with higher input, labor and land prices have put pressure on many small and mid-scale growers throughout the state. As a result, many growers are looking to diversify their markets such as taking advantage of local or regional marketing. Consumers are demanding more food from local growers. Regional supplies mean that food is often fresher, and has traveled less distance from "farm to fork," thereby reducing ever-increasing fuel costs. More growers and their associations are beginning to establish “place-based” logos or labels as a way to create and maintain the value of their products and contribute to the economic viability of their operations.

• Choosing a landscape company with environmentally sound practices

  For many years, we have worked with local agricultural producers to develop sound management practices to alleviate water quality and other environmental problems. Many of the legal requirements faced by the growers are a result of the concern of homeowners and other non-farming groups. Ironically, in many situations, the environmental impact of a large housing development can be equal to or greater than the impact of the farming operation. However, many residents do not understand the collective impact of their home and garden pest control and fertilization activities on the environment. In addition, most of these homeowner activities are generally unregulated.

• Monterey County Lab To Assist in Biosecurity Efforts

  Biosecurity refers to safeguarding our national and state agricultural industries from damage caused by introduced plant pathogens and pests. Biosecurity plant pathology programs address two potential sources of introduced threats -- the unintentional, accidental introduction of exotic pathogens from outside the state or country and the intentional, deliberate introduction of damaging pathogens by factions antagonistic to our nation. Deliberate acts can be considered bioterrorism. In response to the attacks on Sept. 11 and the increased concerns about terrorism worldwide, the United States established a program to heighten awareness and detection of introduced plant pathogens and pests. The National Plant Diagnostic Network (NPDN) is a nationwide program that focuses on finding and identifying introduced plant pathogens, communicates such findings to appropriate network authorities, and trains professionals in various fields to look for these possible new threats. NPDN coordinates and organizes researchers, plant pathologists, extension personnel, regulatory agents, and industry members into a national network.

• Potato Evaluation Program Helps California Growers

  California is a major producer of fresh market potatoes in the United States. All types of fresh market potatoes (including russets, whites, reds, yellow fleshed, and specialty) are grown in the potato production regions of California. The growing conditions for these potatoes are significantly different in California, particularly in Kern County and other Southern California locations, as compared to other potato growing areas in the United States. While California is a major producer of fresh market potatoes, there is not an organized statewide breeding program to accommodate the unique needs of California potato growers. Hence, he potato industry in California has relied on the USDA and out-of-state universities for the development of improved varieties. The varieties are screened and evaluated for their adaptability to California growing conditions, giving particular consideration to the warmer and drier conditions of Southern California.

• Researchers find wasp can control spotted gum psyllid

  In August 2000, two psyllid species were discovered on lemon-scented gum and spotted gum trees in the Anaheim area. One is the spotted gum psyllid, a lerp psyllid, and another is the lemon gum psyllid. The insects cause leaf damage and drop which can stress trees and make them susceptible to fatal attack by other insects. Psyllids suck sap from leaves and produce a sticky substance called honeydew, which drops to the ground on cars and sidewalks.

• Fire in California's Oak Woodlands

  Fires in California have become all too common during the past two decades. What is especially troubling is that large, catastrophic wildfires resulting in significant property losses seem to be increasing in regularity. Oak woodlands will no doubt continue to be affected by these conflagrations. One reason wildfires are increasing in severity is the build-up of fuels, at least partially the result of effective fire suppression efforts during the last century. There are more fuels on the landscape today, especially in the understory, and the fires that start are more likely to become large in scope.

• Oak Seedlings Can Be Established on Grazed Rangelands

  For nearly 100 years, there has been concern that several native California oak species are not regenerating adequately to sustain populations. Inadequate regeneration could adversly affect woodlands, resulting in conversions to shrub fields or bare pastures. A principal factor believed to significantly contribute to poor oak regeneration in California is livestock grazing. Since approximately 80% of California's oak woodlands are privately owned and the principal activity on many of these lands is livestock grazing, it is vital to understand how oaks can be regenerated in the presence of livestock. Such information will help ensure that our oak woodlands remain healthy and productive.

• Mini Watermelon Research Benefits California Farmers

  Four types of watermelons are available in supermarkets. Older diploid (seeded) watermelons, grown since 1629, weigh 18-35 pounds. Large seedless triploid watermelons weigh 15-22 pounds and have been popular since 1988. Icebox-size melons, 6-12 pounds, have been available since 2000. The newest melons are seedless mini or “personal” watermelons, sometimes called “palm” melons. The new triploid one-serving melons, weighing 3-7 pounds, became widely available in markets in 2003. Besides the smaller size, advertisers tout its thinner rind, which means more edible flesh. California growers started growing the personal-size melons, but research was lacking for recommended varieties, quality characteristics, pollinators and spacing requirements.

• Sheep Shearing School Improves Wool Quality and Creates Jobs

  The lack of qualified shearers is a major problem for both the range and small flock sheep operations in Mendocino and Lake counties and statewide. The skills needed are difficult to learn without "hands-on" training. Sheep shearers are also often a source of educational information about management and health care and play an important role in delivery information to their clientele - the sheep producers.

• Conservation Tillage Workgroup Introduces New Tillage Alternatives

  Conservation tillage (CT) production systems have been developed in a number of regions around the world for crops such as corn, wheat, cotton, and soybeans . Widespread adoption of CT practices for these crops is common in South Dakota, Iowa, Georgia, Australia, and Brazil; however, CT currently is used on less than 2 percent of California's annual cropland. CT production may be a means for improving production economics of farming systems while also sustaining air, water, and soil quality; but, little research-based information and experience about CT is available that addresses California’s diverse production environments.

• Conservation Tillage Cuts Costs in Tomato Production

  Rising fuel and labor costs oblige growers to carefully cut production costs. Reducing intercrop tillage typically associated with bed preparation operations is a promising means to cut costs in tomato production systems. A variety of “conservation tillage” (CT) crop production systems have been developed in other regions for crops such as corn, wheat, soybean, and cotton. To what extent, though, might CT principles and practices be adapted to tomato production in California?

• UC Riverside Researchers Improve Drought Tolerance in Plants

  Diminishing water resources, climate changes brought about by global warming, and drought conditions in many arid and semi-arid regions of the world are making it increasingly difficult to grow viable crops. Rainfall in California has been below normal in recent years, raising concerns that the state may be experiencing another of its periodic droughts. And in the sub-Saharan area of Africa where many regions depend on rain-fed agricultural production, rain can be extremely scarce and the rainy season short. On top of this, there will be enormous needs for increased food production over the next 50 years. Current projections are that the global human population will increase from approximately 6 billion currently to between 8 and 12 billion around 2050.

• UC Riverside Researchers Develop Low-Carb Corn with Enhanced Protein and Oil

  Projected world population growth from the current 6 billion to between 8 and 12 billion by the year 2050 is expected to outstrip food production. Over the last several decades, the Green Revolution has yielded many improvements in agricultural practices that increased crop productivity in the world’s most important cereal grains. But the agricultural practices adopted during the Green Revolution are unlikely to generate the productivity gains needed in the future.

• Training Health Care Providers Helps Protect Farmworkers from Pesticides

  One important way to improve pesticide safety for farmworkers is to provide health care workers with training and resources to help them in recognizing and treating pesticide-related illnesses and injuries. Small, rural health clinics located in farming communities generally serve California’s farmworker population. These clinics often experience frequent staff turnover, so educators must use innovative methods to provide timely pesticide information and clinical training.

• Protecting the Environment and Human Health Through Worker Training

  Keeping pesticides out of groundwater and surface water and preventing pesticide drift are two of the most important issues facing agriculture. At the expanding agricultural-urban interface, the spotlight on these issues intensifies. Pesticide applicators are directly responsible for ensuring that pesticides do not contaminate water or drift off the application site. Their supervisors play an important role in deciding when and how to use pesticides.

• Study Manual Series for Commercial and Private Pesticide Applicators

  Since pesticide and pest control regulations are very complex, anyone who uses or supervises the use of restricted materials must be certified. Commercial applicators must pass at least two qualifying examinations administered by the California Department of Pesticide Regulation. Private applicators are certified by passing an examination given by county agricultural commissioners. Until UC experts stepped in, however, all those studying for the exams struggled to glean the information they needed from various sources.

• CE Helps to Solve Disposal problem in eradicating Exotic Newcastle Disease.

  In October, 2002, a devastating foreign animal disease was discovered in several small flocks of chickens in Southern California. By December, Exotic Newcastle Disease had spread to large commercial flocks of egg-laying chickens. To eradicate the disease, over 3.5 million chickens had to be euthanized and disposed of. Sending the dead birds to landfills was the safest and most feasible option for disposal. At the time, covering the carcasses with several feet of compacted soil was the only accepted method of disposal. However, not enough soil was available at the landfills to dispose of so many carcasses in that way. Some other method of burial had to be developed.

• Salt Tolerance of Landscape Plants for Reclaimed Water Irrigation

  Water is a limited natural resource for most of the arid and semi-arid regions of the United States. Despite this, rapid population growth and development are occurring in these areas, especially California. Many municipal water providers are faced with the need to reduce demand for freshwater supplies while protecting against drought and cutting down on wastewater discharges into sensitive bays and estuaries. Agencies encourage the use of reclaimed or recycled water from wastewater treatment facilities for appropriate non-potable uses, including urban landscape irrigation. In 2000, 19.5 percent of recycled water in California was used for landscape irrigation, saving enough fresh water to supply 300,000 homes. An important caveat to the use of reclaimed water for landscape irrigation is that after most of the water treatment processes, sodium chloride is the most detrimental chemical compound remaining in the recycled water. Little information is available on the tolerance of common landscape plant species to the levels of salts found in reclaimed waters. This basic information is needed by landscape managers to ensure the maintenance of healthy landscapes, given the reality of increased use of reclaimed water for irrigation.

• Empowering Food Stamp Recipients for a Better Future

  The first goal of the Food Stamp’s Nutrition Education Program (FSNEP) is to empower families and individuals to help themselves. FSNEP offers food stamp recipients and applicants the "tools" to make positive changes in their lives. These tools range from motivating recipients to eat healthier diets to teaching families how to cook in order to prepare better foods at lower costs; teaching life skills that enable recipients to get and keep a job; teaching basic survival skills such as how to get out of debt, how to shop to save money, how to use community resources; introducing food safety skills to reduce food borne illness; and helping children learn better eating habits and the importance of physical activity.

• A Nutrition Education Program That Helps Families Make Healthful Choices

  People who are most "food insecure"--those unable to use traditional means for acquiring and managing their family food supply--are at greater risk for obesity and poor health. That fact, confirmed by a recent UC study, is one reason that poor health is more common among low-income and minority populations. Obesity is not just a matter of personal health. It is a costly and deadly public health concern that affects economic productivity and state budgets as well as personal and family well-being.

• Engaging Latino community volunteers

  Supportive communities with residents committed to and involved in the nurturing of youth contribute significantly to the healthy development of children and their families. The increasing cultural diversity of California communities and other social phenomena, such as working parents and changing family compositions, bring new challenges to UC Cooperative Extension programs that rely on volunteer participation. With Latinos now comprising one-third of the population of California, understanding the dynamics of Latino involvement in community life is essential to designing community programs to attract the participation and meet the needs of Latinos and their families.

• Grow Food Safely in Urban Gardens

  Many urban residents grow much of their own food in backyard or community gardens out of necessity and/or as a hobby. However, any place subjected to human activity is likely to have potentially harmful trace elements at elevated levels in the environment, particularly in the soil. Trace elements, especially heavy metals, can accumulate in the soil and on plants, and may pose a potential health risk to people who breathe or, especially, swallow contaminated soil or eat contaminated vegetables, especially young children.

• Economic study helped determine growers' compensation for vineyard losses

  From 1998 to about 2000, more than 40 percent of the Temecula Valley vineyards were removed due Pierce’s disease, which is spread by the glassy-winged sharpshooter. In 2000, the California Department of Food and Agriculture received money from the federal government to provide compensation to growers and alleviate the impact of their losses caused by this disease. In order to process the amount of compensation, both the growers and CDFA required current information on production practices and costs of establishment for winegrape production in the impacted areas.

• Helping Clinical Laboratories Standardize Farmworker Tests

  Growers are required to test the blood of pesticide mixer loaders, applicators and others who contact organophosphate (OP) and organocarbamate (CB) pesticides -- such as diazinon and carbofuran -- in the workplace. Barry Wilson, animal science and environmental toxicology professor, his students and colleagues showed that tests used by California clinical laboratories often were not optimal and that results were not comparable from laboratory to laboratory. This led to a change in state regulations requiring that mandatory tests be consistent and conversion factors be generated.

• Outbreak of new disease affects almond orchards statewide

  During wet years in the 1990s a new and unknown plant disease, later identified as an anthracnose fungus, occurred throughout most of California's almond growing region. It destroyed flowers and developing nuts, producing toxins that killed almond tree branches up to two inches in diameter. Losses continued throughout the season whenever rains occurred. Growers were at a complete loss for control of this disease and believed they might have to remove the affected orchards. Processors also were concerned because nuts infected near harvest could have internal discoloration that was difficult to detect and reduced product quality.

• Community Agency Learning (CAL) Series

  Because over half (55%) of all California children ages 5 to 14 have both parents or a single parent working at least 30 hours per week, after-school programs are critically needed and play an important role in the lives of many children. The most important factor in the quality of this care, according to the RAND Corporation, is the quality of staff. However, maintaining staff quality is challenging due to factors such as funding uncertainty and short work hours. Although staff generally do not have teaching credentials, they are increasingly called upon to improve the academic work of low-achieving students. When that happens, traditional teaching methods that have failed the student during the school day are unlikely to succeed in after-school programs.

• Grass Fed Beef, A Way to Preserve Open Space in California

  A large part of California's open space and wildlife habitat is provided by ranchers, whose yearly return on their investment ranges from 3% down to minus 4%. In addition to this economic squeeze, increasing urban encroachment is limiting the sustainability of these open spaces. Marketing grass-fattened beef directly to the consumer could provide both a higher return to ranchers and a product that has many health advantages for consumers.

• Protecting grazed annual ranges

  In the early 1980s, managers of grazing on California’s annual rangelands were beset with a host of problems exacerbated by drought. A simple and yet scientifically defensible method for determining grazing capacity and regulating grazing intensity was needed. The available science was primarily based on work by federal agencies outside of the state and on perennial-dominated grasslands.

• An Alternative to Honey Bees for Pollination

  Managing bees for pollination is becoming more difficult as beekeepers face challenges from the Africanized honey bee, the Red Imported Fire Ant, Varroa and tracheal mites and several other pests and diseases. Colony strength, winter survival and restrictions on movement of bees in to and out of the state all affect the economics of beekeeping. Growers who rely on honey bees for pollination are concerned about future availability of bees as well as increasing costs for pollination. Leafcutter bees are used for pollination on certain crops in Canada and the Pacific Northwest, but they had not been used in California due to their higher cost and more intensive management requirements. If leafcutter bees could be used to pollinate several commodities in this area, there would be greater incentive to establish the necessary infrastructure, the cost would go down, custom pollinators might become involved and more growers could take advantage of the leafcutter bee's superior pollinating activity on certain crops.

• Lowering Food Allergies

  Common staples like cereal grains and milk provide critical sources of nutrition for many people, but can cause problems for people with food allergies. A food allergy is an abnormal response to a food triggered by the immune system and it can result in diarrhea, vomiting and in the worst cases is life-threatening. Two foods that cause allergies in children, milk and wheat, do so because certain of their proteins are held together tightly with chemical "bungie cords" and are not digested. The allergens then interact with target cells in the small intestine, causing an allergic response.

• UC biotechnology website helps the public understand GMOs

  Thomas Cardinal Wolsey gave this warning in the late 15th century, “Be very, very careful what you put into that head, because you will never, ever get it out.” His admonition still resonates today relative to the impact of information people receive about genetically engineered (GE) crops and foods. It is the responsibility of public sector scientists to provide facts to inform consumers about issues being raised over crops and foods developed through the process of genetic engineering (biotechnology, genetically modified, or GM). This helps individuals make informed decisions about the desirability of the technology and its products.

• Nematologist Works on Resistant Grape Rootstocks

  Grape vines are susceptible to diseases caused by various nematode species, including root-knot, root-lesion, ring, citrus, and dagger nematodes. Research has indicated that root-knot nematode species often adapt to invade previously resistant rootstocks within two to 14 years after planting. Once nematode populations develop the means to exploit one rootstock, they are then able to attack all the plantings using that rootstock. The damage caused by nematodes is economically significant, resulting in lost fruit and vine vigor for growers.

• Mulches Used to Control Avocado, Citrus Root Rot

  Phytophthora root rot of avocado and citrus is a worldwide problem, causing the potential destruction of avocado orchards and reducing fruit quality and yield for citrus. It is estimated that some 60 percent of California avocado orchards are affected by the disease.

• Agricultural Labor Management – Conflict Management: A New Approach

  Despite the enormous strides made in modern negotiation and conflict management theory, practitioners sometimes find themselves floundering. In the traditional approach, mediators bring the contending parties together where each has the opportunity to explain his or her side while the other side listens. In reality, this approach often increases the contention between the stakeholders. Also, in this traditional approach mediators tend to take a very active part in the process, where stakeholders talk to the other party through the mediator rather than addressing each other directly. One of the concerns with this conventional approach is that mediators often take on the role of arbitrator in the process.

• Dairy Quality Assurance Animal Health and Well-Being

  Consumers have targeted marketing organizations such a chain restaurants and grocery stores with questions on the “humaneness” of production practices utilized in food animals. The California dairy industry has campaigned their products to the consumer with sayings such as “Happy cows come from California.” With the evolution of these ads -- along with consumer queries -- animal protection organizations have responded by filing national and state law suits, which have yet to be successful in court but which have actively used the media to raise consumers’ concerns for the well-being of dairy animals. This has paralleled the on-going development of an animal welfare module which will be included in the voluntary California Dairy Quality Assurance Program.

• Cost-benefit Analysis of Gasoline Additives & Environmental Effects

  Methyl tertiary butly ether (MTBE) was added to gasoline as an oxygenate to reduce air emissions in the state of California as well as other regions. However, lacking a comprehensive assessment of all impacts to the environment prior to adding MTBE, California is experiencing widespread contamination of groundwater and surface waters as well as formaldehyde air emissions, posing a carcinogenic threat to humans. A cost-benefit analysis was needed to evaluate the gasoline blend with MTBE versus alternatives.

• Home Gardener On-Line Publications

  In light of the increasing need to bring up-to-date information on landscaping and gardening to urban audiences, the web offers an efficient way to provide on-line information in an accessible format to home gardeners and horticulture professionals.

• Identifying sources of Xylella fastidiosa in Southern California Vineyards

  In the early 2000s, the grape industry in the Temecula Valley suffered tremendous economic losses resulting from an epidemic of Pierce’s disease, a lethal disease of grapevines caused by the bacterium Xylella fastidiosa. Leafhopper insects, primarily the glassy-winged sharpshooter, transmit this pathogen from plant to plant. The bacterium can also infect several other species of plants that can serve as sources of inoculum for infection of grapevines. The identification and removal of infected plant material from grape-growing areas is critical to the successful management of Pierce’s disease.

• California Hardwoods Provide Economic Development Opportunities

  California hardwoods are an underutilized natural resource. California is a major consumer of hardwood lumber (20 percent of nation’s production) but the hardwood lumber production industry in the state is almost non-existent; this is in spite of a sizable hardwood tree resource (12 billion cubic feet of timber growing stock). The economic viability of a native hardwood lumber industry depends on a thorough understanding of the lumber recovery and grade yield expected from the resource and a solid knowledge of wood properties and manufacturing characteristics. The focus of this effort is to encourage a sustainable California hardwood industry by identifying basic industry needs, raising the awareness of the potential for value-added products, developing good manufacturing practices, and providing technical assistance.

• Increasing Use of the Earned Income Tax Credit (EITC) by Low-Income Families

  The Earned Income Tax Credit has been described as the largest and most successful federal assistance program for low-income working families. Last year, the EITC was responsible for elevating the families of 5 million children above the federal poverty line. However, many eligible families do not take advantage of this valuable income supplement for various reasons, as indicated by the findings of Rural Families Speak. Rural Families Speak is a longitudinal study assessing changes in the well-being of rural families in the wake of welfare reform and associated reductions in programs and services. In the first year of the study, only about one-third of the Latino participants who were eligible for the EITC had actually received the credit. The data indicated that lack of and/or inaccurate information were common reasons for non-receipt. Language and cultural barriers further diminished the likelihood that Latino families knew about and claimed the EITC.

• California Processing Tomato Variety Evaluation

  Tomatoes are the leading processed vegetable crop in California. Annual production is about 10 million tons of fruit, grown on more than 260,000 acres and with a total on-farm value exceeding $608 million. Processing tomatoes are grown throughout the state and in many soil and temperature regimes. Under such diverse growing conditions, the performance of different varieties also varies greatly. One that does extremely well along the Central Coast may simply not set fruit out on the West Side in Fresno County.

• Exotic Newcastle Disease (END) Eradication Efforts

  Exotic Newcastle Disease (END) is a catastrophic avian (bird) disease. An outbreak was confirmed October 1, 2002, and Southern California is under state and federal quarantines. As new pockets of the disease have been identified, states of emergency have been declared in California, Nevada and Arizona.

• California Youth Earn National Awards at 2002 Horticulture Convention

  California is the number one horticultural state in the U.S. and has a sizable proportion of the nation's population, yet awareness of horticulture among its youth is questionable. Very few California youth have represented California in horticultural competitions in recent years, and only one in the past 10 years. This is a problem, since such young people are the future leaders of California horticulture.

• Mite devastating date crop is foiled

  Riverside County is the number one producer of dates in California as well as the nation but successful, economical production is limited by Banks grass mite (BGM), the leading pest of dates in the state. Sulfur is the only registered pesticide for use in controlling BGM. However, sulfur disrupts natural enemies and no longer controls BGM. Alternative chemicals must be found.

• ANR Research Clarifies Role of Tree Species in Air Pollution

  Trees and shrubs help clean the air. They absorb carbon dioxide, release oxygen and provide surfaces for the deposition of airborne particles and unhealthful gases such as ozone. Also, water evaporating from tree leaves cools the air and shade from trees cuts energy consumption, reducing the need for air-polluting energy generation. However, there is another side to the story. Some trees and shrubs emit high rates of certain volatile organic compounds (VOC), which react with nitrogen oxides (NOx) and sunlight to form ozone, a ground-level pollutant. Other plants emit very little VOC.

• Citrus Program Protects Health of State's Trees

  California citrus growers often want to import foreign citrus varieties to develop new product lines and extend growing seasons. To protect the state citrus industry from devastating diseases, all foreign budwood entering California must go through an official inspection service, which will quarantine, test, and, if necessary, cleanse the citrus tissues to ensure that they contain no pathogens. Also to protect the industry, the state requires that nurseries and commercial growers propagate new trees either from their own state-registered trees or from budwood increase blocks grown from buds from a registered source.

• 4-H Youth Development: Fostering Civic Engagement

  How do we help young people understand and effectively participate in the political and social processes and institutions that shape our society? How do we prepare and encourage youth to become engaged, competent civic leaders? In response to the events of September 11, 2001, there is increased national attention to these questions. Researchers, educators and others need to identify effective strategies for engaging diverse youth in their communities and preparing them for active citizenship.

• 4-H Youth Development: Reaching Diverse Audiences, Building Understanding of Diversity

  California is the most ethnically diverse state in the nation. It has 35% of all Latino children in the U.S., 30% of all Asian and Pacific Islanders and 14% of all Native Americans (Children Now, 1992). Approximately 62% of California’s youth under age 18 are children of color. Additionally, California leads the nation in the number of new immigrants. In order to function effectively and successfully in today’s world, our youth must learn how to work well with people from a wide diversity of cultures and backgrounds.

• 4-H Youth Development: Advancing the Field of Youth Development

  Much research has documented the important role that out-of-school activities play for today’s youth: preventing risky behaviors such as drinking, drug use, or juvenile crime; providing safe and engaging environments for young people to continue learning; and promoting healthy youth outcomes and developmental assets. There are a wide range of organizations and approaches to youth development, but a shortage of research on which approaches work best, and under what conditions. Youth development organizations feel pressure to develop tools for measuring outcomes, but do not always have the resources to accomplish that task.

• Ranchers Voluntarily Protect Rangeland Water Quality

  Livestock grazing and associated ranch practices may pollute surface water if not properly managed, a great concern to downstream water users and state regulatory agencies. Increased sediment from grazing induced soil erosion; increased stream temperature from removal of streamside vegetation and nutrient loading have the potential to degrade aquatic habitat that is important to several endangered species. Improper management of livestock may result in pathogen loading that can impact domestic water sources. In 1989, the range livestock industry identified water quality as a high priority issue and in 1990 began discussions with the State Water Resources Control Board, UC Cooperative Extension, USDA NRCS and the California Association of Resource Conservation Districts about a voluntary program through which ranchers address clean water issues on their own propery. These discussions led to the development of the California Rangeland Water Quality Management Plan (CRWQMP).

• Biological Control Research Helps Address New Avocado Pests

  Two exotic pests, avocado thrips and persea mite, appeared in California in 1990 and 1996, respectively. A model based on 1998 harvest data predicted that growers in the state, who produce about 95 percent of the nation's avocado crop, would experience an estimated $13 million in short-term losses, with annual losses decreasing to $6 million as the industry developed means to deal with the pests. After more than four decades of largely pesticide-free insect control, many avocado growers now find it necessary to spray their orchards to minimize foliage and fruit damage.

• New Rice Varieties Keep the California Industry Competitive

  Improved rice varieties that meet the changing needs of diverse domestic and world markets are central to keeping the California rice industry economically healthy and rice farmers in business. High quality and reliable supply are keys to sustaining the industry.

• Collaboration Develops Improved Avocado Maturity Test

  Since 1983, the Avocado Inspection Program of the California Department of Food and Agriculture has measured the percent of dry matter content of avocados to determine fruit maturity. The maturity testing process used for the past nine years--the opposing eighths method--was time-consuming and potentially dangerous. It involved the use of sharp blades and required the use of food processor that had to be thoroughly cleaned between each test. Given the steps involved, Inspection Program personnel had to receive significant training to conduct tests.

• Agritourism Manual Helps California Farmers Grow Economically

  A 1999 survey of California farm operators revealed a growing need for materials on two increasingly profitable industries: agritourism and nature tourism. Farmers and ranchers have heretofore lacked a centralized resource for obtaining such materials, in a time when opportunities abound for tourist ventures to take root.

• IPM Programs for Celery, Tomatoes Aid Growers, Public

  North American vegetable growers face a compelling need to reduce pesticide use for several reasons, including the decrease in available and effective pesticides due to the development of resistance in pests and to increasingly restrictive state and federal legislation. AES Professor of Entomology John T. Trumble of UC Riverside has led research on novel, low-input pest management strategies that have greatly reduced the use of toxic class-one and class-two pesticides by California celery and tomato growers.

• Automated Trap Gives Reliable Pest Counts

  Traditional traps used to monitor pink bollworm populations in California cotton fields were unreliable. The numbers caught in traps varied from zero one day to hundreds the next morning. Research indicated that entry into the traps by adult males was influenced greatly by temperatures and wind speed.

• Conservation of Biological Control Posterchild, Cottony Cushion Scale

  The vedalia beetle is a predator of a major citrus pest, cottony cushion scale. However, many of the new insectides developed to replace organophosphates (neonicotinoids and pyrethroids) or developed as reduced-risk alternatives (insect growth regulators) are quite toxic to this beneficial insect. Biological control is important in the control of cottony cushion scale as insecticides are not very effective against the pest.

• New Bait Technology Controls Ants in Urban, Agricultural Environments

  Ants are the major pests in urban environments. Recent introductions of the red imported fire ant in urban environments in California pose a serious threat to agriculture. Argentine and field ants are a major pest in citrus and grapes, where they tend, or care for, homopteran pests and disrupt biological control.

• High-Pressure Washer Removes Red Scale for Citrus Fruits

  California red scale is one of the key pests of citrus in California. This pest can damage and kill citrus trees when it attains very large populations, which is a rare occurrence. The more common economic damage results from these scale insects settling on the fruit, causing cosmetic flaws and a downgrading of the fruit. Significant economic losses from this cosmetic damage occur at much lower population densities than the high densities required to damage the trees. Consequently, there is a very low threshold for California red scale in citrus orchards. To keep populations below the threshold, growers have traditionally relied on high-volume sprays (up to 1,000 gallons per acre) of insecticides.
