Delta farm tour gives GFI fellows a broader view of food system

“Eighty percent of waterfowl depend on agriculture for food,” said Dawit Zeleke, second from right, next to Michelle Leinfelder-Miles.
Global Food Initiative student fellows from University of California campuses throughout the state gathered for a springtime field trip in the Central Valley to learn more about the relationships between food, farming and the environment.

The day-long tour, hosted by UC Agriculture and Natural Resources, began at a farm that is maintained to support wildlife in the breezy Sacramento-San Joaquin River delta region. The GFI fellows also viewed a habitat restoration project at LangeTwins Winery then watched freshly harvested cherries being processed at Morada Produce's packing plant. They wrapped up the day with a tour of a demonstration garden and a discussion of nutrition education at the UC Cooperative Extension office in Stockton. 

UC President Janet Napolitano, who, along with UC's 10 chancellors, launched the Global Food Initiative in 2014, met with the 17 fellows for lunch at LangeTwins Winery.

“We started the Global Food Initiative several years ago with the goal of creating a pathway to a sustainable, nutritious food future for the planet. A small, modest goal,” Napolitano said, adding that she is excited to learn about the fellows' projects.

The GFI fellows are working on projects that range from raising awareness about food production to analyzing the effects of climate change on pollination, and from efforts to make soils safe for growing food in urban areas to using food waste to fuel batteries.

UC Merced senior Ever Serna's GFI project is to educate his fellow college students about where food comes from, before it gets to the grocery store.

“The tour gave me a deeper understanding and appreciation about how food is developed and grown,” he said. “I think when I eat vegetables and fruits, I'm going to be more conscious of what I eat now.”

Reid Johnsen, a third-year Ph.D. student in agricultural and resource economics at UC Berkeley, Global Food Initiative fellow for UC ANR, and participant in the Graduate Students in Extension program, is working with UC Cooperative Extension in Sonoma County to study ranchers' preferences for different payment structures for conservation easement to compensate them for the ecosystem services provided by their land.

“To be able to see agriculture in action makes such a difference to me, to see the way the crops are produced and the variety that's out here,” said Johnsen. “The diversity of crops was not something I was aware of before coming on this trip.”

President Napolitano visited with the GFI fellows over lunch.

“I thought it was interesting to see a lot of different agricultural production systems,” said UC Santa Barbara senior and campus GFI ambassador Bryn Daniel, who works with student activists on student food access and housing security issues.

In addition to learning more about food production, the outing gave the fellows an opportunity to network with peers from other campuses.

“That's what I liked about today's meeting, just meeting everybody and getting these fantastic connections,” said Ryan Dowdy, a third-year Ph.D. student at UC Davis who is converting food waste into energy-producing microbial fuel cells.

“I think this program, and especially the fellowship, is really important for young scientists who dive into this really huge subject of global food,” said Claudia Avila, a graduate student at UC Riverside who studies trace metals in urban agricultural soils.

Best kept secret

In welcoming the UC GFI fellows, Glenda Humiston, UC vice president for agriculture and natural resources, said, “I have a feeling a lot of you aren't familiar with our division. As I travel around the state to different campuses, I keep being told that we're the best kept secret, which I personally do not think is a good thing." 

She explained that agricultural research has been part of the University of California since the land-grant institution's beginning in 1868 in Oakland. UC ANR has researchers on the Berkeley, Davis and Riverside campuses and UC Cooperative Extension advisors in the county offices, she said, adding, “Here in California, our advisors have very robust research programs.”

Aaron Lange, left, explains that he planted the elderberry bush to create habitat for the threatened valley elderberry longhorn beetle.

Farms are wildlife habitat

Michelle Leinfelder-Miles, UC Cooperative Extension delta crops advisor, and Brenna Aegerter, UCCE farm advisor in San Joaquin County, gave the fellows an overview of delta agriculture. Dawit Zeleke, associate director of conservation farms and ranches for The Nature Conservancy, explained why he farms 9,200 acres of corn, triticale, potatoes, alfalfa and irrigated pasture to enhance foraging habitat for sandhill cranes and other wildlife on Staten Island. The Nature Conservancy partners with UC Cooperative Extension along with the U.S. Fish and Wildlife Service, the U.S. Geological Survey, California Department of Water Resources, Oregon State University, UC Merced and UC Davis to study the relationships between agriculture and natural resources.

The Pacific Flyway for migrating birds passes over the delta. “Eighty percent of waterfowl depend on agriculture for food,” Zeleke said. After wheat harvest, they flood the fields. “You should see it in September, October, November and December. Thousands of birds, ten thousand cranes use this place for habitat.”

Randy Lange, on right, said, "We reuse our water as much as possible." Waste water from the winery is captured and used to irrigate vineyards.

Lodi region is zin-ful

En route to lunch, Paul Verdegaal, UC Cooperative Extension viticulture advisor for San Joaquin County, described the Lodi region's wine industry. There are about 750 growers, many of which are small family operations. While 10 to 15 acres used to be typical vineyard size, most have 100 acres to be sustainable and one family member works at an outside job. 

“Agriculture is a tough job and there is no guaranteed income,” Verdegaal said.

About 40 percent of the zinfandel in California is grown in the Lodi region, but there are several wine grape varieties planted. 

Pointing out the bus window to a vineyard interplanted with a crimson clover cover crop, Verdegaal said, “We do see interest in using as few chemicals as possible and using techniques of the integrated pest management program.”

After eating lunch at LangeTwins Winery in Acampo, the GFI fellows took a tour of the winery with the fourth- and fifth-generation owners, Randy Lange and Aaron Lange. The Langes are founding members of the Lodi Rules Program, which helps growers produce grapes and wines in a manner that is environmentally respectful, socially sensitive and economically sound. They pointed out an array of solar panels covering the grape press room that provide electricity. The Langes are planting native plants around the winery to reduce sedimentation, improve water quality and restore wildlife habitat along the Mokelumne River.

The cluster cutter gently separates the cherry clusters into individual cherries.

Bing is king of cherries

When the GFI fellows visited at the end of April, sweet cherry harvest had just begun in Bakersfield area orchards, and cherries were being packed and shipped in San Joaquin County.

“Hemmed in by rain to the north and heat to the south, cherry season is only eight to 10 weeks long,” said Joe Grant, emeritus UC Cooperative Extension farm advisor for San Joaquin County.

“While the Bing variety is still the mainstay of the California cherry industry because of its excellent eating and shipping quality,” said Grant, “acreage of other high quality and earlier-maturing varieties has increased in recent years to lengthen the harvest season. But Bing is still king.” Asked about the effects of climate change on cherries, Grant explained that warmer temperatures are reducing the number of winter chilling hours, which cherries need.

Morada Produce uses waste water from the cherry processing plant to water these walnut trees, said Scott Brown, fifth from left.

The fellows saw the hand-picked fruit being processed for packing at Morada Produce, a family farm in Linden that also grows walnuts, peppers and onions.

“Keeping produce cold is key to maintaining quality,” said Scott Brown, Morada's production manager, as the fellows watched fresh, cold water rain down onto the freshly picked sweet cherries. The leaves and stems floating to the top were removed as the red clusters glided in the water to the cluster cutter, which gently separated the clusters into individual cherries.  Gently conveyed through the plant in flowing water, the cherries were sorted by size and quality at the highly mechanized facility. Air ejectors spit out rejected fruit, so only 70 percent makes it into a packed box. 

“Fruit picked on Monday is packed Tuesday, then shipped to Korea, Japan, Australia and other export markets to be eaten by Friday,” Brown said.

The fellows were fascinated to see the steps taken to ensure high-quality cherries are cooled, sorted and packaged for shipping to stores and consumers. 

“It was just so much more complicated than I knew,” said Jess Gambel, a third-year Ph.D. student at UC San Diego who is studying the effects of climate change on bee pollination in squash plants.

UC Berkeley graduate student Sarick Matzen reads about the brightly colored plants in the demonstration garden that attract bees, butterflies and other pollinators.

Sustainable gardening

As the bus drove past almond orchards, Brent Holtz, UC Cooperative Extension director and farm advisor in San Joaquin County, described his orchard project studying the effects of removing almond orchards by grinding whole trees and incorporating them into the soil before replanting.

The tour wrapped up at the UC Cooperative Extension office in Stockton, with a discussion about how UC CalFresh and the Expanded Food and Nutrition Education Program help low-income Californians attain adequate nutrition and food security, followed by a tour of the demonstration garden maintained by the UC Master Gardener Program volunteers.

“There are more pollutants in urban runoff than in ag runoff,” said Karrie Reid, UC Cooperative Extension landscape horticulture advisor in San Joaquin County. Reid described how she and the UC Master Gardeners work with home and community gardeners to reduce pesticide and water use, and noted that a Water Use Classification of Landscape Species plant list, based on UC research, is available to help gardeners choose landscape plants.

“As a soil scientist, I really appreciated the recurring emphasis on soils as the foundation for agriculture,” said a fourth-year Ph.D. student at UC Berkeley and GFI fellow with Lawrence Berkeley National Laboratory. “From talking with The Nature Conservancy farm operator about how they were conserving carbon in those soils and doing wetlands management to hearing about special properties of the sandy loam soil in this part of the county, and talking with the Master Gardener folks about soil contamination issues.”                      

This is the third class of GFI student fellows. The undergraduate and graduate student fellows, representing all 10 UC campuses plus UC Agriculture and Natural Resources and Lawrence Berkeley National Laboratory, have helped further UC's Global Food Initiative efforts to sustainably and nutritiously feed the world's growing population by working on food-related projects and raising awareness of this critical issue.

UC ANR introduces Market-based Adjustment Plan for staff salaries

Attracting and retaining highly qualified employees is a top priority for UC ANR. To be more competitive among many diverse employment markets, UC ANR leadership has developed a plan to address the competitiveness of our staff salaries. 

As part of UC ANR's overall compensation strategy, VP Humiston approved a four-year Market-based Adjustment Plan for non-represented staff to ensure salaries of existing staff are better aligned with the labor market. All non-represented staff are eligible to participate in this plan, regardless of their position's funding source. For some whose compensation has fallen behind market rates, the Division is making a significant effort to address this issue, as long as it is fiscally viable and prudent to do so.

Using UC Career Tracks, UC ANR Human Resources will be able to identify, review and address the salaries of non-represented staff members whose pay is not in the targeted competitive zone. This strategy will be implemented over four years, which will allow us to better manage the fiscal impact of the salary adjustments.

Eligible employees will be notified individually within the next few weeks. These market-based adjustments are separate and distinct from any merit program approved centrally by President Napolitano.

UC ANR to boost 4-H and MFP county support, better integrate YFC programs

The extended vacancy of the Youth, Families and Communities Director position (vacant 17 months) has given UC ANR leadership time to  consider program needs and how the Division can best meet those needs moving forward. After reflection, collecting recommendations from the respective Statewide Directors and gathering input from the broader ANR community, AVP Wendy Powers has decided not to fill the YFC director position.

“Interim co-directors Shannon Horrillo and Katie Panarella have provided excellent leadership and afforded the Division an opportunity to invest the unused salary provision to further strengthen and support the YFC program,” Powers said. 

Funds designated for the YFC director position will be reinvested into YFC programs to support growth and new opportunities. The statewide program directors identified program integration among 4-H Youth Development; Nutrition, Family and Consumer Sciences; Master Food Preserver and Master Gardener programs as a key priority.

“In support of their vision, we will hire a Program Integration Coordinator that will support efforts to integrate across programs and disciplines to maximize extension efforts and identify new multidisciplinary funding opportunities,” Powers said. “This is consistent with the original intent of having a YFC program and a goal within the UC ANR strategic plan to better integrate and focus our efforts.” The position will be released in the coming months with interviews anticipated in May.

“Subsequently, based on the directors' recommendations, we will invest in hiring a Master Food Preserver and Food Entrepreneurship Academic Coordinator,” Powers said. “This position will bring together our existing work with home food preservation, cottage foods and innovation in agriculture to best address the food security needs of California and to pursue funding opportunities to implement programming.

She also announced plans to hire a part-time 4-H online data system administrator to centralize some 4-H online administrative functions at the state level, reducing the administrative workload on 4-H county-based staff and increasing technical assistance and support.

“We believe this plan will provide the needed support to position YFC for growth and to meet future needs,” said Powers.

Shannon Horrillo will continue permanently as the statewide 4-H director and Katie Panarella as the statewide Nutrition, Family and Consumer Sciences director and co-director of the Master Food Preserver Program. They will continue working in partnership with Missy Gable, the statewide Master Gardener director and co-director of the Master Food Preserver Program to lead these high-priority ANR statewide programs and integration in ways that leverage their assets for greater collective impact.

Karina Diaz Rios
Díaz Rios to co-lead Blum Center at UC Merced

UC Merced is relaunching its branch of the Blum Center for Developing Economies with a focus on food security for the first two years of the faculty-led effort. Karina Díaz Rios, a UC Cooperative Extension nutrition specialist, and Kurt Schnier, economics professor  with the School of Social Sciences, Humanities and Arts, will lead the rejuvenated Blum Center, with administrative help from the Health Sciences Research Institute.

They hope to make the Blum Center a hub for all food-security-related research and outreach on and off campus.

“We want to create a community on campus to address issues of food security,” Schnier said. “We want to help engage students, faculty members and the community to have a direct effect on people's lives.”

Plans include bringing speakers to the campus and community; supporting efforts such as the campus food bank, which serves students and others who don't always have enough food; helping support student researchers such as the students who serve as Global Food Initiative fellows; and facilitating — including through small grants — faculty research centered on food-related topics such as diabetes, communicating about food, and food and social justice issues.

“We're hoping to help translate research into projects that are relevant to the community,” Díaz Rios said.

Merced County's economy is largely based around agriculture, yet many residents do not have adequate access to food or information to help them make healthy choices.

Alec Gerry
Multistate fly project receives national award

Alec Gerry, UC Cooperative Extension specialist in the Department of Entomology at UC Riverside, is part of a research team honored with the 2016 Experiment Station Section Award for Excellence in Multistate Research. The award, given by USDA National Institute of Food and Agriculture (NIFA), Cooperative Extension System and the Association of Public and Land-Grant Universities (APLU), honors the team for “S-1060: Fly Management in Animal Agriculture Systems and Impacts on Animal Health and Food Safety.”

Flies are serious pests of livestock and poultry. House fly, stable fly and horn fly species are responsible for damage and control costs that reach over $2 billion each year in the United States.

Through this project, the scientists developed new chemical, biological and microbial control methods, such as using adult flies to deliver pyriproxyfen, which disrupts insect growth, to sites where larvae are developing. A new fly trap for controlling horn flies removed between 1.3 and 2.5 million flies from a herd of 150 pastured dairy cows. The trap doesn't use insecticide and costs $1.50 less per cow than traditional chemical-based treatments.

Through research and outreach, they have given producers the information and tools needed to select appropriate control methods and apply them in a timely manner. Studies have shown what kinds of weather events and landscape features support fly population growth, and national surveys have shown where insecticide resistance is present. Effective fly management practices result in increased profits, a higher quality of life for animals, a safer food supply and improved quality of life in residential and recreational areas near animal facilities. Adoption of new non-chemical control methods significantly reduces the use of expensive insecticides, cutting costs for livestock producers and reducing harm to the environment.

Gerry shares the award with colleagues at Auburn University, Cornell University, Kansas State University, Louisiana State University, New Mexico State University, North Carolina State University, the Ohio State University, Oklahoma State University, Texas A&M AgriLife, University of Arkansas, University of Florida, University of Georgia, University of Illinois, University of Massachusetts, University of Minnesota, University of Nebraska-Lincoln, University of Tennessee, USDA-ARS, Washington State University, Central Garden and Pet Co. in Walnut Creek, Calif., and Agriculture and Agri-Foods Canada. The project is supported in part by USDA NIFA.

APLU recognizes one multistate project each year for high scientific quality, the level of collaboration and the professional leadership shown in conducting the project. 

A plaque and a small monetary award of $15,000 to support the research project were awarded to the group by the Experiment Station directors on Nov. 14, 2016, at the annual APLU meeting.

DPR honors Virginia creeper IPM team

UC Cooperative Extension,winegrape growers, the Lake County Wine Grape Commission and the Mendocino County Farm Bureau were awarded a 2016IPM Achievement Award by the California Department of Pesticide Regulation for their leadership in protecting crops from Virginia creeper leafhopper.

In 2011, the tiny insect showed up in Mendocino and Lake counties, causing severe losses of wine grapes. By 2014, the new leafhopper had spread across thousands of acres and was devastating vineyards. Some organic growers began using conventional pesticides to stay in business.

Glenn McGourty, UC Cooperative Extension advisor for Mendocino and Lake counties, Houston Wilson, postdoctoral researcher in the Department of Environmental Science, Policy and Management (ESPM) at UC Berkeley, Lucia Varela, UC IPM advisor for the North Coast, Ryan Keiffer, UCCE agricultural technician in Mendocino, Kent Daane, UCCE specialist based in ESPM  and located at Kearney Research and Extension Center, and Serguei Triapitsyn, principal museum scientist at UC Riverside, have contributed to the efforts.

UCCE, grower-collaborators, pest control advisers, the Lake County Wine Grape Commission and the Mendocino County Farm Bureau collaborated to provide newsletters, videos and field days to teach growers to recognize the new leafhopper and its natural enemy, a tiny parasitic wasp that lays its eggs in leafhopper eggs. However, the plentiful natural enemies weren't adequately doing their job in Mendocino and Lake counties. Researchers brought in a new, effective strain of the wasps from the Sacramento Valley, which are now reproducing quickly on their host in the lab and are becoming established in the counties. Eventually, the wasp will enable both conventional and organic growers to reduce synthetic pesticides used to combat the new leafhopper.

The 2016 Achievement Awards were presented at a ceremony at the California Environmental Protection Agency headquarters on Jan. 26 in Sacramento.
