Youth leaders find their photo-voice

This photo, taken by participant Alexa J., shows a hole in the playground. 'It's not safe to go on the playground because you could get hurt. This is about making the playground safer,' she wrote in the photo caption.

An important aspect of positive youth development is engaging youth in meaningful activities, building youth capacity, and helping youth develop leadership skills. As older students on their elementary school campuses, fifth- and sixth-grade student leaders can have a significant role in inspiring peers to make positive and healthy lifestyle choices. Student leaders can also have great impacts on their own families and communities by sharing what they know about nutrition and health in culturally relevant and accessible ways that inspire those around them.

In academic year 2016/17, three school-based 4-H Student Nutrition Advisory Council (SNAC) clubs in Santa Barbara County embarked on a photovoice project using the Children's PowerPlay Campaign Snapshots and Stories curriculum. The 4-H project was co-led by UC CalFresh Nutrition Education and 4-H Youth Development staff in the youth, families, and communities program. The goal of this project was to train student leaders to recognize and identify how their school environments play a significant role in students' personal health decisions. Through this project, fifth and sixth grade student leaders identified, interpreted and advocated for healthy policy or environmental changes within their own schools and communities.

The 11-week photovoice project started with students and project leaders getting to know one another and building trust with icebreakers, energizers and games. The students came together weekly to discuss barriers and opportunities for healthy play, physical activity and healthy food in their schools. Next, students learned to define important terms like “advocacy” and “photovoice.” Through these meetings and discussions students continued to explore what it means to “have a voice” or “a platform to advocate for change” from within their youth perspective.

Over the course of several weeks, students took walking field trips around their school campuses and photographed images of their school environment that they found significant. Although each student took a number of photographs, they each selected one image that was the most significant to them. Each student shared with the rest of their club why that image was significant and how they felt when they looked at it. Students then wrote a short description about their photograph, why they selected that image, what the image meant, and how that meaning was important to them as a student leader and to their school community. The project culminated with the youth sharing their collective voice with other students, school administrators, teachers and parents.

As a result of this 4-H project, the students were exposed to STEM concepts including camera parts and vocabulary, lighting, framing, and computer skills for basic photo editing. They also developed new lenses for viewing their individual health and the health of their school communities. Some students focused on the beauty and health-promoting aspects of their school campus, such as school gardens, trees, flowers, and nature. Some student leaders took action photos of other students participating in healthy play to emphasize how their school campuses provide safe community spaces for physical activity. Other students focused on environmental aspects that could be improved, capturing images of school cafeterias, playgrounds, buildings, and fences to underline how areas could be improved or enhanced. Through the photovoice project, 4-H SNAC leaders met the challenge to identify and express their ideas for promoting health and healthy changes within their schools. No two photographs were alike and the youths gave their own unique perspectives about their school. From school to school these photographs and stories captured different ideas, themes, and styles of photography.

After the months' long project, it was rewarding and humbling to see the student leaders sharing their unique youth perspective. The youths' communities found value in their photographs as well. Images were framed and displayed alongside their interpretative narratives at local school sites, the school district office, the county fair, and other community sites as testaments to youth vision for healthy and thriving school communities. The school district displayed several of these photovoice stories in the halls of the central district building. Three students entered their photos at the Santa Barbara County Fair. This is notable because none of these students had previous experience entering their work at a county fair and they were able to gain wider exposure and recognition for their work. One student won first place and another received an honorable mention in the county-wide youth photography competition.

The UCCE Youth, Families and Communities Program in Santa Barbara County focuses on deepening engagement in nutrition education with youth and families in low-income settings while increasing positive youth development outcomes.This photovoice project was funded through local grant awards from the National 4-H Council in collaboration with Lockheed Martin, and UC CalFresh Nutrition Education Program, which is a joint agreement among the U.S. Department of Agriculture/Food and Nutrition Service (USDA/FNS), the California Department of Social Services (CDSS) CalFresh branch, and the University of California Cooperative Extension (UCCE).

Keeping cows cool with less water and energy

Innovative cooling technologies tested on dairy cows at UC Davis are addressing the long-standing challenge of keeping dairy cows cool in heat-stressed California.

Standard livestock cooling methods, such as fans and sprinkling cows with water, require significant amounts of electricity and water. The new technologies, being tested at UC Davis by the Western Cooling Efficiency Center and the Department of Animal Science, are designed to reduce water by up to 86 percent and electricity by up to 38 percent over conventional methods.

Milk production and heat stress

Milk is the most valued agricultural commodity in California, with $9.4 billion in retail sales in 2014. Roughly one in every five dairy cows in the nation lives in California. In addition to disturbing the cow, heat stress is a major cause of diminished milk production in dairy cows, with annual losses directly related to heat stress exceeding $800 million.

“The process of rumination, where cows ferment their food, produces a lot of heat, as does milk production itself,” said Cassandra Tucker, a professor in the Department of Animal Science who focuses on dairy cattle welfare. “When the outside temperatures also rise, it's a challenge for the animal in how she's going to try to keep cool. This project is trying to reduce the energy and water use associated with that to help both the cows and the dairy producers.”

How it works

The technologies involve two approaches. The first is conduction cooling, where the bedding area is cooled using heat exchange mats placed where cows lie down. To reduce energy consumption, water flowing through the mats is cooled through a novel evaporative chiller called a Sub-Wet Bulb Evaporative Chiller.

The second approach is targeted convection cooling, which uses fabric ducting to direct cool air onto the cows while they lie down and when they eat. The air is cooled using a high-efficiency direct evaporative cooler.

"This is an exciting research opportunity for UC Davis to combine our expertise in engineering with our expertise in animal science,” said Theresa Pistochini, senior engineer at the Western Cooling Efficiency Center. “There is significant potential to apply existing technologies in a novel way to reduce both energy and water used to cool dairy cows. Through this project we aim to design, test and demonstrate an efficient alternative.”

The project is part of a four-year, $1 million grant from the California Energy Commission to help improve water and energy efficiency in California's dairy industry. The data being collected now will help determine which technology the team should use to pilot at a commercial dairy in a future phase of the project.

UC ANR is a natural partner to help bridge California’s digital divide

Even as the digital revolution has changed the world, there are thousands of California residents in rural areas that do not have an internet connection adequate for engaging in modern technology.

With offices in all California counties and several research centers located in remote locations, UC Agriculture and Natural Resources Vice President Glenda Humiston and UC ANR Chief Innovation Officer Gabe Youtsey believe UC ANR is in a position to forge partnerships with government, industry, and other academic organizations to connect rural Californians with high-speed internet.

Youtsey testified at a rural broadband informational hearing in Sacramento on Aug. 28 held by the Assembly Select Committee on Economic Development and Investment in Rural California, chaired by Rep. Anna Caballero (D-Salinas), and the Communications and Conveyance Committee, chaired by Rep. Miguel Santiago (D-Los Angeles.)

In his testimony, Youtsey characterized the presence of UC ANR in California for the lawmakers.

“We are a network, not a place,” he said. “We have more than 1,500 very applied academics; I call them academics with muddy boots because our job is really to turn science into on-the-ground solutions.”

While it is potentially expensive to bring broadband internet connectivity to every resident of California – from the far reaches of Modoc County in the north to remote desert communities near the Mexican border in the south – those communities' lack of high-speed internet is also exacting a high medical, social, and educational cost.

“High-speed connectivity is needed in rural communities not just for entertainment,” Youtsey said. “It's about online education, medical care, banking and businesses. Digital inclusion is an issue of economic justice.”

Youtsey likens the spread of broadband internet to a successful initiative in the 1930s to promote rural electrification in the U.S. The program was managed by the U.S. Rural Electrification Administration, one of the agencies created under the New Deal, President Franklin Roosevelt's sweeping legislation that helped lift the United States out of the Great Depression.

The government's role in “internetification” could be an investment in infrastructure, Youtsey said.

“It is very expensive to bring wired internet connectivity to places where it has never been before,” Youtsey said at the hearing.

At one UC ANR location, the UC Sierra Foothills Research and Extension Center, laying a wired connection was cost prohibitive.

“The internet provider had to beam a signal from Marysville, up to the top of the Sutter Buttes, and then beam 26 miles across the valley to our location. That was about a $150,000 one-time set-up cost. That's just not realistic in many cases,” he said.

Youtsey said UC ANR would like to leverage its remote locations as launch points for public-private partnerships for rural broadband, a plan that dovetails an initiative now being considered by state legislators.

Assembly Member Eduardo Garcia (D-Coachella) has introduced AB 1665, known as the Internet for All Now bill, which aims to ensure social and economic equity for all Californians in the digital age. This bill would approve funding by Dec, 31, 2022, for infrastructure projects that would provide broadband access to no less than 98 percent of California households.

“We support passage of the bill, but we're not going to stand still,” Youtsey said.

A drone flying over sorghum research plots at the Kearney REC collects information on plant height, leaf area and biomass. Working with large data sets, such as this one, requires high-speed internet.

Already, UC ANR is creating partnerships with rural communities to provide shared internet connectivity. One project underway is located at the UC Kearney Agricultural Research and Extension Centernear Parlier, a 15,000-resident community in rural southeast Fresno County that has one of the state's highest percentages of Latinos. After connecting the center with fast one-gigabit speeds, UC ANR is planning to outfit all 330 acres with outdoor wireless coverage to support research and innovation. The next step will be to pilot a public-private partnership with the local community to work with the center and a vendor to share costs and make affordable broadband upgrades for both the residents in the community and UC researchers.

Another project is located at the UC Lindcove Research and Extension Center at the eastern edge of the San Joaquin Valley near Exeter, an agricultural city of 10,000 near the Sierra Nevada foothills.

“We don't have this site lit up yet. We're working hard on beaming a signal from Visalia, 25 miles away,” Youtsey said. “Once we have it here, we're in the heart of the state's citrus region. We're surrounded by commercial citrus farmers who all struggle immensely with getting broadband. We hope to be part of the solution.”

Partnering with produce providers

What's one way to combat food waste, save money, and expand food knowledge? Ask a UC Master Food Preserver.

Or rather, have a group of dedicated volunteers do a hands-on demo at a CSA pick-up location. Tanaka Farms, located in Orange County, did just that. The farm's Community Supported Agriculture program delivers more than 1,600 produce boxes a month to a subscriber base that is highly motivated to prepare and cook food. Educating their customers is a mission of Tanaka Farms CSA as well as a tenet of the UC Master Food Preserver Program.

Working with Patty Nagatoshi, Tanaka Farms CSA program coordinator, UC Master Food Preserver volunteers have already held two workshops for CSA customers. These classes were tailored to preserving the contents of the CSA box, since CSA members often struggle to find a use for every item they receive. Volunteers handed out a list of suggested recipes as a reference after the workshops. These classes are helping customers to maximize their bounty while also cutting down on wasted food.

Additionally, Master Food Preserver volunteers held demonstrations at the farm's Strawberry and Corn Festivals. There they demonstrated dehydrating strawberry fruit leather, making strawberry freezer jam, canning corn relish and making corn broth.

These off-site demos are a prime example of bringing safe, reputable information directly to the public. Preserve today, relish tomorrow!

UC staff led effort to support youth and families during fire emergency

Late in August, the Helena Fire closed six schools in Trinity County and forced 2,000 people out of their homes. Ultimately, 70 houses were destroyed and Gov. Brown issued a state of emergency in the mountain community.

In the midst of the tragedy, UC Cooperative Extension nutrition education specialist Margarita Alvord and program supervisor Janessa Hartmann quickly developed a plan to serve the children they couldn't reach during the school closures and organized activities to support local families. Alvord brought together several organizations, including Human Response Network, First 5 Trinity County, and Weaverville Parks and Recreation District to address the needs of the fire-stricken community.

The agencies developed a plan to provide youth activities, including physical activity, nutrition education, arts and crafts, and games. They served healthy lunches and provided three days of programming at the Local Assistance Center in Weaverville. 

"We received significant positive feedback from parents, teachers and community members, showing Trinity County's strength, resilience and solidarity," Hartmann said. "The staff at UCCE Trinity County seized the opportunity to ensure the students, families, and community displaced during the fires were offered opportunities to learn and have fun in a safe place."
