Agriculture generates $59 billion and employs nearly 400,000 individuals in California. The industry, however, is often threatened by challenges like climate change, land conversion and water scarcity. Motivated to act, Sustain Southern California – an organization associated with UC Irvine Beall Applied Innovation – hosted a roundtable discussion on Feb. 20 featuring subject matter experts including Darren Haver, director of UC Agriculture and Natural Resources' Research and Extension Center System.

During his keynote address, Jose Arriaga, Orange County Agricultural Commissioner, defined sustainability as food and fiber production that does not compromise the ability for future generations to meet their needs. In doing so, he acknowledged the benefit of discussing such timely topics with key players, especially for places where agriculture is not as prevalent as it used to be. 

“Many people don't think of Orange County as a place for agriculture. It's probably because less land is being reserved for agriculture, not like back in the day. And that worries me,” said Arriaga.

The first roundtable discussion centered on sustainable agriculture, with Haver participating alongside other industry leaders based in Southern California, including A.G. Kawamura of Orange County Produce, Steve Brazeel of Sunterra Produce and Elevated Foods, Anthony Curci of Buttonwood Ranch and Parker Cohn from Performance Resource Management.

In discussing today's generation, Haver said that he has seen a shift over the last few decades away from yield alone, which used to be the most important aspect of production in agriculture. Today, much more attention is dedicated to sustainability – a change that Haver attributes to the younger generation of researchers and plant scientists working in agriculture.

There has also been an emphasis on sustaining the environment while maintaining economic progress. Haver recognized these important elements, but highlighted the social impact of sustainability, too.

“I don't have all the answers, but I do believe that addressing the environmental, economic and social aspects of agriculture is important. I also think that these factors should be addressed systemically rather than in silos,” said Haver.

Southern California agricultural producers, in particular, are responsible for $7.8 billion in gross receipts and nearly 100,000 jobs directly related to agriculture. In Orange County alone, where Haver is based at the South Coast Research and Extension Center, agriculture makes up $86 million of total economic output, with nurseries leading as a top commodity followed by fruit trees, vegetable production and livestock and apiary.

‘Super Carbolicious’ 4-H Food Fiesta challenges young chefs

Sadie, 4-H member of Orange County, begins her presentation in front of two judges. All photos by Saoimanu Sope.

Inside a quiet classroom, Sadie, a 4-H member in Orange County, stands in front of two judges with an insulated cooler bag in hand. From it she pulls out plates, utensils and napkins and sets them down on the table. She unzips the bottom compartment and carefully reaches for a cast iron platter with golden fluffy pancakes piled on top.

“Would you like syrup with your pancakes? I highly recommend it,” said Sadie, an eighth grader who is participating in the annual 4-H Food Fiesta for a second time.

4-H, a youth development program supported by the University of California Agriculture and Natural Resources and administered through local UC Cooperative Extension offices, promotes hands-on experiential learning for all youth.

Rita Jakel, 4-H program coordinator for Orange County, described the Food Fiesta event – intended for ages 5 to 18 – as an opportunity to practice and showcase public speaking skills through a fun, food-related competition.

Youth present their creations before a panel of evaluators, who ask them to describe how they prepared the dish and why, and how they managed challenges throughout the process. The interaction between youth and adult leaders provides a unique opportunity for youth to practice career readiness skills such as job interviews and public speaking.

Kaitlin, 4-H member and first-time participant in the annual Food Fiesta.

This year's theme was “Super Carbolicious” and 4-H participants were encouraged to make their favorite dishes using ingredients like pasta, potatoes and bread. Carbohydrates are often perceived as unhealthy, which is not a helpful mindset to have when teaching youth about nutrition. Carbohydrates provide the body with glucose, which is converted into energy that people need to function throughout the day.

Some of the dishes that were presented during the Food Fiesta included chocolate chip banana bread, cheesy baked potatoes, cookies and Nutella-stuffed crepes. 4-H member Kaitlin had only ever attended the Food Fiesta to cheer on a friend. This year, she decided to participate and presented pumpkin macaroni and cheese as her entry.

“Pumpkin mac and cheese is better than the regular one because there's a lot more flavor and you have to use two cheeses: cheddar and parmesan,” explained Kaitlin, a seventh grader. When asked what motivated her to participate instead of a being a bystander this time around, Kaitlin said that she wanted to work on her presentation skills. 

“Usually, I'm a bit shy and I don't like to share that much. The Food Fiesta helped me practice speaking up more so that I can accomplish my goals,” Kaitlin said.  

Sadie, who loves public speaking, admits that it wasn't always a strength of hers. “There was a time when I hated public speaking. But when I joined 4-H's cake decorating, poultry and food fiesta events, I got more comfortable with public speaking,” she said. “Now, I like going to events and showing off. I get to show off turkeys, my cakes and, today, I presented homemade pancakes.”

Sadie presents her Food Fiesta entry of homemade pancakes.

Helping to keep the day's festivities running smoothly were two 4-H state ambassadors: Michaela and Laurelyn, two high school seniors. Both have been involved in 4-H for over nine years, with Laurelyn being a third-generation 4-H member. “My grandmother grew up in a 4-H club in Orange County. She still raises breeding lambs for 4-H members to this day,” said Laurelyn, whose mother was a 4-H member in San Joaquin County.

As state ambassadors, they are responsible for creating and presenting workshops during state, national and regional events. “We also engage the public via social media, specifically TikTok and Instagram (@4horangeco),” said Michaela, who is in her second year as an ambassador.

During the Food Fiesta, Michaela and Laurelyn made themselves available to answer questions from participants and their families. Both ambassadors agreed that seeing parents involved in 4-H should not come as a surprise. “Being in 4-H is a family effort. This isn't an extra-curricular where you just drop your kids off and leave,” said Michaela.

Laurelyn shared that the biggest misconception others have about 4-H is that they think it's about introducing youth to agriculture or livestock. There's a civic engagement and leadership component to it, too. “If parents knew about all the ways 4-H can benefit their kids, I think more people would want to join us,” she said. “And they're finding fun ways to help us learn life skills, like this Food Fiesta.”

The homemade dishes weren't the only thing to look forward to, however. In another building, Sandy Jacobs, volunteer event coordinator, and her team set up a kitchen quiz for members. On several tables, there were different cooking tools and participants were challenged to name as many tools as they could. 

In another classroom, while some members were presenting food, others presented their themed table setting décor. Participants had to prepare a complete table setting entry including a menu card, centerpiece and table settings for two. Judges considered creativity, use of color, table setting etiquette, knowledge in talking to the judges, and appearance in their evaluation. 

Finally, to wrap up the day, members competed in a cupcake decorating competition. Participants were responsible for bringing their own supplies including tools and edible decorations for Cupcake Wars. Depending on their age group, participants had 20 minutes to decorate two to four cupcakes, each of a different theme.

Food waste, nutrition in prison focus of webinars Feb. 22, 29

Free webinars about food waste and nutrition in correctional systems will be presented by the University of California Agriculture and Natural Resources.

The UC ANR Sustainable Food Systems Emerging Issues Webinar Serieswill first cover food waste on Feb. 22.

“The Sustainable Food Systems strategic initiative panel aimed to highlight innovative solutions to emerging issues within the food system from field-to-fork,” said Danielle Lee, UC Nutrition Policy Institute director of communications and research engagement.

“Over one-third of all available food in the U.S. is uneaten through food loss or waste – totaling up to over $160 billion – which has negative impacts on food security and the climate,” she said. “Households could save over $370 per person each year by reducing or preventing food waste. Additionally, when uneaten food ends up in the landfill, it generates greenhouse gases, and landfills are now the third largest producers of methane in the U.S.”

“California's adoption of SB 1383 aims to solve these problems,” Lee said. “You'll meet experts who are implementing consumer education and organic waste recycling programs aligned with SB 1383.” 

The second 90-minute webinar, on Feb. 29, will focus on nutritious foods for residents of correctional facilities.

“We chose incarcerated people as our case study population for two reasons – the California Department of Corrections and Rehabilitation is the single largest public purchaser of food in the state and studies have shown that 63% of incarcerated individuals rarely or never have fresh vegetables and 55% rarely or never have fresh fruit.”

California has two policies that can support institutional procurement of fresh produce – AB 822 and AB 778.

“The Harvest of the Month program is an innovative solution to implementing these policies while supporting improved nutrition security for incarcerated individuals,” Lee said. “Prison gardening programs can not only provide therapeutic benefits to residents, but also reduce recidivism rates and serve as workforce development opportunities to better prepare residents for returning to their communities post-incarceration.”

  Michael Cohen, UC Cooperative Extension organic materials management and agri-food systems advisor for Santa Clara County
• The opportunities in statewide programs in reducing household food waste: Results from UC ANR household food practice needs assessment
  Yu Meng, UC Cooperative Extension youth, family and community advisor in Riverside, San Bernardino and Imperial counties

Part 2 - Farm to Corrections: Cultivating Justice through Nutrition and Gardening Initiatives

Thursday, Feb. 29, at 10-11:30 a.m. PT

Experts share insights on groundbreaking initiatives for justice-involved individuals' access to California-grown produce and nutrition and gardening education. Innovative initiatives such as a “Harvest of the Month” program by the California Department of Corrections and Rehabilitation in collaboration with the UC Nutrition Policy Institute and Impact Justice aim to increase access to fresh, locally grown fresh fruits and vegetables and trauma-informed nutrition workshops. They also highlight the impact of UC Master Gardener projects on rehabilitation and workforce development.

Agenda:

• Produce during and after prison: Increasing justice-impacted individuals' access to California-grown produce and nutrition education
  Carolyn Chelius, UC ANR Nutrition Policy Institute; Heile Gantan, Impact Justice; Lance Eshelman, California Department of Corrections and Rehabilitations

No-till annual wheat better for soil health in California’s climate

One more reason to adopt sustainable cultivation

California wheat farmers could both maintain their yields and improve soil health by growing annual wheat without tilling the soil year after year.

This could be one more encouragement to farmers to adopt a sustainable practice commonly called conservation tillage, no-till or minimum-till cultivation, impacting how we grow a grain that supplies about 20 percent of the calories and protein for people around the world.

A new study, by a team led by Mark Lundy, University of California Cooperative Extension specialist in UC Davis' Department of Plant Sciences, offers new insight for decades-long discussions around soil conservation, sustainable agriculture and climate-warming emissions related to growing our food. The study has been published in the journal Soil and Tillage Research. For the first time, researchers have shown that annual wheat that is not tilled each year is better for stashing carbon in the soil than perennial wheatgrass, while still yielding more crop in Central California.

Previous studies have looked at annual wheat that is tilled each year, annual wheat that is not tilled, and a cousin species, perennial intermediate wheatgrass (trademarked Kernza), which also is not tilled. But until now, no one has looked at all of the benefits and trade-offs together. Most importantly, “no one has ever controlled for tillage,” Lundy said. “And, no one has compared annual wheat to perennial intermediate wheatgrass over multiple years in a Mediterranean climate, which is what we have in California.”

This study also is unique because it delves into the deeper question of what is going on in the soil that drives the different results for carbon there. Soil carbon reflects various processes linked to plant activity and soil health. Measuring the different forms of soil carbon may also signal whether a farming system is accumulating carbon in the soil over time – a plus for reducing climate-warming gases in the atmosphere.

“Measuring soil carbon is complex and nuanced,” said Kalyn Taylor, the lead author on the paper. “We started this experiment because we wanted to know whether and how plant activity and tilling or not tilling would affect the carbon story belowground in California's climate.”

“When we started this study, we thought the crop being perennial or annual would drive the differences in carbon storage in the soil,” Lundy added. Specifically, they had expected perennial wheatgrass would lead to more carbon in the soil because of its deeper, better-established root system. “But that's not what we found,” he went on. “What we found was, it was the lack of tillage, plus the level of productivity of common annual wheat, that made the difference in soil carbon here in California.”

Soil carbon in annual vs. perennial grain

In 2017, Lundy, then-graduate-student Taylor, UC Davis Professor Emeritus Kate Scow and others on the team started measuring different forms of soil carbon in test plots at Russell Ranch, west of campus. Plots were planted with annual wheat that was tilled each spring, annual wheat that was not tilled and perennial intermediate wheatgrass (Kernza) that also was not tilled.

Each year, the researchers measured the carbon present in the soil, the amount of soil organisms (which have carbon in their bodies) and the amount of material the plants created.

At the end of three growing seasons, they found that land planted with no-till, common, annual wheat had the highest amount of soil organisms, measured as biomass, of the three treatments.

The researchers also found soil carbon is more likely to remain stable in the no-till, annual plots, compared to both tilled wheat and wheatgrass.

In addition, the no-till, annual wheat produced plant material more consistently than the perennial wheatgrass across the three years, which saw variation in rainfall.

“Overall, annual wheat grown without soil disturbance or tillage had both higher productivity and higher potential for storing carbon in the topsoil than perennial wheatgrass in our Mediterranean climate,” Lundy said.

Related research

“No-till annual wheat increases plant productivity, soil microbial biomass, and soil carbon stabilization relative to intermediate wheatgrass in a Mediterranean climate,” is online now and will be published in the January 2024 edition of Soil and Tillage Research.

The team also found that tilled annual wheat vs. Kernza stores total carbon at different depths in the soil profile and hosts distinct soil fungal communities, primarily in the root zone and topsoil: Taylor, K., Samaddar, S., Schmidt, R., Lundy, M. and Scow, K., 2023. Soil carbon storage and compositional responses of soil microbial communities under perennial grain IWG vs. annual wheat. Soil Biology and Biochemistry, p.109111.

Previous work comparing the perennial grain known as intermediate wheatgrass (trademarked Kernza) to annual wheat had not distinguished the extent to which soil health benefits are a function of the perennial nature of the crop. Read the story here.

Rachel Surls has cultivated a healthier LA County through gardens

Rachel Surls, left, shown giving a workshop at a community garden, has been teaching Angelenos how to grow food since 1988. She has relied on UC Master Gardener Program volunteers to help extend information to the community.

UC Cooperative Extension advisor who promotes school gardens, urban agriculture to retire after 35-year career

A stroll through a leafy, green garden can give one temporary relief from life's harshness. During her career, Rachel Surls has used gardens to cultivate healthier communities, whether they are growing nutritious food or providing science lessons for students.

Over the past 35 years, Surls, University of California Cooperative Extension sustainable food systems advisor in Los Angeles County, has witnessed many changes – such as promoting public events on Instagram rather than typing and mailing press releases. A comforting and consistent presence has been the UC Master Gardener Program, part of UC Agriculture and Natural Resources. 

“As I look back, the UC Master Gardener Program has been a constant in my work. It helps so many people,” said Surls, who joined UCCE as a school and community garden coordinator in 1988.

“My new job with UCCE-LA was my dream job. I organized community gardens around the county and supported teachers who wanted to start school gardens,” recalled the Michigan native, who plans to retire at the end of the year. “I had a bachelor's degree in agronomy and was freshly out of a stint with the U.S. Peace Corps in rural Honduras. My work there inspired me to pursue community development work related to gardening.”

Rachel Surls has worked with the UC Master Gardener Program to educate the public about issues such as preventing the spread of citrus diseases from backyards to farms.

Louisa R. Cardenas, trustee of Los Angeles County Natural History Museums, was a UC Master Gardener volunteer for 25 years.

“Among Rachel's many skills and assets are her willingness to listen to and consider ideas from Master Gardeners that eventually reach and empower Los Angeles County residents to grow food that supplements their nutritional needs,” Cardenas said. 

To complement the nascent UC Master Gardener Program in Los Angeles County, Surls organized “Gardening Angels,” a cadre of volunteers to work with teachers and students to develop school gardens. She edited a guide for teachers, parents and volunteers to build gardens for children.

“I met Rachel in 1992 and was so blessed to come up through the ranks with her,” said Rose Hayden-Smith, UCCE emeritus advisor in digital communications in food systems and extension education. “We were in neighboring counties, and had many similar programmatic interests, including school gardens. Her research informed my work and was so helpful to me.”

Advancing food security, community nutrition

In 1994, after earning her master's degree from Cal Poly Pomona in agricultural science with a focus on agricultural education, Surls accepted a newly created position: UC Cooperative Extension urban horticulture advisor.

To retain Los Angeles County funding in 1992, the UCCE staff had become part of the county's Housing Authority/Community Development Commission. As the UCCE urban horticulture advisor, Surls was tasked with developing gardens at five public housing sites. At one of these locations, Carmelitos Housing Development in Long Beach, she worked with community partners to select landscape trees, hire a greenhouse contractor and design a horticulture job training program for public housing residents. This site became known as the Growing Experience Urban Farm.

“I'm pleased that 29 years later, the Growing Experience is still an active community farm where UC Master Gardeners offer workshops for the community,” Surls said. 

In 1997, when George Rendell retired as director of UCCE in Los Angeles County, Surls applied for the job. For the next 14 years, she oversaw more than 70 employees and local programs, including the 4-H youth development program, which launched afterschool, hands-on learning for children. 

Surls, shown visiting an urban farm in San Diego, expanded her scope over her career from school gardens and community gardens to working with urban farmers. She created an urban agriculture website, with resources covering business management, food safety, marketing and regulations.

Surls, who participated in 4-H herself as a child, worked closely with 4-H funders. She helped secure grants, contracts and gifts for 4-H as well as the UC Master Gardener Program and UCCE nutrition programs for projects that encouraged Angelenos to eat more fruits and vegetables.

“Rachel was incredibly creative and innovative as a leader,” said Hayden-Smith, who served as director of UCCE in Ventura County. “Rachel models a kind of quiet leadership that invites people into the process, honors the group and moves work forward in important ways.” 

While working, Surls earned her Ph.D. in higher education administration at Claremont Graduate University in 2008, with an eye on pursuing other leadership roles. Instead, the global financial crisis inspired her return to working directly with Los Angeles County residents on urban gardening to reduce food insecurity.

To focus on outreach, the UCCE sustainable food systems advisor handed her UCCE director duties to Keith Nathaniel, UCCE 4-H advisor, at the end of 2011.

Developing, sharing resources for urban farming and gardens

In 2012, she organized colleagues within UC Agriculture and Natural Resources and community partners to study the needs of urban farmers and begin offering workshops for them. She led the development of an urban agriculture website, with resources covering business management, food safety, marketing and regulations. She served on the leadership board of the Los Angeles Food Policy Council and began advising cities on policies that would make it easier for residents to grow food.

“These have been my favorite and most productive years of my career,” Surls said.

Drawing on skills she began honing as an undergraduate at Virginia Tech as a news writer for the Virginia Extension Service, Surls co-authored a book about the history of agriculture in Los Angeles County, called “From Cows to Concrete: The Rise and Fall of Farming in Los Angeles.” She is currently working on a second book about urban farming in the U.S.

The Grow LA Gardens Initiative – which helps aspiring gardeners start their own gardens quickly – is one source of pride for Surls. Hundreds of people have taken the four-week course and, after participating, nearly 70% planted gardens. 

In 2018, Surls was honored with the Bradford-Rominger award by the Agricultural Sustainability Institute at UC Davis for her work promoting community gardens, school gardens and urban agriculture.

With community gardens and school gardens now commonplace, Surls chuckles as she recalls veteran UCCE colleagues advising her to choose a more “serious” academic focus early in her career.

“It's gratifying to see so many people in academia working on farming in cities, school gardens and community gardens,” Surls said.

In 2012, Surls visited the White House garden while in Washington D.C. to celebrate the U.S. Department of Agriculture's 150th anniversary. She is writing book about urban farming in the U.S.

Advocating for equity

In 2022, while Surls was on sabbatical, she and Cardenas – the longtime UC Master Gardener volunteer – requested and received $100,000 from the Los Angeles County Board of Supervisors to hire an equity, diversity and inclusion coordinator and to fund outreach. This UC Master Gardener project championed by Supervisor Sheila Kuehl specifically reaches underserved populations within the county. “Such a significant achievement would not have been possible without Rachel's encouragement and support,” Cardenas said.

After she retires, Surls plans to volunteer her expertise for online training of UC Master Gardener volunteers statewide. To support their program efforts including outreach to the Spanish-speaking community and scholarships for underserved communities, Surls has pledged to give $5,000 as a matching gift to donations to the UC Master Gardener Program in Los Angeles between Giving Tuesday, Nov. 28, and Dec. 31 at https://ucanr.edu/LAmastergardener.
