REC System Director Haver encourages systemic approach to agriculture
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
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.
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.”
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.”
Part 1 - Harvesting Solutions: A Trio of Perspectives on Addressing Food Waste from Field to Fork
Thursday, Feb 22, at 10-11:30 a.m. PT
To minimize food waste, three experts explore factors influencing food loss and waste, delve into innovative recycling techniques, and explore statewide initiatives targeting household food waste. Experts in postharvest handling, food waste recycling and community education will share research findings and strategies.
Agenda:
- An overview of food waste in fruits and vegetables
Deirdre Holcroft, Holcroft Postharvest Consulting - Exploring means to extract embodied energy and lower greenhouse gas emissions in food waste recycling
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

Recuerdan a los centros de distribución de alimentos sobre la importancia de evaluar sus sistemas de seguridad alimentaria
Los meses de invierno que proceden a las fiestas decembrinas, cuando los centros de distribución de alimentos registran una de las mayores actividades del año, ofrecen una buena oportunidad para que estas empresas realicen una evaluación de sus sistemas y procesos sobre seguridad alimentaria.
Para asistir en ese proceso, expertos en la materia les recuerdan a los administradores de los centros de distribución de alimentos, que el University of California Sustainable Agriculture Research and Education Program (Programa de Investigación y Educación sobre Agricultura Sustentable de la Universidad de California) o UC SAREP por sus siglas en inglés, ofrece un conjunto de recursos sobre seguridad alimentaria – en inglés y español – en su sitio web.
Los recursos educativos de UC SAREP incluyen:
- Una guía paso por paso para los centros de alimentos sobre la forma de llevar a cabo una auditoría de seguridad alimentaria por un organismo externo, con un enfoque en cómo responder a las preguntas de los compradores.
- Dos muestras de planes sencillos cuya intención es servir como punto de partida para ser adaptados a las operaciones y prácticas de cada centro de distribución de alimentos.
- La muestra de un procedimiento operativo estándar o SOP, documentos relacionados a 11 tareas comunes que llevan a cabo los centros de distribución de alimentos.
“Esperamos que estos recursos puedan ser útiles en asistir a los centros de distribución de alimentos a adoptar mejores prácticas y controlar los riesgos relacionados con la seguridad alimentaria”, señaló Gwenael Engelskirchen, coordinador de alimentos y agricultura sustentables de UC SAREP, quien encabezó la creación de estas herramientas educativas.
De acuerdo con los Centros para el Control de Enfermedades, uno de cada seis estadounidenses (o 48 millones de personas) enferma y tres mil mueren anualmente por enfermedades transmitidas por alimentos contaminados. En el 2011, para ayudar a prevenir la incidencia de enfermedades alimentarias, el gobierno federal promulgó la ley Food Safety Modernization Act (FSMA) (Ley para la Modernización de la Seguridad Alimentaria) o FSMA, por sus siglas en inglés, la cual fue diseñada para destacar las acciones tomadas en varios puntos a lo largo de la cadena de suministros de los alimentos para humanos y animales.
Los recursos de seguridad alimentaria para el centro de alimentos de UC SAREP tienen la intención de ayudar a los centros de distribución de alimentos a navegar estar regulaciones sobre seguridad alimentaria y promover mejores prácticas. Estos recursos también están disponibles en español en Recursos de seguridad alimentaria para los centros de distribución de alimentos.
Guía para la certificación en seguridad alimentaria
Algunos compradores verifican el programa de seguridad alimentaria del proveedor requiriendo una auditoría que sea realizada por un organismo de certificación independiente o una compañía auditora. Esta Guía para la Certificación sobre Seguridad Alimentaria ofrece consideraciones importantes antes de decidirse a buscar una auditoría sobre seguridad alimentaria y ayuda a los usuarios a navegar por el proceso de certificación en seguridad alimentaria.
Plan sobre seguridad alimentaria
A los centros de distribución de alimentos que cumplen con el criterio para un pleno cumplimiento de la FSMA's Preventive Controls for Human Food Rule se les requiere contar con un plan de seguridad alimentaria disponible. Y para todos los distribuidores de alimentos, es bueno tener un documento compartido que describa las operaciones de las instalaciones y cómo manejan los riesgos potenciales de contaminación alimentaria. Dos muestras de planes de seguridad alimentaria, proporcionan un punto de partida y pueden ser adaptados a las operaciones de cada centro de distribución.
Procedimientos operativos estándares
Los procedimientos operativos estándares proporcionan instrucciones detalladas paso a paso sobre cómo llevar a cabo tareas operacionales dentro de un centro de distribución de alimentos. Los ejemplos sobre procedimientos operativos estándares cubren temas comunes como el lavado de manos, limpieza de las instalaciones y más, y tienen la intención de ser adaptados las operaciones y prácticas específicas de cada centro de distribución de alimentos.
Jacob Weiss, de Spork Food Hub en Davis, manifestó que “los templetes fueron un buen inicio para que nosotros creáramos la base de nuestro plan de seguridad alimentaria. Nos ayudó a determinar qué necesitábamos (y lo que no necesitábamos) incluir. Creo que los SOP también son muy útiles porque son suficientemente amplios para empezar, pero lo suficientemente flexibles para agregar las prácticas específicas de tu negocio o centro de distribución”.
Para información adicional, visite las páginas web de UC SAREP en Food Safety Resources for Food Hubs o Recursos de seguridad alimentaria para los centros de distribución de alimentos.
Estos recursos y herramientas fueron creados en colaboración con varios socios del proyecto, incluyendo el Departamento de Ciencias y Tecnología de los Alimentos de UC Davis, el Departamento de Salud y Reproducción Poblacional de la Facultad de Veterinaria de UC Davis, el Centro para Medicina de Precisión y Ciencias de Datos de UC Health y la Alianza Comunitaria con Familias Agrícolas.

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.
