Investments in farm-to-school program stabilize farms, expand climate-friendly farming practices

California farmers participating in the state's Farm to School Incubator Grant Program are increasing sales of fresh, organic produce, meat and dairy products to local schools.

Small and midsize farms, women and BIPOC farmers especially benefit

A new report reveals that California farmers participating in the state's Farm to School Incubator Grant Program are increasing sales of fresh, local and organic produce, meat and dairy products to schools, according to researchers evaluating program impacts. The report found that 57% of the program's farmers made sales to schools between April and September 2023, representing an average of 33% of their total farm revenues. All food producers funded by the Farm to School Grant Program state that they use or plan to use climate-smart agricultural practices in their operations during the grant period.

Regional infrastructure, staffing, aggregation and distribution are needed to get locally grown food from farms to schools and kids, says study co-author Gail Feenstra.
California has made the largest investment of any state in the country in farm-to-school programs, allocating approximately $100 million from 2020 through 2022. The report, authored by an independent group of researchers from UC Agriculture and Natural Resources, UC Berkeley, Food Insight Group, Berkeley Food Institute, and U.S. Department of Agriculture, shows those investments are beginning to pay off beyond increasing kids' exposure to food education and California-grown fruits and vegetables. 

While existing research shows that kids who engage with farm-to-school programs eat more fruits and vegetables, are more willing to try healthy foods, and even perform better in class, the California farm-to-school evaluation project examines a gap that most farm-to-school research hasn't addressed: how local purchases from schools affect the agricultural sector and the environment.

The report found that the investments are flowing primarily to the farmers the state seeks to support through this program: Of the 50 producer grantees evaluated in this report, 42% are owned by people who identify as Black, Indigenous and People of Color, and 62% are owned by women. Nearly all (94%) are small to midsize operations.

Three producer grantees revealed that the Farm to School Incubator Grant Program funding likely prevented them from going out of business. “This grant … has and will enable us to do things on the farm that would probably take us a decade to do but we'll be able to do that in one or two seasons. So [it] really moves us forward a lot,” noted one farmer.

Beth Katz, a lead researcher and executive director of Food Insight Group, said, “Farmers are expanding their relationships with local school districts, increasing their sales to schools, investing in infrastructure and staff, and forming new relationships with food hubs that can help them with the often complex purchasing requirements unique to school food. While we're still at a very early stage of understanding the impacts of these investments, we're beginning to see patterns emerge.”

A Humboldt County farmer noted that food hubs, which are also supported by the grant program, are critical to their success in accessing the school food market: “[The food hub] is really a huge game changer to be able to make that one drop in town, even though it's an hour away, rather than going to [several school sites] and just making all these little drops. That's been one of the ways that it's very . . .appealing to us as a farm to participate.”

The report also examines the potential for environmental impacts through direct investments in farmers who use climate-friendly farming practices.

Research shows that kids who engage with farm-to-school programs eat more fruits and vegetables, are more willing to try healthy foods, and perform better in class.

“I'm inspired by the potential for the farm-to-school program to support farmers using environmentally beneficial practices like reducing pesticides, planting cover crops and growing organic — and to help farmers expand or adopt these practices. It's essential these farmers have a market for what they grow to see durable environmental benefits,” said Tim Bowles, who is leading the environmental impacts assessment for the evaluation team and is an assistant professor in the Department of Environmental Science, Policy & Management at UC Berkeley and lead faculty director of the Berkeley Food Institute.

“We're also seeing farms actually expand their acreage in order to sell to schools, suggesting this is a desirable market. We're investigating the environmental impacts from these investments, especially for climate,” Bowles said.

As with many new programs aimed at building out long-delayed infrastructure, school food systems improvement demands a deep-rooted approach.

The farm-to-school program supports farmers using environmentally beneficial practices like reducing pesticides, planting cover crops and growing organic.

“The challenges around changing a complex school food system are substantial,” Gail Feenstra, a pioneer in farm-to-school research and co-lead on the project from UC ANR stated. “Decades of research shows the value to children from fresh, locally sourced food. However, what is becoming more clear from this research is that long-term investments in the full farm to school system are crucial. Without regional-level infrastructure, staffing, aggregation and distribution in place to support getting that locally grown food from farms to the schools and kids, we'll have challenges moving the needle.

"Fortunately, the state's strategic and innovative investments in the entire farm to school supply chain – meaning funding for school districts, farmers and also their regional partners, combined with support from CDFA's regional staff – are beginning to address those long-standing challenges.”

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.

Winter season: A time for food safety systems re-evaluation and education for food hubs

The holiday meal season is often a busy time for food hubs – entities that handle the aggregation, distribution and/or marketing of source-identified regional food – as restaurants, retailers and consumers fill their tables and shelves with an abundance of fresh, local products. However, the subsequent winter months can provide a valuable time for reflection and re-evaluation of a food hub's systems and processes. In this spirit, it may be helpful to remind people working at food hubs that University of California Sustainable Agriculture Research and Education Program (UC SAREP)  offers a suite of food-safety resources – in English and in Spanish – on its website. 

Food hubs manage the aggregation and distribution of food products and must adhere to certain food safety standards.
Educational resources include: 

  • A step-by-step guide for food hubs on how to pursue a third-party food safety audit with guidance on how to navigate buyers' questions.
  • Two sample food-safety plans intended as a starting point to be adapted to a food hub's specific operations and practices.
  • Example standard operating procedure, or SOP, documents related to 11 common tasks carried out by food hubs.

“We hope these resources can play a role in helping food hubs to adopt best practices and control risks related to food safety,” says Gwenael Engelskirchen, sustainable food and farming coordinator with UC SAREP,  who led the development of these educational tools. 

According to the Centers for Disease Control and Prevention, approximately, 1 in 6 Americans (or 48 million people) gets sick and 3,000 die of foodborne diseases annually. In 2011, to help prevent the occurrence of foodborne illness, the federal government enacted the Food Safety Modernization Act (FSMA), designed to outline actions to be taken at various points along the supply chain for both human and animal food. 

UC SAREP's Food Safety Resources for Food Hubs are intended to help food hubs navigate these food-safety regulations and accompanying best practices. Resources are also available in Spanish at Recursos de seguridad alimentaria para los centros de distribución de alimentos

Food safety certification guide

Some buyers verify a supplier's food safety program by requiring an audit performed by a third-party certification body or auditing company. This Guide to Food Safety Certification offers key considerations before deciding to pursue a food safety audit and helps users navigate the food safety certification process. 

Food safety plan

Food hubs that meet the criteria for full compliance with FSMA's Preventive Controls for Human Food Rule are required to have a food-safety plan in place. And for all food hubs, having a shared document describing the facility's operations and how potential risks of food contamination are managed is a good idea. Two sample food safety plans, inspired by the operations of food hubs in California, provide a starting point and can be adapted to a hub's own operations. 

Standard operating procedures

Standard operating procedures provide detailed step-by-step instructions for how to carry out operational tasks within a food facility. The standard operating procedure samples cover common topics such as handwashing, facility cleaning and more, and are intended to be adapted to a food hub's specific operations and practices. 

Jacob Weiss from Spork Food Hub in Davis said, “the templates were a great starting place for us to build the framework of our food safety plan. It helped us figure out what we needed to (and didn't) need to include. I think the SOPs are also really useful because they are broad enough to get you started but flexible enough to add the specific practices of your business or hub.”

These resources and tools were developed in collaboration with various project partners, including Department of Food Science and Technology at UC Davis, Department of Population Health and Reproduction at UC Davis School of Veterinary Medicine, Center for Precision Medicine and Data Science at UC Davis Health, and Community Alliance with Family Farmers.

UC awards Brodt $2M to advance soil health, climate-smart farming practices

Regional farms will demonstrate practices such as cover cropping, reduced tillage, compost and mulch use, hedgerow planting, optimized irrigation systems

To accelerate adoption of climate-smart farming practices, the University of California Office of the President has awarded nearly $2 million to a team of UC Cooperative Extension scientists and community partners working on a network of farm demonstration sites. The project will be led by Sonja Brodt, coordinator for agriculture and environment at the UC Sustainable Agriculture Research & Education Program. This UC Agriculture and Natural Resources project is one of 38 funded with $83.1 million allocated to UC by the State of California for climate action research and innovation.

Scaling up soil health and other climate-smart agricultural practices to sequester carbon, increase water and nutrient use efficiency, and improve the resilience of farms to climate-related threats like drought and floods is a core pillar identified in California's Natural and Working Lands Climate Smart Strategy

Sonja Brodt
Climate-smart agriculture is a systems-based approach that requires localized adaptation across the diverse soils, cropping systems, socioeconomic and cultural contexts throughout California.

“Our project will strengthen the nascent California Farm Demonstration Network for on-the-ground, regionally specific demonstration of a range of climate-smart practices,” said Brodt. “Regional farms will demonstrate practices such as cover cropping, reduced tillage, compost and mulch use, hedgerow planting, irrigation system optimization and more.”

The $1,999,524 project will pilot a participatory partnership extension model that allows farmers to learn from their peers to reduce adoption risks and adapt knowledge to an ever-changing environment, increasing the likelihood of farmer success and accelerating long-term uptake of complex, place-specific practices. 

Building on the capacity of local trusted organizations, project collaborators will be organized in a hub-and-spoke network with three regional Farm Demonstration Hubs (Sacramento Valley, North Coast and Central Coast), a pilot Hmong/Mien Demonstration Hub, and a statewide Organic Demonstration Hub.

Collaborators at each hub will be responsible for identifying and nurturing farm demonstration sites, and conducting demonstration trials and farmer-to-farmer outreach activities. Centralized organization and capacity building will be provided by UC SAREP, UC Organic Agriculture Institute, the California Association of Resource Conservation Districts, the Community Alliance with Family Farmers, and the California Farm Demonstration Network Advisory Panel.

In addition to several UC Cooperative Extension advisors and specialists across the state, partners include the UC Hansen Research and Extension Center and the Rodale Institute California Organic Center, both in Ventura County, and the UC Climate Smart Agriculture Program. Eight Resource Conservation Districts will also be involved in leading Farm Demonstration Hubs.

Hope Zabronsky of the UC Climate Smart Agriculture Program shows the importance of soil structure at a cover cropping workshop.

The project will also conduct soil health assessment activities to inform soil health and resilience monitoring protocols in future research and extension efforts. Since many existing soil health metrics were designed for agroecosystems in the Midwest and Eastern U.S., this project aims to lay the groundwork for research to adapt soil health metrics to the arid and Mediterranean climates of California.  

“By utilizing relationships built between demonstration hub managers and demonstration farms across different cropping systems, we will gather quantitative and qualitative soil health data, information about growers' management practices as well as their own perspectives of what they really need to know about their soils in order to better manage for climate resilience and mitigation,” said Brodt.

Ultimately, the project partners aim to establish an enduring on-farm extension and research system that will help thousands of farmers adopt climate-smart practices tailored to their farms.

Other grant-supported projects focus on water access, conservation

The largest of the Climate Action Matching Grants, an $8.2 million investment, supports the development of planning tools to advance sustainable, inclusive and equitable water distribution for California's 39 million people. The project is led by Ted Grantham, a UC Cooperative Extension specialist in the Department of Environmental Science, Policy and Management at UC Berkeley. Kristin Dobbin, UC Cooperative Extension specialist in the Department of Environmental Science, Policy, and Management at UC Berkeley, and Erik Porse, director of the California Institute for Water Resources are collaborating on the project.

Three other projects involving UC ANR researchers received California Climate Action Seed Grants and Matching Grants subawards:

  • Development of a hydrogel that can work as a soil amendment to help small-scale vegetable farms conserve water led by UC San Diego associate professor Shengqiang Cai with Ruth Dahlquist-Willard, UC Cooperative Extension small farms advisor and interim director of UC SAREP; Mallika Nocco, UC Cooperative Extension specialist; and Matthew Gilbert, UC Davis professor of whole plant physiology. $297,979
  • Development of a tool for predicting climate-water variation led by UC Irvine professor Isabella Velicogna with Tapan Pathak, UC Cooperative Extension specialist. $199,531
  • A study of urban stream corridors led by UC Davis professor Gregory Pasternack with Igor Lacan, UC Cooperative Extension environmental horticulture and urban forestry advisor. $33,824
  • A study of how California's housing crisis affects the growth of the wildland urban interface (WUI), where the fringes of development reach into natural areas led by UC Santa Cruz professor Miriam Greenberg, with Barb Satink Wolfson, UCCE fire advisor, Devii Rao, UCCE livestock and natural resources advisor, and the Central Coast Prescribed Burn Association.

Updated 8/31/23 to add the wildland urban interface study.
