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. 

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.

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.

Farmers of color share their contributions, concerns in UC SAREP webinar series

When agricultural advisors came to the Cochiti Pueblo in New Mexico during the 1940s, they lined the irrigation ditches with concrete, in the name of boosting efficiency and productivity. But in single-mindedly focusing on water delivery, they neglected to consider how the previously inefficient seepage sustained nearby fruit trees. 

Their actions, as well-intentioned as they might have been, disrupted the local ecosystem and killed the trees that had fed many generations, according to A-dae Romero-Briones, who identifies as Cochiti and as a member of the Kiowa Tribe.

“In my language, we call the extension agents ‘the people who kill the fruit trees,'” said Romero-Briones, director of the Food and Agriculture Program for the First Nations Development Institute, a nonprofit that serves Tribal communities across the mainland, Alaska and Hawaii.

The historically tense relationship between Indigenous peoples and government-affiliated programs is one of the many complex dynamics discussed in a six-part webinar series, “Racial Equity in Extension,” facilitated by UC Sustainable Agriculture Research and Education Program.

“As extension professionals, we really need to know about the people we want to work with – what are their worldviews and what's the knowledge base that shapes their decisions,” said Sonja Brodt, associate director of UC SAREP, a program of University of California Agriculture and Natural Resources. “And this is especially important to pay attention to when those people are from cultures or segments of society that have a history of being marginalized or oppressed by mainstream society, and because their significant knowledge has often been made invisible.”

Making communities of color in the agricultural sector more visible is a priority for Victor Hernandez, a sociologist and outreach coordinator for the USDA's Natural Resources Conservation Service. Hernandez, who has organized “Growing Together” conferences for Latino and Black farmers, is trying to get more farmers of color to participate in the upcoming 2022 Agricultural Census.

“If we cannot quantify the demographic, we cannot justify the need,” emphasized Hernandez, explaining that his office uses the data to direct resources that advance equity in service, program delivery and distribution of funds.

A legacy of mistrust

At the same time, however, Hernandez also acknowledged the challenges in registering growers of color for the census, conducted by the USDA's National Agricultural Statistics Service. (According to Brodt, USDA's most recent agricultural census, dating to 2017, counts approximately 25,000 producers of color among 128,535 total producers in California.)

“Many of us that are considered socially disadvantaged or historically underserved…a lot of times our peoples come from [nations with] oppressive governments,” Hernandez said. “And so when you come to the United States and you begin to build your life here, to go and engage with the federal government is not the first knee-jerk reaction.”

On top of government mistrust and fears of deportation or detention, other immigrant groups have seen mainstream agriculture – borne by the “Green Revolution” wave across the globe – replace deep-rooted cultural practices, said Kristyn Leach of Namu Farm in Winters.

“It just makes these small farmers distrust our own knowledge, the knowledge that's existed for centuries – before the kind of current iteration of agriculture that we're situated within right now,” said Leach, who works to preserve the agricultural heritage of her Korean ancestors, and facilitates a farmers' collaborative called Second Generation that adapts Asian crop varieties to climate change.

According to Romero-Briones, a collective memory of supplanted culture also lingers in Indigenous communities. In the Cochiti Pueblo, “primarily a subsistence agriculture community” with a long history of corn cultivation, their practices are distinct from those in the mainstream – including regenerative and sustainable agriculture.

“These practices are not really rooted in Indigenous agriculture,” she explained. “They're actually meant to displace Indigenous agriculture and food systems.”

Building relationships takes commitment

Given that legacy of cultural displacement and appropriation, how do extension professionals and other agricultural advisors slowly rebuild trust with communities of color? For Romero-Briones, it begins with a genuine respect for Indigenous practices, and she urges interested people to contact their local tribal historic preservation officer to begin strengthening those connections and understanding – beyond a couple of phone calls.

“As someone who works with Indigenous people all day, even I need to recognize sometimes I have to meet with people up to 12 times before we actually start talking about the work that I initially wanted to talk to them about,” Romero-Briones said.

In a similar vein, Chanowk Yisrael, chief seed starter of Yisrael Family Farms, encouraged listeners to reach out to members of the California Farmer Justice Collaborative – an organization striving for a fair food system while challenging racism and centering farmers of color.

“To use a farm analogy: we've got this ground, which is the farmers of color who have been neglected for a long period of time,” said Yisrael, who has grown his farm in a historically Black neighborhood of Sacramento into a catalyst for social change. “It's not just going to be as simple as just throwing some seeds and things are going to come up; you're going to have to do more – that means you got to get out and do much more than you would do for any other community.”

Investing time in a community is one thing – and backing it up with tangible resources is another. Technical expertise is only the “tip of the iceberg,” Leach said, as historically marginalized groups are also seeking land access and tenure, more affordable cost of living, and access to capital.

“All of those things are actually much bigger burdens to bear for most communities of color than not having the knowledge of how to grow the crops that we want to grow, and not knowing how to be adaptive and nimble in the face of climate change," Leach explained, highlighting California FarmLink as an essential resource. (The “Understanding Disparities in Farmland Ownership” webinar includes a relevant discussion on this subject.)

Bringing diverse voices to the table

Another key is ensuring that farmers and farm workers of color are represented in management and decision-making processes. Samuel Sandoval, a professor in the UC Davis Department of Land, Air and Water Resources and UC Cooperative Extension specialist in water management, develops outreach programs in English and Spanish for everyone from farm workers to the “boss of the boss of the boss.”

Sandoval said there are often gaps of communication between the decision makers and the people, most often Spanish speakers, who implement those measures. He remembers, for example, talking with water resource managers about their plans for a water treatment plant or new irrigation system – and then discovering that the irrigators and farm workers had no idea those discussions are happening.

“It has to be changed,” he said, “because at the end, the person who is going to operate the irrigation system and turn on or off the valves, the person who is looking if there's a leak or not – that's the person who's not being informed, or has not been informed on purpose.”

That exclusion of certain groups can lead to a loss of invaluable knowledge. Leach said there is a real danger in ignoring the wisdom of communities that have contributed so much to the foundation of food systems in California and around the globe.

“These really kind of amazing, sophisticated and elegant agroecological systems that we don't often legitimize through the scientific language and perspectives aren't seen as being really technically proficient – but, in many ways, they're more dynamic and more resilient than the things that we're perpetuating right now,” she said.

As a concrete example, Sandoval said that while extension advisors and specialists conduct studies to remedy a plant disease, farm workers might be developing – separately and in parallel – their own solutions by asking for advice from their social networks via WhatsApp, a phone application.

A reimagining of collaboration, Sandoval said, would include (and compensate) people working in the field for sharing their perspectives – bringing together academics and farmers, integrated pest management experts and pesticide applicators, irrigation specialists and those who do the irrigation.

A need to look within

Concerns about inclusion and validating alternate sources of knowledge apply also to the recruitment process in extension. Leach said that she has seen listings for advisor jobs that would require, at a minimum, a master's degree – which would automatically disqualify her, despite her extensive knowledge of Asian heirloom vegetables.

“When you look at a job description and you see ‘Asian crop specialist,' only required qualification is a master's degree, and then somewhere down the long list of sort of secondary desired, recommended things is some knowledge of Asian crops or communities…you know that just says a lot in terms of what  has weight,” Leach explained.

Before organizations can authentically connect with communities of color, they should prioritize diversity in their own ranks, said Romero-Briones. First Nations Development Institute had to ensure that they had adequate representation across the many Tribes that they serve.

“Before we start looking out, we have to start looking in,” she explained, “and that means we have to hire Indigenous people who know these communities.”

For extension professionals and other members of the agricultural community in California, the UC SAREP webinar series has helped spark that introspection and a meaningful reevaluation of institutional processes and assumptions.

“These discussions have been tremendously illuminating and eye-opening,” Brodt said. “But hearing and learning is just the start – it's incumbent on us, as an organization and as individuals, to take action to ensure that farmers of color and their foodways are truly respected and valued.”

The “Racial Equity in Extension” series is made possible by professional development funds from Western Sustainable Agricultural Research and Education.

New guide shows how elderberry activates hedgerows, ecologically and commercially

A farm-edge hedgerow can be more than a boundary or barrier. When it comprises blue elderberry, it can be a way to integrate biodiversity in an often-simplified agricultural landscape – and connect with a legacy of stewardship and use by California's Native peoples.

A new guide, published by UC Agriculture and Natural Resources, provides detailed instructions and advice for California farmers on growing, harvesting and marketing blue elderberry. It is available as a free download in the UC ANR catalog at https://anrcatalog.ucanr.edu/Details.aspx?itemNo=8709.

“It's the only publication of its kind, that we know of, that focuses on commercial production of a native species from within a hedgerow, which people normally think of as a conservation feature,” said Sonja Brodt, one of the publication's authors and associate director of UC ANR's Sustainable Agriculture Research and Education Program.

In addition to illustrating the plant's many ecological benefits, “Producing Blue Elderberry as a Hedgerow-Based Crop in California” highlights the economic viability of the products made from its flowers, berries and other components.

“Consumer interest in elderberry products is booming,” said Brodt, “and blue elderberry has the potential to meet local needs with a locally adapted species that is climate-resilient, and can be produced in a relatively low-input way that supports – rather than displaces – our native ecosystems.”

The guide incorporates the findings of a UC SAREP project exploring the farm management practices, nutritional content and market potential of elderberry products. And Brodt emphasized that this resource also draws upon the deep knowledge of Indigenous people, as well as best practices of growers such as Katie Fyhrie, formerly of The Cloverleaf Farm in Dixon and another author of the guide.

“We originally got inspiration to do this work from local farmers who are pioneering the use of blue elderberry harvested on their farms, and from Native Americans in California who have long stewarded and utilized blue elderberry for food and other cultural uses,” Brodt explained.

The other publication authors are Gwenael Engelskirchen, sustainable supply chain analyst for UC SAREP; and Katie Uhl, graduate student researcher; and Alyson Mitchell, professor in UC Davis' Department of Food Science and Technology.

Growing elderberries in hedgerows adds to farm income, benefits environment

As the sustainability of agriculture continues to be threatened by changes in climate, pests and loss of biodiversity, the ancient practice of planting hedgerows with edible and medicinal species such as elderberry can help growers generate additional revenue while fostering beneficial insects and improving soil health. 

Most modern-day farmland is occupied by simple “monocrop” systems that often require frequent, energy-intensive inputs like synthetic fertilizers and pesticides to sustain their yields. These practices can be harmful to water quality, biodiversity and soil health.

But farmers who incorporate perennials into their farm landscapes can better harness living things—crop plants, pollinators, beneficial microbes and natural enemies of pests—to provide services rather than adding synthetic products, to the ultimate benefit of the farm and the environment.

Restoring field edges by planting hedgerows is a common way to add perennials to farm fields without taking land out of production. These managed rows of trees, shrubs, grasses and wildflowers were an ancient feature of agricultural landscapes throughout the world. 

 

As farmland industrialized in Europe and North America in the 1900s, many old hedgerows were removed. But hedgerows have seen a resurgence in recent years as their significant environmental benefits—including natural pest control and pollination services, improved soil health and carbon sequestration—are increasingly recognized.

With hedgerows, “the whole farm can be a site of both conservation and profitability,” says Sonja Brodt, deputy director of the University of California Sustainable Agriculture Research & Education Program (UC SAREP). 

Hedgerows can be costly to establish, and this is often the reason farmers choose not to use them. But incorporating a harvestable crop into a hedgerow can be profitable. 

Brodt is leading a collaborative effort with California farmers and UC researchers to develop native western elderberry as a hedgerow cash crop. Blue elderberry (Sambucus nigra ssp. cerulea) is a native subspecies of elderberry that is well-adapted to Mediterranean climates and grows prolifically across California. It is thought to be more heat- and drought-tolerant than the more commercialized North American and European subspecies of elderberry.

“Elderberries have this great potential as a ‘win-win' crop. Farmers harvesting and selling elderberries from their hedgerows can receive a direct income from a farm practice that benefits the local ecosystem,” says Brodt.

Consumer demand for elderberry-based products has skyrocketed in recent years. Blue elderberry has similar antioxidant levels to blueberries and can be processed into products such as jams, syrups, tea mixtures and herbal supplements. 

“We found that two-thirds of surveyed herbal and specialty foods processors and retailers were strongly interested in sourcing California-grown elderberries and couldn't find enough supply to meet their needs” says Gwenaël Engelskirchen of UC SAREP. Farmers who grow blue elderberry can tap into this growing market.

The research team recently completed a field trial in the southern Sacramento Valley to assess the profitability of blue elderberry. They found that elderberry yields from a 1,000-foot, multispecies hedgerow could provide $2,700 to $4,800 in revenue, after harvest and de-stemming costs, in only the second year after hedgerow planting. This revenue helps offset typical hedgerow establishment costs of $3,000 to $4,000, and elderberry revenue is expected to grow over time as the plant yields continue to increase. Value-added processing and specialty products made on-farm could also increase overall profitability. 

While native elderberry hedgerows is a new area of research for the University of California, North America's indigenous people have been harvesting and tending blue elderberry in California for hundreds of years. Many Native persons across the state continue to gather, cultivate and use elderberry. 

Sage LaPena, Nomtipom and Tunai Wintu ethnobotanist and certified medical herbalist, stresses that “elderberry is one of our most important traditional medicines and we've never stopped using it.” Cultivating elderberry for harvest could be one path towards increased food sovereignty for California's Native American tribes.

“There's an important lesson with this work,” said Brodt. “While new technologies are valuable for making agriculture more sustainable, we shouldn't lose sight of ancient practices that have benefited humanity and our landscapes over thousands of years. Hedgerows and other biological solutions are an essential piece of the sustainability puzzle. In addition, we have much to learn about the value of our native species from Native peoples and their traditional practices.”

Organic farming lessons offered online

Farmers who want to learn organic production practices for California specialty crops can now get training at their convenience on their own computers. The organic farming training is designed by the University of California Sustainable Agriculture Research and Education Program, Organic Farming Research Foundation and California Polytechnic State University in San Luis Obispo.

“This course includes information from the latest scientific research conducted by our University of California colleagues across the state, and boils it down into practical information for beginning or transitioning organic farmers of fruit, nuts, vegetables and other specialty crops,” said Sonja Brodt, UC SAREP academic coordinator for agriculture and environment.

The training program contains six learning modules: soil health, weed management, irrigation and water management, insect and mite pest management, disease management, and business management and marketing.

“We were able to draw on the expertise of 22 technical advisors, the majority of them from UC Cooperative Extension, UC campuses and Cal Poly San Luis Obispo, to ensure the scientific accuracy of the information provided,” Brodt said.

The program provides a combination of written content, videos and do-it-yourself exercises that allow students to follow along at their own pace and test their grasp of the knowledge. Farmers may read or view any parts of the course they choose, in any sequence. No certificate or credit is given at completion.

“While it was developed for California specialty crop farmers, the content is based on foundational principles that are relevant to all organic farmers and our hope is that growers across the U.S. find it to be a useful resource,” said Lauren Snyder, OFRF education & research program manager.

The organic farming training is free. To obtain a link to the training, submit a request at https://ofrf.org/beginning-farmer-training-program.

Funding for this online training program was made possible by the U.S. Department of Agriculture's (USDA) Agricultural Marketing Service through grant AM170100XXXXG011. Its contents are solely the responsibility of the authors and do not necessarily represent the official views of the USDA.
