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.
“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.

Residents’ water security concerns could spur climate adaptations
Study: Climate impacts widespread across California, fueling worries over water supply
As water system managers across California devise strategies to help secure their water supply, they often face a major obstacle to implementing those measures: a lack of interest or will to act among community members.
“One of the things that the literature has found is that even if water system managers and local decisionmakers are really worried about climate change and water security, a lot of the adaptation strategies that they have in their toolbox actually require support from residents,” said Kristin Dobbin, a UC Cooperative Extension specialist focused on water justice planning and policy.
Because popular support is essential for realizing many water-related adaptations – from changing the rate structure to approving bonds for new infrastructure – Dobbin and her colleagues recently published a paper looking deeper at residents' experiences of, and concern about, climate impacts to household water supply.
Through a drinking water-focused portion of a long-term panel survey administered by California State University, Sacramento, scholars in the Household Water Insecurity Experiences research network had the opportunity to query Californians on how they are experiencing the climate crisis at their taps. Specifically, the researchers sought to analyze respondents' perceptions of future climate risks to water security.
“As a group that studies drinking water access in California, we're often looking at the system level and community level,” said Dobbin, based at the UC Berkeley Department of Environmental Science, Policy and Management. “So it was exciting to dive into the household level and understand what's happening at a more individual level.”
Climate impacts seen ‘up and down the state'
The statewide survey, conducted in spring 2021, elicited 704 responses from the panelists, representing every census region in the state and nearly every county. More than one-third (34%) of respondents said that their water supply had been affected by an extreme weather event in the past five years. Given the timing of the survey, drought was unsurprisingly the most frequently mentioned impact. Importantly, these climate impacts were felt across California.
“There is an inclination to assume that drought and other impacts are a geographically bounded issue, but what we really see is that is not the case,” Dobbin said. “These impacts are happening up and down the state, all the way to the Oregon border.”
Overall, 85% of respondents reported that they were concerned about the long-term reliability of their water supply. Crucially, the study also indicated that residents were making the connection between climate impacts and risks to their future water security.
“The more impacts they reported, the more concerned they were about future supply and reliability,” said study co-author Amanda Fencl, a senior climate scientist with the Union of Concerned Scientists.
Droughts and heat waves, in particular, seem to increase residents' concerns over water supply the most. Dobbin suggests that framing the need for water-security adaptation strategies around those specific weather events could be particularly useful in marshaling community support.
Knowing the level of concern within the community – and understanding the best way to convey the urgency of climate adaptation measures – could be a boon for local managers seeking to gain public backing for more expensive water projects. Such projects might include self-sufficiency measures that reduce reliance on imported water from other parts of the state.
“That could bolster some water managers to have more confidence in using climate change and extreme events as a way to motivate ratepayers to get on board with these bigger investment decisions,” Fencl said.
Study highlights avenues for more research
While flooding barely registered as a climate impact in the 2021 survey results, Dobbin said that the responses would likely be very different today, after atmospheric rivers inundated the state this past winter. Floodwaters can damage water treatment plants – and storms can knock out power to private wells and larger water system treatment and distribution facilities.
In fact, from the 2021 survey, power outages due to utilities' wildfire prevention policies were the climate impact most frequently mentioned in the “other” category, highlighting for researchers the need to consider and plan for the interconnectedness of water and power systems.
“People forget about the interplay between a reliable electric grid and the ability to run water in your house and the ability for water systems to pump and treat water,” Fencl explained. “When we think about disaster response and disaster preparedness, we need to be a bit more holistic.”
The researchers also pointed to significant differences in experiences of climate impacts across gender and racial demographics, with Latino, Asian American Pacific Islander and LGBTQ+ respondents reporting higher rates of impacts. Given the relatively small sample sizes, however, Fencl said there needs to be larger – and more inclusive – surveys to get a clearer picture of those disproportionate impacts.
Even still, Dobbin added that their study serves as a reminder for scholars, water managers and policymakers to re-center community members, in all their diversity, as key players in the push for more effective and sustainable climate adaptation strategies.
“One of the takeaways from the paper is that we can't forget about the role of the public in this conversation – and we can't bypass the public,” Dobbin said. “The bottom line is that most of the adaptations that we have available to us require some level of residential involvement.”
In addition to Dobbin and Fencl, authors of the study, published in the journal Climatic Change, include Gregory Pierce, UCLA Luskin Center for Innovation; Melissa Beresford, San Jose State University; Silvia Gonzalez, UCLA Latino Policy and Politics Institute; and Wendy Jepson, Texas A&M University.

UC Climate Steward: ‘It’s the most fulfilling work’
Climate Stewards course instructor inspires change in Butte County
Growing up in Butte County, Rose Brazil-Few has watched climate change devastate communities and ecosystems in the form of severe drought and deadly wildfire, including the 2018 Camp Fire that swept through Paradise. Through the University of California Climate Stewards program, Brazil-Few is taking action in her home county – and inspiring others to help.
“Seeing the environmental situation firsthand in California, every day I find a reason to work on climate action projects,” she explained. “It's the most fulfilling work that I could possibly be doing right now.”
As a California Climate Action Corps Fellow (a workforce development program affiliated with California Volunteers), Brazil-Few is working at the Butte Environmental Council as community sustainability coordinator. She said the UC Climate Stewards course she completed last fall – administered by the UC California Naturalist program – taught her crucial lessons she applies every day, especially on framing and conveying the climate crisis.
“One of the biggest takeaways is how to communicate about climate change while we're doing climate action work,” she said. “Sometimes you encounter community members who don't necessarily like the term ‘climate change,' but they still believe in cleaning up parks and planting trees for shade – so focusing on positive action will still accomplish your bigger goals.”
Brazil-Few will further amplify those locally rooted solutions and climate stewardship opportunities when she starts teaching her own UC Climate Stewards course this summer, through Butte Environmental Council.
“Rose is the first CCAC fellow to become a certified Climate Stewards course instructor as part of the Pathway to Leadership we co-developed with CCAC,” said Sarah-Mae Nelson, UC Climate Stewards academic coordinator. “This pathway is an opportunity for fellows to continue fostering community and ecosystem resilience in their communities as active Climate Stewards, once their official fellowship has ended.”
Since launching in fall 2020, nearly 500 people have completed the UC Climate Stewards course, which is delivered by 17 partner organizations throughout the state. Nelson noted that, in addition to the CCAC collaboration, UC Climate Stewards is also working with Sustainability Service Corps and SEI (Strategic Energy Innovations) Climate Corps – and looking into bringing the course to other states.
A 2021 graduate of Humboldt State University with a bachelor's degree in environmental studies, Brazil-Few said she appreciates that the UC Climate Stewards course instills a sense of hope and empowerment and possibility.
“I know some people who feel hopeless because there's such a focus on the doom of climate change – when in reality you can find so many programs and people in your local community making positive change,” she said.
In her community, Brazil-Few highlights the partnership efforts between the Butte County Local Food Network and area growers, the Traditional Ecological Knowledge sharing at Verbena Fields in Chico, and the continued growth of the community composting program – among many other projects.
They all illustrate a key point that Brazil-Few will emphasize as she designs her UC Climate Stewards course: a meaningful climate project need not take place at a large scale – action can happen, literally, in one's own backyard.
“It can be easily attainable and accessible,” she said. “And just talking about it with people and getting your community excited is the very first step in creating a series of events that eventually leads to a bigger impact on climate change and positive environmentalism.”
