A Note from Our Director | January 2026

Posted in InformationalTagged Leave a comment

As we step into 2026, I want to take a moment to reflect on our progress in 2025 and share what lies ahead for OARS in the coming year. At OARS, we remain committed to building a sustainable and thriving future for California’s farmers and ranchers. Shifts in climate and the environment continue to challenge producers to adapt and innovate. In the last year, sharp changes in the costs of doing business, regulations and markets have layered additional challenges.  

The resilience of our state’s producers is impressive and I’ve enjoyed every opportunity I’ve had to visit farms and ranches and learn not only how producers are adapting to the present moment, but how they are preparing the ground for the next generation. It is our privilege in OARS to advanced science-driven solutions and strengthen partnerships to help producers navigate these challenges and plan for the future.  

Key Highlights: 

Looking ahead, 2026 marks an exciting new chapter. Thanks to the passage of Proposition 4, the $10 billion Climate Bond approved by voters in November 2024, CDFA received critical new funding to expand climate-smart agriculture: $40 million for the State Water Efficiency Enhancement Program (SWEEP), $65 million for soil health and carbon sequestration practices that we will use to support the Healthy Soils Program (HSP), and $15 million to launch a new Equipment Sharing Program (ESP). 

We are pleased to share that public comment is now open on the draft Application for Guidelines and Grant Award Procedures for both HSP and SWEEP.  Your feedback during this public comment period is essential as we refine these programs and prepare to launch the next round of climate-smart investments.  Visit our Climate Bond Funding for Climate Smart Agriculture webpage for more information.

I’m grateful for your continued dedication, and I look forward to the work we will do together to build a stronger, more resilient agricultural system for generations to come. 

With Gratitude,
Dr. Tawny Mata

Update on Cannabis Appellations Program 

Posted in InformationalTagged Leave a comment

OARS has been working on the preparation of a rulemaking to make amendments to the Cannabis Appellations of Origin program (CAP). The CAP was established through voter-initiative with the passage of Proposition 64 in 2016 and CDFA is responsible for establishing the rules for participation in the program and administration of the program. An appellation of origin legally defines products and production methods of specified geographic regions, protecting them from false or misleading labelling and marketing.  

CDFA’s CAP incorporates aspects and traits of various established appellation programs for agricultural products throughout the world, like wine, and applies them to the context of the California cannabis industry. The program will only be available to licensed outdoor cannabis cultivators. Cultivators must submit a petition in accordance with regulations to establish an appellation of origin. This program will promote regional cannabis products and local businesses, prevent the misrepresentation of a cannabis product’s origin, and support consumer confidence about a cannabis product’s origin and characteristics.     

CDFA released the latest rulemaking on January 2, 2026. A 45-day public comment period will run until midnight on February 17, 2026. The proposed changes reduce the number of cultivators per appellation of origin petition from 3 to 1 and provide clarity on the usage of names in conflict with an approved appellation of origin. To learn more about the program, the open rulemaking, and how to comment, please visit the program’s webpage at cdfa.ca.gov/oars/cap. 

As the rulemaking proceeds, we look forward to updating stakeholders and the public on the program’s opening, currently expected for summer 2026. For questions, please contact the program directly at CannabisAg@cdfa.ca.gov 

Stakeholders provide input on draft of the Climate Resilience Strategy for CA Agriculture 

Posted in InformationalLeave a comment

Over the last year and a half, CDFA has been hard at work on our first ever Climate Resilience Strategy for California Agriculture (RSA) led by Deputy Secretary for Climate and Working Lands Virginia Jameson. The RSA lays out the climate change challenges affecting our agricultural system and what the state is already doing—including investing in tools and innovations, developing and administering programs, offering technical assistance—and highlights where there are opportunities for the state to do more.  

State agency staff, including staff from the Office of Agriculture Resilience and Sustainability (OARS), utilized their expertise in agriculture and climate impacts to prepare a draft of the RSA for public comment that was available October 7, 2025 – November 21, 2025. CDFA received 30 letters by email and more than 250 comments through the online commenting system. CDFA is very grateful to all of you who took the time to provide thoughtful and detailed comments. 

Generally, stakeholders were supportive of the RSA and were happy to see its comprehensive approach. Many commenters offered support for existing OARS Climate- Smart Agriculture programs. Below are a few of the common themes we saw in the comments: 

  • Stakeholder interest in a focus on regulatory streamlining and improved state agency collaboration
  • A need for tools to improve fertilizer use and nutrient management  
  • An interest in pursuing California’s energy and farmland conservation goals simultaneously through solutions like agrivoltaics 
  • Revisions on the discussion of voluntary carbon and ecosystem service markets 
  • The development of metrics to track progress on climate action in agriculture 
  • Recognizing the impacts on and the importance of targeted resources for small and diversified farms  
  • The need for on-farm technological advancements and equitable access  

OARS Staff are collaborating with other state agency staff to review and address comments to refine the RSA and uplift stakeholder suggestions where possible. We expect the final RSA to be available in 2026 – check out the RSA website for more updates and information. Stay tuned! 

The Strategy is organized into three pillars that describe CDFA’s plan for climate resiliency.
Within each pillar, the chapters detail agricultural topics important to the pillar’s objective.

Catch Up: The Latest Dairy Methane Reduction Investments 

Posted in InformationalTagged , 4 Comments

In case you missed it, three of the manure methane reduction grant programs administered by CDFA OARS announced awards in December 2025, closing out the year with some exciting news. The awarded projects represent important progress in the dairy and livestock sector towards meeting the State’s methane reduction targets and expands the overall impact of these incentive programs. Including the newest awards, projects supported by the three programs to date will reduce an estimated 27.43 million metric tons of carbon dioxide equivalents over their minimum projected lifetimes. 

California dairy cows and the environment can benefit from improved manure management projects.

AMMP and DDRDP:  

In the fall of 2025, the Alternative Manure Management Program (AMMP) and the Dairy Digester Research and Development Program (DDRDP) received $7 million in Greenhouse Gas Reduction Funds as part of an amendment to the Budget Act of 2025 – these funds were part of a previous appropriation split across two fiscal years. The arrival of the $7 million allowed the two programs to offer some additional awards to those that had applied in the most recent grant round but had not yet received an award due to insufficient funds, boosting the total number of projects captured by the 2024 AMMP and 2024 DDRDP solicitations. 

In December 2025, the AMMP announced the addition of 5 new projects, receiving $3.69 million in grant funds, to the 25 projects originally awarded in April 2025. The DDRDP added 2 new projects, receiving $2.6 million, to its list of 5 originally awarded projects.  

Dairy Plus Program: 

The Dairy Plus Program is a collaborative effort between CDFA and the California Dairy Research Foundation, funded by the USDA Advancing Markets for Producers initiative. Just before the end of 2025, DPP announced awards for its second grant solicitation round. The program awarded 23 projects associated with newly awarded, in-progress, or previously completed AMMP or DDRDP projects a total of nearly $27 million in federal grant funding, matched by more than $28 million from private sources and state Greenhouse Gas Reduction Funds. 

Despite a lengthy delay due to federal transitions, the awards were highly anticipated as these projects install advanced, larger scale manure management practices. These practices not only reduce greenhouse gas emissions but also help manage nitrogen and salt surplus, improving water quality and making great strides in dairy sustainability. 

Stay up to date on methane reduction program news, including the next call for applications for the Dairy Plus Program expected in early 2026 – visit our webpages or follow us on social media! 

A Note from Our Director | August 2025

Posted in InformationalTagged , , 4 Comments

Dear Stakeholders, 

I hope you enjoy this newsletter showcasing the accomplishments of our grantees and partners and giving you a peek at how we lead our programs to serve producers while contributing to the state’s sustainability goals. Additionally, I want to take this opportunity to summarize the funding status of OARS programs, so you know which opportunities are in the future. 

OARS expects to receive $65M in funding for our Healthy Soils Block Grant Program (HSP) and $40M in funding for our State Water Efficiency Enhancement Block Grant Program (SWEEP) from Proposition 4 – Climate Bond and we tentatively plan to offer all of that funding as part of one funding opportunity in fall 2025. Through Prop 4, OARS also expects to receive $15M for a new Equipment Sharing Program (ESP) that will require extensive stakeholder consultation before opening for applications in 2026. The legislature has not appropriated the Prop 4 funding, and the state is still in the process of finalizing rules and guidelines for using the funding. The timeline of these two key external processes may affect OARS’ timeline.  

All state funding appropriations have an “expiration date,” and it is always our goal to give grantees a generous grant term within that expiration date to allow for bumps in the road. To that end, we will keep pushing forward with refining framework for the HSP and SWEEP solicitations at our August 15th Environmental Farming Act Science Advisory Panel (EFASAP) meeting, followed by a written public comment period and simultaneous stakeholder workshops that will inform the final Request for Grant Applications. We look forward to your participation and help refining our block grant model. 

Our Dairy Plus Program, which is a subaward from the California Dairy Research Foundation of a grant funded by the USDA Alternative Markets for Producers initiative (formerly the Partnership for Climate Smart Commodities program), is ongoing but undergoing federal review and revision. This program funds infrastructure on dairies that reduces greenhouse gases and improves nutrient management, and we have approximately $58M remaining in the budget for new grants to producers. We are hopeful that we will be able to announce the results of the 2024 solicitation and run a new solicitation soon, pending a final and functioning grant agreement. At this time, there is no additional funding for the Alternative Manure Management Program and Dairy Digester Research and Development Program. 

Lastly, the Office of Pesticide Consultation and Analysis received a $1.5 million increase in spending authority and an increase in the amount of agricultural mill fee the office can use. Using reserve funding first, OPCA will use the spending authority to address increased research costs, meet the Program activities identified in the Sustainable Pest Management (SPM) Roadmap, and perform increased consultative work for the Department of Pesticide Regulation (DPR), as required by Assembly Bill (AB) 2113 (Chapter 60, Statutes of 2024). In the short term, the increase will also go towards funding our Biologically Integrated Farming System (BIFS) grant program at $1-3 million a year and support for the California IR-4 Project. As AB 2113 related work increases, OPCA will increase spending on research awards related to regulatory work and decrease BIFS Funding. 

We will be in contact with you through our mailing list with all updates related to our grant programs. If you know organizations who are likely to be good applicants or partners for these programs, particularly those that serve socially disadvantaged and underserved producers, please encourage them to sign up for our mailing list and reach out to us directly for more information.  

May the rest of your summer be full of delicious in-season California berries, stone fruit, and tomatoes. I know I’ve been doing my part to support that part of our agricultural economy. 

Sincerely, 

Dr. Tawny Mata

Supporting Spanish-Speaking Farmers in Monterey County with Training on Water Use Efficiency

Posted in InformationalTagged , Leave a comment

The California Department of Food and Agriculture (CDFA), through its Office of Agricultural Resilience and Sustainability (OARS), is helping California farmers grow more sustainably through the Water Efficiency Technical Assistance (WETA) program. This initiative funds local organizations to deliver critical on-the-ground support in three main areas: 

Conducting distribution uniformity (DU) testing for irrigation systems, 

  • Facilitating pump efficiency tests to assess irrigation pump performance, and 
  • Developing and delivering training focused on water and nutrient management. 

One standout example of this work is happening in Monterey County, where the Resource Conservation District of Monterey County (RCD MC) applied for and received WETA funding in 2022. As part of their proposal, RCD MC made a strategic choice to create educational resources for Spanish-speaking farmers and ranchers—a group that comprises nearly a quarter of all agricultural producers in the county, according to the 2022 USDA Census of Agriculture. The goal: ensure more farmers understand how to optimize water and nutrient use—two critical elements of sustainable, cost-effective farming. 

One key resource developed under this initiative is a series of Spanish language training videos created to share knowledge on optimal water and nutrient management  techniques, promoting farmer-to-farmer learning. In this video, Celsa Ortega, the owner of Induchucuiti Farms and a graduate of the Agriculture and Land-Based Training Association (ALBA), discusses her use of low-pressure, uniform drip irrigation systems and underscores the importance of maintaining high distribution uniformity across a field. Celsa’s real-world experience and insights into effective water use reinforce how small improvements can lead to big savings in water, energy, and overall efficiency. 

The video, along with other training materials and assistance supported by the WETA grant, serves as a powerful tool to help growers: 

  • Identify inefficiencies in irrigation systems, 
  • And take action to improve system performance. 

Without WETA funding, these services—including DU and pump testing—would likely have required out-of-pocket expenses from farmers or gone unperformed entirely, leading to unnecessary water and energy waste. By offering this assistance at no cost to the grower, RCD of Monterey County is helping farms become more resilient, productive, and sustainable. 

While providing no-cost distribution uniformity and pump tests are core parts of the WETA program, developing training materials —especially in accessible formats like video—is valuable since it can reach a wide audience and have a lasting impact beyond the end of the WETA grant term. 

RCD MC’s initiative demonstrates how tailored, inclusive outreach can drive meaningful change on the ground. By speaking directly to the needs of Spanish-speaking farmers, they’re not just improving irrigation systems—they’re strengthening the future of agriculture in California. 

Investing in Impact: How the OARS Team Helps Deliver Climate Solutions on California Dairy and Livestock Farms 

Posted in InformationalLeave a comment

The CDFA Office of Agricultural Resilience and Sustainability (OARS) is dedicated to supporting California’s dairy and livestock farmers in their efforts to reduce greenhouse gas (GHG) emissions. As proof of that, the CDFA’s Alternative Manure Management Program (AMMP) and Dairy Digester Research and Development Program (DDRDP) awarded nearly $25 million in April 2025 to support the implementation of manure management projects on farms across the state. But these awards represent more than funding—they reflect months of technical work, partnership, and a shared commitment to climate-smart agriculture.  

Behind each award is a rigorous, multi-layered review process led by the dedicated OARS staff and program partners. This process is designed to be fair, transparent, and results-driven, ensuring that projects selected will lead to long-term, measurable methane reductions and maximize social, economic and environmental co-benefits, like enhanced nutrient management and alternative revenue streams from waste products. 

It begins with administrative and financial reviews to verify that applications meet the department’s requirements. Then, experts from academia all over the country conduct a comprehensive technical review, evaluating proposed projects based on their potential to reduce methane emissions and achieve other benefits.  

After that, OARS invites the input of the Technical Advisory Committee (TAC), comprising state and federal agency individuals with expertise in manure management, methane reduction measures, environmental impacts, and permitting in California, playing a crucial role of making sure the CDFA is selecting the best applicants within the competitive pool of candidates. In preparing the funding recommendations, OARS considers applicants’ past performance on previous grants, including their ability to complete projects on time, on budget, and deliver results. This careful and considered approach enables the selection of the most effective and impactful projects. Once the applicants are selected, the OARS team contacts each awardee and educates them on the next steps in the grant process, which are accomplished through emails, webinars, video calls, and engagement of OARS’ free-of-charge technical assistance providers when possible. 

One important note: the ideal time for public input—especially regarding scoring criteria or program rules—is during the drafting of the Request for Grant Applications (RGA), before CDFA accepts applications. Once rules are finalized and the application period begins, CDFA is unable to change them. That’s why early engagement from the public, including producers, stakeholders, and advocacy groups, is crucial to shaping a program that serves all Californians.   

By supporting manure management practices that reduce methane emissions, CDFA OARS is driving meaningful change on California’s dairy and livestock farms and supporting the state’s climate and environmental goals. These efforts are making California a better place to live and grow food, with cleaner air and water, and a more resilient agricultural industry. The state investments in climate-smart agriculture are paying dividends, and the benefits will be felt for generations to come. As the state continues to lead the way on climate action, the CDFA OARS remains committed to supporting innovative solutions that benefit the environment, the economy, and the people of California.

CDFA Looks to Get Ahead of Invasive Agricultural Pests

Posted in InformationalTagged 2 Comments

California leads the nation in specialty crop production, growing more than 400 different crops across its diverse agricultural landscape. With such variety comes a complex web of pest management challenges that demand innovative, research-driven solutions. The OARS Office of Pesticide Consultation and Analysis is continuously working to support pest management that meets agricultural needs and state policy goals. One way we do that is through our Adaptive Integrated Pest Management (IPM) for Invasive Agricultural Pests grant program, which is currently accepting applications.  
 
The program’s goal is to develop IPM program(s) or components that can be rapidly implemented when new invasive agricultural pests arrive and become established in California or when recently arrived invasive pests resurge or expand their range or host species. The program also supports research to refine and optimize existing IPM strategies to improve their effectiveness or exploring additional control measures against established invasive agricultural pests that drive extensive pesticide use but remain uncontrolled due to developed pesticide resistance. If you are researching innovative ways to control invasive pests, check out the Request for Proposals.  

One previously funded project that recently completed is ‘A proactive approach to prepare for the invasion of Tuta absoluta into California’ lead by Dr. Ian Grettenberger. This project addressed the South American tomato leafminer, Tuta absoluta, a devastating pest of tomatoes of high concern to California. If T. absoluta invades California, there will be an immediate need for management information to address its spread and to protect tomato production. Because T. absoluta has been spreading through other parts of the world, there is the opportunity to adapt existing knowledge to California’s needs.  

Management tactics tested include chemical management, biological control via indigenous and introduced natural enemies, and cultural management through variety resistance and plant breeding. Information on these methods will help growers and officials in the short-term and will help provide long-term solutions for T. absoluta in California.

Supporting Biodiversity in Olives: A Regenerative Approach to Habitat Integration

Posted in InformationalLeave a comment

At the International Olive Sustainability Conference, the Center for Regenerative Agriculture researchers demonstrate on-farm biodiversity through an interactive tour of a hedgerow funded by the CDFA Pollinator Habitat Program 

Dr. Boyd highlights a leaf serving as habitat for natural enemies to global industry professionals

In September 2024, the UC Davis Olive Center hosted the International Olive Sustainability Conference (IOSC), gathering global experts in sustainable olive production. As part of the post-conference tours, participants visited California Olive Ranch (COR), one of the partnered growers under the American Olive Oil Producers Association (AOOPA). AOOPA received funding through the CDFA’s Pollinator Habitat Program to support pollinator habitat implementation across California olive farms. The tour featured a native hedgerow planted in April 2024 to enhance biodiversity and support beneficial insect communities. 

Dr. Elizabeth Boyd, entomologist and professor, and Gerardo Tapia, graduate researcher pursuing a Master of Science in Regenerative Agriculture and supported by the Center for Regenerative Agriculture and Resilient Systems (CRARS) at California State University, Chico, led an interactive tour of the hedgerow. Using sweep nets and vials, they highlighted the presence of native pollinators and natural enemies, including parasitic wasps and predatory lacewings. Attendees had the opportunity to observe lacewing eggs within both the hedgerow and the adjacent olive grove. Additional beneficial insects observed included syrphid flies, Western European honeybees, and assassin bugs. A plant species list was distributed while participants engaged in discussion about the hedgerow’s influence on olive grove ecology, pollinator diversity, and regenerative management practices.

Hover fly (Syphridae) on the surface of a leaf of Sambucus nigra ‘elderberry’.

Although olive trees are self-pollinating and do not depend heavily on insect pollinators, the hedgerow provides critical habitat for pollinators, beneficial insects, and wildlife. COR’s implementation of this hedgerow through the Pollinator Habitat Program reflects growing interest in ecological solutions that offer multiple on- farm benefits, including erosion control, soil health, and biodiversity.

In addition, Gerardo Tapia is conducting research for his master’s thesis to evaluate how hedgerows influence the functional composition of beneficial insect communities in olive groves. The study compares field margins with and without hedgerows using non-lethal, catch-and-release methods. Functional groups studied include pollinators, predatory insects, and parasitoid wasps. 

These efforts highlight the value of habitat enhancement, even in low-pollinator-dependent systems. They also highlight the importance of collaborative approaches between producers, researchers, and agencies like CDFA in supporting a more resilient agricultural landscape!

Technical Assistance Program Builds Statewide Partnerships in Climate Smart and Conservation Agriculture 

Posted in InformationalLeave a comment

The OARS Technical Assistance (TA) Program is critical to realizing the OARS mission: “to use the best available science and knowledge from the agricultural community to design and implement practical solutions to California’s natural resource challenges that improve the environmental and economic sustainability of producing nutritious food, fiber, and energy.”   
 
The CSA TA Grant Program plays a key role in reducing the barriers farmers and ranchers face in accessing OARS incentive programs—especially for small-scale producers and socially disadvantaged farmers and ranchers. By funding a statewide network of trusted organizations, OARS ensures that producers have access to direct, hands-on support that helps them build resilience and long-term sustainability in their operations. 

What Does Technical Assistance Include? 

Technical Assistance Providers (TAPs) are embedded within OARS’ Alternative Manure Management Program (AMMP), State Water Efficiency and Enhancement Program (SWEEP) and Healthy Soils Program (HSP) to guide producers through every step of their participation. TAPs support farmers and ranchers as they: 

  • Learn about available funding 
  • Plan and design conservation or sustainability projects on their farms 
  • Navigate and apply for OARS funding 
  • Manage their grant awards 
  • Implement and complete projects on the ground, fine-tuning to optimize benefits 

In addition to one-on-one support, TAPs also conduct outreach and education in their regions, sharing success stories that highlight the real-world benefits of OARS-funded projects, and participating in the annual CDFA OARS Technical Assistance Conference.  

While the program is designed to be robust, the amount of technical assistance a producer receives can vary depending on several factors, including program complexity, location, and the capacity of the TA provider. It’s also important to note that producers need to be proactive in communicating with their TA providers to get the most from the services available. Ideally, assistance is available for every stage shown in the OARS technical assistance framework (see figure). 

Some programs, like those focused on methane reduction, may have less technical assistance built in—mainly because these projects are often engineering-heavy and the companies doing the installations typically handle most of the planning and implementation. However, producers involved in methane-related projects can still receive technical assistance for grant management and reporting through OARS-supported providers. 

OARS represents a uniquely Californian approach to sustainable agriculture and environmental stewardship. By investing in on-the-ground support and tailoring it to meet the diverse needs of California’s agricultural producers, OARS is helping lead the nation in equitable and practical climate-smart farming solutions.
