What Is Regenerative Agriculture?

Regenerative Agriculture is both a tool and a vision.

It’s a tool for reversing the flow of greenhouse gas emissions, for example, and creating an enormous repository of carbon in the soil. It’s a vision for a future agriculture that combines indigenous knowledge with western science and technology, a future that re-establishes relationships between humans, crops, animals, soil, and ecosystems.

Our planet can provide safe, nutritious food and fiber. We can listen to the wisdom of indigenous cultures who have studied the complex relationships between humans, animals, crops, and ecosystems. We have access to the enormous agricultural research capabilities of federal agencies, land grant universities, the private sector, and thousands of farmers learning more each year. We have the ability to create a food and agricultural system that reduces racial inequities and other injustices.

Despite this abundance, global food and ecological systems are facing continuous crises, including depleted soils, contaminated water, accelerated greenhouse gas emissions, viral outbreaks, farm bankruptcies, enormous wealth disparities, and increasing hunger.

Regenerative Agriculture is any practice, process or management approach that enhances the functioning of the systems on which it relies. This includes core ecosystem cycles such as energy, water and minerals by enhancing biological function. It also includes improving economic and social systems. In other words, any practice that makes the land, community and bottom-line healthier year after year is regenerative. It is based on outcomes, distinguishing it from most sustainable/conservation agriculture efforts.

Regenerative Agriculture is:

  • Not a new idea. While the use of the term has increased dramatically, the concept goes back millenia. It’s a paradigm shift from an emphasis largely on production to recognizing multiple priorities for agriculture, and advancing those priorities by incorporating indigenous knowledge, modern research, adaptive learning, and a deep respect for farmer wisdom.
  • Difficult to define. Regenerative Agriculture is not a well-delineated set of practices, a certified type of farming, or solely based on a series of metrics such as concentrations of soil organic carbon and water quality. It is better thought of as steps toward solving multiple crises.
  • Grounded in community. Agriculture touches us in many ways besides the calories produced. Regenerative agriculture provides a framework for valuing those touchpoints.
  • A journey. It moves us toward a world of plentiful food and fiber production, restored ecosystems, well-functioning water and carbon cycles, flourishing communities, and a just, equitable and thriving food economy.

Who Are We?
The Regenerative Agriculture Foundation

RAF is an intermediary funder, launched in 2016 through the vision of Kevin Boyer and the generous support of the 11th Hour Project. Regenerative agriculture can advance multiple different goals, from climate change mitigation and ecosystem services to rural economic development to public health to racial equity.

RAF staff and partners keep up-to-date on research, policy, markets, and the activities of nonprofit organizations in order to provide funding partners with the most promising opportunities for driving impact. Continuous learning is a priority, and RAF became a founding partner of the Funders for Regenerative Agriculture (FORA) in order to create a forum for learning. RAF also collaborates with funding partners in the California Foodshed Funders and the Sustainable Agriculture and Food Systems Funders.

RAF makes grants twice a year (summer and winter) using an invitation-only process. Nonprofit organizations seeking grants should use this inquiry form for bringing a proposal idea to the attention of RAF staff.

Our Vision

We envision a world where the inherent value of people, plants, animals, community, and the planet are honored and stewarded in a way that regenerates both human and natural communities.

Our Mission

The mission of the Regenerative Agriculture Foundation is to foster the economic, policy, and knowledge conditions that support land stewardship, provide climate solutions, protect freshwater and oceans, advance racial equity and a just economy, support thriving rural communities, and sustain diverse human and ecological life.
