About Us

We Are The Bridge Between Local Issues And The Power Of UC Research


Throughout California, the UC’s 64 Cooperative Extension offices are local problem-solving centers. We are the bridge between local issues and the power of UC research. Our county-based staff is part of the community – we live and work in the areas we serve.

More than 300 campus-based specialists and county-based advisors work to bring practical, unbiased, science-based answers to problems across California.

As part of the agricultural community, we help farmers develop more-efficient growing methods, solve pest management problems, and improve irrigation methods.

As stewards of the land and water, we help develop smart water-use strategies; develop wildfire, pollution prevention, and invasive species education; and help preserve natural areas, waterways and farmland.

As advocates for healthy communities, we promote healthy diets and exercise for better health, help Californians learn to choose the most nutritious foods and help shape the citizens of tomorrow through the 4-H Youth Development Program.

And thousands of volunteers extend the reach of our work through the Master Gardener Program and the California 4-H Youth Development Program.

We work in full partnership with federal, state, county and private resources.

We are stewards, problem-solvers, catalysts, collaborators and educators.

We are the University of California Cooperative Extension.
