CE

As a land-grant institution, the University of California Cooperative Extension (CE) specialists are dedicated to the welfare, development and protection of California agriculture and are the outreach arm the University of California’s Agricultural and Natural Resources program. CE specialists are headquartered at UC Riverside, UC Davis and UC Berkeley and provide statewide leadership to farm advisors and faculty, and carry out outreach programs at the state and local level. CE specialists perform both basic and applied research and thereby are a critical link in the research continuum that addresses problems that are encountered in California agriculture. On May 2014, CE will celebrate 100 years of service to California and a brief history can be found at http://cesonoma.ucanr.edu/100_Year_Anniversary/History/. Useful links are also provided below.

The UC Riverside CE specialists provide a wide range of expertise focusing on over 100 crops and issues in conservation biology, the environment, organic agriculture, postharvest physiology, and agricultural biotechnology. Our CE faculty and areas of expertise and useful links are provided below.
