University of California Cooperative Extension

Offers information about current research in the fields of agriculture, food and nutrition, and youth development to the public.


Cooperative Extension is the nonformal county-based education and research branch of the University of California whose mission is to transfer research-based knowledge and information to local communities and residents to improve the quality of life and help solve community problems. Locally, programs are offered in gardening nutrition education for limited income youth and families, environmental education at Elkus Ranch and 4-H Youth Development. Master Gardeners are trained through UC Cooperative Extension and volunteer to extend horticulture infomation across the counties. The 4-H Youth Development Program offers youth, ages 5-19, opportunities to explore projects, develop life, leadership, and citizenship skills. 4-H clubs are community-based, cross-cultural groups guided by a diverse group of volunteers. Projects include animal science, plant science, health and leisure activities, crafts, leadership, foods and nutrition, and camping. Projects offered vary by community and are supported by research-based curriculum. Nutrition education programs target limited-income families and youth through schools, agencies and community-based organizations. Food safety and preservation information is also provided to individuals upon public service request and through publications. Elkus Ranch provides hands-on environmental educational experiences for youth and has a conference center available as a retreat or day-conference site. Group education programs serve grades K-12 as well as special needs youth. Service learning opportunities are available for all ages. Summer and holiday day camps are offered as well. UC-County based academic advisors extend information to professionals in public, private, and nonprofit sectors, working collaboratively among growers, university researchers, regulatory and local government agencies and conservation agencies to conduct practical problem-solving research to address current and emerging issues. Free and low-cost publications in agriculture, home gardening and pest management, nutrition, youth development are available through the Web site:
