Summary The production and use of biofuel crops and biomass for energy will help Californians reduce their consumption of fossil carbon sources for energy and reduce the state’s contribution to global warming. A state-based crop and biomass based industry will develop successfully if crops and other biomass sources can be produced efficiently, profitably and sustainably. We believe it is vital for ANR and the University of California to be centrally involved with the rapidly developing biofuel industry in California. Through a new ANR Bioenergy Work Group (BEWG), we will link county based CE advisors, campus-based specialists, and campus-based researchers at the Davis, Berkeley and other UC campuses with farmers, developing bioenergy industries and policy makers in California. The BEWG will attempt to contribute in a significant way to the successful creation of a new bioenergy sector as part of California’s agricultural portfolio. The BEWG will assess the needs of industry groups for UC involvement and plan, carry out or otherwise help with targeted research to assist biofuel development in California. The BEWG will do outreach, create useful newsletters and publications, create in-service training opportunities and short courses for ANR personnel and others, and seek additional extramural funding to advance the work group’s objectives. By working with farmers and bioenergy industries to help create bioenergy systems through applied research, outreach and facilitation, the BEWG will insure that the University’s exceptional research and outreach capacities are used effectively to advance this important new area of public interest. Because of the urgency and speed with which state and campus-based efforts are developing, we believe it is important for ANR to quickly develop a leadership position and provide service in this important area of agriculture.
