In the 21st century American farm exports "will be beyond anythingwe even contemplate today," according to former U.S. Secretary of Agriculture Clayton Yeutter. He will present his predictions about U.S. agriculture and the economy as one of three nationally known speakers to discuss "The Shape of Agriculture in the 21st Century" at a UC symposium, open to the public, Thursday, June 22, in Sacramento. Yeutter expects dramatic changes in future ag policy. "Within a few years after the turn of the century, American agricultural economists will have almost forgotten the traditional farm policies of the 1930s and after. Those policies will seem like historical aberrations." Robert Fri, president of the nonprofit Washington, D.C., research organization Resources for the Future, will give an environmental perspective, and George Breuning, a UC Davis professor and director of the Center for Engineering Plants for Resistance Against Pathogens, will cover the impacts of science on agriculture. A panel of ag experts will respond to the speakers. The free symposium will be 1-5 p.m. at the Radisson Hotel.
