In an attempt to address some of the environmental issues related to agricultural and urban sprawl, UC Davis will host a free public town hall meeting Tuesday, Aug. 17, in Exhibit Hall "D" of the Sacramento Convention Center. Focused on "Environmental Health on the Ag/Urban Frontier," the meeting will highlight issues such as air and water quality, land use and agricultural practices, and the economics of environmental management. Key speakers will include Kenneth Olden, director of the National Institute of Environmental Health Sciences; Robert Costanza, an economics professor at the University of Maryland; Richard Rominger, deputy director of the U.S. Department of Agriculture as well as a Winters farmer; and Byron Sher, state senator from California's 11th district and co-author of the recent headwaters agreement. The meeting, which will last from noon to 4:30 p.m., is sponsored by the UC Davis Center for Environmental Health Sciences and is being held in coordination with the International Congress on Ecosystem Health. It will include a moderated panel discussion from 3 p.m. to 4:30 p.m. Microphones will be provided to allow for audience participation. Although the town hall meeting is free of charge, the noon banquet will cost $10. Banquet reservations may be made by phoning (530) 752-4251.
