It doesn’t take an agricultural expert to know that you can’t grow vegetables without water. So it wasn’t surprising that after hundreds of people marching under the banner “Occupy the Farm” took over a University of California (UC) agricultural testing station on April 22, UC officials responded by shutting off water to the site. The next day, a late-season storm brought a half-inch of rain to the San Francisco Bay Area, irrigating the thousands of vegetable starts in the ground and lifting the spirits of the urban farming activists who are determined to save the site from development. Score: Occupiers, 1 – UC administrators, 0. Social change activists in Berkeley, Calif., have always been ahead of the curve. Today, May Day, is the spring reemergence for the Occupy movement as activists around the United States engage in work stoppages, street marches, and various forms of civil disobedience to press their demands for a more equitable economy. The folks with Occupy the Farm got started early. On Earth Day, they marched from Berkeley’s Ohlone Park to a five-acre plot of land in the adjacent bedroom community of Albany. They cut the locks on the gates of the UC-Berkeley and U.S. Department of Agriculture (USDA) field trial plot, pulled up nearly an acre of thick mustard growing there, and got busy working the soil with a pair of rented rototillers. Then, scores of volunteers planted 150-foot rows of lettuce, beans, cucumbers, and leafy greens. By the end of Earth Day, the Bay Area had a new urban farm.
