Ruth Meghiddo's Farm Urbana envisions bringing food production to the roofs of our cities. In a Downtown Los Angeles' project, on the rooftop of a 170-unit apartment building, she shows how the goal can be achieved through the use of the water-conserving Tower Gardens vertical system. Two professors from the University of California, Irvine, Bill Tomlinson and Don Patterson, took interest in the project for their course at the Bren School of Information and Computer Sciences. "It is not just about quality food production," said Ruth. "It is about health, wellness, community, sustainability and resilience as well."
