The Tucson, Arizona, food bank isn’t just giving away packaged foods. This isn’t just urban permaculture—it’s a food bank. Food banks, including this one, the Community Food Bank of Southern Arizona, have been starting gardens and farms where they teach people to grow their own food. One is the scale of need—the millions of pounds of “emergency” food that a food bank has to provide. “They’re building skills—basic capacities for people to feed themselves.”There are other ways to measure a food bank’s successes than the quantity of food it gives out.
