Ganas is an urban intentional community (used to be called a "hippie commune"). I'm growing veggies in a couple of back/front yards, sidewalk strip, and on some garage roofs. We compost most of our food waste (what doesn't go to the chickens, and, then, the chicken bedding goes on the compost pile too), so I have plenty of organic matter for the beds.
