"Urban agriculture" and "food forestry" may sound like a paradox considering the last century has seen urban growth paving over our prime agricultural lands, and forests around the world getting cut down for commercial crops.  However, for most of our history, human settlements were integrally connected to their local sources of food, veggies, fruit, eggs, fish, etc. and the best food systems around the world were those that worked with nature.  Even in Los Angeles County, one hundred years ago, we were one of the most agriculturally productive counties in the United States, and more than half our population were farmers and ranchers.  Demographics and development have changed dramatically in the last one hundred years, and now we find ourselves perirously vulnerable, completely dependent on a complicated, distant, and dangerously unsustainable food system.  Clearly, when considering options for a sustainable urban food system, we ultimately realize that we will need more people to take up the vocation of urban farmer to plan and develop urban food systems, from kitchen veggie/herb gardens, to aquaculture, to integrated food forests.
