Fleet Farming is a perfect example of a community based urban farming effort that promotes a sharing economy. They have a very organized system for making everything work including making use of fruits that would otherwise be spoiled--a gleaning operation meant to provide cheap and free food to the community. You can even pay them to set up your own food garden and harvest for yourself. If any good souls check them out, they would be the perfect rehab system for the urban poor, the rural disadvantaged and everyone else who wants to survive without being part of any rat race.
