I think this is a great idea if you are looking to start a CSA, but can’t purchase land. Another idea I see that could stem from this is sharing your yard with apartment dwellers. A lot of homeowners have yards and want organic, local produce, but do not have the desire or the time to work in a garden. I am sure a number of these homeowners know someone who has the desire to grow their own food, but does not have the space. The homeowners could allow their friends to farm their land and use their water in exchange for some fresh produce. Both parties get something they want out of the deal and it is better for the environment.
