As one of the best entrepreneurial incubators of this century, I think small farms in urban, exurban and suburban areas are extremely useful and appropriate. In NYC, the juxtaposition of industrial or heavily urban areas next to active green space is startling to say the least. I wonder when cities will start to add edible landscaping (especially fruit trees) to their landscaping plans? I understand they won’t be putting them on the middle of busy streetscapes, but why not apple, pear, peach, cherry, citrus, avocado and such in quiet nooks and crannies of the city?
I think market communities could accelerate that by donating trees every year to their city, and even using the market community to work as volunteers to maintain them where appropriate. If every market quietly added some permanent food to their community, we might start another revolution of food returning to public spaces.
