For your morning inspiration, I point you to this story about the town of Todmorden, West Yorkshire, that is striving to become self-sufficient in food by the year 2018. They already have loads of vegetable and fruit plots around town, and residents are free to be a part of the give-and-take.
I absolutely love this idea, and I'm interested to see what comes of it. I've been on my friendhbors (you know, friends who happen to be neighbors) to start something like this small-scale. Just imagine a whole town working to grow their own food! What a great example of food sovereignty.
