There was a book I came across at the library > 10 years ago published back in the late 70's/early 80's that I think was called "Edible City" based around a coalition in Eugene, OR. It looks like there is a book with that title now on Amazon regarding a
project in Toronto, so I may be off a bit on the name.
It was a very "homemade" feeling book, but it had a lot of insights in to how a city could truly be made in to a productive and healthy environment.
This site has a mention of the Edible City Resource Center, which if I recall was a sponsored site where people could come for free and learn about composting, vermiculture, growing veg/fruit/nuts and get classes in food storage, like canning.
http://www.lanefood.org/about-wffc.php I see there is a manual on Amazon, as well. This may be the actual book that I came across.
