I hope that this is the right place to post this, but I came upon an interesting project named the urban homestead:
Surrounded by urban sprawl and just a short distance from a freeway, the Urban Homestead project is a family operated and highly productive city farm. It is also a successful, real-life working model for sustainable agriculture and eco living in urban areas and has been featured in multiple news medias both nationally and internationally.
Its a great website. The information on closed loop backyard tilapia farming is particularly useful.
PFAF.org might be useful in helping people to tailor the concept to their region.
I found Apios Americana growing wild in the forest behind our neighborhood.
" Tuber - raw or cooked[1, 2, 27, 55, 62, 63]. A delicious flavour somewhat like roasted sweet potatoes, it always receives very high marks in taste trials with us[K]. The tuber can also be dried and ground into a powder then used as a thickening in soups etc or can be added to cereal flours when making bread[132, 257]. Tubers contain 17% crude protein, this is more than 3 times that found in potatoes. The tubers can be harvested in their first year but they take 2 - 3 years to become a sizeable crop. They can be harvested at any time of the year but are at their best in the autumn. The tubers can also be harvested in the autumn and will store until at least the spring[K]. Yields of 2.3 kilos of tubers per plant have been achieved. Seed - cooked. Rather small and not produced very freely[K], they are used like peas and beans[183, 213]. A good source of protein, they can be ground into a powder and added to cereals when making bread etc. Young seedpods[55, 62, 95, 177].
