   From what I understand, Bermuda has done a lot of work using new and old tdroaws sustainability on a limited island. You might want to look into what they do and then scratch the surface.Have you ever visited care2.com? It has a lot of info, numerous links, and then links to links. Don’t forget to consider solar-thermal energy assistance and use; you pre-heat water or other materials stragetically placed and/or plumbed to reduce the solar power load. A lot of folks currently reducing thier grid use and/or going off the grid are returning to 12 volt systems or sub-systems. (It is my understanding that back in the day, obviously before my day, that 12 volt electricty arrived at homes long before the current 110/220.) Also, have you ever been to cityfarmer.org? It is out of Vancouver, BC and its goal is to promote city farming in the Vancouver area and world wide. Certainly at one time, it had a board for the posting of urban farming research, papers, and the more. It also had a posting of a guy who did a paper (thesis/thesis related I think) about establishing farming capabilities in poor, urban areas with limited water access and use. His area was some place in Africa. Posted were some dimensions and drawings of some raised beds using found scrap materials for the growing of lettuces and I think it was tomatoes. The beds included different levels and a slucing system that were arrived at. Included in the discussion were alternative material suggestions, critical technical aspects about the bed dimentions and slucing system, yield discussion, and future and alternative design considerations one could/should make. I’m not sure if this board or posting still exist but, the administrator can probably get you information from the archives. Certainly in the past, this was a good site for connecting to others doing urban and other food production exploration under different conditions.
