more on food sheds. Long ago (1983) I did a food self suffiency study for
the state of Minnesota as part of a larger plan for each state in the
country. This massive study was sponsored by Rodale Research Inst. in
Emmaus, PA. I don't know if they were all finished. I do know that the PA
study was very complete (as was Minnesota's, I believe!). Rodale was
concerned with regional food self suffiency at that time and was encouraging
states to become more self suffient in their food needs via these studies. I
did a lot of number crunching and data collecting; they had some conversion
figures and a general guide on how they wanted it to be done. I would call
Rodale and ask about their studies if you are interested. Good luck!
