Some food for thought: Not long ago I read an article about some testing done to determine how much area it took to feed one person for one year, the results was that it took 4,000 square feet to provide food for one person. This was an all vegetarian diet, with grains grown for bread, etc. I have not verified this myself, but this number seems to come up when I research that subject.

I wonder if the two systems would be compatible, I would think they would be.
I am not certain, but I recall that you can graze sheep 4 to the acre?
