I can find things about the increased land-per-person needed for meat-eaters and industrialized society, but no basic estimates of how much land is needed to feed a person, or how many people x amount of land can feed. I realize this would vary according to crop, climate zone, etc. I must be framing my searches incorrectly because Wikipedia, Google, and the UN Food and Agriculture Org. site yield nothing, which is too bizarre to be believed. With all the (largely internet-based) discussion of ecological footprints, I thought this info would be everywhere.
