From http://www.ers.usda.gov/statefacts/US.HTM

Total US cropland 406,424,909 acres in 2007
Total US pasture 408,832,116 acres

Assuming we should count all the pasture, and since it's land that is being ruined by agriculture, I think so, that's 815 million acres of land for food production, or 
330 million hectares. One per US person. The Egyptians did much better.

Thanks for the exercise, Dieter.
