It just occured to me that Civ needs something in it to reflect the advances in farming techniques through the ages. In Civ 2 there was refrigeration, which let you build supermarkets, which made each irrigated square produce one more food. I think it was really the tractor and other types of machinery that vastly increased farm production, so maybe when you get motorized transportation or mass production, or even a new technology, there should be something that increases crop yields. Farmers today feed many more people on much less land, but in civ farms produce the same in 4000 B.C. as in 2000 A.D.
