Cooling is sort of a thing, but AC is pretty good now, and construction / compliance / land costs in other places vastly outweigh the (cheap, in AZ) energy needed.
Arizona is dropping the hammer on a bunch of alfalfa farms here. Interesting side note is that most of them were run and owned by Saudi companies or company. There are markedly less cotton farms than when I was a kid. The farms that I have direct knowledge of are very progressive and not afraid of innovation/change which is very encouraging.
Also of note is what Arizona does with it's share of the Colorado river. My city chose to recharge the ground water and I believe the results have been acceptable.
So it's not water usage that evaporates and can cause droughts, it can be heavily recycled back into the system.
