My takeaway was that 97% of US farmland would be unaffected by aquifer collapse. The 3% that would be affected (and that's assuming every aquifer in the country goes dry, which is not at risk of happening) those farms might become completely nonviable, or they might be able to shift to less water intensive crops and methods. In either case, aquifer collapse is not a significant threat to our food supply. Nonetheless, it is prudent to preserve those water sources. re: farms near cities, I think it varies a lot by region. Growing thirsty crops near LA is going to be a lot harder than near Houston.
