Most cash crops are already genetically modified to make them more drought resistant. The problem is that no one can make crops drought proof. And drought restitant crops still do not produce as much as they would with rain.
the above is correct. Hybrids are available that only need a small amount of moisture, but they were developed for arid land such as in africa. the yield is much lower so no one would plant them in the USA. Even with the drought USA plantings are so dense we will net far more corn than planting a drought resistant variety. In addition the drought corn is not a total loss, even the worst can be ground into livestock feed. One of the subsidies paid to farmers is the rental by the government of buffer strips, basically the edge of the field or places that are at higher erosion risk. For a few dollars investment the topsoil is retained and while it might be currently dry the land is in no danger of returning to the dustbowls of the past. In the old days the farmers were desperate and lost alot of topsoil in bad practices. the government now controls almost all farming practices and the land is in excellent health. It costs a few dollars but when you consider that food stamps make up 80 percent of the Dept of Agriculture's budget, farm supports return more value than most anything else the government sticks its hand in.
Of course if you all don't mind lead in your milk, clenbuterol in your meat and food prices much lower than much of the world than feel free to bash the farm industry.
