The other problem is you should not be growing crops that require lots of water in the desert in the first place. If we would work with nature there will be little or no major consequences in the future.
People seem to actually care a little more today than our ancestors. It has been a while since one of our rivers caught on fire. We still ignore some of the most devastating problems. Most of our estuaries are now dead zones. The dead zone created by the Mississippi river is measured in thousands of square miles and a direct result of improper agriculture practices of 30+ states and Canada.
Just cleaning up the mess we currently are making would be a great first step. Then cleaning up the mess we have made in the past would be another great step. It is not our use of water that is the problem but how we use it. We can use the water from a river over and over again as it flows to the sea as long as we return the water to the river as clean as we took it. This also applies to our lakes.
Our desert aquafers were dropping before we started pumping the water out of them. That means they will not recover. How long they last is determined by how fast we pump them dry or unusable. Plus eventually the natural salts in ground water will render the land useless eventually as well unless their is enough rain to wash the salts back out of the soil. If we are going to farm the desert we should grow desert crops and only water them in the rare occasion of drought.
