>why don't we just ban exportation of our farmed food in for example a red zone district due to water shortage, i.e. it can only feed us. I bet the water usage would drop significantly. Or instead of idiotic regulations that will be gamed and filled with loopholes, just make the farmers pay the market rate for water. That will drive up the cost of the farm output enough that it won't be competitive and farmers won't need so much water.
