We actually don't even necessarily have to shift agriculture itself. Right now, the agriculture is water-intensive: the only reason it's so water-intensive is because water in the West is cheap. We know how to grow produce using less water-intensive methods (see Eurofresh Farms in Willcox, AZ), it just isn't very economically viable, because water is not the expensive part of agriculture (for the producer).
