> Of course farmers need to devise more efficient ways to water their crops, but I think it's strange urban dwellers don't understand the inelasticity of water for farming. At home one can cut showers from 15 mins down to 5 or two. On the farm it means not planting x acres that year. Isn't that the opposite of the truth? I've seen statistics about the water efficiency of agriculture, and it seems to be that relatively modest investments can drastically increase the efficiency. Of course, when water is cheap, there's no incentive to increase efficiency.
