Water conservation up means use up

That's the the gist of this paper ("Water conservation in irrigation can increase water use") published in the Proceedings of the National Academy of Sciences by an agricultural economist and water engineer.

I thank Johannes for bringing it to my attention in a comment on an earlier post where I was discussing the lack of economic (or human) content in some engineering models that assume high-efficiency irrigation will (1) be done without a good incentive and (2) "save" water for use elsewhere. Glad to see that facts fit the theory (that's based on facts, actually :)
