With water increasingly scarce in the West, a new program is allowing some farmers to sell their allotment of it for whatever price they can find, but it comes with a hitch... They can continue to farm all their land, or they can stop farming some of it and earn more than $500 an acre — more than the market value of a crop like alfalfa in a given year — simply by not using the water required to nourish those crops. Water saved is sent on to thirsty cities and suburbs to the west: San Diego, Los Angeles and Palm Springs.
