Well, AbsoLoot, I'm with the urban users in SoCal, not the farmers. Why? Because the urban users pay far more for the water, per acre-foot, than the agribusiness interests. Once SoCal folks learn this, it may split the camp of "grab more water" into the "why can't we have it at the farmer's price" and "we still want subsidized water" groups.
There's clearly lots of demand, backed by sufficient money, to keep urban water flowing to SoCal. But agribusiness? Maybe not so much--remember, much of the irrigated land is naturally desert. Perhaps it will be cheaper for SoCal just to buy the agricultural land and retire it--ahem--excuse me--"return it to its natural state."
In the end, it's hard (politically, socially, etc.) not to provide water for people. But do we really want to continue to spend money and environmental resources to grow a monsoon crop (rice) in a desert?
