It’s the ancient system of water rights and the current morass of water legislation that’s to blame for the problems caused by the drought.
Instead of asking eaters to wade through this complexity every time they pick up a fork, we need policies that make water expensive for farmers in places where it’s scarce. A market price for water would simply eliminate inefficient crops.
And, in fact, California already has a functioning water market … with one massive market failure: It’s still legal for landowners to pump as much water out of their ground as they can in many places. And it’s that market failure that is causing the true shortages in poor farming towns.
