On his blog, UOP economist Dr. Jeffrey Michael has noted that a peripheral canal or tunnel could actually increase drought risk. Here’s why:
A peripheral canal or tunnel will increase the cost of water for farmers like those on the west side. These farmers have already planted more lucrative permanent crops like almonds despite the uncertainty of water supplies. If water costs more, they will be even more likely to plant orchards to try to recover some of the costs. This will make them more vulnerable in the inevitable drought years.
