Yes, it does. But the issue is also related to changes in what people eat. My understanding is that the increased demand for almonds has been particularly problematic for the region due to how water intensive it is, for example.

What’s not clear to me is whether or not we have to grow our fruits and vegetables in California. Certainly one of the issues is that for huge swaths of our farmland elsewhere we tend to grow mono crops which are often inedible to humans (such as most of our corn). Perhaps we could grow more fruit and edible vegetables there?
