No, because the price would go up and some of the crop would get grown in other states. Hard to say what the exact percentage would stabilize at, though, and it certainly takes a long time to plant orchards, etc.

But what is the percentage of income taken by produce? Not very high, I'd guess. Probably affect the poor the most.

Some crops would take years to rebound, like nuts, which are both water intensive and take years to mature.

The US is a net food exporter by a large margin.
