Subsides for more important crops could probably work. However from what I understand, much of the popularity of almonds has to do with them being a reliable crop that are fairly easy to count on. You don't need to replant them every year, so they are less risky than other crops.

Subsidies for more important crops would probably have to match the profitability of almonds and offset the additional risk. Still, it should be possible.

I wasn't suggesting subsidies; I was suggesting doing nothing, letting farmers absorb the risk, and presumably pass it on to consumers in the form of higher prices.
