+1 I agree. I would extend this to all farming and meat production, even in non-arid areas.

I read Peter Zeihan's pretty good book "THE END OF THE WORLD IS JUST THE BEGINNING, Mapping the Collapse of Globalization" and he offers lots of good advice for sustaining the human population: optimize on foods like wheat that provide protein and carbs, using fewer resources like water. Peter has lots of equivalent YouTube content if you don't want to buy the book.
