Because of climate change and just climate variation there are areas where water was in abundance, and is now scarce. Rainfall patterns changed, glaciers are melting faster than can be saved for later use, but mostly I think the problem is that people are so far removed from reality that they believe they can put millions and millions of people in the desert and expect enough water to come their way as if by magic. This is why it's a desert......
All the talk about turning out economy towards sustainability keeps getting bogged down in a slough of soggy thinking.
