Marginal lands where drought is common like Sub-Saharan Africa or the Great Plains.

It is a provocative look at how hunger, political instability, armed conflict, and patterns of humanitarian aid are all directly related to water. It underscores the real importance of climate to all of us. This issue is not just about the esoteric mechanics of atmospheric chemistry.
