Many of the current conflicts going on in the world already are water wars in disguise, or are about dealing with degrading environments, like in the Sahel zone. Also large-scale refugee movements are about people trying to escape from places where supply for land suitable for agriculture is not increasing. This is on top of ecosystems actively degrading because of multiple other reasons as well. There are always going to be populations somewhere that manage to insulate themselves from these problems, but things will become rougher for many of us.
