...which like our own Sierra's and Rocky Mtns, is a valuable fresh water resource from melt-off. BTW, I never said I knew what single source of water they would fight over, just that they have burgeoning populations that their current supply won't satisfy.
I won't try to be the earth science expert on this. That is who strategy and policy experts rely upon to distill the science into trends. They then look at what the impact of those trends could be. Its only prediction, but its what we all do to avoid being caught off gaurd in a crisis.
These fresh water availability analysis and trends are publicly available, and much of the analysis on the political, economic, and military implications of the trends in water usage vs availability are also in open literature.
I'll simply report again that among many, many other things, military and political strategists are concerned about a crisis in the 10-25 years out period over fresh water shortages in Asia.
