I could go on and on about the geopolitical tensions associated with the water resource. It's certainly a factor that contributes to geopolitical tensions elsewhere in the world, particularly in the Middle East, the Nile basin and central Asia.

Even within societies, this sometimes fuels extremely serious social tensions. Take, for example, the Cauvery river basin in southern India, where there are regular riots that claim victims every summer.
