Where does it come from? The study does not address. It also does not say why we were not affected a thousand years ago. We have been digging ponds for a very long time in this region.
I don't buy this study. We are a monsoon country with average rainfall of about 100 inches a year. Having man-made lakes is our first line of defense against India's water manipulation hegemony. No amount of upstream dams can stop us from harvesting our own rain water. This study indirectly discourages us from storing water.
I have issues with these findings.

I was also initially skeptical of this study... but a cursory reading of the original research paper convinced me this theory should be taken seriously.
Here is a link to the paper...
