Recent disputes over rights to transboundary water resources, such as those between India and Pakistan or Egypt and Ethiopia, have prompted predictions that increasing water scarcity as a result of climate change could lead to armed conflict.

But the historical record shows that “water wars” have been rare, and that transboundary bodies of water have occasioned cooperation as well as conflict among states.
Jeremy Allouche (Thu,) studied this question.
