A. competition among countries for scarce water sources

Explanation:

It was estimated in 1998 that by the year 2025, 25 African countries will be actively suffering from water scarcity. Currently, this is the reality of many in Africa as over 320 million people are believed to have no access to clean water.

Competition for the scarce water resources that the continent runs on has led many to believe that in future, Water wars will be fought in Africa. This belief has grown due to recent events which have seen Egypt and Ethiopia, both of which share the Nile, in increasing hostility with each other over the other's rights to the Nile.
