OSLO (Reuters) - The world needs to find the equivalent of the flow of 20 Nile rivers by 2025 to grow enough food to feed a rising population and help avoid conflicts over water scarcity, a group of former leaders said on Monday.
Factors such as climate change would strain freshwater supplies and nations including China and India were likely to face shortages within two decades, they said, calling on the U.N. Security Council to get more involved.
