Since there is already little water left in the Nile when it reaches the Mediterranean, if either Sudan or Ethiopia takes more water, then Egypt will get less, making it increasingly difficult to feed an additional 46 million people. Although there is an existing water rights agreement among the three countries, Ethiopia receives only a minuscule share of water. Given its aspirations for a better life — and with the Nile being one of its few natural resources — Ethiopia will undoubtedly want to take more.

In the Aral Sea basin in Central Asia, there is an uneasy arrangement among five countries over the sharing of the two rivers, the Amu Darya and the Syr Darya, which drain into the sea. The demand for water in Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan already exceeds the flow of the two rivers by 25 percent. Turkmenistan, which is upstream on the Amu Darya, is planning to develop another half-million hectares of irrigated agriculture. Racked by insurgencies, the region lacks the cooperation needed to manage its scarce water resources. Geographer Sarah O’Hara of the University of Nottingham, who studies the region’s water problems, says, “We talk about the developing world and the developed world, but this is the deteriorating world.”
