Water and Human Conflict around the World Radar and satellite images have revealed an aquifer the size of Lake Erie beneath the blazing desert of Darfur in western Sudan. Is it still full of water, or did it dry up 5000 years ago? Hundreds of wells will be drilled to help scientists answer that question. If there is water under Sudan's Western province of Darfur, could it end the bloody violence between black Africans and Arab nomads that has left 200,000 dead and two million as refugees? With water in short supply from the Middle East to California, is water more important than oil as a source of human conflict?

Is it a strength — or a weakness — for the United States when the world of power politics never knows what to expect?
