The Nile River, the world's longest river, travels more than 6,700 km from its farthest source at the headwaters of the Kagera Basin in Rwanda and Burundi to its delta in Egypt on the Mediterranean Sea. Today the Basin is home to an estimated 160 million people, and more than 300 million people live in the ten countries that share and depend on Nile waters. Because of its complex history, there is only limited cooperation in the development and management of the Nile, with unilateral action causing dispute, and even threatening regional security, according to the Ethiopian Reporter.
