ETHIOPIA-NILE-DAM

A photo taken on March 31, 2015 shows the Grand Renaissance Dam under construction near the Sudanese-Ethiopia border. Ethiopia began diverting the Blue Nile in May 2013 to build the 6,000 megawatt dam, which will be Africa's largest when completed in 2017. The leaders of Egypt and Ethiopia promised on March 24 to boost cooperation on the Nile river and turn a page on a long-running row over Addis Ababa's controversial dam project. Egypt, heavily reliant for millennia on the Nile for agriculture and drinking water, feared that the Grand Renaissance Dam would decrease its water supply.
