Sudan, Egypt and Ethiopia agreed on Sunday to hold further talks this month to resolve their long-running dispute over Addis Ababa’s huge dam on the Blue Nile, Sudan’s water ministry said. Al Jazeera reports that this week’s talks will pave the way “for the resumption of tripartite negotiations on Sunday January 10 in the hope of concluding by the end of January”. Ethiopia says the hydroelectric power produced at the dam is vital to meet the power needs of its population and insists downstream countries’ water supplies will not be affected but key questions remain about how much water Ethiopia will release downstream if a multiyear drought occurs and how the three countries will resolve any future disputes.
