Can Ethiopia and Egypt reach a deal that will provide 160 million people living along the Nile with sufficient water?
Egypt and Ethiopia are looking to put past disputes over the use of the water from the River Nile behind them.

But with upstream countries in desperate need of energy, we ask: How long can these new deals last? And who is set to benefit the most?
