Egypt is one of the water-poorest countries in the world. One of the biggest challenges facing it now and in the coming years is securing enough water for its growing population, an enormous challenge given the double threat posed by climate change and the Grand Ethiopian Renaissance Dam (GERD).

Whatever measures Egypt takes to optimise its water use will mainly depend on the Nile.

Yet Ethiopia has failed to provide clear evidence, let alone commit itself to a legally binding agreement that guarantees GERD will not affect the amount of water coming to Egypt, despite nearly a decade of negotiations.
