River

Nile

The Nile is the world's longest river and its most asymmetric water dispute: the Blue Nile's Ethiopian highlands supply ~85% of the flow that Egypt, 2,500 km downstream, depends on almost entirely. Whoever holds the headwaters holds a valve on a nation of 110 million — the entire GERD standoff in one sentence.
