[Feature] Power play on the Nile

ScienceNOW - Fetched: February 25th, 2016, 9:00pm UTC

Planned in secrecy, the Grand Ethiopian Renaissance Dam will have the largest generating capacity of any in Africa. When completed next year, it will regulate the flow of 60% of Nile water that originates in the Blue Nile's highland watersheds.

An immediate concern is that Egypt could face a water shortfall if the reservoir is filled during years of low rainfall. Supporters say the dam will be a boon for Ethiopia, one of the least developed countries in the world.
