Rapid filling of a giant dam at the headwaters of the Nile River – the world’s biggest waterway that supports millions of people – could reduce water supplies to downstream Egypt by more than one-third, new USC research shows.
A water deficit of that magnitude, if unmitigated, could potentially destabilize a politically volatile part of the world by reducing arable land in Egypt by up to 72%. The study projects that economic losses to agriculture would reach $51 billion. The gross domestic product loss would push unemployment to 24%, displacing lots of people and disrupting economies.
“Our study forecasts dire water supply impacts downstream, causing what would be the largest water stress dispute in modern human history,” said Essam Heggy, a research scientist at the USC Viterbi School of Engineering and lead author of the study.

- 41A new study shows that several disagreements between Ethiopia, Sudan and Egypt around Africa's largest hydropower plant, the new Grand Ethiopian Renaissance Dam (GERD), could be alleviated by massively expanding solar and wind power across the region. Adapting GERD operation to support grid integration of solar and wind power would…
