Latest Sahel drought Stories
WASHINGTON, Feb. 12, 2015 /PRNewswire-USNewswire/ -- Droughts in the U.S.
In the 1980s, decades of drought in central Africa reached the worst point. This caused Lake Chad, a shallow lake used to water crops in neighboring countries, to dry out almost completely.
Cyclical changes in atmospheric pressure and sea surface temperature in the North Atlantic Ocean affect drought in the Sahel region on the southern Sahara rim.
The kinds of devastating droughts that claimed the lives of more than 100,000 people in Africaâ€™s Sahel region in the 1960â€™s and 70â€™s may represent a normal natural occurrence rather than an anomaly, according to new research.
