More Frequent Drought Likely in Eastern Africa

ScienceDaily (Jan. 28, 2011)

The increased frequency of drought observed in eastern Africa over the last 20 years is likely to continue as long as global temperatures continue to rise, according to new research published in Climate Dynamics. This poses increased risk to the estimated 17.5 million people in the Greater Horn of Africa who currently face potential food shortages.

Scientists from the U.S. Geological Survey and the University of California, Santa Barbara, determined that warming of the Indian Ocean, which causes decreased rainfall in eastern Africa, is linked to global warming. These new projections of continued drought contradict previous scenarios by the Intergovernmental Panel on Climate Change predicting increased rainfall in eastern Africa.

This new research supports efforts by the USGS and the U.S. Agency for International Development to identify areas of potential drought and famine in order to target food aid and help inform agricultural development, environmental conservation, and water resources planning.
