More African droughts bite hard as global temps rise

The increased frequency of drought conditions in Eastern Africa
for the last 20 years is likely to continue while global
temperatures rise, researchers say.
Frequent or prolonged drought poses increased risk to millions of
people in Kenya, Ethiopia and Somalia, who currently face
potential food shortages, researchers at the University of
California, Santa Barbara, and the U.S. Geological Survey say.
They say warming of the Indian Ocean causing decreased rainfall in
eastern Africa is linked to global warming, a UCSB release
reported Friday.
"Global temperatures are predicted to continue increasing, and we
anticipate that average precipitation totals in Kenya and Ethiopia
will continue decreasing or remain below the historical average,"
Chris Funk, a USGS scientist, says. "The decreased rainfall in
Eastern Africa is most pronounced in the March to June season,
when substantial rainfall usually occurs."
The research is part of an effort to identify areas of potential
drought and famine, to target food aid and help inform
agricultural development, environmental conservation and water
resources planning.
"Forecasting precipitation variability from year to year is
difficult, and research on the links between global change and
precipitation in specific regions is ongoing so that more accurate
projections of future precipitation can be developed," Park
Williams, a postdoctoral fellow in the UCSB Department of
Geography, says.
