Global heating could bring many more bouts of severe drought as well as increased flooding to Africa than previously forecast, scientists have warned.

New research says the continent will experience many extreme outbreaks of intense rainfall over the next 80 years. These could trigger devastating floods, storms and disruption of farming. In addition, these events are likely to be interspersed with more crippling droughts during the growing season and these could also damage crop and food production.

“Essentially we have found that both ends of Africa’s weather extremes will get more severe,” said Elizabeth Kendon of the Met Office’s Hadley Centre in Exeter. “The wet extreme will get worse, but also the appearance of dry spells during the growing season will also get more severe.”

In the past it was thought intense rainfalls would occur in a region every 30 years. The new study, funded by UK foreign aid, indicates this is more likely to happen every three or four years.
