Study Finds Pattern of Severe Droughts in Africa


For at least 3,000 years, a drumbeat of potent droughts, far longer and more severe than any experienced recently, have seared a belt of sub-Saharan Africa that is now home to tens of millions of the world’s poorest people, climate researchers report in a new study.

“Many of the 390 million people in Africa living on less than $1.25 a day are smallholder farmers that depend on two things: rain and land,” he said. “Even small climate blips such as a delay in rains, a modest shortening of the drought cycle, can have catastrophic effects.”

Given the sub-Saharan region’s persistent vulnerability, Mr. Watkins added, the new findings and the prospect of further global warming could be “early warning signs for an unprecedented and catastrophic reversal in human development.”
