After decades of drought, water is rising in the African Sahel

From the article:

Near-extinct oryx are returning. Farms are prospering as irrigation water reaches fields for the first time in decades. Farmers are even nurturing new trees on their land. Once a byword for drought and famine, the African Sahel region on the southern flank of the Sahara Desert now has more water than it has for decades. Wells are filling as water tables have risen by 13 feet or more in places. Lake Chad, which was one of Africa’s largest expanses of water before shriveling during the droughts, is recovering.

Over years of drought in the late 20th century, the sun hard baked the soils of the Sahel. Now, erratic but extreme rains are returning to this semi-arid region, causing lethal floods but also replenishing rivers, filling desert depressions, restoring water to dried riverbeds known as wadis, and sluicing rainwater off impermeable soils directly into aquifers. The process began in the 1990s but has accelerated in the past five years.

“Across the Sahel, from Ethiopia to Senegal, we have evidence of increased terrestrial water storage,” says Richard Taylor, a hydrogeologist at University College London who has led ground teams investigating the relationships between climate, land use, and groundwater recharge in the region.

Needed some good news, and this counts with qualifications. Climate changes are bringing back the weather regime which made much of the African continent the cradle of humanity. Humans are resilient, and ingenious ancestral techniques are helping to restore the groundwater tables in the Sahel now that the rainfall permits.
