The Great Green Wall initiative aims to stop the spread of the Sahara Desert by restoring 100 million hectares of land across 11 countries in North Africa.
The Sahel region, a semi-arid belt that acts as a buffer zone just south of the desert, is most affected. Water, already scarce, is becoming scarcer. Soil quality is deteriorating, and a lack of vegetation is leading to food insecurity. The UN estimates roughly 135 million people who depend on these degraded lands are at risk.More Related News
