Great Green Wall

The Great Green Wall is an anti-desertification initiative underway in Africa’s Sahel region, on the southern edge of the Sahara Desert. It intends to restore 250 million acres (100 million hectares) of degraded land by 2030 by planting a 5,000-mile (8,000-kilometer) tree line. These Overviews show a section of the wall on the border of Mauritania and Senegal developing between 2018 and 2019. If effective, the Great Green Wall will stop the advancement of the desert, absorb 250 million tons of CO2 from the atmosphere, and create 350,000 rural jobs.
