Africa’s ‘Great Green Wall’ Shifts Focus to Hold Off Desert

The project called the Great Green Wall began in 2007 with a vision for the trees to extend like a belt across the vast Sahel region, from Senegal in the west to Djibouti in the east, by 2030. But as temperatures rose and rainfall diminished, millions of the planted trees died.

Only 4% of the Great Green Wall's original goal has been met, and an estimated $43 billion would be needed to achieve the rest. With prospects for completing the barrier on time dim, organizers have shifted their focus from planting a wall of trees to trying a mosaic of smaller, more durable projects to stop desertification, including community-based efforts designed to improve lives and help the most vulnerable agriculture.

“The project that doesn’t involve the community is doomed to failure,” says Diegane Ndiaye, who is part of a group known as SOS Sahel, which has helped with planting programs in Senegal and other countries across the Sahel, a broad geographic zone between the Sahara in the north and the more temperate African savanna to the south.

African Development Bank President Akinwumi A. Adesina spoke about the importance of stopping desertification in the Sahel during the United Nations' COP26 global climate conference. He announced a commitment from the bank to mobilize $6.5 billion toward the Great Green Wall by 2025.
