Great Green Wall: Africa's Ambitious Project Falls Short

Launched in 2007 by the African Union, the Great Green Wall aimed to plant a 4,350-mile wall of trees across Africa to combat desertification in the Sahel. The ambitious multi-billion dollar project envisioned re-greening 250 million acres, sequestering carbon, and creating millions of jobs.

Eighteen years later, the project has fallen significantly short of its goals. Many tree-planting efforts failed due to unsuitable species, lack of water, and insufficient local community incentives. Projects like Abdi Guelleh's farm in Djibouti, initially a success with irrigation, later reverted to desert when the water supply dwindled and equipment broke.

Studies in Senegal indicate minimal ecological benefits from reforestation plots, with social impacts being periodic and short-lived. Despite billions in international funding pledged and disbursed, tracking the money and its impact has been challenging due to coordination issues and opaque financing structures.

While some localized successes exist, such as dune stabilization in Chad supported by SOS Sahel, the overall Great Green Wall remains largely unrealized. Challenges include funding shortfalls, political instability in some participating countries, and a lack of systematic involvement from national agencies in project implementation.
