Sustainable Water Management: What Are the Challenges for the Great Green Wall?

The Great Green Wall (GGW) initiative aims to create a green strip through the Sahel, some 8,000 km long and 15 km wide, to restore degraded land. Launched in 2021, the GGW Accelerator focuses on five pillars, but does not directly address water resources. This paper is based on several Agence Française de Développement (AFD) studies and a review of the literature. It examines the role of water resources in the acceleration of the GGW.
