The first progress report on the impact of the Great Green Wall (GGW) initiative in the Sahel (September 2021) highlighted the urgency of coordinated actions involving all stakeholders if the ambitions announced in 2007 were to be achieved. Today, these actions have fallen short. To support the Pan Africa Agency of the Great Green Wall, the GGW Accelerator was created in 20211 to ensure more coordinated support to the member states, organisations and institutions of the GGW through a multi-player, structured, five-pillar approach2.
This article highlights the importance of co-constructing more accurate knowledge and developing processes to further GGW projects, in the light of these aims. It provides various examples of projects demonstrating the role of scientific research in implementing and achieving the goals of the GGW.
