The Great Green Wall: An overview and lessons learnt

The Great Green Wall (GGW) is the most ambitious afforestation, reforestation and revegetation programme in sub-Saharan Africa. As such it represents an example of recent attempts to initiate “green mega-projects” that cut across large geographical regions and involve multiple actors. More specifically, it can be seen as an attempt to apply Nature-based Solutions (NbS) at a grand scale. Based on a literature review, this Working Paper seeks to provide a general overview of the evolution of the GGW and examines how scholars and experts assess the GGW and its progress at the current stage.
