“The Great Green Wall” is the project that seeks to save the African region of the Sahel (from the Arab Sahil: “Edge of the Desert”), a strip of sub-Saharan Africa located between the Sahara Desert to the north and the Sudanese savanna in the south and between the Atlantic to the west and the Red Sea to the east. This is the region most affected by global warming.

The project was an idea as early as 1952, when Richard St. Barbe Baker, an English environmental activist, proposed planting a significant number of trees in sub-Saharan Africa to stem desertification in Africa. The idea was reconsidered in 2002 at the N’Djamena summit in Chad on the occasion of the World Day against Desertification and Drought, and presented in 2005 by the Saharawi and Saharan Saharawi Leaders’ Conference in Ouagadougou, Burkina Faso and adopted.
