The Great Green Wall of Africa is a project aimed at restoring a strip of land stretching from Senegal to Djibouti, with the goal of strengthening food security and improving the health and standard of living of local communities. The work of the Téssékéré International Human-Environment Observatory documents the diverse range of initiatives being implemented, tailored not only to the environment but also to the local people. In Senegal, the Fulani people of the Ferlo region bear witness to this.
