How does the great green wall work?

The Great Green Wall is an ambitious initiative aimed at combating desertification and promoting sustainable land use across the Sahel region of Africa. It involves planting a mosaic of trees, vegetation, and sustainable agriculture practices to create a barrier against the advancing Sahara Desert. This effort not only enhances biodiversity and improves soil quality but also helps to sequester carbon, support local livelihoods, and mitigate climate change impacts. By fostering resilience in communities, the Great Green Wall aims to restore ecosystems and improve food security in the region.
