Eleven sub-Saharan countries in Africa are working together to create a "Great Green Wall" (La Grande Muraille Verte) of vegetation to halt the growing of the Sahara Desert. This will be a 15 km wide strip of various types of vegetation running the continent from Dakar, Senegal to Djibouti. Local and international organizations are working together to design the route and choose the most effective and useful species of vegetation. The wall's designers hope to help farmers and stem the exodus of environmental refugees.
