Africa’s Great Green Wall

Africa’s Great Green Wall is a project to create a natural wall of trees across Africa. The wall will stretch across Africa south of the Sahara desert  from the Atlantic Ocean to the Horn of Africa. When finished the 8,000 km long and 15 km wide Great Green Wall will be the largest man-made structure  on earth.

The project started in 2007 in an attempt to fight desertification, permanent drought  and food shortages in countries of the Sahel zone, one of the poorest regions in the world.

However, the building of the wall is not moving forward fast enough. Up to now, only 15% of the trees have already been planted, mainly in Senegal.  The ambitious project will cost over $4 billion. 21 African countries, the World Bank, the FAO and the French government have committed themselves to financing the natural wall.

The Great Green Wall will run through an area, in which the dry season can last up to 10 months a year. Experts claim that by 2025 a large part of the  fertile land in the region could be lost if nothing is done to save it. In addition, the wall is expected to provide food for 20 million Africans and  also bind millions of tons of carbon dioxide.
