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.
- ambitious = good but difficult to do
- bind = here: to make it stay in the ground and not let it escape into the atmosphere
- carbon dioxide = gas that is produced when animals breathe out or when carbon is burned in the air
- claim = to say that something is true, even if you cannot prove it
- commit = here: to say that you will do something
- desert = land where it is always dry and where there are few plants and a lot of rocks and sand
- desertification = when farmland changes into desert
- drought = long period of dry weather when there is not enough water for plants and animals to live
- FAO = Food and Agriculture Organisation = organisation in the United Nations that helps produce food and gives it to poor people around the world
- fertile = here: land that is good enough to produce food
- mainly = mostly
- move forward = to make progress; here: to continue building
- permanent = existing for a long time
- provide = give
- Sahel zone = dry area of land between the Sahara desert and tropical Africa
- shortage = not enough of something
- stretch = reach from one place to another
- structure = object that has been built
