Great green wall (Great Green Wall)

Main article: Africa

According to the plan for the end of 2019 the Great green wall in Africa should have the extent of 8,000 km and the area of 100 million hectares.

This project was officially approved in 2005 and started two years later. "The great green wall" which is sometimes in addition called "A great wall of Africa" is the initiative directed to fight against desertification of the Sahelo region (North Africa) and its effects. The project plans recultivation of 100 million hectares of the degrading earth to the south from the Sahara Desert and sequestration of 250 million tons of carbon by 2030.

In addition to the solution of environmental problems, the large-scale project of gardening of desert lands is 10 million additional jobs and expansion of economic opportunities for youth and also ensuring bigger food security for millions of people. Besides 8,000 km of the woods near the Sahara Desert are practically a nature miracle which will perhaps attract tourists.

This ecological project derives inspiration from other similar projects worldwide. Among them - the Algerian green dam, the large-scale program of reforestation for protection and development of the presahara districts, and the Green Chinese wall, a series of the wind forest bands in China constraining expansion of the Gobi Desert.

By the end of 2019 in Ethiopia, Senegal, Nigeria, Sudan, Burkina Faso, Mali, Niger and several other countries more than 20 million hectares of the earth were recovered.

Some climatologists criticize the Great Green Wall program, claiming that not to solve a desertification problem in this region with its help. According to Alessandra Giannini, the employee of the International research institute of climate and societies (USA), the Sahara Desert it was formed as a result of the geographical location and droughty climate, and the quantity of vegetation will not change an amount of precipitation.

But even critics recognize that disembarkation of forest belts will help to reduce negative effects of climate change in this region as a result of which rainfall became less frequent, but more intensive. A forest plantation should reduce a drain of water and help to delay it in the soil that anyway will be the undoubted benefit.
