How does the great green wall help people in the Sahel adapt to the changes caused by desertification?
One example of a large-scale adaptation is the Great Green Wall (GGW), a proposal for a continuous band of trees stretching across the Sahel to reduce desertification by moderating temperatures, wind speeds and soil erosion, while increasing local microclimate humidity for agriculture [16,17,18,19,20,21].
What are the physical characteristics of the Sahel?
The Sahel is a narrow band of semi-arid land that forms a transition zone between the Sahara to the north and the savannas to the south. It is made up of flat, barren plains that stretch roughly 5,400 kilometers (3,300 miles) across Africa, from Senegal to Sudan.
What type of grassland is the Sahel?

Why is the Sahel unstable?
What are the biggest challenges in the Sahel? Armed conflict, economic insecurity, and the adverse effects of climate change are some of the biggest challenges affecting the region. This, in turn, has increased local competition for natural resources and threatens to exacerbate conflict and instability in the region.
What is the purpose of the Great Green Wall?
The Great Green wall is growing vegetation and restoring a band of land from Senegal to Djibouti to help boost food security, improve health, and create thousands of new jobs and income opportunities for the communities living there.
How is the Great Green Wall helping the environment?
The Great Green Wall initiative aims to restore land, sequester carbon and create jobs in some of the poorest communities in the world, where climate change is hitting the hardest.
Which countries lie in the Sahel?
Commonly, the Sahel stretches from Senegal on the Atlantic coast, through parts of Mauritania, Mali, Burkina Faso, Niger, Nigeria, Chad and Sudan to Eritrea on the Red Sea coast.
Which countries are part of Sahel?
Burkina Faso, Cameroon, Chad, The Gambia, Guinea Mauritania, Mali, Niger, Nigeria and Senegal. The support plan highlights the enormous opportunities in the Sahel and its vast assets in natural resources, energy, tourism and culture.
What kind of vegetation is in the Sahel?
Sahel Savanna. This savanna is known for its desert vegetation. The annual rainfall is poor and the wet season lasts 3 to 4 months, the grasses in this region are extremely short. Some of the plants in this zone include Ngibbi, Acacia raddiana, Leptadenia, and the African myrrh.
Why are there so many vegetation belts in Nigeria?
Vegetation usually depends on the climate zones of the country. Vegetation belts in Nigeria reflect the tight link between the vegetation and the country’s climate: Below there is the map of Nigeria showing vegetation belts.
Are there any tsetse flies in the Sahel savanna?
Relative to the dryness of the climate, there is no tsetse fly here. The main characteristic of Sahel savanna is desert vegetation. The annual precipitation is poor, and the wet season lasts 3 to 4 months, so the vegetation of this zone is rare and the present grasses are extremely short.
What kind of vegetation is there in Nigeria?
In this vegetation zone such plants as Ngibbi, Acacia raddiana, Leptadenia, and African myrrh are growing. The Montane zone is situated in high-mountain areas. Montane vegetation in Nigeria (mountain and plateaus vegetation) is not very developed due to the reason of low average temperatures and the significant impact of animals and man.
