“A 7,000 km barrier is being built along the footsteps of the Sahara to stop the desert expanding. The Great Green Wall project started in 2007 in Senegal, along with 10 countries in Africa to combat the effects of climate change. Al Jazeera’s Nicolas Haque reports from Widou, deep in the Sahel.”
The Great Green Wall initiative is composed of 11 countries that are cooperating together to combat the physical and human geographic characteristics that make the Sahel one of the more vulnerable ecosystems in the world. This swath running through Africa is the transition zone where tropical Africa meets the Sahara. The Sahel is susceptible to drought, overgrazing, land degradation and desertification. These issues of resource management and land use transcend international borders so this “Green Wall” was created with the intent to protect the environment, landscapes and people of the Sahel from desert encroachment (the shorter, social media friendly version of this video is available here).
