Senegal is spearheading a 12-nation effort to plant a 7,775km Great Green Wall of Africa to minimise the Sahara Desert’s destructive expansion.
The desert is second only to Antarctica in size and, according to Atlas Obscura, the UN estimates that “by 2025, two thirds of Africa’s arable land will be covered in Saharan sand.”
Planting began in 2008 and now there is 530km across Northern Senegal, which has cost the Senegalese government $6 million, but the benefits are already being felt.
Not only will this project ultimately prevent vast destruction of farmland, it will also provide jobs, tourism and generate media attention for impoverished communities in the area.
