12-Country Coalition: Building the Great Green Wall of Africa
The clock is ticking for the collaborative creation of a living green wall to span nearly 5,000 miles across the African continent, designed to slow or even stop the relentless spread of desertification. The scope of this unique organic building project is unprecedented, as is its urgency.
China took over 1,000 years to construct their Great Wall, but scientists believe Africa may only have a few decades before the Sahara Desert engulfs more than two thirds of its arable land. Hence the Great Green Wall of the Sahara, set to stretch from coast to coast, west to east.
