All over the world, fertile land is vanishing, swallowed up by the desert. Africa is particularly hard-hit.
In a century, the Sahara has moved south by 250 km, over a 6,000 km front.

Today, a decisive and stubborn battle is being led against desertification. The Pan-African Great Green Wall Project, to stop drying up of the Sahel, was launched in 2005. It meant to reforest a 15 km wide band, from Djibouti to the north of Senegal, over a length of 7,600 km.

But so far, only Senegal has really committed itself to this huge project.
