Africa’s Great Green Wall

Can Africa’s Great Green Wall beat back the Sahara desert and reverse the degrading landscape? The ambitious 9 miles wide and 5000 miles long line of vegetation will stretch all the way from Dakar in the west to Djibouti in the east.

Thomas Fessy is in Senegal where the wall has already begun to evolve into a series of forests and garden communities. He meets the planners, planters, ecologists and local villagers to hear how its early progress is reversing years of poor land use, turning nomads back to farmers, empowering women and creating healthy ecosystems for rain fed agriculture.

But can it meet its ambition to stabilize an unstable region, reverse the growing trend of migration, fight the effects of climate change and ensure this big African dream doesn’t die in the sand?
