This large tree-planting project stretches across roughly 6,000 miles of terrain at the southern edge of the Sahara desert, a region known as the Sahel. The region was once a lush oasis of greenery and foliage back in the 1970s, but the combined forces of population growth, unsustainable land management, and climate change turned the area into a barren and degraded swath of land.
Already, over 5 million hectares of degraded land has been restored in Nigeria using drought-resistant trees. By-products of the restored landscape include many groundwater wells refilled with drinking water, rural towns with additional food supplies, and new sources of work and income for villagers, thanks to the need for tree maintenance.
