African leaders want to restore 100 million hectares of degraded land. They launched the Great Green Wall initiative back in 2007. The ambitious project spans 8,000 kilometers from Senegal to Djibouti.
Fighting Climate Vulnerability
This massive living structure targets the highly vulnerable Sahel region. Drought and climate change severely damage the soil there. Millions of people depend entirely on this land for farming.
Land degradation causes intense community conflict over scarce water and grazing rights.
An Integrated Mosaic Approach
The project uses an integrated ecosystem management approach. Communities plant trees and regenerate natural vegetation together. They also build smart rainwater harvesting systems.
The initiative set three massive targets for 2030. Leaders want to sequester 250 million tons of carbon. They also plan to create 10 million new green jobs. World leaders pledged billions of dollars to support this vision.
Overcoming Modern Challenges
However, physical progress remains very slow on the ground. Dry weather and hungry cattle kill many young seedlings. Ongoing armed conflicts also destroy landscapes and delay restoration efforts.
Local community farming approaches show the best results so far. Farmers protect existing root systems instead of clearing land for new trees.
