The Great Green Wall is an ambitious African-led project restoring 100 million hectares of degraded land across the Sahel region with an ambitious 8,000-km ecosystem restoration project to combat climate change
The African Union in 2007 launched an ambitious plan to fight climate change and land degradation across the continent. The Union named this project the Great Green Wall after the Great Wall of China.
The Green Wall right now spans across 11 core nations in the Sahel region of Africa and aims to restore about 100 million hectares of drylands by 2030.
It’s noteworthy that the local communities chose to deploy sustainable farming and native tree planting with the use of water harvesting techniques to revive the soil.
Let’s read more about this large scale ecological effort in Africa which is already addressing climate change along with securing food and jobs for millions of vulnerable residents.
Why Africa’s Sahel Region Needs The Great Green Wall Shield
The Sahel region of Africa sits on the southern part of the Sahara Desert and temperatures here rise 1.5 times faster when we compare it with the global average.
This rapid rise in temperature triggers Intense droughts.
It also ruins the fertility of the soil and thus triggers widespread poverty.
Due to these reasons communities were helplessly watching their ancestral farmlands turn into a barren wasteland. Then the Great Green Wall stepped in to reverse this environmental decline.
This 8000 km Wall of trees has brought vegetation back to the land. It has also initiated cool local climates and improved groundwater levels.
Healthy soil in the region now allows farmers to grow crops reliably again which directly reduces hunger and regional instability. This project protects both nature and human lives

From a Single Line of Trees to a Living Mosaic
The planners first simply envisioned this project as a continuous strip of trees. But they soon realised that a single line of trees would not survive the harsh climate.
So today the Great Green Wall initiative focuses on the restoration of a flexibly localised ecosystem.
Farmers are practising agroforestry which is mixing trees with traditional crops to shield plants from the blistering sun.
This approach creates a resilient mosaic of forests cum grasslands and productive farms across twenty nations
Progress and Targets for the 2030 Horizon
So far the progress report of the Wall of Trees is positive. The project thus sets monumental goals for the end of the decade. All the participating nations plan to capture 250 million tonnes of carbon dioxide from the atmosphere.
They also intend to create 10 million green jobs in rural areas to offer young people promising economic reasons to stay home
Recent updates from the UNCCD also show that workers have already successfully restored over 30 million hectares of land. While funding gaps and local conflicts present hurdles the movement continues to expand. It is proof enough that collective action can restore balance to the planet and heal our environment
