Africa’s Great Green Wall: Restoring Landscapes and Fighting the Sahara

The Great Green Wall initiative is recording gradual progress in its effort to restore degraded landscapes across the Sahel region of Africa. The project aims to combat desertification, reverse land degradation, and improve the livelihoods of millions of people living in one of the world’s most climate-vulnerable zones.

Launched by the African Union, the initiative seeks to create a mosaic of green and productive landscapes across the width of Africa. The primary objective is to restore 100 million hectares of currently degraded land by 2030, while simultaneously sequestering 250 million tonnes of carbon from the atmosphere.

The project spans a belt of countries in the Sahel, including Senegal, Mauritania, Mali, Burkina Faso, Niger, Nigeria, Chad, Sudan, Ethiopia, and Eritrea. By restoring the land, the initiative intends to create 10 million green jobs in rural areas, reducing the economic pressures that often drive migration and regional instability.

From a Wall of Trees to a Landscape Mosaic

While early descriptions of the project focused on a literal wall of trees stretching 8,000 kilometers from Senegal to Djibouti, the strategy has evolved into a more complex “mosaic” approach. This method emphasizes integrated landscape management rather than simple reforestation.

The current strategy incorporates a variety of sustainable land management practices tailored to local ecological conditions. This includes the implementation of agroforestry, where trees are integrated into agricultural crops to improve soil fertility and provide shade, as well as the use of water-harvesting techniques to maximize the utility of limited rainfall.

A central component of this progress is Farmer-Managed Natural Regeneration (FMNR). This technique involves the systematic regrowth and management of trees and shrubs from living tree stumps, roots, and seeds already present in the soil. Unlike planting new seedlings, which often have high failure rates in arid climates, FMNR leverages existing root systems to ensure higher survival rates for vegetation.

Impact on Livelihoods and Food Security

The restoration of land is directly tied to the economic stability of the Sahelian populations. As soil quality improves, agricultural yields increase, providing a more reliable food source for communities that have historically struggled with chronic food insecurity.

The initiative focuses on diversifying income streams for rural inhabitants. By planting fruit-bearing trees and developing non-timber forest products, such as gums and resins, local farmers and women’s cooperatives can access new markets. This economic diversification is designed to make communities more resilient to the erratic weather patterns caused by climate change.

The project also addresses the social dimensions of land degradation. By restoring communal grazing lands and water sources, the initiative seeks to reduce conflicts between sedentary farmers and nomadic herders, who often compete for dwindling fertile resources in the region.

Challenges to Implementation

Despite the gradual gains, the Great Green Wall faces significant operational hurdles. Political instability in the Sahel has hindered progress in several participating nations. Military coups and ongoing conflicts in countries such as Mali, Burkina Faso, and Niger have disrupted project coordination and limited the ability of international partners to monitor progress on the ground.

Funding remains a critical constraint. While the project has received pledges from the World Bank, the European Union, and various international climate funds, the actual disbursement of funds has often been slower than the pace of environmental degradation. The scale of the project requires sustained, long-term investment to move from localized successes to a continental impact.

Monitoring and verification also present a challenge. Tracking the restoration of millions of hectares across remote and insecure borders requires advanced satellite imagery and ground-level reporting, both of which are difficult to maintain consistently across all participating states.

Current Status and Long-Term Outlook

The Pan-African Agency of the Great Green Wall continues to coordinate the efforts of the member states to align their national strategies with the overall 2030 goals. The focus has shifted toward ensuring that restoration efforts are community-led, ensuring that the people living on the land have a direct stake in its preservation.

The project serves as a global model for large-scale ecosystem restoration. Its success depends not only on the biological act of planting trees but on the ability of African governments to maintain political stability and secure the necessary financial resources to support rural populations throughout the transition to a sustainable economy.
