Project Led by the African Union Aims to Halt the Advance of the Sahara, Restore Degraded Lands, and Generate Green Jobs in One of the Most Vulnerable Regions on the Planet
One of the largest environmental initiatives in the world is advancing on the African continent, combining climate goals with large-scale social impact. The Great Green Wall stretches approximately 8,000 kilometers, from the Atlantic Ocean to the Red Sea, traversing the Sahel with the goal of halting the advance of the Sahara Desert and restoring degraded areas.
The African Union officially launched the project in 2007, in partnership with the United Nations Convention to Combat Desertification (UNCCD). Since then, the program has established clear targets for 2030 and consolidated one of the largest global strategies to combat desertification.
Environmental and Social Goals by 2030
From the beginning, the participating countries defined measurable objectives to guide actions in the Sahel. The project aims to restore 100 million hectares of degraded land, sequester 250 million tons of carbon, and create 10 million green jobs in the region.

While scientists test giant balls on the seabed, a startup wants to sink concrete and steel tanks held by cages filled with stones up to 700 meters deep to transform compressed air into an invisible underwater battery.

Former NASA engineer transforms drones into “seed helicopters” capable of firing 300 balls per minute, targeting degraded areas with half-meter precision, and planting up to 40 million trees per year in a new race for aerial reforestation.

Brazil deploys drones to scatter seeds on nearly inaccessible slopes and attempts to transform degraded hills into forests with aerial planting up to 100 times faster, in a green offensive launched in Rio de Janeiro.

Second half of June brings more intense cold, polar air mass, and above-average rainfall in Brazil
Although the name suggests a continuous barrier of trees, the coordinators have redefined the model over the years. Currently, countries implement a mosaic of environmental interventions adapted to the ecological and social conditions of each territory.
Participating Countries and Implemented Actions
The initiative includes Senegal, Mauritania, Mali, Burkina Faso, Niger, Nigeria, Chad, Sudan, Eritrea, Ethiopia, and Djibouti. Each country executes actions such as reforestation of native vegetation, recovery of degraded pastures, and sustainable land management, always adjusting strategies to their climatic and productive characteristics.
This decentralized approach allows nations to adopt solutions compatible with their local realities while maintaining a common focus on land restoration and strengthening vulnerable communities.
Climate Challenges in the Sahel
The Sahel faces recurring droughts, rising average temperatures, and irregular rainfall, factors that reduce agricultural productivity and increase food insecurity. About 250 million people live in areas affected by environmental degradation in this part of the African continent.
In light of this scenario, governments and institutions consider the restoration of degraded lands an essential strategy to reduce social vulnerabilities, improve economic stability, and strengthen climate resilience.
Progress and International Funding
Since 2007, countries have reported the restoration of tens of millions of hectares, although numbers vary depending on the calculation methodology used. In 2021, international partners announced financial commitments of approximately €19 billion to accelerate the actions planned through 2030.
These resources expand the scale of interventions and strengthen coordination among participating countries, under the institutional monitoring of the African Union and the UNCCD.
An Integrated Long-Term Strategy
By integrating environmental recovery, carbon capture, and the generation of green jobs, the Great Green Wall consolidates itself as a strategy for climate adaptation and sustainable development. With targets set until 2030, the project maintains focus on land recovery and improving living conditions in the Sahel.
Faced with growing climate challenges and pressure on natural resources, the success of these goals could redefine the environmental and social future of the African region.
Do you believe that continental initiatives like this can become global benchmarks in combating desertification?
