Great Green Wall Project Challenges

The Sahara Desert is expanding due to climate change, threatening the Sahel region with desertification. The Great Green Wall initiative aims to combat this by restoring 100 million hectares of land through reforestation and sustainable practices. Despite challenges like funding and conflict, the project shows promise in improving local environments and livelihoods.
