The Beninese capital, Cotonou, lies below sea level. As a result, it experiences regular flooding and is on the front line of the risks posed by climate change. The city is also Benin’s main economic hub, and is aiming to meet these climate challenges head on. The “green lung” project includes plans to create more than 83 hectares of new green spaces, helping to filter polluting gases and increase the capacity of the land to absorb water during floods. In addition, the “green lung” would also provide local residents with a new area for leisure and eco-tourism.
