Regreening Koulikoro

Growing trees and restoring land to build the Great Green Wall.

The project

During this 2-year project, we partnered with Timberland to help them reach their goal of planting 50 million trees by 2025. The project started in January 2020 and finished in December 2021.

We worked with communities in the Koulikoro region of Mali to grow trees and re-green the land and contribute to the Great Green Wall movement. The trees we planted through this project are helping to improve the fertility of the soil and help crops to thrive, tackling food insecurity and poverty in the region.

Tree Aid also supported the establishment of community-based nurseries and reinforced local knowledge to plant trees across farmland and degraded communal land.  

Why was this project needed?

Mali is one of the poorest countries in the world, where most people rely on the land for food and income. But in a country which is already two-thirds desert, the effects of the climate crisis are making farming even more unpredictable.

The Koulikoro region of Mali has been particularly affected by droughts and deforestation. As a result, the land is rapidly losing its fertility and it is becoming harder for people to grow enough food.

Our impact

A total of 308,203 trees were planted in the project, exceeding the original goal of 255,000. In addition, 5,000 seedlings were planted by students from 50 schools through the '1 student, 1 tree' initiative.

714 hectares of severely degraded communal land have been completely closed off from all destructive activities such as livestock grazing and tree cutting, and training was provided to 2,000 lead farmers on tree planting, tree grafting, tree care and bush fire management. These farmers will be responsible for sharing their knowledge with the rest of the community.

Awareness campaigns have run throughout the communities to ensure buy-in – including through local radio shows. The project has also worked with municipal and traditional leadership structures to ensure support and sustainability for the project.
