What will it take to restore 100 million hectares of land in Africa?

The challenge is massive, but so is the promise. Healing 100 million hectares of degraded and deforested land in Africa will bring countless benefits: fresh air and water, food and energy —the very stuff of survival. It will also build people’s climate resilience, and contribute in a big way to global climate change mitigation goals.

Land restoration aims to bring back ecological functionality to degraded ecosystems. It can be achieved by introducing or allowing trees to grow on landscapes and using sustainable land management techniques such as terracing steep hillsides, minimizing tillage and building structures to stop soil erosion. Curbing free-grazing of livestock and managing water also support land restoration. Read more. . .

While raising crop yields, African thorn tree Faidherbia albida captures large amounts of carbon

A large, old Faidherbia albida tree with a metre-plus diameter stored the equivalent of the CO2 emitted by 8 cars over one year. These useful trees play an important role in carbon sequestration, a critical part of the effort to reduce greenhouse gas emissions linked to climate change.

People in many areas of Africa gain numerous benefits from the leaves, branches and trunks of the dryland thorn tree Faidherbia albida. Read more. . .

More money and less risk for African eco-farmers

A Greenpeace study in Malawi and Kenya has revealed that chemically-intensive farming hurts the bottom line of small-scale farmers; agroecological farming is more profitable.

Agroecology refers to a suite of sustainable farming practices that use few or no external chemical inputs. The approaches, often rooted in traditional farming techniques, include sustainable land management, water harvesting, agroforestry, biological control of pests and weeds, intercropping, organic farming, permaculture, and several others.
