The emissions reductions from this project are produced by smallholder farmers - among 31 Malian farmers who have applied for a contract with Zanbal. To date, more than 400 farmers are expected to join in the coming years. The project design is certified The Gold Standard.
Zanbal is the Malian social business that organizes the exchange. The smallholder farmer captures 100 tons of CO2 by growing 100 fertilizer trees in a geo-referenced plot in 40 years. Zanbal is in charge of defining, with the smallholders, the financing plan and the expected return. Zanbal is also responsible for the Gold Standard certification of tCO2e emissions reductions.
Project impacts and benefits:
Each Malian smallholder famer receives 100 € a year for 20 years (2,000 €) for 100 trees grown and 100 tCO2 captured.
Once matured, fertilizer trees, which fix nitrogen from the air, raise minerals from the soil, and they have the unique feature of losing their leaves during the rainy season and thus they do not shade crops (species = Acacia albida = Faidherbia albida = balanzan). They generate 1,000 kg of yield of associated crops. They also produce 1,000 kg of pods consumed by ruminants, which fertilize the plot by their stay under the trees.
