[1] Because trees remove carbon dioxide from the air as they grow, tree planting can be used to help limit climate ...
The use of Faidherbia albida in Malawi and Zambia has resulted in a doubling or even tripling of maize yields. [3] As part of evergreen agriculture, use of fertilizer trees is proposed as a means to improve food security. Niger has more than 4.8 million hectares of predominantly Faidherbia agroforests, while Zambia has 300,000 hectares. [3]
