Success factors for land and water management in Africa

At present, large expanses of land in rural Africa are degraded as a result of over extraction of trees for timber, firewood and charcoal. The problem is exacerbated by poor crop and animal husbandry practices, such as growing...

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...
