Will trees alleviate hunger in Africa?

摘要

This paper discusses in brief the challenges in food production in Africa. Also, the paper explores the agroforestry systems, in particular, those aimed at addressing soil health problems, such as fertilizer tree systems, as components of integrated soil fertility management systems. Further, the paper establishes that in the face of poor and risky incentives, the integrated soil fertility management approach seems the best way forward, because it promotes the use of a range of nutrient sources. Fertilizer tree systems are an important option, given their low cost and proven ability to generate significant changes in soil health.Digital Object Identifier http://dx.doi.org/10.1525/bio.2012.62.2.3
