Pulse crops for sustainable farms in Sub-Saharan Africa

Food insecurity in sub-Saharan Africa is a problem affecting 153 million individuals (ca. 25%). This problem could be worsen by the ongoing soil degradation, being cause by the reduction of soil organic matter and insufficient nutrient supply. Over 75% of the agricultural land in Africa could be classified as degraded by 2020. This situation can compromise food production in sub-Saharan Africa, both quantitatively and qualitatively, and the sustainability of existing agricultural production systems. The use of fertilizer could revert this situation; however, Africa has almost no capacity to produce fertilizers (African fertilizers production facilities work mainly in blending fertilizers) and therefore fertilizers are produced elsewhere outside Africa and transported from long distances at great expenses. This situation grants to sub-Saharan Africa farmers only a very limited access to fertilizers, thus increasing the risk of soil degradation. Pulses have a long history in sub-Saharan Africa due to their multiple benefits.

Pulses, and legumes in general, can play an important role in agriculture because their ability to biologically fix atmospheric nitrogen and to enhance the biological turnover of phosphorous; thus they could become the cornerstone of sustainable

agriculture in Africa. In this sense, there is a body of literature that points to diversification of existing production systems; particularly legumes species, which provides critical environmental services, including soil erosion control and soil nutrient recapitalization. This publication is a review of some of the promising strategies to support pulses cultivation and utilization on smallholder farms in sub-Saharan Africa. The review is part of the legacy of the International Year of Pulses (IYP), which sought to recognize the contribution that pulses make to human well-being and the environment.
