Food security impacts of industrial crop production in sub-Saharan Africa: a systematic review of the impact mechanisms

A number of industrial crops have been promoted in sub-Saharan Africa (SSA) to meet a range of policy objectives including economic growth, rural development, agricultural modernization and energy security. The food security impacts of industrial crop production have received extensive policyattention and have been widely discussed in the academic literature. There is, however, an overall lack of a clear understanding of these impacts due to thelarge diversity of industrial crops, and their varied modes of production, expansion areas, and impact mechanisms. This systematic review synthesizes theavailable knowledge on the interface of industrial crops and food security in SSA. In particular we identify key patterns with how different industrial cropsand impact mechanisms are represented and studied in the current literature, and how they intersect to affect food security. The current literature isfragmented, as most studies focus on single or small subsets of crops and impact mechanisms. Most studies capture mechanisms related to food access andavailability, rather than to food utilization and stability. A clustering analysis identified the main literature clusters that combine mechanisms related to foodavailability, access to food, and environmental impact. The overall analysis presented in this systematic review allowed us to identify priority policy andpractice domains that need to be targeted in order to improve the food security outcomes of industrial crop production in SSA.
