Global Value Chain Participation and Food Security in Sub-Saharan Africa: A Sector Analysis
Global Value Chain Participation and Food Security in Sub-Saharan Africa: A Sector Analysis

Summary/Abstract: This article analyses the effect of participation in global value chains on food security in the region, with a focus on a sectoral analysis of value chains. Using panel data from 26 countries in sub-Saharan Africa over the period 2008-2022 and a dynamic model estimated by the two-stage GMM method, the results obtained reveal that overall participation in value chains, both upstream and downstream, has a positive and significant effect on food security as a whole. However, they do not guarantee the stability of the food supply. In contrast, sectoral value chains reduce the average protein supply, reduce the variability of per capita food supply, decrease the share of energy intake from cereals, roots, and tubers, as well as agricultural value added per worker. Based on these results, the authorities should promote trade policies aimed at strengthening integration into regional value chains while emphasising local processing of products to improve the stability of food supply.
