What drives food insecurity in southern Africa? a meta-analysis of household economy studies

Abstract

Food insecurity, and the factors that determine it, are experienced at the level of the household and the individual. Food insecurity is also spatially varied across regions. In this paper meta-analysis is used to synthesize 49 household economy local-level studies that focus on community-level livelihood strategies to identify drivers of food insecurity in southern Africa. The results reveal entrenched cycles of vulnerability in southern Africa's food insecure communities, where socio-economic issues feature prominently. The direct causes of inadequate food access are poverty, environmental stressors and conflict: these account for 50% of the identified indirect drivers of food insecurity. Meta-analysis is used to suggest the common processes behind food insecurity that take specific forms in particular communities. The findings underscore the need to understand the multiple social and political dimensions of food insecurity, such as the breakdown in social capital associated with poverty, conflict and HIV/AIDS, that run deeper than environmental constraints to food production.
