Food accessibility of different socioeconomic groups in sub-Saharan African cities: a mixed-method analysis in Kampala, Uganda

Cities in sub-Saharan Africa are characterised by rapid urban sprawl, which has implications for urban food accessibility. Urban sprawl results in inefficient structures of cities, and is often related to patterns of socioeconomic segregation. An important research gap in food accessibility studies is that these local socioeconomic imbalances are not considered in broad-scale studies. This research analyses how the dimensions of food access (physical, social and economic) relate to the food insecurity and dietary diversity of inhabitants of different socioeconomic groups in the rapidly growing Greater Kampala Metropolitan Area (Uganda). We use the Food Insecurity Experience Scale and Household Dietary Diversity Score to assess the overall state of food consumption. To measure physical accessibility, we geographically map the formal food system potential. A radar chart was used to visualise the vulnerability of different socioeconomic groups within the city food system. The results show that more established urban dwellers experience different access vulnerabilities than newly migrated residents, depending on their income. Lower income groups compensate their limited economic accessibility by participating in food sharing networks. Obtaining a better understanding of the dimensions of urban food accessibility can aid stakeholders in the urban food system in their policy making processes towards a more food secure and sustainable future.
