“The availability and accessibility of food is constrained by the environments where people live, work and purchase goods, and the pathways which they use to traverse these. This recognition has given rise to innovative conceptual frameworks including “food environments” and “food deserts”. These concepts add a spatial dimension to food security research that could inform food systems governance. Although the concepts have expanded the understanding of food security in the global North, their application to the
South African context, and to value chains analysis, is still in its infancy. This paper introduces these frameworks and considers their utility in South African cities. The paper presents recent data emerging from case studies of local food geographies conducted by the African Food Security Urban Network (AFSUN). This research proceeded from recognising the importance of informal retail in South African urban food systems. The case studies mapped formal sector food retail outlets in urban Johannesburg,
correlating these with socio-economic data. Informal food processing and trade were also mapped in smaller research areas to explore food prevalence and diversity in the local geography and map the
spatial patterns of informal food outlets. These studies reveal that the distribution of supermarkets entrenches spatial inequalities and constrains access to food distributed through formal value chains.
The studies also reveal spatial and temporal patterns of informal food retail, which provides diverse food retail outlets clustered around public transport access points, along high traffic pedestrian routes, and distributed throughout residential spaces. Although healthy foods are available, unhealthy foods and
risky food environments are pervasive. These findings confirm that the concept of food deserts fails to reflect the diversity of food available and accessible through informal livelihoods and suggests that scalar network models of food geographies offer better conceptual frameworks.”
