Intermittent food deserts. Exploring the spatiotemporal dimension of the urban fresh food access in Chilean citie

Abstract

Food deserts in Chile present a singularity in the context of the Global South. Unlike other countries where food security is mainly achieved through informal trade, in Chile, weekly streets markets is the structural system providing fresh food. Supermarkets complement spatially and functionally street markets. Both systems and their temporal operation makes that the Chilean food deserts main characteristic is their intermittency. The purpose of this research is to analyze the Chilean food deserts to contrast them with the predominant North and Global South discourses and position the Chilean case internationally. Specifically, this article looks to analyze the importance of the spatiotemporal dimension in food access studies where a healthy diet depends on systems other than supermarkets characterized by intermittent operation over week. For this purpose, this article takes the Metropolitan Area of Concepcion as case. First, the research identifies the location and the socioeconomic groups associated with the different degrees of access from a static perspective based on the spatial distribution of supermarkets and street markets. Then, the dynamic analysis introduces the time dimension to reveal the variability of access patterns and the impact on vulnerable groups.

The intermittency of the food deserts positions Chile as halfway between the Global South and North models. The particularity of this model is that intermittently and regularly provides a healthy food environment within food deserts. Additionaly, it has the potential to be planned for overcoming structural inequalities in spatial fresh food access
