The aim of this paper is to advance our understanding of the complex material arrangements involved in the formation of AFNs by applying the concept of market infrastructure and turning our attention to the process of infrastructuring. Based on an ethnographic study of REKO rings, a network of local food markets, we show how disparate elements, e.g. digital interfaces, parking locations, and Swish (an electronic payment system), are interconnected and configured to form the REKO ring market infrastructure patchwork – an infrastructure made by linking together previously unrelated elements and re-purposing them. We then demonstrate how this patchwork infrastructure enables the formation of market actors, coordination of the market actors’ activities, and the qualification and valuation of foods, thereby making the exchange of alternative food possible. Our analysis of infrastructure patchworking illustrates a different type of infrastructure-making resulting in a temporary and fragile infrastructure which, despite its instability, enables exchange. Drawing on this analysis we argue that the potential of AFNs to take form and impact contemporary modes of food provisioning cannot be understood without exploring the process of infrastructuring.
