<p>Based on the experience of a family farm in southwestern China, this article analyzes the forms of politicization related to the emergence of healthy food supply chains. By analyzing the role of farmers within an association that sells peasant food, this study shows how territorialized practices influence the demand for short food chains. The Association promotes social and environmental activity through the co-construction of a food system by the actors concerned, from production to consumption. It thus opposes the conventionalization of short supply chains promoted by educated elites for affluent consumers. The article examines what remains essentially political in the commercial interaction of short supply chains, despite an authoritarian context that restricts spaces for deliberation and capitalist transformations at the expense of village economies. The article is based on ethnographic fieldwork and participatory research in Guangxi with producers, market intermediaries, researchers, and NGO members. It develops the hypothesis that the collective activity built into the market interactions of short supply chains allows for the maintenance of a space for politicization and localized action, which is gradually being restricted by the demand for healthy food and the digitization of trade.</p>
