Within HCI, sustainable HCI and human-food-interaction have developed as a response. We argue, nevertheless, that food practices as a social activity remain relatively under-examined, and further that sustainable food practices hinge on communal activity. We present the results of action-oriented research with a grassroots movement committed to sustainable food practices at a local, communal level, thereby demonstrating the role of ICT in making food resource sharing a viable practice. We suggest that the current focus on food sharing might usefully be supplemented by attention to food resource sharing, an approach that aligns with a paradigm shift from surplus to abundance. We argue for a design that aims to encourage food resource sharing at a local level but that also has wider ramifications. These “glocal” endeavors recognize the complexity of prosumption practices and foster aspirations for “deep change” in food systems.enCC BY-NCGrassrootsSustainabilityContext (archaeology)BusinessResource (disambiguation)ScarcityFood systemsInformation and Communications TechnologyPolitical scienceFood securityEconomicsEcologyGeographyAgricultureArticle10.1145/3589957
