Abstract
There is growing recognition that radical, long-term change is required to address inherent issues in the industrial food system. New principles and practices are needed to create fair, sustainable and healthy food approaches. Actions for degrowth often begin at the grassroots, grounded in everyday actions that promote just and sustainable alternatives. However, limited resources often result in actions with bounded geographical reach and lifespan. Formal efforts to address food insecurity and sustainability by governments, NGOs and corporations have benefits, offering legitimacy and visibility by providing resources, institutionalisation and legislation. However, large-scale approaches often lack transversality, overlooking important local concerns and needs. This chapter explores multilevel governance approaches that bring together bottom-up and top-down approaches to foster engaged and enduring food alternatives. Strategies of cross-sector platforms, methods of convergence and the role of municipalities are examined in two projects: the Portuguese rights to food nutrition network AlimentAção! that promotes sustainable and healthy local food projects, and EdiCitNet, a food sustainability network that supports the uptake of innovative and inclusive urban food practices. This chapter contributes to sustainable food literature and practice by examining key junctures across different levels of governance to sustain healthy and just degrowth alternatives for transformative change.
