Sustain is a UK-based alliance of organisations campaigning for better food and farming — for practices that are healthy, fair, and environmentally sustainable. It brings together groups working on issues from school meals and food poverty to pesticide reduction, sustainable fishing, and local food economies, coordinating joint campaigns and policy advocacy. As a coalition it amplifies voices that would be quieter alone, giving community food projects and NGOs a shared platform in national debates. Its work includes public campaigns, briefings for policymakers, and awards that recognise good practice. For anyone interested in the politics of the food system in Britain, Sustain is one of the central civil-society actors.
