Sustain is a “think and do” network, specialising in designing and building sustainable & healthy food systems. We work for the transition to a food system that supports flourishing communities, individuals and ecosystems. We give people, councils, and organisations the tools they need to help them become empowered food citizens, supporting healthy communities, people and ecosystems. Sustain emerged from the Food Alliance (2009-2014), where the Circles of Food methodology was developed, borrowing from Circles of Sustainability. We are based in Melbourne, Australia, and currently hosted by the William Angliss Institute. Sustain is a registered deductible gift recipient and Health Promotion charity.
