With over half the world's population now living in urban environments, the transition to sustainable and regenerative cities has never been more urgent and important. Governance is at the heart of this challenge given that cities function as complex adaptive systems composed of diverse social-technical interactions. This presentation asks the question: How can place-based experimentation drive systemic innovation to advance sustainable cities?
Drawing on insights from 300,000 Streets and the Net Zero Precincts projects, our research employs systems thinking and design to develop and test new modes of urban governance. Through action research and deep stakeholder engagement, we identify how community-led initiatives across Melbourne’s streets and institutional support at a precinct scale can be scaffolded and coordinated to create centres of gravity that shift grassroots activity from the margins to the mainstream. The methodology includes ethnographic fieldwork, co-design workshops, transition management and living labs to understand how local aspirations can inform city-wide transformation. Key findings reveal that Melbourne’s streets and precincts are rich with latent potential for regeneration, but current governance structures often inhibit democratic participation and community agency. The erosion of trust between residents and decision-makers has led to a disconnect from place and each other. These two initiatives propose a responsive, multi-level, place-based framework that reconnects people with their streets, enabling them to co-create resilient, liveable cities. The potential impact of this work is significant: by positioning streets and precincts as the connective tissue of urban life, we can foster inclusive governance, accelerate climate action and build social cohesion. This multi-prong approach offers a transferable model for other cities seeking to transition toward sustainability through community empowerment, institutional embedding and systemic innovation.
