Rapid urbanisation generates risks and opportunities for sustainable development. Urban policy and decision makers are challenged by the complexity of cities as social–ecological–technical systems. Consequently there is an increasing need for collaborative knowledge development that supports a whole-of-system view, and transformational change at multiple scales.

A roadmap describes the measures required to achieve goals and/or map future innovation opportunities. The three questions addressed by a comprehensive roadmap are: Where do we want to go?, Where are we now?, and How can we get there?
