Towards a New Urban Health Science

The intensity and range of health challenges that people in cities are facing has increased in recent years. This is due in part to a failure to adequately adapt and respond to emergent and expanding global systemic risks, but also to a still-limited understanding of the profound impacts of complexity on urban health. While complexity science is increasingly embraced by the health and urban sciences, it has yet to be functionally incorporated into urban health research, policy, and practice. Accelerating urbanization in a context of escalating environmental constraints will require deeper engagement with complexity, yet also, paradoxically, much swifter, more effective, and more risk-averse decision-making. Meeting these demands will require adopting a science, policy and practice style which is integrative, inclusive, collaborative, systemic, fast, and frugal. We propose transformational shifts in scientific methodology, epistemological and ontological stances, types of rationality, and governance to shift researchers, policymakers, practitioners, and citizens towards a new, complexity-informed science of urban health.
