Urban planning is deeply implicated in both the planetary crisis of climate change and the personal crises of unhealthy lifestyles. Worldwide health issues such as obesity, mental illness, growing health inequalities and climate vulnerability cannot be solved solely by medicines but also by tackling the social, economic and environmental determinants. In a time when unhealthy and unsustainable conditions are being built into the physical fabric of cities, a new awareness and strategy is urgently needed to putting health and well-being at the heart of planning. The Routledge Handbook of Planning for Health and Well-being authoritatively and comprehensively integrates health into planning, strengthening the hands of those who argue and plan for healthy environments. With contributions from international leaders in the field, the Handbook of Planning for Health and Well-being provides context, philosophy, research, processes, and tools of experienced practitioners through case studies from four continents.
