Deeper Cityis the first major application of new thinking on 'deeper complexity', applied to grand challenges such as runaway urbanization, climate change and rising inequality. The author provides a new framework for the collective intelligence- the capacity for learning and synergy - in many-layered cities, technologies, economies, ecologies and political systems. The key is in synergistic mapping and design, which can move beyond smart 'winner-takes-all' competition, towards wiserhuman systems of cooperation where 'winners-are-all'. Forty distinct pathways 'from smart to wise' are mapped in Deeper Cityand presented for strategic action, ranging from local neighbourhoods to global finance. As an atlas of the future, and resource library of pathway mappings, this book expands on the author's previous work, City-Region 2020. From a decade of development and testing, Deeper Citycombines visual thinking with a narrative style and practical guidance. This book will be indispensable for those seeking a sustainable future - students, politicians, planners, systems designers, activists, engineers and researchers. A new postscript looks at how these methods can work with respect to the 2020 pandemic, and asks, 'How can we turn crisis towards transformation?'
