City visions represent shared, and often desirable, expectations about our urban futures. This book explores the history and evolution of city visions, placing them in the wider context of art, culture, science, foresight and urban theory. It highlights and critically reviews examples of city visions from around the world, contrasting their development and outlining the key benefits and challenges in planning such visions. The authors show how important it is to think about the future of cities in objective and strategic ways and by engaging with a range of stakeholders - something more important than ever as we look to visions of a sustainable future beyond the COVID-19 crisis.
