In these uncertain times of continuing climate change impact and the recent global pandemic, it is now more important than ever that we look long-term and provide the right tools for people to decide what sort of future they want for their cities across the world. ‘Urban futures’ thinking is based on the notion that we need a practical and formal framework to imagine what our cities could and should be like to live, work and play in, in the long term; how they will operate; what infrastructure is needed; and how governance systems will be required to help shape them and ensure their resilience. The book explores the history and evolution of city visions, placing them in the wider context of art, science, culture and urban theory. Drawing on a wide range of sources, including the authors’ own research of urban change, the book examines the rationale and development of city visions, and why they are now so important. To do this, the book places city visioning in the context of urban and regional planning and the emergence of ‘city foresight’, which is a set of futures-based techniques and methods to identify how cities might evolve into the future. The book highlights and critically reviews examples of city visions from around the world, contrasting their development, and outlining the key benefits and challenges in developing such visions. This is set within the wider context of the policy and practice implications of city foresight and city visions.
