Book excerpt: Since the 1970s, cities world-wide have been witness to radical de-industrialisation. Manufacturing was considered incompatible with urban life and was actively pushed out. As economies have grown, public officials and developers have instinctively shifted their priorities to short-term, high-yielding land uses such as offices, retail space and housing. Inner-city growth from New York to London and even Seoul have generally come at the expense of land uses such as manufacturing or logistics. Despite the odds, manufacturing is not in terminal decay in western cities. On the contrary, it is at the opening of a new chapter. Urban manufacturing can help cities to be more innovative, circular, inclusive and resilient. Recently, with increasing interest in the circular economy, with cleaner and more compact technology, with more progressive building codes for mixed use, with increasing awareness of the impacts of social inequality and with a clearer understanding of the value chains between the trade of material and immaterial goods, cities across the world are realising that manufacturing has an important place in the 21st century urban economy. While both enthusiasm for making is increasing and the value of manufacturing is becoming increasingly evident in cities, the topic remains extremely complex and challenging to manage. This book attempts to shed light on the ways manufacturing can address urban challenges, it exposes constraints for the manufacturing sector and provides fifty patterns for working with urban manufacturing. This book has been written as a manual to help politicians, public authorities, planners, designers and community organisations to be able to plan, discuss and collaborate by developing more productive urban manufacturing. The book is split into two parts. "
