Book excerpt: The discourse around derelict, former industrial and military sites has grown in recent years. This interest is not only theoretical, and landscape professionals are taking new approaches to the design and development of these sites. This book examines the varied ways in which the histories and qualities of these derelict sites are reimagined in the transformed landscape and considers how such approaches can reveal the dramatic changes that have been wrought on these places over a relatively short time scale. It discusses these issues with reference to eleven sites from the UK, Germany, the USA, Australia and China, focusing specifically on how designers incorporate evidence of landscape change, both cultural and natural. There has been little research into how these developed landscapes are perceived by visitors and local residents. This book examines how the tangible material traces of pastness are interpreted by the visitor and the impact of the intangible elements - hidden traces, experiences and memories. The book draws together theory in the field and implications for practice in landscape architecture and concludes with an examination of how different approaches to revealing and reimagining change can affect the future management of the site.
