The authors of Principles of Brownfield Regeneration argue that, compared to 'greenfields' - farmland, woodland, or pasture that have never been developed - brownfields offer a more sustainable land development choice. They believe that brownfields are central to a sustainable planning strategy, thwarting sprawl, preserving or regenerating open space, reducing greenhouse gas emissions, and reinvesting in urbanised areas. This is the first book to provide an accessible introduction to the design, policy, and technical issues related to brownfield redevelopment. After defining brownfields and advocating for their redevelopment, the book describes the steps for cleaning up a site and creating viable land for development or open space. Land use and design considerations are addressed in a separate chapter. Throughout, the authors draw on interviews with people involved in brownfield projects as well as on their own considerable expertise.
