City-Region 2020 is one of the most wide-ranging investigations of sustainable development in any city or region in the world. Looking at the long term dynamics of a major conurbation, it follows from the Town & Country Planning Association's 'Planning for a Sustainable Environment', and goes far beyond short term 'greening' to explore fundamental trends and goals for the case study of Greater Manchester. It combines technical scenarios for land, energy and material flows, with lateral thinking on cultural trends and the third sector, and a practical package of methods and tools. The result is published by Earthscan as a demonstration of integrated long term planning, with methods and tools for any city or region in the developed world (author's summary)
