Sustainability has become the key challenge for urban planners, housing and infrastructure policy makers. Citizens are increasingly encouraged to live more compactly; in denser urban developments, to use less water and other natural resources and to choose public transport. While councils, government agencies and private business invest in a broad range of promotions offering discounts on sustainable products and services, uptake has been slow and the impacts marginal at a time when environmental stresses suggest that we must act fast. This book examines this pressing problem in a holistic way, discussing broad-scale sustainability policies and programmes for achieving sustainable urban futures. It brings together academics and practitioners to analyse the complexity and interdependence of principles, models, processes and practices of sustainability in a range of integrated sectors as well as the establishment and maintenance of sustainable physical infrastructure in cities.
