Urban Sustainability e-bog

More than half the world's population currently lives in urban areas, and virtually all of the world's population growth over the next three decades is expected to be in cities. What impact will this growth have on the environment? What can we do now to pave the way for resource longevity? Sustainability has received considerable attention in recent years, though conceptions of the term remain vague. Using a wide array of cities around the globe as case studies, this timely book explores the varying nature of global urban-environmental stresses and the complexities involved in defining sustainability policies. Working with six core themes, the editor examines the past, present, and future of urban sustainability within local, national, and global contexts.
