Those concerned with growth and development at national or local levels must pay significantly more attention to the physical structure of urban settings which house many of the leading sectors of the economies of nations. These metropolitan areas must retain the flexibility necessary to meet the needs of an ever-changing mix of activities. Structural, environmental, and economic concerns are brought together to help the reader better understand the problems and identify solutions. This work will be of interest to those economists, environmentalists, sociologists, and practitioners concerned with growth, change, and the environment in urban settings, as well as planning and development agencies in Third World settings.
