Urban Sprawl: Definitions, Data, Methods of Measurement, and Environmental Consequences

By Reza Banai and Thomas DePriest

Like sprawl itself, writing about sprawl is scattered in a vast multidisciplinary literature. In this paper we provide a map of what is increasingly known about urban sprawl in emerging literature. This review of progress includes four main parts—definition, data, methods of measurement, and environmental consequences of urban sprawl. The focus of this literature review is to determine whether the aforementioned parts are elements of a connected system in which progress in any one part reflects in others, thereby enhancing knowledge of urban sprawl’s environmental consequences through a cross-fertilization with progress in how sprawl is defined, data are used, and phenomena are measured. We conclude with a discussion of areas of further research that surmounts the shortcomings of a disconnected, epistemic (knowledge) system of definitions, data, and methods, and points toward an explanation of urban sprawl’s environmental consequences. The implications for the education of urban sustainability are noted.
