A REVIEW OF LITERATURE ON URBAN SPRAWL: ASSESSMENT OF FACTORS AND CAUSES

Abstract

Urban sprawl is a broad research topic in urban studies. Thus far, the debate on the causes and consequences of urban sprawl has not led to a widely accepted interpretative framework. This paper attempt to review publications on urban sprawl factors and causes extracted from two largest scientific databases namely Scopus and ScienceDirect. The time of publication was set from 1996 to 2015 with 20 years’ gap. The citation-based approach analysis was use to provide better vision regarding this topic where the journal articles are selected by using identified keywords from wide-ranging fields that cover built environment, geography, planning, architecture, engineering, economics, transportation, health, social and spatial technologies.

Subsequently, the factor and causes of urban sprawl were extracted from each publication and reviewed. The findings are presented in different categories including (i) socio-demographic, (ii) economic, (iii) political, (iv) physical, (v) environment, and (vi) transportation, pertinent to the formation of urban sprawl. The findings from this paper contribute in defining urban sprawl based on its factor and causes which cover broader context of built environment. The future improvement includes developing land use geospatial indices based on the outcome of this paper.
