Abstract:
defining feature of many of the world’s cities is an outward expansion far beyond formal administrative boundaries, largely propelled by the use of the automobile, poor urban and regional planning and land speculation. A large proportion of cities both from developed and developing countries have high consuming suburban expansion patterns which often extend to even further peripheries. Cities need to accommodate new and thriving urban functions such as transportation routes, etc. as they expand.
The physical growth of urban areas is disproportionate in relation to population growth, and this result in land consumption that is less efficient in many forms. This type of growth violate every premise of sustainability that an urban area could be judged by including impacting on the environment and causing other negative social and economic consequences such as increasing spatial inequalities and lessening of economies of agglomeration.
