Urban Sprawl means :
The increasing geographical spread of urban areas into areas that were not previously built up. (1) This urban form is often costly to service and has often led to socio-spatial fragmentation of cities. Additionally, sprawl into peri-urban areas has a negative impact on agricultural and natural land and systems. (2) Sprawl is a result of urban and commercial development coupled with growing economic prosperity. In many places in the world, there is also a traditional preference for suburban development going hand in hand with a preference for larger homes. This has led to a surge in energy use and dependence on motorized transport, as well as an overall increase in per capita GHG emissions. The number of personal vehicles grows much faster than the urban population, posing a negative impact on the environment and on infrastructure. Developing countries are increasingly affected by peri-urbanization. The resulting problems of this type of urbanization are manifold, and include intense pressures on resources, slum formation, lack of adequate services such as water and sanitation, poor planning, and degradation of farmland. They are of particular significance in developing countries, where planning regulations may be weak or weakly enforced, and result in areas with complex patterns of land tenure and land use.
