(i) Urban Sprawl: Urban sprawl is unchecked spreading of a city or its suburbs. It often involves the construction of residential and commercial buildings in rural areas or otherwise undeveloped land at the outskirts of the city. Almost all the cities grow at the expense of surrounding agricultural land, thereby reducing the scope for agricultural expansion. Most residents of typical urban sprawl neighborhoods live in single-family homes and commute by car to workplaces in the city. The term Urban Sprawl is generally used with negative connotation because people sprawling in neighborhoods tend to drive more than those who don’t. Urban Sprawl is sometimes associated with increased air pollution. Moreover, at the initial stage, the suburbs grow along the major roads radiating from the town because of their accessibility, but soon the demand for Suburban homes increases and the land between the settlements is also covered by buildings so the new roads are to be constructed for the accessibility. (ii) Conurbation: A large densely populated Urban Sprawl formed by the growth and coalescence of individual towns and cities. Small towns and villages within the commanding distance of major cities are developed for residential use. In this way, towns keep on growing continuously and in some areas, the suburbs of a number of neighboring towns may coalesce to form continuous urban areas known as ‘Conurbation’. Big cities like Delhi, Kolkata and Mumbai along with their suburban towns are good examples of Conurbation.
