POPULATION EXPLOSION, RESOURCE EXTRACTION AND ITS IMPACT ON THE URBAN ENVIRONMENT: A CASE STUDY OF KOLKATA METROPOLITAN AREA

Lakshmi SIVARAMAKRISHNAN

Abstract


Population explosion in the cities has a direct impact on the space, environment and quality of life. The growing population in cities consumes more resources and generates more waste. The expansion of urban areas is reflected over space in the form of increase of built up area and more concentration of population draws more and more resources from with in and the surrounding areas to satisfy its needs.In the past the size and the economic base of the city was limited and the cities ecological footprint remained relatively local, but today’s context is completely different from the past. Recently most of the megacities of the world particularly in the developing countries are under the phase of rapid expansion, globalization and development. The city’s population as a result bears the capacity to draw resources from far beyond its immediate region and have increasingly appropriated the carrying capacity of the rural region, with little apparent regard for the environment.Kolkata is one of the mega cities of the world, experiencing the huge population pressure. In this paper an attempt has been made to quantify the resources used by the Kolkata Metropolitan Area (KMA) and assess its impact with respect to the supply and demand.
