Metropolitan Metamorphosis: Understanding Urban Expansion and Its Environmental Impacts

Abstract

An urban area's land use and cover often indicate various anthropocentric and physical two-dimensional land uses. In an urban region, building up residential and commercial sectors takes up the majority of the land. The rapid expansion of urban populations and residential areas has significantly transformed urban regions' LULC. Consequently, several factors combine to determine the extent to which a city's residential, commercial, and transportation regions, as well as its municipal area, population, and the number of settlements, undergo changes in land use and cover within the urban area. Nevertheless, in an urban environment, the factors that exert the most significant influence on the swift growth of the population and residential areas have led to alterations in land utilization and coverage, as well as the replacement of urban land utilization by urban dwellers.

Urban sprawl, often known as urban growth, is the unplanned or unwanted growth of a metropolis into the surrounding rural regions at the expense of the quality of the urban environment. This occurs as a result of factors such as high population pressure, low land prices, improved infrastructure, rising standards of living, a lack of urban planning, lower tax rates, and others. The repercussions of these expansions mostly include altered land uses, the resulting growth in traffic and public infrastructure, health and environmental problems, and altered social dynamics.
