Urbanization refers to an increase in population and industrialization within settlements. In India, uncontrolled urbanization is rapidly degrading the environment and causing problems. As urban populations grow, impacts on the atmosphere, land, water, and biosphere include increased air pollution, erosion, flooding, and habitat modification. Municipal solid waste generation is also increasing in metropolitan cities, where slum populations and motor vehicle usage have tripled over the past decade. To improve conditions, priorities must be given to reducing vehicular pollution, waste generation, and improving urban planning.
