Cities and urban corridors are sites of intense human activity,…show more content…
Sources of urban air pollution maybe grouped according to their origin in industrial, residential and transport activities (Kojima & Lovei, 2001). Anthropogenic air pollution originates from a variety of sources, including households, vehicles, large stationary sources, small and medium size industries, agriculture and forest burning. Pollution from many of these sources is closely related to the production and consumption of energy, especially the combustion of fossil fuels. Traffic is the large contributor to fine particulate emissions (Kojima & Lovei,…show more content…
Over exploitation of open spaces, ever-increasing numbers of automobiles and demographic pressure have further aggravated the problem. There are various ways and means to mitigate the urban environmental pollution. Planting of trees and shrubs for abatement of pollution and improvement of environment is an effective way and well recognized throughout the world. Proper planning and planting scheme depending upon the magnitude and type of pollution, selection of pollution- tolerant and dust scavenging trees and shrubs should be done for bioremediation of urban environmental pollution. Pollution, the major problem in cities, is compounded by the fact that there is no exhaust for the polluted air to escape. Landscape architects can solve the pollution problems related to urban landscape by creating a micro-climate
