SPATIAL-TEMPORAL VARIATIONS OF NITROGEN DIOXIDEIN AND AROUND LAHORE METROPOLITAN AREAS USING “GIS”TECHNIQUES

Abstract

In developing countries the process of urbanization has an impact on land use patterns of a city. The cities are performing according to their environmental, social, cultural, and economic conditions. The economic and commercial activities of the cities are increasing due to accelerated population growth. The cities of Pakistan are facing environmental issues which are creating damages in air, soil, ground water. Transport sector in a country has direct impact on the deterioration of air quality and high growth rate in transport sector causes energy consumption and leads to the greenhouse gases emissions especially NO2in Lahore. The city of Lahore not yet started a regular air quality monitoring system. The data already available in the departments have highlightedthatit is not properly managed/shaped or mapped. A sustainable urban development in Lahore can only be achieved by managing land use, complete periodic study of air quality with weather variables and traffic management system of the hotspot areas.Thisstudyfocusseson spatial and temporal variations of NO2at selected locations in LMA. On the bases of results, the LMA area are classified into risk zones of the air pollutant speciallyNO2.
