IMPACT OF URBANIZATION ON GREEN COVER OF LUDHIANA DISTRICT USING REMOTE SENSING AND GIS

With the growth of population, urbanization increases, which leads to an improper development in any urban area. Impact of urbanization on green cover of Ludhiana district using Remote Sensing and GIS has been analyzed to study the status of land use/land cover this district. The mapping of wasteland of Ludhiana district also analyzed by using Survey of India (SOI) Toposheets and LISS-III data (2006 and 2012) of Ludhiana district through Arc GIS 10 and ERDAS Imagine 9.2 software. The area under land use categories such as built-up, water, forest, plantation, agriculture and wasteland were determined. The area of Ludhiana district under wasteland and fallow land is 3263.95 ha in 2012. The study shows that the built-up area of Ludhiana urban center in Ludhiana district has become 8 times than it was in 1970. Based upon the analysis of World View-II data for the year 2014 of Ludhiana urban center, it was observed that the area under built-up is 76.92 % and under agriculture only 13.9 %. It has been observed that the population of Ludhiana urban center has increased from 4,01,176 in 1970 to 17,44,650 in 2012. It is expected that in year 2030, area of Ludhiana urban center will increase from 14198 ha to 18692.2 ha.Keywords: Urbanization, Green Cover, Land Use/ Land Cover, Remote Sensing and GIS
