Urbanization study with land use/land cover change detection for the environmental impact on climate change using remote sensing and GIS technology (a case study of Udupi Taluk, Karnataka state, India)

Urbanization is a phenomenon with unprecedented population growth coupled with unplanned developmental activities which exerted heavy pressure on land and the resources surrounding them, leading to serious environmental problems. Identification and analysis of land-use/land-cover change in advance along with the study of built up area growth would help in effective infrastructure planning and resource management Udupi and its surroundings are experiencing unprecedented urbanization in recent times due to concentrated developmental resulted in the increase in population and consequent pressure on infrastructure, natural resources and ultimately giving rise to increase in built up area which causes a plethora of serious challenges such as climate change, enhanced greenhouse gases emissions, urban heat Island effects, etc. This research aims to evaluate the use of various satellite data for indicating built up area growth in urban areas of Udupi Taluk during the years 2000, 2006 and 2010 with an attempt to analyze contribution of change in land cover types for urbanization growth which causes temperature variation using Geoinformation technology.
