Assessment of changes in land use and land cover through remote sensing and GIS is very important and keyanalysis. Urbanization has been continued by the rapid growth in the world economy so; it is the key study withregards to agriculture and urbanization. The aim of this study is to determine the loss of agriculture land and effects ofincreasing urbanization on surface temperature. For urban temperature impact analysis, distinctive time series ofLandsat images have been chosen. Temporal analysis for different time series shows the decrease in agriculture landand increase in built up area. Urbanization increased the temperature up to 20C. Positive correlation is found betweenbuilt-up area and temperature and negative correlation is found between green spaces and temperature. Unplannedurban sprawl and lack of proper irrigation system according to population are major problems in study area. Recentstudy will be helpful for decision makers to develop the sustainable environment policy in future.
