Analytical Review of Land Use Changes by Remote Sensing and GIS Techniques in District Gujrat, Pakistan

Abstract

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