ABSTRACT

 

This study is an attempt to analyze and emphasize the present condition of land use/land cover in Jhelum watershed of Kashmir valley in North western Himalayan environment. Land use/land cover determines the structure, functions and dynamics of present day landscapes. The extensive changes in land use/land cover dynamics observed in Jhelum River watershed have adversely affected the environment. The land use/land cover is under remarkable anthropogenic pressure. Rapid and erratic modifications of land use/land cover due to accelerated human activities, especially in fragile mountainous ecosystems like Kashmir valley have wider environmental impact. In the present study authors used IRS (Indian Remote sensing) LISS-III (Linear Imaging Self Scanning Sensor) (23m) images and Landsat-7 ETM (Enhanced Thematic Mapper) + C1 Level Image for extracting information on geomorphology, vegetation cover, Habitation, and Forest cover change analysis. Data have been collected for alternate years 1998,2000,2010,2014. SRTM (The Shuttle Radar Topography Mission) and ASTER (Advanced Spaceborn Thermal Emission and Reflection) G-DEM (Global Digital Elevation Model) were used for mapping water shed and river flow model. The study, carried out in Jhelum River basin of Jammu and Kashmir region is located between 320 17 and 370 45 N latitudes and 740 and 750 30 E longitudes. The comparative study and related results of LU/LC data for the years 2010, 2012 and 2014 derived from analysis of toposheets and satellite imagery interpretation indicates that increase in built-up area/rapid urbanization has decreased substantial amount of agriculture land, water spread area and forest area in study region. On the other hand, climate change has also played an important role in affecting the lu/lc occupancy in study area. Greater variability in trends of climatic cycle is observed more prominently in the study area. It is observed that the trend of annual and monthly rainfall and temperature statistics remains constant whereas in summers, the temperature increases highly which may cause unseasonal rainfall midway. Moreover, examination of the seasonal mean minimum temperature series has shown that the mean maximum temperature for winter and autumn has increased terribly and remaining warm throughout the year. Thus the all above climatic parameter have adversely affected the growth of seasonal crop production and forest cover in the region.
