The present study show an integrated approach of remote sensing and geographical Information System (GIS) for comparatively analysis of climate change and human intervention that is landuse/ cover dynamic of the region present in the lower Himalayas of the Uttarakhand state (Nainital district). Nainital is one of the famous tourist destination of India. This study is conducted with the help of two multi temporal images of Landsat 5 thematic mapper (TM) of year 2008 and another one is Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) of year 2018. From 2008 to 2018 significant change has been detected in land use/cover, NDWI and LST over a period of decades.The study reveals that Nainital city is expanding towards south- west direction and the study also reveals that as the climate change directly affect on vegetation and on surface water bodies present in the area. The climate data (land surface temperature) data shows the area under greater than 35 degree Celsius increased in 2018 as compared to 2008 data and there is decrease in rainfall in last decade. It also indicates that increase in temperature, decrease and erratic nature of rainfall, and decreased in area of surface water bodies and decrease in vegetation/ dense vegetation area etc. during last decades it impact on farming activities. The farming activities specially for crops which depends on snowfall and rainfall are affected and it directly and indirectly affect primary economic activity of local communities.
