Analysing the Land Use Land cover by using Multi–Spectral Remote Sensing Data in Tehri Garhwal, Uttarakhand

Land use and land cover (LULC) changed drastically throughout the time frame, today there are various factors which is responsible for changes in agricultural land use, anthropogenic and natural factors both have reasons for it, anthropogenic factors like infrastructural development, agricultural activities, recreation activities play major role, natural factors like forest fires, climate change mainly responsible, The investigation studies in modifications in LULC, More than two decades, researcher prepared LULC maps with the assistance of multi-spectral remote sensing Landsat 5 series data used for preparing maps of 2001 and 2011, 2021 map created with Sentinel 2 series data, two decades maps of LULC gives picture about variations in land cover and use, 2001 taken as base year of study, LULC in mountainous regions of Tehri Garhwal different from plain regions, cropping pattern is different, agricultural productivity is different, Seven major LULC types (Crop land, Built Up Area, Forest cover, Water, Range land, Snow Cover and bare Grounds) built-up areas have steadily increased during the past 20 years, demonstrating substantial infrastructural development and urbanization, Crop land is consistently declining, snow cover continuing decline from 2001 to 2021 indicating signifies a move away from conventional agricultural uses, Planning for urbanization must integrate economic expansion with preservation of the environment., addressing the reduction in snow cover and its ripple consequences requires mitigation as well as adaptation measures, such as encouraging sustainable behaviours and renewable energy.
