Rapid urbanization and infrastructural development in the Garhwal Himalaya have significantly altered the fragile geomorphic conditions, exacerbating the risk of landslides and related hazards. This study presents a comparative assessment of developmental activities between the years 2008 and 2018 in the Uttarkashi district, Garhwal Himalaya, using Geographic Information System (GIS) and remote sensing techniques. High-resolution satellite imagery and topographic maps were analyzed to delineate changes in land use, particularly focusing on residential, commercial, industrial, and road infrastructure. The spatial overlay of these developmental features with Landslide Hazard Zonation (LHZ) maps revealed a pronounced increase in built-up areas within high and very high susceptibility zones. Between 2008 and 2018, residential buildings increased by 954 units, commercial structures by 541, and major roads by 20 units, indicating rapid landscape modification. The findings highlight that nearly two-thirds of the total built-up area lies within high-risk zones, underscoring the need for stricter land-use planning and slope stabilization measures. This study provides crucial spatial insights for sustainable development and disaster mitigation planning in the seismically active and geomorphologically sensitive Garhwal Himalaya.
