The changing pattern of climate and weather and increasing human interference making the Himalaya more vulnerable towards geo hazards. We have witnessed a series of such events during last one decade at various locations in Himalaya. People in and outside Himalaya facing a number of serious issues that threaten the physical environment, biodiversity and their livelihoods due to such events. Along with anthropogenic factors the fragility and vulnerability aspects of Himalaya are the reasons for increased geo instability resulting in receiving extreme natural calamity. It is the Climate that varies from the foothills to valley regions to the highly elevated perpetual snow-clad mountain peaks that needs to be taken into consideration for a better understanding of monitoring the phenomenon of different geo hazards. For this a track of transition, extremity and events needs to be done in proper manner to mitigate the impact of these unforeseen events to physical and human environment.
Present study is aimed at a systematic and comprehensive framework of research and it's outcome to understand the geo hazards in Western Himalaya of India. Study comprises of the extreme events of Laddakh, Himachal Pradesh and Uttarakhand to explore physical sites, explain the mechanism, evaluate the impact and mitigation process. Work is based upon various events occurred during last 12 years in the region and physical site visit, verification, data collection and information compilation. The outcome of the study is a result of application of few RS GIS techniques to make is understandable to common people and researchers.
Study suggests that Climate change, construction of roads and other human activities, deforestation, biodiversity imbalance and livelihood shift for the last two decades are the changes responsible for hazards in the Himalayan regions.
