主　　题：Climate Change Trend analysis Resource-quadrant Vulnerability Adaptation Central Himalaya 

摘      要：The Central Himalayan region is vulnerable to the adverse effects of climate change and characterized by regional climatic *** livelihood of the mountain communities across the Himalaya is at risk owing to the consequences of variable precipitation *** exists limited empirical research on precipitation variability due to inadequate hydro-meteorological stations at highaltitude *** study uses a novel methodology which integrates precipitation variability with resource sensitivity over the three verticals of Central Himalaya:Himadri,Himachal and Shivaliks and across four major river basins:Yamuna,Upper Ganga,Ghaghar and *** magnitude of the significant precipitation trends was estimated through time series analysis at a 95%confidence *** assess the sensitivity of natural resources(forest,water and land)and human resources,fourteen mountain-specific indicators were identified which captured resource index using data standardization and principal component ***’s slope and Resource index were plotted in a 2D Cartesian coordinate to draw precipitation-resource quadrants with their effective coverage area:High Precipitation and Scarce Resources(35.92%);Low Precipitation and Abundant Resources(30.10%);Low Precipitation and Scarce Resources(22.33%)and High Precipitation and Abundant Resources(11.65%).This helped in developing quadrant-specific adaptation strategies under regional variability of *** methodology and the research findings will certainly assist water experts,resource managers and policy makers to strengthen adaptive capacity and improve the resilience of vulnerable communities across Himalaya.
