摘      要：The Himalayas hailed as the‘water towers of the world’feed many perennial rivers which form the lifeline of the Indian *** change induced rising global temperatures and changing rainfall patterns are currently threatening the glaciers that feed the *** combination of these factors is causing water stresses to a part of the world which is usually considered water *** there are some large-scale studies done in the Himalayas,regional analysis of changing rainfall patterns and their impacts on vegetation and agriculture is *** we focus on the Indian state of Sikkim located in the Eastern Himalayas to evaluate these issues using mixed *** use satellite data from PERSIANN and MODIS to characterise the regional rainfall,vegetation,and surface temperature trends between 2001 and *** the analysis shows overall declining rainfall trends across most land cover classes,the trends in temperature are mostly positive for the period of study,with winter Land Surface Temperature(LST)values showing the largest area with marginally significant(p0.1)positive *** contrast,such patterns are not observed for ***,the interviews corroborate that even agriculture is impacted,implying that the trends continue at finer spatial scales *** lack of government support for adaptation and mitigation is also lamented placing the communities at a precarious position to continuing climate change.
