The Himalaya is experiencing rapid climate change that is likely to significantly impact local ecosystems, biodiversity, agriculture and human well-being. However, the scientific community has been slow to examine the extent and consequences of climate change. Local communities have been
coping with environmental change since millennia. Thus they often have considerable knowledge about environmental change and means to cope with its consequences. We (a) examined the perceptions of local communities about climate change and its impacts on ecosystems, biodiversity, agri-
culture and livelihoods in the Kangchenjunga Himalayas region; (b) analysed the consistency of perceptions across geographical regions, and (c) assessed the conformity between local perceptions and scientific evidence. Our study is based on surveys conducted in 576 households, focus
group discussions, key informant surveys and direct observations. The results show that people in the Kangchenjunga Himalayas region have considerable knowledge of climate change and its effects on the weather, ecosystems, biodiversity and agriculture. These perceptions are consistent
across the region and conform to scientific findings.
