Coastal environments in the Arctic are increasingly affected by the rapidly changing climate. Significant and complex impacts of atmospheric warming have been intensifying, with changes observed both in terrestrial and marine environments. Here, we describe the overview and highlight the study results of multidisciplinary research activities performed under the ArCS II project (Arctic Challenge for Sustainability II) in the Qaanaaq coastal region of northwestern Greenland. The Japanese Arctic projects GRENE-Arctic and ArCS have conducted research at this study site since 2012. In continuity with these previous efforts, field and satellite measurements were carried out to quantify glacier and ice sheet changes. Fish, marine mammals and seabirds, which are key natural resources to human livelihoods, were studied in collaboration with local fishermen and hunters to examine habitat use and clarify the potential responses of marine ecosystems to the changing environments. Greenlandic villages are also directly affected by the flooding of glacial streams and landslides, which were monitored to better understand the driving mechanisms and risks to Arctic societies in the future. Research was also carried out in Qaanaaq village to investigate waste management and housing conditions. The study results were shared with residents through workshops that took place in Qaanaaq and nearby smaller villages. Our results show that coastal environments in northwestern Greenland are changing wit...
