This study was carried out to reveal the characteristics of climate-influenced landscape in the tundra with the case study of Cambridge Bay in Canada. This study was conducted for a part of regional study to understand the lifestyle of Arctic and Inuit people. Traditional knowledge and practices of indigenous peoples are emerged as adaptation issues to the changes of tundra environment.

The contents of the study are descriptions on the climate-influenced landscape, utilizing interview, which mainly focused on buildings, infrastructure, and transportation. In building construction, they are applying the building method considering permafrost. The infrastructures are also adapting to extreme weather conditions, such as supplying water and sewage disposal by trucks instead of water and sewage systems using pipes. The way of transport has been changed from dog-sleds to modern snowmobiles and ATVs. The use of ATV is on the rise as the period of time without snow is getting longer.
