This study is about the change of Inuit traditional culture. Inuit has their specific culture due to the Arctic’s harsh environment. But recently, because of the climate change and newcomers, traditional culture has changed. Hunting, the base of Inuit’s traditional culture decreased and was getting hard. And shelter and transportation for hunting has been modified. According to the change of hunting, food and adoption culture also changed. Inuit is in a situation to consume junk food and processed food instead of fresh food. Those food induce many problems to Inuit including health. And Inuit trade the food, not share. It means the community spirit weakened. Reduction of the importance of IQ (Inuit Qaujimajatuqangit) and the role of the senior also contributes to the weakening of community spirit. Inuit adopt non-Inuit child and adopt the child according to the law. It makes Inuit difficult to adopt child. As a result, climate change and newcomers makes today’s Inuit culture. Therefore, we have to know climate change and newcomers to understand the culture of the Arctic and residents.

The aim of this research is to analyze the level of food insecurity of Inuit in the area of Nunavut territory in Canada. As a result, we were able to find out the following facts. First, nearly half of them felt hungry due to lack of food as of 2018. Second, the food situation was getting worse year by year. In the four years from 2014 to 2018, the growth rate of food insecurity households reached 22.0%. Third, proportion of children under 18 who lived in food insecure households reached 78.7%. Starving children had low self-esteem, suffered from depression and had a very high suicide rate. Fourth, most of Inuit’s food tables were filled with store-bought foods, rather than country foods. Fifth, the food sovereignty of Inuit community was seriously threatened with local capacity of self-sufficiency being low, market-dependent being high, and political exclusion from the policy decision being severe. Two things needed to be kept in mind in order to solve this Inuit’s food insecurity efficiently. First, in addition to environmental factors such as climate change, food issues are interconnected and affected by socioeconomic, cultural and policy factors. Second, policy intervention in the food issues should be centered on the Inuit party in accordance with human rights and food sovereignty perspectives.

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. During august 2018, we interviewed local residents and experts at a field survey in Cambridge Bay, Nunavut, Canada. 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.
