This field report summarizes an international interdisciplinary research project in Saidy, Republic of Sakha, in the Russian Far East. The aim of the research was to study ecological adaptations of communities in northern Sakha, combining methods of anthropology, archaeology, and ecology. Most indigenous communities in this region demonstrate a high level of self-organization—for example, forbidding sales of alcohol and transforming drinking to a hidden activity. These communities are actively engaged in the informal economy where officially unemployed people run informal grocery stores, hunting, and transport enterprises. Local practices are a mixture of Evenki and Sakha culture with emphasis on individualism. People in these communities are not nostalgic about Sovietera collective farms—something that is unusual in Siberia—and see current life as better than that in the Soviet era.
