The Circumpolar North has been changing rapidly within the last decades, and the socioeconomic systems of the Eurasian Arctic and Siberia in particular have displayed the most dramatic changes. Here, anthropogenic drivers of environmental change such as migration and industrialization are added to climateinduced changes in the natural environment such as permafrost thawing and increased frequency of extreme events. Understanding and adapting to both types of changes are important to local and indigenous peoples in the Arctic and for the wider global community due to transboundary connectivity. As local and indigenous peoples, decision-makers and scientists perceive changes and impacts differently and often fail to communicate efficiently to respond to changes adequately, we convened a meeting of the three groups in Salekhard in 2017. The outcomes of the meeting include perceptions of how the three groups each perceive the main issues affecting health and well-being and recommendations for working together better.
A recent multidisciplinary compilation of studies on changes in the Siberian environment details how climate is changing faster than most places on Earth with exceptional warming in the north and increased aridity in the south. Impacts of these changes are rapid permafrost thaw and melt of glaciers, increased flooding, extreme weather events leading to sudden changes in biodiversity, increased forest fires, more insect pest outbreaks, and increased emissions of CO 2 and methane. These trends interact with sociological changes leading to land-use change, globalisation of diets, impaired health of Arctic Peoples, and challenges for transport. Local mitigation and adaptation measures are likely to be limited by a range of public perceptions of climate change that vary according to personal background. However, Siberia has the possibility through land surface feedbacks to amplify or suppress climate change impacts at potentially global levels. Based on the diverse studies presented in this Ambio Special Issue, we suggest ways forward for more sustainable environmental research and management.

This systematic review and meta-analysis based on PRISMA statements aimed to summarise the data on the chemical composition of reindeer meat depending on the region of the Rangifer tarandus. We searched SCOPUS, PubMed, Embase, CrossRef, Medline, Cochrane library, eLibrary, and CyberLeninka. A total of 3310 records published between January 1980 and December 2021 were screened. We identified 34 relevant studies conducted in Russia, Norway, the USA, Canada, and Finland for the synthesis. Overall, the consumption of reindeer meat reduces arterial hypertension and atherosclerosis due to many polyunsaturated fatty acids (linoleic, linolenic, arachidonic) and vitamin C, which balances lipid fractions. Venison is an effective means of preventing obesity and adapting to cold due to the content of a complete set of essential trace elements, amino acids, and even L-carnitine. The high content of vitamin C and microelements (iron, zinc, copper) in reindeer meat is likely to increase the body’s antioxidant defence against free radicals and help prevent chronic non-infectious diseases. Thus, venison is an essential component of the adaptation mechanism for the Arctic population.
Introduction. The nutrition of the Nenets in the Arctic zone of Western Siberia is mainly based on traditional products (raw (thermally unprocessed) local fish and venison), which is the most important factor of survival in the Arctic. Storing up food products for an extended period is not relevant for the Nenets. Climate change and industrial development in the Arctic primarily affect the seasonality of consumption. Changing the calendar of fish and venison harvesting leads to greater use of imported and canned local food, increasing the length of the periods when local food completely disappears from the diet of the Nenets. Material and methods. During the expeditions to the national villages of the Yamal-Nenets Autonomous Okrug, cross-sectional screening studies were performed, in which 985 Nenets people took part. Nutritional analysis was conducted using the questionnaire method based on an album of portions and dishes. Retrospective information was collected on the seasonality of consumption of reindeer products and local fisheries (the length of the period when unserved fish and venison are available). Results. The consumption of reindeer and river fishery products is seasonal. The duration of the season of venison consumption was from 150±14.0 to 180±21.0, and raw fish - from 120±14.0 to 200±21.0 days. Despite the high level of consuming reindeer products per season, the average annual consumption of venison by Nenets in the Arctic zone of Western Siberia was 240 g/day/person that is less than in the central regions of the Russian Federation and industrially developed countries. In the studied area, the average annual consumption of fish (171.5 g/day/person) is three times higher than the average consumption in the Russian Federation. However, increased consumption of traditional food is typically only during the season of fishing or slaughtering reindeer. The average annual consumption reduced; during the off-season, the share of easily digestible carbohydrates in the diet increased. Conclusion. The creation of fish and venison stocks in villages and their year-round sale to the population is a necessary step in ensuring the food security of the Nenets people.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
