Siberian environmental change: Synthesis of recent studies and opportunities for networking

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 CO2 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.

Changing diets and traditional lifestyle of Siberian Arctic Indigenous Peoples and effects on health and well-being

The diet of Indigenous Peoples of North-Western Siberia is characterized by a significant proportion of traditional foods. Eating local products provides a ready-made set of macro- and microelements necessary for life in the challenging conditions of the Arctic. Currently, high consumption of traditional foods is typical in the season of fishing or reindeer slaughter, while out of season the consumption of easily digestible carbohydrates increases. Due to climate change, seasonal fishing and traditional migration routes are disrupted and, therefore, the consumption of traditional foods is decreasing. During 5 years of expeditions, we performed a cross-sectional screening of 985 Indigenous People from three districts of the Yamal-Nenets Autonomous Okrug. We analyzed the seasonality of acquisition and consumption of local reindeer and fish products and studied the traditional food storage among 90 Indigenous fishermen and hunters, who exploit cryostorage. As diet affects health, we studied the benefits of local food. The duration of the consumption season is decreasing and therefore the amount of consumption of local food is decreasing as well. This has adverse effects on health with increasing hypertension dissemination. The creation of stocks of fish and reindeer meat in villages and their year-round sale to the population is a necessary step for ensuring the food security and health of the inhabitants in the region.

Perspectives of climate change: A comparison of scientific understanding and local interpretations by different Western Siberian communities

We present a study of social effects of climate change as experienced by local communities, based on field research and analysis in Western Siberia, from southern taiga to tundra. The results of field anthropological research reveal different attitudes of local residents to climate change. We compare the key trends of climate change with the perspectives of local residents, based on memories, subjective experiences, and local environmental knowledge. Our results highlight a significant divergence of the subjective assessments of residents from objective data on the dynamics of changes in certain environmental elements. We explore how the human subjective perception of natural processes, their consequences and impacts, are influenced by such factors as: type of settlement, age, gender, level of education and how collective stereotypes and judgments merge information in attitude formation. We also address the need to reconcile observed climate change impacts and perceptions to enable decision-makers to engage more constructively with the local population to develop and implement adaptation.

Improving dialogue among researchers, local and indigenous peoples and decision-makers to address issues of climate change in the North

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 climate-induced 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.
