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.

This article provides a database of the local snow-measuring observations for three river basins in the south of Western Siberia, reviews the methodological peculiarities of the conduct of measurements, and compares the acquired data with the observations at weather stations and available satellite data (CGLS SWE). Observations were carried out in several stages over the period of ten years (2011-2021) in small river basins of Kuchuk, Kasmala, and Mayma Rivers, and reflect the transition from the West Siberian Plain to the Altai lowlands. Total of 25,000 measurements of the parameters of snow deposits (snow mass and snow storage) were made over the years. The database of snow measuring observations is accessible to public. The comparison with station and satellite data indicated significant variances, but also fairly good coherence in some reservoir basins. According to satellite data, the common to basins mean squared error of snow storages was 42.9 mm, which is slightly higher than the claimed by the product engineers (37.4 mm). The time-limited observation data on the permanent routes of weather stations demonstrated the mean squared error of snow storages of 43.5 mm. In winter period, the mean squared error of satellite data gradually increased to the period of maximum accumulation of snow in reservoir basins. Moreover, the errors of satellite data did not depend on the snowiness of the winter period; and most likely, are associated with the parameters of microstructure of the snow mass in separate seasons.

Snow Precipitation

Stable water isotopes in snowpack and snowfalls are widely used for understanding hydrological processes occurring in the seasonally snow-covered territories. The present study examines the main factors influencing changes of the initial stable water isotopes composition in the seasonal snow cover of the south of Western Siberia. Studies of the isotopic composition of snow precipitation and snow cover, as well as experiments with them, were carried out during two cold seasons of 2019–2021, and laser spectroscopy PICARRO L2130-i (WS-CRDS) was used for the determination of water isotope composition (δ18O and δD). The main changes in the isotopic composition of the snow cover layers in the studied region are associated with the existence of a vertical temperature gradient between the layers and with the penetration of soil moisture into the bottom layers in the absence of soil freezing. During the winter period, the sublimation from the top layer of snow is observed only at the moments of a sharp increase in the daily air temperature. At the end of winter, the contrast between day and night air temperatures determines the direction of the shift in the isotopic composition of the top layer of snow relative to the initial snow precipitation.

The Impact

Climate change represents a global challenge that impacts the environment, traditional lifestyle and health of the Indigenous Peoples in the Arctic zone of Western Siberia and threatens their food security. Reindeer are an important food source for this population since reindeer herding products are used as traditional nutrition and effective preventive means and remedies for adapting to the cold and geomagnetic activity in the High North. Longer off-season periods, high summer and winter temperatures, melting ice, and forest and tundra fires have a significant impact on the trampling and degradation of reindeer pastures. These effects may lead to massive reindeer losses and changes in the traditional diet of the Indigenous Peoples in the Arctic, which result in increases in the prevalence of respiratory diseases, overweight and hypertension. This study applied a multidisciplinary approach based on ecological and medical research methods with the inclusion of socioeconomic analysis. The primary sources included data on the longitudinal dynamics of air temperature as a climate change indicator and reindeer livestock populations (1936–2018), consumption of reindeer products and physiological impacts on the Yamal Indigenous population collected during expeditions to the Arctic zone of Western Siberia in 2012–2018.

The Impact

The purpose of this work is to review and analyze the main results of modern research on the impact of climate change on the agro-sphere of Ukraine. Results. Analysis of research has shown that the effects of climate change on the agro-sphere are already being felt today and will continue in the future. The observed climate changes in recent decades have already significantly affected the shift in the northern direction of all agro-climatic zones of Europe, including Ukraine. From the point of view of productivity of the agro-sphere of Ukraine, climate change will have both positive and negative consequences. The positives include: improving the conditions of formation and reducing the harvesting time of crop yields; the possibility of effective introduction of late varieties (hybrids), which require more thermal resources; improving the conditions for overwintering crops; increase the efficiency of fertilizer application. Model estimates of the impact of climate change on wheat yields in Ukraine mainly indicate the positive effects of global warming on yields in the medium term, but with an increase in the average annual temperature by 2 ° C above normal, grain yields are expected to decrease. The negative consequences of the impact of climate change on the agrosphere include: increased drought during the growing season; acceleration of humus decomposition in soils; deterioration of soil moisture in the southern regions; deterioration of grain quality and failure to ensure full vernalization of grain; increase in the number of pests, the spread of pathogens of plants and weeds due to favorable conditions for their overwintering; increase in wind and water erosion of the soil caused by an increase in droughts and extreme rainfall; increasing risks of freezing of winter crops due to lack of stable snow cover. Conclusions. Resource-saving agricultural technologies are of particular importance in the context of climate change. They include technologies such as no-till, strip-till, ridge-till, which make it possible to partially store and accumulate mulch on the soil surface, reduce the speed of the surface layer of air and contribute to better preservation of moisture accumulated during the autumn-winter period. And in determining the most effective ways and mechanisms to reduce weather risks for Ukrainian farmers, it is necessary to take into account the world practice of climate-smart technologies.

The Impact

Every aspect of human operations faces a wide range of risks, some of which can cause serious consequences. By the start of 21st century, mankind has recognized a new class of risks posed by climate change. It is obvious, that the global climate is changing, and will continue to change, in ways that affect the planning and day to day operations of businesses, government agencies and other organizations and institutions. The manifestations of climate change include but not limited to rising sea levels, increasing temperature, flooding, melting polar sea ice, adverse weather events (e.g. heatwaves, drought, and storms) and a rise in related problems (e.g. health and environmental). Assessing and managing climate risks represent one of the most challenging issues of today and for the future. The purpose of the risk modeling system discussed in this paper is to provide a framework and methodology to quantify risks caused by climate change, to facilitate estimates of the impact of climate change on various spheres of human activities and to compare eventual adaptation and risk mitigation strategies. The system integrates both physical climate system and economic models together with knowledge-based subsystem, which can help support proactive risk management. System structure and its main components are considered. Special attention is paid to climate risk assessment, management and hedging in the Arctic coastal areas.
