Reconstruction of the fire frequency in the area of the Kulikovo Battlefield Museum Reserve (Upper Don Basin, Central Russian Upland) over the last 4000 years was carried out on the basis of macrocharcoal analysis (study of macroscopic charcoal particles with a linear size greater than 100 μm) of the peat core from the Podkosmovsky bog, which received the status of a specially protected natural area in 2013. The results of macroscopic charcoal analysis were compared with published quantitative reconstructions of forest cover and vegetation dynamics in the region, palynological data and archaeological material. The results of the study showed low fire activity in the area of the Kulikovo Battlefield between 4000 and 1500 cal (calibrated) years BP. According to the results of pollen analysis, the study area belonged to the forest-steppe vegetation zone during this period. The mosaic of plant cover included patches of deciduous pine forests, floodplain alder forests and grassland steppes on dry slopes. The forest cover of the area was 30–40% and reached 45% at about 2700 cal years BP, when the climate cooled and humidity increased. From 1500 cal years BP, the rate of charcoal accumulation in the peat deposit of the Podkosmosky bog gradually increased. The highest frequency of forest fires and the highest charcoal accumulation rates in peat were found for the period 900–300 cal years BP. The relationship between the periods of increased charcoal influx and climatic changes in the Late Holocene has not been established, but there is a clear correspondence between the interval of increased charcoal accumulation in peat and the stages of human activity in the region, confirmed by numerous archaeological finds. The decrease in forest cover in the study area to 15–20% over the same period and the abundance of anthropogenic pollen indicators in the pollen assemblages indicate an increase in human impact on the vegetation.
The article is devoted to the preliminary results of the study of the Kulikovo section (Sambian Peninsula, Kaliningrad oblast, Russian Federation), where deposits of one of the Late Pleistocene palaeobasins are exposed. The uniqueness of the section is due to its good preservation: while most of the postglacial basins that existed along the Baltic coast were subsequently destroyed during the Holocene marine transgressions and regressions, the deposits of the Kulikovo section, represented by silt with peat interlayers, provide an opportunity for a detailed study of the palaeoenvironment of the southeastern Baltic during the Middle to Younger Dryas (~14200–12500 cal BP). For the first time in the Baltic region, this type of deposits has been studied by microbiomorphic analysis. The aim of the analysis was to evaluate the informative potential of the method in relation to Late Glacial palaeobasin deposits and to obtain additional local data on Late Glacial vegetation and environment. The first phase of the study of the section showed the high informative value of the method. Data were obtained on the microbiomorphic composition of the Late Glacial water sediments. It includes 4 main categories of microbiomorphs: phytoliths, diatom shells, sponge spicules and plant detritus. Fe-rich spherules were also detected in the sediments. The analysis provided information on the plant communities surrounding the paleobasin, represented by reed communities, meadow and forest vegetation, including coniferous trees. The latter is an important point in the discussion about the presence of trees in the ice-free areas. A repeated change in hydrological conditions in the adjacent area was also noted, expressed in a change in the flow rate of the basin. Further study of the Fe-rich nodules in the Kulikovo sediments is important with regard to “impact events” and their role in the dynamics of the Late Glacial environment.
This article attempts to illustrate current approaches to the study of religious phenomena using the landscape framework. The authors identify similarities and differences in the interpretations of the most common terms used in foreign research to describe religion. The article shows that their semantic difference is mainly determined by their use as tools of either cultural geography or social anthropology. In particular, cultural geography focuses on the material objects of cultural landscapes and their geographical distribution, while social anthropology highlights specific features of people’s religious discourse and practices and analyses social processes that shape the modern world landscape. The term religious landscape can be used in the following ways, depending on how it is operationalized. First, it refers to the totality of material objects associated with religion. Secondly, it refers to the places where rituals take place. Finally, it refers to the territory in which followers of particular religious traditions live. The term religioscape implies a situation of conflict or complementary interaction between followers of different religions sharing the same space. Sacred landscape is sometimes applied as a synonym for the term religious landscape meaning a set of religious material objects. Sometimes it means a complex of natural places or objects of worship (mountains, hills, swamps, and others) that provides a general framework for various individual religious landscapes within it. The term sacroscape refers to the historically formed material manifestations of religiosity influencing both contemporary people and earth’s surface. The term spiritual landscape has several basic meanings. On the one hand, it is used as a synonym for religious landscape or sacred landscape. Secondly, it serves as a broader, generalizing term to describe all aspects of human interaction (ideas, objects, practices) with the supersensible world. Finally, the term spiritual landscape refers to spaces of not only ritual but also everyday practices.
On the territory of the Valdaisky National Park (Novgorod oblast) the analysis of invasions of alien species of vascular plants was carried out. The risk of invasion of alien species into natural ecosystems was assessed, considering the history of land use in the region, current nature management practices, and the ongoing development of transport infrastructure in the area. Since 2005, annual monitoring studies have been carried out using standard geobotanical methods along existing, modernized, and new linear structures in the Park’s territory and buffer zone. It has been shown that the forest–field–meadow structure of the vegetation cover, which has developed over the centuries, and the composition of the Park’s flora have proved to be quite resistant to the invasions. The composition and value of the invasive component in the flora of the National Park is 18% (133 species from 42 families). At the same time, the role of transport infrastructure in the spread of alien species is obvious. About 40–50% of the invasive flora (about 50–70 species) is limited to railways and roads, and their composition can determine the vector of spread—from the south-east and south to the north and north-west. In order to reduce the risk of invasion of alien vascular plant species and to preserve the unique native floristic complex, strict regulations are required for the development of transport infrastructure in the National Park.
Drylands are subject to degradation processes caused by natural and anthropogenic factors. Among the latter, agricultural activities stand out in terms of the scale and duration of their impacts worldwide. These processes are exacerbated in transboundary areas with different socioeconomic and environmental management institutions. We propose the ecological-landscape paradigm of agricultural land management, which aims to achieve sustainable development of transboundary territories as a single socio-ecological system, while respecting environmental standards and landscape resilience to agricultural pressures. This approach was applied to the dry steppe landscapes of the Russian-Kazakh transboundary area. It was found that 75% of the study area is occupied by low-stable landscapes; unstable to agricultural impacts – 17%; relatively stable – only 8% of the territory. The conservation strategy is proposed for landscapes unstable to agricultural impact and unsuitable for involvement in agricultural turnover due to their environmental, water and soil protection functions. The adaptation strategy is developed for landscapes with low stability, which should be used as farmland with a high proportion of perennial grasses and natural fodder by carrying out the necessary agricultural and recreational works. The development strategy with a grain-fallow soil protection system is most suitable for relatively stable landscapes. These strategies make it possible to find a compromise between the intensive use of dryland farmland and its conservation, and to apply uniform management tools in cross-border areas.
The paper discusses the features of the transformation of the structure of the water balance in the dark coniferous forests of the Yenisey Ridge, disturbed by logging. Questions of evapotranspiration dynamics are considered, considering reforestation successions in the cut areas. Based on the use of satellite data (MOD16A2), the change in evapotranspiration was analyzed considering the disturbance of the forest cover in the watershed. Against the background of the general dependence of evapotranspiration on meteorological parameters, the results showed that at the basin level, the variation in evapotranspiration depends on the accumulative effect of forest cover disturbance in the watershed. The ranking of felled areas, considering the regenerative-age dynamics of the vegetation cover, made it possible to assess the contribution of various stages of the reforestation process to the total evaporation in the Suhoy Pit River basin, and to reveal how the ratio of logging sites of the current year to the areas of already afforested cutting areas affects the amount of total evaporation. Studies have shown that if less than 2% of the total watershed area is deforested, then the logging does not cause major change in evapotranspiration and river runoff.
The study expands the possibilities of developing health tourism and terrain cure in Yuzhno-Sakhalinsk, Russia. There is a growing demand for domestic tourism, but the most famous tourist destinations are full. In this case, the development of other tourist destinations is relevant. Research into the landscape and climatic potential of the Susunai Ridge in Yuzhno-Sakhalinsk for the creation of the “Vos’merka” terrain cure route revealed an unusual combination of recreational landscape elements (2.48 points) with favourable mountain orography (2.83 points) and rich flora, valuable phytorecourses (2.5 points), high landscape and aesthetic quality of natural views (2 points), moderate bioclimatic mode of the area in terms of loads (2.16 points), unique on purity of the surface atmosphere and environmental ecological conditions (2.6 points), which integratively provide prospects for the development of summer and winter types of health tourism. When comparing heterogeneous indices of bioclimate and recreational landscape, we applied the method of scoring qualitative attributes used in resortology and recreational geography.
The article analyzes the change of climatic conditions in the Northwest of Russia, including the characteristics of dangerous hydrometeorological events (cold and heat waves, strong winds, extreme rainfall, snowfall, ice-frost deposits, hail) and slow climatic changes (increase in the number of days with the transition of air temperature through 0°С, coastal abrasion) in connection with their negative impact on terrestrial ecosystems. It was found that the influence of meteorological and climatic factors on terrestrial ecosystems is most pronounced in the northern part of the studied region, especially on the coast of the Barents Sea. Towards the south, the values of all indicators gradually decrease, and their structure changes. In the northern part of the study area (Murmansk and Arkhangelsk oblasts, the Nenets Autonomous Okrug), phenomena associated with strong winds and intensive ice-frost deposition, which contribute to the formation of an ice crust on the Earth’s surface, prevail. As one moves away from the coast, severe frost is observed more often (Komi Republic). In the center and south of the region, heavy rainfall, severe frost, and intense heat are the most frequent, resulting in a high fire hazard. The study carried out the ranking of the subjects of the Northwestern Federal District according to the degree of intensity of this process. Comprehensive assessments of the negative impact of changing climatic conditions on terrestrial ecosystems can be used to make decisions on the development of a strategy for environmental security of the regions of the Russian Federation.
The historical-geographical development of Bosnia and Herzegovina (BH) in the area of the fusion of Western and Eastern Christian civilizations and the Orient resulted in ethnic and religious heterogeneity, occasional political crises and ethnic conflicts that shaped the cultural identity and character of the entire development. BH was separated from the Yugoslav community in the conditions of the civil war. After the war in 1995, a complex administrative-territorial organization of the new state was established, based on the ethnic and religious affiliation of the population. At the same time, the transition of the socialist social system took place, as well as other geopolitical processes and social changes in the Western Balkans initiated by globalization. The paper focuses on cultural disintegration and changes in urban identity and development of cities through the analysis of the six largest urban centers as indicators of social changes in BH. The results of the analysis suggest that there has been a cultural differentiation of society, which is reflected in changes in the ethnic and religious structure of the population and their spatial distribution. Economic stagnation and depopulation of urban centers, as a consequence of the civil war and social reforms, were confirmed by a comparative analysis of statistical indicators of economic and demographic development. Cultural changes were determined by relevant scientific methods and approaches: historical-geographical method, comparative analysis of statistics of demographic indicators and changes in spatial distribution, ethnic and religious structure of the population, and economic changes by analysis of employment in sectors of the economy. The scientific results of previously published papers devoted to some of the mentioned problems, primarily economic development and population dynamics in BH and its large cities, were also taken into account. In this paper, social changes are observed through the cause-and-effect relationships of geopolitical and cultural processes (political, economic and cultural disintegration), social and economic reforms (ownership transition and deindustrialization) and their manifestations on cultural identity and the development of urban centers.
Network analysis of the Russian timber industry was based on the information about timber transactions between Russian companies in 2020. The data were collected from the Unified State Automated Information System Accounting Timber and Transactions with It. The method of graph clustering was developed. The first step is clustering of the hole graph by Leiden algorithm. The second step is drawing of each Leiden created cluster in abstract space using Fruchterman–Reingold layout and extraction of clusters from layout using meanshift algorithm. Such approach helped us to divide many Leiden-created clusters into components. This algorithm has a problem of resolution limit. It tends to combine some medium and small clusters into large ones. Also, a special method was developed to limit the uncertainty of clustering – both Leiden algorithm and Fruchterman–Reingold layout are non-deterministic algorithms. Wood trade clusters vary in size and content. They are rather autonomous. The average share of intra-cluster trade is 89%. The modularity score of our partition is 0.863. Each cluster has been described using open sources from the Internet. The content of the clusters does not contradict the logic of the wood industry processes. The clusters create rather compact areas on the map – wood trade regions. Their borders often overlap with existing administrative boundaries. Five types of network structure of clusters were defined: vertical monocentric, vertical polycentric, horizontal, dendritic, simple. There are three factors of clustering in wood industry of Russia: production chains (4 types – pulp, plywood, lumber, chipboard chains), demand chains (redistribution of raw material between manufacturers within the cluster, accumulation of wood volumes for some enterprises outside the cluster, wood trade between traders within the cluster), common holder. We have shown that existing approaches to cluster detection based on location quotients often misrepresent economic networks.
The paleogeographic study of one of the large Medieval settlements of the Jin Empire (1115–1234) in the Primorye was carried out in order to analyze the minor climatic rhythm during the settlement of a large river valley. New data on the chronology of the settlement were obtained using radiocarbon dating of charcoal and tephrostratigraphy. It was established that the territory began to be developed by the Krounovskaya culture (4th century BC to the 3rd century AD) under relatively dry conditions associated with a decrease in the summer monsoon intensity. In the 10th century the humidity increased sharply. The peak of warming occurred in the 11th century. At this time Medieval settlement appeared here, that existed before the construction of the fortress. The layers of this settlement lie under the ramparts. The study of pollen and diatoms in the cultural layers has allowed us to determine the characteristics of the environment during the Jurchen period (12th–13th centuries). Radiocarbon dating of the humus shows that the cultural layers contain redeposited organogenic material, which provides information on the pre-Jurchen environment. It has been established that significant changes in the natural steppe landscapes occurred in the early Middle Ages. Pollen data show signs of agriculture and other economic activities, including the plants’ cultivation, the development of ruderal plants and apophytes, as well as spores of pathogenic fungi. During the development of the territory in the Middle Ages, the main risks were associated with severe floods. Layers of loams found among the cultural layers indicate the repeated flooding of the fortress. Bioindicators of severe floods are allochthonous diatoms, represented by species that lived in the aquatic environment.
This paper presents the characteristics and comparison of subfossil pollen spectra of modern plant communities in the altitudinal zones of the Northern Sikhote-Alin and the Southern Sikhote-Alin, using the cases of the Tordoki-Yani Mountain (absolute altitude 2090 m) and Oblachnaya Mountain (absolute altitude 1858 m). All pollen spectra from high mountains reflect the forests caused by long-distance transport of tree pollen. Due to the abundance of Picea pollen, the pollen spectra of the mountain tundra and upper part of the subalpine belts of the Northern Sikhote-Alin correspond to the most common type of vegetation at the upper forest borde r–the high-mountain spruce forest with Betula lanata, where Pinus pumila thickets can reach from the overlying belt. The largest amount of allochthonous pollen was found in the pollen spectra on the site without forest canopy. The pollen of broad-leaved trees was brought to high hypsometric levels by mountain-valley winds, rising air currents, from the underlying belts. The quantitative content of pollen of the main dominants of each altitudinal plant zone does not always accurately reflect the role of these taxa in the composition of the communities. The pollen productivity of Betula lanata exceeds the pollen productivity of the main forest forming species in all altitudinal zones, with the exception of the stone birch forests, therefore the share of its participation in the composition of the pollen spectra is overestimated. In the studied pollen spectra the content of Larix pollen is greatly underestimated compared to the role of this species in the forest stand, especially in soil samples from larch forest. It is associated with low pollen productivity, distribution and fossilization characteristics.
The article analyzes the modern ethnic landscape of the Moscow agglomeration on the basis of data from mobile operators. The estimation of the number of foreign migrants and its monthly dynamics from October 2021 to October 2022 is made. The main areas of residence of foreigners have been identified, the ethnic diversity of municipalities has been assessed, and the main types of settlement pattern of national-ethnic communities have been identified. The study showed that the total number of foreign migrants in the agglomeration reaches 1.8 million people or 9% of the total population, remaining almost unchanged in spite of events of 2022, including the special military operation. The share of foreigners is minimal in ZATO (below 3%), it is also insignificant in the far suburbs of Moscow and in expensive districts of the capital city. At the same time, the threshold of 17% (the so-called “boiling point”, reflecting a sharp increase in the risks of interethnic conflicts and ghettoization of urban space) was overcome by 8 municipalities in the agglomeration. The two most noticeable areas of increased concentration of foreign migrants are identified in the south-east at the junction of Moscow and Moscow region (Lublino – Kotelniki) and in New Moscow (Mosrentgen – Sosenskoye). The calculation of the Ekkel ethnic mosaic index confirmed the presence of pronounced interethnic contact zones here. Increased index values were also noted in most central and southwest districts of Moscow, which, with a smaller proportion of foreigners living, are associated with a high density of offices, diplomatic institutions and universities. Three types of settlement patterns of national-ethnic groups of migrants, determined by the adaptive capabilities of ethnic communities, were revealed. Diffuse and relatively uniform settlement pattern is characteristic for both the most massive ethnic groups (citizens of Tajikistan, Uzbekistan and Kyrgyzstan) and the most culturally close to the local population (citizens of Ukraine and Belarus). Concentric settlement pattern (in residential areas of Moscow and satellite cities) is typical for relatively large ethnic groups coming from post-Soviet countries (citizens of Azerbaijan, Armenia, Georgia). The local settlement pattern is typical for small ethnic communities that gravitate to specific districts of the capital city.
The article is devoted to the problem of the formation of geo-cultural texts within the framework of literary geography. An important part of literary and geographical studies is the study of geographical images presented in literary works. The concept of a geo-cultural text makes it possible to typologize literary and geographical images in relation to different geo-cultures. Local geo-cultures with a developed literary tradition usually have a number of representative geo-cultural texts that characterize the landscape and figurative features of the development of a given territory. The evolution of the Black Sea text is considered using the concepts of geo-culture and geo-cultural text. Images of the South, exoticism, and antiquity are explored as key images determining the development of the Black Sea text. Special attention is paid to the formation of interrelations between the images of the Crimea and antiquity. The marine “exoticism,” combined with the “atmosphere” of antiquity, the marginal antiquity of European culture, turned out to be the strongest emotional stimulus for the formation of both southern and Black Sea images in Russian literature. In the geo-cultural context, the “crystallization” of the Black Sea text of Russian literature takes place by the end of the 19th–beginning of the 20th century (I. Bunin, A. Kuprin). This is due to the rich landscape descriptions, which make it possible to talk about the “Black Sea aura” of these texts and the emergence of a kind of “Black Sea ontologies.” Further, the substantial core of the geo-cultural Black Sea text in the 20th century is determined by the works of M. Voloshin, O. Mandelstam, I. Babel, A. Green, K. Paustovsky, V. Kataev. Through the “crystallization” of the Crimean and Black Sea texts and the modern re-creation of its own image of “Black Sea antiquity” throughout the 20th century, Russian culture created its geo-cultural “antiquity” within the framework of the European geo-cultural space. Thanks to the work of I. Brodsky (“Roman” and “imperial” loci), the Crimean and Black Sea texts expand their semantic field, turning out to be a “node” of metaphorical assimilation, uniting the Mediterranean geo-cultural area and geo-cultural zones of influence of Russian literature.
The loess-soil series of Central Asia cover the history of subaerial sedimentation of the last 2–2.5 mln years. Significant thicknesses, a large number of paleosols, and an impressive chronology place the loess-soil series of the Afghan-Tajik depression on a par with the famous sections of the Loess Plateau of China. The study of the most significant sections located within the Khovaling Loess Plateau makes it possible to develop a regional chronostratigraphic chart, to study the structure and conditions of formation of the main stratigraphic benchmarks–buried paleosols. The present study is devoted to the clarification of the structural features of loess and paleosols of the Late Pleistocene in one of the sections of the Khovaling–Obi-Mazar Plateau. Based on the results of stratigraphic dissection, description of the macro- and micromorphological structure, magnetic susceptibility analysis, study of the chemical and granulometric composition, a comprehensive description of the structure and properties was carried out and the most probable conditions for the formation of paleosols and loess were established. In the Late Pleistocene part of the section, two loess layers and a pedocomplex PC1 with three welded paleosols, consisting of a total of 7 horizons, are distinguished. The deposits are characterized by high silt content, carbon content, and the presence of signs of pedogenesis and biological activity in all layers of the studied section. Available data indicate the presence of a poorly developed MIS 3 paleosol in the upper loess layer. The developed pedocomplex PC1 of Obi-Mazar, according to its stratigraphic position, structural features, and magnetic susceptibility data, belongs to the MIS 5. According to preliminary data, its formation occurred in semi-humid and humid conditions under forest vegetation, which contributed to the biogenic segregation of Fe-Mn compounds, as well as intra- and interhorizon redistribution of carbonates due to diagenetic processes. Towards the end of the Last Interglacial, gradual aridization occurred, due to which the upper paleosol to be the least developed.
The geography of research and innovation activity is a traditional topic of research in human geography. Classical studies of the clustering and diffusion of innovation in the 1960s and 70s received a new impetus in the 21st century with the understanding of the openness of innovation and the importance of interregional collaborative networks. Digitalization has played an important role, providing access to new sources of large geocoded data on the movement of key elements of the knowledge economy, including publications as a formalized outcome of scientific activity. The purpose of the article is to identify the center-periphery research ties of one of the largest macroregions of Russia – the Big South of Russia. The aim was to assess the territorial patterns of interregional research networks with the identification of gravity poles and interconnections at the local and national levels. The study uses the method of spatial scientometrics. Geocoded data on publications from the Scopus bibliographic database were used. In the course of the study the hypotheses of “Moscow-centricity” and “St. Petersburg-centricity” of the knowledge domain of the macroregion are tested, the influence of the factor of geographical proximity and the role of the diversity of interregional ties are evaluated, and the “heights-lowlands” of the landscape are revealed. The results of the research have shown a high degree of connectivity between the regions of the Big South of Russia in the research area. The hypothesis about the presence of several centers of gravity of scientific activity in the macroregion was confirmed. First of all, the peaks of the “scientific ridge” of the Big South form Rostov oblast with the largest urban agglomeration in the south of the country, the Rostov urban agglomeration, as well as the Krasnodar krai and Volgograd oblast. The hypothesis of the existence of several centers of scientific activity in the macroregion was confirmed. The influence of the factor of territorial proximity in the formation of research ties is not high and is manifested mainly in the southern Russian regions with relatively low indicators of research output (primarily, it is typical for national republics). Interregional research cooperation between advanced regions is not limited to immediate geographical proximity but is due to a combination of non-territorial factors. The “Moscow-centricity” of the scientific agenda of the regions of the Big South of Russia is true for most of the southern regions of the Russian Federation, which is particularly pronounced in regions with low internal scientific potential and in new regions undergoing a period of transformation of their scientific systems.
The possibilities of using one of the varieties of Big Data – geolocalized photographs – as an objective indicator of the spatial distribution and intensity of tourist and recreational load within the macroregion “From Moscow to St. Petersburg” allocated within the framework of the State Program for Tourism Development are considered. The study uses an original geoinformation model assembled on the basis of freely distributed OpenStreetMap layers and photo points localized in space and time. It allows, on the one hand, to characterize the features of the placement of attractors (natural, cultural) and tourist and recreational infrastructure, on the other – to objectively assess the spatial distribution of the presence of tourists and recreants within the macroregion and describe the specifics of their intra-annual (seasonal) “attraction”. Aggregation of photography points into polygons, taking into account the differentiated clustering distance, made it possible to form areas of seasonal (summer, winter and spring-autumn) stay of tourists, as well as to get an idea of the minimum year-round and maximum episodic areas within the macroregion and individual areas exposed to the potential impact of tourists and recreants. The differences between the minimum and maximum areas of stay of tourists and recreants are proposed to be used to assess the effectiveness of the functioning of the industry in the areas of the macroregion. The obtained spatial areas and patterns of tourists’ presence open up opportunities for an objective assessment of the potential load on natural and cultural heritage sites. The uneven inclusion of both natural and cultural attractors in the sphere of tourism and recreation has been revealed, which leads to a situation where some objects of natural and cultural heritage experience significant industry pressure, while others remain almost or completely unaffected by the presence of tourists and recreants.
The article proposes a methodological approach to the quantitative assessment of direct economic damage from natural hazards for an element of the critical infrastructure of the Russian Federation – railways. The methodology is based on a normative approach to assessing the replacement cost of railway lines, which varies depending on the cost of construction in specific orographic and climatic conditions of a given region. The results are presented in the context of municipalities, which makes it easier to take into account intra-regional differences and to compare them with natural hazard parameters (e.g. floods, dangerous slopes, geocryological processes, etc.). The calculations showed that the marginal cost of replacing railway lines in the event of natural hazards for Russia is about RUB 11 trillion in 2021 prices, or about 8.4% of Russia’s GDP for that year. In a regional context, the first 10 regions account for more than 40% of the total replacement cost, which indicates that these regions require special attention in terms of measures to protect railway assets. These include Irkutsk oblast (RUB 602.4 bln), Khabarovsk krai (595.5), Amur oblast (594.4), Zabaykalsky krai (538.2), Sverdlovsk oblast (526.8), Krasnoyarsk krai (406.8), Altai krai (404.3), Krasnodar krai (348.5), Republic of Buryatia (314.1), Primorsky krai (287.7). The data obtained can be used in studies of natural and man-made risks: by comparing them with the parameters characterising the impact of natural hazards, it is possible to predict the risk and probable damage to railway infrastructure facilities in the given territories. Avalanches and permafrost degradation are used to demonstrate the potential of such assessments.
