NATURAL PROCESSES AND DYNAMICS OF GEOSYSTEMS
Aim. The purpose of this work is to study the dynamics of air temperature and soil temperature in different soil zones of Western Siberia in relation to modern climate change.
Methodology. Based on long-term data from 259 weather stations located on the territory of Western Siberia, an analysis of air and soil temperature distribution and their changes within the areas of nine soil zones (subzones) for the period 1951–2020 was carried out using geographic information systems.
Results. It is shown that in the modern period in all soil zones of Western Siberia there is a climate change towards warming, which is characterized by zonality. The most significant increase in air temperature in the last decade is observed in the north of Western Siberia, especially in the arctic tundra, subarctic tundra and northern taiga subzones, and it becomes less noticeable as we move southward to the steppe zone. Modern warming leads to a change in the temperature regime of soils in Western Siberia and, as a result, a shift of soil-climatic zones to the north. Mapping models of the average annual air temperature for each decade of the period 1951–2020 and the climatic norm 1961–1990 were created, as well as mapping models of air temperature change (average annual and by seasons of the year).
Research implications. The revealed changes in the atmospheric and soil climate must be taken into account when assessing climate risks and developing agrotechnical measures for growing crops, as well as measures to protect infrastructure facilities in the cryolithozone.
Aim. To evaluate the dynamics and load level of dissolved organic matter (DOM) runoff in the river-mouth sections of large Siberian rivers.
Methodology. To calculate the values of chemical runoff, long-term hydrological and hydrochemical information for the period from 1990 to 2020 were used. The dynamics of the organic matter (OM) runoff (including oil products) is considered. A comparative assessment of the runoff of DOM was carried out according to the specific characteristic – the module of chemical runoff – for the mouth sections of such rivers as the Ob, the Pur, the Taz, the Nadym, the Yenisei, the Anabar, the Lena, the Yana, the Indigirka and the Kolyma.
Results. It is shown that the largest values of DOM runoff are typical for the most full-flowing rivers (the Ob, the Yenisei, and the Lena rivers), while the smallest volumes are typical for rivers with a low water runoff. According to such a specific characteristic as the modulus of chemical runoff, the highest runoff values of easily oxidizable OM are recorded for the Pur, the Taz, the Anabar, and the Kolyma rivers, and the highest values of the runoff of hardly oxidizable OM and oil products are recorded for the rivers of the Kara Sea basin. Correlation analysis revealed a statistically significant increase in the runoff of hard-to-oxidize OM in the mouth areas of such rivers as the Ob, the Pur, the Yenisei, the Anabar, the Yana, and the Indigirka. A declining trend of the oil products runoff was identified in the sections of the Ob, the Nadym, the Taz, the Lena and the Kolyma rivers. It has been established that the lower reaches of the Eastern Siberia rivers incur the least total load of the OM runoff and the river-mouth sections of the Kara Sea basin incur the average and high load.
Research implications. Results and obtained data could be used to assess the variability of anthropogenic load and water quality in the mouths sections of the rivers. Also, the findings can be used to study the possible impact of river runoff on the hydrochemical regime of Arctic rivers-mouth ecosystems and coastal marine areas.
Aim. A comprehensive review of literature and scientific data and assessments of the contribution of coastal ecosystems to climate change mitigation processes.
Methodology. A systematic review of information sources was conducted. Information was searched in various databases: Science Direct, Wiley, Taylor & Francis and others. The method of searching articles by keywords was used. The search for articles covered the period from 2002 to 2022 and was limited to publications in English.
Results. The number of scientific publications assessing the role of coastal wetlands in climate change mitigation increased significantly 2013–2022. The publications focus on regulating and supporting ecosystem services. The promising direction of regulating blue carbon stocks, whose reserves are concentrated in mangrove forests, is highlighted.
Research implications. The findings can be used for further systematic reviews, to improve economic and political management of wetlands.
NATURAL AND ANTHROPOGENIC PROCESSES AND NATURE PROTECTION
Aim. Investigation of the possibility of using modeling of the processes of the impact of the “landfill MSW – environment” system on the air environment to assess and develop solutions to minimize such impacts.
Methodology. The research uses: a systematic approach to modeling the processes of interaction of waste disposal facilities with the environment, calculation and modeling of gas emission processes based on: the values of the specific yield of biogas during the period of its active stabilized generation during methane fermentation and the period of complete fermentation of the organic part of the waste, taking into account the temperature conditions of the area of the object location; annual data on the amount of accumulated waste at the facilities; values of wind speed and direction, the degree of vertical stability of the atmosphere according to the average long-term data of observations of weather stations closest to the objects.
Results. The method of informational, including retrospective, modeling makes it possible to analyze the volumes and dynamics of gas-emission processes of different-age municipal solid waste disposal facilities, to assess and predict their environmental impact.
Research implications. The method of modeling gas emission processes in the MSW landfill – environment system is recommended to optimize eco-safe control of the system at all stages of its life cycle, as well as in case of waste burning.
Aim. An attempt is made to form a concept for the prevention and timely protection of the Lake Kenon (western part of the city of Chita, Trans-Baikal Territory) ecosystem from external and internal threats.
Methodology. Research in the field of afforestation and reforestation has been worked out. Functional zones have been identified, depending on the role played in the ecosystem, the composition of incoming pollutants, allowing one to prevent the development of erosion processes.
Results. A set of measures to preserve the ecosystem of the lake has been developed, taking into account the landscape differentiation of the territory.
Research implications. Functional zones are identified that serve as the basis for carrying out activities to enhance the ability to self-clean, or reduce the negative impact on the ecosystem. The developed complex of measures for the improvement of territories with a full-fledged infrastructure will allow one to combine opportunities for active recreation and to stimulate the development of the economy and increase the investment attractiveness of the city.
POPULATION GEOGRAPHY AND SOCIAL ECOLOGY
Aim. To identify the main trends in the population dynamics of urban settlements of the Russian-Belarusian border area in the 21st century to optimize regional policy based on the most sustainable urban centers.
Methodology. Based on the data of current accounting and censuses, the dynamics of the population of cities and urban-type settlements of the border regions of the Republic of Belarus and the Russian Federation, depending on their population, administrative status and geographical location, is considered. The methods of spatial analysis were used in the work, the grouping of small urban settlements by population and the typology by functional and hierarchical significance were given.
Results. It has been revealed that large urban settlements (with a population of more than 100 thousand people), regional centers, districts centers and centers of intra-regional border regions, which usually differ in significant sizes (mainly large and medium-sized cities), have an administrative status and an advantageous geographical location, are developing most steadily.
Research implications. The results obtained indicate that the processes of regionalization are actively underway in the Russian-Belarusian border area. Historically formed intra-regional regions are developing as life support systems for their largest urban centers – regionopolises. Intra-regional regions can be used as a basis for optimizing regional policy in the border area of Russia and Belarus. On the basis of the accelerated development of regionopolises, it is possible to activate the development of the entire system of urban settlements of the Russian-Belarusian border area.
Aim. Reconstruction and analysis of the evolution of socio-ecological factors of the formation of green spaces of the Siberian city on the example of Tyumen.
Methodology. The historical ecology of the city has been studied by actor’s approach. It means that some intellectual ideas, urban planning standards, institutional and informal communities of people may be considered as actors that shaped the green spaces of the city. At the same time, in the process of their development, certain elements of green spaces begin to play the role of natural actors that affect social behaviour and quality of people’s life.
Results. A reconstruction of the socio-ecological aspects of the main stages of green spaces formation in Tyumen in the period from the 19th to the beginning of the 21th century was undertaken. The influence of social actors on the principles of the formation and reproduction of green spaces has been identified and analyzed.
Research implications. The study formulated heuristic capabilities of the actor approach in the studies of socio-ecological interactions in green urban spaces. Retrospective study of the evolution of the development of urban socio-natural complexes from the standpoint of historical ecology makes deeper understanding the utilitarian and cultural significance of different elements of green spaces, as well as take into account the positive and negative experience of their creation in the modern practice of green infrastructure development in the city.
ECONOMIC GEOGRAPHY AND SPATIAL DEVELOPMENT CHALLENGES
Aim. Identify the essence and typical forms of industrial park as a modern form of production organization, examine the prerequisites, experience and prospects of creating industrial parks in the Kemerovo region − Kuzbass.
Methodology. Theoretical methods, including analysis and generalization of materials of regulatory and methodological documents, scientific publications, as well as information from official websites of companies on the subject of research are used. The location of industrial parks in the Kemerovo region – Kuzbass is clearly reflected by using the cartographic method.
Results. The analysis of regulatory documents and scientific publications allowed us to formulate industrial park features as well as the types and advantages of industrial parks creation. The study found that there is a necessary infrastructure to create parks of different types in the Kemerovo region – Kuzbass. These measures will allow to diversify the economy and solve the problem of mono-dependence, which is urgent for the region.
Research implications. The study allows us to analyze and summarize the features, types and advantages of creating industrial parks as a modern form of production organization, which is especially relevant for the typical industrial region, which includes the Kemerovo region − Kuzbass.
Aim. To form a holistic picture of the European Union’s regional policy on rural development, its relevance and effectiveness, for, potentially, the further use of the European experience.
Methodology. The reservoir of sources on the development of rural areas in the EU was analyzed. An analysis of the views of European researchers on the problems of rural development was carried out. The main content of the study is an analysis of the methods, concepts, programs for the development of rural areas of the European Union.
Results. The study concluded that the success of European rural development depends on a number of factors: taking into account the regional characteristics of a particular area, one or another individual agriculture; extensive experience of development in the conditions of capitalism and healthy competition; endogenous-territorial approach. Previously poorly studied material on the topic under study is summarized.
Aim. The purpose of the paper is to study the issues of social infrastructure areas and territorial planning, the implementation level of adopted State programs, and the current state of water, sewerage, electricity, heating, transport, road, and service spheres of the communal areas of the population.
Methodology. The key research method is the methodology for determining of the territorial development index coefficient, comparative analysis with other regions and historical analyses, and mapping all infrastructures in the region.
Results. Research shows that although the State programs and measures are implemented in the Shaki region, the development of social infrastructure is not at the desired level. However, the social infrastructure and its separate areas of water supply, gas supply, and sewage systems in the researched area and villages are not comprehensively provided.
The regional development index reveals that Shaki district ranks 4th in Shaki Zagatala economic region. According to the conducted research, the volume of the measures taken in the direction of the development of the region is mostly concentrated in Gabala, Zagatala, and Gakh regions in recent times. As a result, it was determined that the Shaki region’s function of preventing migration in the region, as well as its role as an economic center, has decreased, and the region has transitioned from monocentric to polycentricity.
Research implications. The results of the study show that mapping the sites of social places and infrastructure using GIS technologies is important in developing social strategy plans and databases as a significant factor in the socio-economic development of the Shaki region.
INVITATION TO DISCUSSION: NATURAL RESOURCE ISSUES
Aim. Analysis of the objectivity and competence of assessments by foreign researchers of reserves and resources of minerals in the liberated territories of the Russian Federation, expressed, including in monetary terms.
Methodology. Publications in Western media, discussion of these publications on Russian information portals, Russian and foreign encyclopedic online publications, as well as archival materials from the period of restoration of Donbass were analyzed.
Results. The given list of deposits of mineral raw materials does not correspond to the real figures reflected both in the state balance of mineral resources of Ukraine and earlier information on the Ukrainian SSR as part of the USSR. Open foreign sources on coal in the Northern Black Sea region do not take into account the work necessary to restore the level of extraction of mineral raw materials and its primary processing to the level of 2014. Publications show the lack of professional competence of peer-reviewed articles, including those in the Encyclopædia Britannica.
Research implications. This analytical study shows the level of incompetence and bias of foreign researchers in assessing mineral reserves and resources, while simultaneously revealing real factual data on subsoil use and monetary assessment of the volume of mineral resources in the liberated territories of the Northern Black Sea region.
BIOINDICATION OF ENVIRONMENTAL CONDITIONS
Aim. To assess the applicability of soils for growing medicinal plants.
Methodology. In order to identify the applicability of potting soil in the cultivation of medicinal plants, the germination of planting material, vegetation, and biochemical parameters of the grown plants were studied. Commercial soils Grunt ECO, Veltorf peat mixture, Substrates Select seed germination soil were studied as substrates, native soil of field crop rotation was taken as a control, and cress was used as an indicator plant species. The main studies were carried out on different medicinal plant cultures.
Results. The possibility of using the studied soils Grunt ECO and Substrates Select for growing medicinal plants, as well as cress, is shown. When evaluating the phytoapplicability of the Veltorf peat soil, the death of some of the studied plants was noted.
Research implications. The studied soils are products of industrial biotechnological processing of wastes, which determines the expediency of expanding the areas of their use. In the present study, the possibility of using soil-soil compared to native soil of field crop rotation for cultivation of medicinal plants was determined. Their composition and properties significantly depend on the initial components and fermentation technology, and their applicability for different purposes should be studied.
