Goal of the research. In 2014 in Ukraine the massive decentralization reform has been initiated. It aimed to transform many single administrative units into much larger territorial communities. Spatial differentiation of the newly consolidated communities by values of their proximity to large cities and urban areas within the case of Zhytomyr region is the goal of the article. Methods of the research. Zhytomyr region is one of the most successful in Ukraine on implementation of the administrative reform, decentralization and best practices of the communities’ integration. The region had been selected for the in-depth study taking into account its central location, economic situation and the environment. Data of the State statistics agency of Ukraine, governmental and non-governmental institutions and Google Maps was applied to conduct the research and identify the territories’ groups. The research results. Aiming to perform spatial typology of the newly consolidated territorial communities we differentiated them depending on their proximity to cities and other urban centers firstly. Consequently three types of the communities have been defined: neighboring, relatively remote, and faraway. Distance of the communities to urban centers relates with their area and people size: the closer a territorial unit is located to the city, the smaller is its area and population. Other words, the proximity of a community to the city determines its economic capacity much more than its population and area. Statistical relations between duration of the communities’ consolidation and their spatial types prove the faraway and relatively remote communities have been united earlier than the neighboring. Taking into account the average number of settlements belonging to the one consolidated community it is revealed the closer to the regional center communities include less number of settlements. Two-dimensional classification of the communities by their proximity to regional and rayon centers confirms communities located close to cities and towns have better opportunities for the development. Novelty of the research results. The presented methodological approach to comprehensive differentiation of the territorial communities can be applied to identify their challenges, threats and prospects. For this purpose, the algorithm is proposed which combines indicators of spatial differentiation of rural areas, their economic status, social infrastructure, and the environment. Practical significance. The proposed methodological approach to spatial differentiation of rural territories is aimed assisting representatives of the communities, local self-government bodies and state authorities to develop and refine local strategies and programs, update coherent plans and identify target communities for certain projects.

Formulation of the problem. One of the main manifestations of regional climate changes in Ukraine on the background of global warming is substantial rise of air temperature and increasing of extreme weather conditions. Therefore heat waves became a concern. Detection of heat waves and their physical and statistical characteristics on the territory of Ukraine was done by many researchers only during warm period of the year and on the basis of fact data. But it's interesting to find out what happens in this context during cold period as well because heat waves affect not only human health but also agriculture, transportation etc throughout the year. Besides in order to overcome negative consequences and for adaptation of people for climate changes prognostic values of meteorological indices, in particular air temperature according to modern climate change scenarios. Review of previous publications. Consequences of thermal waves impact on population health is being studied in different countries of the world and in the main medical data base PubMed there are more than 1000 publications in this branch of research. But still there is no universal definition of heat waves which could be used as criteria for detecting this anomaly in all the researches. This can be explained that depending on challenges of scientific research or practical service of household activity waves of certain intensity or duration can be the most interesting. Purpose. The aim of this work is detection of heat waves on the basis of actual and scenario data and analysis of their physical and statistical characteristics and dynamics until 2050. Methods. Heat waves were detected on the base of actual data and model ranges by low (RCP 2.6), medium (RCP 4.5), high (RCP 8.5) levels of greenhouse gases emissions and also there were analyzed their physical and statistical characteristics and dynamics until 2050 in different regions of Ukraine. Results. The smallest annual number of heat waves is recorded in the south of Ukraine and the maximum heat wave duration is approximately the same at all the research stations (Uzhgorod, Kharkiv, Odessa). According to all climate change trends that were used, the greatest number of heat waves in the next thirty years is expected in the south of Ukraine, with a maximum in the cold season (October-April). The intensity of heat waves, expressed by the cumulative temperature, during the cold period slightly exceeds this index during the warm period in the west and north-east and substantially exceeds it in the south, and heat waves of the same duration can have quite different intensities. Conclusions. In the west of Ukraine, there is a trend of increasing the number of heat waves and their duration over the studied period by decades, in the northeast and south - these indicators have fluctuated. It was discovered that in all regions, according to actual data, heat waves of 6-9 days have the highest recurrence (82% of total amount of heat waves

Formulation of the problem. Solving the problems of urban transport communications, in particular the constantly growing intensity of automobile traffic in megalopolises, is one of the main directions of minimizing the environmental and man-made risks of the urban environment. Global concepts of greening large cities pay considerable attention to the possibilities of underground space to take on the functions of the most dangerous and risky surface objects and communications, since the impact of any underground object on the environment is much lower (than similar on the surface) and can be better controlled. At the same time, planning for the development of underground transport infrastructure should be based on a systematic methodology and tools for analyzing complex systems. Purpose. It consists in the use of system tools (BOCR method - criteria of benefits, opportunities, costs and risks) for planning underground transport infrastructure of large cities to ensure minimization of environmental and man-made risks of urban space and prioritization for the construction of road tunnels (for example, the General Plan of the Kiev city). Methodology. A methodology and decision support toolkit for calculating the priorities of alternatives based on hierarchical and network criteria models are proposed. The modified BOCR method developed by the authors (N. Pankratova, N.I. Nedashkovskaya) was applied to assess decision alternatives taking into account benefits, costs, opportunities and risks. Results. System models of two road tunnels, according to the General plan of the Kiev city until 2025 were developed. Assessment of the models using the BOCR method (criteria for benefits, opportunities, costs and risks) was performed. The priorities of alternatives for tunnels' routes aggregated over a network of parameters and a reasonably expedient sequence of their construction were calculated according to the criteria for reducing the environmental and man-made risks of the urbanized space. Scientific novelty. For the first time, the target function of the system model for the development of underground infrastructure in large cities is to minimize the environmental and man-made risks of urban space. The capabilities of the modified BOCR method have been expanded and two alternative tunnel track models have been successfully tested. Practical significance. The research methods and results provide investors, city state administrations and public organizations with an effective toolkit for assessing the priority of the construction of underground urban facilities to regulate urban development in order to improve environmental standards and the safety of life in megacities.

Purpose. This study aims to analyze the regional differentiation of youth migration flows and typify the regions of Ukraine according to the characteristics of the migratory behavior of the youth. Accordingly, the research questions are as follows: 1) what is the relationship between economic indicators (income, unemployment, investment) and youth migration at the regional level? 2) how do the regions of Ukraine differ in the scale, structure, and dynamics of youth migration flows? 3) what types of regions can be identified, and can they be considered to determine the young people’s intention to migrate? Research methods. Pearson's correlation coefficients were calculated to assess the relationship between youth migration and economic indicators at the regional level. To prevent skewed indicators distribution, the city of Kyiv was excluded from the analysis. In order to study the regional differentiation of youth migration, we used cluster analysis and constructed Kohonens self-organizing maps. Based on the analysis of spatial and temporal (from 2002 to 2019) trends, we also developed an empirical typification of the regions according to the migration behavior of young people. Main findings. The analysis of spatial differences in youth migration in urban and rural areas shows the diversity and complicated multidirectionality of migration flows. Youth migration has been found to be linked to unemployment and investment attractiveness at the regional level. The assumption that the migration of young people from rural areas is influenced not only by economic factors but also by the lack of prospects for tertiary education, jobs, and the ‘culture of migration’ has been confirmed. The analysis of the relationship between income and out-migration scale shows some signs of a inverse U-shape curve. In general, the results of the study confirmed that at the regional level, economic indicators (unemployment, investment, and income) affect youth migration in Ukraine, but their impact needs to be studied in the broader context of place-specific human capital and life-course transition. Based on the results of cluster analysis and construction of Kohonen self-organizing maps, five clusters of Ukraine’s regions by the similarity of youth migration were identified. The analysis of youth migrations in 2002-2019 allowed to identify six models of their dynamics (monotonically decreasing, abrupt dynamics with a tendency to decrease, abrupt dynamics without changes, abrupt dynamics with a tendency to increase, monotonically increasing, without changes). According to the combination of selected clusters of regions and models of youth migration dynamics, we empirically typified Ukraine’s regions into three groups that can be considered those that, to some extent, determine the young people’s intention to migrate. However, further research should be aimed at analyzing the individualization of migration behavior and liquid migration of Ukrainian youth. Scientific nov

Formulation of the problem. The article is devoted to the description of the implementation of special engineering-geological researches in the territories of industrial and urban agglomerations. The purpose of the article is to show the possibilities of special geophysical researches while studying hazardous geological processes and the determination of the physical and mechanical properties of soils under the foundations of buildings in conditions of dense urban development. Materials and methods. To achieve the main goal, special equipment was used in the work – a horizontal sounding and logging unit. It is intended for mass and most reliable research of soil properties at the base of existing buildings and structures. Using this installation, the following tasks are solved: drilling horizontal wells; selection of soil monoliths; static sounding using «Pika» equipment; radioactive logging; pressiometric researches of soils; immersion of injectors to consolidate the soil. Results. Analysis of the performed engineering and geological surveys at the site of the emergency workshop № 22 of PA «Krasitel» in the city of Rubezhnoye, Lugansk region and at the site of reconstruction of the hostel on the street Studencheskaya, 4 in Kharkov showed the possibility of using special geophysical research in the conditions of industrial and urban agglomerations. To find out the cause of the emergency deformation of the structure of the emergency workshop № 22 of PA «Krasitel», a study of soils was carried out using the method of radioactive logging. Obtained results are presented in the form of a diagram of the isodensity of the base soils. Zone of decompaction of the base soils has been identified and delineated. Based on the materials obtained, it was concluded that the main reason for the collapse of a part of the building is the additional subsidence of the foundations as a result of mechanical removal of soils into the destroyed sewer collector located below the base of the foundations. On the site of reconstruction of the hostel on the street Studencheskaya, 4 in Kharkov, the density of soils under the foundations of the existing building was determined by the method of gamma-gamma logging. It was found that under the foundations in the zone of stress development, an increase in the density of the foundation soils is recorded. Outside the stressed zone (between foundations), the density of soils is significantly reduced and corresponds to the background values. Scientific novelty and practical significance. Scientific novelty – the choice of a complex of special geophysical studies in researches of hazardous geological processes and to determine the physical and mechanical properties of soils under the foundations of buildings in conditions of dense urban development of industrial and urban agglomerations is scientifically substantiated.

Formulation of the problem. Ukraine's energy sector is import-dependent, and one of the country’s sustainable development goals until 2030 is to ensure access to affordable, reliable, sustainable and modern energy sources. The wind potential of the mainland of our country has been thoroughly studied, so the focus of our interest is water areas, which are promising for the development of offshore wind energy. Offshore wind farms in Ukraine could improve the environmental situation and considerably contribute to the decarbonization of domestic energy. That is why the study considers the opportunity of offshore wind farms installation in the Sea of Azov. Methods. The analysis of literary and cartographic sources has been carried out. Mathematical methods have been used to calculate energy indicators. Using geoinformation modeling, taking into account limiting factors, suitable for the installation of offshore wind farms areas have been identified in the Sea of Azov. The purpose of the article is to geographically analyze the wind energy potential of the Sea of Azov with further assessment of the suitability of areas for the offshore wind farms location. Results. Our research has shown that the installation of offshore wind farms is appropriate in the Sea of Azov, because many areas are characterized by average annual wind speed above 6 meters per second. The most promising areas are the northern and northeastern coasts, where wind speed at different altitudes ranges from 8 to 9.3 meters per second. At altitudes of 50, 100 and 200 m, under the action of limiting factors, the most promising for offshore wind turbines areas are reduced by 8–22%. As considered limiting factors (territorial waters, nature protection objects, settlements and airports) have identical influence regardless of height, it is more effective to install wind turbines with a tower height of more than 100 m in the waters of the Sea of Azov. Interdisciplinary research is needed for the final answer on the effectiveness of offshore wind turbines in the Sea of Azov. Scientific novelty and practical significance. The results of the analysis of the wind energy potential of the Sea of Azov have been given, the tendency of its growth from the west to the east has been revealed. Attention has been paid to the method of geoinformation modeling of the location of offshore wind farms taking into account limiting factors. Maps of wind speed, potential of electricity generated by a single wind turbine and suitability of areas of the Sea of Azov for the location of offshore wind farms at an altitude of 200 m above sea level have been presented. These data can be used by designers of wind energy facilities as a basis for determining the optimal power of wind turbines and the type of energy for a particular area of the Sea of Azov.

Ukraine's energy sector is import-dependent, and one of the country’s sustainable development goals until 2030 is to ensure access to affordable, reliable, sustainable and modern energy sources. The wind potential of the mainland of our country has been thoroughly studied, so the focus of our interest is water areas, which are promising for the development of offshore wind energy. Offshore wind farms in Ukraine could improve the environmental situation and considerably contribute to the decarbonization of domestic energy. That is why the study considers the opportunity of offshore wind farms installation in the Sea of Azov. Methods. The analysis of literary and cartographic sources has been carried out. Mathematical methods have been used to calculate energy indicators. Using geoinformation modeling, taking into account limiting factors, suitable for the installation of offshore wind farms areas have been identified in the Sea of Azov. The purpose of the article is to geographically analyze the wind energy potential of the Sea of Azov with further assessment of the suitability of areas for the offshore wind farms location. Results. Our research has shown that the installation of offshore wind farms is appropriate in the Sea of Azov, because many areas are characterized by average annual wind speed above 6 meters per second. The most promising areas are the northern and northeastern coasts, where wind speed at different altitudes ranges from 8 to 9.3 meters per second. At altitudes of 50, 100 and 200 m, under the action of limiting factors, the most promising for offshore wind turbines areas are reduced by 8–22%. As considered limiting factors (territorial waters, nature protection objects, settlements and airports) have identical influence regardless of height, it is more effective to install wind turbines with a tower height of more than 100 m in the waters of the Sea of Azov. Interdisciplinary research is needed for the final answer on the effectiveness of offshore wind turbines in the Sea of Azov. Scientific novelty and practical significance. The results of the analysis of the wind energy potential of the Sea of Azov have been given, the tendency of its growth from the west to the east has been revealed. Attention has been paid to the method of geoinformation modeling of the location of offshore wind farms taking into account limiting factors. Maps of wind speed, potential of electricity generated by a single wind turbine and suitability of areas of the Sea of Azov for the location of offshore wind farms at an altitude of 200 m above sea level have been presented.

Formulation of the problem. Global climate change causes transformation in the humidification regime and, as a result, makes adjustments to economic activities and features of water use. In the context of Ukraine, against the background of climate change, the runoff of most domestic rivers is declining, which especially in the limited period exacerbates the issue of balanced use of ecosystem services of aquatic ecosystems and prioritization of needs during resource allocation, control of rivers and establishment of their functioning. The purpose of the article. Recognizing the strategic importance of freshwater ecosystems in ensuring sustainable regional and national development, the study of the Southern Bug River was aimed at assessing its ecological status in order to identify sources of negative anthropogenic impact and identify general ecosystem distortions that may affect the functional integrity of the aquatic ecosystem. Methods. The research points on the Southern Bug River were determined by the method of randomization. The total length of the route was about 200 km. Also, the spatial location of settlements was taken into account, so that the investigated points were both upstream and downstream. Measurement of physicochemical parameters was performed by instruments: TDS-3, TDS/ЕС/Temp-meter HM COM-100, pH-meter Ezodo 6011A. The task of hydrobiological research was to find and identify species at the family level. The research was conducted at the end of July 2020, when the river entered to low flow phase. Results. On the basis of field research, the assessment of the ecological state of the Southern Bug River in the lower course (from the city of Pivdennoukrainsk) was carried out in the work. Regularities of pH dynamics and mineralization of the aquatic environment are established. The limits of the spatial influence of the Black Sea waters on the Southern Bug, the continental advance of which (upstream) almost 100 km up is due to the high level of regulation of basin runoff, have been specified. The same processes, as a consequence, affect not only biodiversity, but also the features of industrial and domestic water use. Using the stenobiontic approach, the level of ecological safety of the Southern Bug ecosystem in the lower course was assessed. Based on the obtained results of stenobioindication, the zoning of the studied area of the Southern Bug is proposed, which compares quite well with the results of pH and mineralization measurements. Only 1% of the route, which corresponds to the porous section of the river channel, was classified as a "healthy ecosystem". The closer to the mouth, the pH of the water gradually increases, which contributes to the intensification of the eutrophication process. Scientific novelty and practical significance. The obtained results are considered to be an integral part of future field research on the identification of sources of negative impact on the aquatic ecosystem of the Southern Bug. The n

Formulation of the problem. This article is devoted to the critical topic of modern Urban studies –the river’s role in urban space. There are many projects of the river’s revitalization in the USA, South Korea, and Europe. These projects improve the condition of climate and ecology in cities and renew rivers have become attractive places for citizens and tourists. In Ukraine, such projects are not so popular, but during the last years, in several cities NGOs, which try to attract attention to this topic, have appeared. Nevertheless, the revitalization project must begin from the deep investigation into the history and natural condition of the river. Therefore, this article’s object is the interaction between the Rivers and the Society in the Kharkiv urban space during the second half of 17th – the early 21st century. The topic was divided to five periods. The first was the second half of 17 – the middle of 18, when the city was the fortress on The Wild Field’s border. Next – 1764 – 1860, when Kharkiv was the typical administrative center of The Russian Empire. Then 1860 – 1917, when the city’s impetuous development dramatically accelerated anthropogenic pressure on the urban space. The fourth – 1917 – 1991 when the town was under Soviet Urban policy. The last – the modern period of Ukrainian Independence, when the revitalization projects have become the actual. Review of previous publications and studies. Kharkiv blue space’s condition was the important theme for historians, ecologists, architects and politics during the 19th – 21st centuries. The global subjects of the river in urban space were started to discuss in Europe in 19th century because of the influence to the river by the industry leading to ecological problems. During the last ten years, L. J. Martin attracted the attention to the history and revitalization of the Providence river (USA). S. Castonguay, M. Evenden published the profound research about the river in urban space. Jaime Lerner determined the place of river in his research «Acupuntura Urbana» Ukrainian ecologists continue to study the level of pollution in Udy, Kharkiv and Lopan. Methods. Using the original Urban Studies methods we considered the rivers as a part of the symmetry urban network. It means that the river is an active actor of the urban connection and can influence the other elements of the net. Results. During the five periods of our theme, river were played the next roles in urban space – sewage, zoning, economic, recreational, and aesthetic. The meaning and scale of these functions were changed according to the historical period. Unregulated use of water sources leads to the pollution of rivers, the spread of infection, and the floods. Scientific novelty and practical significance. The revitalization process starts from the profound cross-disciplinary research about the place of rivers in Kharkiv Urban space.

Formulation of the problem. Hydrocarbon pools in hydrodynamic traps are known within many oil and gas provinces. The Dnieper-Donets basin is one of the regions where non-vault traps of almost all types and associated with them hydrocarbon pools are widespread, while HT in DDD are not yet typical, although the geological structure of the region indicates the possibility of their formation. Thus, substantiation of the role of geological preconditions in the processes of hydrodynamic type traps formation is the main task of the work. Analysis of recent research and publications. In the monograph of O. Plotnikov (2001) among the promising regions for the search for HT defined DDD. The reason for this was the data on the presence in some productive horizons, in particular in the Sorochinsky and Rudenkivsky fields, of formation waters that lie above gas-bearing deposits. It is believed by some researchers, that the leading role in the formation of gas accumulations at these fields belongs to formation waters. According to the results of geological and geophysical study of the southern slope of the Kalmius-Torets depression and the Krasnoarmijska monocline in the south-eastern part of the DDD (A. Terdovidov (2000), S. Pavlov (2004), favorable geological prerequisites for the formation of HT in Paleozoic sediments established. Selection of previously unsolved parts of the overall problem. The general problem of searching for HT in the DDD as a whole task has not been solved so far. Formulation of the purpose of the article. Estimation of possibilities of a new direction of search and reconnaissance works in DDD, namely on non-traditional non-vault traps of hydrodynamic type substantiation. Results. The Visean dominant productive complex, regionally extended on the monocline slopes of the northern and southern sides of the depression and lithologically represented mainly by sandy horizons, was selected for priority research. The significant content of alluvial sandstones in Visean sediments section allowed the authors to consider them as special reservoirs of fluids, and paleoalluvial systems to study in the rank of independent search objects. Their territorial location is logically related to the existing deflections of the surface of the crystalline basement, most of which are associated with modern river systems, which indicates the current functioning of their relationship. The authors made an attempt to substantiate within the northern side of the DDD the following forecast water exchange systems: 1) expultional overflowing; 2) docking regime (both in the terminology of O. Plotnikov) in Paleozoic sediments; 3) infiltration water exchange in Mesozoic sediments, as necessary conditions for catching migrating upward hydrocarbons. The decrease in the infiltration waters velocity to insignificant values is interpreted by the authors as a typical phenomenon for "closed" monoclines, within which there was an equilibrium between the pressure of infiltra
问题的表述。水动力圈闭中的油气藏在许多油气省都是已知的。第聂伯-顿涅茨盆地是几乎所有类型的非拱顶圈闭及其伴生油气藏普遍存在的地区之一,而DDD的高温圈闭尚不典型,尽管该地区的地质构造表明了其形成的可能性。因此,证实地质条件在水动力型圈闭形成过程中的作用是本工作的主要任务。分析最近的研究和出版物。在O. Plotnikov(2001)的专著中,在寻找HT的有希望的区域中定义了DDD。其原因是在一些生产层位,特别是在Sorochinsky和Rudenkivsky油田,位于含气矿床上方的地层水的存在数据。一些研究人员认为,在这些气田的天然气聚集形成中起主导作用的是地层水。A. Terdovidov (2000), S. Pavlov(2004)对DDD东南部Kalmius-Torets凹陷南坡和Krasnoarmijska单斜的地质和地球物理研究结果,为古生代沉积物中高温沉积的形成奠定了良好的地质条件。选择整体问题中以前未解决的部分。在整个DDD任务中搜索HT的一般问题到目前为止还没有得到解决。文章目的的表述。在DDD中搜索和侦察工作新方向的可能性估计,即水动力型物质的非传统非拱顶圈闭。研究重点选择了在凹陷南北两侧单斜斜坡上区域伸展、岩性以砂质层为主要代表的Visean优势生产杂岩。Visean沉积物剖面中冲积砂岩的显著含量使作者可以将其视为特殊的流体储层,并将古冲积体系作为独立的搜索对象进行研究。它们的领土位置在逻辑上与晶体基底表面的现有偏转有关,其中大多数与现代河流系统有关,这表明它们之间的关系目前正在发挥作用。作者试图证实在干旱区北侧预测的水交换系统:1)排出式溢出;2)古生代沉积物的对接机制(都是O. Plotnikov的术语);3)中生代沉积物的入渗水交换,是捕获向上运移的油气的必要条件。入渗水流速降低到不显著值,作者认为这是“封闭”单线的典型现象,在这一现象中,入渗水压力与排出流体阻力之间达到了平衡。这种平衡被看作是为水动力捕获创造条件的术语。结论强调需要进行全面的研究,以确认水交换的预测模型,并获得绘制可能存在碳氢化合物聚集的最小压力测量值的数据。
