To date, an extensive literary material has been accumulated on this problem, concerning the causes of its occurrence, analysis of the patterns of development, and the possibilities of managing risks, including the environmental ones. It has been established that the list of reasons for the formation of risks in cities lacks one of the most important factors that we have discovered – the structure of urban landscapes, which are quite large objects of urban development. To identify the role of these objects in the formation of environmental risks, the cities of Orsha and Pinsk were selected. These cities were laid down almost simultaneously at the beginning of the 11th century, but they have a different history of development. Maps of urban landscapes of cities were compiled, geochemical studies of their soil cover were carried out, geochemical and thermal anomalies of the surface were revealed, the volumes of ecosystem services (carbon absorption) by green spaces were calculated. It was found that urban landscapes perform various functions in the system of environmental risks: some of them contribute to the development of hazardous processes, others – to mitigate them. So, soil pollution with heavy metals (with an excess of the content of Pb, Cr and Cu over the MPC by 1.2–5.6 times in Pinsk), the strongest heating of the surface (8–16 °C higher than the air temperature in Pinsk and Orsha) and low carbon deposition (100–500 t per year) are typical for urban landscapes of the historical center, urban landscapes with a predominance of industrial buildings, urban landscapes for complex residential multi-storey, public and industrial buildings. Urban landscapes, in the structure of which there are elements of landscape and recreational areas of public use (parks, forest parks, squares), as well as agricultural lands and water bodies, are characterised by a low content of heavy metals in soils (below the MPC in Pinsk, below the background in Orsha), low surface temperature (2–3 °C higher than the air temperature), high volume of carbon deposition (2.6–2.8 thsd t per year). An assessment of the probability of risks associated with the described processes was carried out, which helped to find out that they correspond to the categories of «acceptable» and «neglected», options for risk management were proposed.","PeriodicalId":52778,"journal":{"name":"Zhurnal Belorusskogo gosudarstvennogo universiteta Geografiia geologiia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42653582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The precipitation expected changes were studied for period of 2021–2099. It was established that precipitation growth up to 20–30 % in winter during 1989–2019 in comparison by 1948–1988, is connected with increase the number of days with weak precipitation and caused by growing duration of liquid precipitation falling. In summer the reducing of rain falling duration was noticed over territory of Belarus. At the same time the significant growth of precipitation maximal totals per day by 20–30 % was detected. The largest growth was found in the south of the country. Dry days number raised by 1–4 days and dry and hot days numbers raised by 1–2 days per decade. The repeatability of atmosphere droughts of different gradations increased up to 2–26 % by the majority of meteorological stations. According to climate projections based on the EURO-CORDEX-11, the growth of yearly and seasonal precipitation is expected over territory of Belarus. The precipitation increase is connected with growth of intense precipitation. At the same time, the dry periods duration is projected to rise in the warm part of the year.

The purpose of the study is to characterise modern processes in the global manufacturing industry, to show the changing role of regions in the world industry and world trade in products of knowledge- and technologyintensive (KTI) industries with varying degrees of research and development (R&D) intensity, to identify the role of a new leading region, as well as the positions of China and other countries. In the course of the research, Asia’s stable leadership in the production and export of products of high-technology industries with varying degrees of R&D intensity was established. It is shown that at present the Asia region is the leader, first of all, due to the industrial development of China, the share of which is about 30 % in the production of products of the world manufacturing industry. At the same time, the share of China in the manufacturing industry of the Asian region (the modern leader of the world industry) exceeds 50 % (as well as in the trade in industrial products of the countries of this region) already. China came out on top in the export of all groups of high-technology goods with varying degrees of R&D intensity, including in the export of high-technology goods with high R&D intensive (23 and 20 % of world exports, respectively). China is the leader in the production (26 %) and export (12 %) of high-technology goods with medium-high R&D intensity also. The strengthening of the position of the Asian region in the world industry and world trade of knowledge- and technology-intensive goods in the second decade of the 21st century is revealed.","PeriodicalId":52778,"journal":{"name":"Zhurnal Belorusskogo gosudarstvennogo universiteta Geografiia geologiia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45783125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is due to the objective need to develop mechanisms of overcoming the demographic and economic peripherality of the region and embedding regional economic systems of border regions into the system of local relations. The purpose of the research is to identify the current distinctive features of the demographic and economic development of the inter-capital space of the Belarusian-Russian border region with the establishment of its niche from the point of the central-peripheral approach. During the analysis of the demographic situation of the inter-capital space of the Belarusian-Russian borderlands, it was established that, generally, in 1999–2019, its main feature was peripherality with the three zones established – the central demographic periphery, the buffer demographic periphery and the demographic semi-periphery – with a predominance in the structure of the first zone. Geographically, the central periphery zone is formed mainly by the rural borderland areas. According to the results of the analysis of the industrial development level, it was discovered that the inter-capital space of the Belarusian-Russian borderlands is characterised by a high degree of spatial inequality due to the development of large industrial centers around the existing periphery. This research had established a spatial differentiation of the transportation accessibility (by the connectivity of administrative centers of the borderlands) and the productivity of road transportation. The economicgeographical analysis of the foreign trade had revealed the diversity of directions and intensity of foreign goods trade between the Belarusian-Russian borderlands, mainly expressed in the predominance of the export-oriented regions with the per capita foreign trade turnover estimated at up to 2000 US dollars.","PeriodicalId":52778,"journal":{"name":"Zhurnal Belorusskogo gosudarstvennogo universiteta Geografiia geologiia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46278612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic criteria for location selection are evaluated using an analytical hierarchy process method based on multi-criteria decision-making technique for large-scale solar photovoltaic projects. The analytical hierarchy process model is also applied to evaluate areas of high solar potential and factors that are primary criteria for determinate the site suitability index modelling. This method considers various conditions, such as production and technological considerations, which aim to maximise the short-term profit from the project and the efficiency of power generation. In the study, a consistency ratio of suitable localities was determined and proper alternatives for the construction of photovoltaic installations were evaluated. In addition to local meteorology and related satellite measurement data, the country’s radiation values also were compared by converting a digital elevation model data using the tool «Area solar radiation» in GIS. As a result of calculating the site suitability index with the ArcGIS weighted overlay tool, it was concluded that 1.17 % (1016.8 km2) of the country are the most suitable sites for the installation of solar PV systems. These areas mainly include Khizi, Gobustan, Hajigabul, Beylagan, Sharur, Babek and Jeyranchol zones. The total number of locations identified accross the country, classified into 3 categories according to their level of suitability, includes 40 sites. Eight of these high suitability sites, all in Nakhchivan Autonomous Republic, contain 11 % (109.2 km2) of the total potential area. The remaining 32 sites, corresponding to areas with medium and low energy potential, cover 28 % (284.6 km2) and 61 % (623 km2), respectively. When these areas are completely covered with PV panels, it will be possible to fully supply the energy demand of the country with solar energy.","PeriodicalId":52778,"journal":{"name":"Zhurnal Belorusskogo gosudarstvennogo universiteta Geografiia geologiia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44200430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The geopolitical concept of space is interpreted as the result of the geopolitical interaction of the latter with the outside world. Its historical development, the nature of organisation and behavior in relation to other geopolitical entities play a decisive role in this regard. The accumulation of these processes over time forms the semantics of stereotypical political ideas about space, such as: mission, security, buffering, a tendency to integrate and interpenetrate attractiveness, conflict, centrality, peripherality, etc., expressing themselves in a geopolitical image. The images of space, which are becoming increasingly important in geopolitical interaction, direct modern geopolitics to a deeper understanding of the status, role and orientation of various entities expressing geopolitics. A system-representative model of the study of the geopolitical image of space as a basis of methodological orientation, presented as the main idea of the study, has been developed. The model synthesises the interaction between the main factors and elements that form the geopolitical vision of space, which are projected onto its image in a dependent relationship. With this model, we defend the idea of launching an algorithm that adequately structures the process of forming a geopolitical image of space. The attributes that determine the formation of the geopolitical image of space have been displayed: factors of perception of space of internal and external character; sources of space perception (social experience and education, art, media products, maps, media); geopolitical identification; geopolitical identity; geopolitical discourse; semantic stratification and the scale of the geopolitical image.","PeriodicalId":52778,"journal":{"name":"Zhurnal Belorusskogo gosudarstvennogo universiteta Geografiia geologiia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47960054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seasonal and long-term values of soil temperature for stable snow period decrease from west to east: a decrease of snow thickness and air temperature from west to east of Eurasia leads to a weakening of the heat-insulating properties of the snow cover with a significant decrease in regional air temperatures. With the emergence of a stable snow cover, the soil temperature seasonal and long-term standard deviation sharply decreases compared to the autumn and spring periods. With the appearance of snow cover, the soil temperature standard deviation drops sharply compared to the autumn and spring periods. An exception is the northeast of Siberia: here, a relatively small thickness of snow determines a noticeable dependence of the course of soil temperature on the dynamics of surface air temperature. There are no significant long-term trends in soil temperature due to its low variability during winter period. Analysis of the course of the studied characteristics anomalies showed an insignificant and non-systematic number of their coincidences.
