Renewable energy sources (RES) have the possibility to regenerate in a shorter time interval than the non-renewable energy sources and that is why they have always been the subject of interest, especially in the last decades. The Republic of Serbia has RES in the form of solar, wind, the power of water flow, geothermal heat, and biomass. The scientific research conducted in July 2016 in Temska village (City of Pirot) aimed to assess inhabitants’ attitudes and awareness of using RES. By interviewing 167 respondents, it is concluded that inhabitants do not have sufficient knowledge of quality and information on RES. Mostly, they are familiar with all terms: hydropower, solar, wind and geothermal energy (over 80%), and the term of biomass energy as well (70.7%). There is an extremely high level of misinformation about the RES subventions that are provided by the Government of the Republic of Serbia (up to 85.6% of respondents are not informed). These subventions are published in the Regulation on incentive measures for the production of electricity from RES and are based on the Feed-in Tariff system that is defined as non-refundable financial assistance from the state. A small number of respondents use RES, but a considerable number (21.6% ‘yes’ and 47.3% ‘maybe’) that does not use RES is interested, or already planning to use it in the future.

The anthropogenic activity creates a significant negative impact on the steppe biome of the Earth. Eurasian steppe is one of the most altered by human economic activity, particularly in Russia. These changes are especially vividly manifested in the Russian Plain, the old-developed territory of Russia. The most substantial damage on steppe landscapes of the Russian Plain was caused by the extensive agricultural use of natural grasslands, especially in the second half of the 20th century. The overwhelming majority of natural steppe landscapes are replaced here by agricultural landscapes which threaten the preservation of the unique soil, biological and landscape diversity of steppes. The main goal of the article is to analyze the current geoecological situation in the steppe zone of the Russian Plain from the regional aspect: by the example of its south-eastern part attributed to the Volgograd region. The described territory is characterized by the extraordinary landscape diversity and located within forest-steppe, steppe and semi-desert natural zones. The article deals with the analysis of the current agricultural structure in the south-east of the Russian Plain within Volgograd Region, of major geoecological consequences of economic activity typical of different types of agricultural lands, and also of pressing problems related to the preservation of the landscape, and of the biodiversity of steppe landscape. The results of this research are necessary to make decisions aimed at optimizing agriculture, at raising the quality of steppe landscape preservation, and at organizing ecologically-conscious recreational activity to preserve the unique variety of steppe landscapes.

Even though legally protected, many areas worldwide are under a certain level of human pressure. Significant for humanity for many reasons, mountain regions are also threatened because of different anthropogenic activities, especially the ones with developed winter tourism. There are four main ski resorts in Serbia (Kopaonik, Zlatibor, Stara Planina and Brezovica) and the strongest environmental impact is registered on Kopaonik Mountain. In this paper, we tried to answer if winter tourism could be sustainable in protected areas, especially on Kopaonik Mountain, which is recognized as the largest ski resort in Serbia and a natural protected area of the highest state level—a National Park. The main threats to the environment in Kopaonik National Park are logging, building and construction of ski slopes, urbanization, artificial snow use, illegal and unplanned building. Negative consequences of winter tourism development are land degradation, deforestation, loss and fragmentation of natural habitats, ecosystem disturbances, erosion, soil loss and pollution, water and air pollution, noise and light pollution. Harmonizing tourism development with conservation activities within natural protected areas is one of the main priorities of sustainable use of natural values and resources. For the successful and sustainable development of an area, it is necessary to conduct multidisciplinary planning, based on the results from the relevant scientific disciplines.

The paper investigates the spatial distribution of the seasonal and annual precipitation in Bosnia and Herzegovina. The mean monthly precipitation data from 40 meteorological stations covering the standard climatological thirty-year period (1961−1990) were used for the analysis. Seven precipitation-based parameters were used to regionalize climate in Bosnia and Herzegovina by using the Principal Component Analysis and clustering techniques. The spatial patterns of precipitation were determined by using the R-mode principal component analysis with varimax rotation. The first two principal components, which describe 97.60% of the total variance, were taken into consideration. The varimax rotated scores were subjected to the Cluster Analysis in order to identify homogeneous precipitation regions over the territory of Bosnia and Herzegovina. The agglomerative hierarchical clustering identified three sub-regions with different precipitation regimes. The complex orography, i.e., the influence of the Pannonian Basin, the Dinaric Alps, and the Adriatic Sea, is one of the most decisive factors that affect spatial patterns of precipitation in Bosnia and Herzegovina.

This article investigates the changing concentrations of population and economic activity in the largest regional capitals during the socio-economic transformations at the turn of the millennium. The study focuses on million-plus administrative centers of Russian regions (federal subjects). In post-socialist and developing countries, population and economic activities tend to be increasingly concentrated in the regional capitals, which now occupy the leading positions among other second-tier cities in the national settlement system. The authors explore the reasons behind this trend and propose a methodological approach to assess the population concentration and economic activity in the largest regional capitals and compare these figures with those of the national capitals. In the empirical part of the study, the cities’ performance is assessed by applying a set of indicators, such as population size, production output, retail turnover, investment, and construction output, and compared with corresponding figures from Moscow and St. Petersburg. As a result, large regional capitals are classified according to their role in the country’s socio-economic performance and according to the disparities between these cities and Moscow and St. Petersburg. It was found that none of the largest regional capitals are able to compete with the country’s current and former capitals. Moreover, this gap has been widening over the last decade as the role of regional capitals in national economic development has been steadily declining. However, there are some positive dynamics, as some regional capitals have been outperforming the national average in certain spheres of socio-economic development.

The term “smart city” has recently become greatly widespread in academic and political discourse. Nevertheless, this is rather a marketing term that unites a number of technological (and other) areas: Internet of Things (IoT), augmented and virtual reality (AR/VR), communication networks. The latest generation of networks is essential for the development of digital ecosystems of smart cities. It has been assumed that the smart city and 5G networks form an emerging technological area. The goal of the work is to study the structure of the development and implementation of new technologies for the urban environment on the sample of 5G-based technologies. For the analysis of new technologies in the selected subject area, a study of patent landscapes and scientometric analysis of the topic field has been conducted. The object of the scientometric analysis is the study of citation patterns. The use of the patent landscape is based on the information systems and databases of patent information developed by patent offices and commercial companies and consists of visualizing the logical connections between various indicators of patent activity, on the one hand, and technological and market trends, on the other. Together, the scientometric and patent landscape show the most promising areas of technological research. The results of the study can be used in further theoretical and applied research, in the formation of government policy in research and development, as well as in decision-making in the field of urban management.

The long-term exposure to PM 2.5 (particulate matter with aerodynamic diameter ≤ 2.5 μm) is the leading global health risk factor. The spatio-temporal variability of annual values of the total PM 2.5 concentrations in Serbia is analyzed using the high-resolution (0.01° × 0.01°) gridded data set V4.EU.02 for the period 2001–2016. Population counts and density data were used to calculate the population exposure while the urban land cover data were used to estimate the relations between the size of urban area and the concentration of PM 2.5 . The mean annual values vary in the range 13.93 μg/m 3 –28.91 μg/m 3 . The regional differences exist, but the highest values were obtained for urban environments (> 22.5 μg/m 3 ). Negative trend of annual PM 2.5 is present in most of the parts of the Serbian territory, especially in the eastern parts reaching –0.37 μg/m 3 per year ( p ≤ .05). More than 99% of the territory of Serbia has the mean annual values under the national safe limit established by regulation (25 μm/m 3 ), but comparing to the World Health Organization (WHO) guideline (10 μm/m 3 ), all the territory is above the safe level. In line with the trend of urbanization, there is a clear upward trend in the number of population exposed to the higher concentrations of PM 2.5 . The share of the population exposed to values higher than 25 μg/m 3 increased from 6.65% in 2005 to 11.40% in 2015, while comparing to WHO standard, the total population in Serbia is exposed to the values higher than the safe one.

The Special Nature Reserve "Zasavica" is a significant wetland and Ramsar site of the southwestern part of Vojvodina Province (Northern Serbia). This complex of aquatic habitats has been formed by the effects of the Sava and the Drina rivers. This former riverbed of the Sava River and the today’s Zasavica stream makes the basic hydrographic resource of this protected area. The reserve is inhabited by numerous rare and endangered plant and animal species, which unitedly make rare biodiversity, unique in the country and the region. Whether the area of the Special Nature Reserve “Zasavica” represents a significant potential for the development of tourism will be concluded in this paper by using two scientific methods. The obtained results from a conducted questionnaire, as the first method, will be used to analyze the interplay of factors and their interrelations as potentials for sustainable tourism development, outlined in the Sustainable Tourism Development Strategy of Serbia.The obtained results can examine the main hypothesis that the SNR is a significant tourist potential for ecotourism both at the level of the Republic of Serbia and at the level of the countries in the region, such as Hungary, Romania, Bulgaria, Croatia, Bosnia and Herzegovina, as well as other European countries. By enhancing sustainable tourism and protecting the space of this reserve, and by implementing the national tourist offer, higher socio-cultural, economic and ecological benefits can be achieved.

This paper's frame of reference is tourism marketing, evaluating the image of targeted travel destination from the gender standpoint. For emerging destinations in south-eastern Europe like Serbia, latent connections between destination image and gender are therefore of particular interest for exploration. The International Travel Trade in Berlin (ITB) was the venue for the research. The connections between ITB visitors' gender and the image they perceived about Serbia were assessed, crossed with their socio-demographic attributes, annual travel spending, information sources, association and awareness of Serbia. In this way, the authors wanted to observe and explain the perception of this target group of Serbia’s image. The findings suggest that men and women do not differ in attitudes related to the country's image. On the other hand, there is a difference in image scores for positive, negative and no associations of Serbia. The research results could help in modifying tourism strategies for Serbia.

In this work we used the observed additional perihelion precession in the Solar System, obtained from the observations of planets and spacecrafts, to study the possible existence of Yukawa correction term to the Newtonian gravitational potential. Our study was motivated by previous analyses which indicated the possible discrepancies from Newtonian gravity in this form and at wide range of astrophysical scales. Yukawa gravity was introduced to cure some shortcomings of General Relativity (GR) at galactic and extragalactic scales. We demonstrated that this form of gravity can give the values for orbital precession which are comparable or even in better agreement with observations than the corresponding predictions of GR. The obtained results can be used for setting stronger constraints on variation of the gravitational constant G, as well as on the fundamental constant δ of Yukawa gravity. Moreover, Yukawa gravity could be used to improve the results for the motion of planets, other Solar System bodies, as well as spacecrafts, and as a consequence, it can help us to get more reliable predictions for natural hazards in the Solar System, such as potential impacts by near-Earth objects.
