AB  - The study aims to present reliable information about thermal conditions and their impacts on visitors to ski travel destinations.Mountain tourism areas are specific since high altitudes affect the ambient weather conditions which can affect different types of human activities. In this paper, the thermal comfort and its changes in Kopaonik Mountain, the most popular ski resort in Serbia over the last 30 years, have been evaluated. Information about thermal comfort is presented by using the Universal Thermal Climate Index (UTCI), physiologically equivalent temperature (PET), and modified physiologically equivalent temperature (mPET) in 3-h resolution for the period 1991–2020. The results indicate prevailing cold stress all year round. Days with moderate, strong, and very strong heat stress were not recorded. Strong and extreme cold stress prevailed during winter, while slight and moderate cold stress prevailed during summer. Transitional seasons were very cold, but autumn was more comfortable than spring. The occurrence of days with neutral and slightly warm/cool conditions is concentrated in the summer months. However, summer is not used enough for tourism because the choice of tourists to stay at Kopaonik is not primarily based on favorable bioclimatic conditions, but on resources for winter tourism. With global warming, the annual number of thermally favorable days has been increasing, while the number of days with extreme and strong cold stress is decreasing. Continuing this trend can significantly influence tourism in the future, and therefore, new strategies in ski resorts will be required to adapt to the changing climate.

AB  - This research is devoted to the determination of hidden dependencies between the flow of particles that come from the Sun and precipitation-induced floods in the United Kingdom (UK). The analysis covers 20 flood events during the period from October 2001 to December 2019. The parameters of solar activity were used as model input data, while precipitations data in the period 10 days before and during each flood event were used as model output. The time lag of 0–9 days was taken into account in the research. Correlation analysis was conducted to determine the degree of randomness for the time series of input and output parameters. For establishing a potential causative link, machine learning classification predictive modeling was applied. Two approaches, the decision tree, and the random forest were used. We analyzed the accuracy of classification models forecast from 0 to 9 days in advance. It was found that the most important factors for flood forecasting are proton density with a time lag of 9, differential proton flux in the range of 310–580 keV, and ion temperature. Research in this paper has shown that the decision tree model is more accurate and adequate in predicting the appearance of precipitation-induced floods up to 9 days ahead with an accuracy of 91%. The results of this study confirmed that by increasing technical capabilities, using improved machine learning techniques and large data sets, it is possible to improve the understanding of the physical link between the solar wind and tropospheric weather and help improve severe weather forecasting.

AB  - The study focuses on the present state and the assessments of geotourism development of the two most representative tufa deposits in the Djerdap National Park—the first UNESCO Global Geopark in Serbia. The findings were designated through implementing the freshly upgraded methodology—M-GAM-1-2 based on an early modified geosites assessment model (M-GAM). To overcome the limitations of the previous model, the authors implemented additional enhancements and involved members of the local community (residents and authorities) in the study to comprehensively evaluate the observed sites. The outcomes revealed that the attitudes of all stakeholders should be taken into consideration in order to develop geotourism properly, additionally attract visitors, and preserve tufa deposits for future generations of locals and visitors. Moreover, geotourism at the observed sites can be one of the vital activities of the population, as well as a type of compensation for various limitations in the development, which are imposed by the regimes of natural and cultural heritage protection within the recently established UNESCO Global Geopark.

AB  - In this paper, a method previously developed for reconstructing daily
erythemal ultraviolet (UVery) doses in Novi Sad (Serbia) was improved and
used for estimating daily UVery over the period 1971–2018. The proposed
new method uses reanalysed total ozone column (TOC) data and snow
cover as an input and is based on the empirical relationship between relative sunshine duration and relative UVery doses. Introducing reanalysed
TOC data and snow cover data significantly improved the quality and accuracy of the reconstructed UVery time series, particularly in the winter season. The reconstructed time series revealed the statistically significant
increase in summer and winter UVery in the 1980s and the first half of the
1990s (+8.78% and + 13.14% per decade, respectively), which was linked to
the statistically significant decline in TOC (−4.13 and −7.36% per decade,
respectively). The study focuses on days with high erythemal UV dose
(highUVery), which is defined based on the 90th percentile of the daily UVery
for each month. Moreover, the influence of low TOC, low cloud cover
conditions, and high surface albedo on highUVery was analysed on a seasonal
basis. The results of this study show that highUVery days increased from
the 1980s, particularly strongly in the period of TOC depletion. A fraction
of highUVery days in the last two decades was large (12.29%), which is higher
than in the previous periods (6.97 and 8.68% in the period before and
during TOC depletion, respectively). The occurrence of highUVery days was
influenced mostly by low cloud cover (89.71% of days), and low TOC
(82.23% of days). In the winter season, high surface albedo influenced the
appearance of 19.18% of highUVery days. However, overall the interaction
of low cloud cover and low TOC in all seasons most often led to the
appearance of highUVery days.

AB  - This study has analyzed the traffic-related change in atmospheric pollutants levels (PM2.5, PM10, CO, NO2, SO2, and O3) caused by the COVID-19 restrictive measures, based on traffic ground-based stations data in urban areas in Serbia. The possible influence of several meteorological factors (temperature, wind, pressure, and humidity), and mobility on the pollutants’ levels were also considered. The obtained results showed a positive correlation of daily NO2 concentrations with mobility and its significant reduction during restrictive measures at all selected monitoring stations. The reduction of NO2 was higher than in other countries (71.1–111.5% for measured, and 49.3–92.6% for ‘deweathered’ data), indicating a high traffic impact on NO2 levels in Serbia. The PM, CO, and SO2 showed a weak correlation with mobility during the period with restrictive measures, which, besides traffic, indicates the significant influence of other sources of their concentration. The O3 concentrations were increased at all measuring stations and are negatively correlated to mobility. Comparison of pollutant concentrations during restriction with the equivalent period in preceding years showed reductions in NO2 and SO2 concentrations. However, compared to previous years, the concentrations of PM2.5, PM10, and CO increased in the period with restrictive measures, indicating lower sensitivity to population mobility and higher dependence on other emission sources. The findings suggest the justification for the use of traffic reduction strategies to improve air quality.

abstract = "This study has analyzed the traffic-related change in atmospheric pollutants levels (PM2.5, PM10, CO, NO2, SO2, and O3) caused by the COVID-19 restrictive measures, based on traffic ground-based stations data in urban areas in Serbia. The possible influence of several meteorological factors (temperature, wind, pressure, and humidity), and mobility on the pollutants’ levels were also considered. The obtained results showed a positive correlation of daily NO2 concentrations with mobility and its significant reduction during restrictive measures at all selected monitoring stations. The reduction of NO2 was higher than in other countries (71.1–111.5% for measured, and 49.3–92.6% for ‘deweathered’ data), indicating a high traffic impact on NO2 levels in Serbia. The PM, CO, and SO2 showed a weak correlation with mobility during the period with restrictive measures, which, besides traffic, indicates the significant influence of other sources of their concentration. The O3 concentrations were increased at all measuring stations and are negatively correlated to mobility. Comparison of pollutant concentrations during restriction with the equivalent period in preceding years showed reductions in NO2 and SO2 concentrations. However, compared to previous years, the concentrations of PM2.5, PM10, and CO increased in the period with restrictive measures, indicating lower sensitivity to population mobility and higher dependence on other emission sources.

AB  - This study aims to indicate the importance of revising current health recommendations concerning the duration of exposure and individual sensitivity of the skin to solar ultraviolet (UV) radiation. For this purpose, a 16-year data series (2005–2020) of erythemal radiant exposure (Her) and UV index (UVI) for Serbia was analyzed. The UV-related risk was estimated for lighter skin (skin phototypes I-IV) under prolonged exposure on days when maximum UVI was below the recommended protection threshold (UVIlow days, for UVI < 3). Risk assessment was performed for seasonal exposure using satellite-derived data (OMUVBd product) previously validated by ground-based measurements in Novi Sad. The assessment of harmful effects included an analysis of the relation between the daily maximum UVI and the corresponding daily Her, the occurrence of UVIlow days, the exceedance of minimal erythema dose (MED), and the minimum duration of exposure to induce erythema (tMED) for all lighter skin phototypes. It was found that the share of UVIlow days in the total number of days in Serbia increases with the latitude, with the highest percentage in winter (up to 69.454%) and the lowest in summer (up to 3.468%). The results show that the daily Her frequently exceeded the harmful threshold for lighter skin phototypes I-IV (on average by 91.521, 84.923, 70.556, and 56.515%, respectively) on UVIlow days. It was found that prolonged exposure on days with a maximum of UVI = 2 poses a significant risk of erythema for all lighter skin phototypes, even for a duration of 3 h in the middle of the day, as well as medium risk for UVI = 1, and an absence of risk for UVI = 0. The results suggest that health recommendations should be revised, especially in the midlatitudes, where the share of UVIlow days is large, and in areas where the population is predominantly lighter-skinned.

AB  - The UV monitoring in Novi Sad has been in operation by broadband Yankee UVB-1 biometer at the campus of the University of Novi Sad (45.33° N, 19.85° E, 84 m above sea level) since 2003. Data of UV index are taken every 30 s, averaged over 10 min intervals, and automatically saved in the database. The time series were reconstructed using an improved reconstruction technique that is based on parametric numerical model NEOPLANTA calculations of erythemal radiation and the empirical relationship between the erythemal doses and sunshine duration. In this study, we presented the maximum daily UV index values over the period 2003-2018 and the variability of reconstructed high erythemal UV doses (hUVery) over the period 1971-2018. Additionally, the influence of low total ozone column (TOC), low cloud cover conditions, and high surface albedo on hUVery was analyzed on a seasonal basis. 
Analyzing the measurements we concluded that maximum daily values are almost the same in the period of sixteen years, in the summer months maximum values are about 9. Based on the 90th percentile of each month we assessed a set of 1691 days with hUVery (10.65 %). The fraction of hUVery days in the last two decades was considerably larger (12.29%) than in the period before (6.97%) and during (8.68%) TOC depletion. We observed a statistically significant increase in the annual number of days with hUVery of +6.26 days/decade (p<0.01). The increase was statistically significant in all seasons, except winter, while it was the most pronounced in summer (+2.44 days/decade, p<0.01).  However, the increase was not uniform over the entire observation period. Over the period of TOC depletion (1971-1980), the number of days with hUVery decreased, followed by a steep significant increase over the period of TOC depletion (1981-1996) of +16.75 days per decade (p<0.05). After 1996 hUVery increased slowly (+3.19 days/decade), but the trend was not statistically significant. Considering the influence of each UV affecting factor separately, the analysis showed that low cloud cover had slightly more influence on the occurrence of hUVery days than TOC in all seasons except winter. Of the total number of hUVery days, 89.47% were recorded when the cloud cover was low, while 80.65% of hUVery were recorded when the TOC was low.  However, the most frequent reason for hUVery is the combination of these two factors (75% of all hUVery days). In the winter season-high surface albedo influenced the appearance of 18.26% of hUVery days.
It is important to emphasize that we analyzed the reconstructed erythemal doses, not the measured data. Reconstructed data (implying the quality of the reconstruction) provide valuable resources for insight into UV variability in the past although cannot replace measurements. The results indicate even if the TOC recovers in the 21st century as expected, the appearance of days with high erythemal doses will still be significantly affected by future changes in the cloud cover.

AB  - Local marketplaces and street vendors represent an important segment of trade in a community and one of the initiators of the rural and peri-urban development. Agricultural and other products available at marketplaces and street vendors very often originate from a wider urban surrounding or nearby villages, so both are also an important factor of the daily migrations, exchange of goods, services, and money on the relation suburb-downtown and village-town/city. This study
aims to analyze the social segments of the organization and operation of marketplaces, to provide an insight into the contemporary market processes and decision-making, and also to illustrate the future tendencies of the market outcomes of this aspect of the business. Using qualitative data processing, the results of one of the first empirical research on this topic in Serbia and this part of Europe will be analyzed. The results will show the economic, social, and cultural impact that marketplaces have on people’s everyday life and the economy of Serbia, along with defining future development guidelines. Besides, the findings of this research may be used by local authorities, the economy, and communities for future strategic development planning of this market segment. The outcomes may have an impact on future research of other aspects of marketplaces depending on the difference of regions, on one side, and also alternative opportunities for local development in less-advantaged communities, on the other side. Moreover, this contributes to the identification of the differences in the marketplace business management and sheds light on future initiatives for the encouragement of this local/global process.

AB  - In this paper, we described generation and performances of feedforward neural network model that could be used for a day ahead predictions of the daily maximum 1-h ozone concentration (1hO3) and 8-h average ozone concentration (8hO3) at one traffic and one background station in the urban area of Novi Sad,
Serbia. The six meteorological variables for the day preceding the forecast and forecast day, ozone concentrations in the day preceding the forecast, the number of the day of the year, and the number of the weekday for which ozone prediction was performed were utilized as inputs. The three-layer perceptron neural network models with the best performance were chosen by testing with different numbers of neurons in the hidden layer and different activation functions. The mean bias error, mean absolute error, root mean squared error, correlation coefficient, and index of agreement or Willmott’s Index for the validation data for 1hO3 forecasting were 0.005 μg m−3, 12.149 μg m−3, 15.926 μg m−3, 0.988, and 0.950, respectively, for the traffic station (Dnevnik), and − 0.565 μg m−3, 10.101 μg m−3, 12.962 μg m−3, 0.911, and 0.953, respectively, for the background station (Liman). For 8hO3 forecasting, statistical indicators were − 1.126 μg m−3, 10.614 μg m−3, 12.962 μg m−3, 0.910, and 0.948 respectively for the
station Dnevnik and − 0.001 μg m−3, 8.574 μg m−3, 10.741 μg m−3, 0.936, and 0.966, respectively, for the station Liman. According to the Kolmogorov–Smirnov test, there is no significant difference between measured and predicted data. Models showed a good performance in forecasting days with the high values over a certain threshold.

AB  - Soil erosion is a global environmental and economic problem that is significantly related to land-use changes. Over the last decades, several mountain areas in Serbia were exposed to strong human pressure caused by winter tourism development. The largest ski center in Serbia is situated on Kopaonik Mountain within the boundaries of Kopaonik National Park, where the conflict between economic and conservation goals is rapidly growing. In this study, we calculated the sedimentation and surface runoff in three sub-basins in the area of Kopaonik ski resort for two years (1984 and 2018) using the Soil and Water Assessment Tool (SWAT) and analyzed the changes that occurred during the observed period. The results show an increase in surface runoff and sediment yield in sub-basins 1 and 3 and a decrease in sub-basin 2. The analysis of land cover change shows an expansion of evergreen forests, appearance of barren soil and urban areas, reduction of mixed forests and pastures, and the appearance of deciduous forests. These findings indicate that in the area studied, the dominant processes are the development of tourism and natural revegetation of abandoned agricultural land. Application of remote sensing techniques and SWAT contributes to identifying and monitoring land degradation problems and improving conservation and management practices.

AB  - A crisis caused by COVID-19 pandemic affected the whole world leaving long-lasting effects on almost every aspect of human lives. The aim of this study was to test how different effects of COVID-19, expressed through job insecurity, employees' health complaints occurred during isolation, risk-taking behavior at workplace and changes in the organization, may impact work-related attitudes (job motivation and job satisfaction) and turnover intentions of the employees in hospitality industry. Based on the data collected from 624 hospitality workers from Serbia, the results indicated that job insecurity and changes in the organization were predictors of all outcomes, in a negative direction, while risk-taking behavior acted as a predictor of job satisfaction only, also in a negative direction. The significance of demographic characteristics, as control variables, showed that age and marital status had significant impact on job motivation and turnover intentions. The theoretical and practical implications were discussed.

AB  - The impact of solar activity on environmental processes is difficult to understand and complex for empirical modeling. This study aimed to establish forecast models of the meteorological conditions in the forest fire areas based on the solar activity parameters applying the neural networks approach. During July and August 2018, severe forest fires simultaneously occurred in the State of California (USA), Portugal, and Greece. Air temperature and humidity data together with solar parameters (integral flux of solar protons, differential electron flux and proton flux, solar wind plasma parameters, and solar radio flux at 10.7 cm data) were used in long short-term memory (LSTM) recurrent neural network ensembles. It is found that solar activity mostly affects the humidity for two stations in California and Portugal (an increase in the integral flux of solar protons of > 30 MeV by 10% increases the humidity by 3.25%, 1.65%, and 1.57%, respectively). Furthermore, an increase in air temperature of 10% increases the humidity by 2.55%, 2.01%, and 0.26%, respectively. It is shown that temperature is less sensitive to changes in solar parameters but depends on previous conditions (previous increase of 10% increases the current temperature by 0.75%, 0.34%, and 0.33%, respectively). Humidity in Greece is mostly impacted by solar flux F10.7 cm and previous values of humidity. An increase in these factors by 10% will lead to a decrease in the humidity of 3.89% or an increase of 1.31%, while air temperature mostly depends on ion temperature. If this factor increases by 10%, it will lead to air temperature rising by 0.42%

AB  - Forest fires that occurred in Portugal on June 18, 2017, caused several tens of
human casualties. The cause of their emergence, as well as many others that occurred in western Europe at the same time remained unknown. Taking into account consequences, including loss of human lives and endangerment of ecosystem sustainability, discovering of the forest fires causes is the very significant question. The heliocentric hypothesis has indirectly been tested, according to which charged particles are a possible cause of forest fires. We must point out that it was not possible to verify whether in this specific case the particles by reaching the ground and burning the plant mass create the initial phase of the formation of the flame. Therefore, we have tried to determine whether during the critical period, i. e. from June 15-19 there is a certain statistical connection between certain parameters of the solar wind and meteorological elements. Based on the hourly values of the charged particles flow, a correlation analysis was performed with hourly values of individual meteorological elements including time lag at Monte Real station. The application of the Adaptive Neuro Fuzzy Inference System models has shown that there is a high degree of connection between the flow of protons and the analyzed meteorological elements in Portugal. However, further verification of this hypothesis requires further laboratory testing.

AB  - This research is devoted to the determination of the causal relationship between the flow of particles that are coming from the Sun and the hurricanes Irma, Jose, and Katia. To accomplish this, the lag correlation analysis was performed. High correlation coefficients confirmed a preliminary conclusion about the relationship between solar activities and the hurricane phenomenon, which allows further research. Five parameters i.e. characteristics of solar activity (10.7 cm solar radio flux (F10.7), the flows of protons and electrons with maximum energy, speed and density of solar wind particles) were chosen as model input, while the wind speed and air pressure of Irma, Jose, and Katia hurricanes were used as model output. Input data were sampled to a six hours interval in order to adapt the time interval to the observed data about hurricanes, in the period between September 28 and December 21, 2017. As a result of the preliminary analysis, using 12,274,264 linear models by parallel calculations, six of them were chosen as best. The identified lags were the basis for refinement of models with the artificial neural networks. Multilayer perceptrons with back propagation and recurrent LSTM have been chosen as commonly used artificial neural networks. Comparison of the accuracy of both linear and artificial neural networks results confirmed the adequacy of these models and made it possible to take into account the dynamics of the solar wind. Sensitivity analysis has shown that F10.7 has the greatest impact on the wind speed of the hurricanes. Despite low sensitivity of pressure to change the parameters of the solar wind, their strong fluctuations can cause a sharp decrease in pressure, and therefore the appearance of hurricanes.

AB  - The long-term exposure to PM2.5 (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 PM2.5 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 PM2.5. The mean annual values vary in the range 13.93 μg/m3 –28.91 μg/m3 . The regional differences exist, but the highest values were obtained for urban environments (> 22.5 μg/m3 ). Negative trend of annual PM2.5 is present in most of the parts of the Serbian territory, especially in the eastern parts reaching –0.37 μg/m3 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/m3 ), but comparing to the World Health Organization (WHO) guideline (10 μm/m3 ), 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 PM2.5. The share of the population exposed to values higher than 25 μg/m3 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.

AB  - In this work we study the potential of C-band SAR images to map ionosphere disturbances
in the Arctic region. This region is a unique region for ionosphere studies due to the characteristics of the geomagnetic field. In particular, we focus on the SAR interferometry technique as means to measure the temporal variation of propagation delay in correspondence of ionosphere disturbances. This technique provides maps of propagation delay differences between the acquisition dates of the two coherent SAR images needed to estimate the propagation delay over the study area. The high spatial resolution of C-band SAR images, in the order of 25 meters could contribute to the study of spatial distribution of ionosphere disturbances. Digisondes, VLF/ELF receivers and the EISCAT radars in the available in the Arctic region provide the time of ionosphere disturbances due to the solar activity, monitored by the ACE satellite. This allows to select the SAR images to process to map the ionosphere disturbances. The typical spatial coverage and acquisition times of Sentinel-1 images over the Arctic region are reported. A numerical analysis is carried out to estimate the expected ionosphere propagation delay in Sentinel-1 interferograms and so the potential of SAR interferometry to map the effects of ionosphere disturbances.

AB  - The research analyzes attitudes and habits of the visitors in the National Park (NP) Taganay on South Urals in Russia. The survey method was applied on a sample of 305 respondents in order to investigate visitors’ travel habits, as well as their perceptions regarding different experiences they were exposed to. The results identified a strong positive perception regarding overall experiences from visiting the NP. Specific permanent patterns of behavior were observed and compatibility between visitors’ habits and the environment was determined. The most significant variables affecting perceptions are the frequency of visits and the age. The study has identified certain concerns regarding environmental issues. Respondents were found sensitive to garbage production in public areas and the presence of noise in protected territory. The results of the study provide inputs for solving the long-standing conflict between nature conservation and mass tourism in Russian protected areas.

AB  - In this paper we present an analysis of parameters describing the effective recombination processes in the upper ionospheric D-region in the period of its additional heating by the X-radiation emitted during a solar X-ray flare. We present a procedure for calculation of the effective recombination coefficient and electron loss rate in the period when the X-radiation flux detected by the GOES satellite in the wavelength domain between 0.1 and 0.8 nm increases. The developed procedure is based on observational data obtained in the low ionospheric monitoring by the very low/low frequency radio waves and it is related to the considered area and time period. The obtained expressions are applied to data for the very low frequency signal emitted in Germany and recorded in Serbia during the solar X-ray flare detected by the GOES-14 satellite on May 5, 2010.

AB  - Solar ultraviolet (UV) radiation is a significant health hazard in the warm part of the year. In order to assess the level of hazard and the effects of UV radiation on the living world, long-term measured or estimated data are needed. In Novi Sad measurement of UV radiation has been performing since 2003, while ozone measurements are made since 2007. However, those data sets are too short for assessing long-term biological effects. Therefore, several techniques for reconstruction of UV radiation doses are developed. Reconstruction techniques were based on using available ground-based measurements of the meteorological data and satellite measurements of total ozone column. It is shown that techniques that use ozone data show better performance than those that use only ground-based meteorological measurements. However, the difference between the performances of the methods is smaller when it comes to the monthly values, indicating that the techniques which use only ground-based meteorological measurements are roughly as good as the ozone-based techniques for assessing long-term changes in the surface UV radiation. The statistical significant increasing long term-trend of annual mean erythemal UV doses (ERY) and the decreasing trend in total ozone column in Novi Sad since 1981 have been noticed. An increase in ERY was noticed in all seasons except in autumn and it was the highest in winter. The analysis showed that the increase in the ERY in the period 1981-1996 is mainly caused by the total ozone column, while the increase after 1996 is largely caused by cloudiness.

AB  - The purpose of this study is to investigate the potential for restructuring industrial areas toward tourism development within local communities, with a special emphasis on the socio-cultural determinants of residents, as well as their attitudes regarding the sustainable development of tourism. The research is also oriented toward the interests of local communities with respect to entrepreneurial activities in the field of tourism within regions relying on traditional industries, in this case, one of the largest open-pit mining surfaces in Europe (near the Serbian town of Lazarevac). The survey was conducted on a sample of 273 respondents. The research results point to the residents’ attitudes regarding the acceptability of tourism development options, as well as their attitudes toward tourism development, with the aim of providing the conditions for a successful transition from a typical heavy industrial setting toward sustainable tourism development.

AB  - This study investigates the relationship between the quality of hospitality services and sustainable equestrian tourism development in Slovenia. The focus will be on the relations between equestrian tourism motivations, hospitality services quality, overall service quality, equestrian tourists’ satisfaction, and behavioral intentions. The target population was equestrian tourists who stayed in one of 30 tourism farms in Slovenia and used both accommodation and food and beverage services. Face-to-face surveys with convenience sampling were used for the data collection. The results show that equestrian tourism motivations are positively associated with both hospitality services quality and the overall service quality in equestrian tourism. Moreover, the overall service quality in equestrian tourism is positively related to equestrian tourists’ satisfaction, while equestrian tourists’ satisfaction is positively related to behavioral intentions. In addition, accommodation service quality and food and beverage service quality both mediate the association between equestrian tourism motivation and overall satisfaction. The study provides both theoretical and practical implications. For one thing, it fills the research gaps present in the literature. In addition, it gives practical guidelines to farmers and tourism practitioners regarding equestrian tourism development as one of the popular areas of sustainable tourism development in rural settings.

AB  - The atmosphere is a very sensitive medium to extraterrestrial forces, most importantly, solar electromagnetic radiation and energetic particle intrusion. This released intense solar activity can
cause sudden disturbances in the Earth’s atmosphere and further create ground telecommunication interferences, blackouts, transportation problems, water supply problems, potential health effects, as well as natural disasters, such as forest fires. These extreme events can cause billions of dollars of damage and impact individuals, families, communities, and societies. For this reason, it is of crucial importance to investigate the connections between this extreme activity and natural disasters, and further develop ways to prevent, prepare against, and respond to them. The aim of this special issue is to engage a wide community of scientists to de-fragment broaden and improve our knowledge in this field. We invite researchers from all relevant fields to publish their recent investigations in this special issue.

AB  - The manuscript is devoted to analysis of the problem of designing graphical
geoportal interfaces. The support points for the problem solutions are formulated and
rationale of each of them is given. The emphasis was placed on the following
orientations: to a flexible process of interface development, the need to introduce
adaptability, progressive development, the motivated abandonment of geospatial
content management systems and the use of third-party libraries where necessary,
problem-solving and achieving goals. The lists of basic functional and qualitative
requirements for graphical geoportal interfaces are given. In the last segment, the
authors share their experience in the development of geoportal solutions.
