AB  - The Juzna Morava basin covers an area of 15,469 km2, its surface area and hydrological peculiarities require constant research. Imbalances of small, medium and large waters, torrential and erosive events are frequent. Average flows are statistically obtained values, which are most often used in practice when analyzing and preparing studies for further monitoring purposes The non-parametric Mann-Kendall test and Sen’s slope estimation were applied for trend observation, and the Pettit test was used to determine the breaking point in the analyzed time series. Data collected on the hydrological profile of Mojsinje (Juzna Morava) in the time interval 1961-2020 were processed The average annual flow (Qavg) is the most important hydrological indicator for observing trends in longer time series; mean monthly and seasonal flows were also analyzed. Based on the applied tests, it was determined that the water level on the hydrological profile decreases (0.70m3/s/year) without statistical significance, while the results obtained for May are the most significant (-2.10m3/s). The breaking point of the average discharges for most of the data series was recorded in the early 1980s (1982–1984), which coincides with the pluviometric regime in the basin. The analysis of seasonal hydrological events in the basin shows negative trends, most significant in winter. In order to determine wet and dry years, they have been classified according to water richness using the SDI index.

AB  - Climate elements are one of the most important factors for tourism development. This study aims to show the values of the tourist climate comfort index based on monthly values. For the needs of the research, the method of tourist climate comfort (TCCI) was used, on the example of the city of Novi Sad. Meteorological data for the climatological period of 30 years (1991–2020) from the meteorological station Rimski Šan?evi were analysed. Meteorological data that were observed, analysed, and statistically processed are: mean monthly air temperature, monthly temperature amplitude, mean monthly humidity, monthly insolation, and number of rainy days. The obtained results indicate that May and September are the most climatologically suitable months for tourist activities. Data on the number of tourist arrivals and their overnight stays in this area covers the period from 2004-2020. In this paper, a linear correlation between the value of climate comfort and the number of tourists has been made in order to provide local authorities and tourism organizations a more precise overview of the perception and valorisation of climate elements for the improvement of tourist potential.

Ова студија има за циљ да прикаже вредности туристичког климатског индекса комфора на основу месечних вредности. За потребе истраживања коришћена је метода туристичког климатског комфора (TCCI), на примеру града Новог Сада. Анализирани су метеоролошки подаци за климатолошки период од 30 година (1991–2020), са метеоролошке станице Римски Шанчеви. Метеоролошки подаци који су сагледани, анализирани и статистички обрађени су: средња месечна температура ваздуха, месечна температурна амплитуда, средња месечна влажност ваздуха, месечна инсолација и број кишних дана. Добијени резултати указују да су месеци мај и септембар климатолошки најпогоднији за туристичке активности. Подаци о броју долазака туриста и њихових ноћења на овом простору обухватају период од 2004-2020 године. У раду је извршена линеарна корелација између вредности климатског комфора и броја туриста, како би се локалним властима и туристичким организацијама пружио јаснији приказ у сагледавању и валоризацији климатских елемената за потребе унапређења туристичког потенцијала.

AB  - Snow avalanches are one of the most frequent natural hazards in high mountain regions. In this study, a map of the susceptibility of the Šar Mountains to snow avalanches was determined. The study area is located in the southern part of Serbia, which has the Status of a National park. Geographic information systems (GIS) and remote sensing are used to analysis and cartographical presentation of nine the most important elements of natural conditions which have an influence on avalanche development. Then, by applying the best-worst method (BWM) for each of the criteria was given a weighting coefficient depending on its importance for the avalanche occurrence. A synthetic map of snow avalanche susceptibility was created by processing geospatial data in the GIS software. The obtained results show that high susceptibility covers 16.9% of the territory, while 10.7% of the total area is very highly susceptible. The final results may be useful to decision-makers, local self-governments, emergency management services, and mountaineering services to mitigate human and material losses from snow avalanches. This study is the first to use the BWM methodology for snow avalanche hazard analysis.

AB  - The most significant effects of climate change are related to temperature and precipitation. Changes in precipitation and temperature patterns affect water resource capacity, agricultural activities, global biodiversity and emergency management. In this study, using two statistical models (Mann-Kendall and Pettit’s test), climate data for the territory of Belgrade in the time interval 1961-2020 were processed. Trends were analyzed: average annual temperatures, average monthly temperatures, annual and monthly precipitation amounts. The aim of the research is to determine the statistical significance of the increasing/decreasing temperature and precipitation trends on a monthly and annual basis. Based on the obtained results, it was determined that the changing point of the annual temperature is in 1997, while a statistically significant increasing trend was observed in all months except November. The increasing trend recorded by the precipitation amount is 0.345 mm/year, but without statistical significance. The most significant results corresponding to July and October.

AB  - The development of climate indices and their application can influence the preferences of tourists and the time frame for visiting the locality. This study develops a new Heritage Climate Index (HERCI) that finds its application in assessing climate comfort for visiting geoheritage and cultural heritage objects. The study analyzed the geoheritage site in Western Serbia (Stopića Cave) and the cultural heritage site in Eastern Serbia (Golubac Fortress). The index was developed to represent climatic comfort on a monthly basis and consisted of five climatic elements. The values of the HERCI index were obtained based on the multi-criteria decision-making model—the Best–Worst method (BWM). The results were classified into five classes, depending on the degree of conformity. After a comparative analysis of the index results for four localities and their attendance for the period 2012–2021 and 2019–2022, it was determined that there is a very high level of correlation (>0.9). This is the first study to use the BWM to develop and analyze a climate index. From the aspect of tourism policy, this study significantly contributes to tourism organizations and tourists in better understanding climate comfort and making decisions about the organization’s time frame and realization of the travel.

AB  - Zaštita životne sredine je jedna od najaktuelnijih tema današnjice. Prisutni negativni uticaji su rezultat nekontrolisane upotrebe prirodnih resursa, energije, ali i zanemarivanja zakona prirode. Prilagođavanje prirode čovekovim potrebama dovodi do promena koje često izazivaju složene posledice. Eksploatacija uglja na prostoru velikih rudarskih basena kao što je kolubarski ugljeni basen, dovodi do konflikta između rudarskih aktivnosti i postojeće sredine. Nastaju veliki ekološki, geomorfološki i hidrološki poremećaji koji utiču na funkcionisanje postojećih predela i ekosistema. U radu se analiziraju sve direktne i indirektne implikacije otkopavanja uglja na životnu sredinu i mogućnost njihovog smanjenja, odnosno dovođenja u prihvatljive okvire. Ispituju se i najbolja rešenja za povratak terena koji su ostali degradirani nakon eksploatacije uglja u prvobitno stanje ili uspostavljanje neke druge pogodne funkcije. Ekonomski aspekt kao jedan od važnih činilaca kvaliteta života, često je u konfliktu sa očuvanjem zdrave životne sredine. Najveći izazov je uspostaviti ravnotežu između neophodne degradacije i narušavanja kvaliteta životne sredine u cilju obezbeđenja ekonomskih uslova života ljudi, sa jedne strane, i očuvanja životne sredine sa svim resursima, sa druge strane.

abstract = "Zaštita životne sredine je jedna od najaktuelnijih tema današnjice. Prisutni negativni uticaji su rezultat nekontrolisane upotrebe prirodnih resursa, energije, ali i zanemarivanja zakona prirode. Prilagođavanje prirode čovekovim potrebama dovodi do promena koje često izazivaju složene posledice. Eksploatacija uglja na prostoru velikih rudarskih basena kao što je kolubarski ugljeni basen, dovodi do konflikta između rudarskih aktivnosti i postojeće sredine. Nastaju veliki ekološki, geomorfološki i hidrološki poremećaji koji utiču na funkcionisanje postojećih predela i ekosistema. U radu se analiziraju sve direktne i indirektne implikacije otkopavanja uglja na životnu sredinu i mogućnost njihovog smanjenja, odnosno dovođenja u prihvatljive okvire. Ispituju se i najbolja rešenja za povratak terena koji su ostali degradirani nakon eksploatacije uglja u prvobitno stanje ili uspostavljanje neke druge pogodne funkcije. Ekonomski aspekt kao jedan od važnih činilaca kvaliteta života, često je u konfliktu sa očuvanjem zdrave životne sredine. Najveći izazov je uspostaviti ravnotežu između neophodne degradacije i narušavanja kvaliteta životne sredine u cilju obezbeđenja ekonomskih uslova života ljudi, sa jedne strane, i očuvanja životne sredine sa svim resursima, sa druge strane.",

AB  - Climate change are one of the most significant global challenges in the 21st century. Air temperature and precipitation as the most important climatic elements, are the most frequently analyzed parameters. Climate change is not only the cause of global warming, but also brings extreme low and high temperatures, heavy rainfall and other meteorological anomalies. One of the main signals indicating climate change is the change of extreme temperatures. In order to gain insight into the changes in the temperature regime in Belgrade, the number of characteristic days - frost days (FD), ice days (ID), summer days (SU), and the number of tropical nights (TR) over a period of 60 years - was analyzed. The extremes are examined, i.e. the change in the number of days when the daily minimum or maximum temperature is below zero (frost and ice days) and the change in the number of days when the maximum temperature exceeds 25℃ (summer days). Two non–parametric statistical tests were used to determine the trend and the trend magnitude of the selected indices. The Mann-Kendall test was used for trend analysis and the Pettit’s test was used to detect significant changes in the time series of climatological data. The study area is Belgrade, the capital of the Republic of Serbia. The data of the Hydrometeorological Institute of the Republic of Serbia (RHMZ) measured at the weather station Belgrade (Serbia) during two climatological periods 1961-1990 and 1991-2020 were used. The obtained results indicate that the number of frost and ice days decreases, while the number of summer and especially tropical nights increases. According to the applied Mann-Kendell test, statistically significant changes were found in all data series, while the Petitt's test indicated that sudden changes in parameter values began in the late 1980s.

AB  - Forest fires and landslides represent very frequent natural disasters in Serbia.
The Svrljiški Timok river basin is located in the southeastern part of the Republic of Serbia,
and according to natural characteristics it represents a significant area for geohazard study.
The task of the research is to analyse natural and anthropogenic condition by determining
locations which are susceptible to forest fires and landslides in order to protect the population
and infrastructure. Using Geographic Informational Systems (GIS) and available data,
their processing was started for the susceptibility of the terrain to forest fires using the RC
index. For the analysis of the territory occurrence of landslides the statistical Probability
method (PM) and Landslide Susceptibility Index (LSI) were used. The obtained results indicate
that 20.81% of the area of the Svrljiški Timok basin has a very high susceptibility to
forest fires, while 29.21% of the terrain is highly susceptible to landslides. The results
gained processing the RC index can be applied to adequate risk management of forest fires,
improvement of monitoring and early warning systems in the study area. Sustainable management
of agricultural land and improvement of environmental protection can be implemented
on the basis of the obtained results for the most endangered areas of landslides.

AB  - In this paper predisposition of the terrain for the emergence of torrents by application of Geographic Informational Systems (GIS) was made. Due to great ecological importance of this area, it is necessary to continuously monitor the state of the environment. High rainfall over a short period of time is the main cause of torrential floods, and because of the high elevation of Vlasina, the average annual rainfall exceeds 800 mm. The method used to determine the predisposition of a landscape of exceptional qualities (LOEQ) "Vlasina" on occurrence of torrential flood is the Flash Flood Potential Index (FFPI). To identify the possibility of torrential floods occurence, natural conditions were analyzed: slope of the terrain, types of geological substrate, vegetation density and the way the land use. Using the GIS tool, a map of the susceptibility of terrain to the occurrence of torrents in the territory of LOEQ "Vlasina" was obtained, and the classification of rivers was made based on the probability of occurrence of torrential floods on them.
