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  - This study aims to estimate geothermal potential, radioactivity levels, and environmental pollution of six most popular spas in Central Serbia (Ovcar, Gornja Trepca, Vrnjacka, Mataruska, Bogutovacka and Sokobanja), as well as to evaluate potential exposure and health risks for living and visiting population. Thermal possibilities of the studied spas showed medium and low geothermal potential with total thermal power of 0.025 MW. Gamma dose rates in air varied from 63 to 178 nSv h(-1). Specific activities of natural radionuclides (Ra-226, Th-232 and K-40) and Cs-137 in soil were measured; annual effective doses and excess lifetime cancer risk from radionuclides were calculated. Radon concentration in thermal-mineral waters from the spas ranged between 1.5 and 60.7 Bq L-1 (the highest values were measured in Sokobanja). The annual effective dose from radon due to water ingestion was calculated. The analyzed soils had a clay loam texture. The presence of As, Cr, Cu, Fe, Mn, Ni, Pb, Cd, Zn, and Hg in soil was investigated. The concentrations of As, Cr, Ni, and Hg exceeded the regulatory limits in many samples. Soil samples from Mataruska spa were generally the most contaminated with heavy metals, while the lowest heavy metal concentrations were observed in Sokobanja. Health effects of exposure to heavy metals in soil were estimated by non-carcinogenic risk and carcinogenic risk assessment. Total carcinogenic risk ranged between 6 x 10(-4) and 137 x 10(-4) for children and between 0.1 x 10(-4) and 2.2 x 10(-4) for adults. The sum of 16 PAHs analyzed in soil samples varied from 92 to 854 mu g kg(-1).

AB  - Activity levels of natural and artificial radionuclides and content of ten heavy metals (As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn and Hg) were investigated in 41 soil samples collected from Toplica region located in the south part of Serbia. Radioactivity was determined by gamma spectrometry using HPGe detector. The obtained mean activity concentrations +/- standard deviations of radionuclides Ra-226, Th-232, K-40 and Cs-137 were 29.9 +/- 9.4, 36.6 +/- 11.5, 492 +/- 181 and 13.4 +/- 18.7 Bq kg(-1), respectively. According to Shapiro-Wilk normality test, activity concentrations of Ra-226 and Th-232 were consistent with normal distribution. External exposure from radioactivity was estimated through dose and radiation risk assessments. Concentrations of heavy metals were measured by using ICP-OES, and their health risks were then determined. Enrichment by heavy metals and pollution level in soils were evaluated using the enrichment factor, the geoaccumulation index (I-geo), pollution index and pollution load index. Based on GIS approach, the spatial distribution maps of radionuclides and heavy metal contents were made. Spearman correlation coefficient was used for correlation analysis between radionuclide activity concentrations and heavy metal contents.

AB  - This study was performed in order to investigate gamma dose rates, radon exhalation rates and soil radioactivity with respect to geology. Fifteen locations in three Serbian spas were under investigation. Gamma dose rate was measured by Radex RD1503(+) monitor. GIS technology was applied for the interpretation of the results. HPGe detector was used for gamma-spectrometry determination of soil radioactivity. Radon exhalation rate was determined using RAD7 device. The correlation was examined between radon exhalation rate and Ra-226. No correlation was found between calculated effective dose from radionuclides in soil and measured ambient gamma dose rate.

AB  - Although the Toplica region is situated in a forest-rich part of the Republic of Serbia, the region's four municipalities are not equally forested. Forests are an important resource for economic activities and the existence of flora and fauna, both globally and in the Republic of Serbia. Many initiatives around the world intend to protect and renew forest belts under the sponsorship of developed and developing countries (e.g. China, India, Russia, Brazil, or the G7). In this study, we reconstructed the condition of forests in the Toplica region over the last 60 years using remote sensing, topographic maps, geographical information system (GIS) analysis, and official data from cadaster books and censuses. In addition to changes in forested land, concurrent socio-economic changes have affected the distribution and density of forests. The total number of trees in the Toplica region in 2013 was determined by applying numerical GIS analyses to remote sensing data. We also reconstructed the state of forests in 1953 and used this to determine the total number of trees cut down within this period, as well as the forested areas within different parts of the region. We also determined the elevations beneath different forested zones. In addition to these qualitative and quantitative analyses, we analyzed processes with the potential to influence future forest dispersion (afforestation, deagrarianization, degradation, and deforestation). These analyses are useful in acquiring more detailed insight into the condition of forests in this part of southeastern Europe.

AB  - The monitoring of the territory of Prokuplje Municipality was done based on 1 : 25,000 topographic maps in three different time periods (1969, 1974, and 1984) and land cover map in 2012. Analogous topographic maps done in 1969, 1974, and 1984 were used, while in 2012 the land cover map obtained by using CORINE-like approach was used. Topographic maps are developed by aerial campaign, and today they are replaced by satellite images. Topographic maps were scanned, and raster form was transformed to vector data with Geo Media Professional 6.1 and Global Mapper software. The monitoring in the period of 1969-2012, on the area of 758300000 m(2), was performed, where some parameters were analyzed. In particular, the changes of natural resources, primarily forest lands, were observed as well as the type of land susceptible to primary erosion, including the level of urbanization and level of agricultural land. The obtained results clearly showed changes in forestation within the 43-year-long period, as well as changes in primary erosion and urbanization, while at the level of agricultural land, slight changes were found. The paper also involved transition of social factors from 1969 to 2012, expressed as a change between the earth and forest layer.
