Farm tourism is often considered a form of tourism whose main characteristic is sustainability. Nevertheless, the existing literature also provides a partial approach, where the development of farm tourism is analyzed within the context of sustainable development and crisis situations, such as the COVID-19 pandemic. The aim of the paper is to analyze environmental, social, and economic factors as vectors for the sustainable development of farm tourism by applying a specially designed SFT model. An empirical study was carried out on a sample of nine farms in the peri-urban area of the city of Novi Sad (the Republic of Serbia). Sustainable development was analyzed using dynamic social, economic, and environmental indicators with the aim of finding a model that could be used to ensure more stable economic income for the population, social equality, and environmental protection. By applying the SFT model, it was determined that the current position of farm tourism is not fully compliant with the aims of sustainable development due to its clearly dominant economic dimension and less developed social and environmental sustainability. The results were further analyzed with the aim of achieving a balanced development of farm tourism, which needs to be based on the continued application of the concept of sustainability. The results could be used by public and private institutions in the tourism sector, as well as creators of legal regulations and strategies in the field of sustainable and rural tourism, with the aim of further developing and improving its sustainability.

Due to rapid urbanisation, urban microclimate research has become increasingly popular in the last decade. Significant variation in microclimate conditions can be created due to diversity in urban geometry and it can affect outdoor thermal comfort. Biometeorological measurements and survey were conducted in different urban settings (square, park, street) of the city of Novi Sad during a warm autumn day in October 2019. Air temperature, relative humidity, wind speed and globe temperature, but also outdoor thermal comfort indices such as Mean Radiant Temperature (Tmrt) and Physiological Equivalent Temperature (PET) were obtained for each location. The largest differences in the biometeorological conditions are noticed between the urban park and other urban areas. The maximum average value of Ta was at the city square with 27.9 oC, while in the urban park and street Ta were about 25 oC. The values of RH were the lowest at the city square. Globe temperature (Tg) had the highest values, on average, at the city square (about 40 oC), while the average values in the urban park and street were about 26-28 oC. The highest average PET values are registered at the city square (41.4 oC), followed by substantially lower average PET registered in urban park (27.1 oC) and urban street canyon (26.2 oC). The analysis showed that during about 70% of the time, urban dwellers experience extreme heat stress at the city square. Contrary to that, no extreme heat stress is noticed in urban park and street canyon.

A Water Quality Index (WQI) is a numeric expression used to evaluate the quality of water bodies and make it easier understood by managers. This paper aims to assess water quality of Sava River in Vojvo­dina (North Serbia) for the 2004 - 2011 period. For this purpose authors applied: Serbian Water Qual­ity Index (SWQI) assessment. WQI value is dimensionless, single number ranging from 0 to 100 (best quality) derived from numerous physical, chemical, biological and microbiological parameters. For the Sava River SWQI was mainly rated as very good. This study shows a clear decrease in water quality dur­ing warmer periods of the year. Additionally, this study shows that water quality along Sava River de­creases slightly downstream, of Sremska Mitrovica station but it still provides values that according to SWQI descriptive quality indicator have been defined as good (72-83) and very good (84 - 89). Also, this study shows an increase of SWQI downstream of the confluence of Drina River into Sava River. This methodology includes parameters for assessment of organic loading, but does not involve parameters of heavy metals concentration.

In the last two decades, artificial light at night has increased at alarming rates on global level and numerous negative effects of excessive artificial lighting are characterized as light pollution. However, light pollution has not gained enough attention such as water or air pollution, even though researchers are finding more and more evidence of its adverse impact on the environment. This phenomenon is mostly unknown in Serbia (and wider region), and consequences of light pollution have not yet been assessed. Autonomous Province of Vojvodina has 165 protected areas which cover a surface of approximately 2048 km2 and are home to a large number of strictly protected species. Furthermore, due to its geographical location and characteristics of the relief, Vojvodina is intersected by numerous ecological corridors, especially for avifauna. Likewise, this region is also highly populated and has dense road network which is usually located nearby protected areas. Since artificial lighting is present wherever there are human activities, it can be assumed that protected areas and ecological corridors in Vojvodina Province are endangered with light pollution. The aim of this paper is to present the basic concept of light pollution problematic, and to define the biggest light emitters in Vojvodina and surrounding in order to outline the most endangered protected areas by this pollutant.
