This paper analyzes the basic characteristics of Serbia’s urban system after World War II. The term urban system is largely determined by the use and functioning of the space in which it exists. We used the methods common in urban geography, notably the Rank-Size Rule and the Law of the Primate City with the aim of identifying the basic regularities, as the first step in an in-depth study of an under-researched topic. The research seeks to contribute to explaining the causes of the previous and current situation in the national settlement network, as a prerequisite for planning the future organization of the settlement network. Our study, conducted in Serbia, finds polarization apparent in the prominent domination of the capital city in terms of population, and this is a key feature of Serbia’s urban system. The current situation is the result of an intensive process of urbanization, but also of the establishment of new administrative boundaries after the disintegration of Yugoslavia. The study also seeks to suggest the most appropriate development model for Serbia’s urban system that could help overcome the extreme population concentration in Belgrade and create a basis for organizing an optimal system of centers. Keeping in mind that uneven regional development is determined by the features of the urban system, polycentric development is a common model for overcoming extreme polarization on a global level.
Abstract:Considering recent weather events in Serbia (especially the floods in 2014), a need has arisen for research that would help in identifying extreme weather phenomena. Therefore, the aim of this paper is to determine the thresholds above which intense precipitation can be considered as extreme precipitation events in Serbia. In this study, we determined the frequency of precipitation occurring at an intensity above the threshold of an extreme phenomenon , as well as the frequency of precipitation occurring at or above the absolute daily maximum in the reference period . The study sample included daily rainfall observations from 28 stations from the national meteorological network in Serbia. Applying a decile method, all the stations recording precipitation above the threshold of dangerous phenomena on the same day are classified into the corresponding decile. The threshold value was determined as the average value of the extreme annual precipitation in the analyzed period. The cases that are due to the high prevalence listed in the last decile are considered extreme. The results showed that the critical number of observation points above which an event is considered extreme precipitation event is 6.21, and a warning of the danger could be ensured only in the case of neighboring stations in the network. The threshold of extreme precipitation events for the individual stations ranges up to 130 mm. The obtained results might be used to mitigate the effects of extreme precipitation events in Serbia in the future.
We assessed the influence of environmental values on the proenvironmental behavior of youth in Serbia by assessing the level of their satisfaction with environmental conditions and their sense of personal environmental responsibility. Participants were 168 15-year-old boys and girls who were pupils in their final year at primary schools in Belgrade. We found that 9.5% of the variability in the students' proenvironmental behavior could be explained by individual differences regarding their environmental values, environmental satisfaction, and environmental responsibility. The results obtained from this study should provide curriculum developers, educators, and teachers with a deeper understanding of methods and strategies to use in order to raise environmental awareness and to encourage environmentally responsible behavior among young people in Serbia.
Various socio-historical and cultural influences that have permeated the territory of Serbia have created a specific cultural heritage composed of interesting architecture, spatial and environmental units, folklore, gastronomy, lifestyle, and other specifics, which are usually under protection and are significantly visited by tourists. The value of resources and the state of development determine the overall tourist potential of the area. In this research, two methods were used to assess the tourist potential for six spatial, cultural, and historical units in Serbia: the analytical hierarchical process and the mathematical model, which is based on the du Cros method. The aim of the research is to determine the validity of the obtained results through their comparison and to record the shortcomings. The same indicators and sub-indicators were used in both methodologies, while the weighting coefficients differed according to the methodology. The importance of the research is reflected in the confirmation of the fact that there is a need to develop new methods that would eliminate all the shortcomings and increase the level of objectivity in the assessment of tourism potential.
