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 (1961–2015), as well as the frequency of precipitation occurring at or above the absolute daily maximum in the reference period (1961–1990). 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.

Taking into account the fact that intensifying problems concerning the environment, the young will be exposed to more risks in the future, it is very important to form their ecological consciousness and pro-ecological behaviour. The aim of this paper was to identify the level of pro-ecological behaviour of students, as well as to determine whether there are differences between students of different level of education and gender. Applying five-degree scale of pro-ecological behaviour, 252 primary and secondary students from Belgrade were interviewed. Results of the research show that students behave inadequately in the surrounding in some situations (dealing with garbage, saving water and energy in the household and pro-ecological consumption). It has been shown that in the respect of proecological behaviour, there are no statistically significant differences between students of different level of education and gender. Given results can point at the directions of formal education in the respect of development of ecological consciousness and pro-ecological habits of the young in Serbia.
