To examine potential relationships between meteorological variables and forest fires in Serbia, daily temperature, precipitation, relative humidity and wind speed data for 15 meteorological stations across Serbia were used to construct fire indices. The daily values of the Ångström and Nesterov indices were calculated for the period 2000-2017. A high number of forest fires occurred in 2007 and 2012 in Serbia, during a period of extremely high air temperatures in 2007, followed by the longest heat wave and the worst drought in 2012. In order to identify the ideal weather conditions for fire break outs, different combinations of input variables, e.g., meteorological variables (mean temperature, precipitation, relative humidity, maximum temperature, minimum temperature and wind speed), fire danger indices or a combination of both, for the Belgrade area during the period 1986-2017, were tested. It was found that using relative humidity or precipitation as a predictor only generates a satisfactory model for forecasting of number of forest fires.
A recent forest fire in the Republic of Serbia is discussed concerning classification, legislative framework and fire management, giving a detailed analysis of the forest fire occurrence. Analysing past and predicting future fires are crucial for policy development and forest management practices to prevent and mitigate fires. Fire hazard is discussed through several fire protection and prevention legislative documents. The nonparametric Mann-Kendall test was used to analyse resent forest fire data in an attempt to find causality in occurrences and frequency. The meteorological data and fire statistics provided by the Serbian Hydro-meteorological Service and the Ministry of Interior/Sector for Emergency Management of the Republic of Serbia were used to calculate the Forest Fire Weather Indices, along with deficit or surplus of precipitation for the case study of Tara Mountain. The paper highlights the need for better hierarchical classification of fire hazards and its harmonisation along with standardisations presented by leading international research institutions. A significant correlation between meteorological parameters and forest fire occurrence was found. This opens a possibility for further investigation and analysis of geophysical and anthropogenic driven factors that can influence disaster occurrence.

Miladin Nešić Kriminalističko-policijska akademija, Beograd olazište ovog rada jeste činjenica da performanse pojedinaca i organizacionih jedinica (organizacija) utiču na njihov učinak. Kada je reč o subjektima zaštite i spasavanja, njihovu ključnu organizacionu performansu predstavlja vreme odziva, shvaćeno kao trajanje od trenutka dolaska informacije o požaru do trenutka stizanja vatrogasno-spasilačke ekipe na mesto angažovanja. Preciznije, u radu se analizira uticaj vremena odziva vatrogasno-spasilačke jedinice na trajanje gašenja požara. Za analizu su korišćeni operativni podaci o požarima za područje grada Beograda, u periodu od 24 godine . Podaci su obrađeni primenom linearne regresije (Pearson Correlation) i njenom neparametarskom alternativom -Spirmanovim testom korelacije rangova (Spearman`s rank order correlation). Zaključeno je da vreme odziva vatrogasno-spasilačke jedinice na mesto požara (organizaciona performansa) utiče na trajanje njegovog gašenja, tako da, što je ono kraće -kraće je vreme gašenja požara, šteta je manja i ima više spasenih dobara (organizacioni učinak). Obrnuto, ako je vreme odziva vatrogasno-spasilačke jedinice duže -duže je i vreme gašenja požara, uz veće štete i manje spasenih dobara.Ključne reči: požar, vatrogasno-spasilačke ekipe, vreme odziva, intervencija, trajanje gašenja požara Uvod atrogasno-spasilački zadaci se u slučaju požara izvršavaju isključivo intervencijama na mestu požara. Pod pretpostavkom da vatrogasno-spasilačka jedinica dolaskom na mesto požara može samo da smanji njegovo trajanje, u radu je istraživan uticaj * Rad je rezultat istraživanja na projektu: "Upravljanje policijskom organizacijom u sprečavanju i suzbijanju pretnji bezbednosti u Republici Srbiji", koji finansira i realizuje Kriminalističko-policijska akademija u Beogradu, ciklus naučnih istraživanja 2015-2019. godina.
