The territory of the Republic of Serbia is vulnerable to various natural disasters, among which forest fires stand out. In relation with climate changes, the number of forest fires in Serbia has been increasing from year to year. Protected natural areas are especially endangered by wildfires. For Nature Park Golija, as the second largest in Serbia, with an area of 75,183 ha, and with MaB Reserve Golija-Studenica on part of its territory (53,804 ha), more attention should be paid in terms of forest fire mitigation. GIS and multi-criteria decision analysis are indispensable when it comes to spatial analysis for the purpose of natural disaster risk management. Index-based and fuzzy AHP methods were used, together with TOPSIS method for forest fire susceptibility zonation. Very high and high forest fire susceptibility zone were recorded on 26.85% (Forest Fire Susceptibility Index) and 25.75% (fuzzy AHP). The additional support for forest fire prevention is realized through an additional Internet of Thing (IoT)-based sensor network that enables the continuous collection of local meteorological and environmental data, which enables low-cost and reliable real-time fire risk assessment and detection and the improved long-term and short-term forest fire susceptibility assessment. Obtained results can be applied for adequate forest fire risk management, improvement of the monitoring, and early warning systems in the Republic of Serbia, but are also important for relevant authorities at national, regional, and local level, which will be able to coordinate and intervene in a case of emergency events.

Application of Weld Thermal Cycle Simulator in Manufacturing Engineering

As already known, no proper control or process control parameter which absolutely guarantees a high level quality of joints made by electro-resistive welding has been established so far, especially when all possible parameters are taken...

The Republic of Serbia has, in the previous period, actively worked on the development and adoption of a set of various public policy documents in order to build a more efficient system for responding to climate change, taking into account the challenges the country is facing. In previous years, we have witnessed significant consequences for the population, property and the environment caused by natural disasters, primarily floods, droughts and storms and consequently also fl ash floods and landslides. In order to define effective mitigation and adaptation measures to climate change, it was necessary to adopt a number of national-level documents, primarily a sectoral strategy for adapting to altered climate conditions, as well as to adopt or amend relevant legal regulations. This paper presents the results of work on this document and discusses the measures that need to be implemented in the coming period in order to mitigate the consequences of climate change and enable society to successfully adapt to the changed climate conditions.

The subject of the research paper is the improvement of the nature protection of the natural monument "Miljakovac Forest" and the natural monument "Kosutnjak Forest". The task is to analyze the management of these protected areas, with an emphasis on the activities undertaken for their protection and on anthropogenic activities that have a negative impact on natural values. The aim of the work is to investigate the effectiveness of the activities undertaken for nature protection in NM "Kosutnjak Forest" and NM "Miljakovačka šuma" and to propose new protection measures in locations where the protection actions undertaken did not yield results. The research includes the analysis of physical-geographic characteristics, the analysis of criteria important for determining the effectiveness of actions for nature protection and the proposal of measures for more effective environmental protection. The methods used are analysis and synthesis, AHP method (Analytic Hierarchy Process), comparative method, statistical and cartographic method. The criteria included in the analysis are distance from forest paths, distance from roads, anthropogenic impact on individual locations, distance from settlements. The criteria were ranked from 1 to 5 according to importance, based on which they were processed using the AHP method. Using Geographical Information Systems (GIS), that is, using the program QGIS 3.16. the research results are presented in the form of maps.
