Authors: Slobodan Gnjato, Tatjana Popov, Marko Ivanišević, Goran Trbić
Pages: 1 - 21
Abstract: The study analyzes trends in extreme climate indices in Sarajevo (Bosnia and Herzegovina). Based on daily maximum temperatures, daily minimum temperatures and daily precipitation during the 1961–2016 periods, a set of 27 indices recommended by the CCl/CLIVAR Expert Team for Climate Change Detection and Indices (ETCCDI) was calculated in the RClimDex (1.0) software. Given the results, the extreme temperature indices displayed a warming tendency throughout the year (most prominent in summer). The positive trends in warm temperature indices were stronger than the downward trends in cold ones. The highest trend values were estimated for TXx, TNx, TX90p, TN90p, WSDI, SU25 and SU30. The extreme precipitation indices displayed trends mixed in sign (annually and seasonally), but all statistically insignificant. However, upward trends in R99p, RX1day, RX5day, SDII, R10mm and R20mm suggest an increase in the magnitude and frequency of intense precipitation events. Moreover, significant changes in distribution of majority temperature indices were determined, whereas shifts in precipitation indices were mostly insignificant. The observed changes in extreme temperature indices are related with large-scale atmospheric circulation patterns (primarily the East-Atlantic pattern) and the Atlantic Multidecadal Oscillation. The negative correlation with the North Atlantic Oscillation, the East Atlantic/West Russia pattern and the Arctic Oscillation is found for majority of extreme precipitation indices.Key words: extreme temperatures and precipitation indices, trend, Generalized Extreme Value distribution, climate change, Sarajevo (Bosnia and Herzegovina)© 2021 Serbian Geographical Society, Belgrade, Serbia.This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Serbia

- Application of GIS in spatial analysis of industry concertation: The case
study of Tešanj municipality (Bosnia and Herzegovina)
Authors: Alma Kadušić, Sabahudin Smajić, Dragoslav Pavić, Vladimir Stojanović
Pages: 23 - 42
Abstract: The focus of this study is a spatial analysis of the industry distribution and concentration, on the example of municipality of Tešanj (Bosnia and Herzegovina), based on the application of GIS methods. Municipality of Tešanj is one of the most developed municipalities in Bosnia and Herzegovina, while Tešanj’s industry significantly contributes to the economic development of this country. GIS analysis of industry was based on the field work, locating and georeferencing industrial companies, acquisition, adaptation, adjustment and validation of digital surface models and google satellite imagery, mapping of relief, hydrography and transport network. With the aim of geovisualization of spatial distribution of industry, spatial descriptive statistics and non-parametric density estimation analysis (Kernel Density Estimation) were performed. In order to determine the distribution of industry in relation to relief (elevation, slope, and aspect), hydrography and transport network, GIS techniques of reclassification, vectorization, count point in polygons, buffer and clip geoprocessing tools were used. Conducted research provided a new insight into the data mining and visualization based on principles of QGIS, the effects of geographic factors on industry distribution, and confirmed the importance of relief, hydrographic and transport network on the concentration of industry in municipality Tešanj.Key words: GIS, spatial analysis, industry concentration, geographic factors, Tešanj© 2021 Serbian Geographical Society, Belgrade, Serbia.This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Serbia

- Demographic and economic aspects of urban shrinkage in Serbia - typology
and regional differentiation
Authors: Danica Djurkin, Marija Antić, Aljoša Budović
Pages: 43 - 78
Abstract: Urban shrinkage is a process that many European countries have been facing in recent decades. It had started in highly developed regions at the time of deindustrialisation, but since the 1990s, this process has also affected Central, Eastern and South-eastern Europe, with different patterns and dynamics of urban shrinkage. The political and economic crisis in Serbia during the 1990s, as well as the transition from a centrally governed and urban-based industrialisation to a neoliberal market economy, has brought significant changes in the development of cities, which faced declining demographic and economic vitality. This paper is focused on the analysis of the intensity and dynamics of demographic and economic aspects of urban shrinkage in Serbia and on classification of cities according to the different phases of urban shrinkage. Typological classification was performed using the K-means clustering algorithm. The cluster analysis is based on the use of relevant demographic and socio-economic indicators, for the period from 2002 to 2011. After identifying cities that recorded an increase in total population and relatively stable economic development, three types of shrinking cities were determined according to the intensity of demographic and economic shrinkage - cities with low, medium and high shrinkage intensity. The analysis of the main patterns and factors that influenced the different levels of urban shrinkage enabled a better understanding of this phenomenon in Serbia. The results indicate the heterogeneity of urban space due to different levels of demographic and economic shrinkage, thus it can serve as a starting point for future research of uneven urban development in Serbia.Key words: urban shrinkage, regional differentiation, typology, urban areas, Serbia© 2021 Serbian Geographical Society, Belgrade, Serbia.This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Serbia

- Investigating students attitudes and preferences towards disaster learning
multimedia to enhance prepardness
Authors: Ivanka Krnjić, Vladimir Cvetković
Pages: 79 - 96
Abstract: This paper presents quantitative research results regarding students’ attitudes and preferences towards disaster learning multimedia to enhance preparedness. The research was conducted during February and March 2021, where the respondents' answers were collected by sending an online survey questionnaire electronically to the email addresses of high schools. The general hypothesis refers to verifying the claim that the application of multimedia in children's education in schools about disasters ensures that students are acquainted with disasters and develop skills for safety and risk management in case of disasters. The regression model within the conducted research confirmed that the education of students through multimedia has the most significant impact on safety and risk management in disasters. Future directions of research in this field should move towards the analysis of different simulation models that can be of great help to acquaint students with the dangers arising from disasters. Given that simulation has proven to be an effective tool in acquiring knowledge, their application in educating students about disasters would inevitably have significant effects.Key words: disasters, preparedness, students, attitudes, e-learning, multimedia, Serbia© 2021 Serbian Geographical Society, Belgrade, Serbia.This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Serbia

- Perceptions of the problems of drinking water supply in Ziguinchor
(Senegal): Case of the peripheral district Nema 2
Authors: Cheikh Faye
Pages: 97 - 115
Abstract: Good water quality is important for the human health, energy and development. However, it is not available to millions of people throughout the world. In the Casamance region, the climatic situation has been characterised for the last thirty years by a drop in rainfall, combined with a demographic explosion which has led to an intensive exploitation of available water resources. Ziguinchor, the main city of Casamance, although located in a humid region rich in rainwater, does not guarantee continuous access to drinking water for all its inhabitants, especially those living in the outlying districts. The aim of this article is to show that the difficulties of access to drinking water in the outskirts of Ziguinchor are closely related to the inadequacy of the infrastructure for water supply. The methodology adopted revolves around three main axes: documentary research, data collection and data processing. The results of this study reveal that the water production capacity in Ziguinchor, of 9,500 m3 per day (i.e. 400 m3/h), in fact presents a production deficit in relation to demand from population estimated at 583,528 inhabitants, mainly noted in the peripheral zone such as Néma 2. The causes of this mismatch between supply and demand are due to inadequate infrastructure, but also to the pollution and salinity of water resources, in addition to poor governance of the supply sector. Faced with this situation, there is an imperative to mobilise water resources in the commune in a properly rational manner and to ensure more sustainable management.Key words: water resources, supply, drinking water, periphery, Ziguinchor© 2021 Serbian Geographical Society, Belgrade, Serbia.This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Serbia

- Urban development of Pyongiang under the influence of Juche idea
Authors: Zorica Pogrmić, Bojan Djerčan
Pages: 117 - 141
Abstract: In the Democratic People's Republic of Korea (DPRK), urban planning and urban architecture reflect the interest of the working class. The goal for the working class was to develop a specific type of urban planning, as a result of which the DPRK introduced a socialist model of urban planning. Until the beginning of 1970, the DPRK depended on the influence of the USSR, it wanted to go beyond that framework, especially in the field of urban planning and architecture. In the early 1970s, Kim Il-sung presented the thesis of Juche's idea, which encompasses all aspects of society. During the 1980s, Pyongyang was promoted to the world as the socialist capital of the world. However, in the 21st century, Korean architecture has noticed many changes compared to the past. In addition to remaining faithful to rationality and monumentality, social differences were given to special groups. Since the arrival and rise of Kim Jong-un to power, the newly built parts of Pyongyang are reminiscent of the physiognomy of capitalist cities.Key words: Pyongyang, Democratic People's Republic of Korea, Juche idea, urban planning, urban development© 2021 Serbian Geographical Society, Belgrade, Serbia.This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Serbia
