Evaluation of the urban regions of Serbia: Functional polycentricity
Get PDFThe subject of this paper is an evaluation of defined urban regions in Serbia, with an aim towards identifying their basic features, with special emphasis on the measurement of their functional polycentricity. These features include methods with following indicators: share of settled inhabitants to overall population number in the centre of urban region and surrounding area, according to the outcome; concentration level of employees in centres and structure of activities of active population performing an occupation, functional dependence of settlements in the area of the region and determining the functional polycentricity index of the urban region. Therefore, the goal of the paper is to clarify the difference between the urban regions that have developed in the area of Serbia, which are significant factors for further planning of polycentric and balanced regional development. The results of the survey show differences between urban regions. Almost half of the urban regions in Serbia have characteristics of monocentricity, while few polycentric urban regions differ in number of secondary centers. Certain differences between urban regions refer to the results related to share of the employees in primary centres in connection with the secondary centre region, if refers to a polycentric region, or in comparison to the region as a whole, if it implys to monocentric urban regions. All in all, primary differences between urban regions pertain to the degree of functional polycentrism
Tourism value assessment model of 'UNESCO-listed' monasteries: Kosovo and Metohija
No full textIn this study, a tourism value assessment of the monasteries in Kosovo and Metohija, which are inscribed on the UNESCO List of World Heritage in Danger. The applied model consists of two groups of indicators (resource values and state of development) and seven sub-indicators, which were ranked and evaluated by respondents on site. The aim of the study is to assess and highlight the tourist values and potentials that could contribute to marketing, point out the shortcomings and opportunities for further development and protection. The model was first applied for the valorization of the monastery, which due to the lack of legal protection, governance and political insecurity can become the subject of research performed by experts from various fields
Review of Biometeorology of Heatwaves and Warm Extremes in Europe
Get PDFNumerous extreme heatwaves producing large impacts on human health, agriculture, water resources, energy demand, regional economies, and forest ecosystems occurred during the first twenty years of the 21st century. The present study strives to provide a systematic review of recent studies of warm biometeorological extremes in Europe. The main aim of this paper is to provide a methodical summary of the observed changes in warm extremes, duration, and variability in different parts of Europe. During the last decade, much attention has been paid to the negative impacts of heat and humidity on human health. Therefore, the human biometeorology is required to appraise the human thermal environment in a way that human thermoregulation is taken into account. In many European countries and regions, future heat exposure will indeed exceed critical levels, and a steep increase in biometeorological heatwaves and warm extremes are expected. The indices that take into account human energy balance along with weather conditions should be used to examine the impacts of extreme heatwaves on human health and should be used as a basis for the determination of acclimatization to high-heat-stress conditions. A detailed description of recent studies that have used biometeorological indices such as Physiological Equivalent Temperature (PET) and Universal Thermal Climate Index (UTCI) for the estimation of warm extremes and their influence on human health is provided. Additionally, a short overview of the existence of the heat-health warning systems (HHWS), their conceptualization, and implementation across the European continent is considered, as well as the possibilities for further investigations and implementation of effective measures and programs that could reduce the adverse health impacts
Emigracioni potencijal mladih u Srbiji
Get PDFPromene obima, pravaca, regionalnih specifičnosti, kao i motiva za preseljavanje u Republici Srbiji su došle do punog izražaja na početku 21. veka. U uslovima negativnih demografskih trendova, emigracija mladog, reproduktivno i radno sposobnog stanovništva predstavlja jedno od vitalnih pitanja daljeg razvoja države. Imajući u vidu da je kategorija mladog stanovništva osnovni demografski resurs jednog društva, središnja tema ovog rada odnosi se na stavove, namere i motive mladih prema migracijama. U cilju prezentovanja regionalnih specifičnosti izuzetno heterogenog prostora Srbije, analiza je sprovedena u tri jedinice lokalne samouprave – Gradu Užicu, Gradu Leskovcu i Gradu Zaječaru, primenom fokusgrupnog istraživanja u populaciji učenika završne godine srednje škole (149 učenika podeljenih u 15 grupa). Dobijeni rezultati ukazuju na visok nivo spremnosti učenika da se po završetku školovanja isele iz Srbije. Kao dominantni push faktori izdvajaju se oni koji pripadaju ekonomskoj sferi – ostvareni prihodi, životni standard i mogućnosti za profesionalno napredovanje. U nedostatku pouzdanih statističkih i empirijskih podataka o preseljavanju stanovništva, prezentovani rezultati mogu predstavljati značajno polazište u kreiranju mera i aktivnosti populacione politike prema migracijama
Destinacijski imidž u omladinskom ekoturizmu Srbije
Get PDFAlmost half of domestic overnight stays in Serbia in 2019 were made in just five destinations, indicating the need for mitigation of such regional imbalances, particularly given the positive economic effects of domestic tourism. Large number of protected areas in Serbia provide opportunities for ecotourism development, which would make domestic tourist flows more disperse. Despite the important role of destination image in ecotourism development, previous studies of Serbian ecotourism did not focus on this construct. The aim of this study is to advance the knowledge about cognitive and affective image components of Serbian ecotourism destinations, including the role of socio-demographic characteristics and travelling behaviour on these representations. Youth, i.e., student population, represents the target group of the study. Five factors of the cognitive image were identified - General, Hospitality and Safety, Culture, Affordability and Nature. Hypotheses testing showed that cognitive perceptions varied in relation to the destination type and to some extent to previous visitation and gender, while affective responses varied in relation to gender and partially to the destination type and recent domestic travel experience. These findings provide theoretical contributions to ecotourism destination image research and practical implications for the destination managers and national policymakers.Gotovo polovina domaćih noćenja u Srbiji 2019. godine je ostvarena u svega pet destinacija, što ukazuje na potrebu za ublažavanjem regionalnih nejednakosti, posebno uzevši u obzir pozitivne ekonomske efekte domaćeg turizma. Veliki broj zaštićenih područja Srbije pruža prilike za razvoj ekoturizma, što bi domaće turističke tokove učinilo disperznijima. Uprkos važnoj ulozi destinacijskog imidža u razvoju ekoturizma, prethodne studije ekoturizma Srbije se nisu fokusirale na ovaj konstrukt. Cilj ove studije je unapređenje znanja o kognitivnim i afektivnim komponentama srpskih ekoturističkih destinacija, uključujući ulogu socio-demografskih odlika i turističkog ponašanja na ove predstave. Ciljnu grupu istraživanja predstavlja omladina, odnosno studentska populacija. Identifikovano je pet faktora kognitivnog imidža - opšti, ugostiteljstvo i bezbednost, kultura, priuštivost i priroda. Testiranje hipoteza je pokazalo da se kognitivne percepcije razlikuju u odnosu na destinacijski tip i u određenoj meri na prethodnu posećenost i pol, dok se afektivni odgovori razlikuju u odnosu na pol i delimično na destinacijski tip i skorije iskustvo u domaćem turizmu. Ovi rezultati pružaju teorijski doprinos istraživanju imidža ekoturističkih destinacija i praktične implikacije za upravljače destinacijama i državne kreatore politika
Changes in Soil Erosion Intensity Caused by Land Use and Demographic Changes in the Jablanica River Basin, Serbia
Get PDFThe aim of this research is to determine the change in the spatial distribution of erosion intensity in the territory of the Jablanica River Basin in the period 1971-2016 caused by land use and demographic changes. The Erosion Potential Method (EPM) was used to quantify changes in erosion intensity and to estimate the total annual sediment yield. The research results show that the value of the erosion coefficient decreased from 0.432 in 1971 to 0.360 in 2016. Specific annual gross erosion in the Jablanica River Basin was 654.41 m(3)/km(2)/year in 1971, while in 2016 it was 472.03 m(3)/km(2)/year. The analysis of proportional changes was used to determine demographic changes and land use patterns in the basin area. In terms of the scale and intensity of the erosion process, three types and one sub-type of population dynamics of settlements and land use changes were distinguished, respectively: progressive, stagnant, regressive and dominant regressive. It was concluded that the results show the significance of demographic and land use changes in the control of the intensity of erosion. The Soil Erosion Map may be useful to planners and land use managers to take appropriate decisions for soil conservation in the basin
Modelling and mapping of the COVID-19 trajectory and pandemic paths at global scale: A geographer's perspective
Get PDFIn December 2019, the virus SARS-CoV-2 responsible for the COVID-19 pandemic was detected in the Chinese city of Wuhan. The virus started to spread from China and dispersed over the rest of the world. In March 2020, WHO (World Health Organization) declared COVID-19 a pandemic. The transmission path of the pandemic was accelerated by different types of transportation. With complete analysis of spatial data, population density, types of traffic networks, and their properties, the spatial distribution of COVID-19 was estimated. GIS (Geographical Information System), numerical methods, and software for network analysis were used in this research to model scenarios of virus distribution on a global scale. The analyzed data included air, railway, marine, and road traffic. In the pandemic research, numerous models of possible trajectory of viruses can be created. Many have a stochastic character. This study includes all countries in the world affected by the COVID-19 up to date. In this study, GIS methods such as buffer, interpolations, and numerical analysis were used in order to estimate and visualize ongoing COVID-19 pandemic situation. According to the availability of new data, trajectory of virus paths was estimated. On the other hand, sparsely populated areas with poorly developed and small traffic networks (and isolated island territories) tend to be less or not affected as shown by the model. This low-cost approach can be used in order to define important measures that need to be addressed and implemented in order to successfully mitigate the implications of COVID-19 not only on global, but local and regional scales as well
On Regional Aspects of Vertical Distribution of Montenegrin Population
Get PDFThe coordinates of 18°26′ and 19°22′ east latitude and 41°52′ and 43°32′ north longitude set geographic position of Montenegro. The total length of its land borders is 614 km. The border alongside Croatia is 14 km long, alongside Bosnia and Herzegovina 225 km, alongside Serbia 20 km, and alongside Albania 172 km of the state border (partly across the Scadar lake and alongside the river Bojana). There is a 100 km of air distance between the furthest points at the sea. The factual length of the Montenegrin coast is about 280 km, which makes the serrated coefficient of 2.8. Montenegro is in proportion to its territory and population the smallest of all ex-Yugoslav republics. It spreads over the area of 13,812 square kilometres which makes 5.4% of ex-Yugoslav territory. According to 2003 census, 620.145 citizens lived in 1240 settlements, which were 45 citizens on a square kilometre. Out of 21 municipalities six are in the coastal region. The largest municipality in Montenegro (as well as in both ex-Yugoslavia and in the State union of Serbia and Montenegro) is Nikšić with 2,065 square kilometres, and the smallest is Tivat with 46 square kilometres. The capital of Montenegro is Podgorica with population of 96,076
New data on the stratigraphy of Badenian from Krčedin аrea (Northern Serbia, Central Paratethys)
Get PDFBadenian sediments are found for the first time in the surroundings of the Krčedin village. They represent remnants of the Central Paratethys marginal sea.
The sediments are represented by a basal conglomerate unit overlain by pure and
sandy marl. Foraminifera and rare ostracods are present, limited to the marls.
Normal gradation and the prevalence of planktonic foraminifera suggest a rapidly
deepening basin
Geografsko-ekološke karakteristike virusa Covid-19 u Srbiji
No full textVirus Covid-19 izazvao je velike promene u načinu života ljudi širom sveta. U slučaju epidemije i vanredne situacije na teritoriji jedne zemlje, veoma je značajno identifikovati potencijalna žarišta virusa i primeniti odgovarajuće mere u uklanjanju i ublažavanju istih. Upotrebom geografskih informacionih sistema (GIS) i dostupne baze podataka, moguće je pratiti prostorno i vremensko širenje virusa iz jedne lokalne samouprave u drugu, i tumačiti uzroke i posledice ove pojave i procesa. U ovom radu, pomoću GIS softverskih paketa i otvorenih podataka, analiziran je i kartografski prikazan broj zaraženih u Republici Srbiji po opštinama, u određenim kritičnim periodima, kao i broj novozaraženih u određenim vremenskim intervalima tokom trajanja vanrednog stanja
