Пољопривредна и животна средина - генеза и перспективна међусобних односа
No full textАнализирани су механизми утицаја пољопривреде на животну средину као једног од најзначајнијих реалних система интеракције друштва и природе. Пољопривреда је у фокусу због чињеница да је она најтрајнија, а по утицају на окружење, најприступнија област материјалне производње. Такође, пољопривреда је најзначајнији агенс деловања друштва на трансформацију и деградацију животне средине. Кумулативни ефекти утицаја пољопривреде на одрживи развој и одрживост екосфере су значајни. Целовито разумевање овог система је неопходно људском друштву јер је оно пољопривредом стекло услове за демографски раст, културни прогрес, сигурност, али и ефикасно средство за интензивирање деструкције планетарног система, животне средине и сопствену егзистенцијалну угроженост.Уредници: Радислав Вуловић, Данијела Пецарски, Драган Батавељи
Analiza prostornih planova jedinica lokalne samouprave u Republici Srpskoj sa posebnim osvrtom na zaštitu od požara
Get PDFProstorno planiranje ima veoma važnu ulogu kada je u pitanju prevencija, odnosno
ublažavanje posljedica od požara. Prostorni planovi jedinica lokalnih samouprava predstavljaju
adekvatan okvir za definisanje administrativnih, organizacionih, građevinskih, tehničkih i ekonomskih
mjera koje imaju za cilj da stanovništvo, materijalna dobra i životnu sredinu sačuvaju
od negativnih efekata požara i drugih elementarnih nepogoda. Aktuelni Zakon o uređenju prostora
i građenju, koji reguliše sve aspekte prostornog planiranja u Republici Srpskoj, prepoznaje
značaj integracije koncepta smanjenja rizika od elementarnih nepogoda i drugih nesreća u
sistem prostornog planiranja. Rješenja iz Zakona o zaštiti od požara, sa pratećim podzakonskim
aktima, sastavni su dio mjera vezanih za zaštitu od požara u prostornim planovima. U ovom
radu analizirano je 17 prostornih planova jedinica lokalnih samouprava u Republici Srpskoj sa
posebnim osvrtom na segment zaštite od požara.Urednici: Dejan Filipović, Velimir Šećerov, Dejan S. Đorđevi
Kartografska podrška održivom razvoju turizma
Get PDFRazvoj turizma i proučavanje prostora, u skladu sa konceptom održivog razvoja, zahteva odgovarajuću informacionu podršku. Karta je izvor geoinformacija i komunikacioni kanal prostorno organizovanih i grafički predstavljenih informacija. Kao sistematizovan skup informacija, određenog - konkretnog ili virtuelnog geografskog prostora, karta grafičkim izrazima daje prikaz: lokacije objekata, njihovih promena u prostoru i rezultata geoprostornih analiza i geoprocesiranja. Prostor je osnovni okvir turističkih kretanja, te se odgovornim upravljanjem stvara mogućnost pravilne valorizacije, promocije i prezentacije svih resursa koje taj prostor poseduje. Prostorno-vremenska i suštinska određenost turističkih vrednosti, kartografskom vizuelizacijom i uvođenjem inovativnih rešenja savremene digitalne tehnologije, pruža velike mogućnosti za komleksno, produktivno istraživanje turističkih vrednosti bilo kog područja. Interaktivne digitalne karte zasnovane na GIS tehnologiji, pored konvencionalnog načina prikaza mogu biti povezane i u kombinaciji sa satelitskim snimcima. Time se proširuje njihova referentna vrednost u obrazovnom, kognitivnom i istraživačkom smislu. U kombinaciji sa multimedijalnom tehnolоgijom, one postaju izvor širokog spektra informacija vezanih za određenu teritoriju. Osnov kartiranja turističkih vrednosti su topografski podaci, kako bi dobijene informacije bile tačne. Topografski sadržaj prvenstveno je odgovoran za pružanje informacija koje se koriste u orijentacione svrhe. Izbor topografske osnove, kao izvora za sastavljanje turističke karte, definiše adekvatan prikaz i dobijanje osnovnih i dopunskih informacija u procesu planiranja i korišćenje prostora kao osnovnog turističkog resursa. Kartografski prikazi potencijala i perspektive turističkog razvoja određenog područja zahtevaju vizuelizaciju geopodataka objedinjenih iz različitih izvora, formata, unakrsnih filtriranja, vremenskih perioda i načina dizajniranja. To zahteva standardizaciju pri kreiranju unificiranih modela referentnih informacija, funkcionalni kartografski dizajn i ergonomska rešenja pri izradi karata.Urednici: Dejan Filipović, Velimir Šećerov, Dejan S.

Geographical information systems and remote sensing methods in the estimation of potential dew volume and its utilization in the United Arab Emirates
Get PDFIn a fast growing region of Middle East and with rapid depletion of fossil groundwater, possibilities for dew utilization as a limited renewable water resource play an important role in the water management of the United Arab Emirates. Despite projected changes in air temperature and rainfall, geographical and topographical features of the UAE show some potential for dew harvesting, mostly at the altitudes higher than 1000 m and some isolated oasis areas. With the help of geographical information system (GIS), remote sensing, and numerical and theoretical methods, approximate volumes of dew were estimated. Meteorological data was inputted together with theoretical and numerical calculations into grids by using pixelization processes. Methods such as zonal statistics, kriging, semi-kriging, and interpolation were implemented through GIS software. Another method used in this research is supervised classification and normalized difference vegetation index (NDVI) which is being determined by means of software IDRISI terra set. After finishing all the proposed methods applied in this research, four belts of potential dew use were presented. The Arabian Desert in the territory of the United Arab Emirates has no potential for dew utilization. The zone close to the oases has very low possibility of dew use. The hilly-mountainous area between 500 and 800 m.a.s.l. has medium possibility for dew use. There is a high possibility for dew use on mountain Al Hajar, occupying the area higher than 800 m; 1.3% of the whole country’s territory has excellent potential for dew use. In this part of the country, theoretically, it is possible to use dew for farming and partial watering. Experimental study together with GIS, remote sensing, and numerical analysis may extend knowledge about dew properties. Although this research includes theoretical calculations of dew utilization and has some limitations, it still presents a new insight into climate cycles in this part of the Arabian Peninsula and a way to understand them better
Following the Balkan Migration Route: Informal Spatial Practices Created by “People on the Move”
Get PDFInformal migrations from the Middle East and North Africa to Europe since 2015 and their social, economic, and political implications have attracted the attention of the general public and policymakers, but have also been the focus of research in numerous social and urban studies.
As a region in the transitional phase, and officially in the process of EU accession, the Western
Balkan countries offer a special perspective. In that sense, Serbia, as well as Bosnia and
Herzegovina (BiH), play important roles as countries that border the EU, and therefore suitable
ground for the analysis of the practices of setting boundaries, actual state of porosity of
boundaries set, both symbolic and physically at the local and global level. An increasing number
of migrants has developed various informal spatial practices, as well as initiated changes in
public spaces. The new dynamics emphasize these spaces’ characteristics as those of public and
collective participation, as well as of potential conflicts, and permanent transformation processes.
On the one hand, massive migration flows have triggered increased nationalism, xenophobia,
and fear, but have also increased civic engagement and led to new solidarities, not only ‘from
above’, but also ‘from bellow’. This article examines public spaces beyond a neoliberal discourse
by highlighting their function as meeting points, offering possibilities for dialog between
‘privileged’ and ‘unprivileged’ population
Landscape Changes through History Following the Example of the Former Narrow-Gauge Railroad Belgrade (Cukarica-Obrenovac) Serbia
No full textThe process of urbanistic changes in space and time is not a steady one, nor always the same, followed by dissipation and demolition of objects, and the construction of new ones does not necessarily stabilize the process of changes within space. The changes that took place on the former narrow-gauge railroad Belgrade-Obrenovac reflect the changes in historical, cultural, and urban processes as well. The strategic plan of the development of the city and the villages altered, as certain sections of the railroad were being shut down. The observance of a particular infrastructure is, at the same time, the base for monitoring the urban changes through time. Forty years later, the railroad was not the only thing that had ceased to function. Using qualitative and historical methods, this study is an attempt to give answers to multiple questions, some of them being the reasons for the deconstruction of the railroad
Geographical index of concentration as an indicator of the spatial distribution of tourist attractions in Belgrade
Get PDFThe spatial structure of tourist attractions can be presented both qualitatively and quantitatively. One of the indicators of the spatial structure of tourism is the index of geographical concentration of tourist attractions. The geographical concentration of tourist attractions represents the ratio of the number of tourist attractions in the observed area and its structural parts and the total number of structural units of the analyzed area. This paper aims to determine the spatial distribution of attractions in the administrative territories of Belgrade municipalities and to establish correlations with tourist attendance. The number and spatial distribution of accommodation capacities are the largest in the central city municipalities so that the number of visitors is the largest in them. At the same time, the central city municipalities have the highest concentration of tourist attractions. For data collection, the authors used field research, OSM (Open Street Maps), Google maps, with software processing ArcGIS 10.2. The research results enabled the definition of the model of distribution of tourist attractions and indicated its application. This model of distribution of tourist attractions shows that they are mostly concentrated in the city center. This also means a small spatial connection of tourist attractions in the city center and peripheral parts

The aim of the study is to identity the reasons for rural abandonment in Serbia in order to define the optimal ways to overcome the current situation. An integrated questionnaire was designed for all respondents, and there were also several separate questionnaires. The results indicate the difficult situation in the rural area of Serbia and that the current trend of rural abandonment will continue
Geological Approach for Landfill Site Selection: A Case Study of Vršac Municipality, Serbia
Get PDFOne of the biggest problems of environmental protection in Serbia is landfills. It is often a case that the economic interests are predominant in the landfill sitting; thus, most landfills are not located according to standards. This study shows that detailed geological data assets combined with geographical modeling represents a reliable way to define and locate the landfill site. Geological evaluation is discussed in detail with regard to bedrock lithology, quaternary geology, geological structure, hydrogeology, surface runoff patterns, and topography. An approach combining geographical modeling and geology is presented for determining the sites suitable for landfill selection with respect to their geologic favorability. As opposed to numerous research papers on this topic, in the methodological procedure, special importance is devoted to the analysis of the geological criteria. In this way, it is significantly easier to determine the landfill area with the best characteristics due to geological structure and lithology which unequivocally and precisely indicates inadequate territories for candidate sites. The multicriteria decision analysis (MCDA) is based on geological criteria upgraded with road (primary, residential, secondary, and tertiary), settlements network, railway, airport, infrastructure, land use, hypsometry aquifer, wetland, and surface water. The score values are divided into four classes, i.e., restricted areas, suitable but avoid, suitable, and most suitable. Combining geographical modeling with geology led to the recognition of two locations to be most favorable for landfill site located in the most suitable area, which represents 25.3% of the study area
Impact of COVID-19 on Tourism in Serbia
No full textAt a time when tourism in Serbia represents a major segment of its economic development, COVID-19 has hit the tourism industry hard both locally and globally, and thus has affected the country’s economic condition and its development prospects. The government of the Republic of Serbia has taken a number of measures to combat the epidemic and to recover tourism. In order to assess whether these measures have been effective and to what extent they have contributed to the sustainability of tourism as an important economic contributor, field research was conducted on 110 owners of catering and tourist facilities in attractive tourist destinations in Serbia. Statistical analysis provided precise data on the decline in the number of tourists during the epidemic, as well as whether and to what extent these consequences were mitigated by a set of measures adopted by the government of the Republic of Serbia. It was concluded that, in the first five months of 2020, the influx of tourists decreased by almost 50% compared to the same period of the previous year (2019). According to the survey, the recovery of the tourism sector will take at least twelve months, so the measures that are being implemented must have long-term effects
