The main goal of the research was to observe current state and explore possibilities for geotourism development in this area. By virtue of numerous indicators and sub-indicators, which are categorized either in group of Main or Additional values, this methodology gives us good insight in potentials of geoturism development. In addition, the methodology has been improved by involving tourists. This approach offers a more objective perspective of the needs of tourists and provides a starting point for further research. Recently, Serbia has been included in UNESCO's Global Geopark Network due to the Djerdap Gorge being made the country's first geopark. The Gradac Gorge is equally valuable; it has vast geoheritage, extraordinary landscapes, lush vegetation, and rich cultural and historical heritage. The geomorphological uniqueness of Gradac is the distinct meandering of the lower part of the river valley. Considering that it's also a protected area (a Landscape of Outstanding Features), a valuable fishing area, and one of the most important tourist sites in Valjevo Region, it has high potential to become one of Serbia's future Geoparks. The obtained results show the gorge having exceptional potential for geotourism development. On the other hand, it's necessary to improve the guide service, the visitor center, and more additional values.

Universal Thermal Climate Index, which represents the heat stress of the human organism caused by meteorological conditions, was used as an indicator of thermal comfort in the study. The main goal was to monitor changes in the index values, as well as the frequency of various categories of thermal stress during the hottest part of the year (months June, July, and August). For this research, mean daily meteorological data from the Meteorological Observatory Belgrade have been collected for the period from 1999 to 2018. The obtained results show a gradual change in the bioclimatic conditions, which are generally more adverse in July and August. Results also indicate that OTC in Belgrade was considerably reduced, especially in 2007, 2012, 2015, 2017, and 2018.

Special emphasis is placed on the bioclimatic index UTCI (Universal Thermal Climate Index), whose purpose is to evaluate the degree of thermal stress that the human body is exposed to. For this research, mean daily and hourly (07:00 and 14:00 CET) meteorological data from three weather stations (Zlatibor, Novi Sad and Niš) have been collected for the period from 1998 to 2017. In order to identify patterns of biothermal heat stress conditions, the thresholds of the daily UTCI (UTCI ≥38 ∘C, referred to as very strong heat stress, VSHS) at 14:00 CET are compared with the thresholds of daily maximum air temperature (tmax≥35 ∘C, referred to as hot days, HDs), which are further termed as heat wave events (HWEs). The findings show that the UTCI heat stress category “very strong heat stress“ at 14:00 CET indicates heat waves. The most extreme heat wave events occurred in 2007, 2012, 2015 and 2017. Moreover, three HWEs at Niš that occurred in July 2007 lasted 3, 10 and 4 d. HWEs and very strong heat stress events (VSHSEs) recorded in July 2007 (lasted 10 d each), 2012 (lasted 9 and 12 d) and 2015 (lasted 7 and 10 d) were of the longest duration and are considered to be the indicators of biothermal heat hazard. The daily UTCI14 h heat stress becomes more extreme in terms of severity and heat wave duration up to very strong heat stress.

The city is rich in natural resources and abundant in energy potential. The climatic and spatial characteristics favor the use of solar energy: the average annual solar radiation in Belgrade is 1446.8 kWh/m 2 /year, and the sunshine duration is around 2200 h/year. The analysis covered the area of 3240.7 km 2 (administrative area of Belgrade). Geospatial evaluation was based on three basic criteria: aspect, slope and land use. The Method of elimination in combination with modern methods in geospatial research (GIS) was applied. Based on the mentioned geospatial factors, thematic maps were made and later, their overlapping resulted in obtaining a synthesis Map of the suitability of the terrain for the construction of the PV plants. Of the total considered area, 13.68% were evaluated as suitable for the given purpose.

The purpose of this research is to observe the index change on a daily basis during the hottest part of the year (June, July, and August) over the period from 1998 to 2017. For the purposes of this analysis, hourly (7:00, 14:00), maximum and mean daily values of meteorological parameters (air temperature and relative humidity) were used, for the period of 20 years (1998-2017), which were measured at Niš weather station (43°19'N, 21°53'E, at an altitude of 202 meters). The findings indicate a gradual change in the bioclimatic characteristics of this area during this period, especially over the last decade. After 2007 there has been a decrease in the total number of days described as "comfortable". However, there has been an increase in the index values in all the other heat stress categories characterized by a higher or lower degree of thermal discomfort.The years 1998, 2000, 2003, 2007, 2011, 2016, 2015, and 2017 stand out as adverse years.

For this purposes Humidex, a simple heat index was applied. The research involved analyzing different Humidex values, the so-called "sub-indices" calculated based on hourly (7:00 and 14:00), mean daily and maximum values of meteorological parameters (air temperature and humidity) that were recorded at the meteorological station Belgrade-Vračar.), for the period 1999-2018. Outdoor thermal comfort in Belgrade is generally more adverse in July and August, resulting in most days belonging to the categories of "some discomfort" (30-39) and "great discomfort" (40-44), with periodic recording of the most severe categories of heat stress, as a category "very dangerous"(Humidex>55). Category of "very dangerous" heat stress shows linear increase during July, with positive trend of 0.03 days/10 years. The findings also show that from 1999 to 2018, mean index value gradually rose and values of sub-indices Humidex 14h and Humidex Tmax have exceeded thresholds 40 for great discomfort and 45 for dangerous heat stress more often then in the previous decades.

Laser Imaging Dетection And Ranging) могу да генеришу огромне количине 3D информација о карактеристикама сниманог простора. Поставља се питање: Шта све можемо урадити са тим подацима када их добијемо? Потенцијал LiDAR података да прикаже веродостојније, реалистичније визуализације снимљеног простора има изразито широку употребну вредност-може да утиче на више фаза у планском процесу. Овим радом покушаћемо да прикажемо и приближимо LiDAR технологију и партиципативно просторно планирање кроз коришћење 3D података у геовизуализацији са посебним акцентом на област јавног увида, с обзиром на подизање свести јавности о променама у урбанм и руралним подручјима. Последњих година, када говоримо о комуникативном планирању, увек се у центру пажње налази реалистична визуализација простора, односно 3D модели простора и широка палета апликација за манипулисање истим. Апликације за стварање виртуелне реалности који користе LiDAR податке имају могућност приказивања далеко више визуелних детаља и информација о простору него што је тренутно могуће са подацима добијеним из других извора и начина снимања терена. Способност да се информације о простору представе визуално и динамички, углавном кроз анимиране снимке тог предела, даје LiDAR технологији предност у односу на све друге методе и начине визуелизације простора, што је веома битно у циљу повећавања укључења и ангажовања јавности током читавог процеса планирања. 3D геовизуализација представља један веома реалан и природан пут преношења комплексних просторних информација ширим народним масама, а од посебне помоћи је људима који немају много искуства са читањем и интерпретацијом традиционалних 2D мапа које се данас у највише користе у планирању. Геовизуализација нам доноси један интерактиван приступ у размени и разумевању просторних информација између специјалиста и обичног човека. Док о овоме говоримо, апликације, као што су Noun 3D, Landscape Viewer и др., се развијају у циљу успостављања комуникације између просторних сценарија и шире јавности у партиципативном планском процесу.

Abstract: The data obtained by LiDAR technology (Laser Imaging Dеtection And Ranging) can generate large amount of 3D information about a scanned landscape. The question is: What can be done with that data once we gет it? The potentiал of LiDAR data to present more authentic and reаlistic visuаlization of given landscape has noticeably wide use vалue-it can affect more phases in the planning process. In our paper we will try to present and bring closer LiDAR technology and participatory spatiаl planning, through the use of 3D data in geovisuаlisation, with a speciаl stress on the area of public insight, considering the raising public awareness of changes in urban and rurаl areas. In recent years, when we tаlk about communicative planning, we have in mind more reаlistic visuаlization of space, in other words 3D spatiаl models and wide range of applications for managing those models. Virtuал reалity applications which use LiDAR data have possibilities of presenting far more visuаl dеtails and information about landscape than any other data obtained from other sources or by different way of scanning. Ability to present the landscape information in visuаl and dynamic ways, mostly through animated videos and images of the area, gives LiDAR technology the advantage over алl other mеthods and ways of spatiаl visuаlization, which is of great importance in order to include and engage public into the whole planning process. 3D geovisuаlization are seen as a more reаlistic and naturаl way of presenting complex spatiаl information to a wider public and it is particularly helpful to those who do not have a lot of experience in reading and interprетing 2D maps, which are mostly used in spatiал planning today. Geovisuаlization brings us an interactive access in the exchange of information bеtween an expert and a layman and the understanding of it. As we speak, applications, such as Noun 3D, Landscape Viewer еtc., are being developed in order to communicate spatiаl scenarios to a broad audience in the participatory planning process.

Njihove uloge i funkcije su raznolike, a značaj za očuvanje životne sredine neprocenjiv. Šumski ekositemi važan su deo ukupnog biodiverziteta, činioci su stabilnosti klimatskih elemenata, prirodni su filteri vazduha, imaju značajnu hidrološku ulogu, umanjuju intezitet erozije, preventivno utiču na pojavu klizišta, osnova su razvoja brojih privrednih grana sa posebnim akcentom na turizam, a takođe imaju izražen naučni i edukativni karakter. Pod uticajem čovekovih aktivnosti pritisak na šumska područja izuzetno je pojačan. U cilju sprečavanja dalje degradacije i uspostavljanja održivog načina korišćenja šumskog zemljišta, između ostalog, neophodna je adekvatna i pravovremena informaciona osnova. Radi dobijanja podataka visoke tačnosti, u veliкom broju ekološki razvijenih zemalja koristi se LiDAR tehnologija (Laser Imaging Detection And Ranging). Tehnologija pruža visinske podatke o topografiji terena i na osnovu tih podataka izrađuju se digitalni modeli terena (DMT) visoke preciznosti. Na osnovu LiDAR podataka i DTM-a mogu se vršiti različite analize praćenja stanja šumskog pokrivača, zoniranje koriščenja prostora, kreiranje simulacija kretanja mogućih požara, procene zahvaćenosti, ugroženosti i verovatnoće pojavljivanja istih, procene nastale štete i slično. Bitno je napomenuti da ova merenja pružaju važne informacije svim korisnicima prostora kojima je topografija bitan ulazni podatak – organi uprave, službe za zaštitu i spašavanje, privatni sektor i dr.
Abstract: Forests represent one of the most valuable natural resources of any country. Their roles and functions are various and their importance for preservation of environment is immeasurable. Forest ecosystems make an essential component of the overall biodiversity, they represent factors of climate stability, natural air filters, play a significant role in hydrology, reduce erosion intensity, help prevent landslides, create basis for development of many fields of economy, especially tourism, but also have a significant scientific and educational character. The pressure created by various human activities on forests is increasing. In order to prevent further degradation of forests and re-establish sustainable forestry it is necessary that we use adequate and up to date informational base. For obtaining high precision data a great number of ecologically developed countries apply LiDAR technology (Laser Imaging Detection And Ranging). This technology provides elevation information on the terrain topography and on the basis of the given data it generates high precision digital terrain models (DTMs). Based on LiDAR and DTM data different types of analysis can be made, such as forests monitoring, land use zoning, potential forest fire stimulations, estimation of fire size and its course, odds of occuring, damage evaluation, etc. It is important to mention that this technology provides highly useful information to all land users who consider topography as a significant data input – administrative authorities, rescue and protection services, private sector, and others.

Kako OIE predstavljaju neiscrpan prirodan vid energije koja se nalazi svuda oko nas, pretpostavlja se da će u budućnosti sve veći procenat ukupne proizvedene energije dolaziti upravo iz obnovljivih izvora. Radom je analizirana mogućnost korišćenja solarne energije i energije biomase, koje u ovoj oblasti pored energije vetra, imaju najveći potencijal na teritoriji Grada Vršca. Korišćenjem GIS softvera GeoMedia Professional 2016 (Hexagon Geospatial) i softvera Idrisi Selva, na osnovu definisanih kriterijuma, određene su najpovoljnije lokacije za postavljanje solarnih panela, kao i za uzgajanje brzorastuće biljke paulovnije koja se pokazala kao veoma dobar energent u mnogim zemljama sveta i Evrope, a u poslednje vreme dobija na važnosti i u Republici Srbiji. Dobijeni rezultati mogu biti značajni za unapređenje postojećeg nivoa korišćenja OIE u Gradu Vršcu koji je ocenjen kao nedovoljan, ali i u drugim delovima Republike Srbije, kao i u širem regionalnom okruženju.
Abstract: Renewable energy sources, sometimes understood as permanent energy sources, represent energy resources used for the production of electricity or heat, whose reserves are constantly or cyclically renewed. As the RES represent an inexhaustible natural form of energy that is all around us, it is assumed that in the future an increasing percentage of total energy produced will come from the renewable sources. The paper analyzes the possibility of using solar energy and biomass energy on the territory of the City of Vrsac, which, besides wind energy, have the highest potential in this area. Using the GIS software GeoMedia Professional 2016 (Hexagon Geospatial) and the Idrisi Selva software, based on defined criteria, the most favorable locations for the installation of solar panels have been determinated, as well as the cultivation locations for the fast-growing plant paulownia, which has proven to be a very good energy source in many countries of the world and Europe, and has recently gained importance in the Republic of Serbia. Having in mind that the level of use of the RES in the City of Vrsac is considered insufficient, the obtained results can be significant for improving the existing use of RES on this territory, but also in other parts of the Republic of Serbia and in a wider regional environment.

Proceniti kako i na koji način bioklimatski uslovi utiču na zdravstveno, odnosno psiho-fizičko stanje čoveka osnova je razvoja klimatoterapije, rekreacije i pojedinih oblika turizma. Jedan od najznačajnijih potencijala razvoja Grada Loznice i osnova razvoja turizma jeste zdravstveno-turističko-rekreativni centar Banja Koviljača, koja je proglašena banjom od perspektivnog međunarodnog značaja. Takođe, postoje i drugi, raznovrsni, ali nedovoljno iskorišćeni potencijali za unapređenje turizma i rekracije (planina Cer i manje poznata Banja Badanja). Cilj rada jeste afirmacija bioklimatskih analiza primenom modela Meneks u okviru geoekološkog vrednovanja predela, u domenu razvoja i unapređenja različitih vidova turizma i rekreacije koji se obavljaju na datom prostoru, kao i u oblasti medicinsko-geografskih istraživanja. Primenom ovog modela dobija se objektivna predstava i podaci o stvarnom bioklimatskom uticaju na teritoriji Loznice, koji se potom mogu iskoristiti u navedene svrhe. Za potrebe analize korišćeni su dnevni meteo-podaci iz 2016. godine uz pomoć kojih su određeni termofiziološki bioklimatski indeksi: Toplotno opterećenje u čoveku (HL) i Fiziološko naprezanje (PhS). U Srbiji i Republici Srpskoj postoji veliki broj banjskih i klimatskih mesta i rekreativnih zona, pa geoekološka evaluacija i bioklimatske analize tih područja savremenim metodama mogu umnogome doprineti efikasnijem sagledavanju potencijala njihovog budućeg razvoja, te većoj turističkoj afirmaciji.
The subjects of the research are the City of Loznica and the bioclimatic conditions prevailing in the given area. It is necessary to assess how and in which way bioclimatic conditions affect health or the psycho-physical state of a man in order to develop climatotherapy, recreation and certain forms of tourism. One of the most important potentials of the development of the City of Loznica and the basis of tourism development is the health-tourism-recreation center Banja Koviljaca, which has been proclaimed as a spa of perspective international significance. Also, there are other, varied, but insufficiently used potentials for the improvement of tourism and recreation (Cer mountain and lesser known Banja Badanja). The aim of the paper is the affirmation of the bioclimatic analysis using the Menex model within the geoecological evaluation of an area, in the domain of development and improvement of various forms of tourism and recreation that are performed in the given area, as well as in the field of medical-geographical researches. By applying this model we obtain an objective perception and data about the real bioclimatic impact on the territory of Loznica, which can then be used for the stated purposes. For the analysis needs the daily meteorological data from 2016 were used, by which thermophysiological bioclimatic indices Heat load (HL) and Physiological strain (PhS) have been determined. As there are many spa and climatic places and recreational zones in Serbia and the Republic of Srpska, the geoecological evaluation and bioclimatic analysis of these areas using the inovative methods can greatly contribute to a more effective understanding of the potentials of their future development, and to a greater touristic affirmation.

Prirodna bogatstva, izvori lekovitih, termomineralnih voda i povoljni bioklimatski uslovi osnova su razvoja zdravstveno-lečilišnog turizma Loznice. Cilj rada jeste primena metode Humideks za potrebe evaluacije bioklimatskih uslova koji vladaju na razmatranom prostoru tokom toplijeg dela godine, odnosno letnjih meseci jun, jul i avgust, kada je turistička posećenost Grada najveća. Bioklimatski indeks Humideks daje najbolje rezultate u oceni uticaja toplote, odnosno visoke temperature i vlažnosti vazduha na zdravstveno stanje ljudi. Za potrebe analize korišćene su terminske (07h, 14h), maksimalne i srednje dnevne vrednosti meteoroloških podataka za 2016. godinu koji su izmereni na meteorološkoj stanici Loznica (121 nmv.).
Abstract: The City of Loznica, along with Banja Koviljaca, Banja Badanja, the forest areas of the mountains Boranja, Gucevo, Cer and Iverk, which represent a special health and ecological value, are the most important elements of tourism development of the Macvanska district. Natural resources, sources of medicinal, thermo-mineral waters and favorable bioclimatic conditions are the basis of the development of spa and health tourism of Loznica. The aim of this paper is applying the Humidex method for the evaluation of the bioclimatic conditions which occur in the area under consideration during the warmer part of the year, ie the summer months of June, July and August, when the tourist visitation of city is highest. The bioclimatic index Humidex gives the best results in assessing the impact of heat, ie high temperature and humidity on the health of people. For the analysis needs, daily, maximum and hourly (07h, 14h) values of meteorological data for 2016 were used, which were measured at the weather station Loznica (121 m).

Neadekvatno deponovanje otpada jedna je od najznačanijih ljudskih aktivnosti koje negativno utiču na opšte stanje životne sredine seoskih naselja. Seoska naselja u najvećem broju slučajeva ne-maju adekvatno organizovan sistem sakupljanja otpada, što dovodi do formiranja brojnih divljih deponija. Seosko stanovništvo prosečno generiše 0,7 kg otpada/st./danu i veliki deo tog otpada završi na neuređenim odlagalištima. Neodrživo i nesavesno odlaganje otpada na divljim deponijama štetno utiče na zdravlje ljudi, zatim vodi ka zagađivanju vode, vazduha, a pre svega zemljišta. Zemljište je jedno od osnovnih elemenata životne sredine, u našoj zemlji okarakterisano je kao važan resurs i jedno od najznačajnijih prirodnih bogatstava kojima raspolažemo. Srbija je oduvek bila tradicionalno agrarna zemlja, a poljoprivreda je i danas najznačajnija privredna funkcija seoskih naselja. S obzirom da poljoprivredne površine zau-zimaju 67% ukupnih površina ruralnog prostora Srbije i da poljoprivreda i dalje predstavlja glavni izvor prihoda seoskih domaćinstava, postaje jasno zašto je zaštita i očuvanje zemljišta jedan od osnovnih prioriteta. Rešavanje problema slabije pokrivenosti organizovanim sakupljanjem otpada u ruralnim oblastima doprineće tom cilju i upravo iz tog razloga upravljanje otpadom zauzima značajno mesto u aktuelnoj praksi. Autori će u ovom radu analizirati postojeće stanje i probleme upravljanja otpadom koji se javljaju u okviru ruralnih područja Republike Srbije i ukazati na neke mogućnosti unapređenja sistema, kako bi se obezbedili bolji i kvalitetniji uslovi za život i rad ljudi.
Abstract: Rural areas in the Republic of Serbia are facing numerous problems, and problem of waste management is one of the biggest problems in the field of environment protection. Inadequate disposal of waste is one of the most important human activities that has a negative impact to the general conditions of environment in rural areas. In most cases villages don't have adequately organized system of collecting waste which leads to formation of numerous wild dumps. On average, rural population generates 0,7 kg/person/day and most of that waste ends up on non sanitary and illegal waste collection points. Unsustainable and unconscious disposal of waste on wild dumps has a harmful impact on human health, causes air and water pollution, but primarily pollution of soil. Soil is one of the main elements of the environment, and it is characterized in our country as an important resource and one of the most important nature resources we have at disposal. Serbia has a traditionally agrarian society, and agriculture is still the most important economic function of villages. Since 219

As Novi Sad is the administrative, cultural, educational, commercial, economic, health, social and historical center of Vojvodina it has a number of tourist potentials that are conducive to the development of various forms of tourism. The authors want to contribute with this paper to the affirmation of bioclimatic analysis and research using the Menex model in the field of geoecological evaluation of the urban landscape for the development and improvement of tourism and recreation as representative city functions. It is necessary to assess with what intensity and how bioclimatic conditions affect health or the psycho-physical state of a man in order to develop climatotherapy, recreation and certain forms of tourism. By applying the Menex model we can obtain an objective perception and data about real bioclimatic impact on the territory of Novi Sad and its surroundings. These can then be used for planning and management of urban areas and development of urban functions. During the research we used the daily meteorological data from 2015 by which thermo bioclimatic indices have been determined: Physiological Subjective Temperature (PST), Heat Load (HL) and Physiological Strain (PhS).

The main goal of the research was to observe current state and explore possibilities for geotourism development in this area. By virtue of numerous indicators and sub-indicators, which are categorized either in group of Main or Additional values, this methodology gives us good insight in potentials of geoturism development. In addition, the methodology has been improved by involving tourists. This approach offers a more objective perspective of the needs of tourists and provides a starting point for further research. Recently, Serbia has been included in UNESCO's Global Geopark Network due to the Djerdap Gorge being made the country's first geopark. The Gradac Gorge is equally valuable; it has vast geoheritage, extraordinary landscapes, lush vegetation, and rich cultural and historical heritage. The geomorphological uniqueness of Gradac is the distinct meandering of the lower part of the river valley. Considering that it's also a protected area (a Landscape of Outstanding Features), a valuable fishing area, and one of the most important tourist sites in Valjevo Region, it has high potential to become one of Serbia's future Geoparks. The obtained results show the gorge having exceptional potential for geotourism development. On the other hand, it's necessary to improve the guide service, the visitor center, and more additional values.

Universal Thermal Climate Index, which represents the heat stress of the human organism caused by meteorological conditions, was used as an indicator of thermal comfort in the study. The main goal was to monitor changes in the index values, as well as the frequency of various categories of thermal stress during the hottest part of the year (months June, July, and August). For this research, mean daily meteorological data from the Meteorological Observatory Belgrade have been collected for the period from 1999 to 2018. The obtained results show a gradual change in the bioclimatic conditions, which are generally more adverse in July and August. Results also indicate that OTC in Belgrade was considerably reduced, especially in 2007, 2012, 2015, 2017, and 2018.

Special emphasis is placed on the bioclimatic index UTCI (Universal Thermal Climate Index), whose purpose is to evaluate the degree of thermal stress that the human body is exposed to. For this research, mean daily and hourly (07:00 and 14:00 CET) meteorological data from three weather stations (Zlatibor, Novi Sad and Niš) have been collected for the period from 1998 to 2017. In order to identify patterns of biothermal heat stress conditions, the thresholds of the daily UTCI (UTCI ≥38 ∘C, referred to as very strong heat stress, VSHS) at 14:00 CET are compared with the thresholds of daily maximum air temperature (tmax≥35 ∘C, referred to as hot days, HDs), which are further termed as heat wave events (HWEs). The findings show that the UTCI heat stress category “very strong heat stress“ at 14:00 CET indicates heat waves. The most extreme heat wave events occurred in 2007, 2012, 2015 and 2017. Moreover, three HWEs at Niš that occurred in July 2007 lasted 3, 10 and 4 d. HWEs and very strong heat stress events (VSHSEs) recorded in July 2007 (lasted 10 d each), 2012 (lasted 9 and 12 d) and 2015 (lasted 7 and 10 d) were of the longest duration and are considered to be the indicators of biothermal heat hazard. The daily UTCI14 h heat stress becomes more extreme in terms of severity and heat wave duration up to very strong heat stress.

The city is rich in natural resources and abundant in energy potential. The climatic and spatial characteristics favor the use of solar energy: the average annual solar radiation in Belgrade is 1446.8 kWh/m 2 /year, and the sunshine duration is around 2200 h/year. The analysis covered the area of 3240.7 km 2 (administrative area of Belgrade). Geospatial evaluation was based on three basic criteria: aspect, slope and land use. The Method of elimination in combination with modern methods in geospatial research (GIS) was applied. Based on the mentioned geospatial factors, thematic maps were made and later, their overlapping resulted in obtaining a synthesis Map of the suitability of the terrain for the construction of the PV plants. Of the total considered area, 13.68% were evaluated as suitable for the given purpose.

The purpose of this research is to observe the index change on a daily basis during the hottest part of the year (June, July, and August) over the period from 1998 to 2017. For the purposes of this analysis, hourly (7:00, 14:00), maximum and mean daily values of meteorological parameters (air temperature and relative humidity) were used, for the period of 20 years (1998-2017), which were measured at Niš weather station (43°19'N, 21°53'E, at an altitude of 202 meters). The findings indicate a gradual change in the bioclimatic characteristics of this area during this period, especially over the last decade. After 2007 there has been a decrease in the total number of days described as "comfortable". However, there has been an increase in the index values in all the other heat stress categories characterized by a higher or lower degree of thermal discomfort.The years 1998, 2000, 2003, 2007, 2011, 2016, 2015, and 2017 stand out as adverse years.

For this purposes Humidex, a simple heat index was applied. The research involved analyzing different Humidex values, the so-called "sub-indices" calculated based on hourly (7:00 and 14:00), mean daily and maximum values of meteorological parameters (air temperature and humidity) that were recorded at the meteorological station Belgrade-Vračar.), for the period 1999-2018. Outdoor thermal comfort in Belgrade is generally more adverse in July and August, resulting in most days belonging to the categories of "some discomfort" (30-39) and "great discomfort" (40-44), with periodic recording of the most severe categories of heat stress, as a category "very dangerous"(Humidex>55). Category of "very dangerous" heat stress shows linear increase during July, with positive trend of 0.03 days/10 years. The findings also show that from 1999 to 2018, mean index value gradually rose and values of sub-indices Humidex 14h and Humidex Tmax have exceeded thresholds 40 for great discomfort and 45 for dangerous heat stress more often then in the previous decades.

Laser Imaging Dетection And Ranging) могу да генеришу огромне количине 3D информација о карактеристикама сниманог простора. Поставља се питање: Шта све можемо урадити са тим подацима када их добијемо? Потенцијал LiDAR података да прикаже веродостојније, реалистичније визуализације снимљеног простора има изразито широку употребну вредност-може да утиче на више фаза у планском процесу. Овим радом покушаћемо да прикажемо и приближимо LiDAR технологију и партиципативно просторно планирање кроз коришћење 3D података у геовизуализацији са посебним акцентом на област јавног увида, с обзиром на подизање свести јавности о променама у урбанм и руралним подручјима. Последњих година, када говоримо о комуникативном планирању, увек се у центру пажње налази реалистична визуализација простора, односно 3D модели простора и широка палета апликација за манипулисање истим. Апликације за стварање виртуелне реалности који користе LiDAR податке имају могућност приказивања далеко више визуелних детаља и информација о простору него што је тренутно могуће са подацима добијеним из других извора и начина снимања терена. Способност да се информације о простору представе визуално и динамички, углавном кроз анимиране снимке тог предела, даје LiDAR технологији предност у односу на све друге методе и начине визуелизације простора, што је веома битно у циљу повећавања укључења и ангажовања јавности током читавог процеса планирања. 3D геовизуализација представља један веома реалан и природан пут преношења комплексних просторних информација ширим народним масама, а од посебне помоћи је људима који немају много искуства са читањем и интерпретацијом традиционалних 2D мапа које се данас у највише користе у планирању. Геовизуализација нам доноси један интерактиван приступ у размени и разумевању просторних информација између специјалиста и обичног човека. Док о овоме говоримо, апликације, као што су Noun 3D, Landscape Viewer и др., се развијају у циљу успостављања комуникације између просторних сценарија и шире јавности у партиципативном планском процесу.

Abstract: The data obtained by LiDAR technology (Laser Imaging Dеtection And Ranging) can generate large amount of 3D information about a scanned landscape. The question is: What can be done with that data once we gет it? The potentiал of LiDAR data to present more authentic and reаlistic visuаlization of given landscape has noticeably wide use vалue-it can affect more phases in the planning process. In our paper we will try to present and bring closer LiDAR technology and participatory spatiаl planning, through the use of 3D data in geovisuаlisation, with a speciаl stress on the area of public insight, considering the raising public awareness of changes in urban and rurаl areas. In recent years, when we tаlk about communicative planning, we have in mind more reаlistic visuаlization of space, in other words 3D spatiаl models and wide range of applications for managing those models. Virtuал reалity applications which use LiDAR data have possibilities of presenting far more visuаl dеtails and information about landscape than any other data obtained from other sources or by different way of scanning. Ability to present the landscape information in visuаl and dynamic ways, mostly through animated videos and images of the area, gives LiDAR technology the advantage over алl other mеthods and ways of spatiаl visuаlization, which is of great importance in order to include and engage public into the whole planning process. 3D geovisuаlization are seen as a more reаlistic and naturаl way of presenting complex spatiаl information to a wider public and it is particularly helpful to those who do not have a lot of experience in reading and interprетing 2D maps, which are mostly used in spatiал planning today. Geovisuаlization brings us an interactive access in the exchange of information bеtween an expert and a layman and the understanding of it. As we speak, applications, such as Noun 3D, Landscape Viewer еtc., are being developed in order to communicate spatiаl scenarios to a broad audience in the participatory planning process.

Njihove uloge i funkcije su raznolike, a značaj za očuvanje životne sredine neprocenjiv. Šumski ekositemi važan su deo ukupnog biodiverziteta, činioci su stabilnosti klimatskih elemenata, prirodni su filteri vazduha, imaju značajnu hidrološku ulogu, umanjuju intezitet erozije, preventivno utiču na pojavu klizišta, osnova su razvoja brojih privrednih grana sa posebnim akcentom na turizam, a takođe imaju izražen naučni i edukativni karakter. Pod uticajem čovekovih aktivnosti pritisak na šumska područja izuzetno je pojačan. U cilju sprečavanja dalje degradacije i uspostavljanja održivog načina korišćenja šumskog zemljišta, između ostalog, neophodna je adekvatna i pravovremena informaciona osnova. Radi dobijanja podataka visoke tačnosti, u veliкom broju ekološki razvijenih zemalja koristi se LiDAR tehnologija (Laser Imaging Detection And Ranging). Tehnologija pruža visinske podatke o topografiji terena i na osnovu tih podataka izrađuju se digitalni modeli terena (DMT) visoke preciznosti. Na osnovu LiDAR podataka i DTM-a mogu se vršiti različite analize praćenja stanja šumskog pokrivača, zoniranje koriščenja prostora, kreiranje simulacija kretanja mogućih požara, procene zahvaćenosti, ugroženosti i verovatnoće pojavljivanja istih, procene nastale štete i slično. Bitno je napomenuti da ova merenja pružaju važne informacije svim korisnicima prostora kojima je topografija bitan ulazni podatak – organi uprave, službe za zaštitu i spašavanje, privatni sektor i dr.
Abstract: Forests represent one of the most valuable natural resources of any country. Their roles and functions are various and their importance for preservation of environment is immeasurable. Forest ecosystems make an essential component of the overall biodiversity, they represent factors of climate stability, natural air filters, play a significant role in hydrology, reduce erosion intensity, help prevent landslides, create basis for development of many fields of economy, especially tourism, but also have a significant scientific and educational character. The pressure created by various human activities on forests is increasing. In order to prevent further degradation of forests and re-establish sustainable forestry it is necessary that we use adequate and up to date informational base. For obtaining high precision data a great number of ecologically developed countries apply LiDAR technology (Laser Imaging Detection And Ranging). This technology provides elevation information on the terrain topography and on the basis of the given data it generates high precision digital terrain models (DTMs). Based on LiDAR and DTM data different types of analysis can be made, such as forests monitoring, land use zoning, potential forest fire stimulations, estimation of fire size and its course, odds of occuring, damage evaluation, etc. It is important to mention that this technology provides highly useful information to all land users who consider topography as a significant data input – administrative authorities, rescue and protection services, private sector, and others.

Kako OIE predstavljaju neiscrpan prirodan vid energije koja se nalazi svuda oko nas, pretpostavlja se da će u budućnosti sve veći procenat ukupne proizvedene energije dolaziti upravo iz obnovljivih izvora. Radom je analizirana mogućnost korišćenja solarne energije i energije biomase, koje u ovoj oblasti pored energije vetra, imaju najveći potencijal na teritoriji Grada Vršca. Korišćenjem GIS softvera GeoMedia Professional 2016 (Hexagon Geospatial) i softvera Idrisi Selva, na osnovu definisanih kriterijuma, određene su najpovoljnije lokacije za postavljanje solarnih panela, kao i za uzgajanje brzorastuće biljke paulovnije koja se pokazala kao veoma dobar energent u mnogim zemljama sveta i Evrope, a u poslednje vreme dobija na važnosti i u Republici Srbiji. Dobijeni rezultati mogu biti značajni za unapređenje postojećeg nivoa korišćenja OIE u Gradu Vršcu koji je ocenjen kao nedovoljan, ali i u drugim delovima Republike Srbije, kao i u širem regionalnom okruženju.
Abstract: Renewable energy sources, sometimes understood as permanent energy sources, represent energy resources used for the production of electricity or heat, whose reserves are constantly or cyclically renewed. As the RES represent an inexhaustible natural form of energy that is all around us, it is assumed that in the future an increasing percentage of total energy produced will come from the renewable sources. The paper analyzes the possibility of using solar energy and biomass energy on the territory of the City of Vrsac, which, besides wind energy, have the highest potential in this area. Using the GIS software GeoMedia Professional 2016 (Hexagon Geospatial) and the Idrisi Selva software, based on defined criteria, the most favorable locations for the installation of solar panels have been determinated, as well as the cultivation locations for the fast-growing plant paulownia, which has proven to be a very good energy source in many countries of the world and Europe, and has recently gained importance in the Republic of Serbia. Having in mind that the level of use of the RES in the City of Vrsac is considered insufficient, the obtained results can be significant for improving the existing use of RES on this territory, but also in other parts of the Republic of Serbia and in a wider regional environment.

Proceniti kako i na koji način bioklimatski uslovi utiču na zdravstveno, odnosno psiho-fizičko stanje čoveka osnova je razvoja klimatoterapije, rekreacije i pojedinih oblika turizma. Jedan od najznačajnijih potencijala razvoja Grada Loznice i osnova razvoja turizma jeste zdravstveno-turističko-rekreativni centar Banja Koviljača, koja je proglašena banjom od perspektivnog međunarodnog značaja. Takođe, postoje i drugi, raznovrsni, ali nedovoljno iskorišćeni potencijali za unapređenje turizma i rekracije (planina Cer i manje poznata Banja Badanja). Cilj rada jeste afirmacija bioklimatskih analiza primenom modela Meneks u okviru geoekološkog vrednovanja predela, u domenu razvoja i unapređenja različitih vidova turizma i rekreacije koji se obavljaju na datom prostoru, kao i u oblasti medicinsko-geografskih istraživanja. Primenom ovog modela dobija se objektivna predstava i podaci o stvarnom bioklimatskom uticaju na teritoriji Loznice, koji se potom mogu iskoristiti u navedene svrhe. Za potrebe analize korišćeni su dnevni meteo-podaci iz 2016. godine uz pomoć kojih su određeni termofiziološki bioklimatski indeksi: Toplotno opterećenje u čoveku (HL) i Fiziološko naprezanje (PhS). U Srbiji i Republici Srpskoj postoji veliki broj banjskih i klimatskih mesta i rekreativnih zona, pa geoekološka evaluacija i bioklimatske analize tih područja savremenim metodama mogu umnogome doprineti efikasnijem sagledavanju potencijala njihovog budućeg razvoja, te većoj turističkoj afirmaciji.
The subjects of the research are the City of Loznica and the bioclimatic conditions prevailing in the given area. It is necessary to assess how and in which way bioclimatic conditions affect health or the psycho-physical state of a man in order to develop climatotherapy, recreation and certain forms of tourism. One of the most important potentials of the development of the City of Loznica and the basis of tourism development is the health-tourism-recreation center Banja Koviljaca, which has been proclaimed as a spa of perspective international significance. Also, there are other, varied, but insufficiently used potentials for the improvement of tourism and recreation (Cer mountain and lesser known Banja Badanja). The aim of the paper is the affirmation of the bioclimatic analysis using the Menex model within the geoecological evaluation of an area, in the domain of development and improvement of various forms of tourism and recreation that are performed in the given area, as well as in the field of medical-geographical researches. By applying this model we obtain an objective perception and data about the real bioclimatic impact on the territory of Loznica, which can then be used for the stated purposes. For the analysis needs the daily meteorological data from 2016 were used, by which thermophysiological bioclimatic indices Heat load (HL) and Physiological strain (PhS) have been determined. As there are many spa and climatic places and recreational zones in Serbia and the Republic of Srpska, the geoecological evaluation and bioclimatic analysis of these areas using the inovative methods can greatly contribute to a more effective understanding of the potentials of their future development, and to a greater touristic affirmation.

Prirodna bogatstva, izvori lekovitih, termomineralnih voda i povoljni bioklimatski uslovi osnova su razvoja zdravstveno-lečilišnog turizma Loznice. Cilj rada jeste primena metode Humideks za potrebe evaluacije bioklimatskih uslova koji vladaju na razmatranom prostoru tokom toplijeg dela godine, odnosno letnjih meseci jun, jul i avgust, kada je turistička posećenost Grada najveća. Bioklimatski indeks Humideks daje najbolje rezultate u oceni uticaja toplote, odnosno visoke temperature i vlažnosti vazduha na zdravstveno stanje ljudi. Za potrebe analize korišćene su terminske (07h, 14h), maksimalne i srednje dnevne vrednosti meteoroloških podataka za 2016. godinu koji su izmereni na meteorološkoj stanici Loznica (121 nmv.).
Abstract: The City of Loznica, along with Banja Koviljaca, Banja Badanja, the forest areas of the mountains Boranja, Gucevo, Cer and Iverk, which represent a special health and ecological value, are the most important elements of tourism development of the Macvanska district. Natural resources, sources of medicinal, thermo-mineral waters and favorable bioclimatic conditions are the basis of the development of spa and health tourism of Loznica. The aim of this paper is applying the Humidex method for the evaluation of the bioclimatic conditions which occur in the area under consideration during the warmer part of the year, ie the summer months of June, July and August, when the tourist visitation of city is highest. The bioclimatic index Humidex gives the best results in assessing the impact of heat, ie high temperature and humidity on the health of people. For the analysis needs, daily, maximum and hourly (07h, 14h) values of meteorological data for 2016 were used, which were measured at the weather station Loznica (121 m).

Neadekvatno deponovanje otpada jedna je od najznačanijih ljudskih aktivnosti koje negativno utiču na opšte stanje životne sredine seoskih naselja. Seoska naselja u najvećem broju slučajeva ne-maju adekvatno organizovan sistem sakupljanja otpada, što dovodi do formiranja brojnih divljih deponija. Seosko stanovništvo prosečno generiše 0,7 kg otpada/st./danu i veliki deo tog otpada završi na neuređenim odlagalištima. Neodrživo i nesavesno odlaganje otpada na divljim deponijama štetno utiče na zdravlje ljudi, zatim vodi ka zagađivanju vode, vazduha, a pre svega zemljišta. Zemljište je jedno od osnovnih elemenata životne sredine, u našoj zemlji okarakterisano je kao važan resurs i jedno od najznačajnijih prirodnih bogatstava kojima raspolažemo. Srbija je oduvek bila tradicionalno agrarna zemlja, a poljoprivreda je i danas najznačajnija privredna funkcija seoskih naselja. S obzirom da poljoprivredne površine zau-zimaju 67% ukupnih površina ruralnog prostora Srbije i da poljoprivreda i dalje predstavlja glavni izvor prihoda seoskih domaćinstava, postaje jasno zašto je zaštita i očuvanje zemljišta jedan od osnovnih prioriteta. Rešavanje problema slabije pokrivenosti organizovanim sakupljanjem otpada u ruralnim oblastima doprineće tom cilju i upravo iz tog razloga upravljanje otpadom zauzima značajno mesto u aktuelnoj praksi. Autori će u ovom radu analizirati postojeće stanje i probleme upravljanja otpadom koji se javljaju u okviru ruralnih područja Republike Srbije i ukazati na neke mogućnosti unapređenja sistema, kako bi se obezbedili bolji i kvalitetniji uslovi za život i rad ljudi.
Abstract: Rural areas in the Republic of Serbia are facing numerous problems, and problem of waste management is one of the biggest problems in the field of environment protection. Inadequate disposal of waste is one of the most important human activities that has a negative impact to the general conditions of environment in rural areas. In most cases villages don't have adequately organized system of collecting waste which leads to formation of numerous wild dumps. On average, rural population generates 0,7 kg/person/day and most of that waste ends up on non sanitary and illegal waste collection points. Unsustainable and unconscious disposal of waste on wild dumps has a harmful impact on human health, causes air and water pollution, but primarily pollution of soil. Soil is one of the main elements of the environment, and it is characterized in our country as an important resource and one of the most important nature resources we have at disposal. Serbia has a traditionally agrarian society, and agriculture is still the most important economic function of villages. Since 219

As Novi Sad is the administrative, cultural, educational, commercial, economic, health, social and historical center of Vojvodina it has a number of tourist potentials that are conducive to the development of various forms of tourism. The authors want to contribute with this paper to the affirmation of bioclimatic analysis and research using the Menex model in the field of geoecological evaluation of the urban landscape for the development and improvement of tourism and recreation as representative city functions. It is necessary to assess with what intensity and how bioclimatic conditions affect health or the psycho-physical state of a man in order to develop climatotherapy, recreation and certain forms of tourism. By applying the Menex model we can obtain an objective perception and data about real bioclimatic impact on the territory of Novi Sad and its surroundings. These can then be used for planning and management of urban areas and development of urban functions. During the research we used the daily meteorological data from 2015 by which thermo bioclimatic indices have been determined: Physiological Subjective Temperature (PST), Heat Load (HL) and Physiological Strain (PhS).

Abstract: In this paper, the bioclimatic analysis of the Nature Park "Zlatibor" was conducted, by using the Universal Thermal Climate Index (UTCI), which represents the heat stress of the human organism caused by meteorological conditions. The aim of the research is to monitor the annual course and changes in the values of the index, as well as the representation of the frequency of various categories of thermal stress at the seasonal level, in the period 2012-2017. For the analysis needs, daily values of meteorological data (air temperature, air pressure, relative humidity, wind speed and total cloud cover) for period of 6 years (2012-2017) were used, which were measured at the main weather station Zlatibor (1028 m). The obtained results shows a gradual change of the seasonal bioclimatic characteristics of this area. The most significant changes were recorded during the summer and early autumn, which is in line with the previous research on weather and bioclimatic conditions of the territory of the Republic of Serbia, which indicated the existence of a positive trend in the increase in average annual temperatures.

Abstract: The data obtained by LiDAR technology (Laser Imaging Dеtection And Ranging) can generate large amount of 3D information about a scanned landscape. The question is: What can be done with that data once we gет it? The potentiал of LiDAR data to present more authentic and reаlistic visuаlization of given landscape has noticeably wide use vалue-it can affect more phases in the planning process. In our paper we will try to present and bring closer LiDAR technology and participatory spatiаl planning, through the use of 3D data in geovisuаlisation, with a speciаl stress on the area of public insight, considering the raising public awareness of changes in urban and rurаl areas. In recent years, when we tаlk about communicative planning, we have in mind more reаlistic visuаlization of space, in other words 3D spatiаl models and wide range of applications for managing those models. Virtuал reалity applications which use LiDAR data have possibilities of presenting far more visuаl dеtails and information about landscape than any other data obtained from other sources or by different way of scanning. Ability to present the landscape information in visuаl and dynamic ways, mostly through animated videos and images of the area, gives LiDAR technology the advantage over алl other mеthods and ways of spatiаl visuаlization, which is of great importance in order to include and engage public into the whole planning process. 3D geovisuаlization are seen as a more reаlistic and naturаl way of presenting complex spatiаl information to a wider public and it is particularly helpful to those who do not have a lot of experience in reading and interprетing 2D maps, which are mostly used in spatiал planning today. Geovisuаlization brings us an interactive access in the exchange of information bеtween an expert and a layman and the understanding of it. As we speak, applications, such as Noun 3D, Landscape Viewer еtc., are being developed in order to communicate spatiаl scenarios to a broad audience in the participatory planning process.
Abstract: Forests represent one of the most valuable natural resources of any country. Their roles and functions are various and their importance for preservation of environment is immeasurable. Forest ecosystems make an essential component of the overall biodiversity, they represent factors of climate stability, natural air filters, play a significant role in hydrology, reduce erosion intensity, help prevent landslides, create basis for development of many fields of economy, especially tourism, but also have a significant scientific and educational character. The pressure created by various human activities on forests is increasing. In order to prevent further degradation of forests and re-establish sustainable forestry it is necessary that we use adequate and up to date informational base. For obtaining high precision data a great number of ecologically developed countries apply LiDAR technology (Laser Imaging Detection And Ranging). This technology provides elevation information on the terrain topography and on the basis of the given data it generates high precision digital terrain models (DTMs). Based on LiDAR and DTM data different types of analysis can be made, such as forests monitoring, land use zoning, potential forest fire stimulations, estimation of fire size and its course, odds of occuring, damage evaluation, etc. It is important to mention that this technology provides highly useful information to all land users who consider topography as a significant data input – administrative authorities, rescue and protection services, private sector, and others.
Abstract: Renewable energy sources, sometimes understood as permanent energy sources, represent energy resources used for the production of electricity or heat, whose reserves are constantly or cyclically renewed. As the RES represent an inexhaustible natural form of energy that is all around us, it is assumed that in the future an increasing percentage of total energy produced will come from the renewable sources. The paper analyzes the possibility of using solar energy and biomass energy on the territory of the City of Vrsac, which, besides wind energy, have the highest potential in this area. Using the GIS software GeoMedia Professional 2016 (Hexagon Geospatial) and the Idrisi Selva software, based on defined criteria, the most favorable locations for the installation of solar panels have been determinated, as well as the cultivation locations for the fast-growing plant paulownia, which has proven to be a very good energy source in many countries of the world and Europe, and has recently gained importance in the Republic of Serbia. Having in mind that the level of use of the RES in the City of Vrsac is considered insufficient, the obtained results can be significant for improving the existing use of RES on this territory, but also in other parts of the Republic of Serbia and in a wider regional environment.
