Systems for sustainability assessment of buildings and surroundings (LEED, BREEAM, CASBEE, DGNB, Green Star) in more or less direct way, takes into account factors of interaction between buildings and neighborhoods. System which most directly shows the correlation between the achieved quality and conditionality between buildings and surroundings is the system developed in Japan, the CASBEE system. The measure of sustainability in this system is expressed in Building Environmental Efficiency (BEE) as an indicator which is based on the results of separate scores obtained for quality and load reduction.

The expected impact of climate change on forests in Serbia is already recorded in the studies of oak. This research was focused on the study of the impact of 15 climate variables from CARPATCLIM database over the Turkey oak from stand 8i (Management Unit Branjevina, Forest Division Sombor, Public Enterprise Vojvodinašume) using dendrochronological methods. Analyses using a simple Pearson's correlation showed the higher correlation between oak growth and SPEI (Standardized Precipitation Evapotranspiration Index), RDI (Reconnaissance Drought Index) and PDSI (Palmer Drought Severity Index) in the growing season in comparison to simple variables such as mean monthly temperature of monthly sum of precipitation. To date, indices SPEI and RDI are not used to a greater extent in dendrochronological studies. Given their characteristics that they are used for monitoring of drought, and that among the 15 climate variables provide significant correlations for the main months (April to August) during growing season, they should be seriously considered in the future understanding of the impact of drought on forests.

The City of Belgrade is in the process of establishing a new waste management system through a public-private partnership. The project includes the construction of a municipal waste to energy recovery system. The recovery system is designed as a combined heat and power municipal solid waste mass burn incinerator. The impact of utilizing residual municipal solid waste for the generation of heat and power in lieu of coal and natural gas was assessed in terms of the reduction of greenhouse gas emissions. The contributions of energy derived from the waste to energy facility to the total energy consumption in Belgrade were also evaluated.

Mining of material by a bucket wheel excavator is a very complex physical physical-mechanical process. Indicators of the effectiveness of this process depends on a number of various factors, of which in particular may be emphasized: physical-mechanical characteristics of the material to be mined, mode of excavator operation and selection of block technological parameters, slice and cut, and the geometry of the buckets and teeth, etc. A particular problem occurs in the excavation of materials with increased strength, which is often the case in our opencast mines. Sizing of excavator specific digging forces towards smaller masses of extremely hard material is irrational and a solution should be sought either in the excavation of these masses by other equipment or by optimization of bucket wheel excavator operation i.e. in the selection of the optimal type of cut and parameters of slices in order to reduce resistance to digging, reducing energy consumption and reducing the dynamic effects on the structure of the bucket wheel excavator. Current research of this issue, it was found that certain improvements in the operation of the bucket wheel excavator on the mining of materials with increased strength can be achieved by optimizing of some structural and technological parameters, whose main goal is virtually increasing the available cutting forces of the excavator and maximum utilization of the available options with maximum protection of the excavator from the adverse impact of dynamic impacts during operation. Type and parameters of cut are the basic technological parameters that contribute to optimizing may affect: reduction of mining resistance in materials with the increasing strength, increasing the capacity of the bucket wheel excavator, minimizing energy consumption and more favorable dynamic behavior of excavator structure. It is also the subject of this thesis, and the primary goal through conducted researches is to define methodology to be used during selection and the optimal use of bucket wheel excavators in opencast mines in the working environment with the increased resistance to mining. Researches within this thesis were implemented at the theoretical and experimental levels. In this way was perceived an open and determined problem, was reviewed possible, selected optimal solutions, and carried out in practice checkups of results obtained in the concrete conditions of the working environment. Field tests, analysis of the obtained results and optimization of cutting parameters during the mining of materials with increased strength in the opencast mine Gacko has shown that the best effects of excavator operation are achieved with vertical cut and thickness of 0.20 m, width 0.30 m, i.e. with the slewing speed of bucket wheel boom of 24 m/min. It has been demonstrated that it is necessary to change the existing mining technology by the bucket wheel excavator, but also with further complex research to set up a methodology of optimizing the structure of the bucket wheel cutting elements. Otkopavanje materijala rotornim bagerom je veoma sloţen fiziĉko-mehaniĉki proces. Pokazatelji efektivnosti tog procesa zavise od velikog broja raznovrsnih ĉinilaca od kojih se posebno mogu istaći: fiziĉko-mehaniĉke karakteristike materijala koji se otkopava, reţim rada bagera i izbor tehnoloških parametara bloka, odreska i reza, geometrije vedrica i zuba itd. Poseban problem se javlja kod otkopavanja materijala povećane ĉvrstoće, što je ĉest sluĉaj na našim površinskim kopovima. Dimenzionisanje specifiĉne sile kopanja bagera prema manjim masama izuzetno ĉvrstog materijala je neracionalno i rešenje treba traţiti ili u otkopavanju ovih masa drugom opremom ili optimizaciji rada rotornog bagera tj. izboru optimalne vrste reza i parametara odreska u cilju smanjenja otpora na kopanje, smanjenja potrošnje energije i smanjenje dinamiĉkih uticaja na konstrukciju rotornog bagera. Dosadašnjim istraţivanjima ove problematike, ustanovljeno je da se izvesna poboljšanja u radu rotornog bagera na otkopavanju materijala sa povećanom ĉvrstoćom mogu postići optimizacijom odreĊenih konstruktivnih i tehnoloških parametara, ĉiji je osnovni cilj praktiĉno povećanje raspoloţive rezne sile bagera i maksimalno iskorišćenje raspoloţivih mogućnosti bagera uz maksimalnu zaštitu bagera od nepovoljnih dinamiĉkih udara tokom rada. Vrsta i parametri reza su osnovni tehnološki parametri ĉijom se optimizacijom moţe uticati na: smanjenje otpora kopanju u materijalima sa povećanom ĉvrstoćom, povećanje kapaciteta rotornog bagera, minimizaciju potrošnje energije i povoljnije dinamiĉko ponašanje konstrukcije bagera. To je ujedno i predmet istraţivanja ove disertacije, a osnovni cilj je da se kroz sprovedena istraţivanja definiše metodologija koja će se koristiti pri izboru i optimalnom korišćenju rotornih bagera na površinskim kopovima u uslovima radne sredine sa povećanim otporom kopanju. Istraţivanja u okviru doktorske disertacije su realizovana na teorijskom i eksperimentalnom nivou. Na taj naĉin je sagledan, otvoren i determinisan problem, sagledana moguća i odabrana optimalna rešenja i izvršena praktiĉna provera dobijenih rezultata u konkretnim uslovima radne sredine. Terenska ispitivanja, analiza dobijenih rezultata i optimizacija parametara reza pri otkopavanju materijala sa povećanom ĉvrstoćom na površinskom kopu Gacko pokazala su da se najbolji efekti rada rotornog bagera postiţu sa vertikalnim rezom debljine 0,20 m, širine 0,30 m, odnosno sa brzinom obrtanja strele rotora od 24 m/min. Dokazano je da je neophodno promeniti postojeću tehnologiju otkopavanja rotornim bagerom, ali i daljim kompleksnim istraţivanjima postaviti metodologiju optimizacije konstrukcije reznih elemenata rotora.

Vrsta i parametri reza su osnovni tehnološki parametri ĉijom se optimizacijom moţe uticati na: smanjenje otpora kopanju u materijalima sa povećanom ĉvrstoćom, povećanje kapaciteta rotornog bagera, minimizaciju potrošnje energije i povoljnije dinamiĉko ponašanje konstrukcije bagera. To je ujedno i predmet istraţivanja ove disertacije, a osnovni cilj je da se kroz sprovedena istraţivanja definiše metodologija koja će se koristiti pri izboru i optimalnom korišćenju rotornih bagera na površinskim kopovima u uslovima radne sredine sa povećanim otporom kopanju. Istraţivanja u okviru doktorske disertacije su realizovana na teorijskom i eksperimentalnom nivou. Na taj naĉin je sagledan, otvoren i determinisan problem, sagledana moguća i odabrana optimalna rešenja i izvršena praktiĉna provera dobijenih rezultata u konkretnim uslovima radne sredine. Terenska ispitivanja, analiza dobijenih rezultata i optimizacija parametara reza pri otkopavanju materijala sa povećanom ĉvrstoćom na površinskom kopu Gacko pokazala su da se najbolji efekti rada rotornog bagera postiţu sa vertikalnim rezom debljine 0,20 m, širine 0,30 m, odnosno sa brzinom obrtanja strele rotora od 24 m/min. Dokazano je da je neophodno promeniti postojeću tehnologiju otkopavanja rotornim bagerom, ali i daljim kompleksnim istraţivanjima postaviti metodologiju optimizacije konstrukcije reznih elemenata rotora.

Comprehensive analysis of the quality of solids, depending on the application, includes: technical analysis, elemental analysis, analysis of the macrocomponents and microcomponents. A special analytical task is the analysis of anions in a complex matrix of solid samples. In literature and in analytical practice there are a number of methods for the determination of halogens, from classic to contemporary (instrumental), which differ according to the principles of work, and according to criteria that characterize the analytical techniques of which accuracy and reproducibility should be allocated. The subject of the work of this doctoral thesis are halogen elements in coal. Halogen elements in coal are present in low concentrations, but the impact of these elements on the environment and human health is of particular importance. Research in this thesis are designed in the field of analysis of the halogen elements in coal, the results of pyrohydrolityc methods for the determination of halogens, as well as on the application of experimental design for the development of analytical methodologies. The aim of this doctoral thesis was to establish methodology and determine the conditions for simultaneous determination of fluorine, chlorine and bromine in coal. Within this dissertation statistical methods were applied for the plan and for conducting experiments, and techniques for processing and analysis of results. Applying fractional factorial design, the influence of six variables on coal combustion in oxygen bomb and absorption of gaseous compounds during combustion was investigated. The analyzed variables were oxygen pressure, catalysts, combustion aid, type of absorbent solution, reducing agent and bomb cooling time. The concentration of ions in the absorption solution was measured by ion-selective electrode (the fluoride-ion) and by ion chromatography. The results of fractional factorial design were analyzed using Pareto-graphics, graphics of main effects and interaction plots. It was found that with the addition of the catalyst and with the increase of pH value of the absorption solution the concentration of halide ions in the absorption solution decreases. On the other hand, increase of oxygen pressure and the addition of combustion aid, increases the separation of halogens from the coal during combustion in an oxygen atmosphere. On the basis of preliminary studies, oxygen pressure and combustion aid were examined in more detail by using response surface methodology. Results of the optimization experiments were discussed using response surface plots, estimateted regression coefficients and analysis of variance. Since the optimum conditions for the determination of fluorine and chlorine differed, the group parameter - total halogens in coal (TCX) was defined. Total halogen in coal are expressed in terms of chlorine and it was chosen because it is the dominant halogen element in coal. The optimal parameters for the determination of halogens in coal were 0.5 g of coal samples, oxygen pressure of 2.5 MPa, 5 cm3 of H2O as the absorption solution, 5 cm3 of H2O2 as reducing reagent, 150 µL of mineral oil as the combustion aid, and a cooling interval of 15 minutes after combustion. Validation of proposed method was performed by determination of fluorine and chlorine in in-house prepared reference coal samples and in certified reference materials (BCR 460 and NIST 1632c). The relative standard deviation of determination of fluorine was less than 5.0%, and recovery was greater than 95%. The relative standard deviation of determination of chlorine was less than 6.0%, and recovery greater than 85%.The method was sensitive, with good reproducibility and accuracy. The proposed method was applied for determination of sulfur in coal. Validation of a method for determining the sulfur content is shown that the standard deviation of measurements was less than 6%, with a good reproducibility. The limit of detection (LOD) and limit of quantification (LOQ) is estimated for ion chromatography measurements and standard deviation of determining ions in the mixed standard solution of the lowest concentration. It has been found that the LOD and LOQ for fluorine were 0.4 mg / kg and 1.26 mg / kg; chlorine 0.84 mg / kg and 2.79 mg / kg; sulfur 2.2·10-5 % and 7.2·10-5 %. The proposed method was applied for the determination of fluorine, chlorine and sulfur in Kolubara and Kostolac coal samples. Analiza kvaliteta ĉvrstih materijala, u zavisnosti od namene, obuhvata: tehniĉku analizu, elementarnu analizu, analizu makrokomponenata i mikrokomponenata. Poseban analitiĉki zadatak predstavlja analiza anjona u sloţenoj matrici ĉvrstog uzorka. U literaturi i analitiĉkoj praksi postoji veliki broj metoda za odreĊivanje halogenih elemenata, od klasiĉnih do savremenih (instrumentalnih), koje se razlikuju kako po principima rada, tako i po kriterijumima koji karakterišu analitiĉke tehnike, od kojih treba izdvojiti taĉnost i reproduktivnost. Predmet rada ove doktorske disertacije su halogeni elementi u uglju. Halogeni elementi u uglju su prisutni u niskim koncentracijama, ali je uticaj ovih elemenata na ţivotnu sredinu i zdravlje ljudi od posebnog znaĉaja. Istraţivanja u okviru ove disertacije obuhvataju analizu halogenih elemenata u uglju, rezultate istraţivanja pirohidrolitiĉke metode za odreĊivanje halogenih elemenata, kao i primenu eksperimentalnog dizajna za razvoj analitiĉkih metodologija. Cilj ove doktorske disertacije bio je da se utvrdi metodologija i odrede uslovi za istovremeno odreĊivanje fluora, hlora i broma u uglju. U okviru ove disertacije primenjene su statistiĉke metode za organizaciju i izvoĊenje eksperimenata, i tehnike za obradu i analizu dobijenih rezultata. Primenom frakcionisanog faktorijskog dizajna ispitan je uticaj šest promenljivih na sagorevanje uglja u kiseoniĉnoj bombi i apsorpciju gasovitih jedinjenja koja se tokom sagorevanja izdvajaju iz uglja. Ispitan je uticaj poĉetnog pritiska kiseonika, dodatak katalizatora i pomoćnog goriva na sagorevanje uglja, kao i tip apsorpcionog rastvora, dodatak redukcionog agensa i vreme hlaĊenja bombe nakon sagorevanja na apsorpciju gasovitih jedinjenja. Koncentracija jona u apsorpcionom rastvoru merena je potenciometrijski jon-selektivnom elektrodom (za fluorid-jon) i jonskom hromatografijom. Rezultati frakcionisanog faktorijskog dizajna su analizirani pomoću Pareto-grafika, grafika glavnih efekata i dijagrama interakcije parametara. UtvrĊeno je da se dodatkom katalizatora i povećanjem pH vrednosti apsorpcionog rastvora smanjuje koncentracija halogenid-jona u apsorpcionom rastvoru. S druge strane, povećanjem poĉetnog pritiska kiseonika i dodatkom pomoćnog goriva, povećava se izdvajanje halogenih elemenata iz uglja tokom sagorevanja u atmosferi kiseonika. Na osnovu rezultata preliminarnih istraţivanja, pritisak kiseonika i zapremina pomoćnog goriva su detaljnije ispitani primenom metodologije odgovora površine. Rezultati optimizacionih eksperimenata razmatrani su analizom grafika odgovora površine, procene regresionih koeficijenata i analize varijansi. Pošto su se optimalni uslovi za odreĊivanje fluora i hlora razlikovali, definisan je grupni parametar - ukupni halogeni u uglju (engl.- total halogen in coal, TCX). Ukupni halogeni u uglju su izraţeni preko hlora, a hlor je izabran iz razloga što predstavlja dominantan halogeni element u uglju. Optimalni uslovi metode odreĊivanja ukupnih halogena u uglju sagorevanjem u kiseoniĉnoj bombi su: pritisak kiseonika od 2,5 MPa, zapremina pomoćnog goriva od 150 µL, apsorpcioni rastvor je voda uz dodatak 0,5 % rastvora vodonik-peroksida i hlaĊenje kiseoniĉne bombe u ledenom kupatilu 15 minuta nakon sagorevanja uglja. Masa uzorka je bila 0,5 g. Validacija predloţene metode za odreĊivanje fluora i hlora sagorevanjem u kiseoniĉnoj bombi uraĊena je analizom internih referentnih uzoraka uglja i sertifikovanih referentnih ugljeva (BCR 460 i NIST 1632c). Relativna standardna devijacija odreĊivanja fluora bila je manja od 5,0 %, a procenat izdvojenog fluora u odnosu na referentnu vrednost veći od 95 %. Relativna standardna devijacija odreĊivanja hlora bila je manja od 6,0 %, a procenat izdvojenog hlora veći od 85 %, što znaĉi da je odreĊivanje fluora i hlora predloţenom metodom precizno i reproduktivno. Predloţenom metodom je odreĊen i sadrţaj sumpora u uglju. Validacija metode za odreĊivanje sumpora je pokazala da je standardna devijacija merenja manja od 6 %, uz dobru ponovljivost.

In synergy with other socio-economic risks, the effects of climate change pose contemporary structural challenges that can not be considered only as an environmental issue. They affect the general development and therefore make the adaptive capacity of a population uncertain in the following decades. The subject of this dissertation comprises the development of a new decision support model for the selection of local level climate change adaptation measures. Considering the nature of management issues in climate policies, which involves decision-making under the conditions of uncertainty, the model employs adaptive management principles. It was designed to help decision-makers in selection of adequate adaptation measures, and to enable monitoring of the implementation process. The key objective of the research is fulfilled by developing a model for the selection of priority adaptation measures. The model is based on scenarios of the synergistic influence of diverse sets of measures on the observed system vulnerability. It takes into account climate projections and relevant biophysical and anthropogenic factors. The model relies on a combination of several methodological approaches. The scenario method was used for the selection of adaptation measures. It is based on the assessment of the simultaneous contribution of a group of measures to the reduction of vulnerability of the observed climate impact, by forming a conditional probability diagram using Bayesian networks. Through the analysis of the likelihood of diverse states of the observed group of criteria, it is possible to examine the effect of individual measures (or sets of measures) adaptation capacity, as a result of the joint probability distribution of all criteria in the network. The analytical hierarchical process (AHP) was used to quantify the distinct qualitative relationships between the risk criteria of the observed climate impact and the adaptation measures. A GIS is used to calculate the specific values of the criteria on the network, to profile the vulnerability, sensitivity, adaptation capacity and exposure index, as well as for data integration. The model can improve the decision-making in adaptation planning process. As the results are expressed as a probability distribution for each alternative, the model can help decision makers predict the chances of achieving desired effects of selected measures, and develop detailed programs at the local level to increase their efficiency. The model is also capable to transparently monitor the application process and facilitate the development of appropriate capacities for the purpose in local communities. In this respect, the developed model also provides a methodological contribution for improving the planning framework for the local adaptation project management.

Considering the nature of management issues in climate policies, which involves decision-making under the conditions of uncertainty, the model employs adaptive management principles. It was designed to help decision-makers in selection of adequate adaptation measures, and to enable monitoring of the implementation process. The key objective of the research is fulfilled by developing a model for the selection of priority adaptation measures. The model is based on scenarios of the synergistic influence of diverse sets of measures on the observed system vulnerability. It takes into account climate projections and relevant biophysical and anthropogenic factors. The model relies on a combination of several methodological approaches. The scenario method was used for the selection of adaptation measures. It is based on the assessment of the simultaneous contribution of a group of measures to the reduction of vulnerability of the observed climate impact, by forming a conditional probability diagram using Bayesian networks. Through the analysis of the likelihood of diverse states of the observed group of criteria, it is possible to examine the effect of individual measures (or sets of measures) adaptation capacity, as a result of the joint probability distribution of all criteria in the network. The analytical hierarchical process (AHP) was used to quantify the distinct qualitative relationships between the risk criteria of the observed climate impact and the adaptation measures. A GIS is used to calculate the specific values of the criteria on the network, to profile the vulnerability, sensitivity, adaptation capacity and exposure index, as well as for data integration. The model can improve the decision-making in adaptation planning process. As the results are expressed as a probability distribution for each alternative, the model can help decision makers predict the chances of achieving desired effects of selected measures, and develop detailed programs at the local level to increase their efficiency. The model is also capable to transparently monitor the application process and facilitate the development of appropriate capacities for the purpose in local communities. In this respect, the developed model also provides a methodological contribution for improving the planning framework for the local adaptation project management.

The starting position of the first part is that technical and technological modernization, in addition to the undoubted benefits, also brings some problems that result in a long-term ecological crisis. One of the key social and environmental problems based on modernization is the issue of the dramatic proportions of rapid population growth in the last few decades. The second part of the paper deals with the problems that follow from rapid population growth, such as preserving the quality of life and environmental quality, as well as the issue of sustainable development. It is pointed out that the growing population rapidly endangers the planet's key resources (deforestation, water, air, and soil pollution, etc.) and that the survival of the human species is at stake. Special attention is paid to the violation of the existing water supplies, which directly threatens the health and physiological survival of people, especially in the big cities of underdeveloped countries. The third part of the paper shows that, among other things, it is essential to develop adequate environmental awareness (ecocentrism), which should encourage both the politically powerful and ordinary people to change their habits and to devote more attention to the preservation of the environment.

The immense attention that has been given to environmental issues in recent years can be attributed to a large amount of scientific evidence, according to which the existing and projected patterns of economic activities cause its degradation, which in turn questions the future of these economic activities. Development in the 21st century should be based on the rational use of natural resources, with minimal reversible damage to the environment. The development understood in this way is the starting point of the European Union's Common Agricultural Policy. Appropriate environmental measures have been prescribed for the realization of the planned developmental path, with the obligation to implement and adhere to them gaining more importance. Since its establishment, the Common Agricultural Policy has not focused on the environmental impact of agricultural production. More precisely, the possible environmental consequences of agricultural production on the environment had not been considered, which in turn led to significant problems. The problems that arose were the basis for the development of the environmental policy which defined the principles, measures and determinants for environmental protection and its improvement in the course of time. The analysis of measures and tools in the field of environmental protection, which are an integral part of the European Union's Common Agricultural Policy, was performed in order to point out their importance through reforms of the Common Agricultural Policy in preventing risks of environmental degradation and improving agroecosystem sustainability. In the part of the dissertation related to empirical research, in terms of agricultural development and environmental quality, the degree of interdependence of ecological and economic performances of agricultural production at the level of the EU member countries was analyzed. The EU countries have been classified into homogeneous groups through cluster analysis, according to the achieved level of environmental performance, thus showing the position of the countries between groups in relation to the achieved environmental performance, highlighting the recommendations for further direction of agricultural production and actions in combating climate change which is, needless to say, harmful to the environment. Based on the analysis of predictions of future values and the extent of environmental consequences, climate change has been recognized as an environmental indicator with the most influential negative impact on the environment.

Several unfavorable processes are taking place in the field of energy: large capacities of renewable energy sources (with variable and unpredictable availability) are being put into operation without detailed analises of its influence on electric power systems (EPS), large thermal and nuclear power plants (those who ensured the stability and reliability of EPS) are being closed, energy transmission systems are being cut off for political reasons as well as the import of some most important energy sources (natural gas, coal, oil). Those processes significantly change the role of hydropower plants in the EPS. All types of hydropower plants are becoming specialy important, especially those with water storage reservoirs and large installed capacities. Their role in regulating and ensuring the reliability of EPSs is significantly increasing. Beside the storage hydropower plants, pumped-storage hydropower plants become more important due to their possibilities to regulate the system in conditions of sudden changes of the power of wind and solar power plants,. The article discusses the processes in the world in terms of hydropower, the available hydropower potential in Serbia, as well as the real possibilities for its utilization. The most important hydropower systems remaining for construction are presented in the article. It is pointed out the necessity to clearly delineate which energy sources are really renewable and which contribute to the reduction of greenhouse gas. The importance of spatial planning which should protect the spaces necessary for the construction of hydropower systems is particularly emphasized. U svetu se odigravaju nepovoljni procesi u energetici: nedovoljno prostudirano se uvode u pogon velike snage obnovljivih izvora energije čija je raspoloživost vrlo promenljiva i nepredvidiva, zatvaraju se velike termoelektrane i nuklearne elektrane koje su obezbeđivale stabilnost i pouzdanost elektroenergetskih sistema, iz političkih razloga se prekidaju transferi energije i uvoz nekih ključnih energenata (prirodni gas, ugalj, nafta). Ti procesi radikalno menjaju ulogu hidroelektrana u elektroenergetskim sistemima. Sve vrste hidroelektana dobijaju na posebnom značaju, a posebno akumulacione hidroelektrane velikih instalisanih snaga. Značajno se povećava njihova uloga u regulaciji i obezbeđivanju pouzdanosti elektroenergetskih sistema. Zbog regulacije sistema u uslovima nagle promenljivosti snaga elektrana koje koriste vetar i Sunce, pored akumulacionih hidroelektrana velikih snaga, veliki značaj dobijaju i reverzibilne, pumpno akumulacione hidroelektrane. U članku se razmatraju procesi u svetu na planu hidroenergetike, raspoloživi hidroenergetski potencijali Srbije, kao i realne mogućnosti za njihovu realizaciju. Prikazuju se ključni hidroenergetski sistemi koji su preostali za izgradnju. Ukazuje se na neophodnost da se metodološki jasno razgraniči koji energetski izvori spadaju zaista u klasu obnovljivih izvora energije, i koji zaista doprinose smanjenju emisije gasova staklene bašte. Posebno se naglašava značaj da se prostornim planovina svih nivoa definišu i obezbede od devastacije i zauzeća prostori koji su neophodni za realizaciju hidroenergestkih sistema.

Posebno se naglašava značaj da se prostornim planovina svih nivoa definišu i obezbede od devastacije i zauzeća prostori koji su neophodni za realizaciju hidroenergestkih sistema.
