This article examines phytoecological aspects of plant groups in the Chebket El Melhassa region (Tiaret-Ouest Algérien) by several types of analysis: biological, biogeographic and statistical. From the plant analysis, a list of 103 taxa distributed in 36 families was compiled, biologically characterized by a dominance of therophytes (45.6%) with species of the Mediterranean biogeographic type 20 species (19.8%) assuming particular importance. The ordination of the plant community was performed in the search for the optimum solution based on correlation with environmental factors, estimated using the phytoindication approach. The results reveal that the plants represented in the community, mostly prefer strongly lit places. Phytoindication shows a warm sub Mediterranean climate. Continentality corresponds to the sub-oceanic climate. The moisture regime ranges from strongly dry to dry soil. The plant community is formed on moderately acid soils. Plants are able to grow on both strongly acidic and neutral soils. The soil is very poor or poor in nitrogen. A four dimension variant of multidimensional scaling procedure was selected as the most appropriate decision. Dimensions selected after nonmetric multidimensional scaling were interpreted by computing weighted average scores of ecological factors for ordination configuration. Four of the plant species clusters were found to be the optimal solution on the basis of the Calinsky-Harabasz criteria. The clusters can be viewed as a functional group. Functional group A is quite diverse and represented by 42 species. This functional group is closest to the community optimum because in all four space dimensions the corresponding cluster is near the origin, which corresponds to the most typical ecological conditions. Species that constitute the group B prefer minimum values of dimension 2. This indicates a preference for illuminated sites with high temperature regime and low soil humidity. This group includes 32 species. A feature of group С is that it is located in the area of maximum values for dimension 2. Thus, this functional group is opposite to functional group B. This indicates a preference of species included in the functional group C for wetter soils. Functional group C comprises 21 species. Functional group D differs considerably from all others in its ecological characteristics. The difference is in the preference for minimum values for measurement 1. This suggests that more acid soils are optimal for a given functional group. Functional group E comprises 8 species.

Author(s): N. V. Voronova,O. Y. Pakhomov,V. V. Gorban’ / Language(s): English / Issue: 2/2005

The aim of the research was to estimate the role of different types of biotopes in a formation of the Aedes vexans high ecological valency. The greatest number of Ae. vexans mosquitoes procreate in basins with the moderate density of larvae (49.6–70.2 %), less mosquitoes procreate in basins with the high one (15.9–19.0 %). The optimal and effective density for the development of mosquitoes larvae in temporary basins of a long while flooded forest of the Dnipro river is 350–1700 specimens/m2, that’s why it is necessary just to pay attention to them during taking measures on reducing their numbers.

BİR SÜREÇ OLARAK HOŞNUTSUZLARIN ÇEVRECİLİĞİ: HİNDİSTAN’DAN SARDAR SAROVAR BARAJI ÖRNEĞİ

Author(s): Defne GÖNENÇ,Alper Almaz / Language(s): Turkish / Issue: 2/2018

In the neoliberal era, which redefines the power relations among the state-market-society-nature, the environmental movements differ in terms of their participants. Arsel, Akbulut and Adaman created the concept of “environmentalism of the malcontent” that moves beyond the distinction between the “environmentalism of the rich,” and the “environmentalism of the poor”. The purpose of this study is to re-evaluate the concept of the “environmentalism of the malcontent”. The study was undertaken by evaluating the participants of the environmental movement against the Sardar Sarovar Dam, located on the Narmada River in India, by undertaking qualitative research methods. Data is collected through individual and group interviews, and non-participant observation method during the field trip undertaken in India. In the article, it is argued that if the environmental movements are elaborated as a process which have transformative effects on its participants, the concept of the “environmentalism of the malcontent” can be used to define the environmentalism of not only the ones with the middle-class qualities, but also that of other groups in the environmental movement.

Biskupi czasów przedrozbiorowych w świetle propagandy antykościelnej prowadzonej przez władze polityczne Polskiej Rzeczpospolitej Ludowej2 w latach 1944–1989

Author(s): Piotr Jaworski / Language(s): Polish / Issue: 2/2016

One of the fundamental ideological goals of communists coming into power in Poland after the end of the World War II was the fight against religion. The goal resulted in the marxist-leninist ideology (based on dialectical and historical materialism) which rejected the existence of God. No wonder that the contemporaneous political authorities supported by the ideology mentioned above towards wide spread devotion of the society treated the Church as the opponent which can make them less powerful. Hence, the People’s Republic of Poland (PRP) authorities used in a different intensity the policy of repression and condemnation against the Church in years 1944–1989. Anti-church propaganda became the crucial element of the government’s policy. The propaganda covered various aspects of life and functioning of the Church.The present article highlights the political propaganda of the PRP and what was carefully underlined was the fact how the propaganda presented particular bishops from old Polish times showing at the same time, based on certain examples, manipulation, lies, and lack of reliability and objectivity of the contemporaneous propaganda.

Changes In Land Cover/Land Use Over The Northeast Region Of India

Author(s): Tongdi Jamir / Language(s): English / Issue: 3/2015

The Northeast region (NER) is rich in biodiversity however it is under increasing pressure due to economic development. With this in backdrop, an attempt is made to investigate the trend in forest cover, shifting cultivation and urbanization. The analysis reveals that annual forest cover shows significant decreasing trend at Nagaland and Manipur while increasing trend is reported at six states. In order to understand the causative factor for increase/decrease, the data related to various forest cover viz., dense, open, scrubs and non-forestland were collected and analysed. The result indicates that except Arunachal Pradesh and Assam, the rest of the state reported increase in dense forest cover. The analysis also shows that area under shifting cultivation has decreased considerably across the NER. This can be ascribed to the afforestation drive, settled agriculture and social forestry etc. In NER, all the major towns show exponentially increase in population growth significant at 99%. Thus, there is a positive correlation between population growth with that of forest cover and urbanization unlike shifting cultivation. The results also show significant decrease in monsoon rainfall and an increase in temperature variables, a part played by change in land cover and land use.

Author(s): Rajko Golić,Marko Joksimović,Ivan M. Potić / Language(s): English / Issue: 2/2015

Tourism is an indicator and the consequence of the development of many countries. Among the priority areas of the tourism strategy are high mountain areas with complex ecosystems. Mountain tourism in Serbia, as well as continental country is one of the leading forms of tourism through various projects stimulated by the state. In the last ten years, build up and expand the ski slopes of Stara planina in eastern Serbia, leading to various, mostly negative changes in the environment. This paper analyzes the changes in the forest areas of the site Babin Zub in years 2000 and 2013, using satellite imagery (Landsat 7 and Landsat 8) and remote sensing software. We used unsupervised multispectral analysis resolution 30 m and obtained data on forest areas. The aim is to draw attention to the change of vegetation cover and degradation of forest areas. Following to the experiences of the world's ski resorts, the paper presents the opportunities and examples of restoration of ski runs, and sustainable forest management in the studied highland area.

Characteristics of the renewable energy sources technology transfer center's building in the context of requirements for the passive standard

Author(s): Marcin Jaczewski,Szymon Firląg / Language(s): English / Issue: 13/2014

The aim of this paper is to present the requirements for the passive standard based on the example of the RES TTC building. The requirements were divided into main energy demand and detailed recommendations for each indicator. The calculations and analyses have shown that to achieve the required energy demand, better solutions than the recommended ones need to be applied, such as air handling units with better heat recovery efficiency. The same applies to the U heat penetration coefficient of heat for the outer partitions. The use of ventilation units with a recommended efficiency of 75% does not guarantee achieving a passive standard.

Communist populism in Hungary

Author(s): Attila Antal / Language(s): English / Issue: 4/2018

According to Cas Mudde, we live in a “populist Zeitgeist”. The paper argues that not just the 21st, but also the 20th century is about populism. In the first section I elaborate the theoretical background of populism, which is claimed to be a never-ending phenomenon: here, various notions of populism are analysed; I investigate the relationship between democracy and populism; and I refer to the biopolitical framework of populism (called biopopulism) as well. This theoretical framework will be used to analyse Communist populism in Hungary. I elaborate the populism of the Horthyera (1920-1944) in the context of Communist populism. Then I analyse the case of Communist populism in Hungary (1948-1989) according to the following aspects: in the context of the working class and the bourgeois elite; the biopolitical character of the regime; goulash Communism as populist legitimacy; and the viewpoint of socialist patriotism. The main aspect of Communist populism is summarized at the end of the third section, and I briefly refer to the afterlife of Communist populism as a nostalgic phenomenon. The regimes analysed in this study aimed to govern the entire life of the citizens, which is why biopopulism is a useful analytical concept. The biopopulist framework shows that the investigation of the historical backgrounds of populism is necessary to understand contemporary populist tendencies.

Comparative Analysis Of The Flow Activity Of The Homoljska Potajnica Intermittent Spring

Author(s): Nikola Igračev / Language(s): English / Issue: 1/2014

Homoljska Potajnica belongs to the type of a very rare, intermittent or rhythmic springs which appear exclusively in karst areas. It is one of the three known springs of this type in Serbia, while it is believed to be only about fifty of these in the rest of the world. As a rare karst and natural phenomenon, Homoljska Potajnica was a subject of interest for numerous researchers and geomorphologists in Serbia. Due to a very complex problem of occurence and the principle of functioning, to get the reliable data of how intemittent springs work, it is neccesarry to provide a continious observations, ussually in a long term period. This paper presents the results of the measurements of spring's flow activity and water discharge, taken in 2012. and 2013. These were carried out for comparison with the results of previous research, with an aim to determine possible changes in dynamics and mechanisms of spring's functioning in the past. One of the goals is to relate the annual precipitation regime with the intensity and frequency of spring activity, to try to determine the specific model of the spring's functioning. Another goal is to emphasize the need for continious observation in order to obtain the relevant data about the evolution of this rare natural phenomenon.

CURRENT STATE AND TRENDS FOR REACHING CIRCULARITY OF MATERIALS IN SELECTED COUNTRIES FROM THE BALKAN REGION

Author(s): Aneta Vasiljevic-Shikaleska,Martin Stojanovikj,Biljana Gjozinska / Language(s): English / Issue: 18/2017

The main objective of the paper is to evaluate the activities undertaken and results achieved so far for reaching the targets of green economy and its component - circular economy in R. Macedonia, Serbia, Slovenia and Croatia by studying the resource productivity, total waste generation, waste intensity and recycling rate, as one of the leading indicators for the circulating behavior of the materials. Also, an attempt to calculate the values of a recently suggested potential composite indicator for assessing the progress of circularity has been made. The results show that Slovenia and Croatia have higher resource productivities than R. Macedonia and Serbia. Similar results were obtained for the total waste intensity and recycling rates of the municipal waste. Although it was observed that the largest amounts of waste were generated in Slovenia due to the more intensive economic growth , at the same time Slovenia showed the lowest waste intensity (far below 1) implying that decoupling of waste generation from economic growth is more intense than that in the other investigated countries. The composite circularity indicator for R. Macedonia, and particularly for Serbia, has very low values due to very low recycling rates of the municipal waste (below 1%), lower GDP per capita and on the other hand very high CO2 emissions. As expected, the highest values of the circularity indicator were obtained for Slovenia implying that Slovenia is the most efficient in terms of energy and materials use. It can be concluded that the transition towards a circular economy in the investigated countries is taking place and the changes are more pronounced for the case of Slovenia, where as Croatia, and especially R. Macedonia and Serbia are lagging behind.

Current State of Studying Precipitation Acidification in Serbia

Author(s): Goran Anđelković,Radomir Talijan / Language(s): English / Issue: 4/2015

Basic relations between the state of air pollution and their effects on chemistry of precipitation were introduced in this paper. Changes in the composition of atmosphere were defined by numerous chemical elements and compounds different in character which also affect the phenomenon of acidification and alkaline processes. The interconnected sources of emission, relations between urban and rural, the regime of rain measuring system and climate elements combined as whole give us more complete image of the global phenomenon and its effects on cities as a contemporary social development first of all caused by industrialization , its dependance upon fosil sources of energy and demographic pressure. Characteristics of main pollutants were considered as well as their ability to modify atmospheric conditions, but also the influence of climate elements on those conditions, ph rainfall average value movement, seasonal and daily variations, the influence of industrial zones and agglomeration on the conditions in the area much wider than emitters.

Daugiakriterių metodų panaudojimas vertinant darnų vystymąsi

Author(s): Roberta Kareivaitė / Language(s): Lithuanian / Issue: 1/2012

The relevance of this topic is reflected in new economic thinking of the current times, which argues that global progress can be achieved only by coordinating economic efficiency, social justice, environment protection and institutional role. The coordination of these principles into one system is the concept of sustainable development, which is based on the idea that the current generation must satisfy its needs by preserving the possibility for future generations to satisfy theirs. This view is as important in Lithuania as it is worldwide. Analyzing the situation of sustainable development in Lithuania, one misses the information which consistently evaluates sustainable development and uses the concrete multi-criterion method, one also misses integrated indexes which would allow to evaluate the sustainable development of the country. The object of the article - the evaluation of sustainable development. The purpose of the article – to evaluate sustainable development situation in Lithuania by using multi-criteria assessment methods. To achieve this purpose the following tasks were set: 1. To introduce the theoretical aspects of multicriteria methods; 2. To find out the methodology of calculating integrated sustainable development index; 3. To analize Lithuania’s sustainable development situation during the years 2000-2010. Research methods: systemic analysis, synthesis, comparison and generalization of scientific literature sources, structural, dynamic and causal analysis of statistical data. Concrete results of the research. The assessment of Lithuanian economic development in terms of sustainable development allows to identify the weak points in the economic development of the country, to analyze the changes and tendencies, to look for the possible solutions for economic, social, environmental and institutional problems. The were used four multi-criteria methods in this article: SAW (Simple Additive Weighting), TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), COPRAS (Complex Proportional Assessment) and Integrated method. The best methods which can be chosen to evaluate sustainable development situation in Lithuania are TOPSIS and integrated methods. After conducting the analysis of sustainable development in Lithuania it was established that during the years 2000-2003 and during economic crisis in 2009 it was given bigger attention to institutional dimension to accieve important tasks (like joining European Union, solving economic problems, etc.). In 2009 economic development inex decreased by 34,39 per cent, social development index decreased by 6,13 per cent, environmental development index increased by 10,16 per cent while institutional development index increased by 41,93 per cent. Summarizing it can be concluded that sustainable development is a long-term strategy, ensuring clean and healthy environment as well as an increasing standard of living for the present and future generations.

DEKARBONIZACJA EUROPEJSKICH GOSPODAREK W UJĘCIU PRZESTRZENNYM

Author(s): Ewa Jankowska / Language(s): Polish / Issue: 45/2/2016

Decarbonization, in the light of environment protection policy, is a process which consists in reducing and, eventually, stopping completely CO2 emissions to atmosphere. The European Union targets a reduction of emissions of noxious greenhouse gases by 40% in 2030 and by 80–95% in 2050 versus 1990 levels. For those member states whose energy production is mainly coal-based, this may mean defining a completely new model of functioning on the power market. This article aims to identify experience and challenges in the area of economies decarbonization, especially the use of energy from renewable sources. Results of empirical studies performed based on a set of panel data from 2005–2012 were used as the basis for conducting scientific analyzes and interpretations. The study was carried out based on selected environmental indicators, GDP per capita and the share of renewable power sources in the energy industry structure. In the article, a note was also made concerning the spatial differentiation of electricity production from renewable sources.
