Sustainable development in karst areas should be adapted to its specificities and take into account its vulnerability. The assessment of the development potential and management of karst areas is of ...great importance in Slovenia. This book presents the analyses of the impact of landscape features on the land use and sustainable development in a marginal Slovenian karst landscape ‒ Bela krajina. In order to draw attention to the combination of social perspectives with natural conditions for an integrative view of the karst landscapes, three approaches were used: 1. assessment of the degree of human disturbance to the karst landscape, 2. analyses of land use dynamics, and 3. quantitative and qualitative analyses of the sustainable development of Bela krajina. Karst landscape features affect sustainable development of the study region both positively and negatively. According to local stakeholders the positive effects are mainly connected with tourism, and the negative effects are mainly connected with hampered agriculture. The main message is that karst landscape features should not only be seen as limiting factors, but also for their development potential.
V Ljubljani je glavni vir onesnaževanja zraka z NO2 promet, zato se prispevek osredotoča na prometno obremenjevanje zraka v treh različnih tipih mestnega prostora: urbanem ozadju, na odprtem prostoru ...ob cestah in v cestnih koridorjih. Predstavljene so tudi meritve koncentracij prečno na glavno cesto. Prispevek primerja rezultate meritev NO2 v Ljubljani v merilnih obdobjih poleti 2005 in 2013 ter skuša pojasniti vzroke za razlike v obsegu onesnaženosti različnih tipov mestnega prostora in pomemben upad koncentracij v vseh obravnavanih tipih.
The second book in the new collection Karstology in Development Challenges in the Karst brings together the findings obtained in planning and construction of motorways in the Karst. More than 350 new ...caves were opened up in the final wave of construction. This was followed by studies on arranging karstic features for tourism and their management. We also selected studies on karstic ecology, in which we made use of biological and microbiological research. At the end there is a summary of everything we need to take into account in planning different encroachments in karstic areas.
A good knowledge of the natural and cultural heritage of karst is a precondition for the rational planning of life on it. We try to organize the knowledge to make it as useful as possible for ...planners. We are involved in individual projects related to the regional planning, water supply systems, the construction of transportation infrastructure, the closure of landfills in karst areas, the collection of data on karst caves and their protection, karst ecology and determining the extent of human influence on the karst underground. A new book series Karstology and development challenges on karst was designed to present the results of completed and new projects to a broader public.The first book with the subtitle Water contains selected directly applicable research studies on karst waters, their characteristics, endangerment, and protection. It is composed of ten chapters, which can be grouped into three main themes. In the introduction the importance, characteristics and vulnerability of karst aquifers are presented,then various case studies of pollution and endangerment are described (traffic, landfills, military objects, flooding), and at the end some guidelines for the protection of karst water sources are summarized. The book is a bilingual publication in Slovene and English. It is aimed at a broad circle of users, researchers, students and planners.
Ljubljansko polje is a juncture of numerous human activities. The source of drinking water for about 300,000 residents, it holds one of the most important bodies of groundwater in the country. ...Unfortunately, the influences of urbanization, agriculture and industry that threaten and burden it are reflected in the quality and quantity of the groundwater.
The modern way of life requires the exploitation of natural resources, which leads to a significant deterioration of the environment and can even endanger human health.The basic hypothesis is that ...the population of Slovenia in general is still too inadequately informed and insufficiently environmentally educated and aware about water as a natural resource to have the motivation and capability to actively participate in the protection of water as a natural resource.Most people support environmental protection in principle, especially declaratively, since this is a socially approved action. However, when faced with restrictions that would interfere with their way of life by limiting their activities or increasing their expenses, their enthusiasm decreases rapidly. And the closer we get to actions we could define as “environmentally active,” the fewer people are actually prepared to protect the environment. Possibly a fifth of the population can be defined as people who favour environmental protection and consider it a value for which they themselves are willing to do something.The survey showed that level of education is very significant relative to people’s response to environmental problems and that the more educated are more environmentally friendly.

Safeguarding Drinking WaterLjubljana's water resources lie in the immediate vicinity of built-up urban areas or even below them. For decades, they have been safeguarded as water-protection areas, ...which are specified by implementing regulations. However, formal protection through regulations is insufficient if the goal is to manage these sources in a sustainable manner. One of the most important goals of sustainable management is maintaining suitable provision of fresh drinking water without using any technological procedures to
A bacterial model system (Pseudomonas putida DSM 50026) was used in this research to assess toxicity of the environmentally relevant concentrations of mercury species (MeHg and Hg(II)) that represent ...important pollutants of aquatic ecosystems at sites of industrial or mining activities. In addition to direct monitoring of bacterial growth, we also analyzed fatty acid profiles of exposed and non-exposed cultures to determine possible toxic effects manifested on membrane level. The results showed that exposure of P. putida to Hg(II) in concentrations of 0.2-200 μg/L did not have any significant effects on growth nor fatty acid composition of exposed bacterial culture. On the other hand, when bacteria were exposed to up to 1600-times lower concentrations of MeHg (0.12-12.5 μg/L), growth inhibition as well as significant changes in fatty acid composition were detected. Observed adaptive membrane changes due to MeHg exposure were similar to those associated with responses to organic solvents and some other membrane-disrupting compounds.
V raziskavi smo na bakterijskem modelu (Pseudomonas putida DSM 50026) analizirali strupenost okoljskih koncentracij anorganske (Hg(II)) in organske (MeHg) oblike živega srebra, ki predstavljata pomembna vira onesnaženja vodnih ekosistemov v bližini nekaterih industrijskih in rudarskih območij. Poleg neposrednega spremljanja bakterijske rasti smo analizirali tudi maščobnokislinske profile izpostavljenih bakterijskih kultur in jih primerjali s tistimi, ki živosrebrovima spojinama niso bili izpostavljeni. Rezultati so pokazali, da izpostavitev P. putida Hg(II) v koncentracijah med 0,2 in 200 μg/L ne inhibira rasti, niti ne vpliva na maščobnokislinsko sestavo bakterijskih membran. Nasprotno pa je izpostavitev celic do 1600-krat nižjim koncentracijam MeHg povzročila tako upočasnitev rasti kot tudi prilagoditvene spremembe na membranskem nivoju. Slednje so bile podobne kot tiste, opažene ob izpostavitvi bakterij organskim topilom in nekaterim drugim spojinam, ki motijo integriteto membran.
Cestni promet povzroča emisije izpušnih plinov in delcev, ki nastanejo kot posledica izgorevanja goriv v motorjih z notranjim izgorevanjem pogonskih goriv in nekaterih drugih procesov. Zrak ob cestah ...je zato obremenjen z onesnaževali kot so dušikovi oksidi, ogljikov monoksid, lahko hlapni ogljikovodiki, delci in še nekateri drugi. Spremljanje stanja kakovosti ozračja ob cestah je z vidika proučevanja vplivov prometa na kakovost zraka ključno pri ocenjevanju okoljskih vplivov prometne dejavnosti. Prispevek govori o uporabi difuzivnih vzorčevalnikov pri merjenju onesnaženosti ozračja z dušikovim dioksidom ob večjih in manjših cestah na območju Mestne občine Ljubljana (MOL).
Garden-plot areas spontaneously developed and were distributed across the entire flat area of Ljubljana. Due to a new, more urban lifestyle and a policy change by the city authorities, the area of ...garden plots fell considerably at the end of the twentieth and the beginning of the twenty-first centuries. The most recent analysis of plot gardening in the City of Ljubljana, which surveyed 302 plot gardeners, showed that the overall infrastructure available in garden-plot areas is relatively poor. This activity is mainly practiced by older and lower-income people, most of whom live in apartment buildings. Due to pesticide residues and heavy metals in the soil and produce, as well as groundwater contamination, plot gardening poses a threat to public health and the environment. The 2008 Draft Ljubljana Zoning Implementation Plan foresees a reduction in the total area of plot-gardening areas by nearly half~however, even the planned community garden plots include some that do not meet the minimum location standards. Some garden-plot areas are problematic primarily because they are located close to major traffic routes. In the future, plot gardeners will have to be more systematically informed and educated about proper and safe use of fertilizers and pesticides.
