Namen članka je predstaviti kakovost družbene infrastrukture izbranih kratkih oskrbnih prehranskih verig v Mestni občini Ljubljana in njen vpliv na varovanje virov, zmanjšanje odpadne hrane in ...embalaže. V raziskavi smo obravnavali šest ponudnikov, vključenih v kratke oskrbne prehranske verige z zabojčki, skupnim naročanjem in partnerskim kmetovanjem. Presoja objektov s pomočjo smernic trajnostne gradnje BNB (Bewertungssystem Nachhaltiges Bauen) je pokazala slabo kakovost in pomanjkljivo družbeno infrastrukturo. V pogovoru z intervjuvanci smo spoznali, da si želijo urejena in lahko dostopna prevzemna mesta z objekti, ki bi omogočali dobre pogoje za ljudi in živila. Mestna občina Ljubljana ima glede na bližnje podeželje z dobrimi pogoji za ekstenzivno in ekološko kmetijsko pridelavo še veliko možnosti za povečanje samooskrbe s kakovostno domačo hrano, ob tem pa bo morala poskrbeti za razvoj družbene infrastrukture.
Maintenance of traditional cultural landscapes largely depends on traditional agricultural practices, which are nowadays in decline as a result of increasingly intensive and mechanised land use. ...Losing traditional practices may result in impoverishing of picturesque mosaic landscape and biodiversity. This research focuses on land-use changes in two time periods (2002–2008; 2013–2016) and effects of changes reflecting on populations of critically endangered butterfly. False Ringlet,
(Lepidoptera: Nymphalidae), is a habitat specialist, which in Slovenia inhabits two geographically distinct contrasting habitats – dry meadows in south-western and wetlands in central Slovenia. We compared nine environmental parameters to assess environmental differences, which shape species habitat; seven parameters significantly differ among the four geographical regions and five among the two habitat types. Four parameters significantly differ (i.e. at least in two regions) when tested for homogeneity, while in dry habitat type all (except slope) were significant and none in wet habitat. Changes in land use in two studied periods lit up two processes: transformation of meadows into agricultural land and overgrowing of the meadows, both processes affecting species severely. We believe that maintaining of traditional landscapes in future could serve as a good conservation practice for this endangered species.
The paper presents the results of the survey conducted among geography students of the three public universities in Slovenia regarding their knowledge of sustainable development and the ways of ...gaining this knowledge. On the basis of 160 questionnaires, distributed mainly among the first-level students, we concluded that the students assess their knowledge of sustainable development as very good. However, they lack knowledge about social aspects of sustainable development. They gained most of their respective knowledge through formal education. The knowledge of sustainable development improves in the course of study years on the first level and particularly on the second level. This fact and the answers regarding connectedness of study programmes with the topic of sustainable development (also the courses mentioned by the students) show that sustainable development is well integrated into geography study programmes.
Abstract
The Balkan Peninsula represents one of the three southern European glacial refugia where biodiversity persisted throughout the climatically unstable Quaternary. This study considered the ...‘refugia within refugia’ model, which assumes the environmental heterogeneity over time and space in larger refugia. To better understand patterns shaped during the Quaternary climatic oscillations, the present and last glacial maximum (LGM) environmental conditions and current morphological variability of Edraianthus tenuifolius, an endemic plant of the western Balkans with a well-known therphical structure, were considered. Potential present and LGM distributions were studied through environmental niche modelling using 161 data of occurrences and six bioclimatic variables, hindcasting the model to LGM conditions using three different global circulation models. To test the geographical variability of the reproductive region, 41 characters of 667 inflorescences from 35 populations within the distribution range were measured. Geographical patterns, using geostatistics together with univariate and multivariate statistical approaches, were analysed. The environmental niche model suggested the current potential distribution in correspondence to its known occurrences. The hindcast to LGM conditions suggested two separate areas of environmental suitability, one in the present-day northern Adriatic coast of Croatia (Istrian Peninsula, Kvarner) and another on the present-day south-eastern Adriatic coast (southern Dalmatia, Montenegro and northern Albania). Morphological variability showed a similar pattern, where southern populations separated from northern populations according to a major split in the central part of its distribution range (central Dalmatia). On other levels, stronger barriers were predicted to separate northern populations from the eastern Istrian Peninsula and the Kvarner area. The results suggested congruent biogeographical patterns to the already known phylogeographical structure. Both environmental niche modelling and the geographical variability of morphological characters suggested spatial partitioning, indicating the potential presence of two separate refugia during the LGM.
Combining occurrence data with present and LGM environmental conditions coupled with spatial analysis of phenotypic plasticity of floral characters the authors reveal once again the intricate biogeographic patterns within the Balkan Peninsula. The endemic plant Edraianthus tenuifolius shows patterns of geographical variation that strongly support the 'refugia within refugia' concept in the South European refugia. Moreover, results from the present work are congruent with a previous phylogeographical study supporting the recognition of refugial areas for thermophytic plant taxa during the glacial events of the Pleistocene.
Slovenian part of the Adriatic Sea is its most northern part which occupies approximately 200 km2 and is a part of the wider Gulf of Trieste. Slovenian coast consists of 47 kilometers of mostly ...steep, abrasive marl and sandstone coast. Low accumulation coast is located only at the mouths of the watercourses and represents but a smaller portion, whereas the smallest part is occupied by the limestone abrasion coast. Mainland coastal region is mostly hillside and has a very diverse relief, while plains, in smaller numbers, are located only in the lower parts of the river valleys. Slovenian sea indents the mainland by two larger gulfs: the Gulf of Koper and of Piran and is predominately very shallow. The average depth is around 18 m and the largest depth is 38 m at the Madona cape near Piran. Sea bottom is mostly covered by the thick layer of sediments deposited after the abrasion of the steep cliff coast and by the accumulation of the river alluvium. Due to its shallowness the sea is exposed to high temperature fluctuations and due to the fresh water influx also to the changes of its salinity.The circulation of the sea water is mainly induced by the tide and wind activities, mostly the Bora (strong north-easterly wind) which significantly influences the vertical circulation of the water. Water current is weak and unstable. There is a large influx of nutrients into the Slovenian sea, resulting from the soil erosion, surface water influx, watercourses and direct emissions of waste waters into the sea. The consequence of the mentioned sea characteristics is a great landscape sensitivity of the coastal sea ecosystem. During summer the sea warms intensely and when accompanied by the weak water circulation, we are often witnessing the lack of oxygen in the deeper layers of the water, intensive algae growth and sea blooming, which points to exceeded self-cleaning (assimilation) capacities of the marine ecosystem.The major polluters are the coastal towns of: Koper, Izola, Piran and Portorož, nautical tourism with marines, naval traffic and the port activity of the Luka Koper. The pressures on the marine ecosystem due to the human activities are still increasing, both on the mainland and in the sea, despite some measures to reduce the pollution. According to the assessment of the Mediterranean action plan (UNEP-MAP), Slovenian coastal sea is, due to its oceanographic characteristics and the economic activities influence, ranked among the most sensitive and endangered parts of the Mediterranean. Environmental state of the Slovenian part of the Adriatic Sea will try to be presented through the DPSIR model or the amended Integral Model of Geographical Study of the Environment and its Components.
