Wood-pastures combines livestock grazing with trees and shrubs. They provide several ecosystem services, including biodiversity, soil protection, carbon storage, water management. However, wood-pastures have been through a sharp decline all over Europe, mainly due to environmentally uncontrolled intensification of agriculture, abandonment and improper management of the land use, which resulted in the loss of the valuable ecosystem services which they provide. In this paper, we investigate the potential of wood-pastures to provide regulating ecosystem services by their ability to prevent or mitigate the soil erosion. The assessment process has been performed by applying the RUSLE model, using GIS. The model has been applied in eight study-polygons, corresponding to four villages situated in the southern Transylvania, Romania. Our results show that wood-pastures have a lower predicted annual soil...

The presence of mining, with all its specific activities carried on for decades, leads to an inevitable change in the evolution of environmental factors. Among these, and especially in the conditions of open-cast mining, the soil is definitely affected. The present study examines the soils developed on mine dumps in Aghireş mining area. It is noted that depending on how the mine dumps were managed, a differentially pedogenesis process started on their surface. Under these conditions, in order to determine the physical characteristics of soils in question, four sampling points were chosen, plus a fifth one with the role of control sample. The final results show clear differences between the physical parameters of investigated soil samples depending on the pedogenesis conditions, differing between the planted dumps and those without a protective vegetation cover.

The presence of the Izvorul Crisului local territorial administrative unit (commune), in the western part of the Transylvanian Depression, not far from its border with the Apuseni Mountains, implies the existence of various natural hazardous processes. Their manifestation, in the presence of anthropic components and their activities and goods, determines their hazard attributes. Of the possible natural hazards (geological, geomorphological, atmospheric, hydrological, biological, etc.), only the geomorphological, hydrological, and meteorological ones will be addressed in this paper. The presence of these natural processes may cause material damage and victims, for this it is necessary to know their magnitude. Thus, the present study aims to identify the potential hazards which exist in the Izvorul Crisului administrative unit and to assess the susceptibility to these natural processes. To achieve this objective, specific maps will be made, which finally, beside the supporting role for the analysis of natural processes, will become tools for the management of these conditions, tools to reduce the induced risks.

The questionnaire survey method is often used in investigating the behaviour, the perception, the knowledge and the attitude of population regarding different environmental issues. In this case, the questionnaire survey method is used in improving waste management process at local level. In Cluj-Napoca, like in other Romanian cities, there is little involvement in waste management process and selective collection of waste at source. This is the issue that the paper is addressing through an online survey questionnaire applied on a sample of 425 persons living in Cluj-Napoca. The questions refer to three main aspects: degree of awareness regarding selective collection of waste at source, the accessibility of the service, and present and future personal behaviour in this sector. The answers reveal that the majority of the respondents are aware ...

The study was conducted in laboratory micro tanks with contaminated water from the municipal landfill water storage pit with toxic bund of Somârd/Medias, Sibiu County, in order to research and develop a bioremediation technology using constructed wetlands. In this research of biomonitoring and bioremediation, Lemna minor, Vallisneria spiralis were used as biological indicators and as useful species in phytoextraction and biological depollution.

Geographically this unit it is positioned on the north-western part of the Transylvanian Basin. For the landslides distribution analysis, we used five criteria: geology, slope, altitude, exposition and the local administrative units. We must have this type of studies, on one hand to find out how the current landslides are distributed, and on the other hand to identify the areas which are prone to this type of hazardous geomorphological phenomena. By investigating the study area’s ortophotoplans and topographic maps, 1892 landslides were vectorized to create a landslide inventory map. The study shows that lithologic conditions (the presence of friable rocks such as marls, clays, sand) and the land use (mostly agricultural lands) are the most defining factors for landslide to develop, it is believed that in the future landslides will appear on similar slope, orientation and geol...

To achieve this goal, several field trips were organized during which observations on the area were noted and biological samples were collected (soil samples). The study was based also on laboratory and computer studies during which biological samples were analyzed and the results were processed to determine the degree of impact. The current study focused primarily on assessing the quality of the terrestrial biotic environments, by identifying the main groups of invertebrates and plant species that inhabit the anthropogenic soils and on the recent observations made on field in the affected area. The results of some preliminary studies on the stability of the waste dumps and on the quality of the aquatic biotic environments were also considered. Based on all information gathered this way, a rapid impact assessment m...

The mentioned regional unit is placed geographically on the central part of the Transylvanian Basin (large depression area placed in the interior of Carpathian Mountains). In order to analyse the distribution of the landslides we took into consideration 5 criteria: geology, altitude, slope, exposition and the administrative units. This type of study is necessary on one hand to find out the way in which the current landslides are distributed, on the other hand, the research will collect information on the susceptible areas which are prone to this type of geomorphological processes. Following the analysis of the ortophotoplans and topographic maps a number of 4.109 landslides were vectorised. Considering the land use landslides are found mainly on agricultural lands. Taking into consideration the lithologic conditions (the presence of friable rocks such as marns, clays, marl clay) and the l...

A key challenge is the integration of the social demands for green spaces with the maintenance of key ecosystem structures and processes as well as the biodiversity of the green spaces. In this study, we report our experience and insights gathered through the implementation of a project targeting a peri-urban forest development near the city of Cluj-Napoca. One key particularity of the project was that it was designed by the city hall in cooperation with a major NGO, and the academic sector joined the project in its second stage, with the aim of mainstreaming ecosystem services and biodiversity within a well-established design concept. After comprehensively assessing the biodiversity and ecosystem services of the targeted forest, we found that the ecosystem supply was strongly related to the tree stand structure and the forestry management ...

A special attention is generally needed for the wood pastures which combine livestock grazing with trees and shrubs. In this paper, we investigated the differencess between the wood pastures and tree-less pastures and their role to prevent or mitigate the soil erosion. The soil erosion assessment has been performed by using of RUSLE and GIS. The model has been applied in two study-polygons with wood pasture and tree-less pasture located in the northern part of Hartibaciului Tableland (Romania). Our outcomes showed and highlighted by comparison that wood pastures have a lower predicted annual soil loss than pastures with accidental presence of trees. This fact suggests that wood pastures are more resilient to soil erosion than tree-less pasture. The metholology tried to calibrate a preliminary model of soil erosion assessment for wood pastures into the southern part of Transylvania.
