GIS analysis of an area representative for the Romanian hardly accessible mountain regions with a complex and high-valued touristic potential
The crucial importance of mountain regions in the socioeconomic and environmental cohesion policies is underlined by key documents in Romania as well as in the European Union. However, the lack of a unique definition or set of criteria used to delineate the mountain regions, in order to analyze their characteristics constitutes a barrier to the elaboration of a common strategy for their development. This study has created a methodology based upon

Potential effects of climate change include loss of biodiversity and ecodiversity due to direct influences and habitat changes and impacts on agricultural systems resulting into the decrease of productivity. While direct assessment is rarely possible, the evaluation methodology focused on statistical modelling. This study used the Geographical Information Systems to look at the spatial distribution of 2100 predicted temperatures in Romania by landform

The present paper presents significant changes occurred in the multi-annual dynamics of zooplankton diversity and abundance (1980-2007), under the pressure of human-induced eutrophication in two shallow lakes specific for the Danube Delta. Zooplankton community from lakes Matita and Merhei was characterized by high species richness but low abundance values until 1981, in ecological conditions unaffected by eutrophication. For the next ten years,

Based on July land surface temperature (LST) in the Romanian Carpathians derived from MODIS (Moderate Resolution Imaging Spectroradiometer) images, this paper investigates the vertical thermal lapse and the influence of several factors. The astronomical parameters, atmospheric circulation and geographical factors are relatively similar in the area of interest, so that the influence of elevation, aspect, and land cover becomes more relevant at regional

In the broader context of the importance granted to accessibility by the European spatial planning policies, comparing the effi ciency of European and national transportation routes and corridors constitutes an issue of particular relevance for Romania. In order to resolve it, this paper proposes a methodology based on potential accessibility, determined by the total population served, and the effi ciency of the path, by analogy with the least squares
Read moreSystemic theory applied to ecology, geography and spatial planning. Theoretical and methodological developments
Starting from a critical comparative analysis of how the systemic conception is applied in geography, ecology and spatial planning, with a particular focus on the new concept of 'territorial system', the book demonstrates the hypothesis according to which the transfer of statistical methods currently used to study ecological systems toward the analysis of territorial systems is not only possible, but also beneficial based on theoretical foundations

The extensive use of the Geographical Information Systems, but also of their extensions, in fields that do not necessary connect to geography, but allow for the implementation of methodologies based on the analysis of spatially referenced data, had resulted into new applications and methodological approaches to answer specific research questions. This paper proposes such an extension from the real space define by longitude and latitude to a virtual

In 1999 Romania became part of the Bologna process, focused on the European Credit Transfer and Accumulation System, design to increase the compatibility of European universities, ensuring the mobility of students and professors in the context of re-orienting education to the formation of competences continuously adapted to market requirements. This model draws the new education system closer to American education. The paper analyzes the importance

Clime change represents an important issue for the scientific community regardless of the specific field of study due to the environmental effects and impacts on the economy (especially agriculture) and human communities. The environmental impacts include the loss of biodiversity (species and ecosystems), while agricultural impacts include the exposure to heat, changes of the precipitation regime, and dispersion of diseases and pests. The assessment
