Tourism evaluation of IBA areas in the Serbian part of Banat

Abstract: On the territory of the Serbian part of Banat there are registered 9 internationally important bird habitats (Importan bird areas-IBA), which are an important resource of bio diversity, but also a significant market potential that can be marketed through tourism. The paper is based on Hilary du Cros model evaluation and analyses the tourism sector and management of IBA sites, investigating to what extent they are attractive to activate the tourism industry. In this way, we established utility value of IBA habitats with emphasis on qualitative and quantitative characteristics of subindicators.

Agroclimatic conditions in Oltenia during the spring of 2011

Abstract: The paper analyses the climatic and agroclimatic conditions during the spring of 2011. Although the climatic global warming process continues, in some years, the climatic evolutions are atypical in Oltenia as well as in the entire country, and, consequently, the spring of 2011 was cold and droughty. Compared to the last 12 springs, the thermal regime indicates that the spring of 2011 was unique, and the pluviometric regime that it was droughty, although the agricultural crops were not affected due to the lower thermal regime that maintained a satisfactory degree of the soil humidity. The late spring hoarfrosts on 7 and 8 May have also had damaging effects in Oltenia. In consequence, there were some stagnation periods for the agricultural crops, and some important delays for the vegetables crops, and there were significant damages in the places where the seedlings were removed in the field. As a consequence of the thermal variations, there have been some diseases and pests, especially Monilinia laxa in stone fruits. Although the periods of weather cooling are considered beneficial to the climate general evolution on the planet, if they appear in the late spring, they represent an important climatic risk factor. Thus, their forecast is welcome especially for the agriculture. This paper is useful for the Ph.D. and master graduates and to all the researchers in the climate and agroclimate field.

Patterns of winter tourism activity in the Bucegi Mountains – the Prahova Valley (the Southern Carpathians)

Abstract: The Bucegi Mountains and the Prahova Valley represent the most important destinations for winter tourism activities, of great heritage value in the Southern Carpathians – Romanian Carpathians. A number of resorts have developed here over time, currently enjoying great popularity among those keen on such activities. This article aims at presenting, on the one hand, the natural features (terrain factors and climate variables) favourable for winter tourism activities, and on the other, our results concerning the statistical analysis of the accommodation infrastructure, ski amenities and tourist flow. The expansion of the ski area and the development perspectives of the existing infrastructure as much as the local, regional and national authorities’ interest represent the premises for hosting the winter edition of the European Youth Olympic Festival, in 2013 and the Winter Olympic Games in the year 2020 in the outlined area.

Torrentiality – Morphohydrographical conditions in the Sebeş Basin (The Parâng Mountains Group, Southern Carpathians)

Abstract: This paper presents the morpho-hydrographical characteristics that define the torrential system inside the Sebeş basin (the Parâng Mountains). The manifestation of torrential erosion takes place on river basins of different sizes. In order to bring out the quantitative and qualitative differences in the stream discharge structure, we resorted to the determination of some geomorphometrical indices such as: the number of river segments, the frequency of elementary thalwegs, incipient or total torrentiality. The great density of the temporary valleys network, along with the emphasized slope of the ditches and flanks generate a high instability. The local differentiations of the geological sublayers and the complementarity of the use of the Cindrel, Lotru and Şureanu mountain areas generate its own answer forms on the aggressive action of the torrential rainfalls on elementary segments with temporary functionality, as well as on permanent hydrographic thoroughfares. The tributary streams received by the Sebeş River in the Carpathian sector have small hydrographic basins and they do not exceed rank 4 in the Horton-Strahler classification system. Torrentiality is stimulated by the combined effect of snowmelt and spring rains, but mostly by the aggressiveness of the torrential summer rains, which take over a modified geomorphological background through excessive depasturage, deforestation and hydropower harnessing. The streams and the floods, through the accumulation of high volumes and energies, produce slope damages, riverbed shifts, blockages and the destruction of communications infrastructure, and material loss.

The periods with pluviometric surplus from the Timiş hydrographical basin (1965-2009)

Abstract: The present study is based on the statistical processing of values, referring to the average monthly and average annual precipitations, for the period 1965-2009. The data was taken from six meteorological stations, five of which are located in the hydrographical basin of the Timiş river, and one station is located in the immediate proximity of this basin. The calculation formula used for the identification of the periods with pluviometric surplus, from the entire period and for all analysed meteorological stations, was the Standardised Precipitation Anomaly – SPA. According to the SPA values and their distribution during the analysed period, within the basin, the degree of vulnerability may be determined for the Timiş hydrographical basin compared to the climatic risk, induced by the precipitation surplus, and, thus, compared to the risk induced by the extreme hydrological phenomena, like floods, which are especially of a pluvial origin.
