Responsible Tourism and Tourism Ecology
Abstract: Many efforts have already been made and several ideas have been promoted to solve the problems in the development of socially and economically underprivileged, peripheral areas. Most of the proposals suggest supporting rural tourism and its management based on local natural, cultural, agrarian etc. traditions and help them this way to catch up with the more developed regions of the country. According to our surveys, it can be stated that sustainable and responsible rural tourism development is unbelievable without the application of ecological thinking. Consequently tourism ecology, as theory and practice, naturally helps developing the tourism of rural areas based on local natural, social, and cultural resources. Sustenance of tourism is a double task: we have to provide long-term reservation and guarantee that entrepreneurs’ input of capital will return and their firm’s will better their economic etc. state in the same time. Sustainable tourism has to be endurable and economically executable on long term, but at the same time, it has to be socially and ethically fair in relations to local people. Nevertheless, it is also an expectation that actors of the system, i.e. tourists must continue an active and responsibly sustainable practice (responsible sustainable tourism).

The Semiautomated Identification of the Planation Surfaces on the Basis of the Digital Terrain Model. Case Study: The Mehedinti Mountains (Southern Carpathians)
Abstract: The paper presents a method for the semiautomated classification of the planation surfaces, using the Digital Terrain Model (DTM) and the object-oriented analysis. The effort undergone for developing such a method has a number of motivations. The first one is that these landforms are very important for decoding the geomorphologic evolution of the relief units. The second motivation concerns the fact that their identification and mapping, by using classical means, represents a difficult demarche, which requires a lot of time. Finally, the already-known limits of the relief analysis using the DTM at pixel level impose the testing of an object-oriented analysis, in which the area under study is divided into objects of various dimensions, as homogenous as possible from the viewpoint of one or more properties. The method that we propose supposes the following steps: the realisation of the slope model and of the flow model, starting from the DTM; the division, by segmentation into objects that are as homogenous as possible from the viewpoint of the slope; the classification of the objects into landforms (planation surfaces) by using the fuzzy functions and taking into account more factors simultaneously (the average slope value, the minimum slope value, the flow coefficient and the altitude), and the selection and grouping of the identified surfaces into sculptural complexes. The first stages represent the automated part of the method, while the last one requires a detailed geomorphologic analysis of the area, as well as the validation of the results on the field. The method was firstly developed for the Godeanu Mountains, the map of the levelled surfaces (Niculescu, 1965) being used for the identification of the parameters included in the algorithm, as well as for testing the results obtained in the view of the improvement of the method. Due to the good results thus obtained, the same method was also used for mapping the levelled surfaces in the Mehedinţi Mountains, and, along with the field observations, there was realised the planation surfaces map for this relief unit.

Coastal Environmental Changes Along the North Western Coast of Egypt Case Study from Alexandria to El Alamein Coast
Abstract: The present paper aims at highlighting the urban development, fishing activities, tourism, industrial development and agricultural activities that affect delicate and valuable coastal ecosystems. A supervised classification, post-classification, change detection techniques were applied to Land sat images acquired in 1991 and 2007, respectively, to map land cover changes along the north-western coast of Egypt, from Alexandria to El Alamein. A supervised classification was carried out on the six reflective bands for the two images individually with the aid of true ground data. The truthful ground information, collected during field trips using ancillary data, visual interpretation and experts’ knowledge of the area using GIS, further refined the classification results. Post-classification change detection technique was used to produce image through cross-tabulation. Changes among different land cover classes were assessed. During the study period, a very severe land cover change has taken place as a result of agricultural and tourist development projects. These shoreline and land cover changes led to modifications of the environmental properties.

The Present-Day Erosional Processes in the Alpine Level of the Bucegi Mountains – Southern Carpathians
Abstract: A relief that is strongly modelled by extensive erosion processes (sheet erosion, rills and gullies) characterizes the Alpine level of the Bucegi Mountains. All processes are favoured by the geological structure represented by conglomerates, limestone with grit stone intrusions, by strongly degraded podzolic soils with a loamy-sandy texture in the first layer and by some economic activities, such as the overgrazing and the tourism. We have identified an area with large-scale erosion forms in the sector comprised between Furnica Peak and Piatra Arsa Peak. This paper analyses the genesis and the manifestation conditions of the erosion processes, as well as the climate, making use of the temperature and the precipitation data provided by the meteorological stations in the region. Using the Péltier diagram, we framed the region to various seasons. By subsequently using the Péguy diagram, we framed the region to the morphoclimatic conditions and to the river processes. On the other hand, by using GIS, we created geology, slope, soil and vegetation Boolean maps and then the risk map to the erosion processes.
Keywords: Bucegi Mountains, present-day erosional processes, sheet erosion, rills, gullies, boolean maps, alpine level, Southern Carpathians

Inventoring and Evaluation of Geomorphosites in the Bucegi Mountains
Abstract: Geomorphosites stand for relief forms or geomorphologic processes that in time have gained an aesthetic, scientific, cultural, historical or economic value, as a result of human perception. Taking into consideration the above mentioned definition, the present paper aims at inventorying and evaluating part of the geomorphosites in the Bucegi Mountains. The final purpose is to propose some measures for a better protection and tourist promotion. The presence of numerous geomorphosites in the Bucegi Mountains is the direct result of the presence of limestones and conglomerates, as well as the succession of different modelling systems in time (glacial, periglacial, fluvial). We analysed this area since there are many and varied geomorphosites, and at the same time, it is one of the major tourist destinations (the largest number of tourists and the best tourist infrastructure within the Romanian Carpathian Mountains).
