“…On the other hand, the specific load caused by a single vehicle decreases if the road quality is better and if detours are not necessary to reach certain areas. Forests are also endangered, but the primary threat to forests is not tourists, but rather inadequate forest management [87]. Another threat related to tourism is the appearance of businesses interested only in maximising their profit.…”

Empirical Investigation of the Motivation and Perception of Tourists Visiting the Apuseni Nature Park (Romania) and the Relationship of Tourism and Natural Resources

As part of an international project, national parks and nature parks established in karst regions are examined, with a primary focus on how local residents, visitors and influential figures (i.e., park managers, mayors) perceive the advantages and disadvantages of a specific park. The study area in this paper is the Apuseni Nature Park (Romania). The main natural resources of this park are: the karst (morphology and hydrology), the forests and the landscape. In order to explore the perception and motivation of tourists visiting the park, a field survey using a convenience sampling strategy was conducted in 2019 and 2021 at eleven sites in the park. The results show that among the motivations, the “search for relaxation” option is the most frequently selected (43%), but “interest in caves” (34%) and “interest in karst terrains” (29%) were also relatively popular. In terms of public support for potential developments, one positive result of the questionnaire is that developments involving sustainability and nature conservation (visitor centre, education trails and viewpoints) enjoy significantly more support than developments that put a strain on the environment (adventure parks and expansion of entertainment facilities). The awareness of geotourism should be improved, but even at the current level it can be said that geotourists are an important segment of the park’s visitors. A careful development of tourism can be recommended for the park, but it must ensure that the principles of sustainability are taken into account during the developments. Given the environmental and economic challenges, strengthening the organization of the park is suggested in order to better protect the threatened natural resources.

“…Previous studies underlined the utility of these methods due to the possibilities to use the raster and vector-type databases, to analyse the correlations established between the factors and to provide a quantitative model regarding the opportunities to use a certain species for afforestation, taking into account the restrictions and favourability induced by the environmental factors (Păcurar et al, 2013;Roșca et al, 2017;Roșca et al, 2019). The GIS technology is used both for the favourability study and for monitoring changes in forest vegetation (Lacaze et al, 1996;Rørstad et al, 2010;Furtună, 2017).…”

“…The monitoring of changes in terms of land use and implicitly the expansion or reduction of forested areas may be indirectly performed on the basis of spatial analysis models which involve remote sensing techniques by means of integrated analyses of spectral bands within satellite images (Furtună, 2017;Mândru et al, 2018;Furtuna, 2017;Roșca et al, 2019). Monitoring may also be directly performed by analysing the pre-processed spatial data provided by different monitoring agencies (European Environment Agency, Forestry Departments, the Agricultural Payment and Intervention Agency etc.…”

A very simple analysis of the forested areas across the Transylvanian Basin shows that they cover approximately 45.8% of the area, according to data provided by the European Environment Agency. In order to extend the areas covered by forests, especially over badlands specific for the Transylvanian Basin and to increase the economic and environmental value of these lands, a GIS model of spatial analysis has been developed to identify the areas favourable for downy oak (Quercus pubescens) plantations, a forest species which has specific requirements in terms of adaptability conditions. The developed spatial analysis model is based on the unitary analysis of the climatic, soil and geomorphologic components, spatially materialized as raster format databases, and their integration according to spatial analysis equations in order to get a modelled database which represents spatially the favourable areas for the creation of downy oak plantations. The result of this study highlights the territories which provide favourable but also restrictive conditions for Quercus pubescens. The model has a high predictability rate taking as comparative reference the direct monitoring at the level of forest planning units (PUs) within Cluj County, identified from the analysis of forestry plans. The high validation rate of the proposed model was obtained by overlapping the favourability classes which themselves were obtained after modelling with the limits of the forest planning units where the consistency of the downy oak is greater than 0.7. According to the presented validation procedure, a 93% validation rate was obtained, fact which highlights the usefulness of applying the model in areas having similar features and its extrapolation in areas where the environmental conditions present only slight differences. ********* In press - Online First.

“…Landsat is one of the oldest missions which has the advantage of releasing many images free of charge for any type of users. Landsat scenes are often used for various types of analysis: tracking forest changes (Furtuna et al, 2016, Furtuna, 2017, detection of areas affected by storms (Furtuna et al, 2018;), detection of the old scattered windthrows (Haidu et al, 2019).…”

The Land Surface Temperature Evolution (Lst) Using Landsat Scenes. Case Study: The Industrial Platform Săvineşti

During the communism, the accent of development was put mainly on industry. This is also the case of The Industrial Platform Săvineşti, from Neamţ county, which assured two major productions: textile fibers and chemical fertilizers. After the fall of the regime, the platform was divised and some of the new owners have sold all the equipments, have demolished the buildings, leaving the place barren. In the present, only a few of the old factories still work, and new stakeholders started their businesses. The study aims to show how the land surface temperature (LST) evolved in association with the events that followed from the flowering period of the factory. Three summer months from different years (1991, 2008 and 2018) where taken into consideration and LST was calculated based on Landsat scenes from missions 5-TM and 8-OLI. In order to make the whole process faster, two models were constructed using ArcMap extesion Model Builder. Besides the land surface temperature, there were calculated another two indices: Normalized Difference Vegetation Index (NDVI) and Normalized Difference Moisture Index (NDMI), which offer additional arguments to the changes that took place on the platform. The purpose of the study is to show how land surface temperature changes depending on the use of the territory, thus the importance of remote sensing being emphasised.
