Abstract. The crucial importance of mountain regions for the cohesion policies is underlined by key Romanian and European Union documents. However, the lack of a unique definition or criteria used to delineate and analyze them constitutes a barrier to the elaboration of development strategies. This study has created Geographical Information Systems-based methodology to select Romanian hardly accessible mountain regions with a complex and high-valued touristic potential and determine their characteristics using spatial analysis based on specific indicators. The results indicate that mountain regions are affected by poor accessibility, resulting into the lack of basic Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential supplies, as well as education and health issues. Tourism trends suggest reduced accommodation, food, and entertainment opportunities, increased number of tourists, but decreasing average durations of stay and usage of touristic facilities. Based on these findings, the outstanding touristic potential of Romanian mountain regions appears to be insufficiently valorized, calling for actions on behalf of the authorities. JEL classification codes L5, L8, N7 Keywords: GIS; mountain region; tourism; regional development; accessibility Background Among the goals of the European Union related to territorial cohesion, mountain regions represent a priority (European Commission, 2001). Furthermore, the proposed European Constitution shows that mountain regions, in conjunction with territorial and socioeconomic cohesion, are crucial objectives of European regional development (The European Convention, 2003). Most regional European policies address mountain regions; 95% of these areas receive funds either for development or socioeconomic conversion (Popescu, 2008). The interests of mountain regions are promoted in the EU by cooperative association (e.g., EUROMONTANA), networks of multisectoral professional organisms, and some INTERREG programs (e.g, Interreg IIIB: Carpathian Project, Parks&Economy, Ruraltour, Shining Mountains, Development of a Sustainable Tourism or the Alpine Space Programme). The mountain regions received special interest also due to their vulnerability to environmental threats due to their special characteristics: inclusion of fragile ecosystems, harsh climate, isolation, political and economic isolation, etc. (United Nations, 1992). The sustainable development of these regions had been agreed by the adoption of the Convention on the protection and sustainable development of the Carpathians in Kyiv, 2003. In Romania, mountain regions differ from other regions due to natural disadvantages (i.e., elevation, clime, slope, low soil fertility, reduced access to the communication routes and markets), and structural disadvantages (i.e., ageing active population, migration trends, restricted jobs, distances from decisional centers, and insufficiently developed infrastructure) (Government of Romania, 2003). The Romanian Government aims to align the trends of tourism with the regional and international goals, i.e., to increase the circulation, diversify the offers, and increase the quality of services; another goal is to develop spatial development policies contributing to socioeconomic 79 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential cohesion of administrative units and regions, increased competitiveness, and the conservation of natural and cultural diversity (Government of Romania, 2004). In order to implement these goals, specific instruments aim to develop sustainable tourism, based on in-depth knowledge of the ecosystems and environmental carrying capacity with respect to tourism, and identify areas with a complex and high-valued touristic potential (Ministry of Regional Development and Housing, 2008). The identification of mountain regions is based on their definition. However, this is not unique, as different documents propose a variety of criteria, synthesized in Table 1 below. [Table 1] Definition of mountain regions in different documents. The table indicates the definition and its interpretation, as well as the source. Definition Source Areas characterized by limited possibilities of using the land and high costs of European works due to: (a) the existence of different climate conditions, i.e, at elevations Council, 1999 2 over 600-800 m; (b) presence of steep slopes, i.e, with a gradient of 1-5 per km ; or (c) any combination of (a) and (b). Physical, environmental, socioeconomic and cultural region where disadvantages Euromontana, derived from elevation and other natural factors must be accounted for in 2004 conjunction with socioeconomic constraints, and spatial and environmental imbalance. Climate analysis should consider the latitude and geographical position in addition to elevation. Physical aspects must include the landform, soil type, and other factors in addition to the slope. Socioeconomic disadvantages include the low density of population, isolation due to large distances from cities and other economic and political centers, and the dependence on agriculture. Elevation, slope and the environmental gradients generated are key components Blyth et al., of mountain regions, but their combination is problematic; elevation alone 2002 excludes old and low mountains, and includes high elevation areas with little landform and environmental variation. The following classes are proposed: (a) elevation between 300-1000 m and elevation variation over 300 m; (b) elevation between 1000-1500 m and slope over 50 or elevation variation over 300 m; (c) elevation between 1500-2500 m and slope over 20; (d) elevation between 25003500 m; (e) elevation between 3500-4500 m; and (f) elevation over 4500 m. 80 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential The Euromountains project resumed precedent definition, but used in addition an index of temperature contrast equal to 0.25. The project included only North-European areas, high elevation areas, areas with a very diverse topography, or with extreme climate conditions, as well as any possible combinations (Price, 2007). In the south-eastern Europe, the definitions of the mountain region (Table 2) are mainly based on elevation, occasionally on other criteria (Backmeroff et al., 1997; Price, 2000; Buttoud, 2001). [Table 2] Definition of mountain regions by country. Minimum Country elevation Other criteria (m) Bulgaria The Czech Republic 600 700 Poland 350 Romania 700 Slovakia 600 Slovenia 600 Albania 650 Croatia 650 Norway 600 Former Yugoslavia Elevation between 300-350 m with slope over 15% Elevation below 600 m if over half of agricultural parcels have slopes over 25% 500 The availability of modern technologies has made possible a more precise and consistent characterization of European mountain regions. Among them, Geographical Information Systems (GIS) represent decision support systems involving the integration of spatially referenced data in a problem solving environment (Cowen, 1988). A 2000 study used information from the GTOPO30 database, produced by the United States Geological Survey in 1996 in conjunction with the Geographical Information Systems (GIS) to develop two new criteria: (a) the slope, computed based 81 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential on a raster using the values of the eight adjacent cells, and (b) the local elevation range (LER), again computed in a raster based on the minimum and maximum elevation and their difference at a certain distance from each cell. The two criteria resulted into a new definition: a level difference over 300 m within a 7 km radius from considered milestone. The application of this definition had produced a new classification of mountain regions, including: (a) regions with elevations over 2500 m (oxygen threshold; also, all ecosystems are characteristic to mountain regions); (b) regions with elevations between 1500-2499 m and slopes over 2˚ (prevents high elevation fields and plateaus from inclusion); (c) regions with elevations between 1000-1499 m with slope over 5˚ or LER > 300 m (slope introduced to prevent plateaus from inclusion); and (d) regions with elevations between 300-999 m and LER > 300 m (Blyth et al., 2002). This study will create a methodology utilizing the GIS technology in conjunction with other software to identify Romanian hardly accessible mountain regions with a complex and high-valued touristic potential and underline, through spatial analyses, their characteristics. The result may be used by decision factors to develop special policies in line with the European and international strategies providing for a sustainable development of these regions, and will contribute to the knowledge of the status of mountain regions at the level of the European continent. Methods This study defined mountain regions as territories situated at high elevation, with a diverse topography (even though at low elevation), or with extreme climate conditions (even though either at low altitude or without a diverse topography), as well as any possible combination. Areas were not included if their total surface was less than 5 km2. Administrative units were selected if over 50% of their territory overlapped mountain regions. 82 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential [Fig. 1] Selection of areas situated at elevations over 600 m in Romania (dark gray) The identification of mountain regions was a process involving the following steps: 1. The selection of areas situated at elevations over 600 m, according to the Romanian Law of the Mountain (Parliament of Romania, 2004), was based on the Digital Elevation Model (DEM) of the terrain using ArcGIG 9.2. This step also involved the transformation of the raster file into the shape (.shp) format using the 3-D Analyst. The final selection represented the mountain region (Fig. 1). 2. The ArcGIS selection of the administrative units that intersect the mountain region defined in step 1 and cities situated at distances of 60 km or less from it (Fig. 2). 83 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential [Fig. 2] Selection of the administrative units that intersect the mountain region in Romania. Dark gray symbolizes the mountain region, light gray is used for administrative units with elevations over 600 m, white is used for administrative units with elevations below 600 m (plain and hill areas), while black indicates cities situated at distances of 60 km or less from the mountain region. 3. The identification of territories situated at high elevation was based on the selection of one of the following three criteria: (a) administrative units with elevation over 600 m (1045), (b) administrative units with elevation over 800 m (701), and (c) administrative units with elevation over 1000 m (532). Based on other studies, the second criterion was preferred. The 701 units constituting the mountain region represent approximately 22.1% of all administrative units in Romania, and out of these 89 (12.7%) are urban (Fig. 3). 84 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential [Fig. 3] Administrative units situated within the mountain region (elevations over 800 m) in Romania (dark gray). [Fig. 4] Administrative units situated within the mountain region with a complex and high-valued touristic potential in Romania. 4. The assessment of the touristic potential of administrative units was based upon the criteria presented in Table 3. Based upon the scores, administrative units were given a status reflecting the 85 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential touristic potential of their resources: very high (over 25 points), good (20-25 points), fair (14-20 points), and low (less than 25 points). The end result of this stage was the selection of 426 units (Fig. 4). [Table 3] Criteria and scores used to rank the touristic potential of Romanian administrative units within the mountain region.

The identification of hardly accessible administrative units with a complex and high-valued touristic potential required a spatial definition of hard access. In our study, the hardly accessible units were those accessible only via local (county or communal) routes, and those situated at large distance from the closest representative centers and accessible via national routes in a precarious technical condition. This step involved a ranking of access from high to low: (a) European highway; 86 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential (b) main national highway; (c) secondary national highway, county or communal highway for units situated in the hill or mountain region; (d) lower rank highway and position in a cul-de-sac; (e) low rank highway and large distance from higher rank routes. At the end, 162 units (32.3% of all units situated at high elevations) were selected (Fig. 5). [Fig. 5] Hardly accessible administrative units situated within the mountain region with a complex and high-valued touristic potential in Romania. 6. The final selection of hardly accessible administrative units situated at elevations over 800 m with a complex and high-valued touristic potential was based on the grouping in clusters of at least three units from those identified in stage 5. This stage excluded singular isolated units, even though meeting all criteria specified below. The rationale consisted of the fact that a regional policy can be applied only to a large and compact area. As a result, 16 hardly accessible mountain regions with a complex and high-valued touristic potential, including 131 units (out of which seven are cities), were selected (Fig. 6). 7. The construction of the database of hardly accessible mountain regions with a complex and highvalued touristic potential followed the algorithm displayed in Fig. 7. The selected Database Management System was Visual FoxPRO 8, compatible with ArcView GIS 3.2 used for spatial analyses. The database contained data on the indices presented in Table 4, provided by specialized 87 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential agencies: physical data were derived from scanned topographic maps; other data were provided by the Tourism Research Institute, National Institute of Statistics, and other specialized agencies. Further computations were performed using Excel and Visual FoxPRO 8. The values were checked for errors. In a next step, the database was imported into GIS. Final additional verifications were performed for some units, based on the result of analyses using specific indices, compared to other ongoing or past results. GIS analyses were based on assessments performed using the values of indices to establish rankings of the administrative units.

The results underlined a series of common characteristics that diminish the changes of exploiting the touristic potential of all identified regions: (a) The quality and development of roads are insufficient; many units do not have direct road access and/or cannot utilize them during the rainy seasons. This situation affects negatively the economy and exchanges. 90 Oana Cătălina Popescu, Alexandru-Ionuţ Petrisor, GIS Analysis of Romanian Hardly Accessible Mountain Regions with a Complex and High-Valued Touristic Potential (b) Most households utilize well for water supplies, wood, oil, or coal stoves for heating and have limited Internet access. (c) Education has a low quality due to the infrastructure and lack of qualified personnel. This situation also affects the quality of the work force. Most young people from these areas abandon education due to poverty, lack of transportation and poor motivation originating from the income that education could bring. (d) Access to medical services represents a serious issue, with particular focus on the ageing population, requiring special care.

Fig. 8 and 9 display the distribution of the density of accommodation units, respectively food and dining units, while Fig. 10 shows the distribution of the total number of both accommodation and food and dining units in hardly accessible administrative areas situated within the mountain region with a complex and highvalued touristic potential in Romania. Tourism trends suggest reduced accommodation, food, and entertainment opportunities, an increase in the number of tourists, but a decrease of the average duration of stay, and reduced usage of the touristic facilities. The limitations of the analyses have been due to the availability of data for some of the indices. Additional data would strengthen the relevance of the findings. However, the results are consisted with other studies developed in the same area.
