Geoparks in SE Poland as Areas of Tourism Development: Current State and Future Prospects

: Geoparks currently form the basis for the development of geotourism and, therefore, proposals of new geoparks are developed in many countries, including Poland, where over 20 locations for geoparks have been proposed so far. Two national geoparks have been established thus far, while another two have received the status of UNESCO Global Geoparks None of them are located in the Carpathian Mountains. Simultaneously south-eastern Poland—the Podkarpackie Province—boasts valuable geoheritage, biotic and cultural assets. In the past, having regard for the geological heritage, several research teams proposed the creation of three geoparks encompassing the existing landscape parks in that area. However, these were proposals based solely on scientiﬁc values. The objective of the study was to comprehensively assess their tourism potential, with a particular focus on geoheritage assets. The assessment has made it possible to determine to what extent these assets meet the conditions necessary for the functioning of this type of areas, i.e., the occurrence of diverse tourist assets, well-developed infrastructure and appropriate development potential. The assessment method used is based on 25 indices forming six groups. The analyses have been carried out for districts lying within the proposed geoparks. It has been found that the analysed area has a sufﬁciently high geoheritage potential that can be the basis for the functioning of two geoparks. The tourist infrastructure—particularly accommodation and catering facilities and geotourist trails—needs to be expanded and improved. It is particularly important to encourage local communities to become involved and engage in business activity within the geopark.


Introduction
The idea of creating geoparks is relatively recent, as this year marks the 20th anniversary of the European Geoparks Network, but the number of geoparks around the world has been growing quite dynamically [1][2][3][4].Topics related to geoparks are also more and more frequently taken up by researchers, e.g., [5][6][7][8] and many others.At present there are 161 geoparks in 44 countries around the world, with the highest number being in China (41) and Spain (15) [9].Geoparks are functional areas for the promotion of geoheritage, development of tourism (geotourism) and education accompanied by sustainable social and economic development [10][11][12][13][14][15].According to a definition proposed by UNESCO, a geopark is a unified area with geological heritage of international significance.Geoparks are not new forms of nature protection as they are usually established based on the already existing forms, e.g., national parks or landscape parks [5,6].A necessary condition for their creation and proper functioning are bottom-up activities resulting from the involvement of the local community in the preservation of the geoheritage assets and the development of tourist facilities [16,17].In 2015, as a result of decisions made at the International UNESCO Conference in Paris, UNESCO global geoparks were given a very high rank, comparable to the list of World Heritage Sites and Biosphere Reserves.It should be stressed that it is also possible to create regional or national geoparks whose establishment is regulated by laws applicable in specific countries [5,18].At present, geoparks are the basis for the development of geotourism, i.e., "a knowledge-based tourism, an interdisciplinary integration of the tourism industry with conservation and interpretation of abiotic nature attributes, besides considering related cultural issues, within the geosites for the general public]" [2].
Thus far, three areas in Poland have been awarded a national geopark certificate, namely the Muskau Arch Landscape Park (2009), St. Anne Mountain (2010) and the Karkonosze National Park with its buffer zone (2010) [19].The first one has now the rank of a UNESCO Global Geopark, while the Holy Cross Mountains Geopark was also added to the network in 2021.It should be stressed, however, that the legal status of geoparks in Poland is undefined: there are no formal grounds for the functioning and management of geoparks.The area of national geoparks partially overlaps with the area of a national park (Karkonosze Mountains Geopark) or a nature reserve (St.Anne's Mountain Geopark).The lack of legal grounds is an impediment to the establishment of geoparks.The protection of geoheritage assets in Poland is based on the protection of areas and sites in the form of national parks, nature reserves and natural monuments.More or less advanced geopark studies or proposals have been prepared for other areas.In most cases, apart from more or less advanced conceptual works conducted by scientists, arrangements with local governments or local organisations have not been made yet.Their interest and involvement are indispensable for the establishment and functioning of a geopark [17].
South-eastern Poland (particularly the Bieszczady Mountains) has above-average natural and cultural assets on the European scale [18].This potential can be used for tourist and educational purposes [6].The occurrence of unique natural and cultural assets in the southern part of Podkarpackie Province has given grounds to propose three areas with geopark status: the Flysch Carpathians Geopark, the geopark in the Bieszczady Wysokie Mountains and the Wisłok Valley-the Polish Texas Geopark [6,[20][21][22].Their borders have been delineated based on the existing forms of nature protection-landscape parksareas whose environmental, historical, cultural and landscape assets are protected and popularised according to the principles of sustainable development.This is based on the premise that, owing to the lack of formal grounds for geoparks, they may be established based on landscape parks in the first stage [5,20], particularly given that the goals of geoparks and landscape parks partially overlap.
Geosites are key elements from the perspective of the development of geotourism and education, while inventorying and evaluating them is the first step towards establishing a geopark [23][24][25][26].According to Reynard (2004) [27], "geosites are defined as portions of the geosphere that present a particular importance for the comprehension of Earth history, geological or geomorphological objects that have acquired a scientific, cultural/historical, aesthetic and/or social/economic value due to human perception or exploitation".In the case of Poland, geosite data are available in Poland's Central Register of Geosites that currently contains over 3000 sites [28].
Valuable geoheritage assets are the primary basis for the establishment of geoparks [29].However, geoparks are more likely to be created if attractions related to geoheritage and human culture occur in a particular area.This presents an opportunity for the creation of a complementary offer for tourists.Examples of such areas include the already functioning Global Geoparks in Austria (Ore of the Alps, Styrian Eisenwurzen), Belgium (Famenne-Ardenne) or Croatia (Papuk) [9].The establishment of a geopark is consistent with the international concept of the four Es of tourism (education, entertainment, excitement and engagement).Geoparks are created particularly for informed tourists who stay in such areas and intend to explore the local assets based on their knowledge while respecting nature and cultural heritage.Apart from specific assets, the existence of appropriate tourist infrastructure and geotourist products is indispensable for the creation of a geopark.Deficiencies with regard to such products are particularly visible in the case of Poland [30,31].
The study objective was to assess to what extent the initial concept for the creation of geoparks in the southern part of Podkarpackie Province is grounded in assets of the natural and cultural environment and the existing tourist infrastructure.As a result, it will be possible to answer the question whether the planned geoparks are merely concepts developed by scientists or whether there is a chance for these plans to become reality.Although the study is concerned with a specific area, a method has been proposed for a comprehensive assessment of the tourist assets of an area, with particular focus on geoheritage features.The main premises of the proposed method can also be used in other areas and can be the basis for assessing the feasibility of creating geoparks.At the same time, special attention has been paid to the obstacles to the development of geoparks; these obstacles may occur in other countries as well.

Study Area
The potential geoparks are located in south-eastern Poland, in the Podkarpackie Province (Figures 1 and 2).They encompass urban, urban-rural and rural districts (46 in total) within which the potential geoparks are located.The idea of creating geoparks in these areas appeared at the turn of the 21st century.The first one to be proposed was the Flysch Carpathians Geopark [20] that would be located within several existing landscape parks: Cisna-Wetlina Landscape Park, Jaśliska Landscape Park, Czarnorzeki-Strzy żów Landscape Park, Słonne Mountains Landscape Park and Przemyskie Foothills Landscape Park (Figure 2).The next proposal was the Geopark in the High Bieszczady [21] that would cover a smaller area but its area would be more cohesive, with homogeneous natural assets.It would comprise only two landscape parks-the Cisna-Wetlina LP and San Valley LP-forming the buffer zone of the Bieszczady National Park.The third one is the Wisłok Valley-the Polish Texas Geopark [22,32].It would also partially overlap with two landscape parks (Jaśliska LP and Czarnorzeki-Strzy żów LP) and the Magura National Park (Figure 2).The borders of the landscape parks were delineated according to natural environment criteria, and they do not coincide with the boundaries of administrative units.Therefore, the study has encompassed the entire districts located within the existing landscape parks and the potential geoparks.

Geoheritage
The natural environment of areas designated as the potential geoparks is diverse, particularly from a geological and geomorphological perspective.The southern part of the province is located in the Outer Carpathians (referred to as the Flysch Carpathians).They have complex geological structure and tectonics, which makes them attractive from the perspective of geotourism.They are mainly composed of flysch formations that were developed from marine sediments in a vast synclinal sedimentary basin, starting from the Upper Cretaceous (Jurassic) until the Palaeogene (Lower Miocene).These are complexes of alternating beds of conglomerates, sandstone, mudstone and claystone.These sediments are accompanied by secondary carbonate and silica rocks.As a result of tectonic movements in the Miocene, the flysch rocks were detached from their base and transported from the south to the north where they were thrust on each other, forming nappes-the main tectonic units of the Carpathians.The following nappes occur within the study area: the Magura Nappe, the Dukla Nappe, the Silesian Nappe, the Subsilesian Nappe, the Skole Nappe and the Stebnica Nappe in the Rzeszów-Przemyśl region.In the north, in the zone bordering the Pre-Carpathian Depression, the flysch is overlain by patches of Miocene formations that, at the contact with the Skole unit, were folded with the Carpathian flysch, forming the Zgłobice Nappe (Figure 1) [33].The land relief in the Flysch Carpathians is directly determined by the geological structure.Its basic elements are systems of ranges of foothills and mountains with flattened tops, divided by basins and valleys formed by tectonic movements as well as by erosion and denudation.A system of parallel, narrow ridges and steep valleys form a peculiar kind of relief that corresponds to the arrangement of the steep folds of the nappes [35].The relative elevations of the individual mountain ranges increase towards the south.Starkel (1972) [36] distinguished the following basic types of relief in this area: relief of valley and basin floors, relief of the foothills and low-and medium-mountain relief.The relief developed in several stages-from the Neogene, Pleistocene and Holocene-up to the recent anthropogenic changes.
The area is located almost entirely in the Vistula basin within the Baltic Sea drainage basin, with only a small fragment in the Dniester basin within the Black Sea drainage basin.It is drained by the river systems of the Wisłok, San and Strwiąż [35].The geomorphological activity of rivers led to the development of characteristic landscapes of deeply incised valleys and gaps.Such a landscape with a dense river network offers very favourable conditions for the development of tourism and recreation.It is further aided by the presence of numerous protected areas (parks, reserves and natural monuments).The land relief in the Flysch Carpathians is directly determined by the geological structure.Its basic elements are systems of ranges of foothills and mountains with flattened tops, divided by basins and valleys formed by tectonic movements as well as by erosion and denudation.A system of parallel, narrow ridges and steep valleys form a peculiar kind of relief that corresponds to the arrangement of the steep folds of the nappes [35].The relative elevations of the individual mountain ranges increase towards the south.Starkel (1972) [36] distinguished the following basic types of relief in this area: relief of valley and basin floors, relief of the foothills and low-and medium-mountain relief.The relief developed in several stages-from the Neogene, Pleistocene and Holocene-up to the recent anthropogenic changes.

Forms of Nature Conservation
The diversity of the natural environment components in the southern part of the Podkarpackie Province, particularly the geological structure and land relief, determines the existence of valuable natural and landscape assets (Figures 1 and 2).All legal forms of nature conservation, established pursuant to the Act on Nature Conservation [38], occur here.The most valuable areas are within two national parks-the Bieszczady National Park (established in 1973) and the Magura National Park (established in 1995)-with particularly valuable abiotic environments.Flora and fauna habitats are protected within

The diversity of the natural environment components in the southern part of the Podkarpackie Province, particularly the geological structure and land relief, determines the existence of valuable natural and landscape assets (Figures 1 and 2).All legal forms of nature conservation, established pursuant to the Act on Nature Conservation [38], occur here.The most valuable areas are within two national parks-the Bieszczady National Park (established in 1973) and the Magura National Park (established in 1995)-with particularly valuable abiotic environments.Flora and fauna habitats are protected within Natura 2000 areas.
The Bieszczady National Park (districts of Czarna, Ustrzyki Dolne and Lutowiska) encompassing the Bieszczady Wysokie range, lies within two tectonic units: primarily the Silesian Nappe and, in the south-eastern part, the Dukla Nappe (Figure 2).The parallel arrangement of SE-NW-trending ridges is a characteristic feature of the land relief, directly linked to the lithology and basement tectonics.The slopes are dissected by deep valleys of streams [39].Crude oil was exploited within the boundaries of the Bieszczady National Park, and oil and gas seepage currently occur there [40].Since 1992, the Bieszczady National Park, along with the Cisna-Wetlina Landscape Park and the San Valley Landscape Park, has been part of the East Carpathians Transboundary Biosphere Reserve (Poland/Slovakia/Ukraine) [41].
The Magura National Park (districts of Dukla and Krempna) is located in the Beskid Niski Mountains (Figure 2).In terms of geology, the Park lies in the outer zone of the Magura Nappe composed of formations that are highly disrupted tectonically.They are composed of thick-bedded Magura sandstones, separated by variegated shale and Inoceramus beds.The Magura sandstone outcrops occur as numerous rock forms (crags).The headwater area of the Wisłoka catchment lies within the park's boundaries [42].
Within the study area, there are six inanimate nature reserves and nine landscape reserves of high abiotic value (Table 1).The former kind primarily consists of rock clusters, as well as an area of rock rubble and lakes formed by the blocking of a valley by a landslide.In the landscape reserves with valuable abiotic assets, mainly the gap valleys of rivers and parts of slopes featuring rocky outcrops are protected.
The most valuable tree specimens or forms of inanimate nature (e.g., waterfalls, rocks) are protected as natural monuments (a total of 27).They primarily include crags (complexes of rock forms), rocky outcrops, cascades, waterfalls, springs and a cave.A particularly high concentration of natural monuments can be found in the Korczyna district (crags, springs, a waterfall).Most of them are of natural origin, but some of them are a result of human activity, mainly the quarrying of rocks, e.g., the Lesko Stone or the Rocky Wall in Krywe [43].
Documentation sites (form of nature protection in Poland) have been established in some of the geological sites.A total of 26 such sites have been identified in the nine districts covered by the present study.These are mainly natural geological outcrops exposing diverse rocks, including flysch, and land relief features (e.g., residual hills of denudation origin, landslides, parts of river valleys, cascades) as well as typically anthropogenic outcrops such as quarry walls or underground quarries.With as many as 10 documentation sites, the district of Fredropol stands out in this respect [44].A total of 259 geosites can also be found in the area, among them the most valuable inanimate nature sites representing various forms of geodiversity and documenting the geological history and geological processes, e.g., individual outcrops and clusters of outcrops of natural and anthropogenic origin; erratics; landforms formed by accumulation and denudation; sites with interesting minerals or rocks, water sites; traces of mining activity; interesting landscape forms, etc.-significant for science, culture and history (Figure 3).The geosites have not been formally marked in the places where they occur; they have only been recorded in Poland's Central Register of Geosites.They partially overlap with the above-mentioned forms of nature conservation.Most of them are situated in the districts of Korczyna and Niebylec, while the greatest typological diversity occurs in the districts of Baligród, Dukla and Korczyna.Two hundred and twenty-three caves occur in the Carpathian flysch.Most of them are small caves up to a few metres long.The largest caves are located in the Dukla district (in the "Osuwiska w Lipnicy" Natura 2000 area): Jaskinia Słowia ńska-Drwali (601 m long and over 23 m deep), Gangusiowa Jama (190 m long and over 11 m deep), Lodowa Szczelina (166 m long and 10.5 m deep).

Cultural Heritage
Over the centuries, the study area has been in the ethnic, political and religious borderland.Such a location has resulted in the development of cultural heritage, preserved in many places until today and distinguished by great diversity arising from the multiethnic and multi-denominational past (Figure 4).An outline of the settlement network in the Carpathians crystallised in the Middle Ages (mainly in the 14th century), after a series of incorporations under German law.From the 15th century, settlements were established under Wallachian law.Among the population, involved in animal herding, two ethnic areas evolved: the Lemkos in the east and the Boykos in the west.From the mid-19th century, the region developed economically, with the construction of railways and dynamic development of the oil industry, among other aspects.Tourism and health resorts also started to develop in the second half of the 19th century.During the First World War, the Carpathians saw some long-lasting military operations which left numerous military cemeteries in their wake.More tragic events occurred during the Second World War (extermination of the Jewish population), while the post-war years saw the expulsion of the Greek Catholic and Orthodox population [46].
In the second half of the 19th century, a new spatial complex-a spa-appeared in the Carpathians, modelled after European spas.The Carpathian spa is characterised by wooden architecture, loosely drawing on Tyrolean and Swiss models.The basic compositional element is the natural therapy complex with the accompanying layout of diverse vegetation [47].Two old spas-Iwonicz Zdrój and Rymanów Zdrój-and a new health resort in Pola ńczyk operate in the Beskid Niski Mountains (Figure 2).The health resorts are adjacent to areas with valuable natural assets, protected under law, which additionally increases their value for tourism.Mineral waters are a significant resource of the potential geoparks "The Flysch Carpathians" and "The Wisłok Valley -The Polish Texas" [32,48].
Pursuant to the Act on the Protection and Care of Historic Monuments (JoL No. 2020 item 282) [49], immovable historic monuments are protected under the following forms: entry in the register of monuments, recognition as a monument of history, establishment of a cultural park or determination of the scope of protection in planning documents (Art.7).Within the study area, there are 1148 sites entered in the register of monuments: from 2 sites in the Solina district to 243 sites in the city of Przemyśl.They are diverse in terms of their functions as they include religious complexes of various denominations, palaces and manor houses, public buildings, residential buildings, industrial facilities, etc.They also include sites of particular significance for cultural heritage, i.e., four monuments of history (mine in Bóbrka, castle complex in Krasiczyn, Old Town complex in Przemyśl and the Przemyśl fortress) and one cultural park (Old Town Hill in Krosno).

Tourist Development
The valuable natural assets and cultural heritage of the area are definitely of tourist interest.The landscape parks within the study area vary a lot in terms of tourist development.It should be remembered that adequate infrastructure not only makes a given area accessible, but it also enables the volume of tourist traffic to be controlled so as not to exceed the resilience of the natural environment [52].The accommodation infrastructure-the basic determinant of the possibilities of developing the tourist function-is

Tourist Development
The valuable natural assets and cultural heritage of the area are definitely of tourist interest.The landscape parks within the study area vary a lot in terms of tourist development.It should be remembered that adequate infrastructure not only makes a given area accessible, but it also enables the volume of tourist traffic to be controlled so as not to exceed the resilience of the natural environment [52].The accommodation infrastructure-the basic determinant of the possibilities of developing the tourist function-is quite varied in the study area.It comprises 20,515 beds (Statistics Poland, data for 2019) [53].The accommodation infrastructure is most developed in districts linked to the Cisna-Wetlina Landscape Park and the San Valley Landscape Park (districts of Ustrzyki Dolne-1900 beds, 120,604 total overnight stays provided; Cisna-1426 beds, 58,744 total overnight stays; Lutowiska-1407 beds, 64,991 total overnight stays).The structure of the accommodation facilities is dominated by private lodgings (guest rooms and agritourist lodgings), while holiday centres are of smaller importance.Hotels are located primarily in towns.Health resort districts are at the top with regard to the number of beds.The spa infrastructure is located in Iwonicz-Zdrój (7 facilities and 909 beds), Rymanów-Zdrój (5 facilities and 479 beds) and Pola ńczyk (5 facilities and 908 beds).The development of the catering infrastructure is determined by the development level of the accommodation infrastructure and intensity of tourist traffic.Bistros and small food outlets predominate.Establishments offering traditional cuisine are developing gradually.
In the case of areas (primarily non-urbanised), the statistical data on the number of beds and overnight stays provided are highly underestimated.Studies by Zawili ńska (2010) [54], conducted in districts administratively linked with the Carpathian landscape parks, indicate a significant underestimation of the number of beds in the official records of Statistics Poland [55] (number of beds according to Statistics Poland vs. number of beds according to Zawili ńska [54]): Jaśliska LP: 2293 vs. 587; Cisna-Wetlina LP: 9634 vs. 4062; San Valley LP: 7683 vs. 3229; Słonne Mountains LP: 3726 vs. 1714; Czarnorzeki-Strzy żów LP: 558 vs. 99; Pogórze Przemyskie LP: 1265 vs. 604.These statistics do not include data on guest rooms and beds in agritourist farms or guests staying at non-registered lodgings, e.g., at campsites, with friends or in second homes.
Numerous tourist trails (walking, cycling, horse-riding and car trails) have been designated thanks to the cultural and historical heritage, the tangible traces of the region's multi-cultural past, natural environment assets and valuable landscapes.Cultural trails are among the most interesting ones: the Wooden Architecture Trail, the Hasidic Route, the Route of the Lubomirski Family Estates, the Trail of Historical Houses and Gardens, the Wallachian Culture Trail, the Trail of the Carpathian Shrines, the Military Cemetery Trail, the Blue San Trail, the Papal Trail or the Icons Trail.The Petroleum Trail links places associated with the exploitation of crude oil (Figure 4).
The Wooden Architecture Trail comprises wooden historic buildings that have had a whole range of different functions: religious buildings (Catholic, Orthodox and Uniate churches, belfries, parsonages), public buildings, industrial facilities (flour mills, windmills, smithies, sawmills), manor houses, complexes of small town and rural architecture, health resort architecture.Buildings and historic monuments of tangible folk culture have been collected in the Rural Architecture Museum in Sanok [56].
The most important industrial heritage site in the study area is the oldest crude oil mine in Bóbrka; crude oil deposits occur in the Cię żkowice sandstone.The year 1853, when Ignacy Łukasiewicz and Jan Zeh distilled and refined crude oil and when kerosene lamps were introduced in a hospital in Lviv, is regarded as the beginning of the petroleum industry in Poland.As early as 1854, a crude oil mine was opened in Bóbrka near Krosno.The mine has survived military operations and political changes.In the 1950s, a new oilfield was discovered and has been exploited until today.In 1961, the Ignacy Łukasiewicz Skansen-Museum of the Oil and Gas Industry was established at the mine.Two original oil wells from the 19th century have been preserved there [57,58].

Methods
Assets significant from the perspective of tourism development were assessed using common methods for multi-criteria assessment [59][60][61][62][63]. Six groups of criteria were distinguished: (i) geoheritage assets-geodiversity (5 criteria); (ii) biotic environment assets (3 criteria); (iii) cultural heritage assets (5 criteria); (iv) the potential of tourist attractiveness (4 criteria); (v) the potential of tourist infrastructure (4 criteria); (vi) the potential for devel-opment (4 criteria).Analyses were carried out for 46 districts located within the potential geoparks.The assessment rules and criteria are presented in Table 2, while the sources of data are shown in Table 3.
Table 2.The rules of assessing the tourism potential of districts.LP, Jaśliska LP and Czarnorzeki-Strzy żów LP are situated within the boundaries of these districts (Figure 5A).

Potential
have a varied potential of geoheritage (Figure 4).Six districts were assigned to category V and VI, while 16 districts have a low potential (category I).In spatial terms, districts with the highest potential are located in the southern and western part of the Podkarpackie Province (the Polish Texas and Bieszczady Wysokie geoparks).The San River Valley LP, Cisna-Wetlina LP, Jaśliska LP and Czarnorzeki-Strzyżów LP are situated within the boundaries of these districts (Figure 5A).

Potential of Animate Nature
Animate nature reserves occur in 10 districts, including four districts that have 2-4 reserves each.Animate nature monuments have been found in all but two districts.On average, there are 22 monument per district, with the maximum being 121.The proportion of areas included in the Natura 2000 network varies a lot and ranges from 0 to 99% of the district area; it is 33% on average.The potential of animate nature, determined based on the occurrence of conservation forms of high rank, is not very high in the districts under study: 17 have been assigned to the lowest category, while only eight to categories IV to VI. Districts with the highest potential in this respect are located in the north-eastern part of the province (Figure 5B).

Cultural Potential
Sites included in the UNESCO World Heritage List occur in four of the districts under study.Each of them features historic monuments, but of course most sites are located in districts with larger towns such as Przemyśl, Krosno or Sanok (from 50 to 243 sites).In a few districts, no more than five historic monuments occur per district.There are various kinds of historic monuments: 35 districts have over 10 types of monuments each, e.g., tserkvas, churches, cemeteries, palaces, manor houses, public buildings, burghers' houses, etc. Cultural trails have been designated in 25 districts, and cultural events take place in nearly all districts.On the other hand, cultural parks and monuments of history occur in just a few districts.The districts under study have a moderate level of cultural potential, with only six of them belonging to categories with the highest potential (V-VI).
Districts with high and medium potential are distributed quite evenly across the entire province (Figure 5C).

Potential of Tourist Attractiveness
This kind of potential comprises elements that have not been assigned to the first two groups.It shows strong links to the environmental characteristics of the area.The southern part of the province, with higher, often tree-covered mountain ranges and a greater density of the river network, has a clearly higher potential with particularly attractive landscapes.The highest potential occurs in areas where it is additionally enhanced by the occurrence of unique tourist attractions-Przemyśl, Sanok, Dynów-and cultural events (Figure 5D).The differences in this potential among the districts under study are not very big, with 35 districts assigned to category II, III and IV.

Potential of Tourist Infrastructure
The number of accommodation places in the districts under study varies quite considerably, ranging from 0.1 to 35 per 1 km 2 .It is similar in the case of overnight stays provided: this parameter ranges from 2 to 6000 per 1 km 2 .This number is the highest in towns and health resorts.The density of the road network shows smaller variation, from 0.2 to 1 km per 1 km 2 , and the density of bike paths varies the least: from 0.2 to 1.2 km per km 2 .Ten districts have been assigned to category I of the potential, and seven districts to category V and VI.Districts with the highest potential in this respect are located in the central part of the province (Figure 5E).

Development Potential
According to the adopted methodological framework, the districts under study have quite a good development potential.Nineteen districts belong to the top three categories, and only one district to the lowest category.However, on average, only 14% of the area of the districts is covered by local spatial development plans.On average, the registered unemployed account for 7% of the working age population, while the average revenue of the district budget amounts to PLN 5400 per one inhabitant.The highest development potential occurs in the western part of the province (Figure 5F).
To carry out a comprehensive assessment of the potential of the districts under study, a two-dimensional matrix was prepared based on geodiversity potential and additional values (Figure 6).The largest cluster of districts has low potentials (18 districts in categories I and II); another twelve districts belong to a cluster with medium or high potential (categories III to VI).According to the adopted methodological framework, high potential (categories V and VI) of the main and additional values does not occur in any of the districts under study (Figure 6).
unemployed account for 7% of the working age population, while the ave the district budget amounts to PLN 5400 per one inhabitant.The highes potential occurs in the western part of the province (Figure 5F).
To carry out a comprehensive assessment of the potential of the study, a two-dimensional matrix was prepared based on geodiversity po ditional values (Figure 6).The largest cluster of districts has low potential categories I and II); another twelve districts belong to a cluster with medi tential (categories III to VI).According to the adopted methodological fr potential (categories V and VI) of the main and additional values does not the districts under study (Figure 6).The clustering of districts based on the results of the assessment h identification of four clusters (Table 4, Figure 7) where the following sets tics (potentials) occur: The method used has indicated districts with high geodiversity pot levels of other kinds of potential-Iwonicz-Zdrój, Lesko, Solina, Dukla, Fr as districts with high geodiversity potential and moderate/low levels of potential-Dubiecko, Korczyna.The clustering of districts based on the results of the assessment has enabled the identification of four clusters (Table 4, Figure 7) where the following sets of characteristics (potentials) occur: The method used has indicated districts with high geodiversity potential and high levels of other kinds of potential-Iwonicz-Zdrój, Lesko, Solina, Dukla, Frysztak-as well as districts with high geodiversity potential and moderate/low levels of other kinds of potential-Dubiecko, Korczyna.

The tourist attractiveness of a specific area consists of natural environment and cultural assets, tourist development and transport accessibility.A significant factor is the tourism policies conducted at different levels of government in a given country, including policies related to the organisation of the tourism management system and support of its development, including financial support.Owing to the cultural and natural heritage and landscape values, the area of the Carpathians in the Podkarparckie Province is indicated in national and regional strategy and planning documents as predisposed to the development of leisure and tourism [64,65].Since no geopark has been established in the Polish Carpathians yet, the tourist asset assessments thus far have been conducted within landscape parks.
Warszyńska and her team (1980) [66] conducted a tourist attractiveness assessment for the natural environment assets of the Carpathian landscape parks.Taking into account the mean values of indicators for localities administratively linked to landscape parks, she assessed the tourist attractiveness of the individual parks.Among the parks that could become geoparks, the Cisna-Wetlina Landscape Park and the San Valley Landscape Park have been assigned the highest category in the general attractiveness category (Table 5).A high general tourist attractiveness is indicative of favourable conditions for tourism throughout the year, and thus the possibility of developing tourism as the main or equivalent function [67].

Zawili ńska (2010) [54] used the SWOT analysis to assess the possibilities for the development of tourism in the landscape parks of the Carpathians.Based on that analysis and the assessment of the tourist potential of the natural environment and cultural assets, as well as the level of tourism infrastructure development, she distinguished models of tourism and identified the possibilities and directions of the sustainable development of tourism.In total, she distinguished seven types of landscape parks, according to the characteristics of the tourist function, and formulated four development models for them.In the area of the landscape parks that were indicated as potential geoparks in the Podkarpackie Province, she distinguished three types and two development models (Table 6).Although the abiotic potential was not the subject of a separate assessment, the specific directions of development are universal and can be pursued based on tourist products prepared within the geoparks.
The above assessments of districts administratively linked with landscape parks show that the area analysed has a significant tourist potential.Tourism in landscape parks takes advantage of a variety of tourist assets.At the same time, its development hinges on transport accessibility along with the development of tourist infrastructure that will enable pursuit of a given form of tourism.In areas with valuable natural environment assets, the development of mass tourism is not recommended because this form of tourism leads to intensive land development and considerable motor vehicle traffic.In such cases, sightseeing tourism, particularly forms relying on the unique assets of a given area, and ecotourism are preferred.The results of studies by various authors [54,66,67] indicate a very high tourist attractiveness of districts in the Cisna-Wetlina LP and San Valley LP.In their case, the primacy of nature conservation should determine the development of tourism.The tourist function is of enormous significance for the economy of these areas.The situation is similar in the case of the districts of the Jaśliska LP, Słonne Mountains LP and Pogórze Przemyskie LP, where low tourist capacity is accompanied by average tourist assets.The tourist assets in the districts of the Czarnorzeki-Strzy żów LP received the lowest rating.At the same time, these areas show valuable abiotic assets that have justified proposals for establishing geoparks [20][21][22].

Prospects for the Establishment of Geoparks
Geoparks may play a very significant role in the development of tourism in a given area and may thus foster regional development [68,69].Therefore, efforts to establish geoparks are undertaken in many areas.However, a given area must meet specific criteria in order to become a geopark.In the case of the European Geoparks Network, the criteria are as follows [70]: (1) A geopark is an area that comprises unique geological heritage and has a strategy of sustainable territorial development.It must have clearly defined boundaries and sufficient areas allowing real territorial economic development.
(2) It must consist of a specific number of geological sites of special significance in terms of scientific value, rarity, aesthetic value or educational value.Most sites located within a geopark must be part of the geological heritage, but they may also be of an archaeological, ecological, historical or cultural nature.(3) A geopark plays an active role in the economic growth of its area by improving the overall image based on geological heritage and development of geotourism.(4) A European geopark has a direct impact on its territory, influencing the living conditions and environment of its inhabitants.Its establishment should be aimed at enabling residents to take advantage of the economic potential offered by the local geoheritage, and to actively manage the entire territory.
In the case of Global Geoparks, the assessment is carried out according to the following criteria: Geology and Landscape; Geoconservation (25%); Natural and Cultural Heritage (10%); Management Structure (25%); Interpretation and Environmental education (15%); Geotourism (15%); Sustainable Regional Economic Development (10%).(https://en.unesco.org/global-geoparksaccessed on 6 September 2021).In the case of the potential geoparks, the condition related to the occurrence of valuable geological and geomorphological heritage assets is met.Inanimate nature reserves, inanimate natural monument and geosites occur in the area of the potential geoparks.However, they are not evenly distributed.The situation is similar in the case of cultural and natural heritage.The lack of formal regulations concerning the establishment of geoparks and their functioning in the administration structure is a very serious challenge.Alongside the UNESCO geoparks and two national geoparks existing in Poland, over 25 areas have been initially proposed as potential geoparks in the future [6].Some of the geoparks, e.g., the Małopolska Vistula Gap or the Stone Forest in Roztocze, have detailed scientific documentation, while in the case of other geoparks, the development of documentation is clearly less advanced [71].Unfortunately, the work stops at this stage in most cases.There is a lack of institutional support for local governments, which definitely makes it difficult to create structures for the management of geoparks.Therefore, it is particularly important to prepare regional development strategies that would take into account the possibility of establishing geoparks [72,73].Thus far, studies on the directions of tourism development in the Podkarpackie Province have been conducted in districts located within landscape parks.The development of tourism and education exclusively based on geological and geomorphological assets can be difficult, at least in the initial stage.Therefore, it would seem advisable to develop tourism based on all the assets occurring in the area, with a particular focus on the geoheritage, before proceeding with any possible efforts to establish geoparks.
Based on the results of the assessment of potentials, with a particular focus on geoheritage, and the results of clustering, it should be assumed that the geopark in the Bieszczady Wysokie Mountains and the Wisłok Valley-the Polish Texas Geopark are the best proposals that are the most likely to work.In both cases, the abiotic assets are very valuable.A SWOT analysis has been carried out for districts administratively linked with the potential geoparks (Tables 7 and 8).Factors in the following categories have been considered: geoheritage, animate nature, cultural resources, tourism development and socio-economic situation.The internal determinants (strengths and weaknesses) include an assessment of the current situation in the districts, while the external determinants (opportunities and threats) represent the existing external factors and those that may arise in the future (also within a district).The supplementary resources used consist of the following: scientific monographs and articles, statistical data obtained from Statistics Poland 55 and indicators calculated on their basis, strategy and planning studies, spatial data, websites and field surveys.The SWOT analysis has enabled broader strategic inferencing and indicated the directions of the sustainable development of tourism.According to the SWOT analysis for geoheritage and biotic and cultural resources for the districts within which the two proposed geoparks would be located, the strengths have a significant advantage over the weaknesses.The existing opportunities may strengthen these advantages and contribute to the development of the region.On the other hand, tourist development, and the socioeconomic determinants in particular, has a much weaker position, and it is necessary to take advantage of the existing opportunities and, above all, to mitigate the weaknesses and avoid the threats.
In the Bieszczady Wysokie Mountains, the natural environment assets are more valuable, which is confirmed by the fact that the most valuable areas are covered by the highest form of legal protection, i.e., national park.It is also an area of international rank-the East Carpathians Transboundary Biosphere Reserve.Therefore, further development of the accommodation and catering infrastructure should be planned very carefully so that it does not have a negative impact on the natural environment and landscape.The development of geotourism is most appropriate here.Alongside geomorphological processes and hydrologic phenomena, traces of oil exploitation can also be observed.This peripheral area has a deficient technical infrastructure and major socio-economic problems.
In the Wisłok Valley, on the other hand, in addition to the abiotic assets-numerous rock forms, rocky outcrops and hydrologic phenomena-it is possible to observe oil exploitation facilities and remnants of oil processing facilities.The area is unique on a global scale.However, it requires very extensive marketing actions and the preparation of tourist infrastructure for various groups of visitors.The tourist traffic has been small to date, there is a lack of accommodation, catering and accompanying infrastructure.The poor promotion of the assets and tourist attractions in the immediate vicinity is also a serious problem.The location and resources of the area provide a basis for preparing a very diverse offer, including geotourism.According to clustering, the Frysztak district emerges as an area with a high level of geotourism potential and other kinds of potential, hence this district should be included in the geopark.
The establishment of the Turnica National Park would be an important impulse for the development of geotourism in the Podkarpackie Province.Efforts for its establishment have been undertaken for 35 years.The park would be located within the Wiar river catchment (districts of Ustrzyki Dolne, Fredropol, Bircza).As Kotlarczyk observes (2018, p. 92) [74], "The exceptional value of the area arises from its geological position and geographical location, morphology, geological structure and history of inanimate nature processes, and zones of minimum transformations of the original crust surface as well as from the diverse landscape of high aesthetic value."The area features many outcrops where geological phenomena unique on the scale of the Carpathians can be observed: interesting stratotypes, rich macrofauna sites, rocks of organic, chemical and diagenetic origin, diverse forms of sedimentation in an oceanic basin.The establishment of such a park would certainly stimulate tourist traffic in the Pogórze Przemyskie Landscape Park and San Valley Landscape Park located on either side.It would also make it possible to prepare an extensive tourist offer for different target groups.An area with high abiotic environment assets that would consist of a mosaic of three national parks with five landscape parks would undoubtedly enable the preparation of geotourist products of diverse aesthetic, scientific and educational value.Such a network of areas with different conservation regimes, encompassing sites of diverse value and origin, could function very well.The preparation of a geotourist offer adapted to the individual potential and assets in the proposed geoparks in the Bieszczady Wysokie Mountains and the Wisłok Valley-the Polish Texas, taking into account the limitations in use and the need to protect inanimate and animate nature, offers the possibility of designating zones with the tourist function.At the same time, it makes it possible to achieve the goal of establishing a geopark i.e., sustainable socio-economic development.Perhaps in the future, after the new national park is established, extending the Bieszczady Geopark to include the Słonne Mountains Landscape Park should be considered.Institutional support for the districts within which the geoparks would operate should be another step.Local government, tourism-related businesses and residents need to get involved.The local community should be convinced about the need to establish the geopark and about the potential benefits from it.Then, the community should be actively involved in the preparation of the master plan and its implementation.As the history of the establishment of geoparks in Poland shows, the most difficult stage is setting up a robust association of districts that carries out successive tasks and stimulates sustainable economic development.It seems that the biggest challenges are the lack of formal regulations (legal provisions, methodology guides) and financial support.As examples of Local Action Groups show, the cooperation between districts-also based on the tourism potential of a given area-can be fruitful.The experience of such Local Action Groups should be used when organising geoparks.Several such groups operate in the study area, e.g., "Kraina Nafty" ("Land of Oil") or "Zielone Bieszczady" ("The Green Bieszczady").
Persuading the local community to get involved in the process of establishing geoparks and then their operation is a major task.Residents have to be made aware that the "geopark" brand can help develop the tourist function and thus mitigate the unfavourable socio-economic phenomena occurring in the area.Demographic problems, particularly depopulation resulting from the negative migration rate and an ageing population, are of fundamental importance.The highest population density occurs in the districts of the Czarnorzeki-Strzy żów LP, while it is significantly lower in the other districts, which results from the resettlements in the past (Operation Vistula).In the peripheral rural districts, there is a high proportion of registered unemployed in the working age population; it is the highest in the districts of Cisna (14.1%),Solina (13.1%), and the lowest in the district of Rymanów (1.9%) [55].The lack of jobs is linked to the small number of businesses operating in the area.Owing to the socio-economic situation and the low efficacy of local governments in attracting investors, districts have low levels of revenue.
The districts within the landscape parks under study have to resolve various conflicts of the functions, needs of local communities and economic development.Investment projects implemented in the inhabited space not only improve the quality of life for the local community, but also contribute to enhancing the attractiveness of localities (regeneration of public space, improvement of the quality of health resort space, development of infrastructure related to environmental protection and improvement of transport links).At the same time, the proportion of areas with residential housing and service establishments has been allowed to increase in many districts, which has intensified the suburbanisation processes and led to the deterioration of the landscape assets.When preparing new areas for the development of business operations which are not always neutral to the condition of the natural environment, it is absolutely essential to consider the environmental determinants.The fundamental planning instrument enabling the appropriate management of space, including tourist space, is the local spatial development plan which specifies the rules for the spatial development and functions of a given area.It also provides the basis for safeguarding spatial order.In cases in which a local plan does not exist, the so-called decisions on development conditions and land management are issued for a specific area, or sometimes even for individual plots, but they do not ensure sufficient protection of space [75].Among the districts under study, only two-Dukla and Krościenko Wy żne-are fully covered by local plans, while in the case another two-Jaśliska and Krosno-just over half of their territory is covered.In 59% of the districts, less than 5% of their territory is covered by local plans [55].This indicates a very high threat to the spatial order, landscape and nature, particularly in the context of strong pressure of the development of single-family housing and tourist infrastructure.The main threat to the area is the propagation of various kinds of residential and tourist housing, including summer houses, service establishments and health resort treatment facilities, accompanied by the expansion of the access road network.While this increases the accessibility of the area, it can contribute to the development of mass-scale tourism in areas with valuable natural assets.Sustainable development in the districts, safeguarding the environmental balance and mitigating conflicts and preservation of the spatial order are possible only when spatial policy is conducted properly.

Conclusions
The analysed area has a sufficiently high geodiversity potential that can be the basis for the development of geoparks.The existing potential of geoheritage gives grounds for the establishment of two geoparks: a geopark in the Bieszczady Wysokie Mountains and the Wisłok Valley-the Polish Texas Geopark.
It is advisable to expand protected areas and extend protection over subsequent natural environment and cultural heritage sites.
The tourist infrastructure, primarily accommodation and catering facilities and geotourist trails need to be modernised, expanded and improved, but these measures should take into account the need to protect the natural environment.
It is indispensable to prepare legal regulations and rules of institutional and financial support in order to determine the operating framework of geoparks.It is also crucial to prepare local communities so that they become actively involved and undertake business activity within the geopark.
