Floating Away : The Impact of Hydroelectric Power Stations on Tourists ’ Experience in Iceland

It is of vital importance that nature-based tourist destinations maintain their natural resources in a sustainable way. Nature and wilderness are the main attractions for tourism in Iceland. The Central Highlands are uninhabited with little visible evidence of human influence except for some huts, gravel roads, and a small number of hydroelectric power plants. However, there are plans for further hydroelectric power development in the area. The Blanda Power Station was constructed in 1991 at the edge of the North Central Highlands. This paper presents the results of a questionnaire survey conducted among tourists in the area in the summer of 2016 with a total of 1078 answered questionnaires. The objective was to estimate the impact of the power station on the experience of tourists and to assess whether their attitude differs from that of tourists in locations where power plant construction has been proposed. The results show that the power plant infrastructure at Blanda, with the exception of transmission lines, does not seem to disturb the experience of the majority of tourists. Tourists at Blanda are also more positive towards power plants than at locations where there are no power plants but where they have been proposed.


Introduction
Given that hydroelectricity is a renewable source of energy which is as an important driver for climate change mitigation (e.g., Klöpper [1]), the acceptance of hydroelectric power in societies is generally high.However, hydroelectric power plants have an unavoidable impact on the landscape, reflecting Nadaï and Horst [2], (p.143) observation, "There can be very little doubt that energy will remain the number one driver for landscape transformation in the 21st century".As a result of demands for low carbon energy hydroelectric power plant infrastructure will unavoidably stretch further into places that have so far been unaffected by such developments.Meanwhile it is of vital importance for tourist destinations that are based on nature-based tourism to preserve their relative naturalness.The demand in the Western world for the use of natural landscapes for tourism and recreation has been steadily expanding, due to the growing number of visitors, increased leisure time, and a continued favorable disposition to wilderness and remote landscapes.Furthermore, the economic prospects of nature-based tourism are very promising in many northern regions given that there is often an abundance of pristine nature and few other development alternatives.
It is generally assumed that power plants and accompanying infrastructure reduce the attractiveness of nature-based tourism destinations [3].Therefore, opposition against power plant development can be expected and it is often greater in natural areas which possess a high-quality landscape [4], than at destinations where developments are already in place [5].This can partly be explained via the changes to senses of place identity, place attachment [6] and a social construction of nature in which the "naturalness" of wilderness has been questioned, (e.g., [7][8][9][10]).
This study follows these ideas by evaluating the impact of a hydroelectric power station on the experience of tourists and whether their attitude differs from tourists in areas in which power plant construction is pending.The case comes from Blanda hydroelectric power station in northern Iceland-a region rich both in hydropower and in popular locations for nature-based tourism.
Large-scale production of hydroelectric power started in Iceland in the mid-1960s and currently the country produces the most renewable electricity per capita in Europe [11].There are plans for further development of hydroelectric power plants in areas that might create conflicts with nature-based tourism as most of the proposed plants are located in high-value natural areas.In recent years, nature-based tourism has become the largest export sector in Iceland with 83% of visitors claiming nature as the primary reason for visiting the country and nearly 50% state the country's pristine landscape and wilderness is the main attraction of Icelandic nature [12].Blanda hydroelectric power station is at the periphery of the uninhabited Central Highlands, referred to here as the Highlands.Research conducted among tourists has demonstrated that wilderness is an important part of the appeal of the Highlands [13][14][15].Yet, given the impending developments and their potential affect on the tourism sector, it is imperative that a better understanding on tourist perceptions of the impacts of power plants on the landscape is gained.
Based upon a questionnaire survey among tourists at Blanda Power Station the aim of this paper is to examine:

•
How tourists experience the area around Blanda Power Station and whether they perceive wilderness as a part of the attraction.

•
The attitude of tourists towards power plant constructions in the area.

•
The attitude of tourists towards power plants in Iceland.

•
Whether tourists' attitudes towards the questions above differs depending on main variables (i.e., nationality, age, gender, travel pattern, season).

•
Whether there is a difference in the attitude of tourists in the vicinity of Blanda Power Station and the seven other areas where power plant development has been proposed.
Bishop [16] argued that in the near future, landscapes will change significantly due to the development of renewable energy as a response to climate change.This will presumably result in power plant infrastructure becoming increasingly visible in the landscape in natural areas in many parts of the world [16].However, this brings up major public policy issues regarding the development of renewable energy versus its impact on the natural environment and the prosperity of economic sectors that rely on locations with high degrees of naturalness, such as the tourism industry.In countries and regions with an economically significant nature-based tourism sector that depends on natural areas and wilderness as an attraction, an understanding of tourists' perceptions of the effects of power plant construction should therefore become integral to policy discourse.If, as Nadaï and Van der Horst suggest, "Landscape has become a key arena for the debate on energy policy" [2] (p.143), then it is imperative that debate is informed and evidence-based with respect to the relative values of energy and tourism development and the interrelationships between these sectors.Consequently, this study addresses some of the most important issues with respect to sustainable development in peripheral and wilderness areas with significant energy development potential [17] that are also nature-based tourism destinations.
The next section discusses concepts of the social construction of nature, place identity, and place attachment in relation to the meaning of wilderness [6], along with how people perceive power plant constructions in natural areas.A description of the research area and comparative locations is provided, as well as an account of the methods that were employed and data processing.A comprehensive analysis of the questionnaire results is provided, with the main results discussed in the wider context of the policy and planning discourse surrounding such developments as well as the implications for future energy and tourism development.

Constructing Place
The geographical concept of 'topophilia' (love of/for a place) addresses the emotional connections between people and the physical environment as a way of admiring the landscape [2,18,19].The connection between humans and places has been looked at, for example, via the lens of 'place identity' which describes how the physical and symbolic characteristics of places add to peoples' sense of self or identity [20].'Place attachment' is a related concept, which consist of relations between behaviour, perception and feelings that are supposed to evolve through individual experiences with the physical environment.Local people usually have more experiences of neighboring areas as they use them more than others and are therefore assumed to develop stronger attachment to the areas [21].Thus, their opposition to environmental change is expected to be greater than those with weaker place attachments.This relationship has been studied empirically by Vorkinn and Riese [22] who evaluated the connections between place attachment and the local opposition against a proposed hydropower project in Norway.They showed that the stronger local people felt attached to the proposed area the more negative they were towards development, indicating that a power plant in the area would reduce place attachment.
In this context, a 'place' refers to a space that has been given a symbolic meaning by individuals and groups via processes of social and economic developments.Thus, a place is a dynamic concept that can change over time.Places are of various size/scale and their realties can vary.Some places are quite 'real' such as, for example, an island.Others, like wilderness, are more of an idea, at least according to social constructionists, e.g., [7,9,10], that fit perceptions of a landscape.However, this is a selective practice in which individuals tend to see what fits into their image of a place and their prior beliefs.According to Bell [23] people tend not to see, or forget more easily, negative visual experiences that do not fit their prior image of how the area should look like.Accordingly, the meaning people ascribe to certain landscapes depends on their preconceived image of how an area is supposed to look like.Social constructionists consequently argue that the perception of a landscape depends on individuals' knowledge and that such knowledge is constructed through communicative connections between people, as well as between people and institutions.From this perspective, environmental knowledge is therefore actively produced by individuals and groups rather than being a passive reflection of reality.For instance, if tourists assume an area to be wilderness and they understand wilderness as a non-human world with unspoiled nature, they may consciously or unconsciously avoid seeing human made modifications of the environment and thereby construct their perceived reality.Hence 'wilderness' according, to this approach, is a cultural and historical construction [24].
Studies among tourists in the various areas within the Icelandic Highlands have showed that despite human influence like roads, mountain huts and some other infrastructures, most tourists still experience the area as wilderness.Thus, the social construction of the wilderness in Iceland suggests that tourists see what they want to see and that they make and preserve in their minds an image of the Highlands as wilderness or unspoiled nature [25,26].As Devine-Wright [27] observes, consideration needs to be given as to how power plant constructions 'fit' with the socially constructed ideas and the symbolic image of how the area 'should' look.Therefore, it is really the alteration of a certain landscape that causes the most dissatisfaction but not the new landscape as such.Consequently, new power plant developments have to fit in with the existing place identity and its symbolic dimensions in order to be acceptable to affected communities [6,19,28,29].
Much research [30][31][32][33][34][35] highlights that the most important factor preventing people's acceptance of renewable energy are their visual perceptions of the appendant infrastructure.Built structures seem to reduce wilderness experiences considerably.Although the type of construction does not appear to matter, whether they are directly related to tourism and outdoor recreation, or related to other industries, e.g., dams and hydroelectric power plants [13,[36][37][38][39]. Studies among tourists in nature destinations in Iceland have similarly shown that tourists are rather negative to pending power plant constructions albeit that they are renewable [13,40,41].That also goes for hydroelectric and geothermal power plant proposals [42] wind farms [41], and transmission lines [40].
There is a large difference between the visibility of the various renewable energy types and the energy landscapes they create.The visual contrast in the landscape from a hydroelectric power plant is, for example, far less than that of a wind farm.Wind farms have very large structures with reflective surfaces, and therefore contrast strongly with the natural environment.As a result, they are usually visible over long distances.For example, in Western American landscapes, Sullivan et al. [43] recommend a radius of 48 km for assessing the visual impact of a wind energy facility.Hydroelectric power plants, on the other hand, create a very different visual experience.They involve housing where turbines and transformers are kept but these buildings are often built underground and therefore have only limited visual impact.
Hydroelectric power plant infrastructure comprises dams, canals, reservoirs, transmission lines, buildings and roads.Reservoirs can create their own landscape signature by taking the appearance of a natural lake, which could potentially create a more positive experience of an area.As Henry David Thoreau (1854) stated in Walden: "A lake is the landscape's most beautiful and expressive feature.It is earth's eye; looking into which the beholder measures the depth of his own nature."However, the surface of reservoirs fluctuates and when it is low it may be an eyesore as the bank can be covered in silt that sometimes can also cause erosion and feed sandstorm when the wind blows.Furthermore, reservoirs lie in depressions in the landscape that are often vegetated, so when the vegetation disappears under the reservoirs the ecological landscape is changed substantially.Hydroelectric power plants also often alter the appearance of the neighboring environment as waterfalls can disappear or their flows reduced, river turbidity altered, and rivers and canyons can become dry.Such events that can affect the recreational use of whitewater habitats due to reduced kayaking and rafting opportunities [44,45], as well as affecting fishing and hunting of water-fowl.
All types of power plants need a way to transfer the energy from the production site to the demand site and therefore transmission lines are a necessary accompanying structure.Due to their visibility they therefore have a substantial impact on landscape perception and attachment towards the area.
New or improved roads are usually unavoidable for the construction of new hydroelectric power plants.However, while roading can have a substantial impact on visual amenity, it can also make locations much more accessible to visitors and therefore have a major effect on what type of tourism develops, what kind of tourists visit and their number [38].
Tourist preferences towards nature destinations varies along a broad spectrum, from appreciation of wilderness with no or little human intrusion to places with considerable infrastructure that have been changed substantially by humans.Different variables can be used to differentiate tourists' preferences in nature destinations.One widely used method [46][47][48][49] is the so-called Purist Scale model which divides tourists into the groups purists, neutralists and nonpurists according to their satisfaction with qualities and settings in wilderness and other nature destinations.Purists prefer to travel in a pristine environment, with primitive facilities and search for solitude, while nonpurists do not notice or get disturbed by environmental change, appreciate good facilities, and are not disturbed by the number of travelers.Stefánsson, Saeþórsdóttir and Hall [40] found that purists are more negative towards transmission lines and wind turbines than neutralists and nonpurists.This study further investigates the extent to which different groups of tourists respond to power generating infrastructure in a high natural quality landscape.

Hydroelectric Power in Iceland
Iceland is the largest producer of renewable electricity per capita in Europe and produces 2.07 times more than Norway, which is the second largest.Iceland is ranked in 15th place among European countries with regard to total production of renewable electricity in total [11].Hydroelectric power produces about 73% of the electrical power produced in the country, while 27% comes from geothermal sources [50].About 80% of the total energy produced in Iceland is used by a few (<10) power-intensive industries [51]-all owned by foreign companies.The low price of energy is the main reason that transnational power intensive industries are located in Iceland [52].
The Icelandic population is about 335,000 people and almost all settlement is below 200 m.About 63% of the population lives in the capital area, and the rest lives in towns and farms scattered along the coast and in valleys that penetrate the country to varying degrees [53].The interior of Iceland, the Central Highlands, cover approximately 40% of the country and form a high plateau at 400-700 m altitude.The area is largely desert-like though occasional depressions and valleys are vegetated.The landscape is diverse and, in many ways, unique, characterized by wide open spaces, with vast lava fields, sandy or stony deserts, geothermal areas, mountains and large ice caps which melt water runs from and forms powerful glacial rivers.The area is uninhabited and there is little visible evidence of human influence except mountain huts for travelers, a small number of power plants and primitive gravel roads.There are two main roads that cross the Highlands between the north and south.One of them is Kjalvegur, which passes the research area presented in this study.
Utilizing rivers to produce hydroelectric power began in Iceland in 1904 when the first hydroelectric power plant was built and for the first half of the twentieth century small hydropower plants were built in towns and at farms in all parts of the country except in the Highlands.In the beginning, such developments were solely for domestic use but, in the late 1960s, the first aluminum smelter was built.To provide the smelter with power, Landsvirkjun (The National Power Company) was set up with the aim of building and operating a new power station, by far the largest in Iceland.
It was built at the southern periphery of the Highlands, where the river Þjórsá was harnessed as it runs southwards from its origin in the glacier Hofsjökull in the center of the Highlands.This marked the beginning of hydroelectric power production in the Highlands.In the following years, six more plants were built in the same area.The first hydroelectric power plant, Blanda Power Station in the northern part of the Highlands, was built in 1991 when the river Blanda was harnessed.Blanda, like Þjórsá, also flows from the glacier Hofsjökull but to the north.In 2007 the largest hydroelectric power plant was built in the northeast of the Highlands.
The harnessing of geothermal energy started in 1978 when the first plant was built.So far, no geothermal power plants have been built in the Central Highlands but this could change, as some of the most energetic geothermal areas are located there.Geothermal power plants consist of large buildings for turbines and steam separators, as well as drill holes that sometimes steam that are connected to the main buildings by long pipelines.
Significantly, tourism has benefitted from increased access as a result of roads constructed for the building of power plants.Increased accessibility can have enormous impacts because of the growth in visitor numbers and the further along a destination is in the development process the more obvious the environmental problems tend to be [54,55].

Blanda Hydroelectric Power Station
The river Blanda is one of the longest rivers in Iceland, about 125 km long and with a catchment area of about 2370 km 2 .It mostly contains glacial meltwater, although several spring creeks join its stream.The surrounding landscape is characterized by a rather homogenous and expansive plateau at 400-600 m.a.s.l., which is covered by moraine and glaciofluvial deposits.The installed capacity of the power plant is 150 MW (Landsvirkjun, 2016).The power station building lies at the highland border by the northern part of Kjalvegur mountain road.The bulk of the power plant construction itself lies underground, although above ground there is a building and nearby lies a personnel residence along with some other constructions.Further inland from the power station are two reservoirs that have made their mark on the landscape.The larger of the two is called Blöndulón, and at 57 km 2 , is the third largest inland body of water in Iceland and is situated approximately 25 km by road from the power station building.The other reservoir is the 5 km 2 Gilsárlón, located 5 km by road from the power station.In addition, there are a few natural lakes used to canalize water distribution.The mountain lakes were all crystal-clear before the power station was constructed but because of their role in water distribution are now gray colored.The reservoirs and the former natural lakes are connected through diversion canals that are about 9800 m long.Five dams have been built in the area.The three main dams are between 44 and 34 m high (Landsvirkjun, 2016).As a result of lake expansion and the formation of reservoirs, about 62 km 2 of land was submerged and some of it vegetated.As compensation, the power company financed the construction of fences, huts and stables in the area and the nearby heaths were reclaimed and cultivated.Roads were also built and asphalted.The electricity from Blanda Power Station is conducted through two 132 kV high voltage transmission lines that lie to the north from the power station.In addition to infrastructural developments, the landscape has been altered due to the Blanda River no longer flowing along its natural course, although the water flowing down it has become clearer.

Data Collection
The method employed in this study was a questionnaire survey conducted among tourists in the area.Since the objective of the research was to assess the impact of Blanda Power Station and its pertinent infrastructure on the experience of tourists, the respondents had to have travelled through the area where the power station infrastructure is visible before answering the questionnaire.Moreover, they could not have travelled so far from the area so as to not realize what area they were being asked about.As mentioned, the landscape around the power station contains no specific location that all tourists stop to visit.Therefore, reaching a sample group in the area was methodologically challenging.
The method adopted for the research meant that two interviewers were working simultaneously.One interviewer was located at the northern end of the power station's impact area, by the crossroads of Kjalvegur and the road to the power station/employee building.The questionnaire was handed to the tourists that were entering the Kjalvegur mountain road from the north.The other interviewer was posted in the southern part of the area, on Kjalvegur mountain road just north of the mountain hut Áfangi, where a parking space/rest area and picnic table has been set up.There the questionnaires were handed to the tourists that were coming from the south via Kjalvegur.The interviewers had a signpost in order to draw the attention of tourists.All the passengers in the cars that stopped were asked to answer the questionnaire except for the driver.Those who agreed to participate were handed a questionnaire they answered while driving through the power station impact area, which took about 15 min.Once they had filled out the questionnaires they were delivered upon meeting the interviewer on the other side of the area.Usually the duration of the drive gave the respondents ample time to fill out the questionnaire, nevertheless, if the tourists had any questions left, they would stop the vehicle and finish answering before continuing on their journey.
Tourists on organized tours were approached differently because it is usually more time-consuming to hand out and explain a questionnaire to a group of tourists in a bus than to individuals in private cars, plus the schedule of organized tours is generally full, leaving them with little time to answer.Tour guides or bus drivers were requested to take questionnaires with them and the passengers were asked to respond whilst on the bus.The interviewers gave the guides/drivers a stamped envelope and were asked to mail the questionnaires back to the researchers.
The data collection over the summer took place for two weeks; between the 28 June until the 4 July and in the autumn between the 2 and 8 September 2016.The total number of private and group vehicles that drove through the area was 479 during the summer and 369 over the autumn.
The number of vehicles that did not stop to participate in the survey were 150 over the summer and 51 during autumn.Hence, the response ratio compared with the number of vehicles was 67% during the summer and 86% over the autumn.In total, 1078 questionnaires were answered and handed in, 617 in the summer and 461 in the autumn.

Questionnaire and Data Analysis
The questionnaire was available in four languages, i.e., Icelandic, French, German, and English.It comprised 27 questions, some had a number of subquestions.Their subject can be divided into the following categories: 1.
Background questions regarding age, gender, residence, and a question that categorizes tourists into purists, neutralists, and urbanists on the purist scale.2.
Questions concerning the stay in the area, e.g., experience and attraction and whether wilderness was part of that.

3.
Questions about appropriate infrastructure in the research area.4.
Questions about attitudes towards the construction of the various types of renewable power and whether the production should be in the Highlands or in Lowlands.

5.
Questions regarding attitudes towards Blanda Power Station and its impact on tourists' experience.6.
The impact of further harnessing of energy on tourists' interests in returning to Iceland.
The questionnaires contained a few questions that included the word 'area', as in, for example, "how do you perceive the area?" and "do you think wilderness is a part of the appeal of the area?"It has been an acknowledged dilemma in similar research that tourists place distinct meaning to the concept of an area [56].In this research concerning the impact of the Blanda Power Station on the experience of tourists, the area in question is not an officially defined area with borders in the manner of a nature reserve or a municipality.In order to assist the tourists in realizing what particular area was under discussion, a map of the research area and the infrastructure pertinent to Blanda Power Station was handed out to the respondents along with the questionnaires (Figure 1).The northern border of the area that is shown on the map is right north of the power station main building and its outgoing transmission line, while the southern border is just south of the southern part of the Blöndulón reservoir.Kjalvegur mountain road can be seen in the middle of the map and the eastern and western borders of the area reach approximately 5 to 15 km east and west off the road.
However, not all individuals are equally proficient at reading a map and what is more, not all of the respondents dedicated much time to reviewing the map.Therefore, it is likely that on some occasions the questions relating to a specific area have been answered in view of the respondent's own definition of the area.This is, for example, rather obvious in a question regarding the duration of the tourists' stay in the area where it says that the respondents have stayed on average 2.6 nights in the area and that day tour visitors have stayed on average 3.4 h.Here the respondents must have had a much larger area in mind than the one the researchers were asking about and showed on the map that went along with the questionnaire.
A few questions were open and this gave respondents an opportunity to answer in their own words.However, the majority of the questions were multiple-choice closed-ended questions based on a five-point Likert scale, i.e., 1 = strongly disagree, 2 = disagree, 3 = neutral, 4 = agree, 5 = strongly agree.Certain means were calculated from the results in order to make a comparison between different aspects possible.Obviously, a comparison between different locations is always challenging as no two places are identical.The types of tourism activities and main attractions in the seven comparison areas are different (Table 1).The seven comparison areas have different degrees of medium to high naturalness.Two of them are in the center of the Highlands (Hagavatn and Nýidalur) with only a mountain hut The data was analyzed for information as to whether there was a statistically significant difference between tourists' answers depending on gender, age, nationality, place of residence in Iceland (capital versus rural areas), means of travel, duration of hiking tours, overnight and day tour visitors, along with the categories of the purist scale (urbanists, neutralists, purists, strong purists).The answers were also analyzed according to whether the tourists were arriving through the Highlands from the south or on their way to the Highlands from the north, after the season (summer and autumn), as well between first-time visitors and repeat visitors.Research was conducted related to pending power station projects in the summer of 2015, which was partly based on a similar questionnaire as the one presented here [57].That research was executed at seven areas.In the following analysis of the data a comparison is made between the answers from respondents at Blanda Power Station and each of these seven areas.This kind of comparison, i.e., between the opinion of tourists at an area where hydroelectric power plants have already been constructed and at places where there are proposals to construct power plants has, according to our knowledge, not been made before.Due to hydroelectric power plants' potential effects on tourism, and the likely growth of both sectors in the future, it is vital to have a better understanding of tourists' perception of the impact of power plants on the destination.
Obviously, a comparison between different locations is always challenging as no two places are identical.The types of tourism activities and main attractions in the seven comparison areas are different (Table 1).The seven comparison areas have different degrees of medium to high naturalness.Two of them are in the center of the Highlands (Hagavatn and Nýidalur) with only a mountain hut in the vicinity and a dirt road passing by.Three are in the Lowlands (Trölladyngja, Skagafjörður and Seltún).Skagafjörður is an accessible rural area with farms and agriculture.Seltún and Trölladyngja are reachable in about 30 min from the capital area by car.Seltún is accessible by an asphalted road and is a kind of mass tourism destination for international visitors.Trölladyngja, on the other hand, can be reached by a dirt road and is mostly visited by domestic visitors.Two of the comparison areas (Aldeyjarfoss and Hólaskjól) are similar to Blanda by being at the edge of the Highlands.Although Blanda is the only place where a power plant has been constructed, there are some reservoirs approximately 13-15 km away from Nýidalur (Figure 2).
In order to examine whether there were differences between the abovementioned variables, a t-test was employed where there were only two groups (for example, gender and daytrip versus overnight visitors), while an ANOVA was used were there were three or more groups (for example, Nonpurists, neutralists and purists).In the cases where the ANOVA showed significant dissimilarities within a parameter the difference between specific groups was located through a post-hoc test.A Hochberg's GT2 was employed if the variance was the same and a Games-Howell post-hoc test if they differed [58].
In the following presentation of the results, the main outcome from the Blanda sample is displayed in a chart and underneath a table with the mean and the standard deviation as well as the results from the various statistical analyses.In the discussions the significant difference is set at a p-value below 0.05.

Tourists' Perception of the Naturalness of the Area
Tourists were asked an open question concerning what fascinates them about the area.The responses to this question were diverse, however, after encoding, ten categories emerged that reflect the most common answers.Some categories overlap, furthermore the responses of many fall under more than one category and therefore the total ratio is higher than 100%.What attracts most, or 52% of the respondents, is the view, open vast spaces, and beauty.Many (36%) say that they are attracted to the landscape and nature, while 26% mention the wilderness and uninhabited areas.About 13% list quietude and solitude, whereas plants and animals are named by 10% of the respondents.About 7% of tourists say that water appeals to them and four individuals specifically mentioned the reservoirs of Blanda power station.Of note, 6% mentioned areas outside the defined research area, shown on the map that followed the questionnaire, like the geothermal area Hveravellir, which is about 30 km away-a two-hour drive south of the reservoir Blöndulón.About 3% of respondents state that driving through the area is appealing to them and the same proportion mention harnessing of energy and/or green energy as an attraction.
A vast majority, about 92% of tourists in the vicinity of Blanda Power Station, feel that wilderness constitutes a part of the appeal of the area, 4% do not consider wilderness as a part of the attraction, while another 4% have no opinion on the matter.In comparison to the research areas of pending power station projects in the summer of 2015 [57], wilderness makes up for less of the appeal in the area surrounding Blanda Power Station.The areas where wilderness is regarded as a part of the attraction by the highest ratio of respondents are Aldeyjarfoss, Hagavatn and Nýjidalur (98%), followed by Hólaskjól, Seltún, Skagafjörður and Trölladyngja (93-96%), with Blanda with 92%.
Approximately 79% of the respondents go to the Blanda area to experience wilderness, 14% do not visit the area for this purpose and 8% are neutral to this question.A comparison with the research areas related to pending power station projects in the summer of 2015 shows that Blanda and Seltún are less visited to experience wilderness than the other locations.About 79% go to Blanda and Seltún

An analysis of visitors' attitudes, according to Stankey [59] Purist sScale, shows that there is a statistically significant difference between the average score in the eight areas (anova test F = 24,768, p < 0.001).Blanda is visited by fewer purists than the other locations, except Seltún, since purists are about 22% of all visitors in the Blanda area and 11% at Seltún.At the other locations the proportion of purist-urbanist is rather similar with about 27-38% being purists (Figure 3). to experience wilderness, compared with 92-94% of those that visit Aldeyjarfoss, Nýjidalur and Hagavatn, and 87-89% of Hólaskjól, Trölladyngja and Skagafjörður.An analysis of visitors' attitudes, according to Stankey [59] Purist s\Scale, shows that there is a statistically significant difference between the average score in the eight areas (anova test F = 24,768, p < 0.001).Blanda is visited by fewer purists than the other locations, except Seltún, since purists are about 22% of all visitors in the Blanda area and 11% at Seltún.At the other locations the proportion of purist-urbanist is rather similar with about 27-38% being purists (Figure 3).Tourists at Blanda were asked whether they felt that nearby infrastructure, that they know of but is out of sight, affects their experience of the wilderness/unspoilt nature of the area.The largest group, 47% of respondents, does not feel that nearby infrastructure affects their experience if it is out of sight and 32% consider it to have little effect.Less than 13% consider that it affects their experience somewhat, while 5% believe it affects their experience rather much and 4% say that it affects their experience very much.
Tourists in the vicinity of Blanda Power Station were also asked what infrastructure, or signs of human interference, could be present without the concepts 'wilderness' or 'unspoilt nature' losing their meaning.It was possible to select more than one option.According to 21% of tourists no signs of human interference could be present.On the other hand, over 80% feel that the presence of mountain huts and tracks by hikers and sheep do not make wilderness meaningless, 60% consider road tracks to be permissible and 56% man-made walking paths.Fewer (40%) regard reservoirs, fences (39%) and roads (33%) as permissible and ever fewer consider transmission lines (19%), visitor centers (14%), transmission towers (14%), power stations (12%), wind turbines (11%), and hotels (7%) as acceptable infrastructure without the concepts of wilderness/unspoiled nature losing their meaning.
The respondents were asked to describe whether they considered the research area around Blanda power station was natural or developed.About 63%, consider the area very natural, while 26% consider it rather natural.About 7% of tourists regard the area as rather or very artificial and 4% are neutral towards this question (Table 2).However, all of the places used from the 2015 research were perceived to be more natural [57].The attitude of tourists at Blanda Power Station did differ according to age, although the multilateral comparison does not show a difference between specific groups.There is also a distinction in attitudes depending on nationality, as Icelandic respondents consider the area less natural than the French, Germans, Austrians/the Swiss, Americans/Canadians, Beneluxians, the British/Irish and those that are categorized as "other nationalities".Neutralists regard the area as more natural than purists and those travelling in a private vehicle consider it less natural than those travelling in a rented car or on a tour bus.Those that have not visited the area previously consider it more natural than those that have been there before, while those that walked for three to five hours regard the area as more natural than the groups that walked for less than three hours.Tourists that were coming through the Highlands from the south along Kjalvegur also felt that Tourists at Blanda were asked whether they felt that nearby infrastructure, that they know of but is out of sight, affects their experience of the wilderness/unspoilt nature of the area.The largest group, 47% of respondents, does not feel that nearby infrastructure affects their experience if it is out of sight and 32% consider it to have little effect.Less than 13% consider that it affects their experience somewhat, while 5% believe it affects their experience rather much and 4% say that it affects their experience very much.

The Impact of Blanda Power Station
Tourists at Blanda Power Station were asked what impact the fact that the river Blanda has been harnessed had on their interest in travelling in the area.About 67% of the respondents stated that the power station has no effect on their interest in travelling in the area.Those that say the power station has a positive effect on their interest are more numerous (19%) than those that say it has a negative effect (13%).There is no statistical difference between groups regarding this subject except that it had a more positive impact on urbanists and neutralist than purists.
Tourists were asked whether they had noticed any infrastructure on their way through the area, the options being no or yes.About 90% of respondents said they noticed infrastructure, while 10% stated that they had not seen any infrastructure.Those that responded in the affirmative were then asked to specify what impact certain types of infrastructure, such as reservoirs, dams, canals, transmission lines, asphalt road and gravel road, had on their experience.The available options were that the effect was very negative, somewhat negative, no effect, somewhat positive and very positive.
Between 39-61% claimed that the various types of infrastructure had no effect on their experience (Figure 4).Transmission lines caused a much more negative effect on the experience of tourists than other infrastructure whereas about 54% said they had a negative effect.The reservoirs and the gravel road have a positive effect on the experience of 46-47% of those that notice them, and 10-13% say the impact was negative.The asphalt road was perceived somewhat more negatively.The dams and the canals had positive effect on 25-34% and negative on 14-21%.

Tourists' attitudes towards the construction of power stations in Iceland were surveyed and if it mattered as to whether the power station is located in the Highlands or in the Lowlands (Figure 6).Tourists are most negative towards transmission lines and wind turbines in the Highlands with 58-61% being rather or very negative in their attitude towards them.The number of tourists that are negative towards transmission lines and wind turbines in the Lowlands and hydroelectric power stations in the Highlands is higher (41-43%) than those with a positive attitude towards them (18-27%).The respondents are most positive towards further development of geothermal power stations in the Lowlands, with about 47% being positive.Approximately 36% of tourists are positive towards further development of hydroelectric power plants.Foreign tourists in the vicinity of Blanda Power Station were asked whether further harnessing of energy in Iceland would make it more or less likely that they would return to the country in the future (Table 14).About 75% state that further harnessing of energy would have no impact on their interest in travelling again to Iceland in the future.Approximately 19% of tourists say they would be less likely to return if there would be further harnessing of energy, while 7% would be more likely to return.
The French are less likely to return to Iceland because of further harnessing of energy than Germans, the Swiss/Austrians, Americans/Canadians, Visegrád Group inhabitants, Italians/Spaniards, the British/Irish and those classified as "other nationalities".Urbanists are more likely than any of the other purist scale groups to return in spite of further harnessing of energy.Neutralists are also more likely to do so than purists.Those travelling over the summertime are more likely to return if further harnessing of energy occurs than those travelling in the autumn.Other parameters do not represent a significant difference.Foreign tourists in the vicinity of Blanda Power Station were asked whether further harnessing of energy in Iceland would make it more or less likely that they would return to the country in the future (Table 14).About 75% state that further harnessing of energy would have no impact on their interest in travelling again to Iceland in the future.Approximately 19% of tourists say they would be less likely to return if there would be further harnessing of energy, while 7% would be more likely to return.
The French are less likely to return to Iceland because of further harnessing of energy than Germans, the Swiss/Austrians, Americans/Canadians, Visegrád Group inhabitants, Italians/Spaniards, the British/Irish and those classified as "other nationalities".Urbanists are more did not seem to particularly affect the experience of the tourists.About 39-61% of respondents claim it had no effect, depending on the type of infrastructure.Transmission lines have the most negative effect on tourists' experience as 54% claimed they had a negative impact.This is in keeping with other research conducted in Iceland [13,40,57], as well as abroad [29,60,61], that show transmission lines are the least desirable infrastructure in natural areas.This study furthermore indicates that the transmission lines had a more negative effect on the experience of the tourists that came from the Highlands, i.e., those that had been driving in the area with no permanent human settlement for 4-6 h than those who just left the inhabited lowland.It is noteworthy that those coming from the Highlands are just about to see the transmission lines when they are finishing answering the questionnaire while the ones coming from the Lowlands have had them in their sight for a while and even driven under them shortly before answering the questionnaire.This might be an indication that being in the wilderness makes you more sensitive towards human artefacts and constructions in the landscape compared to being in a cultural landscape.
These results are in keeping with an Icelandic study on the effect of transmission lines on tourists [40] which showed that tourists are more negative towards transmission lines in the Icelandic Highlands than in the Lowlands.Both studies [40] indicated that when it comes to the impact of transmission lines French respondents were very sensitive towards them.Nevertheless, this study does not show the variance between attitudes of Icelanders and the other inhabitants of Nordic countries, that the other Icelandic study [40] showed with respect to the strongest opposition to transmission lines.
This study also suggests that other types of infrastructure had a limited negative impact as 10-20% claimed them to have a negative effect on their experience.The gravel roads and the reservoirs raised positive feelings among about 46-47%.A few visitors even praised the lake/the reservoir as it presented a variation from the interminable sandy desert.The French tourists experience the reservoirs more positively than other nationalities, while the transmission lines had the most negative effect on their experience.Approximately a quarter of the respondents claimed that the canals and dams had a positive effect on their experience.
Despite the power plant infrastructure in the area most tourists regard the area as very natural, although 7% of tourists consider it developed.Nonetheless, in comparison with the seven locations studied in 2015 the Blanda area is considered less natural.The power plant does not seem to impair the image of the central Highlands as the vast majority of tourists, or 92%, consider wilderness a part of the attraction of the area.Nevertheless, in comparison with the locations in 2015 [57], wilderness is regarded as being less a part of the appeal of the area in the vicinity of Blanda Power Station.About 40% of tourists did not feel that the presence of reservoirs causes the concepts of wilderness and unspoilt nature to lose their meaning, 19% consider the presence of transmission lines to be permissible and 12% that of power stations.Still, the visibility of infrastructure is important for tourists, since just under half of them consider the infrastructure they are aware of but is not visible still affect their experience, while about a third feel that it has little effect, 13% say it has some effect, 5% state that the impact on their experience is rather significant and 4% regard it to be very significant.This situation reflects the idea of nature as a social construct, which suggests that the subjective reality of tourists is to a large extent based on preconceived ideas they have regarding the area.In light of this, the image of Iceland's central highlands as an unspoilt wilderness [25], could render foreign tourists oblivious to reality, i.e., they do not seem to notice the infrastructure present in the area they were travelling through.As Priestley and Evans [62] point out, people have a tendency to overestimate the actual visual impact of energy infrastructure they feel negatively towards.
Even though the existing power plant infrastructure around Blanda does not disturb tourists all that much, 37% of tourists are negative towards further construction of hydroelectric power stations in the Highlands, 35% are neutral and 28% of the respondents are positive towards further construction.Still, tourists at Blanda Power Station are more positive towards further hydroelectric power developments in the Highlands than the tourists at all the locations in 2015, except those by Seltún [57].Similar trends can be seen in the results regarding the development of hydroelectric power stations in the Highlands as towards the current infrastructure.That is, purists, the French, and those that have visited the area previously, are more negative towards hydroelectric power stations and geothermal power stations in the Highlands as well as in the Lowlands than those that are visiting for the first time.This situation reflects Vorkinn and Riese [22] work, which suggests that the more people feel attached to an area the more negative they are towards proposed power plants.

Explanation of the Results
Various explanations can be provided to help explain these results.One is that possibly the design of Blanda power plant and accompanying structure is good and well-adjusted to the landscape.Another reason for why the power infrastructure in the Blanda area causes little disturbance to the experience of tourists could be its locational setting.The landscape is homogenous and does not have some major natural attractions as at some of the other destinations, i.e., where there is a waterfall, which would disappear if the proposed hydroelectric power plant would be built.
The statistical comparison made in this study between the attitudes of tourists in the Blanda Power Station area and the seven research areas in 2015 showed that there is a difference between these locations since the attitude at Blanda towards power plants is more positive.There is one exception, which is Seltún.Tourists at Blanda (and Seltún) are dissimilar to those at the other locations when it comes to the division of tourists according to the purist scale, as at Blanda (and Seltún) there are fewer purists and more urbanists and neutralists than at the other six areas.Consequently, it appears that those who have the highest demands for what can be considered unspoilt nature visit the Blanda area to a lesser extent than the other areas (except Seltún).One of the possible explanations for this could be self-selection, given that tourists are aware that a power station has been constructed at the northern edge of the Central Highlands.Thus, those who have high demands for unspoilt nature avoid travelling to the Blanda area and direct their travel somewhere else in the Highlands.Accordingly, it is possible that the Blanda Power Station has diminished the areas' attraction for purists.Indications from other research suggest that a certain type of tourist stops visiting an area after power stations have been constructed.For instance, the research of Devine-Wright [27] has shown that alterations in the landscape of areas that are in opposition to the image and experience that individuals connect with them can lead to their abandonment of the areas.
This study showed that all types of power plant infrastructure had greater negative effects on purists than on urbanists and neutralists.This study, as well as others in Iceland [14,37,49], have also shown that the types of tourists travelling to the various parts of the Highlands of Iceland vary substantially, mostly according to the accessibility of the destinations.Destinations seem to appeal to different users not only depending on their accessibility, which goes hand-in-hand with the installations and infrastructure on site, but also the number of tourists.Increased access to tourist destinations is often a side effect of power plant developments, which then changes the type of tourism and what kind of tourist visits the area, as well as the overall number.An example of this can be seen in Landmannalaugar, the most visited highland destination, where access was increased after the harnessing of energy in the area of Tungnaá and Þjórsá in the late 1960s.As a result, the area is relatively accessible and has become well-known among travellers who come to Iceland.The number of tourists visiting the area is quite high and fewer purists visit the area now and instead seek more secluded areas [55].It is therefore possible that, at Blanda, certain tourist types (purists) have moved away from the area to more remote and more natural locations as has happened in Landmannalaugar [14,55].
At the same time, a new type of tourism has started at the river Blanda, which is salmon angling.Before the hydroelectric power station was built, a lot of sediments were transported by the glacial river so the water was gray and even though salmon was in the water it could not see the bait.But when the river was stilled behind the dams the sediments it contained sank to the bottom of the reservoir.Since the power plant was built, the river has become clearer and is now one of the best salmon rivers in Iceland.Over half of tourists in the vicinity of Blanda Power Station state their interest in visiting power stations visitor centers while travelling in Iceland.Urbanists and neutralists are more interested in such visits than purists.Three out of every four tourists feel that further harnessing of energy would not affect their interest in a second trip to Iceland, while a fifth of tourists believe that it would make them less likely to return.There is a considerable difference between the impact of further energy production on tourists, depending on whether they are purists or urbanists.These results suggest that further energy infrastructure would have a more positive than negative effect on the interest of urbanists in travelling to Iceland, while the impact on purists would be negative.Moreover, the impact of further harnessing of energy would be more negative on the French than on most other nationalities with the French less likely to return to Iceland if more power stations are constructed.

Conclusions
The results of the study provide interesting insights into how tourists perceive the impact of energy infrastructure in areas with high naturalness values.The main findings of this study are that most tourists in the vicinity of Blanda Power Station are satisfied with their stay in the area, while 8% are dissatisfied with the main attractions of the area: natural beauty, vast open landscape, quietude and calm.In spite of the fact that Blanda Power Station is on the edge of the Central Highlands, close to inhabited areas and power infrastructure, such as reservoirs, dams, canals, roads, and transmission lines can be found there, 92% of tourists consider unspoilt wilderness a part of the attraction of the area.Nevertheless, this percentage is lower than at the locations of the comparative 2015 research [57].Accordingly, Blanda Power Station does not seem to impair the Central Highlands' image as unspoilt wilderness for the tourists passing through the area.Up to 87% of tourists say they did not notice the power station and its appendant infrastructure.
Most tourists find the area surrounding Blanda Power Station natural, although 7% of tourists consider it artificial.Approximately 67% of tourists' state the existence of the power station does not affect their interest in travelling in the area, while a slightly higher percentage of respondents say the effect is positive (19%) rather than negative (13%).Therefore, perhaps unsurprisingly, over half of tourists in the vicinity of Blanda Power Station claim to be interested in visiting a power station visitor center while travelling in Iceland.With respect to the application of the purist scale, 65% of the tourists in the vicinity of Blanda Power Station are neutralists, 20% are purists, 14% urbanists and 1% strong purists.There were considerably more purists at all of the research areas in the study of 2015, except at Seltún [57].
These results are significant in the Icelandic context given the current substantial increase in visitors to the country, the majority of which identify nature as a major reason for visiting, and debate over the extent to which tourism may be affected by planned and future hydroelectric and other energy developments.The results here suggest that, on the whole, hydroelectric infrastructure has only limited effects on tourist perception of high areas of naturalness, although transmission lines have been identified as having a far greater impact [44].This does mean that with careful planning, including potentially the undergrounding of some transmission lines, hydroelectric developments may be relatively compatible with tourism in some circumstances.However, it should be stressed that the limitations of the study to this particular location and time of research, even given its comparisons to previous studies [57], may possibly reduce the applicability of the results in a wider context.Nevertheless, it appears that the research may significantly inform planning and policy debates with respect to the relationships between hydroelectric and other energy developments and tourism.In this context it is therefore very important to keep in mind that areas appeal to different user groups depending on their characteristics, as well as on what energy installations and infrastructure are in place.Therefore, it must be considered what group of tourists makes use of an area when the impact of infrastructure on experience is being researched and, in a wider tourism planning and marketing context, what type and number of tourists are being sought.
