1. Introduction
Sustainable development is an essential and popular concept in tourism, and its importance for the sector has been widely discussed in tourism literature [
1]. The sustainability of tourism has been examined by assessing its environmental, economic, and social impacts on society or local communities. Sustainable tourism has been defined as “
tourism that takes full account of its current and future economic, social and environmental impacts, addressing the needs of visitors, the industry, the environment and host communities” [
2] The environmental aspect of sustainability must be emphasized, since the recent fast economic and social developments have led to degradation of natural resources, such as water, in many parts in the world. The United Nations approved the 2030 Agenda for Sustainable Development in 2015 with 17 Global Goals, including the sixth goal -
“Ensure availability and sustainable management of water and sanitation for all” [
3]. The world water resources are under threat and, therefore, it is crucial to address vital resource challenges and adopt strategies towards sustainability. A significant body of evidence already suggests that humanity’s water consumption practices are unsustainable [
4].
Among water resources, lakes are vital natural resources for the human being and to ensure sustainability of the lake environment is of high interest for population and industries. As stated by researchers, the lakes are essential environmental resource, and sustainable management initiatives and interventions from the local authorities and policymakers are required to preserve them [
5,
6].
In the context of tourism, lakes are considered important resources ([
5,
7], due to their pleasant nature and attractive landscape, which make them meaningful places, often leading to positive mental images and feelings ([
8]. Nowadays, lakes are the main tourist attractions for many destinations, as is the case of Lake Balaton in Hungary, of some Australian and Finnish lakes, Great Lakes and those of the English Lake District[
9]. In this context, literature suggests that the quality of water is of high value for the lake tourism and sustainability of the lake destinations ([
9,
10], since it is essential in attracting the tourists and influences an important part of their holidays [
4]. Moreover, the importance of sustainable management of water resources for the tourism sector has been acknowledged by official organizations, such as the UNEP and the UNWTO, which have issued several programs aiming to address water challenges [
11]. The UNWTO organized its World Tourism Day programme under the theme “
Tourism and Water: Protecting our Common Future” in 2013 [
11]. The programme calls to bring greater attention to the potential role of tourism in more sustainable water management practices.
The interest in examining water and tourism relationships has increased during the last decades [
12].
Some attention has also been paid to lake tourism and lake destinations [
13,
14]. Some authors highlighted the urgent need of environmental protection enhancement and minimization of environmental threats in lake tourism development, to enable sustainable development [
15]. Despite environmental concerns arising on lakes’ ecological state, few studies were focused on lake tourism and lake destinations ([
16]. Consequently, research work focusing on perceptions on lake destination is limited [
6,
17,
18]. There are studies examining the influence of tourism development on lakes’ environment [
19], exploring sustainable tourism planning in lake destinations [
20,
21,
22], assessing the perception on lake destinations [
6,
17,
18,
23] and appraising satisfaction and loyalty towards a lake destination [
24,
25]. Nevertheless, to the authors’ knowledge no study is known that analyses the impact of visitors’ perceptions concerning lake destination, with a special focus on lakes’ sustainability aspect, on satisfaction with lakes and respective destination, as well as on loyalty towards lake destinations. Considering all these aspects, this study aims to fill this gap by proposing and testing a model to examine the effects of visitors’ perceptions concerning lake destinations (including those related to lakes and the surrounding territory), with a special attention to sustainability perceptions of lakes, including water quality and lack of congestion dimensions, on satisfaction and loyalty towards lake destinations. The aim is to help improve lakes’ sustainability and, consequently, visitors’ satisfaction with lake tourism destinations, as well as tourism development of these regions by increasing visitors’ loyalty.
2. The sustainability of lake destinations
Lakes are freshwater systems, which play a vital role for humanity, environment, and economic sectors. The importance of the lakes for the tourism has also been acknowledged, despite the existence of few studies on lake tourism and lake destinations [
8,
9,
13,
14,
16]. There are some countries where the lakes play an essential and unique role in promoting the country or some regions as tourism destinations [
9]. Thus, ensuring sustainability in lake destinations through a supply of water resources of good quality and guaranteeing that there are no congestions, are fundamental issues for tourism development in these areas [
21]. Moreover, water is recognized as a key resource upon which the attractiveness of a destination may depend [
26]. Therefore, the visitors’ perceptions on lake destinations, and mainly on their sustainability, are crucial since they may influence their future travel behaviors towards these places.
The increasing population, the industrial use of water and the growing needs of agriculture are putting extraordinary pressure on lakes and threating the sustainability of lake ecosystem [
27], which is not favorable for the tourism sector development. Some authors stated that in case of water crisis caused by various external factors, the tourism industry will be the most seriously impacted [
28]. Previous research related to water and tourism is predominantly concerned with tourism impact on either water quality, water quantity [
29], water consumption issues ([
12] and the water quality challenges rising from tourism development [
15]. Many researchers are concerned with the water resources challenges and reinforce the relevance of its efficient use, protection, and implementation of sustainability practices. In the context of the lakes, the researchers believe that water quality assessment indexes can be useful in monitoring the environmental state of the lakes, and helpful for local authorities in taking certain steps and measures towards sustainability of natural resources [
27].
Another relevant sustainability issue is congestion [
30]. The excessive concentration of visitors during peak season in nature-based destinations may not only cause degradation of natural environment and threat the sustainability of the resources, but also negatively influence the visitors’ destination perceptions. As noted by the researcher [
31], crowding and noisiness at Sun Moon Lake National Scenic Area in Taiwan influences the mood of visitors and leads to negative experiences. Ensuring a balanced number of visitors is of vital importance for lake destinations due to its vulnerable ecosystem.
Despite lakes are important attractions, generating visits to tourism destinations [
16] and possibly a growing sustainability awareness, there is little research exploring this interdependence, probably because lake tourism is an emerging type of tourism. Nevertheless, visitor perceptions of lake destinations arguably impact satisfaction levels and loyalty [
25]. Since lakes are central to the tourist experience in lakeside tourist destinations [
6], perception is expected to determine visitors’ behavioral intentions. A deep understanding of how the lake destination perception is formed is thus of central importance.
Lake destinations can differentiate themselves on several dimensions. Part of the lake’s destination perceptions is determined by how people perceive the lake itself. In this context, some authors [
16]point out that the lacustrine tourism environment encompasses not only the lake itself, but also its shore area, including the infrastructure and facilities that enhance it as tourist attraction. The lake is the main resource in lake destinations’ development, combined with other surrounding resources that form the lake environment [
23].
Research [
6,
23] also suggests that lakes are heterogeneous regarding water quality, the lake environment, and the extent of external pressures on the use of resources around the lake, namely the congestion on lakes. Regarding lakes, water quality could be considered an important perception aspect and one of the key components influencing destination selection decisions [
9]. Some studies have investigated water quality perceptions in a recreational or, specifically, a tourism context [
6,
32]. However, assessing visitors’ perceptions of water quality is a complicated issue, since not all visitors possess enough knowledge and information to evaluate it [
10]. There is also no consensus regarding the appropriate model or set of attributes to measure perceptions of water quality, possibly due to the multidimensional character of phenomena such as water quality or water pollution. Thus, some researchers have proposed using attributes of visual water quality characteristics, explaining that readily observable phenomena are more helpful when assessing overall perceptions towards water quality [
10]. Observable variables of water quality characteristics (color, odor, level of water, existence of sediments, algae, animal waste) mentioned in some studies on water quality [
32,
33] may be also helpful in this context.
Growing human and tourism activities can themselves threat the lake´s vulnerable environment. Changes in water quality and availability may cause negative impacts for tourism, which is not favorable for the mentioned sector. This happened in Québec, where many of the lakes are actively used by tourism and recreational activities, which led to algal blooms [
34]. Thus, nowadays the water quality of the lakes in Québec is a bigger concern than water availability. Other researchers also argued that decreasing water quality is already a barrier for sustainable development of the tourism industry in some regions [
35]. Pollution and congestion are considered sustainability challenges in a destination [
30,
36].
Other features of the lake and shore area, besides water quality, can affect visitors’ assessment. These features include the variety of the wildlife on the lake, the beauty of the landscape, peacefulness and opportunities to engage in water-based activities such as swimming, boating or fishing [
6,
23]. Regarding this last aspect, some research analyses the importance of lake water for recreational activities [
14,
33]. Another important component of lake perceptions - the lake environment - encompasses, besides water, the whole lake ecosystem, its accessibility, peacefulness and natural beauty, along with opportunities to carry out water-based activities and the tourism infrastructure on the shore.
The development of lake destinations demands tourism facilities, along with various services and activities, which presence may affect perceptions of lakes [
6,
24], mainly when there is a high quantity of facilities. In addition, heterogeneous use of lakes may not only affect the fragile lake ecosystem, but also give rise to conflict between stakeholders, which may affect visitors’ assessment of the lake [
9,
13]. Thus, a lack of congestion in and near the lake due to overuse or conflict between users (who may want to use the land for agriculture, industry, and tourism, among other activities) may lead to a positive assessment of a lake.
There are other components at lake destinations, located a little away from the lake itself, that may also be of importance. For some researchers, accommodation [
6,
23], tourist offices [
23], restaurants [
6], shopping areas and parking [
37] are factors that may influence the lake destination perceptions. In addition, some researchers refer to the history and heritage of the area [
7]to the friendliness of local people or to cultural attractions in the process of lake destination assessment [
23]. Others emphasize the beauty of the lake landscape [
7]. Some natural features of lake destinations, even those unrelated to the lake, such as the presence of mountains and valleys or a pleasant climate, may also influence the visitor’s perceptions [
13,
37].
3. Impacts of lake destination perceptions on satisfaction and loyalty
According to previous studies, the more positive is the visitors’ assessment of a destination, the higher is likely to be these visitors’ satisfaction level [
38,
39]. In the context of lakes, the degrading state of the lakes due to the various uses of the lakes by population – such as industry, agriculture and tourism –, may influence visitors’ satisfaction. Some authors [
5]pointed out that low water quality, including poor smell, color or a polluted water surface, may affect experience outcomes. Others [
6] analysed the effect of polluted lakes in China on the satisfaction level of visitors. The authors [
6]noted that
“differing degrees of pollution may exist” and that a lake without aquatic life may still attract tourists to the destination due to its pleasant visual aspect. Since the water quality dimension has received greater attention from lake stakeholders and researchers [
5,
6,
32,
33,
40] , it is expected to be one of the most influential predictors of visitor satisfaction with the lakes. Despite the lack of research in this scope, it is likely that the various dimensions of perception of lakes, not only those regarding water quality, but also perceptions on the lake environment (the natural and built surrounding environment) and on the level of congestion, influence visitors’ satisfaction levels with the lakes. Therefore, it is posited that:
H1: Satisfaction with the lakes is positively influenced by perceptions of water quality.
H2: Satisfaction with the lakes is positively influenced by perceptions of lake environment.
H3: Satisfaction with the lakes is positively influenced by perceptions of no congestion.
Researchers [
38,
39]found that the more positive the perception of the destination is, the higher the visitor satisfaction tends to be.
Despite increasing interest in destination image and its impact on satisfaction, as mentioned before, the case of lake destinations has not been sufficiently investigated [
41]. Some lake destination attributes, namely tourist facilities and cleanness were found essential antecedents of satisfaction, while others explored the influence of homestay facilities on tourist satisfaction [
24]. As mentioned before, there is growing interest among researchers on perceptions of water quality and the recreational use of lakes [
6,
32,
33]
Nevertheless, there is still no consensus on the influence of the perceptions of certain dimensions of lake destination image, such as natural and cultural attractions, along with public and private amenities. Taking into consideration previous research carried out in the tourism field, the following hypotheses are set up:
H4: Satisfaction with the lake destination is positively influenced by perceptions of tourist facilities and services provided.
H5: Satisfaction with the lake destination is positively influenced by perceptions of natural features.
H6: Satisfaction with the lake destination is positively influenced by perceptions of cultural heritage.
As widely acknowledged, the lakes are the main resource and the key attractions in lake destinations [
9,
13,
14,
16]. Overall satisfaction with the lakes, which is formed based on the visitor’s perceptions of various lakes dimensions, can be an essential antecedent of satisfaction with the whole lake destination.
H7: Satisfaction with the lakes has a positive influence on satisfaction with the lake destination.
There is a consensus among researchers that travel satisfaction is crucial for successful destination businesses and products, and to promote willingness to revisit the destinations [
42]. Moreover, the positive influence of satisfaction on behavioral intentions (intention to revisit and willingness to recommend) have also been examined and empirically confirmed in the case of tourism destinations [
25,
43,
44,
45]. This logic can be applied in the case of lake destinations. Moreover, research [
46] reveals that satisfaction with the lake destinations is likely to positively contribute to loyalty towards these destinations. Therefore, it is believed that satisfaction with both the lake and the lake destination are likely to have a positive impact on behavioral intentions, namely on destination loyalty, including the willingness to recommend and revisit the destination. More precisely, it is suggested that:
H8: Satisfaction with the lakes has a positive influence on lake destination loyalty.
H9: Satisfaction with the lake destination has a positive influence on lake destination loyalty.
Based on the above hypotheses, the following conceptual model is proposed (
Figure 1).
6. Conclusions
The research model proposed and tested in this paper using PLS-SEM provides important insights into lake destination perceptions, and its effects on satisfaction and loyalty, emphasizing the importance of the sustainability of lakes in this context. All the hypotheses of the study were confirmed. Therefore, the research undertaken in this paper provides important theoretical contributions and practical implications that will be identified below.
As far as theoretical contributions are concerned, first, a comprehensive set of items that may be adopted to assess the visitor’s perceptions of the lakes and of the entire lake destination, with special attention on the sustainability aspect, is identified. This measurement instrument may be used in various contexts where lake destinations are found. This extends certain previous studies, which mostly rely on assessing a restricted part of the lake destination image, namely that referring to the lake [
10,
32,
33,
61].
Second, as stated by [
30] the researchers, most of the research works on sustainability in tourism focus on the residents’ perspectives, while the present study is concentrated on visitors’ perceptions, which adds value to sustainability studies in a lake destination context.
Third, the empirical study expands the research on the lake destination perceptions, not only showing that these perceptions tend to have a positive influence on satisfaction regarding this kind of destination, but also highlighting the high relevance of the environmental aspects of the lake destination, such as water quality, which is the most important determinant of satisfaction with the lake in the present study. Furthermore, natural features also appear to be the strongest determinants of satisfaction with the lake destination. Nevertheless, positive assessment of other dimensions of lake destination, namely lake environment, lack of congestion, tourist infrastructure and cultural heritage are also essential in ensuring satisfaction with the lakes and lake destination.
Fourth, the fact that both water quality and inexistence of congestion had a significant direct impact on satisfaction with the lakes and a significant indirect impact on both satisfaction and loyalty towards lake destination was also a very important finding concerning the relevance of lakes to visitors. This, in addition to the conclusion that the perceptions on water quality were the component of lakes with highest impact in this context, provides empirical evidence of the relevance of the sustainability of the lakes to ensure satisfaction and loyalty regarding lake destinations. Nevertheless, comparing the impact of different sustainability features, environmental sustainability issues, namely water quality, seem to have more impact on satisfaction with lakes than the social sustainability dimension, namely the absence of congestion, probably because the natural environment of the lake destination tends to be more valued and since visitors did not face high levels of congestion.
Fifth, the findings reveal that both satisfaction with the lakes and with the lake destination have a significant impact on loyalty regarding these destinations, suggesting that the management of these places should consider both the lakes themselves and the environment surrounding them. It is observed that satisfaction with the lake destination has a much stronger impact on loyalty towards the destination, than satisfaction with only the lake itself. This underlines even more the importance of the territory around the lake and suggests that the poor environmental state of the lakes may be overcome by good perceptions regarding other components of the lake destination.
The findings of this study also provide important practical implications for planners and managers of lake tourism destinations. Guaranteeing water quality is of major relevance, not only for tourism, but is fundamental for the sustainability of the whole destination. In this sense, the water quality indexes of the lakes can be helpful for local authorities to understand the present status in this context and taking measures towards improving lakes water quality and its protection. The authors reinforced the value of the indexes in measuring water quality and in taking preventive steps to prevent further degradation [
27].
Moreover, to move towards sustainable tourism development in the destination, there is a need to guarantee all aspects of sustainability, including favorable environmental state of the lakes. Therefore, new, and innovative approaches are needed for lake destination management, which will incorporate sustainability aspects. The researchers [
62] mentioned various technical innovations for improving water quality in the lakes, such as improvements in land management, riparian plantings, constructed wetlands, lakebed treatments and water quality models, among others. Creating a good lake environment, encompassing pleasant scenery, good facilities on the lake shore and good accessibility to the lake, is of major importance due to the impact of the lake environment on satisfaction with the lake.
Despite the important theoretical and practical contributions of this research, some limitations can be identified. Hence, the geographical and temporal scope of the research was limited since the research model was only tested in a specific lake destination in Kazakhstan. The proposed model should be tested in other lake destinations to ascertain whether the hypotheses are confirmed in other contexts. The research was also carried out in a limited period, not including the whole year nor the period of highest demand. It would be of great value to conduct research during high season, when the visitors are more engaged in water-based activities and where higher use pressure may be felt due to the presence of more people and potential congestion.
This research area is relatively new in tourism, and more contributions are needed to better understand the lake destination perceptions, as well as its consequences. Nevertheless, this research, which provides insights into the impact of lake destination perceptions, including sustainability perceptions, both on satisfaction and loyalty towards lake destinations, provides useful guidelines to design appropriate strategies for managing and planning this kind of destinations.
