Over the last several decades, the world’s ecosystems have been changing to meet the ever-growing needs and demands for natural resources such as land, food, water, fuel, and minerals [
1]. As a result, the world’s ecosystems have been substantially and significantly damaged, remain overused, and their use can no longer be regarded as sustainable. This has led to the growing importance of conducting research on ecosystem services such as the benefits that humans derive from ecosystems that are critical for addressing sustainable development. Sustainability refers to the use of desired ecosystem services now and in the future, without creating short- and long-term declines in the natural resources and associated biodiversity [
2]. Nature conservation and conservation management strategies are now being widely recognized, but the relationships and/or interactions between the environment and development are not well understood. Environmental strategies today require investment in the conservation, restoration, and sustainable use of ecosystems and their resources to provide substantial ecological, social, and economic benefits [
2].
While many researchers have provided agendas for studying ecosystem services with the aim of promoting an understanding of the use and management of natural resources, the ecosystem services provided by wetlands is one emerging field that has been widely recognized in recent years [
3]. Despite global efforts in promoting wetland conservation since the signing of the Ramsar Convention on Wetlands in 1971, the area of the world’s wetlands still decreased by 35% between 1970 and 2015, and approximately 12 million km
2 of wetlands remain in the world [
4]. It is acknowledged that human sensitivities to the landscape have become an important element in the creation of wetland protection policies. A landscape that makes people feel the beauty of nature and has a healthy ecology can evoke many positive emotions and feelings in a person that then promote protective environmental behaviors [
5]. Furthermore, individuals who demonstrate a strong sense of attachment to specific natural resources or sites are likely to exhibit REBs [
6,
7,
8].
In Taiwan, the Wetland Law states that the sustainable and rational use of wetlands form the basis for the reasonable use of wetland ecosystem services [
9]. This law is generally regarded as being vague or hard to understand because as written, it allows for different interpretations to be made, which then contribute to uncertainty and a lack of understanding of the intent of the law by the public [
10]. However, the priorities that are considered important in wetland conservation areas are largely dependent on a stakeholder’s position regarding matters that they consider important at the time [
11]. In addition, wetlands that do not receive much public attention are often unregulated, forgotten, and likely to become degraded. Our emotions toward wetlands and associated environmental behaviors have a profound impact on the status of wetland management and quality of the wetland resources. Hence, it is important to understand the factors that connect the public’s preferences towards wetlands and how their attention towards site conservation can be affected.
Therefore, we sought to explore the relationships between landscape preference, place attachment, and REBs for the wetlands at GNP.
1.1. Responsible Environmental Behavior
Environmentally responsible behavior promotes the sustainable use of natural resources [
12] and has been called pro-environmental behavior in other studies [
13,
14,
15,
16]. People can demonstrate environmentally responsible actions at the individual [
12,
17] or public level [
17], or a person can either be actively committed to protecting the environment by being directly involved in environmental organizations or, indirectly, by contributing to environmental policies [
17]. REBs can either be individual or collective actions supporting environmental policies [
18]. Furthermore, REBs can be a general intent to protect the environment or targeted towards specific environmental issues [
13]. Environmentalism at the individual level tends to be more specific and involves the use of environmentally friendly products for personal or household use [
17]. People are more likely to engage in REBs at the individual rather than a more openly public level [
19].
Environmentally responsible behaviors are generally affected by a number of key factors such as environmental sensitivity [
20], conservation commitment [
21], attitude [
14], altruistic values [
22], belief [
23], and awareness [
22]. Environmental sensitivity is a precursor to environmental ownership and empowerment that lead to environmental citizenship [
24]. Without being sensitive towards the environment, one is less likely to have a desire or action to protect the environment. Environmental sensitivity is the predisposition for driving one’s interests towards learning about the environment or being concerned about it, taking actions that preserve the environment, and forming experiences that may become habits [
20]. Commitment to conservation and pro-environmental attitude directly influence REBs [
14,
21]. When people are environmentally sensitive, they are more likely to be attached to a place and demonstrate REBs [
25]. Environmental sensitivity is augmented with increased knowledge about the environment [
25]. People that interact with the natural environment regularly are more likely to exhibit a conservationist attitude [
14]. Furthermore, such regular interactions with the environment can potentially increase a person’s awareness of environmental disasters and their consequences; subsequently, this positively influences pro-environmental behaviors [
22].
Study results have shown that people can develop a strong bond with the place where they live [
26,
27], and this can be an important factor in determining how people will react in response to the environmental concerns of a specific place [
13,
28,
29,
30]. The extent of bonding with a place will affect how people negotiate with other stakeholders regarding the use of the resources in that landscape [
28]. However, it is important to note that the bonding relationship with a place is dynamic because it changes in response to other environmental, economic, and social changes [
27,
31]. Thus, this has a significant influence on a person’s landscape choice [
27]. Therefore, the following hypothesis is proposed:
Hypothesis 1. Landscape preference will positively influence REBs.
1.2. Landscape Preference
Landscape preference (LP) is a feeling produced by the continuous interaction between people and a landscape. It begins to become established through landscape perception, gradually develops into landscape cognition, and eventually generates preferences for different types of landscapes through subjective evaluation. In addition, LP involves having a long-term social or individual belief in the same value [
32]. In previous studies, the preference of people towards different types of landscapes [
33,
34]; floras [
33]; site moisture conditions [
27,
33]; demographic characteristics, including family size and education [
27,
33], gender, and land value [
35,
36]; and social factors such as the history and forms of past agricultural practices have been examined [
34]. A study related to river landscapes showed that they were highly correlated with landscape preference [
37]. Landscape preference is an important field of environmental psychology. The better an observer perceives the naturalness of a landscape, then the closer a natural landscape will be to what the observer believes its natural state is [
38].
People have a greater preference for advertisements using landscapes with a natural background rather than urban landscapes [
33]. Research findings also reveal that humans are predisposed towards natural settings with green landscapes and water features compared to artificial settings. This predisposition towards natural settings probably developed over time as humans evolved with nature in natural settings. Greener areas tend to be rich sources of water and food, and, from an evolutionary standpoint, humans are predisposed towards preferring green spaces [
39]. However, this contradicts the findings of other studies that suggest people that lived for extended periods of time in dry landscapes still prefer green landscapes [
40]. Alternatively, it has been claimed that people have negative preferences towards landscapes similar to those where they grew up [
27].
Although green mesic landscapes and savannas consume more water than xeric landscapes, people still prefer high- compared to low-water use landscapes [
27].
Savanna-type landscapes appear to be a universally preferred landscape across many cultures. They are characterized by grasslands interspersed with trees growing sparsely or in large clusters [
33,
41]. While education is a key to environmental sensitivity [
25], it does not appear to enhance an individual’s preference towards xeric low-water-use landscapes. On the other hand, it has been discovered that people prefer water-wise rather than high-water-use designs [
42]. Furthermore, males prefer landscapes that are drought tolerant and low maintenance [
35,
36,
40]. Studies [
43] also revealed that landscape preference influences place attachment; for example, remote sensing techniques could potentially provide additional data on characterizing wetland landscapes that influence human perceptions and behaviors [
44]. Hence, the following hypothesis is proposed to investigate this phenomenon:
Hypothesis 2. Landscape preference will positively and substantially affect place attachment.
1.3. Place Attachment
The concept of place attachment (PA) explains the connection between an individual and a specific place [
45]. Other researchers [
46,
47,
48,
49,
50] suggest place attachment can be any positive or negative relationship that a person developed with a location that creates an emotional bond with that place. Furthermore, place attachment can also be regarded as an individual’s experiences or memories that are associated with people, environment, and the land where those experiences occurred [
51].
Place attachment is a multidimensional construct that involves the interaction of people, processes, and places [
50]. From a person’s perspective, place attachment often can occur at individual and group levels. It involves psychological processes that relate a person’s affective, cognitive, and behavioral components to a place or places [
50]. Place aspect relates to the nature and specific elements of the place that have become objects of the attachment formed between a person and a place.
There are four key sub-dimensions of place attachment, which include place identity [
52,
53,
54], place affect [
52,
55], place social bonding [
56,
57], and place dependence [
53,
58]. Place identity refers to a symbolic or affective attachment to a place that a person has developed over time and that may lead to a sense of belonging and/or purpose that gives meaning to someone’s life. As such, place identity can be described as a component of self-identity [
59] that enhances self-esteem [
60] and increases the feelings of belonging to a community and/or specific environment [
45,
61]. The effect of place affect is the emotional bonding with a place that can play a vital role in how individuals practice natural resource management and politics [
50,
62]. People typically use places to protect and enhance their self-identity [
59], and they may conceptualize a resource in different ways depending on how they define themselves.
Place social bonding refers to the experiences derived from the social interactions at a certain place, which helps foster a sense of group belonging [
51]. Individuals develop social bonds with other people through place interaction, and it is this natural environment that leads to higher levels of attachment [
46,
57]. Place dependence is related to the functionality of a place that reflects the importance of a resource providing amenities necessary for desired recreational activities [
63]. This functional attachment is embodied in an area’s physical characteristics and, therefore, has an ongoing relationship with a particular setting. A history of repeat visitation enhances place dependence, which may lead to place identity [
64].
Research on place attachment has been growing, especially in the environmental psychology, natural resource management, environmental education, and tourism sectors [
8,
13,
46,
57], and considerable theoretical and methodological advancements have been made regarding place attachment [
46]. Furthermore, a measurement profile for place attachment, which includes place dependence, place identity, and lifestyle constructs has been established [
58,
65]. In a number of studies [
29,
30,
66,
67,
68], the effects of place attachment on REBs were examined. In some studies [
66,
69], place attachment was used as a single general construct, while others [
57,
67,
68] considered place attachment as a multidimensional construct and used place identity [
30,
67,
68], place dependence [
67,
68], and social bonding [
29,
57] as place attachment sub-dimensions. Furthermore, there was evidence indicating the need for a better understanding on conservation efforts and pro-environmental behaviors in regard to neglected wetlands [
70].
Weak and negative or null relationships between place identity and pro-environmental behaviors have been revealed [
29,
30]. These results indicate that more attachment to a place can potentially lead to a low level of pro-environmental behavior. However, others argue that place identity can influence pro-environmental behavioral intentions [
67,
68]. Environmentally responsible behaviors have been characterized as being low or high effort, and place dependence was shown to be negatively related to high-effort pro-environmental behavioral intentions [
29]. In contrast, a significant and positive relationship between place dependence and intentions to preserve the environment has been shown [
67]. Although these studies considered short-term visitors as research participants, one study is based on a small sample size from a regional Australian town [
29], whereas another considered a densely populated tourist area in Taiwan. It is still not clear what caused these different relationships between place dependence and pro-environmental behaviors among tourists in these very different locations [
67].
Similarly, place effect is another dimension of place attachment that has been used for testing the relationship between place attachment and REBs. Place effect had a significant relationship with both low- and high-effort pro-environmental behaviors [
29]. This suggests that emotional attachment is the only construct which has a significant and positive relationship with pro-environmental behaviors, indicating that when people are emotionally attached to a place, they are ready to be engaged at any level of pro-environmental behavior. A strong positive relationship between place social bonding and high-effort pro-environmental behaviors has been shown [
29], but the data are negatively related to low-effort pro-environmental behavioral intentions. Given that the findings in these studies are inconclusive, we cannot ascertain or generalize whether and how place identity, place dependence, place effect, and place social bonding would influence pro-environmental behaviors. Thus, further investigation is needed to gain insight into this domain.
Specifically, in the field of tourism research, place attachment is often conceptualized as the degree of value and identification an individual feels with a particular natural place, including the emotion of the place and the meaning and feeling that the place provides to the individual [
64,
71]. Several tourism scholars have approached place attachment as an antecedent to REBs [
8] or pro-environmental behaviors [
13]. In prior studies, the effects of place attachment on REBs among young hikers that participated in a natural resource work program and visitors to national parks were investigated; however, no studies have been conducted to address these issues specifically with wetland tourists. Hence, the present study seeks to fill this research gap by examining these relationships among wetland tourists, and we propose the following hypothesis:
Hypothesis 3. Place attachment will positively influence REBs.
