Socio-Cultural Valuation of Urban Parks: The Case of Jose Rizal Plaza in Calamba City, The Philippines

: The socio-cultural value of urban parks has rarely been studied, and this could be why they are undervalued and not given significant attention in city planning. This study presents the socio-cultural valuation (SCV) of the ecosystem services (ES) and disservices (EDS) of the Jose Rizal Plaza in Calamba City, The Philippines. Stakeholders were interviewed to assemble a list of the park’s ES and EDS. An online survey was then conducted to examine how stakeholders assign values to the park ES and EDS. Finally, the configuration of conditions leading to the assigned values was analysed. The results suggest that respondents value the park’s ES more than they worry about its EDS. They value cultural ES the highest, while they are most concerned with psychological EDS. The Fuzzy-set Qualitative Comparative Analysis (fsQCA) revealed that visiting the park is necessary for a high valuation to ES. For EDS, these are: not knowing the previous land use in the area and visiting the park. Overall, the paper concludes that SCV is an effective way to assess the value of urban parks, and fsQCA could aid in determining the combination of conditions leading to these values.


Introduction
Urban parks are semi-natural or human-made ecosystems comprised of a network of public open and green spaces in cities. They are known to provide a range of environmental, social, and economic benefits [1,2]. One way in which these benefits have been conceptualised is the concept of Ecosystem Services (ES) [3,4]. The ES concept became widely recognised as a tool for socio-ecological assessment of ecosystems after the Millennium Ecosystem Assessment (MEA) in 2005. The MEA suggested four categories of ES-provisioning, regulating, supporting, and cultural. Provisioning ES are direct ecosystem products such as food, timber, and water while regulating ES are the benefits that we get from the regulation of ecosystem processes such as climate regulation, natural hazard regulation, water purification, and pollination. Supporting (or Habitat) ES highlight the importance of ecosystems to provide habitat and to maintain genetic diversity. Cultural ES are the non-material benefits that people obtain from ecosystems through spiritual enrichment, cognitive development, reflection, recreation, and aesthetic experiences [5,6]. While considered a breakthrough in the study of the human-nature relationship, one of the critiques of the ES concept is that it gives the impression that nature only produces benefits [7]. It does not seem to acknowledge the presence of ecosystem disservices (EDS) or the ecosystem functions that are perceived to have a negative impact on human well-biggest lake in the country (Figure 1). The city is politically subdivided into 54 "barangays" (villages) [29]. The Jose Rizal Plaza is a 7 ha park located at Barangay Real in Calamba City. It was built in 2011 and houses one of the tallest monuments of Dr Jose Rizal, the Philippines' national hero. As of January 2020, the park has the following amenities: football field, gardens, lounge (which has not been opened yet to the public), and activity area (used for Zumba classes, jogging, and different events) (Figures 1 and 2). A coliseum, shaped like a clay pot or "banga" (where the city derived its name), is also being constructed in the area.

Conceptual Framework
Brown's (1984) work on the concept of value was chosen as the conceptual framework as it is arguably the basis of the idea of SCV ( Figure 3) [11]. He proposed that held values lead to the expression of assigned values through preferences and the relationship between the individual and the object being valued [11]. Socio-economic variables were assessed in the study since individuals perceive and therefore value ES differently according to their socio-cultural backgrounds [5,15,30]. Since urban parks are common resources, the respondents' social value orientation (SVO) was also measured to represent their concern for others when making decisions about allocating resources [31]. Environmental knowledge, awareness, perception, and behaviour were assumed to influence people's preferences and their relationship to nature.

Online Survey Structure and Administration
An online survey was utilised to undertake the SCV. The questionnaire consisted of five sections: (1) park use; (2) environmental knowledge, perception, and behaviour; (3) social value orientation; (4) valuation of ecosystem services (ES) and disservices (EDS); and (5) socio-economic characteristics (Table 1). A copy of the questionnaire is in the Supplementary Materials.
The first section asked the respondents how they utilise the park-if they had visited it before and the frequency and purpose of their visits. In the second section, environmental knowledge was measured through common environmental concepts and the environmental laws in the Philippines. Respondents were asked to choose from a group of words, the environmental concepts described in seven statements [32,33]. The total number of correct answers was used to represent the respondents' knowledge of environmental concepts. They were then asked to gauge how much they knew about the three primary environmental laws in the Philippines through a Likert scale from 0 (practically no knowledge) to 3 (a lot). The respondents' environmental perception was assessed by asking them how they think local environmental issues have become since they have lived in Calamba City [34,35]. They were asked to choose from a Likert scale from 1 (much worse) to 5 (much better). They were also given a choice to answer 0 if they thought they did not have enough knowledge to provide a rating. Finally, environmental behaviour was measured by asking the respondents how frequent they practised nine positive environmental behaviours [36,37]. They were asked to rate each action from 1 (never) to 5 (always). They were allowed to answer 0 if they wanted to skip a number. The scales used to measure the knowledge of environmental laws, environmental perception, and environmental behaviour had high levels of internal consistency (Cronbach's alpha of 0.878, 0.829, and 0.813, respectively). To represent held values, the respondents' social value orientation (SVO) (i.e., the magnitude of their concern to others when it comes to allocating resources) was measured in the third section using a tool developed by Murphy and Ackermann (2013) [31]. Respondents were asked to imagine being paired with another person unrelated to them. They were then asked to choose one resource (cash) allocation between them and the other person out of nine options six times. The responses were then transformed into a degree score determining the respondents' SVO. A competitive individual is someone who aims to maximise the difference between what they have and what the other person has. Individualists aim to maximise resources for themselves. A prosocial values the equality of resource distribution, while an altruist endeavours to maximise others' resources or benefits [31].
In the fourth section, the respondents were asked to rate the importance of the ES and the worry they have for the EDS of the park using a continuous scale slider from 0-10 (with one decimal place) [38,39]. The ES and EDS that were included in the survey came from the benefits and disbenefits cited by the respondents during key informant interviews that were carried out in the initial stages of the research. The ES were categorised based on the Millennium Ecosystem Assessment classification [3]-provisioning, regulating, supporting, and cultural, while the EDS from Lyytimäki and Sipilä (2009) [8],   [9], and Von Döhren and Haase (2015) [10]. Additional ES types, namely, economic, security, and non-use (an aggregation of existence, option, and bequest ES), were added based on the ES categorisation by Forest Foundation Philippines et al. (2019) [40] and Kati and Jari (2016) [41]. The values that the respondents assigned to ES (statements 1 to 36) and EDS (statements 37 to 44) were averaged. The fifth section summarises the respondents' socio-economic characteristics.
The survey was administered online through the Qualtrics Core XM Survey Tool from April to July 2020. The link to the survey was distributed using social media posts and emails. The survey data from Qualtrics was exported as an SPSS data set for analysis.

Data Analysis
Answers to the fifth section of the questionnaire (socio-economic characteristics) were analysed using descriptive statistics first to summarise the demographics of the respondents and to categorise them according to the stakeholder groups that were identified through key informant interviews with relevant city office departments: the city office and its employees; the businesses around the park (specifically in Barangays Real and Halang); students; and the residents from all barangays (near and far from the park). As suggested by key informants, residents living within a 4 km radius from the park were considered near, while those beyond were considered far. The first four sections were then subsequently analysed. The mean values given to ES and EDS were not normally distributed according to a Shapiro-Wilk's test [42] (p < 0.05) so a Mann-Whitney U test [43] was used to determine if there were significant differences between the two. The mean values assigned to the different types of ES and EDS were also not normally distributed so Kruskal-Wallis tests [44] were performed to compare them. Finally, except for the ES values from businesses, Kruskal-Wallis tests were also used to investigate if there were significant differences in the values assigned by each stakeholder group to the different types of ES and EDS. One-way analysis of variance (ANOVA) was applied to the values given by businesses, since the data follow a normal distribution (p > 0.05). All the analyses were accomplished through IBM SPSS Statistics for Windows, Version 26.0, New York, NY, USA except for the Fuzzy-set Qualitative Analysis, which was run through the fs/QCA software Version 3.1b, Irvine, CA, USA [45] (details provided in the Supplementary Materials).

Socio-Economic Characteristics
A total of 1234 opened the questionnaire through the Qualtrics link, but only 675 completed the survey. More than half of the respondents (55.85%) found out about the survey from a colleague, friend, or a relative, and 30.07% found it through social media posts. The rest were informed by a city or a village office employee and the author. The socio-economic characteristics of the respondents are in Table 2. In general, the respondents were prosocial (78.37%) and individualistic (19.41%). Few were altruistic and competitive (2.22%). A considerable percentage of the respondents are college students (42.67%), residents from barangays near the park (28.30%), and residents far from the park (12%). Less than 15% are owners or employees of businesses in Calamba City, barangays closest to the park, and city office employees.

Park Use
Almost all the respondents (96.4%) have visited the Jose Rizal Plaza. When asked how frequently they visited the park in the previous year, the majority of the respondents reported their visits per year (53.3%), while 32.7% and 14% reported their visits per month and per week, respectively. Those who reported their visits per year came to the park from 0 to 20 times, with a mean of 3 (SD = 2.5) and a mode of 1. Those who reported their visits per month visited from 1 to 10 times, with a mean of 2.4 (SD = 1.6) and a mode of 1 and 2, and those who reported their visits per week came there from 1 to 7 times, with a mean of 3 (SD = 1.8) and a mode of 2.
A little more than half of the respondents visit the park to watch or participate in events (50.7%) or to relax or unwind (48.7%) ( Table 3). Other reasons mentioned by the respondents include going to the Christmas carnival, eating, family bonding, attending meetings, school activities, and strolling. The majority of the respondents (60.74%) do not know the previous land use in the area where the park is built. Out of the 265 who said they knew the previous land use, only 177 (66.79%) answered correctly-an idle or vacant lot, grassland, or plant stalls.

Environmental Knowledge, Perception, and Behaviour
For environmental concepts, the respondents had an overall mean score of 4.28 (SD = 1.72). The respondents got more correct answers for concepts such as climate change (88.15%) and green spaces (81.04%), while they got the least correct answers for urban sprawl (33.78%). The respondents shared that they have "little" to a "fair" amount of knowledge about the three major environmental laws in the Philippines. According to the respondents, environmental conditions in Calamba City have gotten "worse", except for water shortage and the quality of public, green, and open spaces, which has "stayed the same" and has gotten "better", respectively. Overall, the respondents encourage people to protect the environment "often", while they "never" join or donate money or time to environmental or conservation organisations.

Valuation of Ecosystem Services (ES) and Disservices (EDS)
The respondents assigned a mean value of 7.25 (N = 675, SD = 2.1) to ES and a mean value of 5.85 (N = 675, SD = 2.4) to EDS. A Mann-Whitney U test [43] confirmed that the median of ES means (7.78) was statistically significantly higher than the median of EDS means (5.95), U = 150765.5, z = −10.76, p < 0.001.

Ecosystem Services (ES)
The ability of the park to provide a place for enjoyment and spending free time had the highest mean out of all the ES (N = 675, M = 8.32, SD = 2.23), while the ability of the park to serve as a water recharge area had the lowest (N = 675, M = 6.16, SD = 3.08).
A comparison of how each stakeholder group values the different types of ES is in Figure 4. All the stakeholder groups except for city office employees assigned the highest values to cultural ES, followed by non-use, economic, security, and regulating ES. City office employees assigned higher values to non-use than cultural ES, followed by economic, security, and regulating ES.   (Dunn's (1964) procedure with a Bonferroni correction) confirmed statistically significant differences between economic (mean rank = 936.62) and health (1035.28) (p = 0.006) and psychological EDS (1067.11) (p < 0.001).
A comparison of how each stakeholder group values the different types of EDS is in Figure 5. All the stakeholder groups assigned higher values to psychological EDS, followed by economic and health EDS. Kruskal-Wallis H tests revealed that there was no significant difference in how barangays closest to the park value the different types of EDS, χ 2 (4) = 0.408, p = 0.816. It was the same for barangays near the park, χ 2 (2) = 4.161, p = 0.125; businesses, χ 2 (2) = 1.051, p = 0.591; and city office employees, χ 2 (2) = 4.164, p = 0.125. In contrast, there was a significant difference in how the barangays far from the park valued the different types of ES, χ 2 (2) = 6.086, p = 0.048. There was also a significant difference in how college students value the different types of ES, χ 2 (2) = 7.021, p = 0.030. Pairwise comparisons using Dunn's (1964) procedure with a Bonferroni correction revealed a statistically significant difference in the values assigned by college students to economic (mean rank = 401.90) and health ES (440.31) (p = 0.031).

Valuation of ES and EDS
Results suggest that respondents value the park's ES more than they worry about its EDS. Overall, respondents value cultural ES the highest and the regulating ES the lowest. Zhang et al. (2020) [47] and Schmidt et al. (2016) [48] also found that cultural ES are the most valued services in urban green spaces in China and Scotland, respectively. Regulating ES might have been valued the least because respondents understand the park experientially and not functionally [49]. In a study by Zagarola et al. (2014) [50], they found that cultural ES of watersheds were the most understood, while the regulating ES were the least understood by people.
While there were no statistically significant differences in how each stakeholder group valued a specific type of ES, it is worth mentioning that all ES types, except for cultural ES, were valued the highest by barangays closest to the park. These findings suggest that people's appreciation of the park's ES is related to their proximity to the area.  [52]. Cultural ES were valued the highest by barangays far from the park, suggesting that the appreciation of this type of ES extends beyond the proximity to the park. Unexpectedly, economic ES were valued the lowest by businesses. It might have been because the economic ES that were included in the survey were not directly related to a possible increase in the revenue of the businesses. It is important to note that businesses were not able to contribute to the list of ES and EDS of the park since they refused interviews during the early stages of the research. It was an advantage that at the initial stages of the research, two methods were used to create the list of park ES and EDS. First, the key informants were asked directly what benefits and disbenefits they think the park has. To ensure not to miss any ES and EDS, common park ES and EDS from the literature were compiled, and respondents were asked if they think the park has them. These findings highlight the importance of involving the different stakeholder groups in developing a list of ES and EDS for a valuation survey [53,54]. All the stakeholder groups, except for city office employees, assigned the highest value to the cultural ES. The city office employees assigned the highest value to non-use ES. All the stakeholder groups assigned the least value to the regulating ES. Based on the results, barangays closest to the park and city office employees value each ES type equally, while other stakeholder groups favour cultural ES over regulating ES and other ES types.
For the EDS, the respondents were most concerned with psychological EDS and least worried about economic EDS. Psychological EDS can be considered very similar to cultural ES as they are also intangible and sometimes abstract. There were also no statistically significant differences in how each stakeholder group value a specific type of EDS. Still, it was found that all the types of EDS were valued the highest by barangays closest to the park. This result suggests that, similar to ES, people's concern about the park's ES is related to their proximity to the area. All the stakeholder groups assigned the highest value to the psychological EDS and the least value to health EDS. Based on the results, all the stakeholder groups, except for barangays far from the park, value each EDS type equally.

Conditions Leading to High ES and EDS Values
The top two configurations of socio-economic characteristics with the highest consistencies in causing a high valuation to ES and EDS were the same-not having a prosocial orientation and being a local resident and not having a prosocial orientation, living near the park, and not owning a house. These findings demonstrate that while exposure to green areas could influence the adoption of prosocial behaviours [55,56], this prosocial orientation does not, in turn, lead to the high valuation of the park's ES or even deep concern about its EDS. A person does not need to have a prosocial orientation to appreciate the park's ES highly and worry much about its EDS. Moreover, the presence of conditions such as being a local resident and living near the park suggests the influence of place attachment on how respondents gauge the importance of ES and their concern for EDS. Place attachment is a person's unique connection with nature or a certain area, which develops when the place can supply or support their demands or intentional use and activities. Studies have shown that place attachment increases people's concern about ecological values [41]. Not owning a house appears to be sufficient in causing a high valuation to ES and EDS when combined with a non-prosocial orientation and living near the park. A related study by Gashu et al. (2020) [57] found the opposite-owning a house positively influences the perception of the presence or absence of green infrastructure ES. However, it did not discuss how it can combine with other socio-economic characteristics. Another condition appearing in both solutions for high ES and EDS is the high educational level. Several studies support that people with higher educational attainment tend to value ES more [53,58,59]. They are also more willing to use green infrastructure and participate in urban green infrastructure development [57].
Results from the fsQCA indicated that visiting the park is necessary to cause a respondent to value the ES of Jose Rizal Plaza highly. This result suggests that a person needs to have a direct experience with the park to appreciate its ES. Visiting the park can also combine with not visiting other parks, not frequently visiting the park, and knowing or not knowing the previous land use in the area to cause the outcome. When it comes to the high valuation to EDS, two conditions were necessary-not knowing the previous land use in the area where the park is built and visiting the park. This result suggests that direct experience is also necessary to assign worries to the park EDS and that knowledge about the previous land use does not influence the high valuation to park EDS. There are no previous studies to directly compare these results with as this study pioneers the use of fsQCA in determining the configuration of conditions that lead to a high valuation to ES and EDS. However, in a study by Zhang et al. (2016) [60], they also concluded that a direct experience with a land use could result in high recognition of its ES. Swapan et al. (2017) [52], on the other hand, found that the frequency of visits to an urban park influences users' perception of the importance of its ES.
The configurations of environmental knowledge, perception, and behaviour leading to the high valuation of ES were the same as that of the EDS. In other words, the same combinations of conditions lead to an increased appreciation for the park's benefits and a deep concern for its EDS. Results suggest that those who believe that environmental conditions in the city are getting worse and admit that they have not been practising proenvironmental activities cause them to appreciate the current park ES and worry that park EDS will worsen. Duan [14] also asserted that environmental knowledge increases the importance value that the public assigns to ES. The other two configurations suggest that the power of knowing environmental concepts in causing a high valuation to ES and EDS is equivalent to having knowledge of environmental laws and practising pro-environmental activities.

Limitations and Future Studies
While the survey has outstanding value, it also has several limitations. First, since it was only administered online because of the pandemic, the respondents were limited to those who can use mobile phones, tablets, laptops, or computers and those who have access to the internet. Thus, it might not have been able to capture a representative sample of the stakeholders of the park. Second, because the survey was conducted when the residents of the city were restricted to visit parks due to the pandemic, their opinions about ES and EDS and their willingness to contribute might have been skewed. The third set of limitations is typical of self-administered surveys-questions could be misinterpreted, and answers could exclusively be stated preferences and not how they are in real life. Future SCV studies should always aim to represent as many stakeholder groups as possible and involve them in identifying ES and EDS in the ecosystem under study. Deliberative forms of value elicitation could also be explored to gain insight into how interaction could impact assigned values to ES and EDS.

Survey Value
The academic value of the survey comes from filling in the gaps of previous sociocultural valuation studies and the novel way of analysing conditions that cause a high valuation to ES and EDS. It provides in-depth insights about a large number of stakeholders who engage with the park-findings that could then be compared with other studies in the literature. The survey involved as many types of stakeholder groups as possible, a characteristic that is usually missing in previous socio-cultural valuation studies [23,62]. EDS, which are typically overlooked in valuation studies [30], were included in the assessment. Additionally, stakeholder groups were involved in creating the list of the park ES and EDS through key informant interviews that were undertaken at the initial stages of the study. Some studies in the past only used predetermined lists from literature [23,51]. For the analysis, it was the first time that fsQCA was used to analyse conditions affecting the valuation to ES and EDS. It proved useful as it highlights that the assigned values to ES and EDS are not caused by individual factors, but a complex combination of conditions. Another value of the survey is that it was able to capture the values assigned to the ES and EDS of an urban park during a global pandemic, which limited people's ability to visit such important urban resources.
For the city, the survey results provided baseline information on how residents utilise the park and which ES and EDS they value most. The survey provided insights as to which amenities they could maintain and enhance and which to improve. Results of the survey also inform the city about the importance of making sure that the park is accessible to residents, as a direct experience with the park enhances the residents' appreciation of its ES and EDS. The survey also provides information on the combination of conditions leading to a high valuation of ES and EDS. This information could help the city develop strategies to improve residents' appreciation of parks and even their participation in initiatives related to green spaces or urban green infrastructure.
