The world has been experiencing a critical period of urbanization in its history, with continued urban growth contributing to human population densification and a significant loss of green spaces (Lin et al. 2015, Munyati and Drummond 2020). Urban green spaces are the main natural elements in cities and play an essential role in sustainable urban growth through the provision of ecological, economic, and social benefits (Xu et al. 2020). Previous studies have argued that urban green spaces, including parks, gardens, children’s playgrounds, green roofs, residential green spaces, streetside greeneries, green areas, and other open natural areas, have intangible cultural properties (Ko and Son 2018). Urban green spaces generate a wide range of benefits, called ecosystem services (ES), such as biodiversity, air quality improvement, rainwater regulation, and emissions minimization (Bolund and Hunhammer 1999, Bowler et al. 2010, Chan et al. 2012a, Faehnle 2014, Riechers et al. 2018, 2019). Quality of life, including health and well-being in cities, largely depends on the ES that urban green spaces provide. For ensuring the proper delivery of ES, multifunctional, accessible, and heterogeneous green spaces throughout urban areas are essential (Gomez‐Baggethun et al. 2013). Successful protection of green spaces in accessible urban locations requires the development of policy and management strategies with national support and the involvement of local people and managers (Andersson et al. 2015).
In Bangladesh, more than 35% of the population lives in urban areas (World Bank 2016). The urban population in this country tripled from 1990 to 2019 (https://data.worldbank.org/indicator/SP.URB.GROW?locations=BD, cited in Dewan et al. 2021). Rapid urbanization is challenging for developing countries like Bangladesh (Rana 2011) because it causes pressure on social, environmental, and economic well-being (Zinia and McShane 2018) and a sharp reduction in natural greenness (Rai et al. 2017, Dewan et al. 2021). For instance, urban houses in this country are of poor quality and mostly built on illegally occupied land, resulting in a lack of the infrastructure necessary to protect residents from disasters and other adversities (Ahammad 2011). This is especially true in Dhaka, Bangladesh’s capital city, which is burdened with an annual population growth rate of 3.5% (BBS 2015). Dhaka is located at 23°42′ N and 90°22′ E on the eastern banks of the Buriganga river, with a highly dense population of 30,551 people/km² (BBS 2015). Rapidly growing, disorganized urbanization in Dhaka city has caused congestion and contributes to unhealthy lifestyles (Rahman and Zhang 2018). Furthermore, the rise of Dhaka city comes with a loss of green areas (Chowdhury and Faruqui 1989, Byomkesh et al. 2012). Urban management strategies of Bangladesh mainly focus on disaster and climate change management because the country is frequently affected by disasters (Dewan et al. 2021). However, inhabitants’ needs for green space and its management are often ignored (Rahman and Zhang 2018).
ES are considered a helpful doorway for managing nature, such as green space, in cities (Andersson et al. 2015). The Millennium Ecosystem Assessment (MEA) explained ES as the benefits people receive from the ecosystem (MEA 2005). These include provisioning services (e.g., food, water), regulating services (e.g., climate regulation), cultural services (e.g., recreational, aesthetic), and supporting services (e.g., soil formation). The MEA defines CES as “nonmaterial” benefits that people derive from ecosystems through “spiritual enrichment, cognitive development, reflection, recreation, and aesthetic experiences” (MEA 2005: 40). In this study, we use the definition of CES derived from Russell et al. (2013: 475) as “ecosystems’ contributions to human well-being mediated through non-material processes (e.g., the mind or culture).” This definition expressly includes direct experiences of nature, and the benefits are understood through human cognitive perception. Human–nature interactions are made sustainable through CES because CES in some way accommodates ecological conservation outcomes, human preferences, and values (Chan and Satterfield 2015, Arias‐Arévalo et al. 2017). Research on CES is considered to move the process of sustainable development forward by identifying and valuing CES (Chakraborty and Gasparatos 2019, Chakraborty et al. 2020) experienced in cities, understanding the way urban green spaces motivate stewardship and public participation, and assessing how CES can be included in policies and development strategies (Chan et al. 2012a, Andersson et al. 2015).
Solutions to ecological problems are generally implemented by decision makers in a “top‐down” manner. Therefore, a grassroots perspective from Dhaka residents is needed because previous studies show that experts’ opinions on CES differs from laypeople’s opinions (Nahuelhual et al. 2016, Riechers et al. 2017, Russel and Turnpenny 2020). Taking these views into account, we aimed to highlight residents’ perceptions on the importance of CES and their views on how best to manage such services. Analysis of resident perceptions in this way is minimal in the literature, especially in the Global South. Thus, we explored three research questions: (1) what importance do urban residents place on aspects of the green space CES, (2) what characteristics of residents are associated with their perceptions about the CES, and (3) what are residents’ perceptions about how CES can be most effectively managed?
Current trends suggest that green spaces in cities like Dhaka will continue to meet significant pressure in the face of conflicting demands for land. Understanding how residents perceive the importance of CES and how they think CES should be managed holds great promise for informing sustainable urban development that preserves and expands green spaces.
In Dhaka city, urban green spaces include rooftop gardens, parks, gardens, community gardens, and green walls (Zinnia and McShane 2018). Urban green spaces have special significance because they provide cultural services to urban residents (Riechers et al. 2019). We reviewed the literature on CES provided by different urban green spaces from different parts of the world and found that different types of green spaces provide different CES, and some of the CES are space‐specific (Table 1). For instance, urban parks provide CES that include recreation and natural awareness, gardens that offer recreation and learning, and historical places that support cultural heritage.
CES is still poorly explored, particularly in urban areas, but is increasingly required for humans’ welfare (Radford and James 2013). Previous CES research employed the term “cultural services” either without differentiating between different types of green space and respective services offered or focusing on single examples, such as “recreation and tourism.” There is limited understanding of the importance of a whole range of urban green CES from the urbanites’ perspective (see exceptions by Riechers et al. 2018, Shi et al. 2020), especially in the Global South. Urbanites from varied social backgrounds perceive nature based on their cultural values and beliefs (Faehnle et al. 2014). Respondents’ social background and green space visiting frequency are major concerns when trying to understand the valuation of CES (Riechers et al. 2019). Urbanites are very connected to CES provided by ecosystems. Urbanites attribute different cultural values and figurative meaning to nature. Park visitors may, for instance, use the term “diversity” without scientific knowledge of biodiversity concerning the number of species, richness, etc. (Voigt and Wurster 2015). Instead, the term is used to articulate that they value the beauty of urban green space and the importance of protecting it from deterioration. Previous research has also identified a connection between CES, public engagement, and sustainability (Colding and Barthel 2013, Andersson et al. 2014, Gould et al. 2014, Chakraborty et al. 2020). Individuals and communities prefer to support management actions when those actions improve CES (Dendoncker et al. 2013, Andersson et al. 2015). Hansen and Pauleit (2014) suggested combining green space and ecosystem services approaches with development strategies that capture complex human–nature relationships in urban regions and that support policy objectives such as social cohesion.
Further, the study by Pauleit et al. (2019) suggested context‐sensitive development of urban green space that reflects the diversity of residents’ demands and practices concerning urban green spaces. Urban management often lacks the inclusion of citizens’ perceptions or participation in management concepts, planning, and implementation (Ahmed et al. 2019). Previous research on managing urban green space has often considered ecological and economic benefits (e.g., Zinia and McShane 2018, Sun et al. 2019). However, the incorporation of social and cultural services from urban green space into the decision‐making process lags far behind (Shi et al. 2020). Therefore, our study’s contribution is to address the gap concerning cultural services offered by green spaces and to do so by analyzing residents’ perceptions.
To date, CES research has centered primarily on market services such as tourism and entertainment, and such assessments have primarily used monetary estimation (Cheng et al. 2019). However, in recent years, CES researchers have started using non-monetary methods, owing to the difficulty of monetizing intangible benefits arising from highly diverse green spaces in the presence of complex social factors (Christie et al. 2012, Gómez‐Baggethun et al. 2013). Non-monetary methods include, first, “revealed preference” (e.g., researcher observations, social‐media‐based analysis, document review) and second, “stated preference” (e.g., interviews with and/or surveys of local people; Cheng et al. 2019). The stated preference method allows residents to clarify their genuine perceptions and expectations about the CES (such as aesthetics, sense of place, education, and spiritual and religious aspects), and to suggest the values neglected by the monetary and revealed preference methods (Christie et al. 2012, Larson et al. 2019, Shi et al. 2020). The efficacy of stated preference approaches for the collection of CES data is further confirmed by a comparative analysis by Willcock et al. (2017). Thus, the stated preference method has generated increasing interest among CES researchers, and the “questionnaire method” (one type of stated preference method) is being used effectively to value CES in a non-monetary way (Cheng et al. 2019). Furthermore, studies have started to analyze variables that influence CES preferences and have suggested the need to understand the influence of individual variables (e.g., respondents’ gender) on perceptions of CES (Shi et al. 2020).
The evidence is clear that CES is vital to residents’ quality of life. However, the subject is often neglected by policy makers, and academic work that seeks to inform policy making is lacking. Countries usually have fewer policies to maintain CES, which results in difficulties in accounting for CES management (Pleasant et al. 2014). A review by Gould et al. (2019) revealed that only 27% of 232 published papers discuss CES’ links to decision making in general terms, 28% discuss specific influences on decision making, and the remainder mention the decision‐making connection briefly or not at all. We assessed residents’ perceptions of their own role and their perceptions of decision-makers’ and managers’ roles in managing (Zinia and McShane 2018) CES from specific urban green spaces.
Perception of the benefits of CES depends upon individual context and social factors (Braat and de Groot 2012, Riechers et al. 2018). However, in‐depth studies on assessing residents’ perception of CES within a management context are minimal. Thus, to fill this research gap, the present study aims to understand how the importance of CES is perceived by Dhaka residents, how this perception varies depending on residents’ background and visiting frequency, and the role of individuals and institutions in managing CES.
The urban development in Dhaka megacity has not been parallel with the fast growth of the city (BBS 2015, Rahman and Zhang 2018). Seventy-eight percent of this city’s green spaces were lost between 1975 and 2017 (Mundi 2018). According to Dhaka Structure Plan (2015), there are 41-46 parks and gardens in Dhaka city. Although Rajdhani Unnayan Kartipakkh (RAJUK), the authority responsible for developing Dhaka, planned for green space to make up 20% of the city, it has only 8% (Byomkesh et al. 2012). As depicted in Figure 1, Dhaka city is divided into two city corporations: Dhaka North City Corporation (DNCC) and Dhaka South City Corporation (DSCC). DSCC is divided into 10 zones; our study area lies in the zone‐1 area. DSCC governs 57 southern wards of Dhaka city. The total area of DSCC is 43.961 km², and zone‐1 covers 11.504 km². This zone covers ward numbers 15 to 21. There are 28 parks and 10 playgrounds in DSCC (DSCC 2020). The local government mainly takes the responsibility to manage the green spaces (e.g., parks, fields). However, previously it was reported that urban areas, including Dhaka, lack logistics and proper management strategies to manage green spaces efficiently (Heynen et al. 2006, Rahman and Zhang, 2018).
We selected the zone‐1 area based on field‐level observations, personal experiences, expert judgments, and literature review. The socio-demographic condition (population, education, gender, income level) were similar across the wards in zone‐1 (BBS 2013, DSCC 2020). We considered the presence of a variety of green spaces in this area, including lakes, parks, rooftop greeneries, and access to households for surveys during the selection process. Some zones (e.g., zone‐4, DSCC) in Dhaka city have no green patches at all (Rahman and Zhang 2018), so those zones were not considered for this study. Residents of zone‐1 provide a cross‐sectional overview of the residents who live in a privileged area of Dhaka city because they have access to green spaces such as Ramna Park, Dhanmondi Lake, green roofs, and household‐associated greeneries (Fig. 2). We needed to select a zone where green spaces are available, and, thus, user residents could perceive the role of those spaces and provide valuable information on CES provisioning and management.
To assess residents’ perception of the importance of CES and suitable approaches for managing green space, we used a questionnaire‐based stated preference method. This method supports analyzing social perceptions of CES in a consultative way and understands respondents’ prioritization of services (Castro et al. 2011, Ciftcioglu 2017).
The preparation work for questionnaire development and survey included (1) an extensive review of the relevant literature concerning how CES is conceptualized CES, (2) separate focus groups with, respectively, experts and non-specialists to improve the language and structure of the questionnaire, and (3) a pilot of the questionnaire survey with the residents from the study area (n = 39).
The final questionnaire focused on four points: first, respondents’ gender, income, educational background, and green space visiting frequency; second, the perceived importance of CES (Appendix 1); third, the importance of green space in providing CES; and fourth, the importance of CES management (and green space‐specific management) by individuals and organizations.
The CES categories were mainly adopted from the MEA (2005) to the context of Dhaka inhabitants. We substituted the CES category “traditional knowledge systems” with “natural awareness” and “cultural diversity” with “mental satisfaction” based on literature (Riechers et al. 2018) and preparatory questionnaire work. Previous studies have often substituted MEA CES categories. The categories are the bases of the MEA, and researchers develop other categories that incorporate CES concepts based on the needs of their specific study (e.g., Ko and Son 2018, Riecher et al. 2018, Shi et al. 2020). All the CES categories used in this study fit within the MEA concept of CES. Managerial entities of green space include individual, community, government, non‐government organizations (NGO), and international non‐government organizations (INGO). Further, based on Zinia and McShane’s (2018) recommendations on ES management in Dhaka city, we focused on respondents’ prioritization of the role of CES management by individual or collective effort (public collaboration with government/NGO/INGO). Five‐point Likert scales (from 1: not important to 5: very important) were used to collect data on the perceived importance of CES and CES management.
Data were collected between October 2018 and April 2019 using face‐to‐face questionnaire surveys of 405 households. Yamane’s (1967) simple random sampling formula was used to determine the sample size with ± 5% precision assuming a 95% confidence level. The sampling frame included residents (older than 18) of zone‐1 in DSCC. Surveys were conducted on various days of the week between 10:00 a.m. and 9:00 p.m. In our sample, 52.8% (n = 214) of the respondents were male, and the rest 47.2% (n = 191) were female. Most respondents held bachelor degrees (43.5%, n = 176). Regarding income, 44.7% (n = 181) of the respondents’ monthly income ranged from 25,000 to 75,000 Bangladeshi Taka (BDT; 84.95 BDT = US$1). Among the respondents, 47.7% (n = 193) reported visiting green space weekly (Appendix 2).
Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 26. The mean values of perceived importance of CES, green space for providing CES, the role of stakeholders, and importance of the individual and collective effort were calculated. We assessed relations between the perceived importance of 10 CES categories using bivariate correlations (Pearson’s r coefficient; see similar methods in Riechers et al. 2018). An independent sample t‐test was applied to understand the influence of gender on CES perception, and a paired sample t‐test was applied to investigate the difference between the respondents’ opinions (Shi et al. 2020) on CES management through individual and collective effort. One‐way analysis of variance (ANOVA; see similar methods in Shi et al. 2020) followed by posthoc Tukey’s tests were used to analyze the influence of respondents’ income, educational background, and visiting frequency on the perceptions of CES.
The overall assessment shows that the CES category recreation was perceived as most important, with a mean value of 4.03. The second rank was reached by the importance of aesthetics (3.91), followed by a sense of place (3.79). The least important CES was cultural heritage (2.45; Fig. 3). The mean importance across 10 CES categories was 3.33. Among green spaces, rooftop gardens were considered most important in providing CES (Fig. 4), with a mean importance value of 4.22, followed by green parks (4.06), and gardens (3.89).
Bivariate correlations between the perceived importance of categories of CES revealed several sets of services, including two prominent ones (Fig. 5). The first and most prominent set includes relationships between natural awareness, religious and spiritual, and cultural heritage, with each relationship achieving a Pearsons r greater than 0.60. Mental satisfaction, sense of place, and aesthetics form the second set of related categories (with Pearsons r values ranging from 0.30 to 0.60). Other sets with r values above 0.30 include education and learning and social cohesion or recreation, and inspiration and cultural heritage. Some other weakly bound sets (Pearsons r <0.30), including inspiration, religious and spiritual, and education and learning, were also revealed. Individual CES categories tended to correlate positively with each other, but some correlations between categories were negative (e.g., natural awareness and recreation).
The four important variables that elucidate the perceived importance of CES categories were gender, income, education, and respondents’ visiting frequency to green spaces. Results from an independent samples t‐test revealed that the importance of the CES categories recreation and education and learning was perceived differently by male and female respondents (Table 2). Compared with men, women more highly rated the CES categories recreation (mean rate 4.21) and education and learning (mean rate 3.71). The results from one‐way ANOVA with post hoc follow-up showed that respondents from the highest‐income group (more than 150,000 BDT) placed more importance on cultural heritage than respondents from lower income groups (Table 2). Respondents’ educational background significantly influenced their perception of the importance of the CES category recreation. Respondents who had never been to school rated the recreation category more highly (mean 4.36) than did respondents with other amounts of schooling.
In comparison to the above three variables (gender, income, and education), visiting frequency was found to significantly distinguish (p <0.01) respondents’ ratings of several CES categories: mental satisfaction, sense of place, recreation, education and learning, and social cohesion (Table 2). Daily visitors perceived recreation and social cohesion as the two most important CES categories (mean ratings of 4.57 and 4.37, respectively). On the other hand, yearly visitors rated mental satisfaction (mean 4.42) significantly higher than did respondents who visited more frequently.
Respondents from the study site prioritized the government’s role in managing CES, with a mean score of 4.29 (Table 3), over the individual’s, community’s, NGO’s, and INGO’s role. However, the community role attracted the second‐highest average rating (4.01; Table 3). Furthermore, 46.3% of the respondents indicated that the individual has an important role to manage CES. Results from paired‐sample t‐tests showed that respondents considered the collective role (public collaboration with government/ NGO/ INGO) significantly more important than the individual role in CES management for all types of green spaces except streetside greenery (Fig. 6). Green parks and rooftop gardens were perceived as the two most important green spaces to be managed collectively.
Our findings indicated that recreational services were perceived as the most important CES category, and aesthetics were the second most important (Fig. 3) (results similar to Jim and Chen 2006, Riechers et al. 2018). In contrast with other studies (i.e., Ponizy et al. 2017), our results showed the high stated importance of CES related to sense of place and social cohesion. Research by Bertram and Rehdanz (2015) conducted in four European cities (Berlin [Germany], Stockholm [Sweden], Rotterdam [The Netherlands], Salzburg [Austria]) demonstrated that the top three services provided by urban green space were related to physical and mental health and well-being. A similar result was found in studies by Chiesura (2004) and Zhang et al. (2013). They demonstrated that residents prefer physical and mental health benefits while visiting urban green spaces (i.e., parks). In line with these studies, our results suggest that recreation, aesthetics, and sense of place services are key reasons for residents to visit green space.
Among all the green spaces that exist in our study area, rooftop gardens, green parks, and gardens were perceived as the three most important to provide CES (Fig. 4). A study by Zinia and McShane (2018) found that rooftop gardens were the most used green adaptation strategy because of their economic feasibility and social acceptability. In our results, the rooftop garden attracted the highest importance in terms of providing ecosystem services. This may be because rooftop gardens can be accessed daily by an individual or community. However, most CES studies considered urban parks and gardens as important places to provide CES (Bertram and Rehdanz 2015, Riechers et al. 2018, 2019). An important aspect of CES is that some (e.g., inspiration, sense of place) are related to fishing, fruit picking, and vegetable gathering, and others are related to landscape view (Chan et al. 2012a, Plieninger et al. 2013). Such co-existence sometimes poses a challenge to conserve green spaces that provides multiple categories of CES. Furthermore, CES can also be valued differently by people from different social, demographic, and economic backgrounds (Plieninger et al. 2013, Riechers et al., 2018).
Our study revealed that many of the CES categories are correlated and associated with specific places (Appendix 4). A correlated set of indirectly‐experienced CES categories (natural awareness, religious and spiritual, and cultural heritage) indicates the need for green spaces capable of providing those services specifically. However, in Dhaka city, multiple types of CES are being offered from a single kind of green space. For instance, urban parks are offering both direct (e.g., recreation) and indirect (e.g., aesthetics) kinds of CES. Urban green space offers outdoor meeting places, especially in populous areas. However, the use of urban green space for social interactions, including barbecues, parties, or sports, can impede and negatively affect CES provision for natural observation and recreation (Bertram and Rehdanz 2015). Because of the limited amount of green space, these differences may result in user conflict (Kabisch and Haase 2014). Thus, the utilization and management of CES in this area can become problematic. This problem stresses the need for proper urban green space management for sustainable urban development.
Our study showed the influence of the respondent’s gender, income level, education, and visiting frequency on the perceived importance of CES provided by urban green spaces (Table 2). In contrast to Shi et al.’s (2020) finding for Gaoqu Township in China, we found the effect of gender on specific categories of CES—recreation and education and learning—with women valuing these CES categories more highly than men. This finding is in line with Tyrväinen et al. (2007), Kaczynski et al. (2009), and Schipperijn et al. (2010), who found that women scored higher than men for similar CES‐related activities. A study on Gothenburg on the Swedish west coast by Sang et al. (2016) revealed that, regardless of the type of green spaces, female respondents were more active than men respondents. However, while women in Dhaka city (one of the socially vulnerable groups) generate high demand for green space, their access to those spaces is limited by factors such as insecurity and traffic congestion (Rahman and Zhang 2018). Our results also showed that respondents’ perceptions of CES categories varied by income level. Respondents with higher incomes valued green space for cultural heritage, whereas lower‐income and less educated respondents placed more value on the recreation category. This may be because wealthy respondents are generally more knowledgeable and engaged in art, history, and culture. On the other hand, the lower‐income inhabitants are rarely exposed to historical and cultural information because they remain busy earning money, living hand to mouth. Thus, they value the recreational aspect of green spaces because they can experience these directly.
A dichotomy was revealed in respondents’ ratings by difference in visiting frequency. Respondents who visit green space daily prioritized recreational services and social cohesion. In contrast, respondents who visit those spaces yearly or less prioritized mental satisfaction (Table 2). Bertram and Rehdanz (2015) revealed the influence of visiting frequency on people’s perception of the CES provided by green spaces. They found that respondents who visit green space more than once a month can perceive those places in detail; in contrast, the irregular visitor did not perceive CES accurately. Previous studies showed that park characteristics such as naturalness, spaciousness, sociability, cleanliness, and safety impact residents’ visiting frequency to parks (Harrison et al. 2007, McCormack et al. 2010, Özgüner 2011, Zhang et al. 2013).
Many respondents supported the collective role, mainly of the government, for the management of green spaces and associated CES. In contrast to our findings, Zinia and McShane’s (2018) research found that Dhaka residents preferred to manage rooftop gardens individually. In our study, the rooftop gardens were found to be better managed collectively. Nowadays, Dhaka residents are mostly residing in apartments and sharing their roof with other apartment owners and tenants in the same building. Thus, collective maintenance is crucial. Moreover, supports and encouragement from the government may be needed for the proper management of rooftop gardens.
Our respondents placed high importance on collective efforts for managing CES provided by privately owned green spaces (e.g., rooftop garden) and open and public green (e.g., urban park) spaces. Rahman and Zhang’s (2018) study also demonstrated the need for government and non-government collaboration to take the initiative on green space management to, for example, improve natural settings and increase security. CES may motivate residents to own, use, operate, or protect space for specific purposes, often related to amenities within the space (Chan et al. 2012b). CES affects the actions and activities of landowners in the management of private property (Plieninger et al. 2015). Literature suggests landlords have, over time, become more concerned with CES rather than solely with profit‐maximization (Howley 2013, Hendee and Flint 2014).
Bangladesh has experienced tremendous urban growth since 1973 by converting green spaces into built‐up areas (Hassan 2017). Thus, green space management strategies are urgently needed, and our results suggest a need to develop and manage green spaces that can sustainably provide multifunctional CES. Public management engagement is new for Dhaka, which is a crowded city with few private and public green spaces. Moreover, local people are culturally unfamiliar with the ecological benefits of green spaces. Thus, CES can be the starting point to engage local people in management and decision making. CES is a way to get people to manage green spaces collectively. Because CES is perceived and experienced directly, local people may feel empowered while managing CES with or without organizational (e.g., government, NGO, INGO) involvement. Changes in behavior through awareness‐raising campaigns are also necessary for local people’s proper utilization of green space for CES. Hence, the collaborative approach can be a suitable way to ensure public engagement to transition sustainable management plans to policies.
In Dhaka, urban development strategies have mainly concentrated on densification and infrastructure development. Furthermore, urban management strategies have not involved inhabitants’ participation in the conception, planning, and implementation phases (Ahmed et al. 2019). Inhabitants’ perceptions of CES can inform urban management (Riechers et al. 2018). Large‐scale research on the perceived importance of and preferences for urban green space and its management can help to understand the varied demands of CES that inhabitants from different social backgrounds can have. In our study, the findings on residents’ preferences for CES in Dhaka city will improve urban managers’ knowledge on the benefits of CES and ensure integration of inhabitants’ demands and participation into urban green space management strategies.
For future studies, we suggest reduced item lists of CES because our study found strong correlations between CES categories. A previous study showed a detachment between more nature awareness‐related CES categories (i.e., aesthetics, sense of place) and those focusing on social activities (i.e., social cohesion; Rall et al. 2017). Using the stated preference method through a questionnaire survey on a broader geographical scale to explore local peoples’ perceptions of the importance and management of CES across regions can be one way to reflect citizens’ perspective, preference and demand in management policies.
Although we can quantify the benefits from urban green spaces through various methods and approaches, the ecosystem service framework provides a powerful tool to quantitatively assess the importance and divergence of the ecosystem services among people. Our study adds to the limited available literature on the significance of urban green spaces from the Global South by emphasizing CES’ importance and management from the inhabitants’ perspective.
In Dhaka, the affordability and practicality of managing green spaces are challenged by environmental pollution, poverty, and unplanned, rapid development. For a climate‐exposed city like Dhaka, management of green spaces is not only desirable but also essential for maintaining urban sustainability. CES is a strong entry point to engage the public in managing green spaces. Our study showed the influence of gender, income, educational background, and visiting frequency on CES valuation, with divergent perceptions emerging. Policy and planning related to urban green space management should consider such differences in CES demand from green spaces. Specifically, green spaces should create enough promises for diverse use aiming at recreation and aesthetics. Simultaneously, planners need to plan green spaces with recreational and social activities in areas that can be accessed daily. Prioritization of the rooftop garden among all spaces to provide CES suggests that planners may include favorable policy (e.g., tax exemption) for infrastructures with greenery on the rooftop. However, the high importance of green parks and gardens implies the need for efforts to manage these spaces. Respondents felt that the government could play the most crucial role in managing all these. Furthermore, the collaboration of individuals, community, government, NGO, and INGO was deemed a high priority. Consequently, CES provides the doorway to engage people with organization activities in managing the city to ensure a sustainable future. CES is a comfortable way for residents to relate green space to their lives, motivating them to be stewards of such spaces. A large‐scale questionnaire survey similar to this study can be one tool that planners and policy makers can adapt and apply to assess CES’ importance, and to engage the public in participatory urban management. Though research is emerging, more studies are needed in the Global South to understand people’s perceptions of CES.
