A Framework for Urban Parks: Using Social Media Data to Assess Bryant Park, New York
Landscape Journal, 2022
Parks play a critical role in the health and well-being of people in urban environments. Recent events such as the COVID-19 pandemic have underscored the importance of public parks, particularly in cities. To maximize the benefits of these spaces, it is important to understand the social dimension of site user experiences within successful urban parks. Social media data provide a means to assess public places through the lens of large quantities of site users over time. Recent landscape research studies provide assessments of urban and nature-based locations using social media data and are predominantly quantitative in their methodologies (Havinga et al., 2021; Donahue et al., 2018; Wood et al., 2013). However, incorporating mixed methods into existing approaches can create a better understanding of site user experiences. This study uses 11,419 Tripadvisor reviews from the years 2010 to 2018 in a multi-step process, where qualitative content analysis builds upon Latent Dirichlet allocation (LDA) modeling topics to assess the semantic content of Bryant Park, NY. The new framework emerging from this process separates site user perceptions and sentiment positivity into categories. Site design elements are revealed as a major positive focus of site users, along with the position of the park within the urban fabric, site activity consisting of passive pastimes, and the essence of the space related to emotions. The study's findings can provide guidance for designers and park managers for the creation of successful urban parks and provide another baseline for research on New York City's parks.
Geolocated social media as a rapid indicator of park visitation and equitable park access
Computers, Environment and Urban Systems, 2018
Understanding why some parks are used more regularly or intensely than others can inform ways in which urban parkland is developed and managed to meet the needs of a rapidly expanding urban population. Although geolocated social media (GSM) indicators have been used to examine park visitation rates, studies applying this approach are generally limited to flagship parks, national parks, or a small subset of urban parks. Here, we use geolocated Flickr and Twitter data to explore variation in use across New York City's 2143 diverse parks and model visitation based on spatially-explicit park characteristics and facilities, neighborhood-level accessibility features and neighborhood-level demographics. Findings indicate that social media activity in parks is positively correlated with proximity to public transportation and bike routes, as well as particular park characteristics such as water bodies, athletic facilities, and impervious surfaces, but negatively associated with green space and increased proportion of minority ethnicity and minority race in neighborhoods in which parks are located. Contrary to previous studies which describe park visitation as a form of nature-based recreation, our findings indicate that the kinds of green spaces present in many parks may not motivate visitation. From a social equity perspective, our findings may imply that parks in high-minority neighborhoods are not as accessible, do not accommodate as many visitors, and/or are of lower quality than those in low-minority neighborhoods. These implications are consistent with previous studies showing that minority populations disproportionately experience barriers to park access. In applying GSM data to questions of park access, we demonstrate a rapid, big data approach for providing information crucial for park management in a way that is less resource-intensive than field surveys.

Subjective values of urban green spaces are difficult to quantify and thus easily overlooked in planning processes. Accounting for such values is an important challenge in developing sustainable cities. Crowdsourcing methods, such as big data and smart phone applications, have emerged as promising methods to improve insights into subjective perceptions and preferences. However, we know little about how well these relatively new methods actually quantify subjective values. We assessed several of these new methods by comparing observations of use (n = 1009) to three crowdsourcing methods in one large park in Amsterdam, the Netherlands: a dedicated mobile app providing in situ stated preferences (n = 377), passive social media (n = 78) and a municipal reporting app (n = 187). We show that observed use and passive social media only captured user quantity and were not able to identify green space qualities that are important for mental health functions, such as how relaxing or safe a location is. The dedicated mobile app combined with observed use helped to identify priority locations for improvement. Our findings emphasize that if inadequate measures are used in smart city developments, subjective values and specific user groups will continue to be overlooked in planning processes.
User-generated content (UGC) is a relatively young field of research; however, it has been proven useful in disciplines such as hospitality and tourism, to elicit public opinions of place usage. In landscape architecture and urban planning, UGC has been used to understand people's emotions and movement in a space, while other areas and additional functions are yet to be discovered. This paper explores the capability of UGC in revealing city-scale park management problems and the applicability of social media as a future tool in bridging visitor feedback to city parks and recreation department staff. This research analyzed the spatial characteristics and patterns of Google Maps review quantity, rating score, and review comments. The results of this pilot study indicate the spatial and structural features of the Chicago parks and demonstrate distribution problems, financial investment priority concerns, park usage characteristics, and user preferences of the park attributes. Findings affirm that user-generated online reviews can be used as an alternative and self-reporting data source to effectively assess the natural performance and users' experience of city parks and can potentially serve as an evaluative tool for public park management.

Users' preferences and values in urban parks is important information for establishing social marketing strategies and therefore policymakers to consider. This study investigates the issue by analyzing social media data. User-generated data were collected from Instagram and content analysis was employed to identify physical features and values people assigned to urban parks from text descriptions of Instagram posts. Findings revealed that natural features are more frequently mentioned than non-natural elements. Aesthetic quality, happy feeling, and restorative experience are the most frequently mentioned value expressions among the six categories of identified values. Significant association rules are established between physical features and values. Natural elements such as lawns, water features, wildlife and plants are more likely to be associated with happiness and restorative experience than aesthetic value. Artificial elements, flowers, and public art stimulate aesthetic quality. Implications for planning urban green environments are discussed. Social media platforms offer a novel entry point to uncover and monitor public interests and perceptions of specific venues such as recreational settings. Social media data provide actionable insights for promotional campaigns and inform decision-making pertaining to individuals and collective well-being.
Tweeting the High Line Life: A Social Media Lens on Urban Green Spaces
Sustainability, 2020
The objective of this study is to investigate elevated parks as urban green spaces using social media data analytics. Two popular elevated parks, the High Line Park in New York and the 606 in Chicago, were selected as the study sites. Tweets mentioning the two parks were collected from 2015 to 2019. By using text mining, social media users’ sentiments and conveyed perceptions about the elevated parks were studied. In addition, users’ activities and their satisfaction were analyzed. For the 606, users mainly enjoyed the free events at the park and worried about possible increases in housing prices and taxes because of the 606. They tended to participate in physical activities such as biking and walking. Although the 606 provides scenic observation points, users did not seem to enjoy these. Regarding the High Line, users frequently mentioned New York City, which is an important aspect of the identity of the park. The High Line users also frequently mentioned arts and relaxation. Overa...

With the prevalence of smartphones, new ways of engaging citizens and stakeholders in urban planning and governance are emerging. The technologies in smartphones allow citizens to act as sensors of their environment, producing and sharing rich spatial data useful for new types of collaborative governance set-ups. Data derived from Volunteered Geographic Information (VGI) can support accessible, transparent, democratic, inclusive, and locally-based governance situations of interest to planners, citizens, politicians, and scientists. However, there are still uncertainties about how to actually conduct this in practice. This study explores how social media VGI can be used to document spatial tendencies regarding citizens’ uses and perceptions of urban nature with relevance for urban green space governance. Via the hashtag <em>#sharingcph</em>, created by the City of Copenhagen in 2014, VGI data consisting of geo-referenced images were collected from Instagram, categorised a...

The concept of cultural ecosystem services has been increasingly influential in both environmental research and policy decision making, such as for urban green spaces. However, its popular definitions tend to conflate “services” with “benefits”, making it challenging for planners to employ them directly to manage urban green spaces. Thus, attempts have been made to redefine cultural ecosystem services as the function of cultural activities in environmental spaces which result in people’s enjoyment of cultural ecosystem benefits. The operability of such a redefinition needs to be evaluated, which this study seeks to achieve with Bishan-Ang Mo Kio Park in Singapore presenting itself as a prime case study research area. Transdisciplinary mixed methods of a public participation geographic information system, which leverages on spatial data from public park users, and social media text mining analysis via Google reviews were used. A wealth of cultural ecosystem services and benefits were...
Ecosystem Services, 2022
Sustainable urban and metropolitan planning is increasingly benefiting from differentiated assessments of ecosystem services. Cultural ecosystem services (CES) are particularly relevant for urban residents' mental and physical health, yet, quantification and mapping of CES are often challenging, especially so in the Global South. The use of social media data (SMD), which has recently gained importance for assessing CES at larger spatial and temporal scales, provides a promising entry point for mitigating this informational gap in land-use planning. However, its application is mainly limited to European and North American cases and rarely applied to datascarce urban regions in the Global South, with South America as no exception. Addressing this geographical gap, this study assesses CES of urban green spaces in the city of Cali, Colombia, based on 1,686 crowdsourced and geolocated photographs, and compares those results with a metropolitan scale CES potential assessment based on expert opinions performed in a previous study. Despite some important limitations primarily related to Flickr as a data source, we demonstrate the utility of this approach, especially for understanding the fine-scale generation of CES by small green spaces located within the urban fabric that are overlooked in the metropolitan scale expertbased assessment. These green spaces are highly relevant as inner-city pockets for CES production, especially in the form of "existence value" and "aesthetic experiences", in contrast to green areas highlighted by experts at the metropolitan scale that serve primarily recreational purposes. Our results indicate the large potential of SMDbased CES assessment approaches for informing urban planning processes in the Global South.
