Neighborhood Green Spaces and Social Capital: The Mediating Role of Affordances and Motivations to Use
Green spaces have the potential to foster social capital, yet we do not fully understand what motivates people to use these spaces and how green space use leads to social benefits. Recent studies suggest that perceptions of green space are more important than just physical attributes in encouraging usage and fostering social connections. Perceptions can determine green space usage, but we do not yet know exactly how perceptions of green space rel…
The influence of urban morphological changes on pluvial flooding during urban expansion
Examined how urban form changes influence pluvial flooding using urban expansion data • Revealed key urban form indicators and their interplay associated with changing flood volume • Observed a threshold effect with increasing pre-expansion urban coverage • Compact green spaces with limited total imperviousness can mitigate flood risk • Provides actionable insights for planning flood-resilient urban growth Urban expansion alters landscape structu…
Toward healthy neighborhood thermal environments: Interpretation of thermal comfort and rapid identification of hotspot areas using image-based metrics and explainable machine learning
Residential tree canopy configuration and mortality in 6 million Swiss adults: A longitudinal study
National Research Foundation, Prime Minister's Office, Singapore under its Campus for Research Excellence and Technological Enterprise programme and ETH Zurich
Beyond just green: Explaining and predicting restorative potential of urban landscapes using panorama-based metrics
More than a canopy cover metric: Influence of canopy quality, water-use strategies and site climate on urban forest cooling potential
Urban tree canopy cover is a promising solution for mitigating heat island. • Data-driven guidance on tree selection and planting locations is still limited. • Four research priorities are proposed, requiring a collaborative research effort. • Cross-climate morphological and physiological characteristics are desired. • Integration with atmospheric boundary layer models is suggested
Use and non-use of parks are dictated by nature orientation, perceived accessibility and social norm which manifest in a continuum
Given the importance of urban parks for the well-being of urban dwellers, coupled with inequitable access to parks that seems widely reported in many cities, understanding the underlying factors that determine use and non-use of parks is a necessary step towards encouraging greater park usage. Past studies have highlighted the role of several influential factors, but rarely were these examined comprehensively in a single study to understand their…
The role of urban nature experiences in sustainable consumption: A transboundary urban ecosystem service
Assessment of visual landscape quality of urban green spaces using image-based metrics derived from perceived sensory dimensions
Development and application of 3D spatial metrics using point clouds for landscape visual quality assessment
Assessment of mediators in the associations between urban green spaces and self-reported health
Although urban green spaces (UGS) are widely known to confer health benefits, evidence of the specific mechanisms that mediate the pathways from UGS provision and exposure to health outcomes remains limited. In particular, the question of whether exposure to UGS is an independent variable or a mediator in UGS-health linkages remains inadequately addressed. Using a nationally representative household survey in Singapore, this study investigated tw…
The influence of the Covid ‐19 pandemic on the demand for different shades of green
COVID‐19 has heightened the dependence of urban dwellers on cultural ecosystem services provided by urban green spaces (UGS), specifically in regard to the provision of recreational opportunities, and psychological and physical health benefits arising from their use. As different types and levels of cultural ecosystem services are provided by different types of UGS, people may seek out different UGS to satisfy personal needs over various phases o…
Relative importance of quantitative and qualitative aspects of urban green spaces in promoting health
The health benefits of urban green spaces (UGS) are important considerations in the design of urban environments. Researchers have analysed how the quantity of UGS impacts health outcomes, but less work has quantified the relative health benefits of different components of UGS provision. We examined the associations of different indicators of UGS provision with self-reported mental and general health based on a national representative household s…
A conceptual framework to untangle the concept of urban ecosystem services
Urban ecosystem service (UES) is becoming an influential concept to guide the planning, design, and management of urban landscapes towards urban sustainability. However, its use is hindered by definitional ambiguity, and the conceptual bases underpinning its application remain weak. This is exemplified by two different but equally valid interpretations of UES: “urban ecosystem services”, referring to ecosystem services from analogs of natural and…
Height–diameter allometry for the management of city trees in the tropics
Trees are important components of urban greenery because of their large stature and longevity, and their ability to enhance the environmental quality of city landscapes. However, benefits and hazards associated with trees depend on their size, which changes over time and varies among species. While urban trees are often measured during routine management, the full value of these data is rarely realised. Our study uses nation-wide inspection recor…
Does geo-located social media reflect the visit frequency of urban parks? A city-wide analysis using the count and content of photographs
Given the importance of parks and green spaces for outdoor recreation in cities, numerous studies have attempted to describe patterns of usage and understand their determining factors. Recently, social media has emerged as a potentially valuable tool to examine people's use of parks. This study examines park use in Singapore based on the count and visual content of photographs geo-located within parks. Measures of park use-the number of photo-use…
Multi-year comparison of the effects of spatial pattern of urban green spaces on urban land surface temperature
Associations between Urban Green Spaces and Health are Dependent on the Analytical Scale and How Urban Green Spaces are Measured
Although the benefits from exposure to urban green spaces (UGS) are increasingly reported, there are important knowledge gaps in the nature of UGS-health relationships. One such unknown area is the dependence of UGS-health associations on the types of UGS studied, the way they are quantified, and the spatial scale used in the analysis. These knowledge gaps have important ramifications on our ability to develop generalizations to promote implement…
Window View and the Brain: Effects of Floor Level and Green Cover on the Alpha and Beta Rhythms in a Passive Exposure EEG Experiment
With the growing interest among researchers, practitioners, and urban decision makers in the influence of the built environment on peoples' health, there is increasing emphasis on using scientific knowledge to inform urban design, including methods of neuroscience. As window views are the most immediate medium of visual connection with one's neighbourhood, we surmised that the quality of this view would have an impact on the mental health and wel…
