“…As shown in Figure 1, canopy cover is a subset of vegetation cover, parks overlap with both vegetation cover and canopy cover. The island-wide vegetation cover and canopy cover was obtained from an earlier study [54]. These spatial data were derived from WorldView-2 satellite images with 2-m resolution for Singapore acquired in 2015.…”

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 implementation and facilitate comparative studies across different socio-cultural and socio-economic contexts. We conducted a study in Singapore to examine the dependence of UGS-health associations on the metrics for quantifying UGS (vegetation cover, canopy cover and park area) in different types of buffer area (circular, nested and network) at different spatial scales. A population-based household survey (n = 1000) was used to collect information on self-reported health and perception and usage pattern of UGS. The results showed that although all three UGS metrics were positively related to mental health at certain scales, overall, canopy cover showed the strongest associations with mental health at most scales. There also appears to be minimum and maximum threshold levels of spatial scale at which UGS and health have significant associations, with the strongest associations consistently shown between 400 m to 1600 m in different buffer types. We discuss the significance of these results for UGS-health studies and applications in UGS planning for improved health of urban dwellers.

“…The assessment of the biodiversity values of secondary forests followed the map of cohesive habitat networks for biodiversity done by Hamid and Tan [5] in 2017, by overlapping the boundary of the secondary forest in 2021 with the map of Singapore's cohesive habitat networks.…”

“…To predict the future land use of secondary forests in Singapore, the 2019 Master Plan map of Singapore is required, and it was downloaded from the URA official website. To assess the biodiversity value in terms of an ecological network, a map of cohesive habitat networks was collected from the research paper of Hamid and Tan [5].…”

“…According to current data from United Nations World Population Prospects, Singapore's population density is among the world's highest-with roughly 8749 people per square kilometer of land in 2022. Singapore is a high-density city, in which biodiversity conservation is threatened by future competing land use developments [5]. According to the Urban Redevelopment Authority (URA) 2019 Master Plan of Singapore, it is foreseen that a mass of secondary forests will be developed in the coming decade.…”

With past and continued loss of secondary forests in urban areas, this paper aims to assess the current distribution of secondary forests and evaluate the ecological values of secondary forests in terms of patch sizes, plant density and biodiversity values by using the analysis tools of GIS and FRAGSTATS. According to the analysis in this paper, over 1782 ha of secondary forest cover in Singapore has been lost due to the urbanization, such as residential and infrastructure development, in the past decade. It is estimated that about 7331 ha of secondary forests are planned to be cleared for new development. The future loss of secondary forests is about 1.2 times larger than the entire area of all parks and nature reserves in Singapore. It is shown that secondary forests became more fragmented compared with 2011, and more than 80% of patches are smaller than 1 ha. Most of the secondary forests’ patches are with high plant density and high biodiversity values in terms of ecological connection. Discussions towards the improvement of biodiversity and phase development planning for secondary forests in a tropical high-density city are addressed in this paper. There is lots of potential to integrate secondary forests into future land use developments for improving biodiversity based on the literature review and analysis results.

“…The ecological network is based on the concept of network, space, and landscape integration. The uses of landscape ecology and remote sensing technology for biodiversity conservation and analysis are essential to explain how tools can be developed for environmental networks and their functions in biodiversity management (Hamid & Tan, 2017). In Chittagong city, it contradicts the regional plan to reduce green coverage from 46.20 to 32.56%.…”

The urban green belts mechanism was part of the city planning landscape of the 20th century for sustainable urban management. Greenbelt is a land-use policy and designation used in land use/land cover planning. The green belt has long been a design policy that also has a base in London accepted by other renowned cities such as Ottawa, Birmingham, Seoul, Frankfurt, Tehran's, Mashhad, Beijing, Gulbarga, Ontario, etc. Benefits include the value of living close to the green belts, recreational resources, productive farmland, transport connectivity, and a wide range of life support ecosystem services. The study investigated the present green space condition and its infrastructure with other cities around the world and prescribed the other mechanism in reviewing the Master Plan and the Detailed Area Plan of Chittagong city, Bangladesh along with a significant number of journal articles, books, and reports. The study found that the city of Chittagong is facing various problems in the present decades with its various problems like green space, recreational facilities, disaster, public health risk and so many. It also found that the city's geographical condition is suitable for developing an effective green belt in its periphery area. Although green wedges is another park system proposal for the barriers of urban green belt. The importance of land allocation for urban green space is usually neglected or easily reported in the city transition region. Besides, the city of Glasgow, Stockholm, Melbourne, and Copenhagen, etc. are accepted green wedges mechanisms. For some barriers as like as industrial development and some exclusive economic zone, some green wedges are much suitable in the gap of urban green belt in Chittagong city. The concept of green belt and green wedges both supports sustainable urban management in the city of Chittagong. However, these findings and analysis will be of great importance to the urban planners and decision-makers, for making environment-friendly sustainable future planning of modern and the planned Chittagong city.
