“…Therefore, a magni cent amount of dense forest vegetation was recorded at DMC. As the NDVI vegetation prominence of a given environment is increased or becomes greater, the enhanced the level of urban green space adaptableness and NDVI value is approaching to + 1 (Wu et al, 2021). Moreover, as Li et al, 2018, for UGS development, the calculated NDVI value should be greater than 0.1, that representing grasslands and shrubs.…”

“…As the elevation of the land increases more, the suitability for UGS development is decreases. In the lower elevation associated with at slope land areas demands less human intervention for design and construction, the more suitable the place for biological habitats to live and the advanced it's the suitability of UGS (Wu et al, 2021).…”

Urban Green Space (UGS) serves as a lung y for city dwellers to breathe. Debre Markos City (DMC) lacks natural recreational areas such as lakes and artificial green spaces. A notable UGS study utilizing multiple contributing factors integrated with the application remote sensing and GIS has a significant advantage in making residents more comfortable. This study, therefore, aimed to assess the existing UGS, quantify it, and identify a suitable area for UGS development. Hence, ten UGS influencing factors were selected. Each criterion was analyzed with the use of its proper algorithm. Multi-criteria decision-making (MCDM) analysis integrated with Analytical Hierarchy Process (AHP) method and RS and GIS were applied. The weighted sum overlay analysis method of spatial analysis was implemented based on the criteria weight of each factor. A 90.6% and 0.8855 accuracy assessment and kappa coefficient were recorded for land use/land cover classification, respectively. The value of consistency ratio was 0.043, which is < 1 and acceptable. Results revealed that 13.12%, 25.47%, 30.89%, 22.49%, and 8.2% of the total area coverage had very high, highly, moderately, poorly and unsuitable for UGS development activity at DMC, respectively. In this study, a resident can access UGS with less than 1km radius distance, closer to the national standard of Ethiopia (i.e. 500m). However, in the existing UGS, a person enforced to walk or travel more than 8.4km distance to get the service. In conclusion, remote sensing and GIS can make life easy to access UGS in the study area with minimum distance and cost, and a short period. It is recommended that policy makers, planners and executive bodies in Ethiopia (highly urbanizing country) should consider future urban demand of the dwellers with proper studies earlier to other urban infrastructures.

“…Consequently, the benefits derived from GI implementation exhibit a high degree of localization [30]. The strategic application of suitability analysis on the installation layout and design of urban GI proves instrumental in discerning optimal GI construction sites and sizes, thereby refining spatial arrangements [31,32]. The utilization of Geographic Information Systems (GIS) enables the identification of priority areas for strategically placing and leveraging GI [30,33].…”

“…This analytical approach assumes paramount importance in enabling urban planners to make informed decisions regarding GI, fostering sustainable urban development [34,35]. However, existing research with limited exploration into the evaluation of GI's suitability [31] is often confined to small-scale analyses and sparse investigations at the broader city or community scales [1].…”

Global climate change has precipitated a surge in urban flooding challenges, prompting the imperative role of green infrastructure (GI) as the linchpin of sponge city construction to enhance urban sustainability and resilience. But the evaluation of urban stormwater resilience faces challenges due to the lack of a comprehensive evaluation framework taking the intrinsic features of the resilience system into account and the insufficient coverage of alternative scenarios’ performance under multiple rainfall return periods. This study, focusing on Fengxi New City, China, evaluates the suitability of GI (i.e., green roofs, rain gardens, and permeable pavements) and constructs a stormwater management model (SWMM) for urban stormwater hydrological simulation. This study also establishes a comprehensive urban stormwater resilience evaluation system and uses quantitative methods to unify the performances of scenarios under different rainfall return periods. Our analytical findings elucidate that the suitability of GI is predominantly concentrated in the northern and western areas of the study area, with the smallest suitable area observed for permeable pavements. Divergent GIs exhibit disparate performances, with rain gardens emerging as particularly efficacious. Importantly, the combination of multiple GIs yields a synergistic enhancement in resilience, underscoring the strategic advantage of adopting a diverse and integrated approach to GI implementation. This study facilitates a deeper understanding of urban stormwater resilience and assists in informed planning decisions for GI and sponge cities.

“…However, with the continuous deepening of the urbanization process [2], the reinforced concrete buildings may bring the agglomeration effect of urban heat waves and form the thermal discomfort region for residents in the coastal urban areas [3][4][5]. The reasonable layout of green land space can usually cope with extreme summer temperatures and avoid the discomfort for local residents or tourists such as heatstroke, thereby improving the ecosystem service function [6,7]. China is still undergoing a rapid urbanization process, shifting from a single urban expansion in the past to a more emphasis on a rational urban planning and layout, along with the harmonious coexistence between people and nature [8,9].…”

The central coast is one of the importantly livable regions in China, and green land plays a meaningful role in improving human settlements through regulating ecosystem services. However, the research on spatiotemporal heterogeneity of green land in different urbanized areas are still lacking in this region, which limits the timeliness of reporting on the land-surface thermal properties of residential environment from green land perspective. To address this issue, the synergistic methodology of “artificial numerical technology -- urban interior mixed pixel classification -- surface radiation energy balance model” was applied to investigate the green land change and its impact on human settlements in Rizhao region, which is known for its coastal ecology and greenery in China and obtained the United Nations habitat award. Main conclusions of this study are below: (1) Although total green land decreased by 474.05 km2, resulting in a decrease of 9.17% in its share of the entire study area from 2000-2022 during the urbanization process, but the greening levels improved within the built-up area, with the greening proportion of 25.34% in 2000 and 42.98 km2 in 2022. (2) Differences in green land at different urbanized regions were first observed, namely, urban greening rate was 37.78% in the old urban areas of 2022, while it was up to 46.43% in new urban areas. More attention was paid to the construction of urban green space during urban expansion, which will inevitably bring better visual and comfort experience to residents. (3) Thermal comfort indicators for urban residents were evaluated in latent heat flux (0-457.83 W/m2), sensible heat flux (0-645.09 W/m2), total available energy (254.07-659.42 W/m2) and others. (4) The lowered cooling temperature effect in the middle, high green land density region was 1.05 ℃ and 2.12 ℃ compared to the low-density region, and the average air temperature was 25.86 ℃. Also, spatial patterns of hot and cold uncomfortable areas were displayed in this study. Overall, this study provides the meaningfully practical reference for exploring the spatiotemporal heterogeneity of green land and its impact on residents' environments from the perspective of land-surface thermal properties in coastal areas of China and around the world.
