Mitigating urban heat island through neighboring rural land cover

Nature Cities, Journal Year: 2024, Volume and Issue: 1(8), P. 522 - 532

Published: July 5, 2024

Abstract Globally, the deteriorating Urban Heat Island (UHI) effect poses a significant threat to human health and undermines ecosystem stability. UHI mitigation strategies have been investigated utilized extensively within cities by provision of green, blue or gray infrastructures. However, urban land is precious limited for these interventions, making it challenging address this issue. Neighboring rural cover may serve as cooling source great potential mitigate through processes such heat absorption circulation. This study aims following questions: (1) what location neighboring effectively entire city (2) are key parameters landscape. We quantitative qualitative relationships between UHI, drawing on geographical environmental data from 30 Chinese 2000 2020. found that extending outward boundary, approximately half equivalent diameter city, had most pronounced impact mitigation. The number adjacency landscape patches (a patch homogeneous nonlinear basic unit pattern, distinct its surroundings) emerged two factors in mitigating with their individual reduce up 0.5 °C. proposed recommendations were avoid fragmentation enhance shape complexity distribution uniformity patches. work opens new avenues addressing high-temperature catastrophes perspective, which also promote coordinated development areas.

Understanding urban heat vulnerability: Scientometric analysis of five decades of research

Urban Climate, Journal Year: 2024, Volume and Issue: 56, P. 102035 - 102035

Published: June 27, 2024

Urban Heat Vulnerability (UHV) has received increasing attention over the last two decades due to exacerbation of global warming and Island (UHI) effect, amid rapid urbanisation climate change. While there been a notable growth in UHV research, systematic reviews meta-analyses focusing on broader range issues research trajectories are notably absent. This study aims provide comprehensive understanding historical progression, current clusters, emerging trends by utilising scientometric method. It examines 2340 UHV-related scholarly articles published past fifty years (1970s 2020s). The major findings this analysis are: (a) is an area expected rapidly expand; (b) clustered around five interconnected key areas: planning architectural design; environment ecology; public health wellbeing; meteorology; remote sensing; (c) recent shift focus towards wellbeing perspectives studies highlights importance human-social interdisciplinary collaboration; (d) Remote sensing, particularly supported machine learning, significant technical tool research; (e) aligns with UN sustainable development goals contributes achieving urban sustainability resilience. Further advancements will require collaboration, technological innovations, targeted policies effectively address heat impacts protect vulnerable populations.

Urban heat island patterns in garden cities: Putrajaya as a case study

Indoor and Built Environment, Journal Year: 2024, Volume and Issue: 33(8), P. 1431 - 1446

Published: April 3, 2024

The garden-city model, characterised by sprawling urban expansion and extensive open spaces, features green water surfaces alongside substantial road networks, large parking lots unshaded lands. This diverse landscape contributes to uneven air temperature distribution within the city. Our study investigated heat island (UHI) patterns in various environments Putrajaya, focusing on rural, business, residential near-water areas. Atmospheric data were collected over a year. Putrajaya exhibits two distinct UHI patterns: cool-day-hot-night zones hot-noon-temperate-elsewhere impermeable Business areas display alternating based seasonal climatic conditions anthropogenic factors. efficacy of artificial bodies as countermeasure garden cities depends size body nature surrounding land cover. Shaded exhibit intensities limited 3°C, while areas, regardless proximity surfaces, experience up 6°C. Overall, model tends restrict variations −1 3°C compared −2 4°C nearby Kuala Lumpur.
