Green spaces provide substantial but unequal urban cooling globally

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Sept. 2, 2024

Climate warming disproportionately impacts countries in the Global South by increasing extreme heat exposure. However, geographic disparities adaptation capacity are unclear. Here, we assess global inequality green spaces, which urban residents critically rely on to mitigate outdoor stress. We use remote sensing data quantify daytime cooling greenery warm seasons across ~500 largest cities globally. show a striking contrast, with having ~70% of North (2.5 ± 1.0 °C vs. 3.6 1.7 °C). A similar gap occurs for benefits received an average resident these (2.2 0.9 3.4 This is due discrepancies space quantity and quality between South, shaped socioeconomic natural factors. Our analyses further suggest vast potential enhancing while reducing inequality.

Shared insights for heat health risk adaptation in metropolitan areas of developing countries

iScience, Journal Year: 2024, Volume and Issue: 27(5), P. 109728 - 109728

Published: April 12, 2024

Global warming has led to a surge in heat health risks (HHRs), the impacts of which are particularly pronounced metropolitan areas developing countries. In current study, six - Beijing, China; Cairo, Egypt; Jakarta, Indonesia; Mumbai, India; Rio de Janeiro, Brazil; and Tehran, Iran were selected as study area further differentiate built-up landscapes by utilizing concept local climate zones. Moreover, we assessed similarities differences HHR associated with landscape. Results revealed 30.67% higher compact than open type. Urban green spaces played an effective but differentiated role mitigating HHR. That is, low vegetation urbanized trees suburban significantly mitigated Collectively, our findings emphasize planning management addressing provide empirical support for implementing mitigation adaptation strategies.

Assessing heat vulnerability in Philadelphia using geographically weighted principal component analysis (GWPCA): A geospatial big data-driven approach

International Journal of Applied Earth Observation and Geoinformation, Journal Year: 2024, Volume and Issue: 127, P. 103653 - 103653

Published: Jan. 16, 2024

The impact of climate change, specifically more intense heat waves, has increased concerns about vulnerability, particularly among high-risk populations. This research utilizes multi-source geospatial big data and employs Geographically Weighted Principal Component Analysis (GWPCA) as well Global (GPCA) to analyze vulnerability in Philadelphia. Using GPCA, four key components are identified Sensitivity, Adaptive Capacity, proxy for Exposure, respectively. subsequent GWPCA analysis reveals localized differences, showing distinct patterns across the city. Notably, Sensitivity factors prominent western southwestern regions, whereas Exposure is dominant central southern parts. study underscores significance considering spatial heterogeneity when assessing vulnerability. It also highlights potential capture subtle disparities within specific areas proposes targeted strategies reduce affected communities. Therefore, incorporation an advanced model enables a comprehensive understanding complex urban environments. progress crucial enhancing resilience adaptation evolving conditions.

Ecosystem service mismatches evidence inequalities in urban heat vulnerability

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 922, P. 171215 - 171215

Published: Feb. 28, 2024

Exposure to heat poses a pressing challenge in cities, with uneven health and environmental impacts across the urban fabric. To assess disparities vulnerability its justice implications, we model supply-demand mismatches for ecosystem service (ES) temperature regulation. We integrated remote sensing, health, socio-demographic data Artificial Intelligence Environment Sustainability (ARIES) geographical information system tools. computed composite indicators at census tract level cooling supply, as measure of demand. do so context mid-size city Vitoria-Gasteiz, Basque Country (Europe). mapped relative after identifying analysed their relationship factors. Our findings show vulnerability, increased exposure observed among socio-economically disadvantaged communities, elderly, people issues. Areas associated higher income levels lower ES mismatches, indicating regulation supply reduced vulnerability. The results point need nature-based mitigation interventions that especially focus on more communities.
