With accelerating surface warming trends in urban regions, cities like Algiers are increasingly exposed to extreme heat, contributing a growing concern over heat-related illnesses. For comprehensive long-term assessment (2001–2023) of risks Algiers, multi-decade satellite, meteorological, and census data were used this study map assess spatial patterns the Heat Health Risk Index (HHRI) within framework established by Intergovernmental Panel on Climate Change (IPCC) incorporating hazard, exposure vulnerability components. The Universal Thermal (UTCI) was then calculated thermal stress levels during same period. Following this, addressed critical research gap coupling HHRI UTCI identified hotspots using Getis-Ord Gi* statistical analysis tool. Our findings reveal that intensity has increased time since “very-low” risk areas had an outstanding decrease (93%) 6 °C rise 23 years reaching “very strong heat stress” level. coupled index demonstrated greater different compared alone, suggesting both indicators enhances sensitivity assessment. Finally, persistently central eastern regions call for localized, targeted interventions those highlight value remote sensing informing policymakers enhancing climate resilience.

Cities are facing increased heat-related health risks (HHRs) due to the combined effects of global warming and rapid urbanization. However, few studies have focused on HHR assessment based fine-scale information. Moreover, most only analyze spatial patterns do not explore potential driving factors. In this study, we estimated HHRs “hazard–exposure–vulnerability” framework by using multisource data, including modified thermal–humidity index (MTHI), population density, land cover. Then, variations in among different local climate zones (LCZs) at fine scale were analyzed detail. Finally, compared contributions LCZs types cover their three components multiple linear regression models. The results indicate that pattern was from those individual components, high-hazard regions mean high HHRs. There huge LCZs. built-up typically had much higher than natural ones, with compact severe risk. LCZ 6 (open low-rise buildings) a relatively low should be paid more attention future urban planning. Compared LCZs, covers better explained HHR. contrast, predicted surface temperatures. both made slight heat exposure vulnerability. Furthermore, manmade buildings impervious areas contributed covers. Therefore, arrangement is worthy further investigation perspective mitigation.

Spatially Explicit Assessments of Heat-Related Health Risks: A Literature Review

Remote Sensing, Год журнала: 2024, Номер 16(23), С. 4500 - 4500

Опубликована: Ноя. 30, 2024

Extreme heat events, or heatwaves, exert significant impacts on human society, ecosystems, and the economy. The continuous development of remote sensing technology has facilitated acquisition high-quality data for assessing health risks associated with these extreme events. This study systematically reviews evaluation factors assessment framework a spatially explicit heat-related risks. contribution geospatial big data, particular focus satellite observations, to assessments was investigated. Moderate Resolution Imaging Spectroradiometer (MODIS) Landsat surface temperature (LST) are identified as two most widely utilized sources mapping hazards. incorporation multi-sensor along implementation spatiotemporal fusion downscaling techniques, enhances both spatial resolution temporal frequency hazard characterization. It is essential consider issues justice equality in heat-resilient planning mitigation practices. Integrating heatwave risk results analyses urban morphology, land use functions infrastructure can provide critical information government agencies strategically plan layout, functions, public service facilities while optimizing enhancing green infrastructures.
