Abstract Due to population growth, climate change, and the urban heat island effect, exposure is becoming an important issue faced by built environments. Heat assessment a prerequisite for mitigation measures reduce impact of exposure. However, there limited research on approaches that provides fine-scale spatiotemporal information, integrated with meteorological status human collective as they move about in cities, enable proactive measures. Smart city digital twins (SCDTs) provide new potential avenue addressing this gap, enabling fine scales, human-infrastructure interaction modeling, predictive decision support capabilities. This study aims develop test SCDT forecasting. Meteorological sensors computer vision techniques were implemented Columbus, Georgia, acquire temperature, humidity, passersby count data. These data then into temperature humidity index. A time-series prediction model crowd simulation employed predict future short-term exposures based accumulated efforts. The results demonstrate enhance public safety providing officials tool discovering, predicting, and, ultimately, mitigating community extreme heat.

Hydro-meteorological risk (HMR) management involves a range of methods, such as monitoring uncertain climate, planning and prevention by technical countermeasures, assessment, preparedness for early-warnings, spreading knowledge awareness, response recovery. To execute HMR many models tools, ranging from conceptual to sophisticated/numerical methods are currently in use. However, there is still gap systematically classifying documenting them the field disaster management. This paper discusses various used assessment its via potential nature-based solutions (NBS), which actually lessons learnt nature. We focused on three hydro-meteorological hazards (HMHs), floods, droughts heatwaves, their relevant NBS. Different methodologies related chosen HMHs considered with respect exposure, vulnerability adaptation interaction elements at risk. Two widely flood fuzzy logic (e.g. analytic hierarchy process) probabilistic methodology univariate multivariate probability distributions). kinds indices have been described literature define drought risk, depending upon type purpose evaluation.

Exposure to heat has a range of potential negative impacts on human health; hot weather may exacerbate cardiovascular and respiratory illness or lead stroke death. Urban populations are at increased risk due the Heat Island (UHI) effect (higher urban temperatures compared with rural ones). This led extensive investigation summertime UHI its effects, whereas far less research focuses wintertime UHI. low temperature also leads illnesses, in fact, UK, annual cold-related mortality outweighs heat-related mortality.

With rapid urbanization, population growth and anthropogenic activities, an increasing number of major cities across the globe are facing severe urban heat islands (UHI). UHI can cause complex impacts on environment human health, it may bring more effects under heatwave (HW) conditions. In this paper, a holistic review is conducted to articulate findings synergies between HW corresponding mitigation measures proposed by research community. It worth pointing out that most studies show areas vulnerable than rural during HWs, but opposite also observed in some studies. Changes energy budget drivers discussed compared explain such discrepancies. Recent indicate albedo, vegetation fraction irrigation lower temperature HWs. Research gaps topic necessitate concerning developing countries. Moreover, multidisciplinary considering factors as UHI, HW, comfort, pollution dispersion efficacy should be provide accurate explicit guidance planners policymakers.
