Climate risk assessment in urban environments

Abstract

The majority of climate change vulnerability and health concerns are concentrated in informal settlements. Hazardous locations can be found in many communities, including low-lying ground along exposed riverbanks and ocean coasts, degraded slopes, and buildings that don't adhere to building rules. A complex network of interrelated social, ecological, and technical processes makes up the urban environment. Global warming is expected to have a wide range of repercussions on ecosystems and society, which naturally increases complexity, in addition to other environmental, economic, and political concerns.By integrating satellite, environmental, and socioeconomic data using an integrated method that included remote sensing, statistical modeling (PCA), and geographical analysis, this work created a spatially explicit diagnosis of urban climate risks in Rabat. Three primary risk factors were investigated: air pollution (PM2.5 and NO 2 ), urban heat (heat island), and related socioeconomic vulnerability.
