Next-Generation Cities: Protecting People from Climate Change and Health Risks

Executive Summary

Health impacts caused by climate change represent "the biggest threat to global public health in the 21st century”. Cities, which face direct and intense challenges from heatwaves, air pollution, extreme weather, and natural disasters, are expected to play a vital frontline role in safeguarding planetary and human health. According to World Bank estimates, by 2050, LMICs are expected to experience approximately 15 million additional deaths due to heat stress, infectious diseases, and nutritional disorders, alongside an economic loss of approximately $15 trillion. Unplanned urban development can exacerbate health and environmental risks, making strategic urban planning essential.
