Hiroshima

Japan

Hiroshima is projected to experience increased heavy rainfall events due to climate change, leading to more frequent flooding. This poses significant threats to the city's infrastructure, property, and public safety. The anticipated increase in precipitation rates could exacerbate soil erosion and negatively affect local ecosystems, as well as compromise water quality and availability. Additionally, urban areas may become more susceptible to intense rainfall, resulting in landslides and transportation disruptions during extreme weather events. These compounded effects require careful attention in city planning and adaptive strategies to mitigate risks. Future projections emphasize the importance of understanding and addressing these climate vulnerabilities to enhance community resilience. However, we have not yet identified technology-enabled climate resilience solutions for Hiroshima, highlighting a significant gap in research and preparedness efforts as the city prepares to confront these escalating climate hazards.

Hazard Outlook
