Lyon
France
Lyon is projected to face moderate climate risks in the future. This city will experience an increase in heatwaves, posing health risks for vulnerable populations. Additionally, flooding risks are anticipated due to intensified heavy rainfall events driven by climate change. Increasing urban temperatures may exacerbate these challenges, contributing to urban heat island effects. Furthermore, drought conditions could become more prevalent, impacting water supply and agricultural practices. These interlinked challenges highlight significant vulnerabilities that will necessitate urgent adaptive measures. Although technology-enabled climate resilience solutions for Lyon have not yet been documented, the city’s projected climate threats underscore the critical need for climate adaptation strategies to effectively reduce potential impacts and enhance community resilience moving forward.
