Lisbon

Portugal

Lisbon is projected to face increasing frequent heatwaves as climate change progresses, which poses significant risks to public health and infrastructure. In response, the city implements a range of technology-enabled climate resilience solutions that prioritize planning and monitoring. These include advanced climate analytics, robust hazard forecasting, and comprehensive weather monitoring systems specifically designed to address climate challenges. Furthermore, Lisbon has developed effective stormwater drainage systems to manage water resources, minimizing flooding risks during extreme weather events. These current and proposed initiatives reflect Lisbon's commitment to enhancing its adaptive capacity, ensuring a resilient urban environment amid the growing impacts of climate change.
