Extreme heat case studies

This page presents case studies of extreme heat events and responses from different regions and contexts.

The examples illustrate how heat risks have been experienced, managed, and addressed around the world. They highlight impacts and showcase valuable lessons learned. Together, they provide practical insights to inform preparedness, planning, and risk reduction efforts for future heat events.

In 2022 alone, Portugal lost over 2,000 lives to extreme heat. In response, Amadora, a UNDRR Making Cities Resilient Resilience Hub, has taken bold steps to protect its people.
