Guidelines, tools and showcases

Stress test as part of national policy in climate adaptation

Tiered approach

Three steps:

1: Vulnerability scan

Climate resilient cities

Urban areas (re)developed in such a way,

that they are better able to cope with hazards from

more extreme weather.

Hazard assessment:

- Flooding

- Drought

- Heat stress

- Land subsidence

(and contribute to a better urban environment)
