Defensive approaches to extreme weather

The problem:
Extreme weather such as floods, droughts and heatwaves has huge human and economic costs at present. The problem is set to get worse not only due to climate change but also because of projected demographic changes such as a growing and aging global population, increasingly located in areas exposed to extreme weather.

Key facts/ messages:
– Combining scenarios of demographic change with predicted climate change demonstrates that people and their assets will be increasingly exposed to extreme weather over coming decades.
– There are a range of defensive options that can reduce the impact of extreme weather on people.
– While engineering options such as sea walls tend to be the most effective, ecosystem-based options can be more affordable and have positive additional benefits. Hybrid options can combine the advantages of both.
