Hurricane Katrina, which hit the American city of New Orleans 10 years ago this month, has raised the bar for disaster risk management, according to the UN Office for Disaster Risk Reduction (UNISDR).
The category 5 hurricane is considered the worst in the history of the United States.
It inundated 80 per cent of New Orleans, and claimed the lives of nearly 2000 people.
Stephanie Coutrix spoke with UNISDR Spokesperson Denis McClean.
She began by asking him what the global community has learnt during the past decade from Hurricane Katrina.
