|a Flood exposure is increasing in coastal cities1,2 owing to
growing populations and assets, the changing climate3, and
subsidence4–6. Here we provide a quantification of present and
future flood losses in the 136 largest coastal cities. Using a
new database of urban protection and different assumptions
on adaptation, we account for existing and future flood
defences. Average global flood losses in 2005 are estimated
to be approximately US$6 billion per year, increasing to
US$52 billion by 2050 with projected socio-economic change
alone.With climate change and subsidence, present protection
will need to be upgraded to avoid unacceptable losses of
US$1 trillion or more per year. Even if adaptation investments
maintain constant flood probability, subsidence and sea-level
rise will increase global flood losses to US$60–63 billion per
year in 2050. To maintain present flood risk, adaptation will
need to reduce flood probabilities below present values. In
this case, the magnitude of losses when floods do occur
would increase, often by more than 50%, making it critical
to also prepare for larger disasters than we experience
today. The analysis identifies the cities that seem most
vulnerable to these trends, that is, where the largest increase
in losses can be expected. |
