Danger for developing countries

Developing-country cities move up the list when flood costs are measured as a percentage of city gross domestic product (GDP). Many of them are growing rapidly, have large populations, are poor, and are exposed to tropical storms and sinking land.

The study, (World Bank / OECD) forecasts that average global flood losses will multiply from $6 billion per year in 2005 to $52 billion a year by 2050 with just social-economic factors, such as increasing population and property value, taken into account.

Coastal cities could cost $1 trillion a year

Add in the risks from sea-level rise and sinking land, and global flood damage for large coastal cities could cost $1 trillion a year if cities don’t take steps to adapt.

Be prepared!

Protection and preparation are especially important. A devastating flood in a key city can stall the entire economy. Preparation will save lives and money in the future.
