It also says these financial losses are concentrated in fast-growing, middle-income countries because such countries’ high-value assets are becoming more exposed. The average impact of disasters in such nations equaled 1 percent of gross domestic product between 2001 and 2006 — 20 times higher than the average for high-income countries.
The World Bank says climate-resilient development is the answer — but warns it isn’t cheap, with upfront costs running as much as 50 percent higher than traditional development. These investments will pay off in the long-run, the report says.
