【 摘 要 】

Today, 370 million people live in citiesin earthquake prone areas and 310 million in cities withhigh probability of tropical cyclones. By 2050, thesenumbers are likely to more than double. Mortality risktherefore is highly concentrated in many of the world scities and economic risk even more so. This paper discusseswhat sets hazard risk in urban areas apart, providesestimates of valuation of hazard risk, and discussesimplications for individual mitigation and public policy.The main conclusions are that urban agglomeration economieschange the cost-benefit calculation of hazard mitigation,that good hazard management is first and foremost goodgeneral urban management, and that the public sector mustperform better in generating and disseminating credibleinformation on hazard risk in cities.
