【 摘 要 】

Flooding is among the most prevalentnatural hazards affecting people around the world. Thisstudy provides a global estimate of the number of people whoface the risk of intense fluvial, pluvial, or coastalflooding. The findings suggest that 1.47 billion people, or19 percent of the world population, are directly exposed tosubstantial risks during 1-in-100 year flood events. Themajority of flood exposed people, about 1.36 billion, arelocated in South and East Asia; China (329 million) andIndia (225 million) account for over a third of globalexposure. Of the 1.47 billion people who are exposed toflood risk, 89 percent live in low- and middle-incomecountries. Of the 132 million people who are estimated tolive in both extreme poverty (under $1.9 per day) and inhigh flood risk areas, 55 percent are in Sub-Saharan Africa.About 587 million people face high flood risk, while livingon less than $5.5 per day. These findings are based onhigh-resolution flood hazard and population maps that enableglobal coverage, as well as poverty estimates from the WorldBank's Global Monitoring Database of harmonizedhousehold surveys.
