The Aqueduct Global Flood Analyzer is a web-based interactive platform which measures river flood impacts by urban damage, affected GDP, and affected population at the country, state, and river basin scale across the globe. It aims to raise the awareness about flood risks and climate change impacts by providing open access to global flood risk data free of charge. Find out more at www.wri.org/floods

2. Why Do River Floods Matter?
1. SCALE Floods affect more people than
any other natural disaster
2. DAMAGE Floods from rivers cause as
much or more damage in some countries
as rising seas, storm surges.
3. RISKS RISING 21 million people at risk
now – 54 million expected in 2030.

3. Key Findings
1. POPULATION: 21 million people
worldwide currently at risk – 54 million
projected in 2030
2. GDP: $96 billion at risk currently -- $521
billion projected by 2030
3. TOP COUNTRIES: India, Bangladesh,
China, Vietnam, Pakistan.
