Global exposure to river and coastal flooding: Long term trends and changes

► Global assessment of economic exposure to flooding of river and coastal systems. ► Two methods for quantitative assessment, one based on population and one on land-use. ► Analysis conducted for 1970-2050, using global historical spatial data and projections. ► Economic flood exposure is simulated to increase by circa 200% between 2010 and 2050. ► Growth of human population and economic value in flood zones higher than overall growth.
