|Description=Flooding is the most frequent and costly natural hazard, affecting a majority of countries on a regular basis ([[UNISDR, 2011]]) ([[IPCC, 2012]]). Over the past few decades, the economic damage as a result of flooding has increased in most regions, primarily due to a growth in population and wealth in flood-prone areas ([[Bouwer et al., 2010]]; [[UNISDR, 2011]]; [[Barredo et al., 2012]]). | |Description=Flooding is the most frequent and costly natural hazard, affecting a majority of countries on a regular basis ([[UNISDR, 2011]]) ([[IPCC, 2012]]).

The largest changes in economic loss and mortality from flooding are observed in developing countries, although data scarcities are hampering flood risk assessments. In order to evaluate current flood risk as well as possible changes under global change scenarios, there is a demand for rapid cost-effective assessments based on available global data sets. Such assessments are of interest to various users, for example: | The largest changes in economic loss and mortality from flooding are observed in developing countries, although data scarcities are hampering flood risk assessments.

Key policy issues
- How will future flood risk change as a result of socio-economic changes and climate change?
- What would be the impact of floods, in terms of damage and victims, and where are the hot spots?
- What would be suitable adaptation strategies and investment options related to flood risk?
