Assessing the myth of disaster risk reduction in the wake of catastrophic floods

Whether disasters serve as focusing events leading to measures that reduce future disaster risks is contested. Here, we study flood disasters in 23 of the world’s most flood-prone countries to assess whether catastrophic floods, those milestone events with the highest fatalities, have been followed by decreasing mortality in subsequent floods. Results from a trend analysis, controlling for flood magnitude and subtypes, find that reductions in mortality rates have rarely followed the most devastating floods.
