Although we have in our annual EMDAT press conferences emphasized with data, the increase in disasters and in particular floods and cyclones, the jury may still be out on their climate factors as proximate determinants. Also patterns of disaster related mortality and affected patterns are really quite different from the incidence of events. We looked at a set of floods recently and precipitation levels (very informal and admittedly cursory examination) and flooding is not always linked to above average rainfall. I think that population density and urbanization may have much more to do with flooding than unusual precipitation. We have just starting an exercise in mapping population in very high resolution scales over time in flood basins to check this out. Also human impact is badly studied and badly understood. As epidemiologists will point out, understanding risk factors is fundamental for effective prevention. It is very encouraging though to note that the Bank is giving priority to reducing of the impact of natural disasters
