| In 2007, 414 natural disasters were reported. They killed 16847 persons, affected more than 211 million others and caused over 74.9 US$ billion in economic damages. Even if a greater diffusion of disaster occurrence across countries was noted, the toll of human impacts remained concentrated across a small number of disasters and countries. Despite no “mega disaster” being reported, the 10 most important disasters in terms of mortality, victims, and damage accounted for 55.6%, 85.2%, and 66.2% respectively of all the reported deaths, people affected, and damages. Last year’s number of reported disasters confirmed the global upward trend in natural disaster occurrence. This upward trend is mainly driven by the increase in the number of reported hydro-meteorological disasters. Hydrological (essentially floods) and meteorological (storms) disasters are the major contributors to this pattern. In recent decades, the number of reported hydrological disasters has increased by 7.4% per year on average. Furthermore, we have witnessed a strengthening of the upward trend in recent years, with an average annual growth rate of 8.4% in the 2000 to 2007 period. |
