Abstract In May 2009, the UNISDR system published the 2009 Global Assessment Report on Disaster Risk Reduction (GAR 2009). One component of this report consisted in a global risk analysis. This task was performed by several institutions which join their efforts during two years to achieve a global modelling of hazards. This includes new hazard models for floods, tropical cyclones, landslides, drought and tsunamis as well as re-interpretation of earthquakes hazard. It allowed for the computation of human and economical exposure. A totally new methodology was used to calibrate vulnerability by using a so- called "event per event" analysis. This allowed determining what are the socio-economical and contextual parameters that are associated with human and economical vulnerability. This new methodology allows considering the intensity of each event as well as contextual parameters in order to compute the risk for different natural hazards. Risk maps were produced for four natural hazards (i.e. floods, earthquakes, landslides and tropical cyclones). This was provided at a resolution of 1 x 1 km. This also allow for the computation of an index for comparing the risk level of different countries. Trend in risk were also studied.
