Global Risk And Vulnerability Index Trends per Year (GRAVITY) Phase IV: Annex to WVR and Multi Risk Integration


Duration: May 2003 - May 2003

The purposes of the Disaster Risk Index was to identify whether global data sets could be used for identifying population living in exposed areas and demonstrate the link between socioeconomical parameters and vulnerability. The level of correlation achieved delineates that both physical exposure and variables tested are significant and could be used for categories of risk identification. The correlation found is even much higher than initially thought. This is particularly true for climatic events. Smaller correlation was achieved with earthquakes, this is believed to be due to the long returning period, which is less compatible with the 21 year period observed.
