Whether an earthquake or a tsunami, a hurricane or a flood, the risk that a natural event will develop into a disaster depends only partially on the strength of the event itself. A substantial cause lies in the living conditions of people in the affected regions and the opportunities to quickly respond and help. The Bündnis Entwicklung Hilft (Alliance Development Works) publishes the WorldRiskReport to examine these issues at the global level and to draw conclusions for future actions in assistance, policy and reporting.
