UN Guidelines Issued on Disaster Risk Assessment

16 October 2017

The United Nations International Strategy for Disaster Reduction (UNISDR) has issued a major new set of guidelines on National Disaster Risk Assessment: Governance System, Methodologies, and Use of Results.

Gianluca Pescaroli and David Alexander of the UCL-IRDR Cascading Disasters Research Group authored a section entitled "An introduction to cascading risk and cascading disasters" (pp. 25-31). Their work is referred to in other parts of this report, as cascading risks and impacts are an important cross-cutting issue in disaster reduction. The report can be dowloaded from the UNISDR website at
