Evaluation of PreventionWeb and related UNISDR information services for disaster risk reduction

Itad conducted an evaluation of PreventionWeb, the UN's International Strategy for Disaster Reduction's knowledge portal.


PreventionWeb ( is the United Nations International Strategy for Disaster Reduction’s (UNISDR) knowledge portal ‘serving the information needs of the disaster reduction community’.

Our approach

Our evaluation combined a technical usability assessment of the website with a broader remit to ‘position’ UNISDR’s strategy to respond to future Disaster Risk Reduction (DRR) needs and target audiences.  The evaluation was based around a theory of change approach whereby PreventionWeb’s objective to coordinate DRR knowledge and information was placed in the context of a higher order development outcome – the behavioural change expected of UNISDR’s priority audience. We presented the evaluation’s final report to the UNISDR Special Representative to the Secretary General for DRR in Geneva.
