How policy-makers and society deal with uncertainty is a key issue for NH/DRR.

Uncertainty is present with respect to quantification and qualification of the biophysical and social impacts associated with natural hazards.

For example, uncertainty exists concerning the climatic drivers that can trigger natural hazards since many feedback loops in earth systems are not yet well understood.

Likewise, uncertainty in social responses to natural hazards contributes to social vulnerability.

As a result, uncertainties related to the occurrence of natural hazards must be addressed in an integrated and transparent way to cope with bio-physical and social impacts and avoid an undesired lack of appropriate action.
To increase preparedness and decrease response times to natural hazard risk, uncertainties must be identified and mapped. Only when uncertainties are made transparent, can policy-makers devise measures that take uncertainties into account.
