Risk identification and assessment

A qualitative or quantitative approach to determine the nature and extent of disaster risk by analysing potential hazards and evaluating existing conditions of exposure and vulnerability that together could harm people, property, services, livelihoods and the environment on which they depend. Performing risk, hazard and vulnerability assessments is a key disaster risk management activity.

This theme covers aspects related to hazard/vulnerability/climate risk assessment, disaster risk modelling and analysis.

Through UNICEF’s open-access GeoSight platform, decision-makers can visualise risk, compare layers, and identify priority areas for action.

The most valuable drone flight is not necessarily the one carried out immediately after a disaster. It may be the routine survey conducted months earlier, documenting a landscape before it changes.

Update

As the climate warms because of heat-trapping pollution, spring is arriving earlier and summer temperatures are lingering later into the fall. As a result, mosquitoes can emerge earlier, remain active longer, and spread disease over a longer season.

Update

As Guam and the Commonwealth of the Northern Mariana Islands (CNMI) braced for impacts from a second super typhoon in less than three months, the Pacific Disaster Center (PDC) joined regional preparedness coordination and relief efforts.

Update

A ‘reasonable worst-case scenario’ suggests need for large-scale movement of populations away from reshaped coast.

Update

Climate models show warmer winters, with precipitation rates staying about the same but producing more rain and less snowpack, which leads to summer drought.
