GAR Risk Data Platform

Sources: United Nations Office for Disaster Risk Reduction

The GAR Atlas: Risk Data Platform is an interactive platform that can be read and explored using an IOS or Android tablet. It allows users to visualise, download or extract data on past disaster events, human and economic hazard exposure and risk from natural hazards, in the form of maps, data curves, database tables and excel spreadsheets.

As with the Global Assessment Report on Disaster Risk Reduction, a Global Risk Model has been used to calculate the Annual Average Loss (AAL), a probabilistic risk metric which condenses the multiple interdependencies and complexities that configure disaster risk into a single numerical value. The AAL is presented in this Risk Data Platform, alongside other data that covers the effects of historical disaster events, as well as hazard risk (including likelihood and intensity), and exposure.
Some examples include:

Disaster risk implications – Average Annual Loss (AAL) as per cent of Gross Fixed Capital Formation (GFCF), financing gap return period, size of financing gap, average annual mortality, average annual lost economic production
Data related to the frequency and intensity of hazards – cyclone wind 250 years return period, flood hazard 50/100/200/500/1,000 years
Exposure – exposed population, exposure of capital stock, Gross Domestic Product (GDP), social expenditure
