The report systematically considers a country's vulnerability and its exposure to natural hazards to determine a ranking of countries around the world based on their natural disaster risk. The WorldRiskIndex (WRI), developed by the Institute for Environment and Human Security (EHS) of the United Nations University (UNU) and Bündnis Entwicklung hilft (BEH), is the main feature of the WorldRiskReport (WRR). It determines the risk of becoming a victim of a disaster as a result of vulnerability and natural hazards such as earthquakes, volcanic eruptions, storms, floods, droughts and sea level rise for 172 countries worldwide. The WRI is based on 28 indicators and research data which are globally freely available and results in a global risk ranking and maps which allow for comparison between countries. Risk is at its highest where a high level of exposure to natural hazards coincides with very vulnerable societies.
