The art and science of communicating risks of natural hazards

Abstract

Every year natural hazards cause significant loss of life and adversely impact development gains by destroying crops, properties and infrastructure. Of all the reported disasters, about 90% are directly or indirectly related to weather and climate. Over the past 50 years vulnerability to disasters has increased as more and more people and assets have been located in areas of high risk. Climate change is expected to increase the frequency and intensity of the most severe weather-related hazards in the decades to come. Identification and communication of risks associated with natural hazards to stakeholders are therefore vital in minimising and mitigating adverse impacts of natural hazards. Success or failure of managing risk associated with natural hazards is dependent on reliable early warning, effective communication and appropriate response mechanism on ground. Early warning of natural hazards lies at the core of the disaster management system. Warning messages are to be simple, containing location- and time-specific useful actionable information to enable proper responses that will help safeguard lives and livelihoods. In near future improved seasonal and climate predictions will help in identifying climatic risks and assist in strategic planning and long-term investments.
