This Words into Action guide aims to promote greater implementation of Multi-Hazard Early Warning Systems (MHEWS) across all sectors to protect the most exposed populations from disasters. The COVID-19 pandemic has highlighted the need for integrated solutions that address interconnected risks. Multi-hazard early warning systems (MHEWS) are essential tools for that enable individuals, communities, governments, business and others to take timely action to reduce disaster risks in advance of hazardous events. They are a critical component of comprehensive disaster risk reduction strategies.


MHEWS save lives and provide significant economic benefits, such as reduced damage costs. As an example, with just 24 hours’ notice, MHEWS can reduce damage from hazardous events by up to 30%, and longer lead times offer even broader benefits. Through this guide, key principles and practical steps for establishing and maintaining effective, end-to-end, people-centered MHEWS will be explored, including risk assessment, data management, communication strategies, and community engagement. The public review consultation is now open for the next two months (Closing 15 July).
