How does a flood warning, cyclone alert, or heatwave message reach the people who need it most? 🌍
This video breaks down the science, coordination, and community action behind people-centred early warning systems — a cornerstone of disaster risk reduction.
Early warnings save lives. But only when all four pillars work together:
1️⃣ Disaster risk knowledge – analysing hazard, vulnerability, and exposure data to understand who and what is at risk.
2️⃣ Detection, monitoring, and forecasting – using satellites, sensors, and models to anticipate hazards and guide impact-based decisions.
3️⃣ Warning dissemination and communication – ensuring alerts reach everyone through mobile networks, radio, and community systems.
4️⃣ Preparedness and response – enabling communities to plan, practice, and act together, leaving no one behind.
These four pillars protect lives, livelihoods, and futures.
Early Warnings for All is a global initiative to ensure that every person, everywhere is protected by life-saving early warning systems by 2027. ⚠️
