The Vital Role of Early Warning Systems for Tonga and Small Island Developing States

Early warning systems serve as a lifeline for Small Island Developing States (SIDS). These systems are crucial in providing timely and accurate information to governments, communities, and stakeholders, thereby saving lives and mitigating the socio-economic impacts of disasters. SIDS rely heavily on early warning systems for proactive measures such as evacuation plans, resource allocation, and infrastructure reinforcement. Due to their limited landmass, fragile ecosystems, and narrow resource bases, SIDS are highly vulnerable to extreme weather, rising sea levels, and shifting precipitation patterns. These threats endanger lives and disrupt economies, often displacing communities. Despite their importance, only one-third of SIDS report having such systems, highlighting an urgent need for action to bridge the gap in early warning infrastructure and services.
