Heat Early Warning System in Vietnam: Current status and recommendations
This case study examines the current state of Vietnam’s heat early warning system, including how heat risk is understood and monitored, and how warnings are issued, communicated and acted upon across institutions. It finds that knowledge of heat risk is expanding through research and pilot programmes, but remains fragmented and weakly institutionalised. Vietnam has a structured national temperature-based heat monitoring and forecasting system, supported by a layered warning communication structure, but warnings remain largely generic and insufficiently targeted. Preparedness and response are largely project-driven, with limited formal links between warnings and action, reflecting the emerging but still under-prioritised status of extreme heat as a hazard.
It complements the global report Understanding the Global Landscape of Heat Early Warning Systems and is part of a series of case studies across eight countries in the Zurich Climate Resilience Alliance. Together, the case studies apply a common analytical framework to assess heat early warning systems and identify good practices, gaps and enabling conditions for people-centred, impact-based early warnings for extreme heat.
