Flooding is among Vietnam’s most severe natural hazards. Despite recent improvements in early warning systems, challenges remain due to increasingly unpredictable floods driven by climate change, land-use changes, and urbanization. Current limitations include insufficient monitoring equipment, delays in alert delivery, lack of backup communication during outages, and overly technical warning content that communities struggle to interpret. Alerts often fail to provide practical details such as flood arrival time, expected depth, and recommended actions. While multiple information channels exist, they can lead to overload and misinformation. Urban and rural areas differ significantly in flood patterns, infrastructure, and technology access, requiring tailored strategies. This synopsis draws on findings from the “Building Flood Resilience for Communities” project by ISET-International, through the https://zcralliance.org/https://zcralliance.org/, funded by the Z Zurich Foundation, which assessed resilience in 12 communities across Hue city, Gia Lai province (previously Binh Dinh province), and Can Tho city using the FRMC framework.
