The ongoing implementation phase of FloodAdaptVN (2025–2027) translates the completed research and development phase into practice – from scientific results to effective flood risk management in Huế City. The central focus is supporting local partners in integrating the developed information products, concepts, and the FRAME WebGIS system into risk-informed planning processes. The consortium works closely with the Provincial Committee for Natural Disaster Prevention and Control (CCNDPC) and the Smart City Monitoring and Control Centre (SCMCC) to embed FRAME institutionally within existing decision-making structures. Working with local stakeholders, adaptation pathways are being co-created that bundle ecosystem-based, structural, and social measures to achieve long-term climate resilience for Huế. Solution Labs provide a structured framework for translating scientific findings into concrete planning recommendations. Capacity development is a further key priority: technical training courses, a Train-the-Trainers programme at Hue University, and support for local business capacities lay the groundwork for the sustainable use of the tools developed. In parallel, project results – especially FRAME – are being transferred to other cities in central Vietnam and fed into national planning frameworks. The phase also strengthens German-Vietnamese knowledge exchange, with lessons from extreme flood events in both countries informing each other’s practice. With its activities, FloodAdaptVN is working to establish Huế as a model city for climate resilience in Vietnam – with transferable impact for Southeast Asia and beyond.

Huế, a rapidly growing coastal city in central Vietnam, faces severe flood risk driven by surface sealing, the loss of retention areas, and the very short response times imposed by its narrow setting between mountains and coast. Climate change is further increasing the frequency and intensity of typhoons and extreme rainfall. Against this backdrop, the completed research and development phase of FloodAdaptVN (2021–2025) applied a transdisciplinary approach combining hydrological and hydraulic modelling, Earth observation, socio-economic vulnerability assessments, and participatory co-design processes. This produced high-resolution flood hazard maps and scenario-based risk assessments for 2030, 2050, and 2100, incorporating climate projections (RCP) and socio-economic development pathways (SSP). A catalogue of 18 ecosystem-based adaptation measures was developed and evaluated through cost-benefit analyses. Household surveys with over 640 participants provided in-depth insights into local vulnerabilities, risk perceptions, and adaptation capacities. All results were integrated into the FRAME WebGIS system. Findings are documented in the Risk Report, the Adaptation Report, and a Summary for Policymakers, all available on the project website.
