FloodAdaptVN: Integrating Ecosystem-based Approaches into Flood Risk Management for Adaptive and Sustainable Urban Development in Central Viet Nam
FloodAdaptVN analyses spatial dynamics of current and future flood risks in the Thừa Thiên Huế province in central Vietnam. The aim is to support urban planning with a newly developed modular information system for sustainable flood risk management.
In central Vietnam, small and medium-sized coastal towns are particularly characterised by a rapid urbanisation trend. The concomitants include extensive surface sealing, the expansion of settlements into flood-prone areas, and a decline in infiltration and retention areas, so that heavy rainfalls lead to enormous surface runoff. Additionally, the narrow and flat settlement area between the inland mountains and the coast only allows very short reaction times to heavy rainfall, which is exacerbated by degraded land and deforestation. Moreover, climate change is expected to lead to stronger and more frequent extreme weather events, such as typhoons with resulting floods in central Vietnam. Such storms cause considerable infrastructural, agricultural, health and economic damage. Due to changing settlement patterns, housing and lifestyles, local vulnerabilities and civil adaptation practices need to be rethought and integrated into planning.
FloodAdaptVN aims to support decision-making processes of local stakeholders in such a way that flood risks in central Vietnam can be minimised by means of adapted risk reduction and adaptation measures. The project team investigates and compares ecosystem-based approaches that can be integrated into flood risk management in the study area for adaptive and sustainable urban development. Implementation aspects for disaster risk reduction are investigated by FloodAdaptVN as well as prioritisation factors for successful risk management.
Innovative aspects of the approach include the assessment of multi-risks on the basis of a chain of effects that reflects local and regional complexities. In addition, future risk scenarios are developed and simulated based on locally adapted climate and socioeconomic scenarios. Finally, a portfolio of adaptation options is identified and assessed, including risk transfer and ecosystem-based approaches. A capacity development strategy is central to the project, which is intended to enable Vietnamese decision-makers to implement successful risk management in the long term and at the same time guarantee a knowledge and experience transfer to the German partners.
