DECIDER: DECisions for Adaptive Pathway Design and the Integrative Development, Evaluation and Governance of Flood Risk Reduction Measures in Transforming Urban-Rural-Systems


Fachgebiet: Allgemeine Geographie, Geographische Entwicklungsforschung, Geographische Gesellschaft-Umwelt-Forschung, Regionale Geographie, Stadtgeographie
Gefördert durch: Bundesministerium für Bildung und Forschung (BMBF) - CLIENT II

Projektleitung: Prof. Dr. Matthias Garschagen
Projektwissenschaftler: M.Sc. Jiachang Tu, Dr. Liang Emlyn Yang

Laufzeit: 05/2019 - 04/2023

Background and Challenges

  • >> Increasing flood risks in coastal megacities due to combined impacts of climate change and fast urbanization
  • >> Lack of practical tools to assess concurrent flood adaptation options and potential pathways
  • >> Low political will and inadequate institutional structures to promote flood adaptations and resilience building
  • >> Lack of integrative understanding on risky scenarios of both climatic change and future urbanization trend in Vietnam
  • >> Few referable cases on flood risk reduction in the fast growing coastal megacity HCMC


Innovative Solutions

  • >> Adaptive development pathways
  • >> Decision supporting system (DST)
  • >> Integration of different climatic, environmental, economic, social and political aspects
  • >> Transfer of adaptation knowledge and practical tools among similar cities

Work Plan

DECIDER combines the estimation of future risk and adaptation pathways as well as the collection, comparison and evaluation of different adaptation options to reduce the flood risk. Eventually, the methods will be transferred to a practical Decision Support Tool.

     

In implementation, DECIDER is divided into a total of six work packages (WPs), each with up to four sub-work packages, which are closely linked by data streams and collaborations. The work packages are shown schematically in the following graph.



Research Objectives

DECIDER aims at developing knowledge-based solutions for the design, evaluation and implementation of robust, yet adjustable, adaptation pathways in the context of increasing flood risk in transforming rural-urban-systems. The project uses Ho Chi Minh City (HCMC) and its hinterland as a pilot, yet, it aims at facilitating a wider transfer of the results, methods and tools to other coastal cities with similar adaptation pressure (e.g. Bangkok, Dhaka, Jakarta).

     

There are three sub-objectives:

  • >> Developing and testing innovative methods for integrative assessment of future risk pathways considering future trends in exposure and social vulnerability driven by socio-economic change processes
  • >> Developing and testing integrative methods for multidimensional evaluation of various adaptation options, taking into account previously under-represented factors, e.g. social acceptance or political feasibility
  • >> Development of a decision support system (DST) for the generation of sustainable adaptation pathways in the high-risk and dynamic HCMC as well as beyond the project duration for other coastal cities
