A framework for evaluation of flood management strategies

Area of Science:

• Disaster Risk Management
• Economic Resilience
• Environmental Policy

Background:

• Societal disaster impact correlates with pre-disaster economic strength, particularly affecting developing nations.
• Effective disaster preparedness requires robust institutional systems for prevention, early warning, and mitigation technologies.
• Existing disaster modeling approaches lack integration between event analyses and strategy models.

Purpose of the Study:

• To extend a loss-sharing framework from emerging economies to developing countries, addressing their higher vulnerability.
• To identify and analyze key parameters for formulating effective flood risk management strategies in developing regions.
• To propose a functional framework for disaster loss distribution applicable to developing and emerging economies.

Main Methods:

• Analysis of policy strategies for flood loss sharing, initially developed in Hungary's Tisza case study.
• Extraction of key parameters from stakeholder interviews within the studied region.
• Adaptation and application of the framework to northern Vietnam as a representative developing region.

Main Results:

• Identification of critical parameters influencing flood strategy formulation in developing economies.
• Development of a proposed framework for disaster loss spread, tailored for developing and emerging economies.
• Demonstration of the framework's adaptability using a case study from northern Vietnam.

Conclusions:

• The proposed framework facilitates better disaster preparedness by integrating loss-sharing strategies.
• The parameter set can be incorporated into simulation and decision models for policy evaluation with multiple stakeholders.
• Extending the framework to developing countries is crucial due to their heightened vulnerability to hazardous events.
