CPB Cost-Benefit Analysis for Flood Risk Management and Water Governance Overview (2017) presents a structured approach to evaluating policies and investments aimed at reducing flood risks and improving water governance. It outlines how cost-benefit analysis (CBA) can be applied to compare alternative measures such as flood defenses, spatial planning, and adaptive strategies.
The report emphasizes the valuation of both direct and indirect impacts, including avoided flood damages, loss of life, environmental effects, and economic disruption. It highlights the importance of incorporating uncertainty, climate change scenarios, and long-term risk into decision-making. Special attention is given to distributional effects, ensuring that costs and benefits across regions and population groups are considered.
Overall, the overview demonstrates that CBA is a critical tool for prioritizing efficient and resilient water management strategies, supporting transparent, evidence-based policymaking in flood risk and governance contexts.
