Ensuring Robust Flood Risk Management in Vietnam

Background

Ho Chi Minh City (HCMC) ranks fourth globally among port cities most vulnerable to climate change. It already experiences extensive routine flooding, but rising sea levels could permanently inundate a large portion of the city’s population, place the poor at particular risk, and threaten new economic development that has occurred in low-lying areas.

Goals

In this World Bank-sponsored project, RAND researchers worked with the HCMC Steering Committee for Flood Control (SCFC) to use robust decision making (RDM) to develop long-term flood defenses that will be robust to these uncertainties. RAND researchers traveled to HCMC and met with key stakeholders including the SCFC and local World Bank officers in order to understand the city’s flood concerns, existing infrastructure, and current planning efforts, as well as to present RDM.

Outcome

RAND developed a design of the analysis of vulnerabilities, adapted the SCFC's models for this analysis, identified vulnerabilities, and evaluated adaptation options to develop a robust, iterative risk management plan. Researchers also presented their findings and recommendations at a workshop in HCMC.

    Flood Risk Management in Ho Chi Minh City

    Jul 22, 2013

    Ho Chi Minh City faces significant and growing flood risk. Recent risk reduction efforts may not work if climate and socio-economic conditions diverge from earlier projections. Robust decisionmaking can help Vietnam's capital develop integrated flood risk management strategies despite this uncertainty.
