Tóm tắt: Flooding is one of the most significant natural disasters to affect Vietnam. This is due to the high frequency of floods in the country and the severe impact they have on agriculture, transportation, water resources, infrastructure and human lives. Floods are a particularly significant problem for households living in low-lying areas such as the district of Quang Dien in Thua Thien Hue province. Projections show that the frequency and severity of floods in Thua Thien Hue will increase in the future due to climate change. Flood depths and inundation areas are also projected to increase significantly. To deal with current flood problems, local communities and government agencies design and implement various adaptation options. This study examines the economic feasibility of upgrading the flood control system in the An Xuan tributary basin in Quang Dien district, Thua Thien Hue province. This assessment is made using a cost-benefit analysis (CBA), in which the costs and benefits of the project were identified and valued using different valuation methods. --- The findings show that upgrading the flood control system of the An Xuan tributary basin would help communities and households avoid the damages that floods cause to their livelihoods, houses and assets. The adaptation project would also help reduce damages to infrastructure, increase the net benefit of rice production and avoid the cost of social disruption caused by floods. The benefits of the project were valued using both a market-based method and the contingent valuation method (CVM). The change in flood risk due to the adaptation option, and the reduction in the probability of inundation that it would bring, were taken into consideration when calculating the costs and benefits of the adaptation project. --- The CBA results show that the adaptation is economically feasible (although the estimated values of its benefits using the two valuation methods were not the same, with the CVM giving the bigger value). Upgrading the entire An Xuan tributary would bring great benefits to households and the government and would make good policy sense in light of the potential impact of climate change on future rainfall and sea levels. In other words, because the frequency and intensity of floods is set to increase (along with expected sea level rises), they will cause even more damage to communities than they do now if the An Xuan tributary is not upgraded. This means that it is really worthwhile for the government to invest in this project, as it will increase the sustainability of both agricultural production and socio-economic development. Besides, given the potential economic benefits that it will bring to communities, upgrading the entire An Xuan tributary will also make a significant contribution to sustainable agricultural water management and will improve sanitation conditions.
