Abstract
The study provides an economic valuation of creating a concrete sea dike system to counter the impacts of a rise in sea level. Based on the net present value (NPV) decision rule, results indicate that dike options should be recommended as an appropriate adaptation measure for the Vietnamese Mekong Delta (VMD)’s particular geographic situation. Of the dike alternatives applicable to the VMD, initially small-scale dikes that can be subsequently heightened should be a priority choice.
