Abstract
<p> Sea level rise due to climate change poses a serious threat to human populations in coastal areas. Consequently, it is important to consider the potential economic risks and the cost of adaptation within the context of climate change. To this end, coastal regions can be protected more efficiently and economically by employing adaptation measures that combine mangrove afforestation (green infrastructure) and dyke construction (grey infrastructure) in areas considered to be at risk of inundation and flooding. The authors analyzed the costs of gray and green infrastructure developments at locations in Vietnam and the Philippines that differed with respect to population distribution and urban/rural status. However, there are areas where combinations of green and grey infrastructures have been employed along the same coastline. This paper therefore examined the assumptions underlying the implementation of specific inundation protection measures, as well as the costs associated with dykes and multiple protection measures along the same coastline. The findings showed that multiple protection measures that incorporate mangrove forests can reduce the number of dykes required and costs of adaptation.</p>
