Project title: Climate change risk assessment and adaptation for loss and damage of urban transportation infrastructure (UTI) in Southeast AsiaProject Reference: CAF2013-07RR-Huong; CAF2015-RR09-CMY-Huong Project initiative: APN Climate Adaptation Framework: Climate Change Adaptation, Disaster Risk Reduction & Loss + DamageProject summary:Climate change (CC) will potentially have negative impacts on urban transportation infrastructure (UTI) in Southeast Asia, and improved understanding of CC loss and damage, as well as the linkages between hazards, vulnerabilities adaptive capacity, is critical. However, there is a shortage of practical methods for estimating loss and damage in the context of CC and urbanization and particularly for UTI. UTI management is a complex issue and there is limited knowledge of how to incorporate appropriate adaptation measures and strategies into urban transport planning at the city level. This research presents results and experiences of rapid assessment that were conducted in six cities located in three countries including Vietnam, Cambodia and Thailand for current CC loss and damage of UTI. One pilot city from One pilot city from each country was selected for assessment by applying NK-GIAS to determine loss and damage for urban roads. The RVA results showed that the six selected cities are highly vulnerable to CC due to their geographic location, SLR, storm surge, flood, and salinity intrusion. CC threats to UTI are especially related to road damage. It was interestingly found that through application of NK-GIAS, economic losses for each flood scenario were determined, showing how increasing flood depth increased damage costs in each city. Further studies are recommended to develop appropriate damage curves through laboratory analysis, addressing both flood depth and duration, to strengthen NK-GIAS analyses.Countries involved: Vietnam, Thailand, Cambodia,
