Climate change is a potential threat to Vietnam's development as current and future infrastructure will be vulnerable to climate change impacts. This paper focuses on the physical asset of road infrastructure in Vietnam by evaluating the potential impact of changes from stressors, including: sea level rise, precipitation, temperature and flooding. Across 56 climate scenarios, the mean additional cost of maintaining the same road network through 2050 amount to US$10.5 billion. The potential scale of these impacts establishes climate change adaptation as an important component of planning and policy in the current and near future

The Development under Climate Change research effort provides a basis for determining quantitative impacts on infrastructure from climate change. This paper provides results of an analysis of sea level rise impacts on road infrastructure in Vietnam. The study utilizes a quantitative approach for determining these impacts through engineering-based models that estimate the impact of sea level rises on road infrastructure. Through this approach, the cost impact of sea level rises on the coastal regions of Vietnam are presented

This paper presents the results of the current study on the impact of climate change on the road and building infrastructure within South Africa. The approach builds upon previous work associated with the UNU-WIDER Development under Climate Change effort emphasizing the impact of climate change on roads. The paper illustrates how climate change effects on both road and building structures can be evaluated with the application of a new analysis system - the infrastructure planning support system. The results of the study indicate that the national level climate change cost impact in South Africa will vary between US141.0millionaverageannualcostsinthemedianclimatescenariounderanadaptationpolicy,andUS210.0 million average annual costs under a no adaptation scenario. Similarly, the costs will vary between US457.0millionaverageannualcostsinthemaximumclimatescenariounderanadaptationpolicyscenario,andUS522.0 million average annual costs under a no adaptation scenario. The paper presents these costs at a provincial impact level through the potential impacts of 54 climate scenarios. Decadal costs are detailed through 2100
