Urban areas are expected to become even more exposed and vulnerable to flooding and other consequences of climate change in the future. However, cost-effective planning of adaptation strategies is very complicated. Cost Benefit Analysis (CBA) is a method that can help decision-makers evaluate adaptation projects and strengthen the basis for making sound investment decisions. A training will be held in Budapest (9-10/5/2019) which explains what CBA is and how it applies to urban flooding and climate change adaptation. If you are a local government or city official, this will help you identify whether it can be used for your adaptation project.
