Chapter
Climate change and population growth are increasing pressure on urban drainage infrastructure, incrementing the level of flood risk in particular in urban areas. Traditional approaches to cope with urban floods offer low adaptation capacity to the uncertain future. As a response, the use of sustainable drainage measures, also called green infrastru...

Disaster risk reduction is a major concern of small island developing states. Measures to reduce risk should not only be based on the magnitude of physical hazard, but also on the exposure and vulnerability of communities. In this article, we examine flood risk management policies in the Caribbean island of Sint Maarten using coupled agent-based an...
