The overall aim of this PhD thesis is to improve our understanding of current and future global coastal flood risk and how adaptation measures can lead to changes in risk. In order to achieve this, the thesis is divided into two parts. The first part of the thesis will focus on assessing the benefits and costs of reducing coastal flood risk using structural, nature-based and hybrid measures. The second part of the thesis will focus on upstream-downstream effects of adaptation on coastal flood risk. The following objectives are established:
1. Assess the benefits and costs of reducing (future) coastal flood risk through structural measures;
2. Assess the benefits and costs of reducing (future) coastal flood risk using nature-based and hybrid strategies;
3. Attribute the costs of adaptation measure to individual risk drivers;
4. Develop a model framework to assess upstream downstream effects due to adaptation measures;
5. Assess these upstream-downstream effects at the global scale.
