Abstract: Increasing risk of climate change and human induced coastal erosion requires a sophisticated and flexible risk management. The search for effective management methods is illustrated in projects such as Integrated Coastal Zone Management (IZBM) and EUROSION. Research within both projects revealed that holding the responsibility for risk management merely in the hands of responsible authorities is neither effective nor efficient enough anymore. In our approach we seek to combine asset management with risk management of coastal zones. Hereby, it is important to include not only the value of properties, but also the life cycle, tangible and intangible values and social demand in the analysis. On the risk management side we assume a Bayesian approach employing perspectives of risk based upon individual interpretations of risk acceptance. Both risk and benefit can be outweighed in a Spati al Multi-criteria Analysis. This way a stakeholder-based diversi fication of risk can enter a c alculation that provides decision makers with a number of plausible management alternatives. As a result both an increased responsibility among stakeholders, and an increased knowledge base for decision makers can be achieved.
