This study introduces a theoretical framework that supports studies of SD implementation in the context of strategic disaster risk management, by defining what SD implies with regard to planning procedures. The framework is based on the procedural SD principles of participation and integration. It was originally developed for,and has shown great value in, the field of water resource management. In-depth interviews with senior risk management researchers indicate that the framework is also applicable to and valuable for disaster risk management studies.To illustrate the application of the framework, a study of the EU Floods Directive in Sweden is summarized with the framework as the basis for the analysis.展开更多
