The continued significant impacts of disasters from natural hazards raise questions regarding the epistemic commensurability of measures recommended to achieve substantial disaster risk reduction. Using the case of Flood Risk Reduction (FRR), this study critically reviews key scientific literature on the epistemic foundations of the indigenous, scientific, and integrated knowledge perspectives to disaster risk reduction. Results suggest that the adoption of measures for FRR is determined by how related or detached, in their lived experiences, communities-at-risk are from the perspective into which measures are framed. Yet the increasingly recommended integrated knowledge perspective rarely grasps lived experience. Therefore, an extension of the integrated knowledge perspective is proposed based on an analogy with the philosophical theory of hylomorphism to derive a hylomorphic framework. This framework elaborates how appropriate knowledge integration for FRR should be founded at a composite of two intrinsic elements: the indigenous lived experience of a specific flood prone context (i.e., the hyle) and the context-specific flood risk science (i.e., the morphe).

自然灾害对灾害造成的持续重大影响使人们对为实现减少灾害风险而建议采取的措施的认识上可比性提出了质疑。本研究以减少洪水风险（FRR）为例，对有关减少灾害风险的本地，科学和综合知识观点的认识基础的关键科学文献进行了严格的评论。结果表明，FRR措施的采用取决于风险措施社区在其生活经验中与措施框架之间的相关性或分离性。但是，越来越多地推荐使用集成知识的观点很少能抓住实际经验。因此，基于与人类哲学理论的类比，提出了综合知识观点的扩展。同构来导出同构框架。该框架详解如何为FRR适当的知识整合应以合成两个内部因素来建立：具体的洪水多发情况下（即土著生活经验hyle）和特定情境的洪水风险的科学（即morphe） 。
