This document summarizes the presentation given by Kuniyoshi Takeuchi on integrated flood risk management and the progress of integrated water resources management. It provides an overview of the evolution of IWRM from early initiatives in the 1930s to current principles and definitions. It describes integrated flood risk management as a coordinated process to reduce flood risk through structural and non-structural means while maximizing benefits. The presentation highlights the needs for IFRM to operate in a seamless manner across temporal and spatial scales as well as sectors. It showcases the advanced technology of ICHARM's Integrated Flood Analysis System (IFAS) for early warning systems and its applications in various countries through partnerships with local stakeholders.
