This Primer on Integrated Flood Risk Management in Asia is intended to gather together and thereby share the advances in knowledge and experience gained in flood risk management since 1990. There is a gradual shift away from dealing with floods as a stand-alone or one-off event to managing it as part of an integrated water system within a watershed. Current research and literature, partnerships and collaborations, and formation of networks reflect this integrated approach. However, the region lacks a comprehensive resource and reference document for practitioners and professionals, which addresses the complexity of the flood environment in Asia.
