Climate change has been intensifying extreme rainfall resulting in unprecedented floods, landslides and debris flows all over the world, even where people have never experienced this before. How can we manage such flood-related hazards? This book presents recent conceptual developments in disasters, risk, and resilience; and surveys UN policies on environment and development, and on disaster management. Sustainable and resilient development requires an integrated approach and human empowerment. Japan provides a useful example of effective flood management and disaster recovery, in its current strategies for river and basin integrated flood management.
