This book will first present a synthesis of hydrometeorological extreme events and their impacts on society; it will then show how societies are organizing themselves to face these extreme events. It will focus on the strategies of integration of risk management in governance and public policy. Theory will be systematically illustrated by real-life success stories of multilevel governance. The book will focus on several governance dimensions: individuals involved in extreme events at various decision-making systems, strategies and policy instruments, and also the resources mobilized in decision-making processes. Global initiatives such as the Sendai Framework for Disaster Risk Reduction (2015-2030) adopted at the Third UN World Conference in Sendai, Japan in March 2015 will be referenced; as well as supporting a vision of possibilities as developed by the working group on climate change of the Common Implementation Strategy of the Water Framework Directive. This book is unique because it focuses on success stories of multilevel governance decision-making processes for managing hydro-meteorological extreme events at catchment scales. It will include the results of several EU-funded projects addressing hydrometeorological extreme events such as CLIMB, STARFLOOD and INTERREG IVB project DROP. This will be the first book dedicated to hydrometeorological extreme events governance based on field investigations from EU research projects, and the first to deal with "multi-hazards" (different types of hydrometeorological hazards), mixing policy, governance and field investigations main outputs, in a single volume. Previously published books have dealt with specific hazards, e.g. floods, droughts or adaptive governance and ecosystem services. The book is part of the Hydrometeorological Extreme Events series, edited by Professor Philippe Quevauviller.
