The issue of adaptation to climate change has become increasingly important in recent years as it is becoming evident that the impacts of human-induced climate change are no longer just a long-term possibility, but are actually a medium-reality probability.

One of the sectors that is likely to be impacted quite severely is the large freshwater systems and river basins. It is therefore important for water-sector policy makers, planners and managers to take into account the possible impacts of climate change on the systems they are managing. In order to do so effectively they will need appropriate tools and methods to enable them to model the potential impacts of climate change and test appropriate adaptation options. This book describes one such effort to develop and test a tool called the Adaptation Methodology for River Basins (AMR). The framework is largely built on existing knowledge, but adapts it to the needs of the water managers. Adaptation in water management is a new issue and adaptation at the basin level is especially difficult. However, it is important that adaptations be considered at the basin level before single-country based projects are developed, in order to avoid making the whole system even more vulnerable to climate change impacts. The book also focuses on adaptations for alleviating impacts for food security and environmental values, with special attention to hydrological and food modelling. I am sure that the book will prove to be a valuable tool for water-sector managers and planners dealing with large river basins to enable them to take into account the potential impacts of climate change and develop adaptation options.
