This book describes the existential threats facing the global water systems from population growth and economic development, unsustainable use, environmental change, and weak and fragmented governance. It argues that 'business-as-usual' water science and management cannot solve global water problems because today's water systems are increasingly complex and face uncertain future conditions. Instead, a more holistic, strategic, agile and publically engaged process of water decision making is needed.Building Resilience for Uncertain Water Futures emphasises the importance of adaptation through a series of case studies of cities, regions, and communities that have experimented with anticipatory policy-making, scenario development, and public engagement. By shifting perspective from an emphasis on management to one of adaptation, the book emphasizes the capacity to manage uncertainties, the need for cross-sector coordination, and mechanisms for engaging stakeholder with differing goals and conflict resolution. This book will be a useful resource for students and academics seeking a better understanding of sustainable water use, water policy and water resources management.
