This book examines recent developments in river (flood) management from the viewpoint of Making Space for the River and the resulting challenges for water governance. Different examples from Europe and the United States of America are discussed that aim to 'green' rivers, including increasing river discharge for flood management, enhancing natural and landscape values, promoting local or regional economic development, and urban regeneration. Making Space for the River presents not only opportunities and synergies but also risks as it crosses established institutional boundaries and touches on multiple stakeholder interests, which can easily clash. Making Space for the River helps the reader to understand the policy and governance dynamics that lead to these tensions and pays attention to a variety of attempts to organize effective and legitimate governance approaches. The book helps to realize connections between policy domains, problem frames, and goals of different actors at different levels that contribute to decisive and legitimate action. Making Space for the River has an international comparative character that sheds light upon both the country-specific governance dilemmas which relate to specific state traditions and institutional characteristics of national water management, but also uncovers interesting similarities which provide us with building blocks to formulate more generic lessons about the governance of Making Space for the River in different institutional and social contexts. The authors of this book come from a variety of disciplines including public administration, town and country planning, geography and anthropology, and these different disciplines bring multiple ways of knowing and understanding of Making Space for the River programs. The book combines interdisciplinary scientific analyses of Space for the River projects and programs with practical knowing and lessons-drawing. Making Space for the River is written for both practitioners and scholars and students of environmental policy, spatial planning, land use and water management.
