This book examines water management integration in the Netherlands, Belgium, France, Spain, Italy and Switzerland. It is based on the European research project EUWARENESS. Per country two case studies are considered, to analyze specific regime transitions at water basin level during the last decades. The twelve case studies are discussed within their national context and compared on conditions that are important for regime change towards sustainability. The book also provides theory on water governance, institutional regimes, and property rights, resulting in a tool for monitoring the progress of integrated water management at the basin level in EU member states or other countries. This book follows another volume published with Kluwer Academic Publishers on "The Evolution of National Water Regimes in Europe", edited by Ingrid Kissling-Näf and Stefan Kuks.
