The Evolution of the Law and Politics of Water presents an overview of global trends in water law and policy and assesses current global water governance. It provides an historic understanding of how and why after 5,000 years of water governance, that governance still has not reached stability. It identifies the key research questions for water law and policy while providing an overview of the current global water governance regime, its evolving characteristics, and the legal theories involved in these changes. It focuses on water law and discusses the characteristics of national, supranational, and international water law through a combination of case studies and thematic chapters. The Evolution of the Law and Politics of Water is the first volume to take a global perspective on the evolution of water law and policy. It describes global patterns and sets forth the particulars of eight national legal systems drawn from every continent and five regional or supranational systems, as well as the body of customary international law as a whole. In particular, it is the first book to explore the interrelation between culture, religion, government and law in water governance and management. The volume is, therefore, a must-read for anyone interested in how water governance has changed through time and in different places as well as anyone interested in how water law has sought to channel water governance through time and in different places and what variables account for the relative success (or lack of success) of water law in performing this channelling function. It is suggestive of possible lines of water law reform and whether a particular reform is likely to be successful.
