Book excerpt: Governance of global water resources presents one of the most confounding challenges in contemporary natural resource governance. With considerable government, citizen and financial donor attention devoted to a range of international, transnational and domestic laws and policies aimed at protecting, managing and sustainably using fresh and coastal marine water resources, this book proposes that sustainable water outcomes require a ‘trans-jurisdictional’ approach to water governance. Focusing on the concept of trans-jurisdictional water governance the book diagnoses barriers and identifies pathways to coherent and coordinated institutional arrangements between and across different bodies of laws at local, national, regional and international levels. It includes case studies from the European Union, Australia, New Zealand, South Africa, the United States and Southeast Asia. Leading specialists offer insights into the pretence and the promise of trans-jurisdictional water governance and provide readers, including students, practitioners, policy-makers and academics, with a basis for better analysing, articulating and synthesising standards of good trans-jurisdictional water governance both in theory and in practice.
