This book provides a comprehensive review of the state of international law as it applies to transboundary groundwater resources and aquifers. The main focus is on recent developments and the emerging international law for transboundary aquifers as reflected in the practice of states and the work of the UN International Law Commission, UN Economic Commission for Europe, and International Law Association. The author takes an interdisciplinary approach to the subject matter and provides the scientific hydro-geological underpinning for the application of law and policy to transboundary groundwater resources. He also addresses the growing global dependence on this hidden resource, as well as both the historical and scientific context for development of the law. The book provides case examples throughout to illustrate the various concepts and developments. These include more detailed examinations of the few existing transboundary aquifer agreements in operation, such as for aquifers between France and Switzerland and Jordan and Saudi Arabia, as well as aquifers in North Africa and in South America.

Groundwater amounts to 97% of available global freshwater resources. Emphasising the crucial importance of this in the context of increasing population, climate change and the overall global water crisis, Francesco Sindico offers a comprehensive study of the emerging body of international law applicable to transboundary aquifers.

Effectively managing increasingly scarce transboundary water resources in many parts of the world may become one of the most critical challenges facing the international community in the 21st century. Global warming is expected to exacerbate the existing problems of water scarcity in Africa, the Middle East and Central Asia, and threatens to affect even relatively water-secure regions and countries. Global freshwater resources are shrinking at an increasing pace. Forty percent of the world's population depends on transboundary water resources, a situation that raises serious concerns at the international level. Unresolved issues of water resource use and allocation may create the potential for serious interstate conflicts and undermine regional stability. It is imperative that existing and potential disputes over access to shared water resources are resolved through peaceful means within the framework of legal principles and norms provided by international law. While not yet in force, the 1997 UN Convention on the Law of the Non-Navigational Uses of International Watercourses codifies a number of rules of customary law that apply to international watercourses. However, even in the absence of a universally ratified instrument there is a body of international rules widely acknowledged as an authoritative statement of international law governing international watercourses - the International Law Association (ILA) rules on the law of international water resources. The present book, which contains the complete collection of the ILA rules on international water resources, together with comments, explanatory notes and other supporting materials, will be of significant academic and practical value to the range of experts working in this field. There is no doubt that legal scholars and researchers will find this book very helpful in discovering the conceptual underpinings and the evolution of international water law. For the practitioners, this collection will serve as a useful reference tool containing a wealth of 'black letter' normative material.

Groundwater is humanity's most vital supply of freshwater. Freshwater resources contained in aquifer systems globally are two orders of magnitude greater than those found in all rivers, lakes, and other surface freshwaters combined. Moreover, approximately one half of the world's population today is dependent on groundwater for its basic needs. While these truisms are widely acknowledged, an additional reality is now recognized - many of these subsurface freshwater reservoirs are actually transboundary formations shared amongst two or more nations. In fact, around 600 transboundary aquifers have been identified worldwide. They underlie the territory of nearly every non-island nation and are found in both humid and arid environments. Surprisingly, though, only a handful of transboundary aquifers worldwide are subject to any type of formal or informal international agreement. Transboundary groundwater resources are now receiving growing attention among the international community. Questions are being raised about how they should be managed, allocated and protected, what rights aquifer riparians can enjoy, and what responsibilities these aquifer states might owe to neighbouring aquifer riparians. This book considers all these various aspects of the management and regulation of transboundary groundwater resources. It also presents case studies and explores recent efforts to engage the international community on best practices and global standards for governing transboundary aquifers. As communities and nations continue to expand their reliance on these critical sources of freshwater, they will have to address such issues and develop governance regimes for these shared subsurface resources. The chapters in this book were originally published as a special issue of Water International.

In International Groundwater Law and the US-Mexico Border Region, Maria E. Milanes provides a study and analysis of the international groundwater law. The regulation and groundwater management along the US-Mexico border reflect the current international trends for management of transboundary groundwater. International Groundwater Law and the US-Mexico Border Region offers a new international legal and institutional framework to manage fossil aquifers and groundwater in conjunctive use with surface water, where specific guidelines and recommendations for water banking can improve water allocation and protect the environment. This framework can be adapted to any region of around the world. The US-Mexico border is the case study selected to apply and demonstrate the efficacy of this legal and institutional framework.
