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.

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.

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 represents about 97 per cent of the fresh water resources available on earth (excluding the water locked in the polar ice), and is of key social, economic, environmental and strategic importance. Aquifers (including numerous transboundary ones) are coming under growing pressure from over-abstraction and pollution, which seriously threaten their sustainability. This publication brings together a range of binding and non-binding international law instruments dealing with groundwater, an emerging body of rules that indicate a trend towards more comprehensive international regulation in this important field.

This book analyses the legal challenges facing international cooperation on water management in the twenty-first century.

The Research Handbook on International Water Law surveys the field of the law of shared freshwater resources. In some thirty chapters, it covers subjects ranging from the general principles operative in the field and international groundwater law to the human right to water and whether international water law is prepared to cope with climate disruption. The authors are internationally recognized experts in the field, most with years of experience. The Research Handbook is edited by three scholars and practitioners whose publications and work deal with the law of international watercourses.

This book from the NATO ASI on "Overexploitation and Contamination of Shared Groundwater Resources Management, (Bio)technological, and Political Approaches to Avoid Conflicts" is written by authors from different disciplines and regions of the world. The aim of the book is to contribute to the knowledge of shared groundwater resources management to avoid conflicts by considering multi-disciplinary approaches based on effective and equitable water sharing for all water users.
