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.

Legal mechanisms for the management, development and protection of water resources have evolved over the years and have reached unprecedented levels of complexity and sophistication. This phenomenon is largely in response to the global community's sustainable development agenda, to the challenges and limitations imposed by climate variability, and to scientific and technological advances. Bringing together diverse experiences from across the world, this book analyses existing water law and governance solutions, their shortcomings, as well as developments and trends in the light of changing circumstances. The legal mechanisms examined range from international treaties, agreements and arrangements on cooperation over transboundary water resources, to the onset of novel issues arising out of technological advances, and from domestic regulation of water abstraction and groundwater management, to domestic regulation of the water industry. The articles in this book were originally published in the journal Water International, following the XIV and the XV World Water Congresses of the International Water Resources Association (IWRA), which were held in 2011 and in 2015, respectively.

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.
