Bridges over Water places the study of transboundary water conflicts, negotiation, and cooperation in the context of various disciplines, such as international relations, international law, international negotiations, and economics. It demonstrates their application, using various quantitative approaches, such as river basin modeling, quantitative negotiation theory, and game theory. Case-studies of particular transboundary river basins, lakes, and aquifers are also considered.This second edition updates the literature on international water and in-depth analyses on political developments and cooperation between riparian states. With an appended chapter on principles and practices of negotiation, and a new case study on the La Plata Basin, this edition is a timely update to the field of transboundary water studies.

Climate change, population growth and the increasing demand for water are all capable of leading to disputes over transboundary water systems. Dealing with these challenges will require the enhancing of adaptive capacity, the improving of the quality of water-resources management and a reduction in the risk of conflict between riparian states. Such changes can only be brought about through significant international cooperation. Christina Leb's analysis of the duty to cooperate and the related rights and obligations highlights the interlinkages between this duty and the principles of equitable and reasonable utilisation and the prevention of transboundary harm. In doing so, she considers the law applicable to both international watercourses and transboundary aquifers, and explores the complementarities and interaction between the rules of international water law and the related obligations of climate change and human rights law.

As demand for fresh water rises, together with population, water scarcity already features on the national security agenda of many countries. In this book, Dinardevelops a theory to explain solutions to property rights conflicts over shared rivers. Through systematic analysis of available treaty texts, corresponding side-payment and cost-sharing patterns are gleaned. Geographic and economic variables are used to explain recurring property rights outcomes. Rather than focusing on a specific river or particular geographic region, the book analyzes numerous rivers, dictated by the large number of treaty observations, and is able to test several hypotheses, devising general conclusions about the manner in which states resolve their water disputes. Policy implications are thereby also gained. While the book simultaneously considers conflict and cooperation along international rivers, it is the focus on negotiated agreements, and their embodied side-payment and cost-sharing regimes, that justifies the use of particular independent variables.
