Exploring water scarcity issues in light of the growing crisis in global water management, this book examines the applicability of water markets. It provides an overview and understanding of the presence of water markets across the globe, analysing the ways in which different countries and regions are grappling with water scarcity.

Why is trade in wholesale water so rare, when markets can actively trade bread, tractors, and electricity? This book shows that water markets fail because of high transaction costs, resulting in inefficient allocations and unpredictable environmental effects. To overcome these obstacles, this book proposes a trading mechanism called a smart market. A smart market is an auction cleared with optimization. A smart market can reduce the transaction costs of water trading, while improving the environmental outcomes. The authors show why a smart market for water is needed, how it would work, and how to implement it. The smart market described here uses a hydrology simulation of the water resource, user bids via the internet, and mathematical optimization, to maximize the economic value of water while meeting all environmental constraints. The book provides the background to understand the smart market for water, and the detail to help the reader start working on its application. The book explores topics such as: Why water should be more expensive near sensitive environmental locations, Ways to set initial allocations of water rights, The role of regulatory oversight, The prerequisites of a water market, and How to counter objections to water markets. The culmination of a decade of investigation, this book combines explanation, examples, and detail to inform policymakers, large water users, environmental organizations, researchers, and a thirsty public.

This book evaluates the history, the present and the future of water markets on 5 continents, beginning with the institutional underpinnings of water markets and factors influencing transaction costs. The book examines markets in seven countries and three different U.S. states, ranging from village-level water markets in Oman to basin wide formal water markets in Australia's Murray-Darling River basin. Introductory chapters on the background of water markets and on transaction costs and policy design are followed by chapter length discussion of water markets as an adaptive response to climate change and of supply reliability in a changing climate. Case studies describe a variety of facets of the design and function of markets around the world: California, Chile, Spain, Oman, Australia, Canada, India and China. In analyzing these real-world examples of markets, the contributors explore water rights and trading of rights between agricultural and urban sectors and the principles and function of option markets. They discuss different sized approaches, from large scale, ministry-level administration of markets to informal arrangements among farmers in the same village, or groups of villages which allocate water without large investment in management and infrastructure. Discussion includes questions of why water market practices have not expanded more rapidly in arid places. The book discusses mechanisms for resolving conflicts between water rights holders as well as between water right holders and third parties impacted by water trades and whether or not public ownership of water rights or use rights should trump private ownership and under what condition. Also covered are new and expanding categories of water use, beyond human consumption, agriculture and industry to new technologies ranging from extracting natural gas from shale to producing biofuels. The book concludes with suggestions for future water markets and offers a realistic picture of how they might change water use and distribution practices going forward.

In 1981 Chile's military government dictated a new Water Code that radically changed the country's previous water rights system by strengthening private property rights, favoring market incentives, and reducing state regulation. Against the Current: Privatization, Water Markets, and the State in Chile is the first empirical and interdisciplinary study of water markets in Chile, which is the leading international example of free market water policies. Against the Current: Privatization, Water Markets, and the State in Chile challenges the glowing reports given by neoliberals in Chile and the World Bank, showing that the results of this economic experiment have actually been rather mixed. Within the agricultural sector the Water Code has worked fairly well, although the market incentives to conserve water have been ineffective and water rights trading has been less active than expected. The Code's impact has been more negative at the level of river basins, where the institutional framework has revealed critical flaws in coordinating multiple water users and resolving conflicts. Against the Current: Privatization, Water Markets, and the State in Chile combines law, political economy, and geography to analyze the disadvantages, problems, and wider contexts of water markets. This book will appeal to everyone interested in property rights, market-friendly environmental policies, the political economy of sustainable development, and the intersection of economics with law and institutions.

Tapping Water Markets is about the past, present, and future of water markets. It compares water markets with political water allocation, documents the growth of water markets, and explores the ways in which water markets can be improved and implemented further. This book provides up-to-date information of where and why water shortages are occurring and where and why water markets are evolving to resolve conflicting water uses. Though the main focus is on the United States, it includes examples from other parts of the world to show how water markets are beginning to thrive. It contains institutional detail that is accessible to people who are not economic or hydrologic experts, and comes alive with numerous examples and case studies of water markets. The book begins with an analysis of water institutions as they have varied over time and location. It then covers a range of discrete water management topics including surface water allocation, groundwater management, environmental flows, and water quality trading. The book concludes with predictions about the future of water scarcity and the ability of water markets to shape that future more positively.

Water is becoming increasingly scarce. If recent usage trends continue, shortages are inevitable. Aquanomics discusses some of the instruments and policies that may be implemented to postpone, or even avoid, the onset of water crises. These policies include establishing secure and transferable private water rights and extending these rights to uses that traditionally have not been allowed, including altering in-stream flows and ecosystem functions. The editors argue that such policies will help maximize water quantity and quality as water becomes scarcer and more valuable. Aquanomics contains many examples of how this is being accomplished, particularly in the formation of water markets and market-like exchanges of water rights.Many observers see calamity ahead unless water supplies are harnessed and effectively conserved, and unless water quality can be improved. It is also clear that declining water quality is a serious problem in much of the world, as increasing human activities induce high levels of water degradation. Those who voice these concerns, argue the contributors to this volume, fail to consider the forces for improvement inherent in market political-economic systems that can address water issues. The contributors see water quality in economically advanced countries as improving, and they believe this establishes the validity of market-based approaches.

Water scarcity is an increasing problem in many parts of the world, yet conventional supply-side economics and management are insufficient to deal with it. One of the key water management options for water demand is water trading. This book explores the role of water trading, as an instrument of integrated water resources management.
