This book deals with the economic modelling of water at the global, national and sub-national levels. It presents a multi-faceted analysis and, while it outlines the theories behind various models, its main purpose is to analyse policy issues and present insights arising from modelling, including a chapter analysing the macroeconomic implications of climate change. Arguably the most compelling reason for publishing a book on the economic modelling of water arises from the fact that agriculture accounts for approximately 70% of water used for economic purposes, while only contributing 4% of global income. Given that water is an essential commodity, this discrepancy may in part be symptomatic of an undervaluation of water due to immature and incomplete markets. In turn, this undervaluation has led to an ongoing misallocation of water. When economic models include water accounts that feed into production functions, they model impacts on the marginal product of water. Policies that improve the link between the marginal product and price of water will improve water allocation, while advanced economic models such as those presented here can enhance our ability to explore the possible impacts of improved policy.

Korea was the first non-G7 member and Asian country to host the recent G20 Summit, acting as a bridge between advanced and developing nations. At the G20 Seoul Summit, green growth as well as development and a global financial safety net were on the agenda. Against this backdrop, the aim of this book is to comment on and suggest how to go about setting agendas and shaping further discussions of future summits. The book consists of three major parts: the first part discusses the role of G20 in reforming international monetary system, the status of the IMF since the European sovereign debt crisis, the use of the yuan as the world’s reserve currency, and the establishment of a more resilient global financial system. The second part examines trade measures in times of volatile energy prices, the impact of merchandise price volatility on the G20 economies, the EU’s pricing policies and the world’s price volatility, high oil prices and Russia, and oil markets in South America. The third part reviews G20’s financing for green growth, green growth and sustainable development within the G20 framework, and G20’s role in addressing climate change and green growth. This book offers an in-depth review of major issues discussed at the recent summits and will be of interest to policy makers.

Global food price spikes in 2008 and again in 2011 coincided with a surge of political unrest in low- and middle-income countries. Angry consumers took to the streets in scores of nations. In some places, food riots turned violent, pressuring governments and in a few cases contributed to their overthrow. Foreign investors sparked a new global land rush, adding a different set of pressures. With scientists cautioning that the world has entered a new era of steadily rising food prices, perhaps aggravated by climate change, the specter of widespread food insecurity and sociopolitical instability weighs on policymakers worldwide. In the past few years, governments and philanthropic foundations began redoubling efforts to resuscitate agricultural research and technology transfer, as well as to accelerate the modernization of food value chains to deliver high quality food inexpensively, faster, and in greater volumes to urban consumers. But will these efforts suffice? This volume explores the complex relationship between food security and sociopolitical stability up to roughly 2025. Organized around a series of original essays by leading global technical experts, a key message of this volume is that actions taken in an effort to address food security stressors may have consequences for food security, stability, or both that ultimately matter far more than the direct impacts of biophysical drivers such as climate or land or water scarcity. The means by which governments, firms, and private philanthropies tackle the food security challenge of the coming decade will fundamentally shape the relationship between food security and sociopolitical stability.

As globalization links economies, the value of a country's irrigation water becomes increasingly sensitive to competitive forces in world markets. Water policy at the national and regional levels will need to accommodate these forces or water is likely to become undervalued. The inefficient use of this resource will lessen a country's comparative advantage in world markets and slow its transition to higher incomes, particularly in rural households. While professionals widely agree on what constitutes sound water resource management, they have not yet reached a consensus on the best ways of implementing policies. Policymakers have considered pricing water - a debated intervention - in many variations. Setting the price 'right,' some say, may guide different types of users in efficient water use by sending a signal about the value of this resource. Aside from efficiency, itself an important policy objective, equity, accessibility, and implementation costs associated with the right pricing must be considered. Focusing on the examples of China, Mexico, Morocco, South Africa, and Turkey, Pricing Irrigation Water provides a clear methodology for studying farm-level demand for irrigation water. This book is the first to link the macroeconomics of policies affecting trade to the microeconomics of water demand for irrigation and, in the case of Morocco, to link these forces to the creation of a water user-rights market. This type of market reform, the contributors argue, will result in growing economic benefits to both rural and urban households.

"The authors focus on policy interventions for improving irrigation water allocation decisions by including both macro and micro considerations in a unified analytical computable general equilibrium (CGE) framework. The approach is demonstrated, using the case of Morocco, by analyzing selected policy (top-down and bottom-up) interventions and external shocks that affect the water sector. Both direct and indirect effects of these interventions are identified. The top-down (macro-to-micro) links are of a trade reform type. The bottom-up (micro-to-macro) links pertain to changes in farm water assignments and the possibility of water trading. The authors find that water productivity is strongly influenced by these policies, with the general equilibrium (indirect) effects modifying and sometimes reversing the partial equilibrium (direct) effects. They also find that the impacts of the two reforms assessed are different, with trade reform having an absolute impact of a higher magnitude than the water reform. Finally, the authors show that the sequence of introducing the policy reforms has different consequences. "--World Bank web site.
