1.1 General Framework In most arid and semi-arid countries, water resource management is an issue that is both important and controversial. Most water resources experts now acknowledge that water conflicts are not caused by physical scarcity but are mainly due to poor water management (Rosegrant et al. 2002; Benoit and Comeau 2005; Comprehensive Assessment of Water Management in Agriculture 2007; Garrido and Dinar 2010, among others). The scientific and technological advances of the past 50 years have led to new ways to solve many water-related conflicts, often with tools that seemed unthinkable a few decades ago (Llamas 2005; Lopez-Gunn and Llamas 2008). This study deals with the estimation and analysis of Spain's water footprint, both from a hydrological and economic perspective. Its ultimate objective is to report on the allocative efficiency of water and economic resources. This analysis can provide a transparent and multidisciplinary framework for informing and optimising water policy decisions, contributing at the same time to the implementation of the EU Water Framework Directive (WFD) (2000/60/EC). It also responds to the current mandate of the Spanish Ministry of Environment and Rural and Marine Affairs, which recently issued instructions for drafting river basin management plans in compliance with the EU Water Framework Directive, with a deadline of end of year 2009 and then every 6 years (BOE 2008).

Though the modern Spanish State was formed in the mid Fifteenth Century, historical records show that water works, statues, and the utilization of water dates back to centuries BC. As a semi-arid country, the effort to control, store and assure water supplies to cities and fields is present in numerous historical and political landmarks.

Water policy in Spain has been the focus of Spanish-speaking scholars for decades, yet a comprehensive treatment of the subject has never before been published in English. Water Policy in Spain fills this gap by providing readers with a comprehensive, detailed account of the history of water policy in Spain from the beginnings of the 20th century to the present day.

Part one presents a synopsis of the physical, economic, environmental and climatic bases of Spain, also covering corresponding political topics. Part two reviews the major constraints and opportunities that are relevant to face major water policy challenges. And part three is an in-depth account of water policy in the country.

The issues closely examined include the way in which old water laws and institutions have been able to adapt to new sentimental and institutional challenges, including the significant change in the last decade to comply with the European Union 's Water Framework Directive (WFD). Like many semi-arid countries, climate change, drought risks and water pollution are cause for growing concerns in Spain and the country is still struggling to define a consistent and widely accepted set of policies to combat these threats. Spain 's current water policy is unique because it entails a complete tour de force with respect to what the country has been doing on water matters for centuries. As the WFD must be enforced in 27 States (representing 500 million Europeans), the lessons that can be learnt from the Spanish experience should catch the attention of water practitioners around the world.

The chapters in this volume are peer reviewed editions of the papers presented at the 7th meeting of the Rosenberg International Forum on Water Policy which was held in Buenos Aires, Argentina on November 15-17, 2010. The theme for Forum VII was Water for the Americas: Challenges and Opportunities. This Forum was unique in examining the water problems of the Americas and identifying water management experience gleaned in other parts of the world that might be useful in addressing the problems of the Americas. The sessions illustrated how the water problems of the Americas are common problems, differing only in degree from basin to basin. There was unanimity among the participants about the need for all inhabitants of the Americas to work together to ensure that everyone has access to adequate quantities of healthy water supplies and to appropriate sanitation services. This volume's approach is to identify different responses and policies that address common issues and learn from contrasts and experiences. The value and potential that this approach affords is that it provides critical judgments about what has worked well and what needs to be done to gain a better future for the Americas' water resources and society. Some issues covered in the volume are so pressing and urgent, chief among them is serving the unserved, that any delays putting out new facilities in many a rural areas of Central America may cost lives and reduce the outlook for children. Additionally, the volume makes clear that the outlook for the poorest and the future of hundreds of growing cities are threatened by climate change. This book looks into the future by analyzing present and relevant data and gains insight from the different developmental stages of the hemisphere.

Global change possesses serious challenges for water managers and scientists. In mountain areas, where water supplies for half of the world population originate, climate and hydrologic models are still subject to considerable uncertainty. And yet, critical decisions have to be taken to ensure adequate and safe water supplies to billions of people, millions of farmers and industries, without further deteriorating rivers and water bodies. While global warming is known to cause glaciers retreat and reduced snow packs around the world, it is not clear that mountain discharge will be lower. What is widely recognised is that water management must be adapted to accommodate significant regime changes. However, this inevitably involves managing transboundary rivers, adding further complexity to putting principles in practice.

This book takes global warming and the importance of mountain areas in world water resources as the starting point. First, it provides detailed reviews of the processes going on in several rivers systems and world regions in Europe (Rh ne and Ebro), North America (Canadian Rockies, Western US and Mexico), the Middle East (Jordan), Africa (Tunisia, Kenya and South Africa). These contexts provide case studies and examples that show the difficulties and potential for adaptation to global change. Land-use, economics, numerous modeling approaches are some of the cross-cutting issues covered in the chapters. The volume also includes the views of water practitioners, with two chapters authored by members of the US-Canada International Joint Commission, an industrialist from Western Canada and an environmental leader in Spain.

By combining a rich set of contexts and approaches, the volume succeeds in offering a view of the global challenges faced by water agencies, international donors and researchers around the world. A case is made in some chapters to seek adaptive strategies rather than trying to reduce or control resources variability. This requires factoring in land-use, social and economic aspects, especially in developing countries. Another conclusion is that complex problems can and must be posed and negotiated with the help of models, mapping techniques and science-based facts. However complex these may be, there are ways to translate them to easily interpretable and visualisations of alternative scenarios and courses of action. This book provides numerous examples of the potential of such approaches to draft environmental programmes solve transboundary disputes and reduce the economic consequences of droughts and climate instability.

This book addresses groundwater governance, a subject internationally recognized as crucial and topical for enhancing and safeguarding the benefits of groundwater and groundwater-dependent ecosystems to humanity, while ensuring water and food security under global change. The multiple and complex dimensions of groundwater governance are captured in 28 chapters, written by a team of leading experts from different parts of the world and with a variety of relevant professional backgrounds. The book aims to describe the state-of-the-art and latest developments regarding each of the themes addressed, paying attention to the wide variation of conditions observed around the globe. The book consists of four parts. The first part sets the stage by defining groundwater governance, exploring its emergence and evolution, framing it through a socio-ecological lens and describing groundwater policy and planning approaches. The second part discusses selected key aspects of groundwater governance. The third part zooms in on the increasingly important linkages between groundwater and other resources or sectors, and between local groundwater systems and phenomena or actions at the international or even global level. The fourth part, finally, presents a number of interesting case studies that illustrate contemporary practice in groundwater governance. In one volume, this highly accessible text not only familiarizes water professionals, decision-makers and local stakeholders with groundwater governance, but also provides them with ideas and inspiration for improving groundwater governance in their own environment.

This volume provides an analytical and facts-based overview on the progress achieved in water security in Latin America and the Caribbean (LAC) region over during the last decade, and its links to regional development, food security and human well-being. Although the book takes a regional approach, covering a vast of data pertaining to most of the LAC region, some chapters focus on seven countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico and Peru). A full understanding of LAC's trends progress requires framing this region in the global context: an ever more globalized world where LAC has an increasing geopolitical power and a growing presence in international food markets. The book's specific objectives are: (1) exploring the improvements and links between water and food security in LAC countries; (2) assessing the role of the socio-economic 'megatrends' in LAC, identifying feedback processes between the region's observed pattern of changes regarding key biophysical, economic and social variables linked to water and food security; and (3) reviewing the critical changes that are taking place in the institutional and governance water spheres, including the role of civil society, which may represent a promising means to advancing towards the goal of improving water security in LAC. The resulting picture shows a region where recent socioeconomic development has led to important advances in the domains of food and water security. Economic growth in LAC and its increasingly important role in international trade are intense in terms of use of natural resources such as land, water and energy. This poses new and important challenges for sustainable development. The reinforcement of national and global governance schemes and their alignment on the improvement of human well-being is and will remain an inescapable prerequisite to the achievement of long-lasting security. Supporting this bold idea with facts and science-based conclusions is the ultimate goal of the book.

There is not enough water globally for all the things humans need and want water to do for us. Water supply bubbles are bursting in China, the Middle East and India with potentially serious implications for the global economy and for political stability. Even the United States is depleting groundwater on average 25% faster than it is being replenished. Our thirst for water grows with our population, but the amount of fresh water available on Earth is fixed. If we assume "business as usual" by 2050 about 40% of the projected global population of 9.4 billion is expected to be facing water stress or scarcity. With increasing climate variability being predicted by global climate models, we are likely also to have more people without adequate water more of the time, even in water-rich regions.

Irrigation productivity rose dramatically over the past 40 years as a result of the Green Revolution. However, even if we disregard the environmental impacts caused by that revolution, we are no nearer to achieving global food security than we were 40 years ago, as every time we come close to filling the food production gap population growth and ecosystem decline associated with water diversions to human purposes set us back. Our natural and agricultural ecosystems are trying to tell us something.

This book pursues these overarching themes connecting to water and food production at global and regional scales. The collection offers a comprehensive discussion of all relevant issues, and offers a wide-ranging discussion with the aim of contributing to the global debate about water and food crises.

What exactly is resilience and how can it be enhanced? Farming systems in Europe are rapidly evolving while at the same time being under threat, as seen by the disappearance of dozens of farms every day. Farming systems must become more resilient in response to growing economic, environmental, institutional, and social challenges facing Europe's agriculture. Since the COVID-19 pandemic, the need for enhanced resilience has become even more apparent and continues to be an overarching guiding principle of EU policy making. Resilience challenges and strategies are framed within four main processes affecting decision making in agriculture: risk management, farm demographics, governance and agricultural practices. This empirical focus looks at very diverse contexts, with eleven case studies from Belgium, Bulgaria, France, Germany, Great Britain, Italy, Netherlands, Poland, Romania, Spain and Sweden. This study will help determine the future and sustainability of European farming systems. This title is available as Open Access on Cambridge Core.

Since the financial and food price crises of 2007, market instability has been a topic of major concern to agricultural economists and policy professionals. This volume provides an overview of the key issues surrounding food prices volatility, focusing primarily on drivers, long-term implications of volatility and its impacts on food chains and consumers. The book explores which factors and drivers are volatility-increasing and which others are price level-increasing, and whether these two distinctive effects can be identified and measured. It considers the extent to which increasing instability affects agents in the value chain, as well as the actual impacts on the most vulnerable households in the EU and in selected developing countries. It also analyses which policies are more effective to avert and mitigate the effects of instability. Developed from the work of the European-based ULYSSES project, the book synthesises the most recent literature on the topic and presents the views of practitioners, businesses, NGOs and farmers' organizations. It draws policy responses and recommendations for policy makers at both European and on international levels.

This book provides an overview, by leading world experts, on key issues in global water and food security. The book is divided in a series of over-arching themes and sections. The first part of the book provides an overview of water and food security. The second and third sections look at global trade and virtual water trade, and provide some specific examples on the application of the water footprint at different scales. The fourth section sets the context into wider debates related to global sustainable production and consumption. The last section of the book addresses the role of the silent groundwater revolution to help address water and food security; the water/energy nexus, and the potential for generating new water.
