Water Management and Climate Change

Water Management and Climate Change PDF Author: Cecilia Tortajada
Publisher: Routledge
ISBN: 1317611276
Category : Business & Economics
Languages : en
Pages : 187

Book Description
To plan successfully and manage the increased uncertainties posed by likely future climate change, knowledge needs to advance much more for the water profession beyond what it is now available. Meeting these challenges does not depend exclusively on advances in climatological-hydrologic models. Policies for adaptation and strategies for mitigation measures have to be formulated on the basis of what are likely to be the potential impacts. These will have to be regularly fine-tuned and implemented according to changing needs and as more reliable knowledge and data become available. Even more challenging will be the politics of policy making and implementation, which will require a quantum leap from current policy-making and implementation processes. One can even say that, in addition to the development of more reliable models, the politics of climate change and water management remains one of the greatest uncertainties for the water profession. This book addresses water management practices and how these should and could be modified to cope with climatic and other related uncertainties over the next two to three decades; the types of strategies and good practices that may be available or have to be developed to cope with the current and expected uncertainties in relation to climate change; and the types of knowledge, information and technological developments needed to incorporate possible future climate change impacts within the framework of water resources management. Decision making in the water sector under changing climate and related uncertainties, and societal water security under altering and fluctuating climate are also discussed. Several case studies are included from several basins, cities, regions and countries in both developed and non-developing countries. This book was published as a special issue of the International Journal of Water Resources Development.

Water Risk Hotspots for Agriculture

Water Risk Hotspots for Agriculture PDF Author: Organisation for Economic Co-Operation and Development (OECD)
Publisher: IWA Publishing
ISBN: 1780409362
Category : Science
Languages : en
Pages : 198

Book Description
Agriculture is expected to face increasing water risks that will impact production, markets, trade and food security - risks that can be mitigated with targeted policy actions on water hotspots. This report develops the hotspot approach, provides an application at the global scale, and presents a mitigation policy action plan. The People’s Republic of China, India and the United States are identified as countries facing the greatest water risks for agriculture production globally. A global simulation shows that, in the absence of action, water risks in Northeast China, Northwest India and the Southwest United States in particular could have significant production, price and trade consequences. Agriculture water risks could also result in broader socio-economic and food security concerns. Farmers, agro food companies, and governments can all play a role in responding to water risks at hotspot locations. A three-tier policy action plan is proposed to confront water risk hotspots, encompassing targeted responses, adapted national policies, strengthened market integration and international collaboration.

Efecto de la modernización de regadíos sobre la cantidad y la calidad de las aguas PDF Author: Sergio Lecina Brau

Book Description
El gobierno español ha desarrollado dos planes para apoyar la modernización de aproximadamente dos millones de hectáreas de regadío. Sus dos principales objetivos son el incremento de la competitividad de la agricultura de regadío, y el ahorro de 3.000 hm3 anuales de agua. Para estimar este ahorro se ha usado generalmente el concepto de eficiencia del riego. Sin embargo, este concepto no recoge principios hidrológicos básicos como la reutilización del agua y su calidad, la distinción entre uso y consumo, y la localización del uso dentro de la cuenca hidrológica. Este estudio analiza los efectos de la modernización de regadíos sobre la cantidad y la calidad del agua, tomando la cuenca del Ebro como caso de estudio. Para ello se ha realizado una aproximación conceptual basada en la contabilidad del agua. Esta metodología aplica balances para considerar los principios hidrológicos antes indicados. La modernidad no supondrá un ahorro de agua en cuencas donde la mayor parte de los retornos de riego se originen lejos de la costa y sean reutilizables. Por el contrario, la modernización incrementará su consumo y reducirá su disponibilidad, dado el incremento que experimentará la producción agraria. Los agricultores invierten en este proceso para aumentar la productividad de sus explotaciones. Sin embargo, la modernización reducirá la masa de contaminantes exportada desde el regadío. La mejora de la competitividad agraria y de las condiciones de trabajo de los agricultores, así como la mejora global de la calidad del agua, serán los principales beneficios de estos planes para la sociedad.

The North American Mosaic

ISBN:
Category : Agriculture
Languages : en
Pages : 240

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Water, Agriculture and the Environment in Spain: can we square the circle? PDF Author: Lucia De Stefano
Publisher: CRC Press
ISBN: 0415631521
Category : Science
Languages : en
Pages : 340

Book Description
"The world water problems are a due to bad governance, not to physical water scarcity." This book is inspired by this statement and explores whether it holds in a specific country, Spain, where climatic conditions – Spain is one of the most arid countries of the European Union - would fully justify saying that water problems are due to physical water scarcity. The metrification of water uses and their monetary value is a first important step in understanding how reallocation of water among users could help mitigating many of current water problems in Spain. However, water reallocation among users or from users to nature is far from simple. Initiatives portrayed as the solution to the water governance ‘jigsaw’ – e.g. water trade, improved water use efficiency, users collective action, public participation – are not free of difficulties and shortcomings. The book explores the growing need for maintaining Spain’s natural capital and the human component of water governance – people’s needs, wishes, (vested) interests, aspirations – that often determine the result of decisions and, sometimes, lead water management to a deadlock. This book takes a step forward in showing a more complex - and also closer to reality - picture of water governance in Spain.

Publisher: CRC Press
ISBN: 1138001430
Category : Law
Languages : en
Pages : 324

Book Description
Integrated water resources management advocates a coordinated approach for managing water resources in a way that balances social and economic needs with concern for the environment. While potentially useful, integrated water management is also controversial. Supporters believe that the multi-dimensional nature of water can only be understood and managed from a holistic perspective, while critics often argue that integrated water management lacks suffi ciently well-defi ned rules for its practical implementation. This book, written by academics, users and practitioners, provides a down-to-earth approach to the ideal of integrated water resources management, drawing from conceptual frameworks and real-life practice to identify the key aspects that are yet to be resolved. As such, it examines the role of water accounting, food trade, environmental externalities and intangible values as key aspects whose consideration may help the water management community move forward. Overall, integrated water resources management is perceived to be a useful utopia, whose value lies more in the steps that need to be taken to make it a reality than in achieving its ever-elusive end goal.
