Book Description
The availability of adequate freshwater has become a limiting factor of the quality of life, worldwide. More than availability, the problem is often the rational use of water than ensure its continuality. In the semi-arid and arid regions water scarcity was always a dominant problem moreover, the interference with the natural hydrologic cycle as a result of overexploitation of both surface and ground waters and of changes in land usage resulted not only in the reduction of the available water amounts but also in the deterioration of the water quality due to pollution from urban, industrial and agricultural practices and salinity build-up in soil and water. Such a situation is in all cases a pretext for discord and assignment of blame on those supposedly responsible for the deterioration of the water accessibility , especially in view of the possible high cost and technical complexity of the measures that need to be taken for remedying and alleviating the situation.Water Scarcity and Sustainable Agriculture in Semiarid Environment presents insight into the multifaceted relationship between water scarcity and climate change, agricultural water-use effectiveness, and crop-water stress management as for sustainable crop production these cause- and effect relationships and classifying the most apposite responses are vital.Ample evidence exists that improved on-farm water management can close water-related yield gaps to a considerable degree, but its global significance remains unclear. In this book, we investigate systematically to what extent integrated crop water management might contribute to closing the global food gap, constrained by the assumption that pressure on water resources and land does not increase. This book serves as a helpful guide to students, practitioners, researchers, policy makers, and research institutions in agricultural water management, irrigation and drainage, crop physiology, and sustainable agriculture.

Book Description
Water Scarcity and Sustainable Agriculture in Semiarid Environment: Tools, Strategies and Challenges for Woody Crops explores the complex relationship between water scarcity and climate change, agricultural water-use efficiency, crop-water stress management and modeling water scarcity in woody crops. Understanding these cause- and effect relationships and identifying the most appropriate responses are critical for sustainable crop production. The book focuses on Mediterranean environments to explain how to determine the most appropriate strategy and implement an effective plan; however, core concepts are translational to other regions. Informative for those working in agricultural water management, irrigation and drainage, crop physiology and sustainable agriculture. Focuses on semi-arid crops including olive, vine, citrus, almonds, peach, nectarine, plum, subtropical fruits and others Explores crop physiological responses to drought at plant, cellular and/or molecular levels Presents tool options for assessing crop-water status and irrigation scheduling

Book Description
International voices fill the pages of Water and Sustainability in Arid Regions, forming an original scientific exploration of current water research and management issues. In arid regions, agriculture that is ill-adapted to the environment, accelerated urbanization, poverty, and increasing pollution challenge access to and uses of water. Understanding these issues requires incorporating findings from both the physical and social sciences at different temporal and spatial scales. The chapters in this book were written by hydrologists, remote sensing specialists, ecologists, historians, economists, political scientists, architects, archaeologists, and other experts who live in and study arid lands. The authors present updates, overviews, and analyses of water challenges these areas have faced and are striving to address, from salinization in the fabled Taklimakan Desert in China to land degradation in the northern Mediterranean to groundwater over-exploitation in the southwestern United States. The book also examines desertification, remote sensing, qanat systems, architecture, arsenic contamination, and other case studies from Iran, the Maghreb region, Argentina and Chile, and Mexico. From this conceptual mosaic of comparative perspectives and research methods emerges a strong assumption: an interdisciplinary approach that combines physical and social sciences is the first step toward globally and comprehensively addressing water and sustainability."This book is a valuable and welcome contribution to the discussion of water and sustainable development. Through the collection of chapters, the book clearly illustrates the contemporary diversity of approaches to water scarcity and presents pertinent and new research findings that readers generally do not find compiled together. The result is a highly relevant, accessible, and timely resource that is unique in its international and interdisciplinary content. This is a must-read for anyone working on environmental and sustainability issues in arid lands."André Mariotti, University Pierre et Marie Curie, and INSU - CNRS (National Institute for Earth Sciences and Astronomy-National Center for Scientific Research/Centre National de la Recherche Scientifique), France "Anyone who reads this book will find himself or herself contemplating the need to rethink how we approach the issue of water and sustainability in arid lands. Drawing on the expertise of both physical and social scientists, the chapters taken as a whole present global, historic, and current perspectives on water scarcity in a multi-layered way that rarely has been done before."

Book Description
India is a fast developing economy whose natural resource base, comprising land and water supporting agricultural production, are not only under enormous stress, but also complex and not amenable to a uniform strategy. This book addresses strategies for food security and sustainable agriculture in India, including lessons to be learned in other developing economies across the world.

Book Description
The report aims to provide a conceptual framework to address food security under conditions of water scarcity in agriculture. It has been prepared by a team of FAO staff and consultants in the framework of the project "Coping with water scarcity - the role of agriculture", and has been discussed at an Expert Consultation meeting organized in FAO, Rome, during the period 14-16 December 2009 on the same subject. It was subsequently edited and revised, taking account of discussions in the Expert Consultation and materials presented to the meeting. The purpose of the Expert Consultation was to assist FAO to better design its water scarcity programme. In particular, the experts were requested to provide recommendations on the range of technical and policy options and associated principles that FAO should promote as part of an agricultural response to water scarcity in member countries. The document offers views on the conceptual framework on which FAO's water scarcity programme should be based, proposes a set of definitions associated with the concept of water scarcity, and indicates the main principles on which FAO should base its action in support to its member countries. At the meeting, experts were requested to review the draft document and provide feedback and recommendations for its finalization. Issues that were addressed in discussions included: 3⁄4 Water scarcity: agreement on key definitions. 3⁄4 The conceptualisation of water scarcity in ways that are meaningful for policy development and decision-making. 3⁄4 The quantification of water scarcity. . 3⁄4 Policy and technical response options available to ensure food security in conditions of water scarcity. . 3⁄4 Criteria and principles that should be used to establish priorities for action in response to water scarcity in agriculture and ensure effective and efficient water scarcity coping strategies.
