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
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.
This book highlights the diverse nature of the scientific domains associated with landscape architecture. It emphasises the need to acknowledge that the contribution of each research domain is equally important, offering complementary development opportunities while enabling landscapes to fulfill their multiple functions and ecosystem services in an integrated way, underlining the relevance of theory, methods, and practice to promote sustainable landscape planning and design.
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.
This Book includes selected papers that has been published in the Water journal Special Issue (SI) on Water Supply and Water Scarcity. Moreover, an overview of the SI is included. The papers selected for publication in the SI include review and research papers on water history, on water management issues under water scarcity regimes, on rainwater harvesting, on water quality and degradation, and on climatic variability impacts on water resources. Overall, the issue identify and highlight the main challenges in water sector, and particularly in management and protection of water resources and in use of alternative (non-conventional) water resources, especially in areas with demographic change and climate vulnerability in order to achieve sustainable and secure water supply. Furthermore, general guidelines and possible solutions for an improved and sophisticated water management system are proposed and discussed, such as the adoption of advanced technological solutions and practices that improve water-use efficiency and the use of alternative water resources, to address the growing environmental and health issues and to reduce the emerging conflicts among water users.
Water deficiency in many arid and semi-arid regions in Southern Europe is becoming a major constraint for economic welfare and sustainable regional development. These regions are characterised by high spatial and temporal imbalances of water demand and supply, seasonal water uses, inadequate water resources and poor institutional water management. The aim of this book is to formulate appropriate strategies and guidelines for water management necessary for the formulation and implementation of integrated sustainable management of water resources. Lessons are learned from various case studies, which examine competing water use patterns, compare governance structures and how these have evolved in response to scarcity, and structural and non-structural instruments to address water deficiency. Water Management in Arid and Semi-Arid Regions will appeal to policymakers in relevant countries as well as to scholars and researchers of environmental studies and economics.
Offering a cross-country examination and comparison of drought awareness and experience, this book shows how scientists, water managers, and policy makers approach drought and water scarcity in arid and semi-arid regions of Spain, Mexico, Australia, South Africa and the United States.

In December 2002, a group of specialists on water resources from the United States and Iran met in Tunis, Tunisia, for an interacademy workshop on water resources management, conservation, and recycling. This was the fourth interacademy workshop on a variety of topics held in 2002, the first year of such workshops. Tunis was selected as the location for the workshop because the Tunisian experience in addressing water conservation issues was of interest to the participants from both the United States and Iran. This report includes the agenda for the workshop, all of the papers that were presented, and the list of site visits.
The rural poor, who are the most vulnerable, are likely to be disproportionately affected.
