Water Scarcity and Sustainable Agriculture in Semiarid Environment by Anonim Pdf

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.

Compendium of community and indigenous strategies for climate change adaptation by Mwenge Kahinda, J., Bahal’okwibale, P. M., Budaza, N., Mavundla, S., Nohayi, N.N., Nortje, K., Boroto, R.J. Pdf

Climate change is a major challenge for life on Earth. It is mainly manifested through modifications of average temperature, rainfall intensity and patterns, winds and solar radiation. These modifications significantly affect basic resources, such as land and water resources. Populations at disproportionately higher risk of adverse consequences with global warming of 1.5°C and beyond include disadvantaged and vulnerable populations, some indigenous peoples, and local communities dependent on agricultural or coastal livelihoods (IPCC, 2018). Therefore, adaptation measures are recommended in order to cope with climate change. Indigenous peoples have developed practices for climate change adaptation, based on their long-term experience with adverse climatic effects. There was thus a need to identify such practices as they could be effectively mainstreamed in community-based adaptation programmes. This report makes an inventory of indigenous and community adaptation practices across the world. The inventory was mainly done through literature review, field work and meetings with selected organisations. The case studies documented are categorized in five technologies and practices themes, including: (1) Weather forecasting and early warning systems; (2) Grazing and Livestock management; (3) Soil and Water Management (including cross slope barriers); (4) Water harvesting (and storage practices); (5) Forest Management (as a coping strategy to water scarcity), and; (6) Integrated wetlands and fisheries management. These were then related to the corresponding main agro-ecological zones (AEZ), namely arid, semi-arid, sub-humid, humid, highlands and coastal and wetlands. The AEZ approach was considered as an entry-point to adopting or adapting an existing indigenous strategy to similar areas. Challenges that threaten the effectiveness of indigenous and community adaption strategies were identified. These challenges include climate change itself (which is affecting the indicators and resources used by communities), human and livestock population growth (which is increasing pressure on natural resources beyond their resilience thresholds), current institutional and political settings (which limit migrants’ movements and delimits pieces of usable land per household), cultural considerations of communities (such as taboos and spiritual beliefs), and the lack of knowledge transfer to younger communities. Indigenous knowledge provides a crucial foundation for community-based adaptation strategies that sustain the resilience of social-ecological systems at the interconnected local, regional and global scales. In spite of challenges and knowledge gaps, these strategies have the potential of being strengthened through the adoption and adaptation of introduced technology from other communities or modern science. Attention to these strategies is already being paid by several donor-funded organisations, although in an uncoordinated manner.

Water and Sustainability in Arid Regions by Graciela Schneier-Madanes,Marie-Francoise Courel Pdf

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."

Coping with Water Scarcity by Jean-Marc Faurès Pdf

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.

Water Scarcity, Livelihoods and Food Security by Larry W. Harrington,Myles J. Fisher Pdf

This volume reviews the evolution of ten years’ learning and discovery about water scarcity, livelihoods, and food security within the CGIAR Challenge Program on Water and Food. It draws on the experiences of over 100 projects conducted in ten river basins in the developing world. The book describes how the program’s design evolved from an emphasis on water scarcity, water productivity, and water access to an emphasis on using water innovations to improve livelihoods and address development challenges in specific river basins. It shows how the research was used to foster change in stakeholder behavior, linking it to improved knowledge, attitudes, and skills, which were fostered by stakeholder participation, innovation, dialogue, and negotiation. The authors describe development challenges, their drivers and their political context, how to address them through technical, institutional, and policy innovations; and the consequences of change at different scales, time frames on equity, resilience, and ecosystem services. Overall, the work represents a major synthesis and landmark publication for all concerned with water resource management and sustainable development.

Virtual Water by Chittaranjan Ray,David McInnes,Matthew Sanderson Pdf

Virtual Water explores the role of "virtual water" – the water embedded in a product – in ongoing conversations of agriculture, trade and sustainability in an increasingly inter-connected world. A pervasive theme throughout the book is the general lack of knowledge of the use of water in producing and consuming food. The chapters, arising from a workshop supported by the OECD Co-operative Research Programme: Biological Resources Management for Sustainable Agricultural Systems, on virtual water, agriculture and trade at the University of Nebraska-Lincoln, consider questions of gaps in knowledge, why sustainability matters and the policy implications of virtual water trade. Contributors show how water is a lens through which to examine an array of vital issues facing humanity and the planet: human and animal health; food production; environmental management; resource consumption; climate change adaptation and mitigation; economic development, trade and competitiveness; and ethics and consumer trust. Virtual Water will be of great interest to scholars of water, resource management and consumption, the environmental aspects of development, agriculture and food production. It originally published as a special issue of Water International.
