Water in a Dry Land is a story of research about water as a source of personal and cultural meaning. The site of this exploration is the iconic river system which forms the networks of natural and human landscapes of the Murray-Darling Basin, Australia. In the current geological era of human induced climate change, the desperate plight of the system of waterways has become an international phenomenon, a symbol of the unsustainable ways we relate to water globally. The Murray-Darling Basin extends west of the Great Dividing Range that separates the densely populated east coast of Australia from the sparsely populated inland. Aboriginal peoples continue to inhabit the waterways of the great artesian basin and pass on their cultural stories and practices of water, albeit in changing forms. A key question informing the book is: What can we learn about water from the oldest continuing culture inhabiting the world's driest continent? In the process of responding to this question a team of Indigenous and non-Indigenous researchers formed to work together in a contact zone of cultural difference within an emergent arts-based ethnography. Photo essays of the artworks and their landscapes offer a visual accompaniment to the text on the Routledge Innovative Ethnography Series website, http://www.innovativeethnographies.net/. This book is perfect for courses in environmental sociology, environmental anthropology, and qualitative methods.

The Ogallala aquifer, a vast underground water reserve extending from South Dakota through Texas, is the product of eons of accumulated glacial melts, ancient Rocky Mountain snowmelts, and rainfall, all percolating slowly through gravel beds hundreds of feet thick. Ogallala: Water for a Dry Land is an environmental history and historical geography that tells the story of human defiance and human commitment within the Ogallala region. It describes the Great Plains' natural resources, the history of settlement and dryland farming, and the remarkable irrigation technologies that have industrialized farming in the region. This newly updated third edition discusses three main issues: long-term drought and its implications, the efforts of several key groundwater management districts to regulate the aquifer, and T. Boone Pickens's failed effort to capture water from the aquifer to supply major Texas urban areas. This edition also describes the fierce independence of Texas ranchers and farmers who reject any governmental or bureaucratic intervention in their use of water, and it updates information about the impact of climate change on the aquifer and agriculture. Read Char Miller's article on theconversation.com to learn more about the Ogallala Aquifer.

In order to provide water security in the twenty-first century, there is universal agreement that a continuation of current policies and extrapolation of trends is not an option. Also clear is that from both water supply and development perspectives, the world's arid and semi-arid regions are those currently and potentially experiencing the highest water stresses. One third of the world's land surface is classified as arid or semi-arid, and about half of all countries are directly affected in some way by problems of aridity. The hydrology of arid and semi-arid areas is also known to be substantially different from that in more humid regions. It is therefore essential that investigation methods appropriate to the former are developed and applied, and that strategies for arid and semi-arid region water resources development recognise the principal characteristics of in-situ hydrological processes.

Dryland degradation and desertification now affect almost a billion people around the world. Tragically, the biological resources and productivity of millions of acres of land are lost to desertification each year because people remain unaware of strategies and techniques that could improve yields, reduce risk, and begin healing the world's deserts. A Guide for Desert and Dryland Restoration is the first book to offer practical, field-tested solutions to this critical problem. Author David Bainbridge has spent more than 25 years actively involved in restoring lands across the American Southwest. A Guide for Desert and Dryland Restoration presents the results of his years of fieldwork, as well as research and experience from scientists and practitioners around the globe. The book discusses the ecology of desert plants, explores the causes of desertification and land abuse, and outlines the processes and procedures needed to evaluate, plan, implement, and monitor desert restoration projects. It sets forth economical and practical field-tested solutions for understanding site characteristics, selecting and growing plants, and ensuring that they survive with a minimal amount of water and care. Each chapter represents a guide to a critical topic for environmental restoration; extensive photographs, diagrams and drawings give detailed information for immediate application, and additional resources are included in appendixes. A Guide for Desert and Dryland Restoration is the first comprehensive book focused on restoring arid regions, and clearly demonstrates that arid lands can be successfully rehabilitated. In addition to restorationists, the book will be an invaluable resource for anyone working in arid lands, including farmers, ranchers, gardeners, landscapers, outdoor recreation professionals, and activists.

Dryland salinity is becoming a growing problem for Australia, as it impacts upon agriculture, water quality, infrastructure and the environment. In the context of developing a national policy for natural resource management, this report contains the outcomes of the review of the current national policy framework on dryland salinity and outlines new strategic directions. This policy framework recognises that dryland salinity should be addressed in an integrated manner with other land, water and vegetation degradation issues. Rather than in isolation, and at the appropriate catchment and regional scale. While this report can provide a broad approach to addressing dryland salinity, it does not suggest that the dryland salinity problem can be entirely solved or that we have all the knowledge required to develop solutions to the problem. The directions outlined in this document are the result of a fruitful collaboration across jurisdictions, acknowledging that governments and industry must work together in partnership with communities to ensure that the future management of dryland salinity achieves significant positive change.

By combining the analysis of biotic and abiotic components of terrestrial ecosystems, this volume provides a synthesis of material on arid and semiarid landscapes, which is currently scattered in a number of books and journal articles. The focus on water-limited ecosystems is motivated by their high sensitivity to daily, seasonal, and decadal perturbations in water availability, and by the ecologic, climatic, and economic significance of most of the world's drylands. Conceived as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. The chapters have been contributed by authors with different expertise, who work in several arid areas around the world. They describe the various interactions among the biological and physical dynamics in dryland ecosystems, starting from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns.

No crop can be grown without being adequately supplied with the requisite amount of water at the proper time. A thorough knowledge of the hydrological cycle, amount and distribution of rainfall, water resources and irrigation projects in India facilitates efficient utilization of water for crop production. Inadequate supply of water to crops in semi-arid and arid regions adversely affects agricultural production. Properties of water, the mode of its entry into the soil and its absorption by roots of crops are important for irrigation. This necessitates accurate determination of the soil moisture content, the plants and available water which is essential for growth and yield of crops. Its deficiency adversely affects their growth and yield. Irrigation must be extended to unirrigated areas in order to increase the production of food, fibre and fodder for which we must know the source of irrigation water, units and methods of measurement of water, methods of irrigating crop fields, factors affecting the choice of irrigation methods, the degree of the suitability of the available water for irrigating crops and the factors affecting the suitability of water for irrigation. As water is a relatively scarce commodity, we must know whether water of a little inferior quality can be utilized to irrigate crops. In addition, we must be familiar with the precautions which need to be taken in this regard. The accumulation of excess water in the soils of the crop fields affects the growth of crops adversely enough to reduce their yields. Choice of the method of land drainage varies with the variation in the topography of the land. It is also necessary to rectify the causes of waterlogging to bring the waterlogged land back under the plough to increase agricultural production. This necessitates drainage investigation and laying out of the proper drainage system. Water requirement of crops depends on the climate and the crop. More water is required to produce crops in the arid region than in the humid region. Crops like paddy and sugar cane require much larger amount of water than finger millet and pearl millet. The book extensively deals with all these aspects related to soil and crop production and suggests measures to enhance productivity through water conservation and proper management of water resources. It will be highly useful for the students, teachers and researchers working in this field. Besides, agriculturists and general readers will also find it useful and informative.

It includes key topics such as vegetation, geomorphology, desertification, micro-habitats, and adaptation to dryland environments. This interdisciplinary volume provides an extensive review of the primary literature (covering nearly 2000 references) and the conventional and satellite datasets that form key research tools for dryland climatology. Illustrated with over 300 author photographs, it presents a unique view of dryland climates for a broad spectrum of researchers, environmental professionals and advanced students in climatology, meteorology, geography, environment science, earth system science, ecology, hydrology and geomorphology.

Dreaming of Dry Land

Not long after the conquest, the City of Mexico's rise to become the crown jewel in the Spanish empire was compromised by the lakes that surrounded it. Their increasing propensity to overflow destroyed wealth and alarmed urban elites, who responded with what would become the most transformative and protracted drainage project in the early modern America—the Desagüe de Huehuetoca. Hundreds of technicians, thousands of indigenous workers, and millions of pesos were marshaled to realize a complex system of canals, tunnels, dams, floodgates, and reservoirs. Vera S. Candiani's Dreaming of Dry Land weaves a narrative that describes what colonization was and looked like on the ground, and how it affected land, water, biota, humans, and the relationship among them, to explain the origins of our built and unbuilt landscapes. Connecting multiple historiographical traditions—history of science and technology, environmental history, social history, and Atlantic history—Candiani proposes that colonization was a class, not an ethnic or nation-based phenomenon, occurring simultaneously on both sides of an Atlantic, where state-building and empire-building were intertwined.

Since water sustains life, effective management of water resources demands a holistic approach, linking social and economic development with protection of natural ecosystems. The effective management links land and water resources across the whole of a catchment area or groundwater aquifer. The Workshop addressed the broader issues of water management in the context of land use and the environment and within the framework of river basin management. More specifically, the Workshop dealt with: defining land and water linkages; developing a conceptual framework to predict land, water and plant nutrient interaction; establishing a landscape and river basin approach to integrated management of natural resources; and drafting a programme of action including applied research and modelling, education, extension and manuals and field projects aimed at promoting integrated management of natural resources. This publication contains the report and recommendations of the Workshop and edited versions of eight papers which were presented and discussed in the Workshop.
