Water for the People features twenty-five essays by world-renowned acequia scholars and community members that highlight acequia culture, use, and history in New Mexico, northern Mexico, Chile, Peru, Argentina, Spain, the Middle East, Nepal, and the Philippines, situating New Mexico's acequia heritage and its inherent sustainable design within a global framework. The lush landscapes of the upper Rio Grande watershed created by acequias dating from as far back as the late sixteenth century continue to irrigate their communities today despite threats of prolonged drought, urbanization, private water markets, extreme water scarcity, and climate change. Water for the People celebrates acequia practices and traditions worldwide and shows how these ancient irrigation systems continue to provide arid regions with a model for water governance, sustainable food systems, and community traditions that reaffirm a deep cultural and spiritual relationship with the land year after year.

With a roster of international contributors, this volume offers an abundance of solutions to address agricultural water management challenges in today's water-scarce areas of the world. The authors present studies on farmer-friendly irrigation scheduling methods, model-based analysis of crop water requirements, ways to optimize surface irrigation systems, and hydraulic design and management of surface water systems. The book goes on to highlight ways to improve soil properties by taking into account spatial, temporal, and spectral variability in soil properties. The volume also covers various innovative research studies on soil and water productivity of vegetable cultivation under water-stressed areas, application of coir geotextiles, and the role of biofertilizers in controlling soil degradation and maintaining fertile topsoil. Crop management strategies to enhance the efficient use of marginal and saline lands for nonconventional crops are also discussed. The book is divided into four sections, covering: engineering interventions in irrigation management technological interventions in management of soil properties technological inventions for soil and water conservation crop management for non-conventional use This volume will serve as an invaluable resource for academicians, researchers, engineers, agronomists, extension officers, students, and farmers in the broad discipline of agricultural and biological engineering.

"All three volumes of Achieving sustainable production of milk should be considered as a whole...Over more than 1200 pages, the authors review all fields of milk production, beginning with milk composition, genetics and breeding, safety and milk quality, sustainability of milk production as well as dairy herd management, health, welfare and nutrition of dairy. All three volumes could be considered a standard reference for graduate students in the fields of dairy science and veterinary medicine, animal and dairy scientists at universities and other research centres, and also those in governments and companies involved or working in the field of milk production." Animal Feed Science and Technology In meeting rising demand, more intensive dairying systems face a range of challenges such as maintaining high standards of safety in the face of the continuing threat from zoonoses entering the food chain, whilst sustaining nutritional and sensory quality. At the same time farms need to become more efficient and sustainable. Finally, farming must also meet higher standards of animal health and welfare. Drawing on an international range of expertise, this book reviews research addressing the welfare, nutrition and health of dairy cattle. Part 1 begins by discussing key issues in welfare followed by topics such as genetic selection and welfare, housing and transportation. Part 2 looks at nutrition with chapters on rumen microbiology, feed evaluation and formulation, feed supplements and feed safety. The final part of the book covers aspects of health such as control of diseases and other disorders such as lameness as well as dairy herd health management. Achieving sustainable production of milk Volume 3: Dairy herd management and welfare will be a standard reference for animal and dairy scientists in universities, government and other research centres and companies involved in beef production. It is accompanied by two other volumes which review milk composition, genetics and breeding as well as safety, quality and sustainability.

In most developing countries wastewater treatment systems are hardly functioning or have a very low coverage, resulting in large scale water pollution and the use of very poor quality water for crop irrigation especially in the vicinity of urban centres. This can create significant risks to public health, particularly where crops are eaten raw. Wastewater Irrigation and Health approaches this serious problem from a practical and realistic perspective, addressing the issues of health risk assessment and reduction in developing country settings. The book therefore complements other books on the topic of wastewater which focus on high-end treatment options and the use of treated wastewater. This book moves the debate forward by covering also the common reality of untreated wastewater, greywater and excreta use. It presents the state-of-the-art on quantitative risk assessment and low-cost options for health risk reduction, from treatment to on-farm and off-farm measures, in support of the multiple barrier approach of the 2006 guidelines for safe wastewater irrigation published by the World Health Organization. The 38 authors and co-authors are international key experts in the field of wastewater irrigation representing a mix of agronomists, engineers, social scientists and public health experts from Africa, Asia, Europe, North America and Australia. The chapters highlight experiences across the developing world with reference to various case studies from sub-Saharan Africa, Asia, Mexico and the Middle East. The book also addresses options for resource recovery and wastewater governance, thus clearly establishes a connection between agriculture, health and sanitation, which is often the missing link in the current discussion on 'making wastewater an asset'.

Metal Fabrication Technology for Agriculture presents readers with a fast-paced, yet easy-to-understand introduction to must-know welding processes and techniques. Focusing squarely on agricultural welding applications, each section of this full-color book begins by introducing readers to the equipment and materials to be used in the process. Complete instructions for setup in preparation for welding are also included. Remaining chapters in the section allow readers to concentrate on mastering individual welding techniques in various applications and positions. Extensive coverage of brazing and specialized nonmetallic fabrication is designed to lead readers step-by-step in developing the skills necessary for welding all types of agricultural machinery. Up close shots of actual welds and proven-effective learning aids have also been built into every chapter, making this how-to and reference manual a key resource for today's farmers, ranchers, and students participating in agriculture education programs throughout the country.

This publication provides guidance for water users and districts in selecting, managing, inspecting, and maintaining their water measurement devices. Describes the standard methods and devices used to measure irrigation water. Acquaints irrigation system operators with other established but less common methods and with new or special techniques.

Contains the engineering tools and concepts that have proven useful in planning, constructing, and maintaining drainage systems for successful long term irrigation projects. Provides a ready reference and guide for making accurate estimates of drainage requirements.

This trusted text provides a thorough introduction to agricultural mechanics, covering fundamental mechanical and engineering theory, common tools and materials, and a wide range of practical applications. Units explore essential topics such as career opportunities, shop orientation and procedures, woodworking and metal working, tool fitting, project planning, cutting and welding, paints and paint application, power mechanics, electrical wiring, plumbing, hydraulics, concrete and masonry, and agricultural structures.Safety is also emphasized strongly throughout the text, both within each chapter and in a dedicated unit. To engage today's students and make even complicated principles easier to apply, the text features abundant, full-color images, illustrations, charts, and data tables, as well as detailed drawings of over 50 complete project plans.
