As human populations expand and demands upon natural resources increase, the need to manage the environments in which people live becomes more important but also more difficult. Land and water management is especially critical as the use of upstream watersheds can drastically affect large numbers of people living in downstream watersheds. An integrated approach that stresses both the importance of participatory planning and the institutional and technical constraints and opportunities is therefore necessary. The institutional and technical context for managing watersheds and river basins, including the involvement of both the public and private sectors, is also examined.

R726 Discovery Miles 7 260 Ships in 10 - 15 working days

The author of this book has traveled extensively in many desert and semi-desert territories of the U.S.S.R., Morocco, Tunisia, the Egyptian region of the U.A.R., Pakistan and India where he realized the importance of water for the reclamation of vast areas of arid and semi-arid lands. During his visits the author became acquainted with the theory and practice of land irrigation in many countries of North Africa and Asia. The present book is the first attempt at generalizing the vast amount of material dealing with the hydrogeology of the irrigated lands of the arid zone of North Africa and Asia, stretching from the African coastline of the Atlantic Ocean to the central parts of Asia. Outlined in this book are the origin and distribution of saline lands in the deserts of North Africa, the Arabian Peninsula, the Iran Highlands, Middle Asia, China and Mongolia. A description is given of the surface waters in irrigated areas of the arid zone together with the sources, movement and draining, infiltration, condensation and evaporation of water in the desert and semi-desert territories. The book gives a sketch of the regime of free ground waters in irrigated areas and methods of studying it, problems of water balance and its forecasting, based on experimental research and simple theoretical calculations. Principles of the hydrogeological division of irrigated lands into districts and basic measures to prevent their salinization are also given. The book can serve as a textbook for engineer-hydrogeologists, melioration specialists and students at specialized hydrogeological and agricultural institutes and schools.

We must enhance the effectiveness ofland stewardship and management of the world's natural resources to meet a growing global population's need for conservation, sustainable development, and use of land, water, and other natural resources. Ecosystem-based, mul tiple-use land stewardship is necessary when considering the present and future uses ofland, water, and other natural resources on an operationally efficient scale. We need holistically planned and carefully implemented watershed management practices, projects, and pro grams to accommodate the increasing demand for commodities and amenities, clear water, open space, and uncluttered landscapes. An international conference in Tucson, Arizona, from March 13 to 16, 2000, examined these needs and increased people's awareness of the contributions that ecosystem-based, multiple-use watershed management can make to future land stewardship. The conference was sponsored by the School of Renewable Natural Resources, University of Arizona; the College of Agriculture, University of Arizona; the Rocky Mountain Research Station, USDA Forest Service; the Research Center for Conservation of Water Resources and Disaster Pre vention, National Chung-Hsing University, Taiwan; the Department of Forest Resources, University of Minnesota; the Center for Integrated Natural Resources and Agriculture Man agement, University of Minnesota; the Centro de Investigaciones Biologicas del Noreste, Mexico; the International Arid Lands Consortium; the USDA Natural Resources Conserva tion Service; the Bureau of Land Management of the Department of the Interior; the Salt River Project, Phoenix, Arizona; the Southern Arizona Chapter, Southwestern Section of the Society of American Foresters; and IUFRO Working Party 8. 04. 04, Erosion Control by Watershed Management."

Sprinkle and Trickle Irrigation (Hardcover, Annotated edition): Jack Keller, Ron D. Bliesner Sprinkle and Trickle Irrigation (Hardcover, Annotated edition)

R2,276 Discovery Miles 22 760 Ships in 10 - 15 working days

This book, first published in 1990 and reprinted here, is a comprehensive, state-of-the art reference on the design principles and management techniques of two primary agricultural irrigation methods. The book presents a systematic approach to the optimal design, management and operation of these two systems. Focusing on the synthesis of the entire design process, the authors present the chapters in the sequence used to design systems with the analytical material presented and demonstrated in a concise manner. For the first time in any book, Sprinkle and Trickle Irrigation offers complete design strategies and presentations for all of the major types of sprinkle and trickle systems: - Periodic-move - Center-pivot - Traveling sprinkler - Linear-moving - Set sprinkler - Drip, spray and line-source Sequential sample calculations that involve the steps in the design of typical irrigation systems are used extensively. As the book progresses, these calculations become more comprehensive and are linked together to form complete design packages for the various types of pressurized systems. The book also presents a section on selecting pressurized irrigation systems, a review of soil-plant-water relationships, unique insight into pipeline hydraulics and economics, design specifications for fertilization and frost control, a glossary and an annotated bibliography of ASAE Standards for Pressurized Irrigation Systems. Sprinkle and Trickle Irrigation is an important practical reference for agricultural engineers, irrigation system designers and agricultural managers, as well as a vital text for professors and researchers in agricultural engineering. "Sprinkle and Trickle Irrigation presents beginning-to-end coverage of the processes and computations needed in the planning and design of sprinkle and trickle irrigation systems. The textbook is created for the thinking person who desires more than cookie-cutter recipes or simple, routine "rule-of-thumb" designs. Rather, the authors of Sprinkle and Trickle Irrigation present concise rationale and philosophy behind each computation formula, figure and table. They decouple "recommended" design parameters into underlying components that can be recoupled at the time of the design to apply to specific cases and situations. In the process, the reader gains visualization skills that allow him/her to peer "inside" an irrigation system, both hydraulically, economically, and operationally. Sprinkle and Trickle Irrigation is a classic design text and reference that should be on every practitioner's desk. The chapters on center-pivot, linear-move and travelling sprinklers go well beyond other current texts. Solid and encompassing economics are infused into all design topics, including application, distribution, and pumping systems. I have lectured out of Sprinkle and Trickle Irrigation for twelve years at the university-senior level. I am confident that all students who completed this design course know not only how to design efficient and effective pressurized irrigation systems, but also know why they use the procedures that they use."

Drought Management on Farmland (Hardcover): Joan Sydney Whitmore Drought Management on Farmland (Hardcover)
Joan Sydney Whitmore
R4,604 Discovery Miles 46 040 Ships in 10 - 15 working days

At last, integrated management of drought on farms is dealt with in one comprehensive book. Although drought is a highly variable, near-universal natural phenomenon which has repercussions on a country's water and food supplies and many other sectors of the economy, there are many ways of avoiding, resisting and mitigating the effects of drought. Pro-active preparedness entails using the principles of risk management to upgrade the drought resistance of a farm systematically, and to have auxiliary contingency plans at the ready for use during unusually long droughts. The book provides tools for these strategies as it covers the management of water, soils, crops, rangeland, fodder and livestock, and many other drought-related topics. Audience: This book will be an important source of information for university and college staff and students in agricultural sciences, water and land use, environmental management, geography and risk management, and also farmers, agricultural advisors and policy makers.

R4,542 Discovery Miles 45 420 Ships in 10 - 15 working days

The increasing global demand for food and other agricultural products calls for urgent measures to increase water use efficiency which is, with plant nutrient availability, one of the two main limiting factors in crop production. Although only 20% of all cultivated land in the world is under irrigation, it provides 35-40% of all crop production. Because of higher yields under irrigated agriculture, investments for irrigation are usually a top priority. However, it has become a matter of serious concern in recent years that, despite their high co~ts, the performance of many irrigation projects has fallen short of expectations as a result of inadequate water management at both farm and system levels. Crop production increase has been well below the project targets. The greatest potential for increasing food and other agricultural products is the more efficient use of naturally occurring precipitation in conjunction with improved soil fertility management. Until recently, regardless of the amounts and distribution of rainfall, irrigation practices were used almost exclusively to supplement the amount of soil water stored in the root zone to such an extent that the available soil water never allowed the crop to suffer from water stress throughout the growing season. As a result, even today farmers still tend to over-irrigate to ensure a bountiful amount of water stored.

Managing Salinization - Institutional Analysis of Public Irrigation Systems (Hardcover, illustrated edition): W. Scheumann Managing Salinization - Institutional Analysis of Public Irrigation Systems (Hardcover, illustrated edition)
W. Scheumann; Translated by A. Weissbach, H. Boeddicker
R2,632 Discovery Miles 26 320 Ships in 10 - 15 working days

Salinization of soils is a major threat to irrigated agriculture and counteracts the targets of costly public infrastructure investments. In this study, salinization is regarded as the outcome of an institutional arrangement which impedes the effective implementation of well-known and well-established control measures be they technical, managerial or economic. In public irrigation systems neither the management units nor the farmers are offered any incentives towards the control of high groundwater levels and salinization if the management units are embedded in a highly centralized non-market institutional setting. The author answers the question under which conditions management units and irrigators are active in halting and reversing the process of salinization.

R1,953 Discovery Miles 19 530 Ships in 12 - 17 working days

Irrigation has been used for thousands of years to maximize the performance, efficiency and profitability of crops and it is a science that is constantly evolving. This potential for improved crop yields has never been more important as population levels and demand for food continue to grow. Recognising the need for a coherent and accessible review of international irrigation research, this book examines the factors influencing water productivity in individual crops. It focuses on nine key plantation/industrial crops on which millions of people in the tropics and subtropics depend for their livelihoods (banana, cocoa, coconut, coffee, oil palm, rubber, sisal, sugar cane and tea). Linking crop physiology, agronomy and irrigation practices, this is a valuable resource for planners, irrigation engineers, agronomists and producers concerned with the international need to improve water productivity in agriculture in the face of increased pressure on water resources.
