This book was released on 1996-11-04 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigated agriculture has played a critical role in the economic and social development of the United States--but it is also at the root of increasing controversy. How can irrigation best make the transition into an era of increasing water scarcity? In A New Era for Irrigation, experts draw important conclusions about whether irrigation can continue to be the nation's most significant water user, what role the federal government should play, and what the irrigation industry must do to adapt to the conditions of the future. A New Era for Irrigation provides data, examples, and insightful commentary on issues such as Growing competition for water resources. Developments in technology and science. The role of federal subsidies for crops and water. Uncertainties related to American Indian water rights issues. Concern about environmental problems. And more. The committee identifies broad forces of change and reports on how public and private institutions, scientists and technology experts, and individual irrigators have responded. The report includes detailed case studies from the Great Plains, the Pacific Northwest, California, and Florida, in both the agricultural and turfgrass sectors. The cultural transformation brought about by irrigation may be as profound as the transformation of the landscape. The committee examines major facets of this cultural perspective and explores its place in the future. A New Era for Irrigation explains how irrigation emerged in the nineteenth century, how it met the nation's goals in the twentieth century, and what role it might play in the twenty-first century. It will be important to growers, policymakers, regulators, environmentalists, water and soil scientists, water rights claimants, and interested individuals.

Available in PDF, EPUB and Kindle. Book excerpt: There is no doubt that irrigation makes a major contribution to agricultural production, making a whole range of crops viable in an otherwise unreliable climate and helping insure against drought. However irrigation does not automatically guarantee a profit and acclaim, it is a high cost exercise, using water from increasingly scarce supplies, and contributes to environmental concerns of the community. Many of the pressures facing some irrigators have been caused by a lack of understanding in the past of best practices necessary in design, installation and management. Alternative methods of irrigation are presented, emphasising the characteristics of each that may make them suitable (or unsuitable) for particular situations. The range of crops under irrigation is very wide, and so too is the range of methods available to get water to them. Horticultural crops are included as well as broadacre crops. This section is followed by technical information of the various components that make up an irrigation system, and their installation. Irrigation is concerned with providing the optimum soil moisture conditions for plant growth. So to is drainage, in that too much water in the soil will retard growth. Many of the concepts surrounding irrigation are applicable to a consideration of drainage, so the book discusses that technology as well.

Download or read book Irrigation Fundamentals written by George H. Hargreaves and published by Water Resources Publication. This book was released on 1998 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: IRRIGATION FUNDAMENTALS is a comprehensive text on the basic principles and practices of applied agricultural irrigation. Written over a period of more than 10 years, it is based on the authors'' extensive experience in farming, consulting, research, teaching, and other related agricultural activities. The book is for use by teachers of introductory courses in irrigation, farmers who have some basic technical knowledge, and for administrators who need a general understanding of irrigation as an aid for policy decisions in water resource development and planning. Various factors that influence crop yield and production including climate, fertility, water, drainage, and agronomic practices are addressed. The various irrigation methods such as border, basin, contour, furrow, sub, sprinkle, and drip or trickle are described; and conditions are given for selection of the appropriate method to use. Recent developments and new technology are included herein when they have obvious practical applications, but for the most part the material presented in this book is based on well established principles and practices. Much of the content is very practical and much is essentially nontechnical. Nevertheless, some of the material covered in this book goes beyond the basic concepts in an attempt to better describe the relationships and techniques employed by irrigation scientists and irrigation engineers.From the Preface: The future of the world depends very much on how we manage natural resources. Since the year 1900 there has been a ninefold increase in global carbon emissions from burning fossil fuels, and the world population has increased about 3.7 times in this century. Vast areas of forests have been destroyed, and irrigated lands now produce 40% of the food supply. Due to depletion of groundwater reserves and an increase in population, irrigated area per capita is declining. Consequently, the irrigation of additional alluvial lands is a strategic necessity for all of humankind. Much of the alluvial lands cannot be made productive without prior development of water resources through flood control, drainage, and irrigation. The production of electricity through hydropower and the production of alcohol fuel from irrigated crops, as has been practiced for many years in Brazil, can slow the increase in carbon emissions. Such diverse developments are typically not separable; rather, they must be considered as integral parts of a comprehensive development plan. The conservation of natural resources and increasing productivity of irrigated lands are also strategic necessities. Much of the current technology is highly transferable and crop yields can be significantly increased on lands already under irrigation.The authors have worked in many countries in connection with resource inventories, teaching, and the planning, development and use of irrigation as a tool for increasing production and providing employment. They have written extensively and have been honored for their achievements. They have considerable experience with everything from primitive low-technology irrigation developments to highly developed irrigation in the USA and in dozens of countries around the world. Both of the authors have dedicated their careers to teaching, research, and consulting in agricultural irrigation and water resources development and planning. It is their hope and expectation that this book will provide incentives for investigating and documenting land and water resources, improving development, increasing crop yields, conserving resources, and improving the environment.

Available in PDF, EPUB and Kindle. Book excerpt: Arid Land Irrigation in Developing Countries: Environmental Problems and Effects covers the proceedings of the International Symposium on Arid Land Irrigation, held in Alexandria, Egypt on February 16-21 1976. This book is organized into eight sections encompassing 46 chapters. The opening section deals first with the benefits of arid land irrigation and the effective use of water in irrigated agriculture. This section also tackles the public health and socio-economic impacts of irrigation, as well as the planning and managing of irrigation and drainage systems. The next section discusses the results of some case studies on arid land irrigation, such as in districts in Mexico, Iran, and Egypt. Other sections explore the influence of irrigation on changes in hydrological processes and cycle, soil fertility, water quality, and biological balances. The closing sections consider the human problems in irrigation areas, with an emphasis on the problem of schistosomiasis and malaria. These sections also look into the viewpoints of specialist agencies of the United Nations on arid land irrigation. This book will be of value to agriculturists, economists, and researchers.
