Book Irrigation Fundamentals

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.

Further, it examines multi-criteria decision making for irrigation management and the appraisal of agricultural lands for irrigation in hot, sub-humid regions. Features: Presents comparative analysis to aid in the selection of the most appropriate types of irrigation systems according to land characteristics. Includes numerous practical case studies. Offers parametric evaluation systems for irrigation purposes. Considers data from semi-arid zones, each with different sub-climates. Focusing on semi-arid land, the book highlights parametric evaluation systems for irrigation purposes, along with the use of analytical hierarchy processes integrated with GIS to determine which systems are best suited. This comprehensive and well-illustrated handbook will be of great interest to students, professionals, and researchers involved with all aspects of irrigation in semi-arid regions.

Book Typology of Farm Households and Irrigation Systems

Download or read book Typology of Farm Households and Irrigation Systems written by Hiroyuki Takeshima and published by Intl Food Policy Res Inst. This book was released on 2013-04-25 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigation is considered an important factor for agriculture and food security. Knowledge gaps, however, still exist with regard to how farmers in Africa south of Sahara, including Nigeria, are using irrigation. Given the diverse agroecological and socioeconomic environment in countries like Nigeria, understanding the diverse patterns of irrigation use and their associations with household characteristics is important in designing how irrigation can contribute to the agricultural transformation. This report summarizes the typology of farm households and irrigators in Nigeria. We apply a cluster analysis method to the Living Standard Measurement Survey (LSMS)—Integrated Survey on Agriculture data and various secondary data. We also compare the costs and inputs used across different irrigation crops, as reported in Nigeria. Findings indicate that the three major irrigation systems in Nigeria are (1) labor-intensive diverted stream irrigation of rice, (2) supplementary irrigation of coarse grains and legumes using groundwater, and (3) dry season irrigation of vegetables. Each crop is irrigated during a specific season and using a specific water source and irrigation system. Farmers’ choice of irrigation system tends to depend on many factors. For example, in the South, tractorization is often a necessary precondition for rice irrigation. In the North, intensive irrigation of rice and vegetables may make sense only if labor is cheap, whereas irrigation of sorghum and legumes is supplementary and may not affect farm households’ behaviors. Although more rigorous studies are needed in the future, observed patterns of irrigation use in Nigeria indicate that the policies aiming to raise agricultural productivity and to develop the value chains of key crops may need to be based on an understanding of why irrigation is used in specific ways in different systems and of what the key constraints in scaling up such systems in other locations are.
