This book was released on 1987 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of a symposium on irrigation water delivery systems, held in Portland, Oregon, July 28-30, 1987. Sponsored by the Irrigation and Drainage Division of ASCE. This collection contains 34 papers on planning, operation, rehabilitation, and automation of irrigation water delivery systems. Papers respond to the need for water delivery flexibility to maximize on-farm yield and for water conservation through more effective on-farm use. Papers discuss how to upgrade, rehabilitate, or automate water delivery systems so that they can respond to changes in demand patterns, provide water users with reliable and flexible water supplies, be managed to achieve maximum firm water yield, and continue to be able to meet present and future demands.

Book Synopsis Fundamentals of Smallholder Irrigation by : B. Albinson
Download or read book Fundamentals of Smallholder Irrigation written by B. Albinson and published by IWMI. This book was released on 2002 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallholder irrigation systems–where farm sizes generally range from a fraction of a hectare to 10 hectares–pose special management problems, especially where the water available for irrigation is frequently less than the demand. The intensity of system adjustments required to meet individual farmer demands, and the administrative complexity of measuring and accounting water deliveries have generally proven excessive when attempting to meet “on demand†schedules, resulting in chaos (often characterized by illegal tampering with infrastructure, and vast differences of water use intensity at different locations in the system). The alternative–provision of a simple service, based on proportional sharing of available supplies on the basis of landholdings–has been resilient for many years over vast areas. The approach is based on a clear delineation between the part of the irrigation system that is actively managed (at various flow rates and water levels) and the part of the system that operates either at full supply level (with proportional division of water down to the level at which farmers rotate among their individual farms), or is completely shut. This operational design is known as a “structured†system, and has well-defined hydraulic characteristics, simplifying operation and management, in turn allowing a clearer definition of water entitlements and the responsibilities of agency staff and farmers. The approach is particularly suited to areas where water is scarce and discipline is needed to ration water among users. An additional benefit, which has been demonstrated in modeling studies using a well–proven model relating to water and yield, is that the productivity of water (which is more important than the more traditional productivity of land when water is scarce) is substantially increased when deficit irrigation is practiced–a widely observed and predictable response to rationed water supplies. Structured systems are most suited where water is scarce, clear definition of water entitlements is needed, management capacity is limited, and investment resources are limited. The approach to determining critical aspects of a structured system design is described in this report.

Book Synopsis Management of Irrigation and Drainage Systems by : Hector M. Malano
Download or read book Management of Irrigation and Drainage Systems written by Hector M. Malano and published by CRC Press. This book was released on 1999-01-01 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides an overview of the principles required for a service orientation in the management of irrigation and drainage systems. The material covered is designed to emphasize an area largely neglected in the irrigation and drainage management literature. The dominating philosophy underlying this book is that irrigation and drainage systems must be managed as a service business responsive to the needs and changing requirements of its customers. It is postulated that this service approach to the management of irrigation and drainage systems consitutes a key element of the startegy that is needed to improve the current level of performance of many irrigation and drainage systems worldwide. Enhanced performance of irrigation is a prerequisite if we are to face the enormous challenge of producing greater quantities of food to meet the demand of a growing population. This is particularly the case in an environment with increasing competition for water from industry and urban water users, set against mounting concerns about environmental sustainability.
Book Synopsis Performance Analysis of On-demand Pressurized Irrigation Systems by : Nicola Lamaddalena
Download or read book Performance Analysis of On-demand Pressurized Irrigation Systems written by Nicola Lamaddalena and published by Food & Agriculture Org.. This book was released on 2000 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the strong competition that is arising for water resources the modernisation of irrigation systems is becoming a critical issue. One of the alternatives to modernisation is the use of pressurised systems to replace part of the existing networks. This publication analyses the performance of pressurised irrigation systems operating on demand, and provides revised criteria for the design of such irrigation networks. For this purpose, new approaches and a computer program have been developed. The program has been tested in several field situations in the Mediterranean Basin and has demonstrated its usefulness not only by quickly identifying weak points in irrigation networks but also by identifying the power requirements of pumping stations needed to satisfy varying demand situations.

Book Synopsis Charging for Irrigation Services by : Frank van Steenbergen
Download or read book Charging for Irrigation Services written by Frank van Steenbergen and published by IWA Publishing. This book was released on 2006-11-01 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigation is the dominant consumer of fresh water world-wide, accounting for as much as 80% of use in many water-short countries. Two issues dominate the problems in water resources management generally, and especially the management of irrigation systems: scarcity of water to meet competing demands, and scarcity of funds to finance operation, maintenance and renewal of existing facilities. Various international conferences, donor policies and academic papers have pointed to the contribution that appropriate irrigation service charging systems can make to both problems. This book is unique in that it connects policy objectives in water pricing with the practicalities of a setting up an irrigation water charging systems. It discusses the different types of water charging systems as well as the basis for quantifying and calculating the charges in the real world. Based on practical experiences in a range of countries , it also looks at possibilities for cost rationalizations and developing a broad range of revenue streams. The book concludes with a systematic explanation on how to design an irrigation water charging system - looking at assessment, billing and improving collection performance.

This book was released on 2021-11-16 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resources are linked to the global challenges of food insecurity and poverty, as well as to climate change adaptation and mitigation. In line with the Sustainable Development Goals (SGD), FAO works towards several dimensions of sustainable development, including the promotion of coherent approaches to efficient, productive and sustainable water management, from farm to river basin scales. Accordingly, FAO is enhancing well-informed on-the-ground decision-making processes on water management through projects, knowledge advancement, information-sharing and tools development, such as AquaCrop, the FAO crop-water productivity model. This model assists in assessing the effects of environment (including atmospheric CO2 concentration) and management on crop production through the simulation of yield response to water of herbaceous crops. It is particularly suited to address conditions where water is a key limiting factor in crop production. In 2009, FAO officially launched AquaCrop, being the result of several years of collaborative work among scientists, water and crop specialists and practitioners worldwide, bringing together previously fragmented information on crop yields in response to water use and water deficit. AquaCrop has evolved over the different versions released since its first launch, but it always balances accuracy, simplicity and robustness. This has enabled it to remain faithful to its goal, i.e., to be a dynamic tool accessible to several types of users, mainly practitioner-type end users, in different disciplines and for a wide range of applications. In addition, AquaCrop may be considered a valuable tool by research scientists for analysis and conceptualization.
