Multiple Uses of Water in Irrigated Areas by International Water Management Institute Pdf

Water is being transferred out of agriculture to meet the growing demand in other areas, often without an agreement of or compensation to farmers with irrigated land and water rights. Furthermore, there is a failure to recognize that irrigation systems supply water not only for the main fields, but also for domestic uses, home gardens, trees and other permanent vegetation, and livestock. Other productive uses include fishing, harvesting of aquatic plants and animals, and a variety of other enterprises such as brick making. In addition, irrigation systems can have a positive or negative effect on wildlife habitats. Thus, the withdrawal of water affects the rural household, rural economy, and the environment in a number of ways. This paper argues that to ensure efficient, equitable, and sustainable water use, to reduce poverty and improve the well-being of the community, irrigation and water resources policies need to take into account all uses and users of water within the irrigation system. The multiple uses of water in the Kirindi Oya irrigation system are examined in this paper. An interdisciplinary group of scientists have investigated a number of areas including water accounting, water quality, household water use, the valuing of water for alternative uses, and the complementarities, competition, and conflicts among uses and users.

Irrigation Management by Dr. Martin Burton Pdf

In many countries irrigated agriculture consumes a large proportion of the available water resources, often over 70% of the total. There is considerable pressure to release water for other uses and, as a sector, irrigated agriculture will have to increase the efficiency and productivity of its water use. This is particularly true for manually operated irrigation systems managed by government agencies, which provide water for a large number of users on small landholdings and represent 60% of the total irrigated area worldwide. --

Water Requirements for Irrigation and the Environment by Marinus G. Bos,R. A. L. Kselik,Richard G. Allen,David Molden Pdf

Irrigated agriculture produces about 40% of all food and fibre on about 16% of all cropped land. As such, irrigated agriculture is a productive user of resources; both in terms of yield per cropped area and in yield per volume of water consumed. Many irrigation projects, however, use (divert or withdraw) much more water than consumed by the crop. The non-consumed fraction of the water may cause a variety of undesirable effects ranging from water-logging and salinity within the irrigated area to downstram water pollution. This book discusses all components of the water balance of an irrigated area; evapotranspiration (Ch.2), effective precipitation (Ch.3) and capillary rise from the groundwater table (Ch.4). Chapter 5 then combines all components into a water management strategy that balances actual evapotranspiration (and thus crop yield) with the groundwater balance of the irrigated area (for a substainable environment). Chapter 6 presents CRIWAR 3.0, a simulation program that combines all water balance components into a single simulation procedure. The chapter describes the use of the CRIWAR software for developing water requirement tables and other useful information based on the selected water management strategy. This version greatly expands upon the capabilities of previously published programs.

Multiple Uses of Water Services in Large Irrigation Systems by Daniel Renault,Robina Wahaj,Stef Smits Pdf

"This publication expresses the rationale for multiple use of water services for large irrigation systems and demonstrates how managers can optimize, rather than simply tolerate, multiple uses. It also illustrates how consideration and appropriate management of multiple uses can benefit an irrigation system by improving performance and enhancing sustainability. The aim is to provide readers - irrigation managers and designers - with guidelines, steps to follow and leads that will allow them to perform multiple uses or services investigations in their own irrigation systems unearthing all services, the obvious and the hidden, and to document them using local data and surveys"--Publisher's description.

In December 2002, a group of specialists on water resources from the United States and Iran met in Tunis, Tunisia, for an interacademy workshop on water resources management, conservation, and recycling. This was the fourth interacademy workshop on a variety of topics held in 2002, the first year of such workshops. Tunis was selected as the location for the workshop because the Tunisian experience in addressing water conservation issues was of interest to the participants from both the United States and Iran. This report includes the agenda for the workshop, all of the papers that were presented, and the list of site visits.

Environmental water needs and impacts of irrigated agriculture in river basins: A framework for a new research program by Smakhtin, V. Pdf

The intention of this paper is to develop a framework for a new IWMI research program on environmental water requirements of aquatic ecosystems and environmental aspects associated with irrigated agriculture in river basins and wetlands. The program will be implemented primarily in the context of developing countries, but the paper also examines research questions, which are of general importance for eco-hydrology and environmental water resources management. At the same time, it does not purport to be a comprehensive coverage of the environmental water research field but is designed primarily for attention of specialists dealing with wetlands, water resources management and sustainable agricultural development within sister CGIAR centers and other similar international agencies. It is envisaged that some ideas for future research presented in the paper will also be of interest to hydrologists and ecologists engaged in developing the concepts of environmental water requirements of aquatic ecosystems. The introduction of the paper sets up the purpose of the document. This is followed by a description of a framework, which links different levels of water resources use and conservation of natural aquatic systems with various management interventions. The main focus areas of the proposed research are then discussed. They include estimating water requirements of aquatic ecosystems, evaluating scenarios of development and impacts of irrigated agriculture on rivers and wetlands, allocating water with the consideration of environmental thresholds, etc. The paper also discusses possible research activities, which are associated with these focus areas and presents examples of specific research projects that could be pursued internally or in partnership with other national and international institutions.

Wastewater Use in Irrigated Agriculture by Christopher Scott,Naser Faruqui,Liqa Raschid-Sally Pdf

The use of urban wastewater in agriculture is receiving renewed attention, with the increasing scarcity of fresh water resources in many arid and semi-arid regions of the world. Wastewater is a low-cost alternative to conventional irrigation water, although it may carry health and environmental risks. This book critically reviews experience worldwide of these issues. Emphasis is placed on untreated wastewater use by means of field-based case studies from Asia, Africa, the Middle East and Latin America. It brings together a range of perspectives including economic, health, agronomic, environmental, institutional, and policy dimensions.

Safe Use of Wastewater in Agriculture by Hiroshan Hettiarachchi,Reza Ardakanian Pdf

This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.

The use of solar energy in irrigated agriculture by Salman, M., Abdelfattah, A., Ahmad, W., Simongini, C. Pdf

In the last decade, solar energy has experienced a rapid growth, which brings both environmental and economic benefits. In many countries, there is still no electricity grid extension in rural areas, and in the absence of a reliable electricity supply, farmers have to resort to diesel-based pumping irrigation systems. The solar photovoltaic (PV) system generates clean energy and eliminates the risk of environmental pollution in the form of oil spills, contaminated soil and carbon dioxide emissions. Operation and maintenance of the solar PV pumping system is a technical job that requires specialized knowledge and information to keep the system in working condition and sustainable and in working conditions. For this purpose, this sourcebook is designed to provide information on the design, operation, inspection, troubleshooting, and maintenance of solar PV pumping systems.
