Book Description
Outlines the IWMI Water Balance Framework, which identifies sources, uses and reuses of water. The framework will be of interest to those involved in the design of irrigation projects and in the formulation of improvements to existing infrastructure of operational rules. Managers of irrigation projects will also find it useful for interpreting water use efficiency, or for identifying interventions to improve the efficiency and sustainability of their projects.

A diagnostic model framework for water use in rice-based irrigation systems
Author: Wilfried Hundertmark
Publisher: IWMI
ISBN: 9290905298
Category : Rice
Languages : en
Pages : 57
Book Description
The paper presents a framework for water use in rice-based irrigation systems, which is based on linear programming (LP). This framework intends to facilitate improved understanding of a system's internal and external conditions and the constraints to productive use of the available land and water resources, and thereby create a reference for the assessment of the physical, economic and environmental performance of a given system. The framework is conceived as a tool that is used interactively in technical group sessions with farmers, system operators and extension workers, where structured discussions lead to improved data confidence, and understanding of complex irrigation systems.

Accounting for Water Use and Productivity
Author: David Molden
Publisher: IWMI
ISBN: 929090349X
Category : Irrigation
Languages : en
Pages : 26
Book Description
This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and increasing water productivity; developing a better understanding of present patterns of water use and impacts of interventions; improving communication among professionals and communication to non-water professionals; and improving the rationale for allocation of water among uses. It is expected that with further application, these water accounting concepts will evolve into a robust, supporting methodology for water basin analysis.

Publisher: IWMI
ISBN: 9290903546
Category : Irrigation
Languages : en
Pages : 50
Book Description
Presents two alternative scenarios of water demand and supply for 118 countries over the 1990 to 2025 period and develops indicators of water scarcity for each country and for the world as a whole. This study is the first step in IWMI’s long-term research goal: to determine the extent and depth of water scarcity, its consequences for individual countries and what can be done about it.

Institutional Design Principles for Accountability in Large Irrigation Systems
Author: Douglas J. Merrey
Publisher: IWMI
ISBN: 929090335X
Category : Irrigation
Languages : en
Pages : 34
Book Description
Argues that single irrigation systems managed by autonomous system-specific organizations accountable to their customers, perform better and are more sustainable than those managed by agencies dependent on the government, or by agencies responsible for multiple systems. Selected cases are reviewed and the plausibility of this hypothesis established. General recommendations are made for policy makers designing irrigation reform programs.

Water Productivity in Agriculture
Author: J. W. Kijne
Publisher: CABI
ISBN: 1845933397
Category : Crops and water
Languages : en
Pages : 354
Book Description
First title in a major new seriesAddresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental securityDraws from scientists having a multitude of disciplines to approach this important problemIn a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.
