Book Synopsis A diagnostic model framework for water use in rice-based irrigation systems by : Wilfried Hundertmark
Download or read book A diagnostic model framework for water use in rice-based irrigation systems written by Wilfried Hundertmark and published by IWMI. This book was released on 2003 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Water Balance Study written by and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There is widespread recognition that water resources, including groundwater and surface water, are coming under pressure from increasing demand of water uses. Water supply systems have often been developed in an unsustainable way, threatening vital social and economic developments. As a result many governments have been reforming water resources management to adopt the approach known as Integrated Water Resources Management (IWRM). An important objective of this training manual is to address the factors that influence water storage and how water can be used in the most beneficial way based on available water budget which is the output from a water balance study. The goal of this manual is to introduce the broader framework of water management to be used by the water engineers/professionals, mangers so that they can identify the various challenges of water management and take appropriate measure to mitigate or eliminate the problems. Various tools have been introduced to estimate water budget, pros and cons of each tools were discussed. The manual also highlight the impact of climate change on water sector and various adaptive measures that can be used as potential mitigation measures. It also emphasis the issue of public participation and various stakeholders' roles for water management. Finally it explains the importance on information management for processing various hydrological data and the process of disseminating information among various stake holders.

Book Synopsis Accounting for Water Use and Productivity by : David Molden
Download or read book Accounting for Water Use and Productivity written by David Molden and published by IWMI. This book was released on 1997 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Water for Agriculture by : Stephen Merrett
Download or read book Water for Agriculture written by Stephen Merrett and published by CRC Press. This book was released on 2003-08-02 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: World population is set to increase by a third in the next 25 years, with no corresponding increase in global rainfall. About seventy per cent of the world's abstracted water is used in farming and therefore the economics of irrigation is becoming an increasingly important issue for sustainable development. Water for Agriculture provides a thorough overview of this highly topical subject, written in a clear and accessible style. The Scope of the book is wide both in its analysis and in its geographical coverage. Topics covered include the infrastructure, operation and maintenance of irrigation service supply, the supply of drainage services, economic cost benefit analysis, water resource planning at the regional scale, political economy and irrigation policy. The content of Water for Agriculture is enhanced by numerous tables, diagrams, and in-depth case studies. This book will be an essential read for those professionals involved in the planning of water resources, and for advanced students studying this topic as part of agriculture, development studies, economics, engineering, environmental science, geography, hydrology and planning courses.
Book Synopsis The Price of Water by : Stephen Merrett
Download or read book The Price of Water written by Stephen Merrett and published by IWA Publishing. This book was released on 2007-08-31 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Second Edition of the Price of Water expands on the coverage of the first edition and ambitiously develops the theme of the proper management of river basins, both with respect to the control of rivers’ water quality and the defence of their quantitative flows from source to sea. Using the hydrosocial balance concept of the first edition, and the grand theory of catchment water deficits, a remarkable breakthrough is made in understanding how river flows are destroyed by human society. Drawing on extensive empirical research into the Kafue River Basin and the Thames River Basin, it is shown that the exhaustion of river flows that we see on a world-wide scale can be explained by just five measurable ‘drivers’ to basin surplus and basin deficit. Moreover, by specifying the key drivers and measuring their value, the basis is provided for economic, engineering and land management strategies that will reverse river basin destruction. Bringing together 20 papers previously published in refereed journals, The Price of Water provides information that many readers would not otherwise have been able to access to through their professional and academic libraries. The scope of the book is broad, dealing with a diverse range of subjects such as regional and catchment planning and integrated water resources management. Topics considered include: both water quantities and qualities drought management the "virtual water" controversy farmers water-rights the economic demand for water the design of abstraction charges the cost and use of irrigation water the design of effluent charges the "willingness-to-pay" methodology catchment water deficits water resource impacts of new property construction water leakage impact on river basins managing water quality within EC directives.
