Download or read book A Proposed Framework for Irrigation Management Transfer in Iran written by Mehmood Ul Hassan and published by IWMI. This book was released on 2007-01-01 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iran is facing a serious water scarcity and the Government of Iran is trying to implement technical and institutional measures to meet the challenge. One of the key strategies being persuaded by the Iranian authorities is the devolution of management responsibility to users. Thus, irrigation management transfer (IMT) has been adopted as a key strategy to improve the operation and maintenance, and thereby reduce losses, and enhance the sustainability of irrigation infrastructure. However, IMT efforts are at an inception stage and are largely happening in areas where infrastructure is under rehabilitation. The key objective of this paper, thus, was to review the ongoing IMT efforts in the two provinces of Iran, as well as the lessons from the neighboring countries, and propose a viable framework for implementing IMT. To get the first hand information of the IMT activities in Iran, field visits were carried out in the provinces of Qazvin and Kermanshah where two big pilot projects are being carried out. For comparative analysis of the IMT situation in neighboring countries, a comprehensive review of experiences in Sri Lanka, India, Pakistan, Turkey and Central Asia was carried out through literature survey. Based on the synthesis of lessons from this exercise, the paper proposes a framework for irrigation management transfer in Iran.
Download or read book Water Use Efficiency of Wheat written by Abolfazl Nasseri and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supplemental irrigation is necessary for obtaining potential yield of wheat in rainfed areas. Irrigation and rainfall water use efficiencies are important in such areas, which are calculated as grain yield divided by rainfall and/or supplemental irrigation water. Therefore, water use efficiency of wheat under supplemental irrigation and rainfed conditions were investigated for the north of Iran in this book. Soil and water researchers, engineers and students can use findings of this study.
Download or read book Supplemental Irrigation in the Near East and North Africa written by Eugene R. Perrier and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the product of an ICARDA project to define supplemental irrigation in the Near East and North Africa. In cooperation with the Food and Agriculture Organization of the United Nations (F AO) a meeting was held in Rabat, Morocco, on 7-9 December 1987, entitled "Regional Consultation on Supplemental Irrigation"; specialists from 11 different countries were brought together to discuss priorities for supplemental irrigation within their specific regions. The participants were asked to focus on developing an information base using both primary data, results of surveys administered to district level agricultural personnel, and secondary data sources with a particular interest in the application of state-of-the-art knowledge and technology to the problems of supplemental irrigation. The authors have willingly and thankfully responded to the suggestions and criticisms of Ms Kate Ward, Institute of Irrigation Studies, Department of Civil of Southampton, U. K. , who accepted the soporific Engineering, University position of Review Editor and performed miracles. Chapter 2 and parts of chapters 15 and 16 are a partial rendering of a forthcoming book on systems analysis by Janice R. Perrier. The authors recognize the inclusion of this material which outlines the basic philosophical perspective of supplemental irrigation as utilized in the book. The assistance of Mr. Maurice Saade, Agricultural Economist is greatly appreciated for the understanding of Chapter 14. The section on the phenology of cereals near the end of chapter 4 was written by Mr.

Download or read book Modeling Wheat Production from Nitrogen Fertilization written by Abolfazl Nasseri and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The north of Iran is one of the main regions for agricultural production but the occurred precipitation is insufficient to meet wheat requirement. Consequently, supplemental irrigation is necessary for obtaining potential yield of wheat in rainfed areas. In addition, nitrogen fertilization can improve water use efficiency in such areas. Therefore, supplemental irrigation and nitrogen fertilization effects on production of winter wheat under rainfed climate condition were investigated in this book. Soil and water researchers, engineers and students can use findings of this study.

This book was released on 2005-03-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Yield gap analysis of field crops written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-06-29 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: To feed a world population that will exceed 9 billion by 2050 requires an estimated 60% increase over current primary agricultural productivity. Closing the common and often large gap between actual and attainable crop yield is critical to achieve this goal. To close yield gaps in both small and large scale cropping systems worldwide we need (1) definitions and techniques to measure and model yield at different levels (actual, attainable, potential) and different scales in space (field, farm, region, global) and time (short and long term); (2) identification of the causes of gaps between yield levels; (3) management options to reduce the gaps where feasible and (4) policies to favour adoption of sustainable gap-closing solutions. The aim of this publication is to critically review the methods for yield gap analysis, hence addressing primarily the first of these four requirements, reporting a wide-ranging and well-referenced analysis of literature on current methods to assess productivity of crops and cropping systems.

This book was released on 2020-07-22 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Irrigation System Selection for Semi-Arid Regions compares the various types of available irrigation systems for different regions and conditions, and explains how to analyze field data to determine the suitability of the land for surface, sprinkle, or drip irrigation systems. The book focuses on strategies for irrigation development and management and examines deficit irrigation and partial root-zone drying systems. Also, solute leaching modeling under different irrigation systems, soil moisture conditions, and organic fertilizer application in arid areas are discussed. 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.
