Increasing the efficiency of water use and enhancing agricultural water productivity at all levels of the production chains are becoming priorities in a growing number of countries. In particular, shifting to modern on-farm irrigation practices can contribute to a substantial increase in both water use efficiency and water productivity. The objective of this handbook is to provide a practical guide on the use of pressurized irrigation techniques to farmers, irrigation technicians, and extension workers in the field. In this second edition, the handbook has been considerably revised, including new chapters on low-cost drip irrigation and pipe distribution systems for smallholders.--Publisher's description.

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.

FAO's Irrigation and Drainage Paper No. [Author] 63 introduced the MASSCOTE methodology in 2007, tailored for modernizing large-scale canal irrigation systems. [Author] With global interest shifting towards pressurized pipe systems, particularly in water-scarce regions, the need for a similar methodology became apparent. [Author] Pressurized systems offer advantages like on-demand irrigation, reduced water wastage, and environmental impact. [Author] However, they require complex management due to changing water demands. [Author] To address this, FAO developed the MASSPRES approach, building on MASSCOTE's principles. [Author] MASSPRES aims to assess and enhance the performance of pressurized irrigation schemes, introducing steps like the Rapid Appraisal Procedure (RAP) for system mapping. [Author] It offers innovative methods for evaluating pressures and discharges at farm hydrants under various operating conditions, replacing earlier statistical analysis approaches. [Author] MASSPRES incorporates indicators for capacity, reliability, distribution equity, sensitivity to change, and perturbation risks into user-friendly software. [Author] Practical examples from Egypt, Italy, Spain, and Tunisia showcase its effectiveness. [Author] As governments seek to improve water and food production amidst increasing water scarcity, adopting technologies like pressurized irrigation becomes crucial. [Author] MASSPRES provides a systematic framework for both upgrading existing systems and designing future ones, addressing the complexities of managing pressurized irrigation efficiently. [Author]

The present book intends to assess the performance of Pressurized Irrigation Network System (PINS), the effectiveness of institutional arrangements for management of PINS projects and the bottlenecks for their smooth functioning in India. Since Gujarat, Rajasthan, Maharashtra and Telangana are the leading states of the country promoting PINS and MIS, the study was planned as an all India coordinated study covering these four states. The WUAs in the study areas of the selected states were interviewed to capture the dynamics of community based irrigation management. Under different command areas, the study analysed system performance of PINS with MIS such as drip and sprinklers in terms of their functioning, costs and benefits, adoptability. The study finds beneficial impact of PINS investment on cropped area, irrigation area, farm production as well as water and energy savings. The book will be very useful for those who are interested in policies and governance issues related to irrigation water management in the country and the selected states in particular.

The design text, Sprinkle and Trickle Irrigation, opens up a new and clear window through which to view the physics, economics, design, and manage ment of pressurized irrigation systems. A broad array of system types and ap plications have been covered in detail to provide for complete understanding of systems design. Topics include soil-water-plant relations, general planning con cepts, hydraulics, economics, sizing, operation, maintenance, and special uses. Pressurized irrigation system types covered include hand-line, wheel-line, solid set, traveler, center-pivot, linear-moving and big-gun-sprinkler systems, pump ing systems, and a broad array of trickle system components. The work in this text culminates earlier major works by Jack Keller on the W. R. Ames Company Irrigation Handbook (1967), Rain Bird Sprinkler Man ufacturing Corp. 's Trickle Irrigation Design (1975), and the USDA-Soil Con servation Service's National Engineering Handbook, Section 15: Irrigation Chapter 11: Sprinkle Irrigation (1983) and Chapter 15: Trickle Irrigation (1984). These earlier works form the foundation upon which the majority of currently used design texts are based. The years of design and troubleshooting experiences of the authors and wide ranges of environments and design appli cations in which they have worked have resulted in the substance and robustness of this text in stated relationships and procedures.

Micro irrigation, also known as trickle, drip, localized, high frequency, or pressurized irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done throug

In the short water supply environment of Pakistan, fanners try to minimize the gap between demand and supply of canal water by extracting groundwater for irrigation purposes. However, saline groundwater upconing may occur in response to fresh groundwater withdrawals from unconfined aquifer underlain by salty groundwater. Skimming well technology can help in control1ing this upconing phenomenon. However, in most cases, the small discharges of such wells cannot be efficiently applied on surface irrigated croplands. Pressurized irrigation systems use smal1 discharge effectively, but the cost and availability of equipment in the local market are the constraints. Root zone salinity is also expected to increase if this skimmed groundwater is used for irrigation purposes, particularly in the absence of proper salinity management practices. To address these issues, International Water Management Institute (lWMI), Water Resource Research Institute (WRRI) and Mona Reclamation Experimental Project (MREP) collaborated to undertake an applied research project on Root Zone Salinity Management Using Fractional Skimming Wells with Pressurized Irrigation. This project was started in March 1999 and concluded in June 2003. The National Drainage Program (NDP), Research Component -WAPDA funded this project

Detailed hydro-geological investigations were carried out while implementing SCARPs in the Chaj Doab. These investigations yielded a data set of groundwater quality at different depths of the aquifers (spatial) especially in the SCARP-II saline zone. In MREP area, 138 public tubewells, having strainers from 30-35 m till 60-75 m depth of the aquifer, were installed during the 1970s to help meet the irrigation water demand at farm level. The MREP, who was made responsible for operation and maintenance of these deep tubewells, continuously monitored the performance of these tubewells as well. Therefore, the pumped groundwater quality data (temporal) of these spatially distributed tubewells was also available. This data availability served as a basis for site selection using GIS analysis.The GIS analysis, which was used in classifying different groundwater quality zones, helped in selecting fifteen villages (thirteen in MREP area and two in SCARP-II saline zone) that have hydro-geological potential for installing and operating skimming wells. In these selected villages, preliminary survey was carried out to get information on the farmers' willingness to use skimming well technology. Based on the GIS analysiS and preliminary survey, different sites in six villages (two in SCARP-II saline zone, and four in SCARP-II non-saline zone) were selected to carry out the Diagnostic AnalysiS (DA) for investigating the hydro-salinity and hydro-geological conditions of the aquifer. Based on the DA results, four villages for the Participatory Rural Appraisal (PRA) to assess farmers' practices and perceptions in opting for skimming well technologies.
