This manual covers the technical design and operational aspects of high efficiency (pressurized) irrigation system in a brief and comprehensive way. The first volume covers a detail discussion of pressurized irrigation systems including their classifications, selection criteria and components followed by basics of design. Design proforma for design of drip and sprinkler irrigation system has been discussed in detail covering the procedure for collection of necessary field data required for proper system design. Hydraulic principles have also been covered in detail for proper selection of pipe network and pumping unit. Design procedure has been elaborated with solved examples. Second volume of this manual covers the operational part of pressurized irrigation systems, which includes general maintenance and tips for durability and sustainability of high efficiency irrigation system equipments. It also covers the vigilance and checking during system operation, care after completing a crop season, care of prime movers, systemre-adjustments, clogging and its remedies, chemigation including acid treatment and chlorination, maintenance tips of water storage tanks, general trouble shooting and remedies. A list of tables and diagrams is also provided for the ease of users. This manual will provide a general guideline to project technical staff and contractors for proper design and smooth field operations of high efficiency irrigation system sites and it will also be helpful for effective post installation services and getting the desired results from high efficiency irrigation systems.

Proper design and installation are essential to provide a drip irrigation system that can be managed with minimal inputs and maximum profit. Because drip irrigation can apply precise amounts of water and chemicals, constraints associated with the plants, soil, water supply, and management must be considered in the design, installation, and management processes.

If we look at the existing irrigation methods used today in the country, then they are divided into: ground, rainfall, underground or underground, drip and spray. Basically, they are transferred to the irrigation field in two forms: through gravity and pressure irrigation systems. Naturally, a gravity irrigation system is economically more expensive than a low pressure irrigation system. However, from a performance appraisal stand point, pressure irrigation methods are less efficient and have serious disadvantages

AbstractThis paper, based on historical research on irrigation administration in the Dongping area and on-site investigations into its current state, explores the benefits and problems produced by two institutional changes. As a common pool resource situation, irrigation systems’ “provision” and “appropriation” are two separate issues; any institutional change must thus offer two different solutions. The study concludes that the participatory changes undertaken in the Dongping irrigation area failed, in the end, to resolve the problem of irrigation system sustainability. In particular, it proved difficult for collective action to take place around provision, which led to difficulties in operating the irrigation system.

Historical surface irrigation of pastures in the Dutch province of Noord-Brabant: visible traces of a failed experiment In the second half of the 19th century, some major changes occurred in the water management of the eastern and southern provinces of the Netherlands. Unlike the low-lying western parts of the Netherlands which were characterised by polders and had a long history of formal water boards, the higher eastern and southern parts of the Netherlands were characterized by brook systems and sandy soils, and had no centralised water boards until 1850. From the 1850s onward, water boards were introduced in these higher regions as well, and agronomical scientists and organisations like the Nederlandse Heidemaatschappij endeavoured for the modernisation of agricultural water management. One of their priorities was the introduction of modern forms of surface irrigation of pastures, in order to increase crop yields. In various places modern irrigation systems were constructed. From the 1900s onward, these systems were abandoned due to the introduction of new chemical fertilizers, among others. This article describes the construction and abandonment of one of these modern irrigation systems that was located in Liempde, in the province of Noord-Brabant. The local farmers were not interested in the new technique, and within a few years the system was transformed in a poplar plantation. Nowadays, the area is part of a nature reserve. Nonetheless, the global layout of the irrigation system is still visible.

Oriental philosophers have given top priority to food for orderly state affairs as well as personal wellbeing. In past, Nepal had a strong agricultural economy based on indigenous Farmer Managed Irrigation System (FMIS). State policy helped promote these systems. But contemporary Nepal opted for state control on irrigation water by building large scale public irrigation systems. In the last 43 years of planned development (1957-2002), the government has spent 70% of US$1.3 billion on these systems, covering 30% of the irrigated area in the country; the remaining 70% is with the FMIS. Despite the investment, these systems neither promoted themselves as an enterprise nor helped enhance agricultural productivity leading to social insecurity. This social insecurity is reflected in the country's increasing import of food, mass workforce exodus for employment abroad, and added socio-economic vulnerability due to climate change.Donor and government recommendations centered on (i) expansion of irrigated area, (ii) irrigation management transfer, and (iii) agriculture extension seem to have failed in Nepal. These failures asked for alternative institutional development solutions, whereas public irrigation systems are (i) localized to establish system's operational autonomy with ownership and governance, (ii) treated as a rich resource-base with water, land and labor, and (iii) recognized as cooperative enterprise of local stakeholders by law with authorities to enter into joint actions with relevant partners for promoting commercialization and environmental quality of irrigated agriculture.DOI: http://dx.doi.org/10.3126/hn.v11i1.7223 Hydro Nepal Special Issue: Conference Proceedings 2012 pp.95-99
