The U.S

Vegetables are grown throughout the U.S. on various soil types and in various climates. Irrigation is essential to supplement rainfall in all areas to minimize plant water stress. In the U.S., irrigated vegetable production accounts for about 1.9 million ha or 7.5% of the irrigated area. California, Florida, Idaho, Washington, Texas, Nebraska, Oregon, Wisconsin, and Arizona account for 80% of the U.S. production of irrigated vegetables. In the U.S., surface and subsurface (seepage) irrigation systems were used initially and are currently used on 45% of all irrigated crops with a water use efficiency of 33%. Sprinkler or overhead irrigation systems were developed in the 1940s and are currently used extensively throughout the vegetable industry. Sprinkler systems are used on 50% of the irrigated crop land and have a water use efficiency of 75%. In the late 1960s, microirrigation (drip or trickle) systems were developed and have slowly replaced many of the sprinkler and some of the seepage systems. Microirrigation is currently used on 5% of irrigated crops. This highly efficient water system (90% to 95%) is widely used on high value vegetables, particularly polyethylene-mulched tomato (Lycopersicon esculentum), pepper (Capsicum annuum), eggplant (Solanum melongena), strawberry (Fragaria ×ananassa), and cucurbits. Some advantages of drip irrigation over sprinkler include reduced water use, ability to apply fertilizer with the irrigation, precise water distribution, reduced foliar diseases, and the ability to electronically schedule irrigation on large areas with relatively smaller pumps. Drip systems also can be used as subsurface drip systems placed at a depth of 60 to 90 cm. These systems are managed to control the water table, similar to that accomplished with subsurface irrigation systems, but with much greater water use efficiency. Future irrigation concerns include continued availability of water for agriculture, management of nutrients to minimize leaching, and continued development of cultural practices that maximize crop production and water use efficiency.

Drought conditions make landscape irrigation and reducing water use top-of-mind for many Floridians. Encouraging wise water use is of particular importance to the smart irrigation industry and water policy makers. This 5-page fact sheet written by Hayk Khachatryan, Alicia Rihn, Dong Hee Suh, and Michael Dukes and published by the UF/IFAS Food and Resource Economics Department pinpoints key attributes and barriers affecting consumers' irrigation purchases and their adoption of smart irrigation technologies. https://edis.ifas.ufl.edu/fe1080

A Performance

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.

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

Genuine inclusive participation in the self-governance of communal irrigation systems remains a challenge. This article analyses the mechanisms of participation in irrigation water users’ associations (WUAs) with focus on women as leaders of those organizations by drawing on cases from a comparative, multicase mixed-method study in Ethiopia and Argentina. After having being a topic for decades in gender and development debates, in many irrigated areas of the world, WUAs continue to be male dominated at all levels, especially in influential positions. Findings in this article suggest that despite large socio-economic and cultural differences, the current water management systems in both research locations reinforce problems of unequal gender participation; women have more obstacles and constraints in establishing equal access in membership, participation, and decision making in irrigation management. The lack of inclusive participation and the low representation of women in leadership roles lead to WUAs being poorly rooted in their community of users. Incomplete social rootedness of WUAs jeopardizes their effectiveness and equality in water management and, as a result, affects long-term sustainability. Through analysis of empirical data of communal small-scale irrigation systems in both countries, the article discusses who participates, how and why they participate, and the reasons for low numbers of women in leadership roles within the WUAs. Finally, the article reflects on possible enabling conditions that could foster inclusive participation, increase the quantity and capacity of women in management and leadership roles, and the benefits this may bring to sustainable irrigation systems.
