Morocco: Irrigation water pricing policy of large scale irrigation projects
In Morocco, the consequence of increased industrialization and a rapidly growing population accentuated by a progressive shift from rural to urban living. This resulted in the growth of requirements for the quality and quantity of water resources, their more intensive and comprehensive use. The government policy in the agricultural sector has always favored investments in the irrigation ...

An analysis of groundwater irrigation expansion in India
This paper suggest that groundwater irrigation expansion in India is driven mainly by the population pressure and not necessarily dependent on the change in surface water irrigation. However, in the districts irrigated by Groundwater only, our findings indicate that the marginal effect of groundwater on Gross Irrigated Area (GIA) is lower than that in the district endowed with both surface and ...

Assessing the regional food insecurity in Bangladesh due to irrigation water shortage in the Teesta catchment area
Bangladesh is losing huge food production from the Teesta catchment area due to a lack of availability of irrigation water in the dry and lean period because of unilateral water withdrawal in the upstream country, India. The area, which is directly dependent on the irrigation water of the Teesta river, is the study area for this paper. The study reveals that rice production in Dalia, ...

Performance evaluation of irrigation network using fuzzy multicriterion group decision making technique
Present paper discusses applicability of fuzzy multicriterion decision making (MCDM) technique, namely, interval valued fuzzy TOPSIS (IVFT) for selection of suitable irrigation subsystems among 30 such subsystems of Khadakwasla Irrigation Project, India. Five performance evaluations related criterion, namely, participation and cooperation, effective water availability, conjunctive use, economic ...

Assessment of climate change impacts on irrigation water requirement and rice yield for Ngamoeyeik Irrigation Project in Myanmar
This study analyzes the impacts of climate change on irrigation water requirement (IWR) and yield for rainfed rice and irrigated paddy, respectively, at Ngamoeyeik Irrigation Project in Myanmar. Climate projections from two General Circulation Models, namely ECHAM5 and HadCM3 were derived for the 2020s, 2050s, and 2080s. The climate variables were downscaled to basin level by using the ...

Water Irrigation Conservation
Poly-Fastener water conservation systems help promote water conservation and irrigation projects in drought-stricken areas around the globe. This unique, low-cost system offers long-term solutions to food production problems in arid regions, an urgent need among many third world nations. While the concept is not new, low-cost technology offering the same effective function of more expensive ...

HDPE Canal Liner for Irrigation Water Project in China
HDPE canal liner is the widely used geomembrane liner products and the essential lining system for the efficient use of water resources due to their features of lowest permeability, excellent anti-seepage and ultra stress crack capacity, etc. More than 45% of water used in the agriculture would be lost due to seepage. HDPE canal liner is an affordable solution to prevent water loss of ...

Farm Dam Liners for Irrigation Dam Project in Kenya - Case Study
Farm dam liners are the kind of HDPE geomembrane liner which is the cost effective solution to prevent water leakage when you build a irrigation pond for crops, support aquaculture, or provide water for livestock. The thickness of farm dam liners should be determined according to the bearing water pressure. For the water head below 30m, the unreinforced polymer plastic dam linings can be ...

Irrigating with reclaimed water through permanent subsurface drip irrigation systems
ABSTRACT In Hawaii, reclaimed water has been used in agricultural irrigation and the irrigation of golf courses and other large landscaped areas. However, the Hawaii Department of Health's new "Guidelines for the Treatment and Use of Reclaimed Water" published in November 1993, limits uses of reclaimed water through overhead sprinkler irrigation systems. The subsurface drip irrigation concept ...

Irrigation and Nitrogen Best Management Practices Under Drip Irrigated Vegetable Production
Abstract Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several ...

Seasonal ammonia losses from spray-irrigation with secondary-treated recycled water
This work examines ammonia volatilization associated with agricultural irrigation employing recycled water. Effluent from a secondary wastewater treatment plant was applied using a center pivot irrigation system on a 12 ha agricultural site in Palmdale, California. Irrigation water was captured in shallow pans and ammonia concentrations were quantified in four seasonal events. The average ammonia ...

Subsurface drip irrigation; the future of Irrigation is Underground
Placing water beneath the soil surface via buried lines is slowly becoming the "preferred choice" of many vineyard irrigators. The reasons are many, including the absence of surface evaporation, as well as reduced weed growth, herbicide washout, maintenance, injury, and vandalism found with using conventional water application systems. The advantages of subsurface drip add to reduced cost for ...

Watertronics Dee river ranch case study
The Future of Irrigated Agriculture Lindsay’s complete solution from pump to pivot Summary The 10,000-acre Dee River Ranch near Aliceville, Alabama, is an example of the future of farming on display today. Owned by Annie Dee, her brother Mike Dee, and their 10 brothers and sisters, Dee River Ranch is located near the Mississippi-Alabama state line. The business is made up of a successful ...

Soil Water Sensors for Agriculture – Theory and Issues
Soil water sensors have been used for irrigation and water management in agriculture for many years, but with limited success in many cases. Nonetheless, the use of soil water sensors in increasing as water scarcity increases and, conversely, problems associated with over irrigation also increase. Common problems with soil water sensing included sensor failure, problems with wiring, lack of or ...

Water reuse through subsurface drip irrigation systems
Water reuse in Hawaii has been primarily relegated to agricultural irrigation and irrigation of golf courses and other large landscaped areas. The continuing effort to conserve and preserve potable water resources emphasizes using alternative water sources for irrigation. Agriculture, golf courses, highways, parks, playgrounds and cemeteries are among the heaviest users of irrigation water due to ...

Subsurface Drip Irrigation (SDI) on Turfgrass: A University Experience
ABSTRACT The practice of placing tubing and drip emitters beneath the soil surface to irrigate crops continues to gain acceptance in agriculture, particularly in the production of annual crops. However, the use of the subsurface drip method to irrigate turfgrass has only begun to be explored. This paper focuses on the experiences gained at California State University, Fresno (CSUF) in adopting ...

Delta Drainage and Irrigation System - Case Study
Background Delta, British Columbia is located in the Fraser River delta on the shores of the Pacific Ocean, just south of the City of Vancouver. Delta comprises mostly agricultural land, with typical ground elevations near sea level. Levees protect the area from potential floods from the Fraser River and tidal surges from the Pacific Ocean. Of the 13,500 hectares (ha) watershed, 6,300 ha is ...
