Improving alfalfa irrigation in The west
Alfalfa grown for forage is a major crop in many areas of the western United States. In the arid and semi–arid west, irrigation is required to obtain economic alfalfa yields. Because alfalfa is a perennial crop with a potentially long growing season, it can use a substantial amount of water. Alfalfa production in Imperial County, CA, has been valued at more than $170 million dollars for ...

Impact of agricultural water reallocation on crop yield and revenue: a case study in China
Our study area in the People's Victory Canal Irrigation District of Henan Province in China has been transferring agricultural water to the city for municipal use. This study starts with an examination of the impacts of irrigation frequency, irrigation water sources, and irrigation water supply performance on crop yield and net crop revenue, using data from a survey of 182 households in the ...

Changes in water demands under adaptation actions to climate change in an irrigation district
Climate change will affect the water balance of irrigated agriculture. Therefore, farmers and irrigation managers should consider adapting to new scenarios. Changes in water demands in a Mexican irrigation district were studied using an irrigation-scheduling model. The impact on water demands of two potential adaptation actions, adjusting planting season and using longer-season varieties ...

Characterization of controlling hydrogeochemical processes using factor analysis in Puyang Yellow River irrigation district (China)
Groundwater chemistry is diverse and complicated and is regulated by both natural hydrogeochemical and anthropogenic processes. Determining the governing processes and their influence on groundwater chemistry is very important to understand groundwater quality evolution and establish reasonable water management strategies. Main cations (Ca2+, Mg2+, Na+, K+, and Sr2+), anions (Cl−, SO2−4, ...

A computer model to estimate seepage rates from automated irrigation distribution channels during periods of shutdown
Within the last 10 years throughout south-eastern Australia, there has been a rapid expansion of modernisation efforts by irrigation companies that has included installation of automatic control structures, the so-called total channel control (TCC) technology. TCC includes supervisory control and data acquisition technology, which results in production of integrated databases utilising real ...

Water allocation reform to meet environmental uses while sustaining irrigation: a case study of the Murray–Darling Basin, Australia
Governments are developing policy to reallocate water to environmental uses in many of the world's major river basins developed for irrigation. These policies can place considerable pressure on the irrigation sector to adjust, and may be perceived to conflict with food security and rural development goals. This paper reviews the literature examining opportunities to reduce irrigation ...

Irrigation water pricing policy for water demand and environmental management: a case study in the Weihe River basin
Irrigated agricultural production is the backbone of the Chinese agricultural sector, but the increasing demand for irrigation water, its inefficient utilization and overuse of chemical inputs, accompanied by the short supply of water resources have endangered the nation's agricultural and environmental sustainability. The Chinese government has proposed a water pricing policy with the ...

Stochastic order-based optimal design of a surface reservoir–irrigation district system
This paper explores the effects of streamflow uncertainty and the type of stochastic order, which is used for comparing stochastic variables, on optimal design of a reservoir multi-crop irrigation district system. Four nonlinear mathematical programs with an economic objective function including deterministic, stochastic-EXP with expected value order, stochastic-SD with stochastic dominance ...

Estimating water use efficiencies for water management reform in Southern Alberta irrigated agriculture
Water use technical efficiency (WUTE) and three definitions of water use economic efficiency (WUEE) were estimated for the four river sub-basins that encompass the 13 irrigation districts in Southern Alberta over a 5-year period: 2004–08. The average level of WUTE varied from 3.5 to 6.2 Mt dam−3. The gross economic value of crop production varied from Canadian (C)$345 to ...

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 ...

Extracting physical homogeneous regions out of irrigation networks using fuzzy clustering method: a case study for the Ghazvin canal irrigation network
Improving the current operation and maintenance activities is one of the main steps in achieving higher performance of irrigation networks. Improving the irrigation network management, influenced by different spatial and temporal parameters, is confronted with special difficulties. One of the controversial issues often faced by decision-makers is how to cope with the spatial diversity of ...
