Giving way to the elephant: the dynamics of participation in the management of a Balinese subak
Irrigation Communities, a common reference point for Water Users' Associations, are corporate groups that manage irrigation systems under local or indigenous charters. This paper begins by pointing out that local control in irrigation does not necessarily imply effective participatory management. It then undertakes a detailed examination of the internal dynamics of participation in an Irrigation ...

Irrigation demand modelling using the UKCP09 weather generator: lessons learned
The determination of irrigation demand is typically based on crop modelling using a long historic record of local daily weather data. However, there are rarely adequate weather station records near to given sites; often any local records cover a limited number of years, are incomplete, costly or are of poor quality. This paper examines whether version 1 of the UKCP09 weather generator can ...

The effect of winter flood irrigation with saline water on groundwater in a typical irrigation area
Flood irrigation in the winter has been widely applied in northwest China for several years, but little attention has been paid to the flood irrigation program to date. In order to seek a reasonable irrigation quota, a flood irrigation experiment using two common quotas (1,800 and 1,200 m3 ha−1) was conducted in an area irrigated by saline water in the Nanjiang basin with shallow ...

Sustaining participation in irrigation systems of Ethiopia: what have we learned about water user associations?
Community participation, defined as engaging users of schemes in the decision-making processes for the planning and implementation of irrigation projects, is critical for the sustainability of irrigation schemes. This study was carried out in three regional states of Ethiopia to investigate the contribution of water user associations (WUAs) to sustaining participation in irrigation projects. ...

Egypt: The role of water users` associations in reforming irrigation
Egypt’s water resources are severely constrained. This calls for increasing the water use efficiency by improving irrigation management practice, as the agriculture sector is the main user of water resources. Much of the irrigation infrastructure is elderly and in need of rehabilitation. The irrigation improvement program (IIP) is one of the large-scale projects to help Egypt to sustain its ...

Raising water productivity
With water shortages emerging as a constraint on food production growth, the world needs an effort to raise water productivity similar to the one that nearly tripled land productivity during the last half of the twentieth century. Worldwide, average irrigation water productivity is now roughly 1 kilogram of grain per ton of water used. Since it takes 1,000 tons of water to produce 1 ton of grain, ...

Numerical simulation of bare soil water and heat flow under an automated irrigation system
Modern irrigation techniques use automated systems where irrigation schedules are controlled according to certain criteria. The objective of this study is to numerically estimate irrigation events, water content and temperature distributions, evaporation, drainage, and soil water under closed loop automated irrigation systems of a bare soil. The automated irrigation system is activated and ...

Subsurface drip and overhead irrigation: a comparison of plant boll distribution in upland cotton
Although subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops, the effects of SSD on the distribution of bolls on cotton plants (Gossypium hirsutum L.) have not been thoroughly examined. The purpose of this study was to add to the current knowledge about the effects of SSD on cotton yield dynamics. Cultivar DP 488 BG/RR was grown in three studies ...

Novel simulation-based algorithms for optimal open-loop and closed-loop scheduling of deficit irrigation systems
The scarcity of water compared with the abundance of land constitutes the main drawback within agricultural production. Besides the improvement of irrigation techniques a task of primary importance is solving the problem of intra-seasonal irrigation scheduling under limited seasonal water supply. An efficient scheduling algorithm has to take into account the crops' response to water stress at ...

Effects of treated municipal wastewater on fluctuation trend of leaf area index and quality of maize (
Zea mays )The effect of primary-treated municipal wastewater (TMWW) on the leaf area index (LAI) and quality of maize (Zea mays) was studied in comparison to the clean irrigation water (control). The experiment was based on a randomized block design with four replicates, and it was conducted in a field experiment in Aligoudarz (Iran). Irrigation was applied with five different methods as treatments: T1: ...

Ecohydrological modeling of irrigation scheduling of maize using time series analysis in the temperate region of Kashmir valley, India
Water, one of the most crucial inputs of irrigation, should be utilized judiciously to identify appropriate strategies for planning and management of irrigated farmland. The present study was conducted for the crop maize (Zea mays), grown mainly in the rabi-season (July–October), to evaluate the irrigation water requirements in the temperate region of Kashmir Valley, India during the ...

Irrigation planning for sustainable rain-fed agriculture in the drought-prone Bundelkhand region of Madhya Pradesh, India
The recent spells of recurrent and consecutive droughts in the Bundelkhand region in Central India have led to uncertain rain-fed agriculture and its sustainability. Adequate knowledge of starting dates and lengths of dry spells has a considerable importance in rain-fed agriculture, irrigation planning, and various decision-making processes. The long dry spells incur heavy costs to the affected ...

CSE algorithm: ‘canal survey estimation’ to evaluate the flow rate extractions and hydraulic state in irrigation canals
One of the main problems in water management of irrigation systems is the control of the equitable distribution of water among different orifice offtakes. The difficulty of managing a canal is partly caused by the lack of knowledge of the canal state because the scheduled demand is often not fulfilled, since farmers extract more water than is scheduled and it is impossible for the watermaster ...

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 ...
