Impact of irrigation water scarcity on rural household food security and income in Pakistan
As Pakistan is currently facing a severe shortage of irrigation water, this paper analyzes the determinants of water scarcity and its impact on the yield of cereal crops (wheat, maize and rice), household income, food security and poverty levels by employing the propensity-score-matching approach. This study is based on a comprehensive set of cross-sectional data collected from 950 farmers ...

Sustainable Management of Large Scale Irrigation Systems: A Decision Support Model for Gediz Basin, Turkey
While water on a global scale is plentiful, 97% of it is saline and 2.25% is trapped in glaciers and ice, leaving only 0.75% available in freshwater aquifers, rivers and lakes. About 70% of this fresh water is used for agricultural production, 22% for industrial purposes and 8% for domestic purposes. Increasing competition for water for domestic and industrial purposes is likely to reduce the ...

Performance Evaluation of Selected Soil Moisture Sensors
Abstract Irrigation water management practices could greatly benefit from using soil moisture sensors that accurately measure soil water content or potential. Therefore, an assessment on soil moisture sensor reading accuracy is important. In this study, a performance evaluation of selected sensor calibration was performed considering factory- laboratory- and field-based calibrations. The selected ...

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 ...

Implementing participatory irrigation management in Thailand
Participatory Irrigation Management (PIM) was formally adopted in Thailand in 2004. The involvement of farmers in water management decision making is necessary to meet the implementation challenges of this initiative. As such, the research presented in this paper considered the level of farmer involvement in water management and decision making, and the lessons learned by both government ...

Institutional analysis of irrigation management in Haiti: a case study of three farmer managed schemes
In the late 1990s, like many other developing countries, Haiti started a process of devolving responsibilities over irrigation scheme management to water users’ associations. In this paper, a three-step methodology for institutional analysis is applied to investigate the functioning of this new setting in Haiti, using three irrigation schemes managed by farmers as case studies. First, the ...

Turkey: Transfer of irrigation management to water users associations
Up to the early 1980s, operations and maintenance for irrigation systems was highly centralised, but this was imposing an increasing institutional and financial burden on the government. Contributing factors were: very low ratio of billing and collection rates or no collection at all; very high water consumption, even wastage; no cost recovery for investment; and no local interest by the farmers ...

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 ...

Irrigation challenges in the sub-humid US Mid-South
Irrigated area in the Mid-South USA continues to increase and now totals four million ha. Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies ...

Validating the FAO aquaCrop model for irrigated and water deficient field maize
Accurate crop development models are important tools in evaluating the effects of water deficits on crop yield or productivity. The FAO AquaCrop model predicts crop productivity, water requirement, and water use efficiency (WUE) under water-limiting conditions. A set of conservative parameters [calibrated and validated for maize (Zea mays L.) in a prior study and considered applicable to a wide ...

Unlocking Precision and Sustainability with Portable Soil EC Detectors
For millennia, farmers have tilled the land, guided by intuition and tradition. But beneath the surface, in the hidden realm of the soil, lies a powerful language waiting to be deciphered. A language not of words, but of electrical whispers, dictating the very foundation of plant growth and ecosystem health. This language is spoken in terms of Electrical Conductivity (EC), and to understand it, ...

Using Soil Water Sensors to Improve Irrigation Management
Abstract Irrigation water management has to do with the appropriate application of water to soils, in terms of amounts, rates, and timing to satisfy crop water demands while protecting the soil and water resources from degradation. In this regard, sensors can be used to monitor the soil water status; and some can be used to calculate irrigation amounts and to decide when to optimally irrigate. ...

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 ...

The Arkansas irrigation yield contest
Most farmers are familiar with contests in which participants try to achieve the maximum yield of a crop from a given field. Fewer would be familiar with a contest in which participants’ total crop yield is divided by the amount of water they use—thus measuring their water use efficiency. That’s the kind of contest that Dr. Chris Henry and his colleagues at the University of ...

How cooling irrigation systems benefit orchards
Typical Challenges in Orchards Managing an orchard comes with several challenges. Pest and disease control is a constant battle to protect trees and ensure high-quality fruit. Weather fluctuations, including extreme temperatures and storms, can harm tree health and productivity. Adequate water management, by balancing irrigation and drainage, is crucial for optimal growth. Nutrient management ...

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 ...
