Irrigation - Water Management, Pollution and Alternative Strategies
Irrigated agriculture is the most significant user of fresh water in the world and, due to the large area occupied, is one of the major pollution sources for the water resources. This book comprises 12 chapters that cover different issues and problematics of irrigated agriculture: from water use in different irrigated systems to pollution generated by irrigated agriculture. Moreover, the book ...

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 ...

Reuse: Agriculture
Agronomic and water quality considerations Water use for agricultural irrigation is the largest component of water use in most countries and is more than 70% of human water use in drier countries. Use of recycled water for irrigation requires consideration of soil types, groundwater levels, soil and water chemistry, nutrient loads, limits on chemicals, the salt tolerance of crops, the ...

Achieving financial sustainability and recovering costs in bank financed water supply and sanitation and irrigation projects
This note is a partial response to the above mentioned 2010 Independent Evaluation Group (IEG) evaluation. It covers the specific issues to be addressed in the Water supply and Sanitation (WSS) sector and in the irrigation sector in two distinct parts, because if WSS and irrigation have some common features, there are many distinctions to be made. Among the various water-using sectors, that ...

Wastewater retreatment and reuse system for agricultural irrigation in rural villages
Climate changes and continuous population growth increase water demands that will not be met by traditional water resources, like surface and ground water. To handle increased water demand, treated municipal wastewater is offered to farmers for agricultural irrigation. This study aimed to enhance the effluent quality from worn-out sewage treatment facilities in rural villages, retreat effluent ...

Agriculture and economics in the Water Framework Directive: progress and limitations
Agriculture is having an increasing impact on water resources in Spain, both from a quantitative (consumption) and qualitative (pollution) perspective. Therefore, the implementation of the Water Framework Directive (WFD) will have a great impact on this sector. In fact, new river management plans aim to reduce these pressures through the implementation of programmes of measures. These instruments ...

Five benefits of agricultural smart irrigation
Population growth and an increase in irrigated agricultural land lead to a greater need for water and energy, at a time when global warming and rising greenhouse gas emissions are posing a real environmental challenge. In this context, the benefits of smart irrigation, i.e., using the exact amount of water needed for each crop, help to optimize this scarce resource. If we take a closer look at ...

Water efficiency of agricultural production in China: regional comparison from 1999 to 2002
We apply stochastic frontier analysis (SFA) techniques to a provincial level data set to measure technical and water efficiency in China's agricultural production from 1999 to 2002. The determinants of the efficiencies are identified together with the physical determinant structure of the irrigation factor, which refers to the water use per irrigated land area. The study yields the following ...

Opportunities for saving and reallocating agricultural water to alleviate water scarcity
As water scarcity worsens globally, there is growing interest in finding ways to reduce water consumption, and for reallocating water savings to other uses including environmental restoration. Because irrigated agriculture is responsible for more than 90% of all consumptive water use in water-scarce regions, much attention is being focused on opportunities to save water on irrigated farms. At ...

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 ...

Improved Agricultural Irrigation Scheduling Using a Soil Water Content Sensor - Case Study
Abstract The key to scheduling irrigation timing and amounts is determining moisture depletion in the soil. Two common methods include tracking crop evapotranspiration (ETc) and tracking the water content with a sensor buried in the soil. In Colorado, a popular online tool that estimates the ETc for a variety of well-irrigated crops is the Colorado Agricultural Meteorological Network (CoAgMet). ...

Self-Cleaning Irrigation Water Filters
One of the critical components of successful agriculture is irrigation, which ensures that crops receive the water they need to thrive. However, using untreated or impure water for irrigation can have detrimental effects on crops and the environment. Self-cleaning irrigation water filters have emerged as a groundbreaking solution to this problem. The Importance of Self-Cleaning Irrigation Water ...

Food and water insecurity: re-assessing the value of rainfed agriculture
ABSTRACTRainfed agriculture has potential to produce needed cereals for the growing populations of West and Central Asia even though rainfed agriculture is perceived as risky. The value of rainfed agriculture to produce competitively should be re-assessed. This requires the concerted efforts of farmers, researchers, and policy makers to work on the technical factors that determine agricultural ...

Irrigation Systems 101: What you need to know
In the perfect scenario everyone could rely on rainwater for their farming practices, but this is not always the case. This is why employing the right choice from the different irrigation systems available is crucial for agricultural success. Irrigation systems are basically an artificial way to provide water to fertile soil for agricultural purposes. Crop irrigation is necessary to overcome ...

Discerning shifting irrigation practices from passive microwave radiometry over Punjab and Haryana
Overexploitation of groundwater (GW) in the recent past is a well-known fact for the Punjab and Haryana region of India, as reported by several studies using satellite-based gravity anomaly from the Gravity Recovery and Climate Experiment mission and also by using observed data. This decline in GW has enforced the Punjab Preservation of Sub-Soil Water Act 2009, and resulted in change in rice ...

Irrigation water governance in practice: the case of the Canale Emiliano Romagnolo district, Italy
Irrigation is an essential element of agricultural production whose absence would create great economic hardship in many regions of the global South. Yet irrigated agriculture uses 70% of global fresh water withdrawals, putting major pressure on global water resources. Whilst much research has focused on technological solutions to improve irrigation efficiency, irrigation water ...

Tunisia: Reform of irrigation policy and water conservation
An arid country with limited water resources, Tunisia depends heavily on irrigated agriculture. The sector contributes 30-40% of the value of agricultural production, and is highly important in some regions. However, abstraction for irrigation accounts for 83% of the available water resources, competing with other uses. To conserve water resources and encourage demand management in the irrigation ...
