Analysis of the hydraulics of the irrigation canals of Otrar, Kazakhstan
Surveys of relic canals at the Oasis of Otrar in Kazakhstan have been used to re-construct patterns of agricultural water use for irrigation between AD700 and AD1500. Hydraulic simulation software was used to calculate the water carrying capacity of historical irrigation canal networks. An analysis of modern day irrigation systems has enabled the calibration of crop water use models and an ...

Watering Scarcity: Private investment opportunities in agricultural water use efficiency
This report was prepared by Rabobank in collaboration with the World Resources Institute. In many regions around the world, demand for fresh water now outstrips renewable supplies. Water scarcity is projected to worsen considerably due to a combination of factors such as population increase, higher incomes and changing lifestyles, pollution, and climate change. Agriculture is by far the biggest ...

The water we eat
Agriculture imposes a heavy and growing burden on Europe's water resources, threatening water shortages and damage to ecosystems. To achieve sustainable water use, farmers must be given the right price incentives, advice and assistance. Food is intrinsically bound to human wellbeing. Besides the importance of good food for good health and the pleasure we derive from eating, agricultural ...

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 ...

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 ...

Performance evaluation of condensation–irrigation solar system under arid climate conditions
Scarcity of water, major critical concern in arid areas, has led to the use of low–quality irrigation water in agriculture in most of arid climate areas. The quality of water used for agriculture has to be reduced to a sustainable level that is also adapted to the environment. This paper presents the performance of a pilot condensation irrigation (CI) solar system in Tunisia under arid ...

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). ...

Modeling Nitrogen and water management effects in a Wheat-Maize double-cropping system
Excessive N and water use in agriculture causes environmental degradation and can potentially jeopardize the sustainability of the system. A field study was conducted from 2000 to 2002 to study the effects of four N treatments (0, 100, 200, and 300 kg N ha–1 per crop) on a wheat (Triticum aestivum L.) and maize (Zea mays L.) double cropping system under 70 ± 15% field capacity in the North China ...

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 ...
