Agroforestry: Water Use Efficiency
2020Agroforestry is the intentional integration of trees and shrubs into agricultural systems. In agricultural systems, water is often the major factor limiting growth. When water availability is limited as a result of limited supply or high cost, its efficient use becomes critical to successful production systems.

The loss of water vapour from aerial tissues of terrestrial plants as they assimilate CO 2 from the atmosphere for photosynthesis is biophysically unavoidable. Photosynthesis and transpiration co-vary with the aperture and density of stomatal pores, and are co-determined by the leaf area, which is involved in light capture and water loss.

Increasing Water Use and Water Use Efficiency in Dryland Wheat
Agronomy Journal, 2001Water use efficiency (WUE), the ratio of grain yield to crop water use, provides a simple means of assessing whether yield is limited by water supply or other factors. Based on this assessment, yields of commercial dryland wheat (Triticum aestivum L.) crops in southeastern Australia are usually not limited by water.

Journal AWWA, 1996
A disturbing trend threatens to return the role of water conservation to that of bygone days, when it was regarded merely as a means to cope with temporary water shortages such as droughts. Water utilities across the United States, and particularly in California, are facing pressures to sell more water to increase revenues.

Genetic Engineering as a Key to Water-Use Efficiency
Agricultural Meteorology, 1974Abstract Most of the present breeding systems are locked into certain germ plasm sources and the chance development of cultivars with greater water-use efficiency is very small. Extensive germ plasm pools containing genes for greater water-use efficiency exist, but heavy selection pressure is necessary to identify these genes.

Smart irrigation technology for efficient water use
Proceedings of the 7th International Conference on Software Engineering and New Technologies, 2018The importance of water resource does not need to be proven. At first sight water seems to be the most abundant resource on earth, but in fact freshwater represents only 1% of all terrestrial water, and the remaining 99% are not available for human use.Of all economic sectors, irrigation is the sector where water scarcity has the greatest impact ...

Water use efficiency by the olive.
2008AbstractThe olive tree is very efficient in its use of water. It requires 312 g water to produce 1 g dry matter, whereas other evergreen plants such as Citrus and Prunus species require 400 and 500 g, respectively. Water consumption by the olive is 30 and 40% of that of Citrus and Prunus species, respectively.

Water Use Efficiency as a Method for Predicting Water Use by Weeds
Weed Technology, 1996Water use by weeds is one type of loss that contributes to the cost of weeds to agriculture. Water use efficiency provides a mechanism by which water use by weeds can be estimated. Uncontrolled weed growth could result in estimated irrigation costs exceeding $50.00/ha. Weeds like barnyardgrass at threshold densities in irrigated crops like sugarbeet or
