Water use efficiency Water-use efficiency (WUE) can be defined as the economic value added per volume of water withdrawn, by an activity. Examples of economic activities include agriculture, fishing, forestry, mining, quarrying, manufacturing, constructions and energy. Agriculture, industry, municipal...
However, the expected water saving by the improved agricultural water use efficiency may be offset by the rebound effect, which means the goal of water saving by improving agricultural water use efficiency is not achieved. Based on the definition of the rebound effect of agricultural water use, ...
ndenotes the shape parameter of soil water retention curves74,ψ50denotes xylem water potential at 50% loss in xylem conductivity, andg1denotes stomatal conductance slope parameter from ref.78, which is inversely proportional to the square root of water use efficiency. For description and data ...
Not only would this be a fiscal plus for the MUD that will pay the energy bills, since it takes water to make energy – the so-called water-energy nexus – all this energy conservation would enhance the overall efficiency of the region-wide water system. Fourth, under the surface water ...
Even though irrigation efficiency is a term widely used by plant physiologists, agronomists, irrigation engineers, and economists, both the definition and the perspectives of the term vary with the different disciplines. This review presents and compares irrigation water use efficiency from the ...
Water-Use Efficiency Under Changing Climatic Conditions Amitav Bhattacharya, in Changing Climate and Resource Use Efficiency in Plants, 2019 3.13.5 Leaf Temperature and Vapor Pressure Deficit Water loss by transpiration is not only affected by the conductivity of the stomata, but also by the driving...
The presentation of raw water and worked water use efficiency as percentages has also been inconsistent historically. The recommended definition of water reuse efficiency by current reporting standards is worked water use divided by total water use (raw + worked). Whereas, historically several mining ...
This places an additional demand for efficiency in planning for the future. In developing regions, the shortage of financial and technical resources further add to the need for their well-judged, efficient use in a long-term perspective. With the current lack of planning and...
On the other hand, CO2 fertilization may enhance leaf area, which could cancel the water-saving from increased water use efficiency36,37. Although the leaf- to ecosystem-level increases of water-use efficiency and leaf area under higher CO2 have been well-studied with laboratory and field ...
(over 30-years) changes in tree-ring δ13C-derived intrinsic water-use efficiency (iWUE), δ18O and δ15N for four species in twelve forests across climate and atmospheric deposition gradients in Britain. The increase in iWUE was not uniform across sites and species-specific underlying ...
