We calculated parameters related to leaf photosynthesis and water-use efficiency from stable carbon isotope ratios (13 C/ 12 C) of whole leaves.

Because of these policies, production increased by $353 million, while water-use efficiency was also drastically improved.

Environment Canada is "cutting several water-related programs and others will be cut severely, including some aimed at promoting or monitoring water-use efficiency (May 2012)."

These employ physiological and anatomical adaptations to increase water-use efficiency and allow increased primary production to take place under conditions that would normally limit carbon fixation by C3 plants (the majority of plant species).

Smart Irrigation Month is a campaign by the Irrigation Association to increase public awareness of the value of water-use efficiency and grow demand for water-saving products, practices and services.

Basic physiological investigation of these gas exchange processes has yielded valuable carbon isotope based methods that are used for breeding wheat varieties with improved water-use efficiency.

The Southern California World Water Forum-SoCal WWF promotes regional water-use efficiency and conservation in addition to sustainable potable water and sanitation projects for developing world communities.

With regard to water-use efficiency, Plant X was designed to be a "zero-discharge facility," which means no process waters are directly discharged from the plant site.

Directs the Secretary to allocate annually funds to States of the High Plains Region for research in water-use efficiency, cultural methods, irrigation technologies, water-efficient crops, and water and soil conservation.

Improvements in water-use efficiency are possible in every sector.
