Abstract:
This publication forms part of the National Program for Sustainable Irrigation Irrigation Insights series. It explores some of the many facets of the term water use efficiency, and attempts to provide a simple, clear and concise guide to the topic. It also collates and summarises some of the current scientific and field knowledge, though with a rather 'Australia-centric' flavour. The publication was written to a brief that required the production of a compendium of current knowledge on water use efficiency that: *provides an explanation of and context for water use efficiency at a range of scales *reviews and assesses procedures for estimating water use efficiency *presents case studies and examples of water use efficiency estimation at a range of scales * reviews the current status of water use efficiency research and development. It is intended to appeal to a wide audience, from water users, through to academics, service sector, agencies and technocrats and, as such, is a practical, rather than theoretical, guide
