Irrigation Innovation in a Changing Climate Workshop Report

The aim of the workshop was to kick off a process to develop a ten-year irrigation innovation strategy. The workshop, held in Canberra on 16 September 2008, attracted about 100 participants from a broad cross-section of the irrigation industry. It included people from urban water organisations, garden irrigation supply companies, irrigators, policy makers, researchers, manufacturers and rural water supply organisations.

Changing Irrigation Systems and Management in the Harvey Irrigation Area

The project is examining issues of water use efficiency (WUE) in the South West Irrigation Area (hereafter called the Harvey Irrigation Area). A significant WUE issue is whether water savings, improved pasture yields and farm productivity can be achieved through sprinkler (centre pivot) irrigation of dairy pasture in comparison with traditional surface bay irrigation (often called flood irrigation). This project is a case study conducted on (more)...

Determining a Framework, Terms and Definitions for Water Use Efficiency in Irrigation

This report outlines the results of a consultancy to “Determine a Framework, Terms and Definitions for Water Use Efficiency in Irrigation”.

An issues paper was prepared in May, 1999 outlining the background, a simple framework, possible definitions for water use efficiency, examples of the most recent definitions of irrigation efficiencies and other issues considered relevant.

Improving water use efficiency by reducing groundwater recharge under irrigated pastures

Approximately 65% of water extracted for irrigation in Northern Victoria and over 30% in the NSW Murray Valley is applied to pastures. In 1996, Murray Irrigation Limited (MIL) introduced a Total Farm Water Balance Policy which aimed to limit farm water use to sustainable levels and hence to reduce groundwater recharge to the district watertable. The dairy industry had some concerns with the original limit of 4 Ml per hectare and initiated discussions (more)...
