National Program for Sustainable Irrigation Fact sheet 2005/1 Australian studies show an average of 30% of applied irrigation water passes through the root zone without being used by the crops it is intended to sustain. This water either becomes groundwater recharge or is intercepted by drainage networks and contributes to waterway pollution. Subsurface drip irrigation has shown great potential for increasing crop yield and uniformity, while decreasing water use and environmental impact. Importantly, subsurface irrigation applies water directly to the

National Program for Sustainable Irrigation Fact sheet 2005/2 The partial rootzone drying (PRD) method of irrigation, originally developed for grapevines, is now being used in a range of perennial tree crops in Australia and achieving some exciting results in citrus and pears, as well as grapes. The technique requires that wet and dry rootzones are created simultaneously around each plant.

The National Program for Irrigation R&D is the only national body to coordinate irrigation research activity in Australia. At present it is in its third 3-year funding phase, which is due to finish in June 2002. To get feedback from the irrigation industry about what shape irrigation research and development should take in the future and what the important issues will be, the program is running six workshops around Australia in October and November. Locations of these workshops are:

The National Program for Sustainable Irrigation's mission is to provide Australia with leadership through collaborative investment in research and innovation to achieve sustainable irrigation. It aims to achieve this mission by defining, commissioning and managing research projects that produce new information of national importance and facilitate its adoption.

Details about the second phase of the National Program for Sustainable Irrigation. The National Program for Sustainable Irrigation provides Australia with leadership through collaborative investment in research and innovation to achieve sustainable irrigation. Phase 1 of the Program was established in 2002 and built upon and extended the work of the National Program for Irrigation Research and Development. The Program offers a unique service - providing leadership to identify,
