Enhancing and utilising landscape heterogeneity to meet multiple land use objectives

The broad aim of the project was to provide land managers with information that will encourage them to further value, protect and enhance vegetation diversity by demonstrating the practical benefits that can be derived from this natural asset in Australian rangelands. Vegetation diversity and local climate influences combine to produce differences between regions in the patterns of plant growth from year to year, such that the timing of droughts and favourable years can vary between regions. We set out (more)...

Changing Irrigation Systems and Management in the Harvey Irrigation Area

Milestone Report - End of Stage 1 - February 2004

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)...

Improving the water use efficiency of horticultural crops

NPIRD project CDH1

The results of this project show that there is considerable scope for improving the water use efficiency of fruit production in Australia. The two year project has sought to test the partial rootzone drying (PRD) irrigation method, originally developed for grapevines, in a range of woody perennial horticultural crops. The technique requires that both wet and dry rootzones are simultaneously created. Results with grapes, citrus and pears have given exciting results. (more)...

Irrigation Insights 5 - Water Use Efficiency: an information package

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 (more)...
