Knowledge is a cornerstone of irrigation management

The importance of research was highlighted in a recent speech by the National Water Commission Chair, Chloe Munro, who stated: “One of the cornerstones of improved water management is better knowledge, science and information. There has been significant investment in these areas, particularly through the programs that were funded as part of the National Water Initiative implementation package. Despite this, the gaps are considerable and the need for new (more)...

Changing Irrigation Systems and Management in the Harvey Irrigation Area

Project DAW45 was conducted over the Harvey irrigation seasons 2003-04 and 2004-05. Seasons in Harvey are relatively consistent extending usually from October to May.

The project was conducted in two stages to ensure adequate consideration of the issues and planning for the case study, along with integration with other related research work, prior to the commencement of the case study.

Knowledge & tools to manage fertigation technologies in highly productive citrus orchards for minimal environmental footprint

High frequency fertigation is being adopted by Australian citrus producers as an alternative to traditional approaches to supplying water and mineral nutrients to trees. Information, guidelines and practical tools to assess performance are insufficient to support the economic & sustainable use of these technologies for citrus production on Australian soils.

Long term sustainability of precision irrigation

There is now strong evidence of serious soil structural decline under precision irrigation, but practical tools to identify the conditions for this degradation are not yet available. We will identify a range of paired (precision-irrigated / non-irrigated) texture-contrast soils in vineyards across the Barossa Valley and assess the impact of this irrigation on soil properties important for root growth and water uptake.

Putting Plans into Practice, Environmental Water Allocation R&D Program

The degradation of Australia’s wetlands has brought into sharp focus the need to manage factors such as altered flow and water regimes. Exchanging knowledge between wetland managers and wetland scientists and putting it into practice is an essential part of this management. Yet environmental watering of wetlands is a relatively new type of intervention, especially where engineering infrastructure is used. It is largely restricted to south eastern Australia. Thus, while there is considerable (more)...

Indigenous Interests in Tropical Rivers: Research & Management Issues

A Scoping study for Land & Water Australia's Tropical Rivers Program

This report outlines a number of priority areas of research interest arising from the literature reviewed and the interviews of representatives or nominees from Indigenous organisations. They fall under two major themes: The need for a sound understanding of the current condition of river and wetland environments and their contemporary role in meeting the subsistence and spiritual needs of Indigenous communities. Increased pressure on resources, places, and sites is felt by many groups (more)...

National Riparian Lands Research & Development - Phase Two

A review of the Riparian Lands R&D Program Phase Two was conducted in 2004 and found that the standard of the science was very high and was highly relevant to the management of riparian zones. The program had maintained a strong publication record and had a high level of ability to communicate to a wide range of audiences. The review reported that the Riparian Lands Program had a high profile and had a substantial potential to influence river management, planning, investigation and policy. The program (more)...

National Riparian Lands Research Development - Phase One

Phase 1 of the Program ran for nearly 7 years in total. It had 3 sub-programs, two based on scientific experimentation and one on practical application through a series of demonstration projects. Phase 1 had funding of $4.6m from Land & Water Australia, $0.7m from third parties (mainly State agencies) and $2.3m from research organisations. It was guided by an advisory committee with representation from Commonwealth, State and Territory agencies. This group played an (more)...
