Indigenous Interests in Tropical Rivers: Research & Management Issues

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)...

Detection of Pinus radiata wildlings in remnant vegetation in the lower SE of South Australia, and far SW of Victoria

This investigation attempted to use fine spatial scale Quickbird imagery and digitised aerial photography to indicate the location of pine wildlings within a selection of vegetation communities.

Optimising management of core mesquite infestations in Australia

We conducted a three-year field study to test whether the invasiveness of mesquite, and its response to biological control, differs with taxa and climate (between region and years). Permanent study sites were set up and monitored in the core infestations

The Significance of Night Time Evaporation from Irrigation Farm Dams Across Australia

This report documents the numerical analysis performed for the Land and Water Australia (LWA) National Program for Sustainable Irrigation project “The significance of night time evaporation from irrigation farm dams” under contract UWA45.The objective of the present study is to further develop the numerical model DYRESM to make it applicable to irrigation farm dams and to subsequently apply it to gain insights into (more)...

Scoping Study: Improving plants' water use efficiency and potential impacts from soil structure change - research investment opp

The key questions addressed by this scoping study are:

• What understanding, techniques and tools require further explanation or development to improve water use efficiency?
• How well do we understand the impacts of long-term irrigation on soil structure? What are the effects of soil structure change (within and around the root zone on the flow of water and rate of movement along various pathways of salts?

Scoping Study: Common Hydrological Features in Australian Irrigation Areas

This scoping project investigated the following two questions:

• What is the best way to present material on the common hydro-geological systems where irrigation areas are situated.
• Which hydro-geological systems should be represented?
  

Scoping Study: Soil-water and salt movement associated with precision irrigation systems - research investment opportunities

The Board of the National Program for Sustainable Irrigation commissioned this scoping document to assist in its research investment deliberations. The key question addressed by this scoping study is: What has to be developed or modified to understand and monitor the three dimensional flow of water and salt movement in: (a) the root zone when precision irrigation systems are used, and (b) the soil profile, assuming that we are able to manage the preferred salt storage zones? (more)...

Scoping Study: Reduction of evaporation from farm dams

Evaporation reduction from farm dams in Australia is regarded as one of the few areas where there are real water savings to be made. At this stage, there are a number of commercial evaporation reduction systems available that use either a hard or polymer cover. Currently these systems are deemed to be viable (M. Durack pers. comm., 2004) for high value crops such as table grapes but are generally not financially viable for lower value crops such as sorghum or cotton. The Department of Natural Resources (more)...

Sustainable Irrigation/ANCID Travel Fellowship

Objectives

• To provide professionals within the irrigation industry the opportunity to travel overseas to gain experience and knowledge in their nominated area of interest
• To report the travel fellowship winners travel and study program in newsletters for the various irrigation programs and associations and to disseminate the outcomes and learnings of the fellowship broadly
