The effect of changing irrigation strategies on biodiversity

The irrigation industry is facing substantial change that is likely to affect the quantity and timing of water supply, as well as the infrastructure involved in water delivery and use.
Managing these changes without further compromising environmental sustainability requires knowledge of how irrigation practices effect local and regional biodiversity, and the implications for biodiversity persistence of possible changes in policies, district water management and farming methods. This project (more)…

The Significance of Night Time Evaporation from Irrigation Farm Dams

Evaporation is a significant loss component from irrigation dams, and although numerous evaporation reduction methodologies exist, their adoption is hindered since they are deemed uneconomical. Any cost/benefit analyses that are done are generally based on poor evaporation estimates due to the complexities involved in evaporation prediction.
One area of uncertainty is the significance of night time evaporation. Similarly, the role of windsheltering on evaporation can be significant but is (more)…

Tri-State Project - Impact of Salinity on Horticulture in the Lower Murray

The project, started in November 2003 and to finish in early 2007, is split into two stages and deliverables are spread over agreed milestones.
Stage 1: Specific tasks and main deliverables for Stage 1 are:

A detailed literature review of the salinity relationships for the commonly grown crops (grape, citrus, stone fruit, melon and vegetables) in the Lower Murray region;
Identify the knowledge gap in salinity relationships;
Explore the salinity (more)…

Understanding and Developing Effective Knowledge Management Systems

Knowledge is constantly generated through research and experience. With our total knowledge estimated to be doubling every 7 years, we question how effectively it is being managed to ensure that end-users are aware of, can rapidly access and are able to challenge and test this knowledge as it applies to their needs. How do users want and need knowledge – and are our current delivery mechanisms effectively meeting this need?

Use of Reclaimed Effluent Water in Australian Horticulture

Australia currently sends to ‘waste’ close to 86% of effluent water. In the past 4 years national re-use of effluent has doubled to 14% of all effluent produced, however this remains a small proportion of the amount of water still running to ‘waste’. The potential exists to use this water for horticultural production freeing up costly potable water. There are concerns about the use of recycled water from both a horticultural producer and consumer perspective. Participants (more)…

Views on Irrigation Policy Development - 2007 NPSI/IAL Travel Fellowship, Kimberley Graham

As water security threatens to be one of the greatest challenges facing mankind and as irrigation continues to use the largest share of water globally, attempting to devise solutions for this inherently complex issue drives my current honours research. My honours project focuses on understanding perceptions of proposed irrigation policy in Australia (of irrigation farmers, water distributors and government representatives) and the potential for perceptions to be incorporated into policy processes in (more)…

Water Smart Cotton and Grains in NSW

Irrigators want to improve WUE in terms of bales per ML or tonnes per ML, with the intention to maximise their profitability or $/ML. An important step to achieving this is through the adoption of irrigation management best practices. Consultants will be mentored to increase their knowledge, skills and confidence to deliver a range of irrigation services. Irrigation training, farm (more)…
