An early-mid project evaluation of the benefits and costs of the Tragowel Plains Salinity Management Plan estimated the net cost after six years at A$ 5.5 million. The cumulative cash flows for the water transfer, drainage and halophyte programs were all positive with benefit to cost ratios...

An allowance for water use is part of the agronomic analysis implicit in the foundation of any sensible economic evaluation of crop response or change of farming system. Diminishing returns to investment in water use efficiency imply that the optimum level of investment is determined by the...

A false expectation based on the notion that it is easy to raise water use efficiency, and that all increases in water use efficiency will also increase net social welfare, will lead to gross underestimation of the economic impact of reduced irrigation allocations in the Murray-Darling Basin. A...

Water use efficiency data was used to estimate the impact of reducing sales water allocations on a range of irrigated dairy farms categorised according to intensity of water right. The expected deficiency in available water was estimated for each farm category on the basis of historical demand...

Approaches to valuing regional responses in plant productivity from investment in natural resource management are reviewed. The usefulness of data from surveys for estimating marginal physical product is discussed. Since investment reduces declining trends in productivity, an estimate of value...

Consultation with industry identified a range of knowledge and information management tools required for building decision support systems (DSSs) that can help guide sustainable development of irrigated dairy production in the Murray Region. Individual production systems vary in complexity and...
