Potential for change in the mix of irrigated enterprises was estimated for a catchment in the Shepparton irrigation region using linear programming. The model allocated resources to maximise net income in each of the next five decades as if the catchment were one farm. Change was driven by price...

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...

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...

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...

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...

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...

Net annual costs for disposal by pumping to the Murray River, an on-farm evaporation basin, conjunctive use with surface water to irrigate dairy pasture, and undiluted irrigation of a salt tolerant grass were estimated and compared. Total conjunctive use (TCU) is the cheapest option below 10dS/m...
