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...
