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 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...

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...

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...

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...

The Victorian Department of Sustainability and Environment (DSE) spent the latter decades of the 20th century fully integrating the surface and sub-surface drainage systems with the water distribution network in northern Victoria, thereby enabling complete recycling of outfalls, leaks and...

There is pressure in Australia for water management reform to ensure an efficient allocation of resources between productive uses and to provide adequate conservation of the environment. The establishment of water markets and trade has been seen as the primary mechanism for improving the...

Improving the conservation status of remnant native vegetation on private property (RNV) has a number of economic benefits. RNV can contribute to on-farm productivity through provision of unimproved grazing, timber products and stock shelter. It may contribute to enhancing the productivity of...

Sugar cane farms are the single biggest user of irrigation water in Queensland. Recent drought and unreliable rainfall patterns in areas traditionally reliant on rainfall for crop production has resulted in increasing interest in, and adoption of supplementary irrigation to help underpin...
