A range of biophysical and financial factors, including the crop response to availablewater and the cost of irrigation, significantly impact on the economic benefits from usingirrigation. Research tools have been developed in a multi-disciplinary environment toallow for the assessment of the economic benefits associated with using irrigation. Thispaper adopts the 1996-1997 season in Bundaberg as a case study and develops argumentsfor best use of limited water based on current economic and biophysical modellingcapability. A selection of irrigation ‘options’ were chosen for investigation based oncombinations of soil type, allocation, critical fraction of available soil water (FASW) toirrigate, irrigation amount, and age of crop for irrigation commencement. The influenceof these options on cane production is explored in a farm-level linear programmingmodel. There appears to be a sound economic argument for further biophysical researchinto the crop response to irrigation, based on the sensitivity of farm incomes to choice ofirrigation strategy.
