| A range of biophysical and financial factors, including the crop response to available water and the cost of irrigation, significantly impact on the economic benefits from using irrigation. Research tools have been developed in a multi-disciplinary environment to allow for the assessment of the economic benefits associated with using irrigation. This paper adopts the 1996-1997 season in Bundaberg as a case study and develops arguments for best use of limited water based on current economic and biophysical modelling capability. A selection of irrigation ‘options’ were chosen for investigation based on combinations of soil type, allocation, critical fraction of available soil water (FASW) to irrigate, irrigation amount, and age of crop for irrigation... |

| Sugarcane farmers in many districts are considering on-farm water storages (OFWS’s) as a means of countering ongoing water shortages. OFWS’s are attractive because they can be used to capture runoff and tailwater, and for the temporary storage of surplus water from other irrigation sources (eg allocation, out of allocation, water harvesting etc), thereby providing increased flexibility in managing limited water supplies. The decision to invest in such storages is, however, complex and multi-facetted, requiring assessment of a range of biophysical, economic, legislative and social factors. Computer-based simulation models can potentially capture many of these factors and their interactions, and hence, can play a useful decision support role. In this paper,... |
