| A Dynamic programming Model is used to select the most profitable crop rotation from seven crop alternatives including pasture. Crop yields within a rotation are estimated by specifying growing season rainfall, water use efficiency and weed and disease penalties caused by the three previous years crop history. A provision exists to include the effect on yield of other natural resource limitations. Regional variations can be accounted for by varying rainfall, management practices, yield penalties and input costs. A nitrogen-phosphorous calculator ensures sufficient fertiliser is applied for the crop to achieve its expected yield. This approach can be used to measure the productivity implications of advances in technology as well as the impact of rainfall,... |

| On 29th April 2008, Senator Penny Wong outlined details of Water for the Future; the Rudd Government’s $12.9 billion plan to secure the long term water supply of all Australians. Funding under Water for the Future will be used to support significant water reform across the country. In order to formulate strategies to achieve the objectives of the Plan, decision makers will require information related to the relative profitability of different irrigation activities, such as production costs and returns, as well as the potential irrigator response to and impacts of reductions in water availability or changes to water policy more generally. The aim of this paper is to highlight the potential for unexpected outcomes to arise from policies which are formulated... |
