| Subject matter research has made many contributions to small grain production in the Western Cape province of South Africa, but much of this focuses on single commodities and is undertaken within conventional disciplinary boundaries (e.g. soil science, genetics, economics). The result is that the solutions offered often have knock-on effects that are not properly accounted for by researchers. Expert group discussions, as a research method, are suitable, firstly, for gathering information in a meaningful manner and, secondly, to stimulate individual creativity by presenting alternative perspectives provided by various participating experts. In support of expert group discussions, multi-period wholefarm simulation models were developed. This type of... |

| The impact of two greenhouse gas abatement policies on two Mediterranean-type farming systems, grazing dominant and cropping dominant, is examined. The policies analysed are; an emissions taxation policy and an emissions restrictions policy. For both farming systems the restriction policy is found to be more effective and economically efficient than the carbon permit policy. Absolute cost of abatement is less for the livestock dominant system but relative cost is greater, because of lower total farm profits. The analysis found that at predicted emissions permit prices, trees, if credited as a carbon sink, would be adopted by both farming systems to offset farm greenhouse gas emissions. |

| Using an expected mean-variance model the changes in farm enterprise levels and indirect utility were examined under conditions of risk aversion, budget constraints and gross margin variance. An extension of the comparative statics of the expected mean-variance model was adopted by introducing a budget constraint into the constrained optimisation problem. A 10-year expected mean-variance whole-farm model was solved for a farm in the wheat-sheep zone of Australia to provide an empirical example. Results were obtained using no planning horizon (the static model) and then with a five-year rolling planning horizon (the dynamic model). In addition, enterprise levels were constrained to match levels observed on the farm so as to compare incomes between the... |
