To understand the importance of risk in farmers' decisions on whether or not to adopt new grain legumes.
1. Use surveys of farmers to understand and measure farmers' perceptions of riskiness of grain legumes;
2. Use economic models and models of farmer decision-making to understand how risk affects farmers' decisions to adopt grain legumes;
3. Use this information (in conjunction with other economic analyses) to assess grain legume species and varieties for release.
Progress: Final report presented (UWA-261). This study investigated the impact of price and yield uncertainty on the value of new legumes and their place in a Mediterranean region of Western Australia. It used the stochastic bioeconomic farming system model MUDAS (Model of an Uncertain Dryland Agricultural System) to integrate climatic, agronomic and economic information. A robust finding is that chick peas in rotation with wheat on some clayey-loam soil classes are a profitable addition to optimal farm plans, increasing the certainty equivalence of profit on a typical farm by 7 per cent. By contrast, modelling results for field peas and faba beans suggest they are likely to form a minor role in the farming system, being occasionally selected under certain price and weather-year conditions. Modelling results highlight a farmer’s attitude to risk and the proportion of the farm area with suitable soils as important determinants of the role and value of the new legumes in the farming system. These findings, if supported by further investigations, have important implications for breeding and agronomic research.
