The issue of insecticide resistance to Helicoverpa insects is of increasing concern to the Australian cotton industry. In this paper we begin to consider this issue using bioeconomic modelling and analysis. We develop management strategies at the farm level within an integrated resistance...

To measure the value of the South Australian agrifood industry over time, food industry output, in terms of revenue along the value chain from production to consumption, is monitored. The agrifood industry is examined at the following levels: the farm gate, processor turnover, export and import...

Rainfall during the germination, growing and flowering periods is a major determinant of wheat yield. The degree of uncertainty attached to a wheat-yield prediction depends on whether the prediction is made before or after the rainfall in each period has been realised. Bayesian predictive...

Native vegetation management has become an issue of increasing community concern. Various initiatives have been established to address regional and state wide land degradation issues thus placing increasing pressure on land managers to develop sustainable native vegetation management solutions....

Wetland protection in the Upper South East (USE) of South Australia yields a range of private and social benefits. The profit motivation for private wetland owners to supply private benefits is clear whilst the provision of purely social benefits by private suppliers has no similar incentive....

This paper proposes modifications to the existing EU set-aside policy which are designed to alleviate the problem of output slippage associated with heterogeneous land quality by using "incentive-compatible" mechanisms drawn from principal-agent theory. Specifically, it is suggested that there...
