This paper explores some of the important issues that influence the magnitude of receival site grain catchments in Australia. Changes in grain harvests, transport and grain handling technologies and costs; changes in farming systems, crop yields and harvesting capacity; investments in roads and...

Environmental policy evaluation is characterised by a paucity of information. The novel technique of robust mathematical programming is introduced as a means to proactively account for this uncertainty in policy analysis. The procedure allows identification of expected bounds on the range of...

Regional councils throughout New Zealand are in the process of drawing up plans to enable them to meet the requirements of the Resource Management Act and the National Policy Statement on freshwater. Some councils are working on targets for nutrient leaching at the catchment level and are...

Models used for policy evaluation rarely consider firm heterogeneity, despite its importance for instrument design. This study considers agent heterogeneity explicitly in the evaluation of policies for nonpoint pollution control through the integration of decomposition and calibration procedures...

This paper uses variance decomposition modelling to explore how wheat revenuevolatility in Australia has changed spatially and temporally. The components ofrevenue variance are the variances and covariances of wheat prices, the area of wheatharvested and the yield of wheat. The key finding is...

Australian crop and livestock farmers face uncertain climate change and variability and a challenge for adaptation decisions. These decisions can be (1) adjustments to practices and technologies, (2) changes to production systems, or (3) transformation of industries, for example, by relocation...

The wine industry in Western Australia, like its counterparts in some other wine-making regions across the globe, faces some interesting investment choices regarding the relative merits of expenditure on promotion or production and whether export or domestic markets should be the focus for sales...
