Dryland salinity, as an externality, has an impact on various public assets, including roads, biodiversity and public water supplies. This has been seen as an important justification for government to take action and internalise the pollution. Economic policy instruments have been identified as...

Sowing phases of French serradella ( Ornithopus sativus Brot.) pasture between extended cropping sequences in the Western Australian wheatbelt can sustain grain production through restoring soil fertility and reducing selective herbicide use. The objective of this article is to investigate the...

The inclusion of perennial pasture phases in cropping rotations has been widely promoted throughout Australia for reducing the incidence of dryland salinity. To a lesser extent, they have also been promoted to enhance the management of herbicideresistant weeds. No previous economic analysis of...

Abstract. This paper examines the optimal management of agricultural land through the use of non-crop inputs, such as fertiliser, and land uses that either degrade or restore productivity. We demonstrate the need to consider the relative total asset value of alternative crops over time. It is...

High nitrate concentrations have been reported within Canterbury aquifers due to agricultural intensification. Reducing nutrient loadings to groundwater by a reasonable degree is difficult for industry because of the anticipated cost of effective mitigation technologies. A novel alternative is...

A land retirement policy whereby land is taken out of agriculture and converted to natural vegetation or forestry has the potential to reduce environmental damage related to dryland salinity in Western Australia. This paper uses some recent results in the theory of directional distance functions...
