In face of climate change and other environmental challenges, inclusion of perennial forage shrubs in Australian agricultural systems has the potential to deliver multiple benefits: increased whole-farm profitability and improved natural resource management. The profitability of shrubs was...

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...

Dryland salinity is one of the most pressing land management problems in Western Australia. A number of projects are in progress to provide a more comprehensive picture of the location and extent of potentially saline areas in the landscape. Associated with some of these projects, a large number...

Hydrologists predict that salinity in the agricultural region of Western Australia will eventually affect an average of 30 percent of the landscape if nothing is done to reduce current levels of recharge. The scale of tree planting and other works thought to be required for controlling salinity...

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...

The spatial pattern of landscape reconstruction makes a substantial difference to environmental outcomes. We develop a spatially explicit bio-economic model that optimises the reconstruction of a heavily cleared landscape through revegetation. The model determines the spatial priorities for...

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...

Lifestyle landowners value land for its amenities and ecological characteristics and could play an important role in managing and conserving native vegetation in multifunctional rural landscapes. We quantify values of ecosystem services captured by owners of rural lifestyle properties in...

Groundwater extraction can have varied and diffuse effects. Negative external effects may include costs imposed on other groundwater users and on surrounding ecosystems. Environmental damages are commonly not reflected in market transactions. Groundwater transfers have the potential to cause...
