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...

This paper will briefly describe the history and intent of the NTA 1993; survey outcomes flowing from its implementation, especially in reference to economic implications of agreements between parties; and consider future prospects, particularly by reference to the amended legislation which came...

Much of Australia’s native vegetation has been cleared or altered as a result of agricultural development. The native vegetation that remains on private land is highly fragmented and continues to be degraded and modified due to various land use and environmental pressures. One of the major...

Potential for change in the mix of irrigated enterprises was estimated for a catchment in the Shepparton irrigation region using linear programming. The model allocated resources to maximise net income in each of the next five decades as if the catchment were one farm. Change was driven by price...

The Land and Water Management Plans (LWMPs) developed for the irrigation districts in the Murray region of NSW are said to be at the forefront of institutional innovation for integrated resource management. Farmers have been strongly involved both in the development of the Plans (for which...

Evaluating land use change in economic frameworks often requires non-market values to be assessed. However non-market valuation experiments can be sensitive to the way the trade offs are framed. The aim of the research reported in this paper was to examine the influence of varying the valuation...
