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...

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...

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...
