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...

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...

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...

The development of a market in groundwater usage rights can be inhibited by constraints arising from the institutional context. Such impediments may reduce the potential gains from trade and may generate high transaction costs for prospective traders. We analyse the regulations and policies...

Invasive species are significant threats to biodiversity, natural ecosystems and agriculture leading to large worldwide economic and environmental damage. Spread and control of invasive species are stochastic processes with important spatial dimensions. Most economic studies of invasive species...

Opportunity cost constitutes a substantial component of the costs of ecological restoration projects undertaken in agricultural landscapes. Private benefits generated by restored environmental assets are also important in determining the success of restoration projects. In this study, we compare...

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...

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...

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...
