The extended dry conditions in the Murray Darling Basin have resulted in unprecedented levels of reduced water availability for both irrigators and the environment. Concerns over environmental degradation and the health of the river Murray have prompted the Federal and State Governments to...

The economic impacts of altering quarantine policies are divided into two main areas: trade evaluations, utilising a partial equilibrium approach to determine the benefits of market liberalisation; or pest management economics, used to determine the on-ground impacts of introduced species. This...

Questions relating to the allocation and management of risk have played a central role in the development of the National Water Initiative, particularly as it has applied to the Murray- Darling Basin. The central issues of efficiency and equity in allocations are best understood by considering...

The Murray-Darling Basin comprises over 1 million km2; it lies within four states and one territory; and over 12, 800 GL of irrigation water is used to produce over 40% of the nation's gross value of agricultural production. This production is used by a diverse collection of some-times mutually...

The supply of water for irrigation is subject to climatic and policy uncertainty. The object of the present paper is to show how the linear and non-linear programming models commonly used in modelling problems such as those arising in the Murray–Darling Basin may be adapted to incorporate a...

Human activity has modified the environment at all scales from the smallest ecosystems to the global climate systems. In the analysis of the Murray-Darling Basin, it is necessary to take account of effects of human activity ranging from local changes in water tables and soil structure through...

The worldwide scare over the 'Y2K bug result in the expenditure of hundreds of billions of dollars on Y2K compliance and conversion policies. Most of this can be seen, in retrospect, to have been unproductive or, at least, misdirected. In this paper, the technological and institutional factors...
