The Murray-Darling Basin faces increasing pressure on water quantity and quality. In 2006-07, salt interception schemes implemented as part of the Murray-Darling Basin Salinity Management strategy removed over 470,000 tonnes of salt from the water supply, reducing the salinity of water flowing...

Climate change is likely to have substantial effects on irrigated agriculture. It is anticipated that many areas that are already dry will become drier, while areas that already receive high rainfall may experience further increases. Extreme climate events such as droughts are likely to become...

To mitigate environmental damage from the over allocation of water property rights to irrigation in Australia’s Murray-Darling Basin, the Federal Government has introduced a Buy-Back policy. However, the conjunctive nature of water resources in the Murray- Darling Basin is highly variable....

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...

For an irrigator, investments in on-farm water infrastructure that increase the marginal productivity of water may improve use efficiency. However, increasing on-farm water use efficiency invariably diminishes return flows, compromising the ability to maintain sufficient water flows in streams...

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...

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...

It is likely that climate change will be associated with reductions in inflows of water to the Murray-Darling Basin. In this study, we analyse the effects of climate change in the Murray-Darling Basin using a simulation model that incorporates a state-contingent representation of uncertainty....

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...
