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...

This study investigates the role that certified-organic farming systems play in irrigation water-use in the Murray–Darling Basin, where large-scale government policy has focussed on returning water from irrigation to key ecological sites. Information from Australia's agricultural census in...

Governments in Australia are purchasing water entitlements to secure water for environmental benefit, but entitlements generate an allocation profile that does not correspond fully to environmental flow requirements. Therefore, how environmental managers will operate to deliver small and...

Large scale forest plantations in the Murray–Darling Basin are a possible carbon sequestration mechanism which may be adopted in response to the introduction of a carbon price. However, increased tree plantation will be associated with reduced inflows to river systems because of increased...

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...
