Helicoverpa spp. (heliothis) are a major insect pest of cotton, grains and horticulture in the Murray‐ Darling Basin. Climate change is likely to make conditions more favourable for heliothis. This could cause regional comparative advantages in irrigation systems to change as management costs...

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 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...

The long-term success of the Basin Plan and the Buy-Back will be judged by the capacity of the allocated public funding to deliver water to the environment, potable water supplies for the community and water for irrigation. Water property rights in the Murray-Darling Basin can be divided into...

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

Climate change is likely to have substantial effects on irrigated agriculture. Extreme climate events such as droughts are likely to become more common. These patterns are evident in median projections of climate change for the Murray–Darling Basin in Australia. Understanding climate change...

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 construction of the Snowy Mountains Hydro-electric Scheme in the 1960s resulted in the diversion of 99% of the Snowy River's natural flow into the Murray and Murrumbidgee river systems. In 2000, the NSW, Victorian and Commonwealth governments agreed to restore between 21 per cent and 28 per...

Large scale forest plantations in the Murray-Darling Basin may be embraced as a carbon sequestration mechanism under a Carbon Pollution Reduction Scheme. However, increased tree plantation will be associated with reduced inflows to river systems because of increased transpiration, interception...

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...
