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...

In the past year, climate change has moved from political controversy to political consensus; at least, in relation for price-based policies the need to limit emissions. Uncertainties remain but with both major parties proposing to develop an emissions trading regime, it is timely to highlight...

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...

This review will focus on the question of discounting. The paper begins with an outline of the expected utility model used in the Stern Review. Next, the question of ‘inherent discounting’, that is, the idea that future outcomes should be discounted simply because they are in the future, is...

It is now virtually certain that Australia and the world will experience significant climate change over the next century, as a result of human-caused emissions of carbon dioxide (CO2) and other greenhouse gases. This note is a brief discussion of the projected effects of climate change on...

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...

This article briefly outlines the cause of global warming, its trends and consequences as indicated by the International Panel on Climate Change. Sea-level rise is one consequence of particular concern to Pacific island states. It also reviews the views of economists about connections between...

The problem of climate change has been described as ‘a unique challenge for economics: it is the greatest and. widest-ranging market failure ever seen’ (Stern 2007, p. i). Among the factors that make climate change a difficult, the most important, arguably, is uncertainty about the future...

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 precautionary principle has been proposed as a basis making decisions about environmental health under conditions of uncertainty, but remains controversial. This paper shows how the precautionary principle may be interpreted as a guide to decision making in complex systems characterised by...
