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 effects of global climate change on agriculture will be diverse and complex. Some important qualitative conclusions emerge from the literature. First, it is important to focus on the rate at which climate changes and the capacity of farmers to adjust, rather than on absolute changes in...

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...

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...

The paper consists of a summary of the main sources of uncertainty about climate change, and a discussion of the major implications for economic analysis and the formulation of climate policy. Uncertainty typically implies that the optimal policy is more risk-averse than otherwise, and therefore...

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 demonstration that, in the presence of overlapping generations and under standard conditions for a social welfare ordering (Pareto optimality, transitivity, independence), the only ordering consistent with utilitarianism for all people currently alive at any given point in time is...

The terms ‘grandfather clause’ and ‘grandfathering’ describe elements of a policy program in which existing participants in an activity are protected from the impact of regulations, restrictions or charges applied to new entrants. In this paper, the role of grandfathering in the design...
