Ano: 2006 URL: http://purl.umn.edu/116970 Climate change and climate uncertainty in the Murray-Darling Basin AgEcon Adamson, David; Mallawaarachchi, Thilak; Quiggin, John C.. Human activity has modified the environment at all scales from the smallest ecosystems to the global climate systems. In the analysis of the Murray-Darling Basin, it is necessary to take account of effects of human activity ranging from local changes in water tables and soil structure through basin-level effects of the expansion of irrigation to changes in precipitation pattern arising from the accumulation of greenhouse gases in the atmosphere. In this paper, we analyse the impact of, and adjustments to, climate change in the Murray-Darling Basin, using a simulation model that incorporates a state-contingent representation of uncertainty.

Ano: 2007 URL: http://purl.umn.edu/10361 Re-examining the economic options for import risk assessments AgEcon Adamson, David; Cook, David C.. 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 paper rationalises why these approaches need to be brought together within the policy framework of import risk assessments to provide a greater understanding of the benefits and risks from market liberalisation.

Ano: 2007 URL: http://purl.umn.edu/10365 Turning Water into Carbon: Carbon sequestration vs. water flow in the Murray-Darling Basin AgEcon Schrobback, Peggy; Adamson, David; Quiggin, John C.. 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 and evaporation. Therefore, an unregulated change in land management is most likely to have a dramatic impact on the water availability. This will exacerbate the impacts of climate change projected in the Garnaut Review. This paper examines the implications of unrestricted changes in land use. These results should suggest the true costs to society from carbon sequestration by determining the tradeoffs between timber production and agricultural products.

Ano: 2009 URL: http://purl.umn.edu/47616 Water use and salinity in the Murray–Darling Basin: A state-contingent model AgEcon Adamson, David; Mallawaarachchi, Thilak; Quiggin, John C.. 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 state-contingent representation of uncertainty. Estimates showing the potential value of improved water use are also derived. Tipo: Journal Article Palavras-chave: Irrigation; Salinity; Uncertainty; Resource /Energy Economics and Policy.
