- Description
- Australia is a continent subject to climatic extremes, and losses from tropical cyclones and thunderstorms are significantly higher than other natural hazards. The intensity of tropical cyclones and severe storms are likely to increase due to climate change. Brisbane and the northeast coast of Queensland as regions where design wind specifications may be inadequate under either current or likely future climate conditions are particularly vulnerable. An appropriate adaptation strategy may be one that increase wind classifications for new houses leading to reduced vulnerability of new construction. The present paper will assess the damage risks, adaptation costs and cost-effectiveness of this adaptation measures for residential construction in the Queensland cities of Cairns, Townsville, Rockhampton and Brisbane assuming time-dependent changes in frequency and intensity of cyclonic and non-cyclonic winds to 2100. It was found that increasing design wind loads for new houses in Brisbane will lead to a net benefit of up to $8.3 billion by 2100 assuming a discount rate of 4%. The sensitivity of results to discount rate, including intergenerational effects, was studied.
