Risk communication and risk perception: lessons from the 2011 floods in Brisbane, Australia.

Risk communication and risk perception are critical factors in disaster management. Governments at all levels play a part in communicating risk, whereas the perception of risk entails active roles by community participants, including potential and actual victims of disasters. This paper discusses these matters in relation to the floods in Brisbane, Australia, in 2011. The findings are based on interviews with representatives of households whose dwellings or business premises were fully or partially inundated by the waters. The research shows how important it is to recognise the problems of institutional fragmentation in terms of communication and the active engagement of recipients in understanding and interpreting flood risk information (especially for slow-onset riverine flooding, such as that suffered by Brisbane). Locally targeted information on risk is of vital importance in avoiding the misinterpretation of warning information in relation to environmental cues and in promoting adequate responses. The paper concludes with some recommendations.
