Water Law and Planning Frameworks under Climate Change Variability: Systemic and Adaptive Management of Flood Risk

Abstract

Climate change is predicted to bring more extreme climatic variability to Australia. Yet recent reforms to Australian water law and governance have typically focused on water scarcity, not floods. In the summer of 2010/2011, devastating floods in a major urban centre and in regional areas were powerful reminders of the need for more systemic and adaptive responses for water resources management. Using Queensland and Victoria as case studies, the article demonstrates how the water law frameworks in both states assume 'stationarity' through the adoption of standards such as the 1:100 year flood event probability-an assumption that climate change has rendered unreliable. The article then examin..
