Blue-sky Thinking: Flood Risk Management and Blue-Green Infrastructure in Brisbane and Singapore

This research aims to explore the flood risk management strategies used after the 2011 Brisbane floods and to investigate the capacity for BGI in this management. A qualitative approach was used to investigate the primary case study of Brisbane in comparison to the secondary case study of Singapore, another high-density city that experiences flooding and incorporates BGI within its flood risk management at a national scale. As there are different mechanisms used to mitigate flood risks, it is important to identify how BGI can be implemented to effectively support existing infrastructure. Research methods included a literature review around flood risk management, BGI and the contexts of Brisbane and Singapore; a detailed analysis of planning and policy documents; and semi-structured interviews with academics, consultants and Brisbane City Council (BCC) staff.
