Beach Road, Dulwich Hill: Planning urban infrastructure in an age of anthropogenic climate change
Australia is vulnerable to changing coastal conditions resulting from anthropogenic climate change. This vulnerability varies between cities and includes the risk of inundation of buildings and transport infrastructure from sea level rise, storm surge and major flooding events. The extent of impact is not fully known, nor is the timing of such impacts. There is a window of opportunity to adapt, but this involves hard decisions about relocating or protecting existing valuable infrastructure, siting new infrastructure in locations that in the short term may not appear optimal, and addressing the social justice implications of falling property values for low-lying, flood prone suburbs that are particularly vulnerable to a combination of sea-level rise and flooding from within the catchment. Planning urban infrastructure in an age of anthropogenic climate change requires dealing with uncertainty, complexity and accepting that while the costs of adaptation are high, the long-term costs of failure to adapt will be even higher.
