Victoria's Infrastructure Faces Climate Change Threat
Victoria's public infrastructure is not prepared for the increasing frequency and intensity of extreme weather events caused by climate change. This could cost the state a staggering $1 trillion in disaster recovery by the end of the century, according to a report by Infrastructure Victoria (IV).
The report highlights the vulnerability of the state's roads, electricity networks, and buildings to more severe weather events like bushfires, floods, and storms. These events are expected to become more frequent and intense due to climate change.
The report emphasizes the need for proactive measures to protect Victoria's infrastructure. Currently, most infrastructure was not built to withstand the harsher conditions brought on by climate change. This means that the state faces significant costs for repairs and rebuilding after extreme weather events.
IV CEO Jonathan Spear emphasizes the importance of investing in more resilient infrastructure now. This will not only keep Victorians safer and businesses open but also reduce the long-term costs of disaster recovery.
The report proposes a shift from reactive to proactive infrastructure management. Traditionally, governments have waited until infrastructure fails before taking action. However, the report argues that investing in preventative measures will yield significant cost savings and reduce harm to communities.
flooding, bushfires, and extreme winds. The analysis shows that simple solutions can provide significant returns on investment.
For example, preventative maintenance on roads could save the government $5.10 for every dollar spent under current climate conditions. This figure increases to $8.29 under future conditions of increased extreme weather events.
Similarly, adapting the road network for bushfires and landslides could yield a return of $5.88 for every dollar spent under current conditions and $11.52 under future conditions.
The report also recommends replacing overhead electricity conductors with insulated cables to mitigate damage from extreme winds. This measure could provide a return of $1.16 for every dollar spent.
Dr Spear acknowledges that adapting infrastructure for more frequent weather events is not a simple task. There is no one-size-fits-all solution for the state. However, the report provides valuable insights for infrastructure managers to assess climate-related risks and develop effective adaptation strategies.
By investing in proactive measures and adapting infrastructure to the changing climate, Victoria can reduce the costs of disaster recovery, protect communities, and ensure the continued functioning of essential services.
