About Lorne's Climate Risk Profile

Lorne, a coastal town in Victoria, is increasingly vulnerable to the impacts of climate change. The primary risks include bushfires, flooding, heatwaves, and coastal erosion. The surrounding Otway Ranges contribute to the bushfire risk, while the coastal location makes it susceptible to sea level rise and storm surges.

Bushfire risk is a significant concern, with the potential for devastating fires during hot, dry summers. The increasing frequency and intensity of heatwaves further exacerbate this risk. Flooding is also a concern, particularly during periods of heavy rainfall, which can lead to flash flooding in low-lying areas.

Sea level rise poses a threat to beachfront properties and infrastructure, with potential for increased coastal erosion. The combined effects of these climate risks could have significant economic and social impacts on the community.

Adaptation measures are crucial to mitigate these risks, including improved bushfire management, flood mitigation strategies, and coastal protection measures. Community awareness and preparedness are also essential to ensure the safety and well-being of residents.
