About Geeveston's Climate Risk Profile

Geeveston, nestled in the Huon Valley, is increasingly vulnerable to the impacts of climate change. The primary concerns are related to flooding from the Huon River and the increasing risk of bushfires due to hotter, drier conditions.

The town's proximity to the river makes it susceptible to flooding, especially during periods of heavy rainfall. Climate change projections indicate an increase in rainfall intensity, which could lead to more frequent and severe flood events. This poses a threat to residential and commercial properties located near the river.

Bushfire risk is also a significant concern. The surrounding bushland creates a potential fire hazard, and hotter, drier summers are expected to increase the likelihood of bushfires. This could have devastating consequences for the town and its residents.

While Geeveston is not directly exposed to coastal hazards, changes in sea level can influence riverine flooding. It is crucial for the town to implement adaptation measures to mitigate these risks and protect its community.

Overall, Geeveston needs to focus on improving its flood defenses, managing bushfire risks, and preparing for more frequent and intense heatwaves. By taking proactive steps, the town can enhance its resilience to the impacts of climate change.
