Learn moreAbout Tawonga South's Climate Risk Profile
Tawonga South, nestled in the Alpine region of Victoria, is increasingly vulnerable to the impacts of climate change. The primary concerns are rising flood risk due to more intense rainfall events, heightened bushfire danger during prolonged dry periods, and increasing heatwave frequency and intensity.
The Kiewa River poses a significant flood threat to properties in low-lying areas. Climate projections indicate that rainfall intensity will increase, leading to more frequent and severe flooding events. This could damage homes, businesses, and infrastructure, disrupting daily life and causing economic losses.
The surrounding bushland presents a substantial bushfire risk, especially during the summer months. Higher temperatures and drier conditions are expected to exacerbate this risk, increasing the likelihood of fire ignition and spread. Residents need to be vigilant and prepared to evacuate if necessary.
Heatwaves are also becoming more common and intense, posing a health risk to vulnerable populations, such as the elderly and those with chronic illnesses. It is crucial to take precautions during heatwaves, such as staying hydrated, seeking air-conditioned environments, and checking on neighbors.
Addressing these climate risks requires a multi-faceted approach, including investing in flood mitigation infrastructure, implementing bushfire prevention measures, and promoting heatwave preparedness. Community engagement and education are also essential to ensure that residents are aware of the risks and know how to protect themselves.
