About Cardigan's Climate Risk Profile

Cardigan, located near Ballarat, Victoria, is increasingly vulnerable to the impacts of climate change. The primary concerns for this suburb are flooding and heatwaves, with bushfire risk also present.

Flooding is a significant concern due to the suburb's proximity to waterways and low-lying areas. Increased rainfall intensity, driven by climate change, is expected to worsen flood events. Inadequate drainage infrastructure and ongoing urban development further exacerbate this risk.

Heatwaves are also a growing threat, with rising global temperatures leading to more frequent and intense heat events. This poses a particular risk to vulnerable populations, such as the elderly and those with chronic health conditions. The urban heat island effect can further amplify these impacts.

While bushfire risk is moderate, the surrounding grasslands and bushland create a potential hazard. Hot, dry conditions and strong winds can increase the likelihood of bushfires, posing a threat to properties and lives. Residents should maintain awareness and preparedness during the bushfire season.

Addressing these climate risks requires a multi-faceted approach, including improved drainage infrastructure, heatwave preparedness plans, and bushfire mitigation strategies. Community engagement and education are also crucial to building resilience and ensuring the safety of residents.
