About Maroona's Climate Risk Profile

Maroona, Victoria, is increasingly vulnerable to the impacts of climate change. The primary risks include bushfires, flooding, and heatwaves. Changes in rainfall patterns and rising temperatures are expected to exacerbate these hazards in the coming decades.

The risk of bushfires is significant due to the surrounding grasslands and bushland. Drier conditions and more frequent heatwaves increase the likelihood of fire ignition and spread. Residents should maintain their properties and be prepared to evacuate if necessary.

Flooding is another concern, particularly during periods of heavy rainfall. Local waterways can overflow, inundating low-lying areas. Improved drainage infrastructure and flood management strategies are needed to mitigate this risk.

Heatwaves are becoming more frequent and intense, posing a threat to vulnerable populations, such as the elderly and those with chronic health conditions. Ensuring access to cooling centers and providing heat safety information are important adaptation measures.

While coastal risks are minimal due to Maroona's inland location, the community should still be aware of the broader impacts of climate change and support efforts to reduce greenhouse gas emissions. Adaptation measures focused on bushfire and flood preparedness, as well as heatwave response, are crucial for building resilience in Maroona.
