About Mount Barker's Climate Risk Profile

Mount Barker, located in the Adelaide Hills, is exposed to a range of climate-related risks. Flooding is a concern due to heavy rainfall events and the presence of local creeks. Bushfire risk is elevated due to the surrounding bushland, particularly during hot and dry summers.

Heatwaves pose a significant threat, especially to vulnerable populations, with increasing temperatures expected due to climate change. While Mount Barker is not directly exposed to coastal hazards, the broader region may experience indirect impacts.

Climate change projections indicate an increase in the frequency and intensity of extreme weather events, including floods, bushfires, and heatwaves. This necessitates proactive adaptation measures to protect residents and infrastructure.

Local authorities are working to address these risks through various strategies, including improved flood management, bushfire prevention, and heatwave preparedness. Residents can also take individual actions to reduce their vulnerability to climate change impacts.
