Learn moreAbout Kalamunda's Climate Risk Profile
Kalamunda, located in the Darling Scarp, is vulnerable to several climate change impacts. The most significant risk is bushfire, given the surrounding forested areas and dry summer conditions. Rising temperatures and prolonged droughts are expected to exacerbate this risk, leading to more frequent and intense bushfire seasons.
Flooding is another concern, particularly during periods of heavy rainfall. Urban development and inadequate drainage infrastructure can contribute to localized flooding. Climate change projections indicate an increase in rainfall intensity, which could further elevate flood risk.
Heatwaves are also becoming more frequent and intense, posing a threat to vulnerable populations, such as the elderly and those with pre-existing health conditions. The urban heat island effect can amplify these impacts in built-up areas.
While Kalamunda is not directly exposed to coastal hazards, the broader region is experiencing sea-level rise and coastal erosion, which can indirectly affect the local economy and environment. Addressing these climate risks requires a combination of mitigation and adaptation strategies, including improved bushfire management, enhanced drainage infrastructure, and heatwave preparedness plans.
