About Narwee's Climate Risk Profile

Narwee, a suburb in New South Wales, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding due to increased rainfall intensity and heatwaves exacerbated by the urban heat island effect.

The risk of flooding is driven by the suburb's proximity to local waterways and relatively flat terrain. Climate change projections indicate an increase in extreme rainfall events, which could overwhelm existing drainage infrastructure and lead to more frequent and severe flooding.

Heatwaves pose a significant threat to the health and well-being of Narwee residents, particularly the elderly and those with pre-existing health conditions. The urban heat island effect, caused by the concentration of buildings and paved surfaces, traps heat and raises temperatures even further.

While the risk of bushfires is relatively low, surrounding bushland areas could pose a threat during periods of extreme heat and dryness. It is important for residents to maintain their properties and be aware of bushfire safety guidelines.

Addressing these climate risks requires a multi-faceted approach, including investments in improved drainage infrastructure, urban greening initiatives to reduce the urban heat island effect, and community education programs to raise awareness of climate risks and promote preparedness.
