About Girvan's Climate Risk Profile

Girvan, located in New South Wales, is susceptible to a range of climate-related risks. The primary concerns include increased flooding due to more intense rainfall and rising sea levels, as well as more frequent and severe heatwaves.

The area's proximity to waterways makes it vulnerable to both riverine and flash flooding. Climate change models predict an increase in extreme rainfall events, which could overwhelm existing drainage infrastructure and lead to property damage.

Rising temperatures pose a significant threat to public health, especially for elderly and vulnerable populations. More frequent and prolonged heatwaves can lead to heatstroke and other heat-related illnesses. Coastal erosion and inundation due to sea level rise also present a long-term challenge for the community.

Addressing these risks requires a combination of mitigation and adaptation strategies. This includes investing in improved drainage infrastructure, implementing heatwave early warning systems, and developing coastal management plans to protect vulnerable areas.
