Botany Bay and Rockdale have been identified as areas considered most vulnerable to climate change in the Sydney region.
A new study by the CSIRO, the University of the Sunshine Coast, and WWF Australia, looked at the effect of rising sea levels, extreme rainfall, and storm surges across 15 areas either on the ocean front or on major estuaries
The Sydney Coastal Councils Group will use the information to improve their planning and development on low-lying level areas and adapt to a changing landscape.
They hope to try and set up better management practices to avoid the risk of long-term damage.
CSIRO scientist Dr Ben Preston says Sydney’s low lying areas will have an increased risk of inundation and erosion.
“Those areas along the Tasman Sea are some of the hotspots, such as Narrabeen Beach for example, are certainly at risk,” he said.
“That’s not particularly a surprise. What we also noticed was the north end of Botany Bay tends to be a flat, low-lying area which might also have to face additional problems from things like sea level rise or extreme rainfall or urban flooding.”
Dr Preston says the sea level rise will change the coastline.
“Looking at a place like Sydney, you are going to see a lot of variability even in a smaller geographic area depending on the type of impact,” he said.
“It could vary from one property to another.”
The study identified problem areas based on how much the area would be impacted by bushfire, heat-related health effects, sea level rises and the vulnerability of its natural ecosystems. ABC
