Turn Down the Heat

 

Western Sydney is hot and is set to get hotter due to a combination of climate change, local geography, and rapid urbanisation – where green fields make way for new housing developments.

 

Urban development in particular, is creating significant local heating whereby hard, man-made surfaces absorb and hold on to heat, raising the temperature in our suburbs.

 

Heat causes major liveability and resilience problems with critical impacts for human health, infrastructure, emergency services and the natural environment.

 

Urban Heat Impacts diagram - Urban heat has an impact on people, infrastructure the economy and environment. Heatwaves have killed more Australian than any other natural disaster. 13% increase in mortality has been seen during past heatwaves. Of all the extreme weather events, heatwaves place the greatest pressure on our city's infrastructure assets. Extreme heat causes dramatic reduction in the amenity of an environment from teh neighbourhood to the city level. Public spaces and other facilities can become unusable. Economic impacts of heat are also significant. Western Sydney households use 100% more energy for cooling than eastern Sydney households. The broader economic burden of heatwaves in Western Sydney is thought to be significant, however the exact cost remains unknown and challenging to quantify. It is estimated that an annual productivity loss of $6.9 billion can be attributed to heatwaves across Australia.

The impacts of heat are already being felt across Western Sydney. We urgently need to respond with strategies that minimise the impacts of intense shocks such as heatwaves and the ongoing stress of frequent hot and very hot weather.

 

It is critical that we improve our region’s resilience to urban heat. A resilience approach involves not only reducing urban heat, but also helping people adapt, and being prepared to respond in extreme events.

 

 

Turn Down the Heat Strategy cover

Turn Down the Heat Strategy and Action Plan (2018)

Turn Down the Heat is a WSROC-led initiative that takes a collaborative, multi-sector approach to building a cooler, more resilient future for Western Sydney.

 

The initiative is guided by the Turn Down the Heat Strategy and Action Plan (2018) which was co-designed by over 55 stakeholders who recognise that the response to extreme heat and heatwaves is a shared responsibility.

 

The strategy outlines five key areas for action:

 

    • Take action together
    • Design and plan to cool the built environment
    • Cool with green space and water
    • Build a community that is healhty and prepared
    • Innovative and responsive infrastructure

 

Current initiatives:

WSROC is currently delivering four grant-funded projects under the Turn Down the Heat Strategy:

 

 

In addition, a range of other initiatives from our partner organisations can be found on our Turn Down the Heat resources page.

 

 

How can you become involved?

We hope you see a role for yourself and your organisation in the ongoing work to reduce the impacts of urban heat in Western Sydney.

 

SUPPORT THE STRATEGY 

Advocate to make urban heat a priority issue and endorse this Turn Down the Heat Strategy by using it as a framework to guide and promote actions within your organisation.

 

INITIATIVES WITHIN YOUR ORGANISTION 

Identify what your organisation is already doing. Is urban heat reflected in your policy or guidelines for:
o Planning and development?
o Green space management?
o Community education?
o Emergency response planning?
o Infrastructure and asset resilience?
