An environmental engineering expert at The University of Western Australia said ‘greening’ the suburbs of Perth will help reduce the emerging urban health crisis of heatwaves.
UWA’s Professor of Environmental Engineering Anas Ghadouani is Executive Director of the $120 million Cooperative Research Centre for Water Sensitive Cities (CRCWSC), a national research centre funded by the Australian Government and industry to help transform water management across Australia.
He said water plays a key role in making cities and towns more liveable, particularly during times of soaring temperatures.
“There is strong evidence that a green, leafy park, tree-lined street or urban waterway could drop the local temperatures by several degrees,” Professor Ghadouani said.
“This cooling is extremely important for reducing heat-related deaths, particularly during the very hot days of the year, which we’re seeing more often and for longer periods nowadays.
“Water is crucially important in this because just as households and industries depend on it, so does the vegetation in our cities.”
Professor Ghadouani says that while the Bureau of Meteorology may show a reading of 40C in some locations, people could feel temperatures of up to 50C, particularly if there is no green infrastructure in that suburb.
He said research showed that Perth’s most vulnerable ‘hotspots’ include the suburbs of Bentley, City of Canning, Woodvale, Kingsley, Booragoon, Como, Hamilton Hill, Coolbellup, and Stirling. More detailed information about your suburb’s heat vulnerability can be found here.
Professor Ghadouani said the CRCWSC is identifying novel solutions to keep our cities green using new water sources and efficient water usage.
