The Central Highlands to the east of Melbourne are home to incredible stands of Mountain Ash (Eucalyptus regnans). They are valuable in their own right and also offer space, quiet, recreation, and are a home to a wealth of animal species. The catchments of the Central Highlands also provide much of Melbourne’s drinking water.
According to new research, Melbourne faces a rising threat to it’s water supplies from climate change as higher temperatures diminish inflows while pushing up demand.
A paper published by Environment Research Letters shows a “substantially” amplified risk for Melbourne’s water availability if global temperatures rise 2 degrees above pre-industrial levels rather than the 1.5-degree target set by the Paris climate agreement.
