As urbanisation increases, how are engineers helping to ensure cities develop in a way that is sustainable, both for the communities that inhabit them and for the environment?
It is predicted that by 2030, more than 60 per cent of the world’s population will live in cities. This will grow to 70 per cent by 2050.
And, while cities occupy just three per cent of the Earth’s land, they account for 60 to 80 per cent of energy consumption, and 75 per cent of carbon emissions.
To mark World Engineering Day for Sustainable Development (4 March), we asked change-makers how engineering is shaping our lives.
With these figures in mind, experts are working to lessen the environmental impacts of our urban centres, including in the City of Adelaide.
Here are three ways city planners, engineers and others are attempting to make South Australia’s capital city more sustainable.
