The economic potential of carbon is the focus of a new fire project on the Tiwi Islands, 80 kilometres north of Darwin in the Northern Territory and home to 2,000 Aboriginal Australians. Nearly half of the Tiwi Islands are burnt every year, resulting in significant greenhouse gas emissions. Reducing the extent of fire may provide substantial financial benefits under the emerging carbon economy.

Invasive ants are among the greatest environmental, social and economic threats to Australia, potentially costing the nation more than $1 billion annually. However, knowledge of the basic biology of these pest species remains rudimentary, and many management operations have been unsuccessful.

Why do some plant and animal species thrive in the city while others disappear?

Most ecological studies are done in natural environments not in towns and cities so we lack information on urban ecology.

A team from Melbourne’s Royal Botanic Gardens is changing that.

LED lighting is sweeping the world. It’s energy efficient, long lasting, and could save users billions of dollars worldwide and dramatically reduce carbon emissions. But it’s still a young technology. Much more efficient lights are on the way.

Building water sensitive cities

water4a_300x180Staff in a Monash University-led project, called Water Sensitive Cities, believe the time is right for a bold idea that could produce 20 to 30 per cent of Melbourne’s future water needs.

Annually, almost as much stormwater falls on Melbourne as its citizens use, but only a fraction is captured and reused. Billions of litres of stormwater literally go down the drain and into Port Phillip Bay, degrading the ecological health of Melbourne streams and the bay.
