Australia wastes 7.3 million tonnes of food a year, with Australian households responsible for dumping more than half of that: about 4.1 million tonnes or around 9kg of food from every home, every week.

But for the first time, we know exactly what we waste, how it is wasted, and where it goes.

Researchers from the University of South Australia have traced the cycle of food waste in a three-year study looking at the economic, environmental and psychological modelling of food waste.

A new land management tool using Aboriginal knowledge

Ngan’gi speakers know it’s time to look for freshwater crocodile eggs when the red kapok trees near the Northern Territory’s Daly River burst into flower.

This can occur at a different time each year, but the environmental link is solid.

A Darwin-based scientist has converted this link and other intimate Aboriginal knowledge of Australia’s landscape into an environmental management tool.

CSIRO’s Emma Woodward worked with Aboriginal elders as part of the Tropical Rivers and Coastal Knowledge research program to develop six seasonal calendars from six different language groups from the Northern Territory and Western Australia. [click to continue…]

Genetics can be used to shape plants underground so they absorb water better

Recent discoveries by a University of Queensland agricultural scientist provide the basis for custom designing plant roots. Her discovery is already being used by plant breeders to develop drought-resistant sorghum crops. [click to continue…]
