New research shows how river flows in the once-mighty Murrumbidgee have dwindled over time, leaving the floodplain high and dry. But the main culprit is not climate change and we can fix it.
Australia now has more than enough evidence that proposals to build big dams consistently underestimate both the construction costs and the harm they do.
It’s easier to steal another seabird’s meal than catch your own fish. But this behaviour by skuas, frigatebirds and gulls is contributing to the spread of lethal avian influenza
For the second time in five years, millions of fish suffocated in the Darling River. This was not a natural disaster – it’s our doing
Climate change shouldn’t be used as a “get out-of jail free” card to excuse bad decision-making and poor planning decisions.
Lake Eyre Basin contains one of the few pristine river systems left in the world. But new research shows oil and gas activity is extending its tentacles into these fragile environments.
Federal Labor has pledged to deliver the Murray Darling Basin Plan. But a new report casts serious doubt on that promise.
Australian wildlife can generally cope with drought, but they’re not prepared for the combination of people, introduced animals, and no water.
A dozen leading researchers have issued an urgent call to action for the Murray-Darling Basin, arguing that the billions spent on water-efficient irrigation have done little for the rivers’ health.
Freshwater fish are declining everywhere, in part thanks to dam-building. But we can have both.
Wetlands and rivers need water – not least in the case of Australia’s biggest river system, the Murray-Darling Basin, which has been the target of an “environmental watering” plan designed to preserve…
Australia is famous for its natural beauty: the Great Barrier Reef, Uluru, Kakadu, the Kimberley. But what about the places almost no one goes? We asked ecologists, biologists and wildlife researchers…
Yesterday, Minister for the Environment Tony Burke signed the Murray-Darling Basin Plan into law, after the Murray-Darling Basin Authority had made the final changes he requested. One hurdle remains. The…
The history of our development of the Murray-Darling Basin is one of constraining and constricting its rivers’ flows. Many of the basin’s floods are now captured in dams for later constrained release to…
The release of the Draft Murray-Darling Basin plan earlier today, and the announcement that 2,750 gigalitres would be returned to the environment, was followed by predictable outrage. Irrigators said that…
There are few issues as divisive in eastern Australia as duck hunting. And 2011 has been one of the most vitriolic seasons yet. The season opened in Victoria with news that a protester had been shot in…
