Any plan to dam or extract water from some of Australia’s last wild rivers must carefully consider the consequences. Prawn, mud crab and barramundi fisheries could suffer in the Gulf of Carpentaria.

Saltwater intrusion is bad for human health, ecosystems, crops and infrastructure. Here’s how seawater can move inland, and why climate change is making this phenomenon more frequent and severe.
The Peach Blossom Jellyfish is an invasive species in Canada, and a lack of data is hampering efforts to control populations.
We’ve become so good at using the Earth’s resources we’re endangering the systems we rely on.
Researchers even found textile fibres in very remote lakes with limited human presence.
We’ve blown past the safe and just limit for vital Earth systems, from climate change to the biosphere and the use of fertilisers and freshwater. For humans to thrive means living in safe limits
Although it has been considerably less studied than other environmental problems, salinization presents major challenges for biodiversity in freshwater and coastal areas.
Aquifers are highly prevalent across Africa – but they’re not always going to be usable.
In 1776, with a population of 2.5 million, few imagined that within two centuries, the U.S. would become the dominant superpower. It’s not inconceivable that Canada could do the same by 2223.
Urban infrastructure was designed to take stormwater out to the ocean quickly. Now, California needs that precious water.
A new survey has revealed an alarming deterioration in the health of the River Thames ecosystem – but some of the recorded changes may be the result of a cleaner river.
Governments, industrial and development companies and scientists need to take a leading role in finding strategic solutions to the cumulative threats impacting our freshwater ecosystems.
While we know how global changes in freshwater pose risks to humans and ecosystems, we know less about how people and ecosystems will respond to these global freshwater challenges.
Most of the flooded communities are Indigenous and rely on subsistence hunting that residents would normally be doing right now. Recovering from the damage will make that harder.
Migratory fish populations have collapsed worldwide in the last 50 years.
Sandfish keep the rivers clean and the food web balanced but their numbers are declining. Farmers are helping to lift these numbers.
A new study of dairying in Canterbury shows previous estimates vastly underestimate the impact of intensive farming. A 12-fold reduction in cow numbers could be needed to meet safe water standards.
Nigeria should urgently protect three freshwater ecosystems as these undisturbed environments are becoming rare globally.
Our planet’s invaluable natural store of freshwater is woefully neglected.
The Nigerian government must do more to combat increasing plastic pollution in the country.
