It's long been known that our diet choices help determine our carbon footprint. But do you know which of your favourite foods are the most water-hungry?
Buybacks by open tenders were a successful, cost-effective way of returning water to the Murray-Darling Basin. They should never have been abandoned.
The nutritional, financial and environmental cost of an average family's weekly food waste is shocking. It equates to five adult meals, 143 showers, $18 and 23 kg of CO2.
South Africa's independent regulators have failed. Instead of introducing new ones, alternatives need to be found.
A 2006 Supreme Court ruling created widespread confusion about which wetlands and other waters are federally protected. The Trump administration's latest action isn't likely to clear things up.
Combining aquaculture and hydroponics, aquaponics unearths value in "waste" flows and re-routes them back into the economy. It's an inspiring example of how a circular-economy business model can work.
Carbon dioxide makes up less than one-twentieth of 1% of Earth's atmosphere. How does this relatively scarce gas control Earth's thermostat?
Peruvian glaciers have shrunk by 25% since 1987, causing water shortages in rural villages. But ancient technology could help manage this precious resource.
Climate change threatens the water supply of nations around the world. But it's difficult to measure whether a region has sufficient water to satisfy the people who live there. Could satellites help?
New research forecasts that climate change will make multiyear stretches with low snow levels more common across western North America – bad news for water managers, farmers, foresters and skiers.
Millions of Americans rely on groundwater for their lives and livelihoods, but regulation is piecemeal. A new study maps groundwater wells nationwide and finds that they are drilling steadily deeper.
Hitting the Paris targets will go a long way to securing Melbourne's water supply against future pressure.
What exactly is inside those red fire extinguisher canisters, and does it work better than water?
Western states adopted a 7-year plan in May 2019 to manage low water levels in the Colorado River. Now they need to look farther ahead and accept that there will be less water far into the future.
Flint's highest recorded lead levels were typical for water systems that report problems. What's more, a number of cities haven't reported their lead issues.
Imagining how to increase water managers’ empathy for others in a holistic way is critical for our human and planetary future.
Cold water shock explained.
The Murray-Darling Basin might not survive future climate change shocks without changes to the plan.
Over the past 20 years, Great Lakes water levels have gone from sustained multiyear lows to multiyear highs. Climate change is accelerating the transition between dry phases and wet phases.
