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.
When humans eat fish, mussels and other foods containing antibiotics, the residual antibiotics may cause bacterial pathogens to become resistant.
Covering the state’s canals with solar panels would reduce evaporation of precious water and help meet renewable energy goals – all while saving money.
Saving the Great Barrier Reef is not about throwing money at it – what matters is how the dollars are spent.
Rivers are among the most embattled ecosystems on Earth. Researchers are testing a new, inexpensive way to study river health by using eDNA to count the species that rivers harbor.
New research shows how fracking could pose a threat to surface water quality, with consequences for human and environmental health.
The remarkably resilient structure is in good health, for now. But work is needed to ensure it is preserved for future generations.
The US has one of the highest groundwater use rates in the world. When wells run dry, households may opt to conserve water, find new sources or sell and move.
New Zealanders pay the costs of poor environmental and infrastructural governance, but have little opportunity to influence policy in the first place. Here’s how that could change.
New Zealand spends about $500m on environmental research each year, but fails to invest systematically in monitoring programmes to track the changing environment.
A long-awaited NZ$700 million package to clean up New Zealand’s rivers and lakes has disappointed some of the government’s expert advisers – especially a delay on setting clear pollution limits.
A new report on New Zealand’s lakes and rivers confirms that many freshwater ecosystems are in decline and warns that climate change will exacerbate existing threats.
Floods will undoubtably wash pollutants into water reservoirs. Are we prepared enough to protect our drinking water?
If you want to swim in the Yarra River, you can check the water quality to see if it’s safe. If you want to swim in the Nepean River, you can’t – and that’s a problem.
Damage to water supply infrastructure and catchments during and after bushfires inhibits the treatment processes that normally make our water safe to drink.
The New Zealand government’s decision to partner the farming sector to encourage voluntary reductions in farm emissions failed to acknowledge that agricultural emissions also affect water quality.
Few feel the pain of the Great Barrier Reef’s decline more acutely than the scientists trying to save it. Ahead of a UN climate summit, two researchers write of their grief, and hope.
We all know that climate change is hurting the Great Barrier Reef. But scores of other less-publicised threats also threaten the future of the natural wonder.
A proposed plan to clean up New Zealand’s waterways draws clear limits on the expansion of dairy farming and irrigation, as well as on the use of nitrogen fertiliser in some key areas.
Many remote communities in Australia’s north rely on bore water. But a new microbiology analysis suggests that the chemistry of untreated water can allow disease-causing bacteria to grow unchecked.
