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.
Dry regions will get drier and wet regions wetter as the climate changes. How quickly? Quicker than we thought, unfortunately.
A staggering 85% of the world’s chalk streams are found in England.
The presence of a vulnerable species in Ekor Waterfalls, Nigeria, is a signal that the area could support other rare or threatened species.
Australia’s southwest is a biodiversity hotspot - and it’s also a climate change hotspot. Something has to give.
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.
The growing frequency of climate extremes affected human health and caused wide-scale damages to the ecosystems that people depend upon, including agriculture, fisheries and freshwater.
Chemicals in drugs can be excreted unchanged, infiltrating waterways via sewage and effluent.
The lives of one in ten of Earth’s species are connected to lakes and their tributaries.
Canada has 20 per cent of the world’s freshwater reserves and nine per cent of the world’s renewable freshwater resources. However, there is an urgent need for better freshwater governance in Canada.
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.
