There are huge holes in the governance of Nairobi river and city's waste which means the river's condition has deteriorated.
Wastewater reuse suffers from a perception problem.
Pumping high-pressure fluid into fault lines causes them to slowly slip, increasing the pressure on more distant rock and inducing earthquakes far away.
Just as America's highways, sewage systems and water pipes need fixing, so does the growing gap between rich and poor. Trump and the Democrats could use that money to address both.
Currently, all the value in sewage sludge is literally being flushed down the toilet.
Scientists are finding ways to generate something useful from the pollution in our environment.
City fringe foodbowls supply much of our fresh produce and can increase climate resilience by making better use of wastewater and organic waste. A new roadmap outlines how to protect these foodbowls.
The 'used water' that flows from our showers, dishwashers and toilets isn't a waste to engineers – it contains valuable materials. The challenge is recovering them and turning them into products.
Some of the things we discard - like urine - can actually be useful resources.
New research shows that injecting wastewater deep underground can cause earthquakes far from the injection site. It also raises questions about which rock layers are the safest injection targets.
Food systems must be transformed to produce more nutritious food with a lower environmental footprint.
In an increasingly urban world, trees can make a major difference. One study found that, for every dollar invested in planting, megacities saw a $2.50 return on their investment.
World Water Day shines a light on the importance of safe, clean drinking water, but a new report finds Canada's freshwater systems are under stress.
Perth, unlike Cape Town, faces no prospect of its tapwater running out. But other problems lurk beneath the surface, as the city's drying climate puts increasing pressure on irrigation and wetlands.
Cities all over the world are facing growing challenges to provide clean, reliable water. And many of the fixes, such as desalination plants, have a huge carbon footprint.
The experiences of other countries can provide valuable lessons for Cape Town on how to better cope with its water crisis.
Once unleashed, glitter gets everywhere – not just in your house, but into the environment. Time to call a halt to the glitter explosion.
With frigid temperatures and snow in the forecast, slippery roads can't be far behind. Salt keeps roads safe, but it's harmful to aquatic environments.
The UK water infrastructure needs rethinking with the increasing population demands and the contaminants found in our water.
