Ripple effect: How public attitudes can shift governments toward sustainable, and resilient, water systems

The results of a new study are clear: resilient water governance systems are effective and enjoy strong public support. The time is now to build resilience into our global water systems.

‘Forever contaminant’ road salts pose an icy dilemma: Do we protect drivers or our fresh water?

Increasing awareness of the dangers ‘forever chemical’ road salts pose to our fresh water systems highlights the urgent importance of finding new approaches to de-icing our roads.

What is seawater intrusion? A hydrogeologist explains the shifting balance between fresh and salt water at the coast

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.

It’s not just climate – we’ve already breached most of the Earth’s limits. A safer, fairer future means treading lightly

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
Roads require de-icing strategies in northern regions, but this practice has negative effects on aquatic biodiversity.

Freshwater ecosystems are becoming increasingly salty. Here’s why this is a concern

Although it has been considerably less studied than other environmental problems, salinization presents major challenges for biodiversity in freshwater and coastal areas.

Canada, a superpower? Here’s how the country might one day fit the bill

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.

How California could save up its rain to ease future droughts — instead of watching epic atmospheric river rainfall drain into the Pacific

Urban infrastructure was designed to take stormwater out to the ocean quickly. Now, California needs that precious water.

The use of natural outdoor laboratories can reduce threats to freshwater biodiversity

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.
