Researchers at Cornell University have developed nanoscale sensors that help breeders select water-efficient crops, enhancing their resilience against droughts caused by climate change.

Forecasts have been pointing out for years that water scarcity will become a problem. Here's one start-up's smart solution.

Can you have hydro storage without water? A British start-up is looking to open up the potential of pumped hydro renewable energy storage.

“Water, water everywhere, but not a drop to drink” — water scarcity doesn’t always mean a lack of water. Sometimes, it just needs to be cleaned.

Much of the world is wracked by water scarcity. Can high tech nano-engineering provide surprisingly simple and cheap solutions?

Many innovative designs have experimented with producing clean water from contaminated or salt water. A new approach takes inspiration from mangrove trees.

Solar thermal water heaters have been around for a while, but their expensive and scale means they're only available to wealthy homeowners. A new flat-pack version wants to change that.

Water security is increasingly becoming one of the fundamental issues of the 21st century, especially for states in the dryer and more arid regions of the world. With water forming the basis of all life, some nations are adopting increasingly radical solutions to ensure a fresh supply of water. For example, states such as the

Passive water harvesting technologies offer clear advantages in terms of power use, but are often limited in output. A new design aims to push them to their limits.
