Climate change endangers half the world’s groundwater supply

Climate change endangers half the world’s groundwater supply

Climate change today will effect the water supply for hundreds—possibly thousands—of years. Humans exist on a short leash. A person can only last around three days without drinking water. Put that way, human life is absurdly fragile; plenty of other organisms can go far longer. Just think of your houseplant. To make matters more precarious, that essential substance is growing harder to come by. You’ve heard about this: climate change … [more…]

New research has discovered how plant roots sense the availability of moisture in soil and then adapt their shape to optimise acquisition of water.

The discovery could enable crops to be bred which are more adaptive to changes in climate conditions, such as water scarcity, and help ensure food security in the future.

These findings, … [more…]

A permanent solution to California’s water woes — seawater

Workers move a pipe in front of the 2000 pressure vessels that will be used to convert seawater into fresh water through reverse osmosis in the western hemisphere’s largest desalination plant in Carlsbad (San Diego County). Long ignored as too costly and environmentally dubious, desalination is returning to the public discussion of how to address California’s water woes. Photo: Gregory Bull / Associated Press 2015

Water is one of the most valuable resources on Earth. It covers over two thirds of the planet’s surface, makes up around 70% of the human body and is essential for life. For many people a consistent supply of clean, safe water is on tap. But for many others … [more…]

Where’s The Fresh Water Going?

Freshwater Is Disappearing; Can Technology Save Us?

Fresh water is the most important resource for human life on earth.

People can survive far longer without food than without water, and virtually all of our food sources require fresh water to grow or create.
