Humanity is rapidly depleting a third of the world's largest groundwater aquifers, with the top three most stressed groundwater basins in the political hotspots of the Middle East, the border region between India and Pakistan, and the Murzuk-Djado Basin in northern Africa.

Making matters worse, researchers say in a pair of new studies, we don't know how much water is left in these massive aquifers '€” which water resources scientists often refer to as Earth's water savings accounts. ...

This year's record droughts in California and Brazil are just the latest reminder of the growing water crisis. Today, 25 percent of the world's largest cities are experiencing over-stressed water supplies. Almost 1 billion people face water shortages, and in 15 years, the global demand for reliable water sources will likely exceed supply by 40 percent.

 Reversing this trend will require looking beyond traditional solutions—and building alliances with unlikely partners. ... Read more about The Nature Conservancy: Follow this Urban Water Blueprint

The dwindling supply of clean water available to growing urban areas isn't an abstract problem for Atlanta Mayor Kasim Reed.

He's seen opposing financial pressures and concerns about sustainable water sources play out first hand in the sprawling metro area now home to some 6 million people.

"The city of Atlanta has a $3 billion to $4 billion capital program around water and sewer," Reed recently explained at the GreenBiz VERGE 2014 conference in San Francisco. "We had terrible water wars in Atlanta between Georgia, Alabama and Florida." ... Read more about How much will it cost to turn the tide of the urban water crisis?

As the demand for freshwater and energy increases in San Diego County and Northern Baja, the fresh water supply continues to shrink while energy generation remains heavily dependent on fossil fuels. Due to these opposing trends in supply and demand, it becomes increasingly imperative to identify solutions that move these communities to their preferred state in which they are largely reliant on renewable energy and use water sustainably. Large-scale energy solutions include wind power, one of the must abundant sources of energy in these regions. ... Read more about Geodesign Session 5 Road Map

There are several different directions that our planet can take to address the ever growing need for water and energy. This will involve integrating technologies of a large and small scale into our grid and into our homes as well. There are two main technologies in which to address large scale water sustainability: desalination and ‘pure water’ recycling. As the California dries out, it is increasingly important to adopt proven strategies to maintain the current standard of living. ...
