‘Growing world population will cause a “perfect storm” of food, energy and water shortages by 2030′. That is what a UK Government chief scientist told attendees at the Sustainable Development conference in London yesterday. Prof. Beddington told the group that demand for food and energy will jump 50% by 2030 and for fresh water by 30%, as the population tops 8.3 billion.
Despite this, investment in water deals represented just 1.8% of the total investment in the Clean Technology area in 2008. There are number of reasons for this and also signs that this is changing.

Having grown up in the beautiful Chicagoland area in the 80’s my water needs were strictly as follows: Need #1: Water from hose to power clown-face sprinkler, fill water balloons, and hose off muddy dirt-bike/self, Need #2: Water from faucet to occasionally brush teeth and occasionally make Hi-C or Tang, Need #3: Water from shower to occasionally bathe. It was a simpler time, and I was a kid. To me and most other kids (adults?) in the 80’s water was simply there, always on the ready for any and all of the above dalliances.
The days of water-logged frivolity are over. We now live in a time where many parts of the world face water shortages, limited access to safe, clean drinking water, an ever-diminishing groundwater supply, and a growing number of water-related disease and death.
In fact, just last week, motivated by three years of water shortages in California, California Governor Arnold Schwarzenegger declared a state of emergency which may be followed by water rationing measures.
As a result of the myriad of water emergencies that the world faces I have put together a short-list of the 5 world-saving water solutions that offer hope for the future of our water, and therefore our existence.

As the world approaches peak water, technology to harvest freshwater from non-potable sources becomes increasingly important. Researchers at Yale University have recently developed such desalination technology using the power of osmosis.
