WASHINGTON – More than one billion urban residents will face serious water shortages by 2050 as climate change worsens effects of urbanization, with Indian cities among the worst hit, a study said Monday.

The shortage threatens sanitation in some of the world's fastest-growing cities but also poses risks for wildlife if cities pump in water from outside, said the article in the Proceedings of the National Academy of Sciences.

The study found that under current urbanization trends, by mid-century some 993 million city dwellers will live with less than 100 liters (26 gallons) each day of water each -- roughly the amount that fills a personal bathtub -- which authors considered the daily minimum.

Adding on the impact of climate change, an additional 100 million people will lack what they need for drinking, cooking, cleaning, bathing and toilet use.

"Don't take the numbers as destiny. They're a sign of a challenge," said lead author Rob McDonald of The Nature Conservancy, a private environmental group based near Washington.

"There are solutions to getting those billion people water. It's just a sign that a lot more investment is going to be needed, either in infrastructure or in water use efficiency," he said.

Currently, around 150 million people fall below the 100-liter threshold for daily water use. The average American has 376 liters delivered a day, although actual use varies widely depending on region, McDonald said.

China, according to their own documentation, has a natural water supply at present that is only 50% clean enough for industrial purposes, let alone drink or bathe ones child in


so guess what continent they will be going to

to find willing "heads of state" to sell off their water rights while the people dehydrate?
 
We have oceans n means of de-salting the water n making it drinkable......lets try that out......



In the Spirit of Sankofa,




.......Great idea,

Can You Make Seawater Drinkable?

A number of technologies have been developed for desalination, including reverse osmosis (RO), distillation, electrodialysis, and vacuum freezing. So why is seawater such an attractive water resource?


Reverse Osmosis
(1) (Desalination) The process of removing salts from water using a membrane. With reverse osmosis, the product water passes through a fine membrane that the salts are unable to pass through, while the salt waste (brine) is removed and disposed. This process differs from electrodialysis, where the salts are extracted from the feedwater by using a membrane with an electrical current to separate the ions. The positive ions go through one membrane, while the negative ions flow through a different membrane, leaving the end product of freshwater. (2) (Water Quality) An advanced method of water or wastewater treatment that relies on a semi-permeable membrane to separate waters from pollutants. An external force is used to reverse the normal osmotic process resulting in the solvent moving from a solution of higher concentration to one of lower concentration.


And, of all the Earth's water, 97 percent is salt water, only 1 percent is fresh water available for humans to drink, and 2 percent is frozen. Of the more than 7,500 desalination plants in operation worldwide, 60% are located in the Middle East. The world's largest plant in Saudi Arabia produces 128 MGD of desalted water. In contrast, 12% of the world's capacity is produced in the Americas, with most of the plants located in the Caribbean and Florida.

To date, only a limited number of desalination plants have been built along the California coast, primarily because the cost of desalination is generally higher than the costs of other water supply alternatives available in California (e.g., water transfers and groundwater pumping). However, as drought conditions occur and concern over water availability increases, desalination projects are being proposed at numerous locations in the state. Desalination costs are decreasing as technology improves and more plants are built. Today there are more than 15,000 desalination plants in 120 countries.

The desalination market is forecast to grow more than $70 billion in the next 20 years. About half of the world's desalted water is produced with heat to distill fresh water from seawater.

Peace In,
 
I remember hearing on the news or reading about private folk / businesses buying up world water resources.

That was problee massa 'nem buy'n all da watah up and you know he gonna let us have some 'cause he let us have some now.

What would we do if'n massa wasn't so smart and kind to us.

Love You!

:heart:
