(BBC)-If you want to induce mental meltdown, the statistics of the worsening global water crisis are a surefire winner.
Two-fifths of the world's people already face serious shortages, and water-borne diseases fill half its hospital beds. news.bbc.co.uk...
The present is dire: the future looks so grim it must be entirely unmanageable.
Cut it how you will, the picture that emerges from today's data and tomorrow's forecasts is so complex and appalling it can leave you feeling powerless. news.bbc.co.uk...
The world cannot increase its supply of fresh water: all it can do is change the way it uses it.

(Panda.org)-Water shortages in Australia highlighted on World Environment day
Sydney, Australia – Australian cities won't be sustainable in the long term if they continue to waste water at current levels, says WWF-Australia on World Environment Day, whose theme this year is focused on "green cities".

“Water shortages in Australian cities are evidence that our urban centres are on borrowed time,” said Dr Ray Nias, WWF-Australia's Director for Conservation.

New water restrictions and dams at record-low levels show exactly how the country's cities are now running on empty.
“On World Environment Day city-dwellers are being urged to do everything they can to look after the rivers, aquifers, and wetlands that sustain them," Nias added.

(Gemni.org)-Increasing human demands for water and unsustainable rates of water withdrawal are likely to worsen water shortages. Other factors also have the potential to affect long-term water availability.
40% of the world will live in water-scarce regions by 2025.(5) Factors likely to contribute to these predicted water shortages include population growth and unsustainable rates of water withdrawal. The United Nations currently estimates global annual population growth at 1.2%, which translates to an increase of 77 million people per year.(6)

In the past, as demand for water has increased, society’s focus has been on addressing this demand through increases in supply. However, this solution is becoming increasingly difficult and costly and may soon be infeasible in many areas.

Inadequate supplies of clean freshwater contribute to a broad range of public health issues, especially in the non-industrial nations and some developing nations. Human health can be affected by freshwater problems ranging from contamination of municipal water supply sources to pollution of water bodies used for fishing or recreation. Pathogens that cause acute illness and disease, or chemicals that can be carcinogens in high concentrations, can affect drinking water supplies. Non-industrial and developing nations face the most serious threats to human health from inadequate freshwater supplies. Various sources estimate that 1 to 1.5 billion people lack access to safe drinking water, 2 to 3 billion people lack access to proper sanitation, and 14,000 to 30,000 people die each day from water-borne illnesses.(15) These astonishing numbers represent a significant challenge for individuals, governments, and businesses in coming decades.

(BBC)-Water shortages set to grow
In 1999 the United Nations Environment Programme (UNEP) reported that 200 scientists in 50 countries had identified water shortage as one of the two most worrying problems for the new millennium (the other was global warming). news.bbc.co.uk...
Seventy percent of the water used worldwide is used for agriculture.
Much more will be needed if we are to feed the world's growing population - predicted to rise from about six billion today to 8.9 billion by 2050.
And consumption will soar further as more people expect Western-style lifestyles and diets - one kilogram of grain-fed beef needs at least 15 cubic metres of water, while a kilo of cereals needs only up to three cubic metres.
