"STOCKHOLM — Population growth and water stress are driving Earth to a food and environmental crunch that only better farming techniques and smarter use of the ecosystem will avert, a UN report issued on Monday said."

"The number of humans is expected to rise from seven billion in 2011 to at least nine billion by 2050, boosting demands for water that are already extreme in many countries and set to worsen through global warming.

'Currently, 1.6 billion people live in areas of physical water scarcity and this could easily grow to two billion soon if we stay on the present course,' according to the report."

AFP had the story August 21, 2011.
