VITAL WATER GRAPHICS. An Overview of the State of the World’s Fresh and Marine Waters

PNUE

Présentation
The terms of the equation remain simple : for the next few decades, given the volume of available water, and under the present circumstances, will it be possible to provide enough water to a population forecast to be at least 9 billion by 2050 (according to the medium hypothesis proposed by the United Nations) using a volume which will be roughly the same as it is now ?
In the context of stress and scarcity, the challenge will be to find creative ways to manage water resources without emphasizing already existing disputes and conflicts. This is raising important questions : is it reasonable to envisage more long distance water transfer without threatening water reserves and harming environmental balance ? Which are the countries and regions that will suffer the most due to lack of water ? And in which countries will an important part of the population still have to wait for decades before being supplied with improved water ?
This 2008 update of the ‘Vital Water Graphics’ is aimed at giving an overview of the state of water resources in the world and providing answers to these important questions.
