2013 JUN 16 (VerticalNews) -- By a News Reporter-Staff News Editor at VerticalNews Health & Science -- A conference of 500 leading water scientists from around the world issued a stark warning that, without major reforms, "in the short span of one or two generations, the majority of the 9 billion people on Earth will be living under the handicap of severe pressure on fresh water, an absolutely essential natural resource for which there is no substitute. This handicap will be self-inflicted and is, we believe, entirely avoidable."

The scientists bluntly pointed to chronic underlying problems led by mismanagement and sent a prescription to policy makers in a 1,000-word declaration issued at the end of a four-day meeting in Bonn, Germany, "Water in the Anthropocene," organized by the Global Water System Project and detailed in a pre-conference release: http://www.eurekalert.org/pub_releases/2013-05/gwsp-sig051413.php.

The full text of The Bonn Declaration:

In the short span of one or two generations, the majority of the 9 billion people on Earth will be living under the handicap of severe pressure on fresh water, an absolutely essential natural resource for which there is no substitute. This handicap will be self-inflicted and is, we believe, entirely avoidable.

After years of observations and a decade of integrative research convened under the Earth System Science Partnership (ESSP) and other initiatives, water scientists are more than ever convinced that fresh watersystems across the planet are in a precarious state.

Mismanagement, overuse and climate change pose long-term threats to human well-being, and evaluating and responding to those threats constitutes a major challenge to water researchers and managers alike. Countless millions of individual local human actions add up and reverberate into larger regional, continental and global changes that have drastically changed water flows and storage, impaired water quality, and damaged aquatic ecosystems.

Human activity thus plays a central role in the behavior of the global water system.

Since 2004, the Global Water System Project (GWSP) has spearheaded a broad research agenda and new ways of thinking about water as a complex global system, emphasizing the links that bind its natural and human components. Research carried out by GWSP and its partners has produced several important results that inform a better global understanding of fresh water today.

Humans are a key feature of the global water system, influencing prodigious quantities of water: stored in reservoirs, taken from rivers and groundwater and lost in various ways. Additional deterioration through pollution, now detectable on a global scale, further limits an already-stressed resource base, and negatively affects the health of aquatic life forms and human beings.

At a time of impending water challenges, it remains a struggle to secure the basic environmental and social observations needed to obtain an accurate picture of the state of the resource. We need to know about the availability, condition and use of water as part of a global system through sustained environmental surveillance. History teaches us that failure to obtain this basic information will be costly and dangerous.

Humans typically achieve water security through short-term and often costly engineering solutions, which can create long-lived impacts on social-ecological systems. Faced with a choice of water for short-term economic gain or for the more general health of aquatic ecosystems, society overwhelmingly chooses development, often with deleterious consequences on the very water systems that provide the resource.

Traditional approaches to development are counterproductive, destroying the services that healthy watersystems provide,
