Bonn Declaration issued by 500 scientists at 'Water in the Anthropocene' conference

A conference of 500 leading water scientists from around the world today 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 water systems 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 water systems provide, such as flood protection, habitat for fisheries and pollution control. Loss of these services will adversely affect current and future generations.

Sustainable development requires both technological and institutional innovation. At present, the formulation of effective institutions for the management of water lags behind engineering technologies in many regions.

Research from the GWSP and elsewhere confirms that current increases in the use of water and impairment of the water system are on an unsustainable trajectory. However, current scientific knowledge cannot predict exactly how or precisely when a planetary-scale boundary will be breached. Such a tipping point could trigger irreversible change with potentially catastrophic consequences.

The existing focus on water supply, sanitation and hygiene has delivered undoubted benefits to people around the world, but equally, we need to consider wider Sustainable Development Goals in the context of the global water system. Ecosystem-based sustainable water management, a pressing need that was reaffirmed at the Rio+20 Earth Summit, requires that solving water problems must be a joint obligation of environmental scientists, social scientists, engineers, policy-makers, and a wide range of stakeholders.

These realities motivate the water community assembled in Bonn for the Global Water System Project Conference "Water in the Anthropocene" to make a set of core recommendations to institutions and individuals focused on science, governance, management and decision-making relevant to water resources on earth. Given the development imperatives associated with all natural resources at the dawn of the 21st century, we urge a united front to form a strategic partnership of scientists, public stakeholders, decision-makers and the private sector. This partnership should develop a broad, community-consensus blueprint for a reality-based, multi-perspective, and multi-scale knowledge-to-action water agenda, based on these recommendations:

1) Make a renewed commitment to adopt a multi-scale and interdisciplinary approach to water science in order to understand the complex and interlinked nature of the global water system and how it may change now and in future.

2) Execute state-of-the-art synthesis studies of knowledge about fresh water that can inform risk assessments and be used to develop strategies to better promote the protection of water systems.

3) Train the next generation of water scientists and practitioners in global change research and management, making use of cross-scale analysis and integrated system design.

4) Expand monitoring, through traditional land-based environmental observation networks and state-of-the-art earth-observation satellite systems, to provide detailed observations of water system state.

5) Consider ecosystem-based alternatives to costly structural solutions for climate proofing, such that the design of the built environment in future includes both traditional and green infrastructure.

6) Stimulate innovation in water institutions, with a balance of technical- and governance-based solutions and taking heed of value systems and equity. A failure to adopt a more inclusive approach will make it impossible to design effective green growth strategies or policies.

The recommendations above, taken collectively, can constitute the centrepiece of a blueprint to promote the adoption of science-based evidence into the formulation of goals for sustainable development. Stewardship requires balancing the needs of humankind and the needs of nature through the protection of ecosystems and the services that they provide. Without such a design framework, we anticipate highly fragmented decision-making and the persistence of maladaptive approaches to water management.

Background

Water in the Anthropocene

A new geologic epoch, "The Anthropocene," is characterized by humanity's growing dominance of Earth's environment and a planetary transformation as profound as the last epoch-defining event -- the retreat of the glaciers 11, 500 years ago.

Among examples of humans' planet-altering imprint on the world:

  • Humanity uses an area the size of South America to grow its crops and an area the size of Africa for raising livestock
  • Due to groundwater and hydrocarbon pumping in low lying coastal areas, two-thirds of major river deltas are sinking, some of them at a rate four times faster on average than global sea level is rising
  • More rock and sediment is now moved by human activities such as shoreline in-filling, damming and mining than by the natural erosive forces of ice, wind and water combined
  • Many river floods today have links to human activities, including the Indus flood of 2010 (which killed 2,000 people), and the Bangkok flood of 2011 (815 deaths)
  • On average, humanity has built one large dam every day for the last 130 years. Tens of thousands of large dams now distort natural river flows to which ecosystems and aquatic life adapted over millennia
  • Drainage of wetlands destroys their capacity to ease floods-a free service of nature expensive to replace
  • Evaporation from poorly-managed irrigation renders many of the world's rivers dry -- no water, no life. And so, little by little, tens of thousands of species edge closer to extinction every day

Panama canal watershed offers test bed for ecosystem services

More than 13,000 ships per year, carrying more than 284 million tons of cargo, transit the Panama Canal each year, generating roughly $1.8 billion dollars in toll fees for the Panama Canal Authority. Each time a ship passes through, more than 55 million gallons of water are used from Gatun Lake, which is also a source of water for the 2 million people living in the isthmus.

However, the advent of very large "super" cargo ships, now more than 20 percent of the ships at sea, has demanded change. The Panama Canal is being expanded to create channels and locks three times larger than at present, leaving the authority to consider how best to meet the increased demand for water. One proposed measure is the reforestation of the watershed.

To help planners and policy makers understand the effects of reforestation, ASU scientists Silvio Simonit and Charles Perrings studied the effects of reforestation on a 'bundle' of ecosystem services: dry-season water flows, carbon sequestration, timber and livestock production.

Published this week in Proceedings of the National Academy of Sciences (PNAS), their study "Bundling ecosystem services in the Panama Canal Watershed" examines precipitation, topography, vegetation, and soil characteristics to model on-site and off-site effects of several reforestation options.

"The Panama Canal watershed is currently being reforested to protect the dry-season flows needed for canal operations. We find however that reforestation does not necessarily increase water supply, but does increase carbon sequestration and timber production," said Simonit. "Our research provides an insight into the importance of understanding the spatial distribution of the costs and benefits of jointly produced services." Simonit, a member of ASU's Ecoservices Group co-directed by Perrings, is part of a collaborative research partnership between ASU and the Smithsonian Tropical Research Institute (STRI). He is also a post-doctoral fellow on the National Science Foundation-funded research coordination network: Biodiversity and Ecosystem Services Training Network (BESTNet).

Simonit and Perrings found that only 37 percent of the currently forested area positively impacts dry-season water flows, offering up roughly 37.2 million cubic meters of seasonal flow (equivalent to US $16.37 million in revenue to the Panama Canal Authority).

In parts of the watershed not currently under forest, they found that reforestation of areas with high precipitation rates, flat terrain, and soil types with high potential infiltration would enhance dry-season flows. However, they note that these conditions exist in less than 5 percent of watershed not currently under forest.

"Water supply is, however, only one amongst many ecosystem services affected by reforestation of the watershed," said Perrings, a professor in the School of Life Sciences in ASU's College of Liberal Arts and Sciences. "And the balance between services depends on the type of reforestation undertaken." Accordingly, the duo investigated two reforestation scenarios: natural forest regeneration and teak plantation.

"We found that if all existing grasslands were allowed to regenerate as natural forest, there would be a reduction in dry-season flows across the watershed of 8.4 percent, compared to 11.1 percent if reforestation took the form of teak plantations." In both cases, these conditions potentially pose a problem for the Panama Canal Authority. Even with water-saving advances in the new locks, the canal is expected to need 14 percent more water when the expansion takes full effect, and other options for securing dry-season flows are not cost-free. However, the Panama Canal Authority is not the only beneficiary of the watershed, and water is not the only ecosystem service supplied. "Both natural forest and teak plantations offer benefits in the form of carbon sequestration and timber products, among other things, and these should be weighed against any water losses," said Perrings.

According to their study, water losses from "natural" forest regeneration would be compensated by the value of carbon sequestration in 59.6 percent of the converted area at current carbon prices. On the other hand, reforestation of existing grassland with teak (under sustainable forest management) would generate gains sufficient to offset the hydrological losses in all converted areas, regardless of the value of carbon.

The authors note that their study does not consider the value of land cover as habitat for wild fauna and flora. However, they say their results could help canal planners prioritize reforestation efforts. Knowing what to plant and where can reduce the negative impact of forests on dry season water flows, while providing other important ecosystem services.

Yahoo Acquires Gaming Infrastructure Startup PlayerScale ...

Another day, another acquisition by Yahoo.

Yahoo said this morning it?s acquired PlayerScale, a California-based startup that makes software infrastructure for cross-platform gaming. Financial details haven?t been disclosed.

PlayerScale, which was self-funded and cash-flow positive as of this past January, was founded in 2009. According to a VentureBeat article also from January, the company had a staff of 14. It?s not clear yet how many staff are involved and will be joining Yahoo ? we?ve reached out for details and will update this with any information we receive. Update: Yahoo tells us that 7 people from PlayerScale are joining Yahoo as part of the transaction.

The four-year-old PlayerScale says its platform now has more than 150 million players, which marks significant growth from just this past January when our own Anthony Ha reported the platform had crossed the 100 million user line. For now this does not look like a straight acqui-hire situation, as both Yahoo and PlayerScale say the gaming platform will remain active post-acquisition and continue to be developed.

Here is a statement provided by Yahoo PR:

?The team has built an incredible gaming platform that is used by over 150 million players worldwide. We intend to continue to support and grow PlayerScale?s technology, and we look forward to building great new experiences on Yahoo! using the PlayerScale platform.?

And here is PlayerScale CEO Jesper Jensen?s blog post on the deal:

?Today is a great day ? both in our journey with PlayerScale and for users of our Player.IO product. We are happy to announce the next big step toward our goal of building the best possible gaming infrastructure platform: we have been acquired by Yahoo!. And don?t worry, we?re not going anywhere. Our platform will continue to support the same great games that you love playing today ? and in fact, it will only get better from here!

Our goal has always been to help developers build the best possible games, without having to worry about building and scaling the infrastructure required to operate today?s biggest successes. In working with the folks at Yahoo!, it has become clear that we share this passion.

We have spent the past four years growing a three-person startup into a product that powers games played by over 150 million people worldwide and we are adding over 400,000 new users every day. In the last four months alone, we have increased our daily user growth rate by almost sixty percent. With Yahoo!?s backing, we can crank out awesome products and improvements to our platform faster than ever before. We will continue to support our existing product and deliver new services to help you grow and manage your success in cross-platform gaming ? whether it?s casual, social or mobile.

Today marks a milestone for PlayerScale and I want to sincerely thank the team, our developers and millions of users for the adventure so far and can promise there will be more to come.

- Jesper Jensen?


PlayerScale? develops software infrastructure for cross-platform gaming. Their backend software gives gaming publishers and aggregators the ability to scale titles across casual, social and mobile platforms in a rapid and seamless manner.

Hunting and hiking will likely coexist at Porter Creek - petoskeynews ...

BOYNE CITY -- Hunting should still be allowed at Porter Creek natural area west of Boyne City, but limited to deer hunting, be allowed only on specific dates and registration should be required, agreed members of the Charlevoix County Parks and Recreation Committee Monday night.

The county is working to enhance the 100-acre natural area by putting in walking trails, a parking lot and other improvements. This will likely encourage many more people to use the property for hiking, bird watching and family outings, explained parks and recreation director Ross Maxwell. The improvements are what prompted the board to make a decision as to whether hunting should still be allowed there as it is now.

The committee's decision will now go to the county board of commissioners for approval.

Deer hunting only, not hunting for any other type of animal, should be allowed between Oct. 1 and Dec. 31, the committee unanimously agreed. And hunters should be required to register with the county clerk's office so that there is record of how many hunters are on the property at any given point in time and to ensure it does not become oversaturated.

The idea to register hunters was suggested by county commissioner Chris Christensen, who attended the meeting in an unofficial capacity.

"I'm not opposed to the hunting thing, but with the limited size of the property and the distance that a bullet or round would travel, I would wonder if some consideration should be taken so that anyone hunting there should register ..." Christensen said. He also expressed that not allowing hunting in September is a good idea because so many people are still out walking then.

Little Traverse Conservancy requires hunters to register when using some of its preserves, said committee member Susan Vrondran, but "It's a lot of bookkeeping."

The committee will have to figure out who will enforce the rule and who will be in charge of registration, said Maxwell. It could overwhelm current county parks and recreation staff, he explained.

She would vote for no hunting to be allowed at the park at any time to ensure safety, said former county commissioner Shirlene Tripp. Those on vacation might not be aware of hunters, she said.

"We didn't want any hunting because of the safety, but we should compromise," said Vrondran.

Also on Monday, the committee heard an update on renovations coming to Whiting Park west of Boyne City.

Performance Engineers, a Charlevoix company, is working to develop a conceptual plan to re-configure the campground and expand the number of sites with electric hookup, reported Maxwell.

"It will make the sites more useful for modern-style camping," he said.

Other possibilities for the campground include levelling areas for flatter sites, building new bathrooms, adding a pavilion for the swim school, weddings and picnics, and adding a boat launch and fish shanty launch.

He hopes to have a design the committee can agree on and send along to the county board of commissioners for approval by the end of the summer.
