Check out this article on Marine Protected Areas: Ending the Oceans' 'Tragedy of the Commons'

From the Science Daily Post: Ending the Oceans' 'Tragedy of the Commons'. See the rest of this article at: http://www.sciencedaily.com/releases/2010/09/100914095930.htm

ScienceDaily (Sep. 15, 2010) — Leading international marine scientists are proposing radical changes in the governance of the world's oceans to rescue them from overfishing, pollution and other human impacts.

Based on a successful experiment in Chile, the researchers say a new approach to marine tenure could help to reverse the maritime 'tragedy of the commons' which has led to the depletion of fish stocks worldwide.

"Marine ecosystems are in decline around the world. New transformational changes in governance are urgently required to cope with overfishing, pollution, global changes, and other drivers of degradation," says Professor Terry Hughes of the ARC Centre of Excellence for Coral Reef Studies and James Cook University, one of the authors of a new scientific paper advocating sweeping reform of ocean governance.

"In recent years there has been a growing appreciation that the health of ecosystems like the oceans and human wellbeing are closely linked," says co-author Dr. Per Olsson of the Stockholm Resilience Centre. "Unfortunately, typical governance arrangements don't effectively link these two essential elements, when trying to manage fishing pressure for example. They are often too rigid and don't cope well with surprises or changed conditions."

A combination of fisheries collapses and the move to democracy in Chile, quite by chance, provided the opportunity to try out some new arrangements for looking after fisheries, involving a partnership of fishers, scientists and managers.

"There was a general recognition that Chile's fish stocks were in trouble," says Professor Carl Folke, also from the Stockholm Resilience Centre and the Beijer Institute. "Things were turbulent and people were looking for answers and that made them open to new approaches. There was also good scientific understanding of the coastal ecosystems of the region on which to base a new management plan."

Fishers and scientists had been working together on the problem for some years, sharing knowledge and building trust. This led to the trialling of new co-operative models for fishery management, based on the latest that science can reveal about the state of the fish stock and the surrounding marine ecosystem.

The result is a revolutionary national system of marine tenure that allocates user rights and responsibilities to collectives of fishers.

"Although fine tuning is always needed to continue to build resilience of this new regime, this transformation has improved the sustainability of the interconnected social-ecological system," Prof Folke adds.

A vital ingredient in the change was the move by Chile to democracy after a 17-year dictatorship. This opened the way for reform of the laws governing fishing rights.

The new laws gave exclusive ocean territories to local 'artisanal' fishers, and excluded the big industrial fishing fleets, which had their own exclusive fishing zone.

Scientists and small fishers then worked together to understand and rebuild the shattered fish stocks in their zone, leading to a shared vision and voluntary agreements on how to manage them. Fishing pressure was reduced in the industrial fishing zone by cutting the number of big vessels.

Professor Hughes says the Chilean experience contains lessons which can potentially apply anywhere in the world where a fishery is in trouble and there is good scientific data on the marine environment.

"You need a shared recognition that something has to be done, you need a good understanding of the marine ecosystem and how to regenerate it, you need a strong rapport between scientists and fishers, and you need a political moment when sweeping changes can be brought in," he says.

"If you have all those things, there is a good chance you can avoid the marine 'tragedy of the commons' which has been a feature of fisheries around the world in the past half century."

The research indicates the key to managing fisheries may depend on creating agreements that are both voluntary and flexible enough to cope with changes in the ocean environment, leading to fisheries that are both ecologically and socially sustainable.

interesting article, thanks steve

From a viewpoint of someone who has tried integrated coastal management approaches in Central and Southern Philippines, I would agree that obtaining marine data is important in determining for instance, what fisheries management tool to use. Imposing a fishing ban during specific time of the year when fish species are gravid (or "pregnant" or carries eggs) is an offshoot of having sufficient marine data on the biology of target species. To go to a more advance stage of managing critical fishery sites is to zero in on the social dimension: how fish is used, who decides what price to assign, who decides where fish suppy would be made available at what price, and how fish supply could meet current demand (to consider lifestyle of dominant groups). This is where social marekting comes in: using unconventional ways of selling ideas such as changing lifestyle in order to achieve a conventional goal: fish food sufficiency. There are roles to play for key stakeholders and minor roles for those in the periphery. Decision making is crucial and difficult to make since huge interests are involved. So staging discussions and in the process, determining opposing perspectives could unlock conflict resoultions. Talks have to begin. With Rare, these discussions have started the first time they set out to do Sustainable Fisheries in the Philippines. Leading the pack? Pioneering? Call it by any other name..It still stands out to be simply, Rare Conservation. :)

Beautifully said, Ruby!
