The Ocean Tipping Points project is a collaboration of natural and social scientists, lawyers, environmental managers, and stakeholders working to understand what drives abrupt ecological shifts, and how they might be prevented or reversed. In this initial blog, we introduce the concept of tipping points and highlight our latest research. In upcoming blogs, some of our researchers will present their work in more detail and discuss the implications for our case study regions and for the science and management community more widely.

Reaching a tipping point

Sea otters were once a common sight in kelp forests along vast expanses of the west coast of North America, until fur traders decimated nearly every otter population in the 1800s.  Without otters, the kelp forests began to disappear. Sea urchin populations exploded in the absence of their main predators—otters—and started grazing down the kelp forests, creating a patchwork of ‘urchin barrens’ where kelp forests were once prolific. Without the complex habitat provided by kelp, numerous marine species, including commercially important fish, can lose their main source of food and shelter.

The OpenChannels Team live blogged throughout the 2014 World Parks Congress. John Davis was on-scene in Syndey, updating us on the conference's Marine Theme. We also curated the most useful and interesting tweets coming out of the conference in order to save them from disappearing into the ether. You can see everything as it happened in the live blog's archive at http://openchannels.org/chat/wpc-2014.

This not-so-live blog contains relevant highlights for the ocean and coastal community. If you think we missed anything important, please let us know in the comments below. Thank you!

The VALMER project (www.valmer.eu) convened a workshop at the International Marine Conservation Congress (Glasgow, August 2014) to share experiences about the application of ecosystem service assessments in marine conservation. We specifically asked participants about barriers to the use of ecosystem services assessment for marine conservation. In addition to the ‘usual’ answers about “poor data availability, incomplete knowledge to link ecosystem functions and ecosystem services, and difficulties in the application of monetary valuation methods,” participants repeatedly cited “the manner” in which ecosystem services assessments are conducted as a potentially significant barrier to their eventual use, or lack thereof. The engagement process, we were told, influences how the ESA results of the assessment are perceived and subsequently used. Furthermore, there was a strong sense from participants that how stakeholders, decision-makers and any other interested parties are involved in an ecosystem services assessment has a direct effect on how the results of the assessment will be treated and used. But why?

In preparation for the forthcoming World Parks Congress, the November 6th edition of Nature includes a series of comments in which "experts share their priorities for what must be done to make protected areas more effective at conserving global biodiversity". These include several contributions which are particularly relevant to marine protected areas.

Peter Jones discusses the need to Assess Governance Structures:

The recent much lauded announcement that the "US designates 1.2-million-km2 MPA in which all commercial extraction is banned" begs the question - How can three MPA expansions 800-1000 km apart which exclude the main fishing grounds for stocks that are known to be severely depleted be so widely and uncritically applauded? This is not a single MPA therefore the press release claim that it represents the largest MPA designation in the world is a false one that is being wrongly reinforced through uncritical repetition. These designations represents a political-economic compromise which arguably breaches the Magnuson-Stevens Fishery Conservation and Management Act, at least in spirit, in that it is designed to leave the grounds for a severely over-exploited fishery open to exploitation. Then there is, of course, the question of how this remote area will be enforced.

The new president of the European Union recently appointed a whole new team of commissioners, including the appointment of the Maltese politician, Karmenu Vella, as the new EU Commissioner for the Environment and Maritime and Fisheries posts (see Joan Edward's blog on this), but is the environment already sinking down his agenda?

Further to the recent blog about how coal scuttles coral hopes, see this ABC News Program about the Great Barrier Reef Marine Park (GBRMP) and Abbot Point dredging impacts. The program features MPAG case study contributor Jon Day criticizing the Australian government's misrepresentation of the scientific advice of the GBRMP Authority, from which he recently resigned.

On August 12th, Barbuda Council signed into law a sweeping set of new ocean management regulations that zone their coastal waters, strengthen fisheries management, and establish a network of marine sanctuaries. This comes after seventeen months of extensive community consultation and scientific research supported by the Waitt Institute. With these new policies, the small island of Barbuda has become a Caribbean ocean conservation leader and global role model. The regulations establish five marine sanctuaries, collectively protecting 33% (139 km2) of the coastal area, to enable fish populations to rebuild and habitats to recover. To restore the coral reefs, catching parrotfish and sea urchins has been completely prohibited, as those herbivores are critical to keeping algae levels on reefs low so coral can thrive. Barbuda is the first Caribbean island to put either of these bold and important measures in place.  “This will definitely benefit the people of Barbuda, and Antigua as well. No part of this is meant to hurt fishers. It’s the reverse – ensuring that they have a livelihood that will last in perpetuity,” said Arthur Nibbs, Chairman of the Barbuda Council and Antigua and Barbuda Minister of Fisheries.

Maybe it’s all those summer reading lists that draw me in every summer to distant places and terrific characters. But it seems like a good time to appreciate some of the many great novels that are set in and around our nation’s marine protected areas. Social scientists are now documenting what writers have known for centuries – telling a compelling story is the best way to help people understand and engage in an issue. 

Not that these stories preach about marine conservation. Fortunately, these authors know that’s not the way to get our attention. Rather, they show us how individuals interact with specific places – and how these places work their way into our memories and hearts.

Here are a few suggestions for summer reading --- we’d love to hear your ideas and comments too.
