Three-quarters of the world’s reefs at risk

Representatives from ZSL’s Conservation and Living Collections teams on Thursday participated in the launch of the Reefs at Risk Revisited report launch.

Dr Heather Koldewey, ZSL’s International Marine and Freshwater Conservation Programme Manager, said ‘This report provides an invaluable compilation of the latest and most comprehensive data set on the world’s coral reefs.
These data support ZSL’s position that we are in imminent danger of losing most of our coral reefs over the next 30-50 years unless there is a rapid and global action. ZSL is committed to such action through diverse programmes that span from grass roots initiatives like EDGE Coral Reefs, to our international policy work supporting GLOBE’.

In the 10 years since the first Reefs at Risk analysis, threats have increased by 30 percent. This includes recent impacts from climate change which causes rising ocean temperatures and coral bleaching.

The most immediate and direct threats arise from local sources, which currently threaten more than 60 percent of reefs (about 150,000 sq km of reefs). Local threats include overfishing, destructive fishing, coastal development and pollution.

Unless steps are taken to reduce local pressure and reduce the emission of greenhouse gases, the percent of threatened reefs will increase to more than 90% by 2030 and to nearly all reefs by 2050.

Most vulnerable

The report identifies 27 nations most vulnerable to coral reef degradation and loss in the world (of 108 reef countries assessed). The nine coun¬tries most vulnerable to the effects of coral reef degradation, due to high dependence on coral reefs and low adaptive capacity, are: Haiti, Grenada, Philippines, Comoros, Vanuatu, Tanzania, Kiribati, Fiji, and Indonesia.

The report makes 60 recommendations for action. ZSL’s coral reef conservation efforts respond to many of these, including supporting and implementing effective marine protected areas (in Chagos and the Philippines through Project Seahorse), building conservation and management capacity in coral reef nations (EDGE Corals, Project Seahorse), supporting the most vulnerable countries (e.g. Philippines through Project Seahorse) and influencing policy (Climate Change programme; GLOBE Action Plan for Coral Reefs).

The report was led by the World Resources Institute, along with the Nature Conservancy, the WorldFish Center, ICRAN, UNEP-WCMC, and GCRMN. One of the report’s authors, Dr Allison Perry, is a former member of the Project Seahorse team.

It’s time humans stopped to consider Earth’s health

From Michael McCarthy in The Independent today

I wasn’t suggesting for a second that anyone should go hungry; but I was suggesting there will be serious consequences for the planet of this intensification, and of many other aspects of the exploding scale of the human enterprise, as it threatens to overwhelm the Earth’s natural systems in the decades to come.

Are there any limits on what humans can do? Asked rhetorically, the question invites the smiling, triumphant answer, No!, complete with happy-clappy exclamation mark. But to ask it the other way – that is, to ask it simply, in all seriousness – seems to me something that doesn’t happen any more. In fact, the absence of this question seems to be a great gap at the heart of our current creed, which we might term liberal secular humanism, as we approach one of the climaxes of human history, which is the coming clash between humans as a species, and the Earth which is our only home.

I wrote about this three weeks ago, asking how much room there will be in the 21st century world for non-human creatures, using as an example the future fate of insects, which may well have to be sacrificed wholesale, if intensive farming has to be doubly intensified to feed nine billion people by 2050. I wasn’t suggesting for a second that anyone should go hungry; but I was suggesting there will be serious consequences for the planet of this intensification, and of many other aspects of the exploding scale of the human enterprise, as it threatens to overwhelm the Earth’s natural systems in the decades to come. There was an animated reader response to this, so I should like to return to it.

Climate change is only the most dramatic (and controversial) of these consequences. There are many others visible already, about which there is no dispute, ranging from the worldwide collapse of fish stocks to the disappearance of wildlife abundance from the British countryside. Liberal secular humanism certainly acknowledges these disturbing trends; it is greatly concerned about them, shakes its head sadly and strives to prevent them; but what it does not do, is put the whole picture together.

It does not allow the conclusion to which the rapidly increasing degradations of the natural world are all pointing: that a fundamental conflict is looming between the Earth and Man (I use the term in the biological sense of the species Homo sapiens).

This failure to recognise the fundamental nature of the clash will, at the very least, greatly handicap our response to it. I think it arises from our current creed’s greatest failing, its deficit of spirituality, by which I mean a failure to see existence as anything other than human-centred. Liberal secular humanism, which you could argue has been our belief system since the Second World War, has a single, honourable aim: to improve human welfare. It wants people everywhere to be happy, and free from want and fear and disease, and to live fulfilled lives.

What it doesn’t do is allow that there might just be a problem, an intrinsic problem, with people as a species. That is absolute anathema.

You can understand why: poverty is terrible enough without suggesting that people as a whole are in some way flawed. Yet for the Greeks, the founders of our culture, this idea was central to their morality.

There was a continual problem with Man. Man was glorious, almost God-like, and continually striving upwards; yet only the Gods were actually Up There, and if Man tried to get too high, as he often did, the Gods would destroy him. The Gods represented Man’s limits.

The principal fault of Oedipus in Sophocles’ Oedipus Rex, remember, was not that he murdered his father and married his mother; those were incidentals of his fate. His real fault was that he thought he knew everything, he had answered the riddle of the Sphinx, he was Mr Clever. The Gods showed him that he wasn’t (and in the greatest of all tragic ironies, he puts out his eyes to punish himself for having been blind to his true situation, which now he can see).

In the modern consensus, in liberal secular humanism, this spiritual view of Man of having limits, of not being able to do everything he chooses, and of potentially being a problem creature, is missing entirely. There is no trace of it whatsoever. Still less, of course, is there any trace of the more recent, Christian version of it, which is Original Sin. Just the opposite: in our current creed, Man is not Fallen, Man is Good; so, as they used to say of General Motors and America, what’s Good for Man is necessarily Good for the Planet.

Except that it isn’t. What’s Good for Man may wreck the planet, and with the mushrooming expansion of humans numbers, increasingly seems likely to. Yet so forceful is our creed that it stamps on the very formation of the thought that Man may be the Earth’s problem child. Suggest it and you will be met with a sigh, and a knowing chuckle; or even more likely, indignant confrontation. So the fundamental conflict which is coming between Us and the Earth, this major moment of history, which evidence everywhere increasingly points to, is not recognised in our dominant belief system; and thus is not addressed.

We humans have always thought ourselves different in kind from other creatures, principally for our use of language and our possession of consciousness. There is another reason, which is becoming clearer; we are the only species capable of destroying our own home (which you might think of as Original Sin in its ecological version).

It seems to me that moral account needs to be taken of this, in the heart of what we believe and understand about ourselves; all the indignant denial of it – as the noble struggle continues to raise so many people from misery to decent life – will not prevent it from being so.

Forest and Bird welcomes new Sub-Antarctic protection

 

Good news for Forest & Bird and conservation , but a selcctive win…. Yes indeed – NZ Govt is being very ‘particular’ in their conservation efforts – they are choosing to be particular and conserving just that site!  

Forest & Bird today welcomed the government’s decision to expand marine reserves and marine protected areas around New Zealand’s Sub-Antarctic islands.

Conservation Minister Kate Wilkinson announced that a marine reserve would be created covering the entire 12-nautical mile territorial seas around Antipodes Island.

Of the territorial waters around the Bounty Islands, 58 percent will be made a marine reserve and Danish seine fishing will be banned on the western side and south east corner of the remaining territorial waters.

A marine reserve will cover 39 percent of the territorial waters around Campbell Island and a potential giant crab fishery will be allowed in the remaining area with a review after five years.

Forest & Bird Advocacy Manager Kevin Hackwell said Forest & Bird welcomed the expansion of protection in the Sub-Antarctic islands. The only existing marine reserve in New Zealand’s sub-Antarctic region is in the territorial waters around the Auckland Islands.

“Including all of Antipodes Island as a marine reserve is a good result for conservation.” Hackwell said.

“Forest & Bird would rather have seen all of the territorial seas of the other two Bounties and Campbell Islands fully protected.

“But the outcome of 60 percent of the Bounties being put in a marine reserve, with trawling restriction in the remaining area, is a big improvement on the present lack of protection.

“The decision not to fully protect the territorial seas around Campbell Island on the basis of a possible crab fishery that does not yet exist is disappointing.

“All the territorial seas around New Zealand’s Sub-Antarctic islands have World Heritage status and as a country we should be recognising their international status with appropriate protection.

“This has been the result of an intensive year-long process in 2008, involving all the stakeholders.

“We should look at setting up similar forums for setting up marine reserves in other parts of New Zealand,” he said.

COMMENT Barry Weeber Pity the Government only accepted the fishing industry proposals for Campbell and Bounty Islands. World Heritage Area and species still at risk.

MY COMMENT Yes indeed – NZ Govt is being very ‘particular’ in their conservation efforts – they are choosing to be particular and conserving just that site!

Are Africa’s seas getting protection they deserve, finally?

South Africa maps first deep-sea preserve

The Independent/AFP

Underwater canyons, deep-sea coral reefs and sponge banks are part of a unique ecosystem that South Africa wants to save within its first deep-sea marine protected area. After 10 years of consultations, South Africa has mapped the boundaries for the proposed reserve stretching 100 kilometres (60 miles) from the eastern KwaZulu-Natal coast.The mapping required synthesising the many divergent interests in the Indian Ocean waters, with 40 industries from fishing to gas lines to jet skis operating in an area home to about 200 animal species and their ecosystems.”All of this data was then entered into conservation planning software in order to identify areas of high biodiversity while avoiding areas of high (economic) pressure,” said Tamsyn Livingstone, the researcher who heads the project.The conservation area is being born in a spirit of compromise, which will allow people and companies to continue using the protected waters in zones designated as lower-risk threats to biodiversity.The scheme still needs to be passed into law, but would join South Africa’s existing network of marine preserves strung along its 3,000-kilometre (1,800-mile) coast stretching from the warm Indian Ocean to the cold southern Atlantic.South Africa has embraced this “participatory” method to protecting species living in its water, an approach pioneered in California and Australia.Global goals for protecting biodiversity have been debated for two weeks at a UN summit in Nagoya, Japan (http://www.cbd.int/cop10/), in an effort to set goals on saving habitats which would help to end the mass extinction of species.Environmental groups want 20 percent of coastal and marine areas protected, they say China and India are lobbying for six percent or lower. Talks are supposed to wrap up on Friday.Part of the challenge is in protecting species that are more often than not still unknown. Only one quarter of the estimated million species in the oceans have been discovered.A global census of the oceans unveiled in early October uncovered prehistoric fish thought dead millions of years ago, capturing researchers’ imaginations about what else lurks in the deepest parts of the sea.”Offshore biodiversity is not well known,” said Kerry Sink of the South African National Biodiversity Institute.Exploring the seas remains an expensive project, prompting South African researchers to reach agreements to share information with fisheries, coastal diamond mines and the oil industry.”South Africa’s plan is unique in covering all industry sectors to ensure that biodiversity planning minimizes the impact on industry,” she said.”Healthy offshore ecosystems underpin healthy fisheries and keep options open for future generations.”With growing worries about climate change, scientists say the deep seas could become an important source of protein for the planet, because water temperature changes less at great depths.That assumes that the growth of industry can be managed alongside the marine life, especially as oil companies find ways to drill in ever-deeper waters.The explosion of a BP oil rig in April off the Louisiana coast, rupturing a 1,500-metre deep well, highlighted the risks.It took five months to shut off the leak which caused the biggest the oil spill in US history, with 205 million gallons of oil flowing into the Gulf.

In this Year of Biodiversity, are we to celebrate or commiserate?

In this year of Biodiversity, we need a debate about the state of the UK enviromment. Here’s is a start by Michael Mccarthy of The Independent   

The tragic loss of British wildlife

Some truths are never voiced because they are virtually impossible to perceive. For example, I have never heard anyone declare how appallingly impoverished Britain’s wildlife is. That’s not the subject of a national debate (although it ought to be). That’s not even a national perception. In fact, I don’t know if it’s anybody’s perception. But it’s no less than the truth.

 I have spent most of my life hearing time and again a peculiarly smug proposition, which is that “Britain’s xxxx is the best in the world.” Fill in the exes at your leisure from a long list: civil service, dinner-party conversation, breadth of heritage, movie technology, sense of humour, overseas broadcasting, gentlemen’s tailoring, armed forces, you name it. It’s a statement which trips ever so comfortably off the tongue. But how would you like to be told: “Britain’s wildlife is among the poorest in the world”? How would that look on a tourist poster?

Not that what we have isn’t wonderful in itself, not that we don’t cherish every feather, every flower, every footprint of it. But the fact remains that our wildlife today, British biodiversity, is but a mean, miserly fraction of what its true, “natural” level is, of what it has been in the past and what it really ought to be. And we are blind to the fact.

The reason is a curious one: every generation tends to take what it finds around it to be the norm. American marine biologists have coined an evocative term for this: the shifting-baseline syndrome, first applied to the management of fish stocks. You may think that the baseline, or natural state, of a stock is what it was at the start of your career, yet actually it may once have been very much greater. And of course this applies right across the natural world – to poppies, to skylarks, to tortoiseshell butterflies, of which your grandparents saw thousands, your parents saw hundreds, you saw dozens, and your children will see the odd one and never apprehend there is anything amiss. They will gaze on impoverishment and take it as standard.

I have felt this for a long time, yet my sense of it was triggered anew this week when I found myself in the delta of the River Mississippi, covering the BP oil spill. The Louisiana marshes are swirling with sparky life, graced with clouds of exotic herons and egrets and birds of prey, even at the side of the road, and I was put in mind of the Norfolk Broads or the Fens, wildlife showpieces of our own, and thought how little they had in comparison.

Louisiana is sub-tropical, of course, and species richness increases as you move towards the equator, so let’s do a comparison in more temperate zones. How many wild bird species do you think have been recorded in St James’s Park in central London? About 65. How many in Central Park in New York? More than 200. Or we can bring it back to Europe. We have about 60 butterfly species in Britain; go to France and you will find 250. We have but three woodpecker species and one, the lesser spotted, you will be lucky to see in a lifetime now; go to France and you can find seven. And it’s the same story with mammals and reptiles and amphibians and pretty much everything.

This is partly geographical accident; since we are cut off at the end of Europe it is impossible for many species to replenish their populations from the continent. But why do we often seem to have so little of what we do have? Why is there so little abundance?

Three years ago, in a groundbreaking book, Silent Fields, the biologist Roger Lovegrove provided the answer: he revealed in detail how, for the best part of 400 years, an unremitting campaign of organised slaughter was waged against wildlife in Britain. From the time of Henry VIII until the First World War, systematic killing on a scale unthinkable today was directed at most of our familiar wild animals and many wild birds: badgers, foxes, hedgehogs, otters; green woodpeckers, jays, kingfishers, bullfinches. Millions were slaughtered, first, by country people, from about 1530 to 1800, to claim bounties under the Tudor vermin laws, and second, by gamekeepers controlling predators on aristocratic shooting estates, from about 1800 to 1914.

Besides “thinning out” wildlife everywhere, this drove to the edge of the abyss, and to the remote corners of the land, a whole series of creatures which in Shakespeare’s day were familiar to everyone in the countryside: polecat, pine marten, wild cat, hen harrier, red kite. We have never recovered; and since the arrival of intensive farming 40 years ago the situation has only worsened: half the birds in the fields of England have disappeared since the Beatles broke up. Britain’s wildlife is one of our dearest assets and a balm for our souls, but it is very far from what it ought to be, and its impoverished nature seems to me now to be its most striking attribute.

Got those Mississippi geography blues

As a one-time aficionado of folk-blues, I had heard and listened to many of the famous singers who came from the Mississippi Delta – Muddy Waters, John Lee Hooker, Howlin’ Wolf, Robert Johnson – so when I got to the mouth of the great river this week I was hot to find their traces. It took me some time to realise that the delta of the Mississippi river, and the Mississippi Delta, are two quite separate locations, the latter (where the bluesmen came from) being a plain in the north-west of the state. Just thought I’d pass it on.
