Politics podcast: Anna Krien on the climate wars

The Conversation - Mon, 2017-07-03 14:51

Melbourne-born author Anna Krien’s latest Quarterly Essay explores the debates on climate change policy in Australia and the ecological effects of not acting.

She interviewed farmers, scientists, Indigenous groups, and activists from Bowen to Port Augusta. She says climate change denialism has transformed into “climate change nihilism”.

Krien says the Finkel review provides another opportunity in a long line of proposals to take up the challenge of legislating clean energy. “We just need to get that foot in the door. The door has been flapping in the wind for the past decade.”

On a current frontline battle – the planned Adani Carmichael coalmine – she found the people who would be affected were being ignored and blindsided.

Meanwhile, the potential for exploitation of local Indigenous peoples through “opaque” native title legislation was high. “Outsiders are not meant to understand it and to tell you the truth you get the sense that insiders aren’t meant to understand it either.”

Signal crayfish – invader, cannibal, survivor

The Guardian - Mon, 2017-07-03 14:30

Appletreewick, Yorkshire Dales Its body is as dark as the river at its deepest, where the peat-stained water turns as black as molasses

The heatwave hits its stride before breakfast, building to a dog day intensity that will relent only with the last red moments of the sunset. For the long hours between, an endless afternoon, the light ceases to move, training its intensity on the elderflower, oxeye daisies and buttercups of Wharfedale until their colours take on the bleach-brightness that signals high summer in England.

The weather brings people out of hibernation, and into encounters with unfamiliar forms of life. “Look at the size of that crayfish!” The woman paddling in the untypically warm river Wharfe near Appletreewick points near her feet, causing half a dozen swimmers to coalesce around the spectacle.

Earth's wildernesses are disappearing, and not enough of them are World Heritage-listed

The Conversation - Mon, 2017-07-03 13:44

Earth’s last intact wilderness areas are being rapidly destroyed. More than 5 million square km of wilderness (around 10% of the total area) have been lost in the past two decades. If this continues, the consequences for both people and nature will be catastrophic.

Predominantly free of human activity, especially industrial-scale activities, large wilderness areas host a huge range of environmental values, including endangered species and ecosystems, and critical functions such as storing carbon and providing fresh water. Many indigenous people and local communities, who are often politically and economically marginalised, depend on wilderness areas and have deep cultural connections to them.

Yet despite being important and highly threatened, wilderness areas have been almost completely ignored in international environmental policy. Immediate proactive action is required to save them. The question is where such action could come from.

In a paper published in Conservation Biology, we argue that the United Nations’ World Heritage Convention should expand the amount of wilderness included in its list of Natural World Heritage Sites (NWHS).

Wilderness areas are underrepresented among the 203 sites currently on the list. The World Heritage Committee’s meeting in Poland this week offers a good opportunity to redress the balance.

Whither wilderness?

The World Heritage Convention was adopted in 1972 by UNESCO (the United Nations Educational, Scientific and Cultural Organization) to conserve the world’s most valuable natural and cultural sites – places of exceptional importance to all of humanity and future generations. Each one is unique and irreplaceable. Currently, 193 countries (almost the entire world) are parties to the convention, which has inscribed 203 natural sites around the world.

World Heritage Status is granted to places with “Outstanding Universal Value”, which is defined based on three pillars. First, a site must meet one of the four criteria for listing as natural World Heritage (aesthetic value, geological value, biological processes, and biodiversity conservation). Second, a site must have “integrity” and “intactness” of its values (in other words, it must be in excellent condition). Finally, a site must be officially protected by the national or subnational government under whose jurisdiction it falls.

Wilderness areas can be associated with all four of the natural criteria, as well as the integrity and intactness requirements. What’s more, a wilderness by definition cannot be recreated once it is lost. The argument for protecting wilderness areas by adding them to the NWHS list is therefore compelling.

We created the most up-to-date maps of terrestrial wilderness using recent maps of human pressure and assessed the World Heritage Convention’s current coverage of wilderness areas. We found that some 777,000 square km (around 2% of the total) are already protected in 52 Natural World Heritage Sites.

Very little of the world’s wilderness (green) is within natural World Heritage Sites (pink). Author provided

For example, more than 90% of the World Heritage-listed Purnululu National Park in the Kimberley region of Western Australia can be defined as a wilderness area. Similarly, the Okavango Delta in Botswana features more than 18,000 square km of wilderness, containing many of the world’s most endangered large mammals.

Wilderness boosts heritage value

In these cases, wilderness areas are likely contributing to the Oustanding Universal Value of of these World Heritage Areas – which as explained above is a key consideration in how they are managed and protected.

One way to strengthen this protection further would be to redraw the boundaries of natural World Heritage Areas to include more wilderness. This would help to preserve the conditions that allow ecosystems and other heritage values to thrive.

Our study identified broad gaps in wilderness coverage by the World Heritage Convention. Some places are already protected by national governments and could therefore be added to UNESCO’s list, such as the Hukaung Valley Tiger Reserve in Myanmar, which contains 4,000 square km of wilderness, and the Eduardo Avaroa Andean Fauna Reserve in Bolivia, which has 9,000 square km.

The places we have identified, and others, could potentially be designated as new Natural World Heritage Sites if they meet the other strict criteria for Outstanding Universal Values and integrity.

The World Heritage Convention could better achieve its objectives and make a substantial contribution to the conservation of wilderness areas by doing these four things:

  1. formally acknowledge the Outstanding Universal Values of wilderness areas

  2. strengthen the current protection of wilderness within NWHS

  3. expand or reconfigure current NWHS to include more wilderness, and

  4. designate new NWHS in wilderness areas.

It’s up to national governments to submit sites for inscription as NWHS, and we urge them to consider wilderness when doing so. This will strengthen their applications, and provide wilderness areas with the extra protection they need.

The UNESCO World Heritage Committee’s meeting in Poland this week will consider two sites with significant wilderness areas for World Heritage status: Qinghai Hoh Xil Nature Reserve in China and Los Alerces National Park in Argentina. We urge the committee to approve these sites, and use this to spur further opportunities to raise the profile of wilderness conservation worldwide. It is an obvious win-win.

The clock is ticking fast for our last wilderness areas and the biodiversity they protect. Immediate action is needed.

How an obscure Austrian philosopher saw through our empty rhetoric about 'sustainability'

The Conversation - Mon, 2017-07-03 13:06

“Sustainability” is, ironically, a growth industry. Ever since the term “sustainable development” burst onto the scene in 1987 with the release of Our Common Future (also known as the Brundtland report), there has been a dizzying increase in rhetoric about humanity’s relationship with our planet’s resources. Glossy reports - often featuring blonde children in front of solar panels or wind turbines - abound, and are slapped down on desks as proof of responsibility and stewardship.

Every few years a new term is thrown into the mix - usually preceded by adjectives like “participatory” or “community-led”. The fashionability of “resilience” as a mot du jour seems to have peaked, while more recently the “circular economy” has become the trendy term to put on grant applications, conference notices and journal special editions. Over time journals are established, careers are built, and library shelves groan.

Meanwhile, the planetary “overshoot”, to borrow the title of a terrifying 1980 book, goes on - exemplified by rising concentrations of atmospheric carbon dioxide, warmer oceans, Arctic melting, and other signs of the times.

With all this ink being spilled (or, more sustainably, electrons being pressed into service), is there anything new to say about sustainability? My colleagues and I think so.

Three of us (lead author Ulrike Ehgartner, second author Patrick Gould and myself, recently published an article called “On the obsolescence of human beings in sustainable development”.

In it we explore the big questions of sustainability, drawing on some of the work of an unjustly obscure Austrian political philosopher called Gunther Anders.

Who was Günther Anders?

He was born Günther Siegmund Stern in 1902. While he was working as a journalist in Berlin, an editor wanted to reduce the number of Jewish-sounding bylines. Stern plumped for “Anders” (meaning “other” or “different”) and used that nom de plume for the rest of his life.

Anders knew lots of the big philosophical names of the day. He studied under Edmund Husserl and Martin Heidegger. He was briefly married to Hannah Arendt, and Walter Benjamin was a cousin.

But despite his stellar list of friends and family, Anders himself was not well known. Harold Marcuse points out that the name “Stern” was pretty apt, writing:

His unsparingly critical pessimism may explain why his pathbreaking works have seldom sparked sustained public discussion.

While Hiroshima and the nuclear threat were the most obvious influences on Anders’ writing, he was also crucially influenced by the events at Auschwitz, the Vietnam War, and his periods in exile in France and the United States. But why should we care, and how can his ideas be applied to modern-day ideas about sustainability?

Space precludes a blow-by-blow account of what my colleagues and I wrote, but two ideas are worth exploring: the “Promethean gap” and “apocalyptic blindness”.

Anders suggested that the societal changes wrought by the industrial age – chief among them the division of labour – opened a gap between individuals’ capability to produce machines, and their capability to imagine and deal with the consequences.

So, riffing on the Greek myth of Prometheus (the chap who stole fire from Mount Olympus and gave it to humans), Anders proposed the existence of a “Promethean gap” which manifests in academic and scientific thinking and leads to the extensive trivialisation of societal issues.

The second idea is that of “apocalyptic blindness” – which is, according to Anders, the mindset of humans in the Age of the Third Industrial Revolution. This, as we write in our paper:

…determines a notion of time and future that renders human beings incapable of facing the possibility of a bad end to their history. The belief in progress, persistently ingrained since the Industrial Revolution, causes the incapability of humans to understand that their existence is threatened, and that this could lead to the end of their history.

Put simply, we don’t want to look an apocalypse in the eye, even if it’s heading straight towards us.

The climate connection

“So what?” you might ask. Why listen to yet another obscure philosopher railing about technology, in the vein of Lewis Mumford and Jacques Ellul? But I think a passing knowledge of Anders and his work reminds us of several important things.

This is nothing new. Recently, the very notion of ‘progress’ has come under renewed assault, with books questioning our assumptions about it. This is not new of course - in a 1967 short story collection about life at the United Nations, Shirley Hazzard had written:

About this development process there appeared to be no half-measures: once a country had admitted its backwardness, it could hope for no quarter in the matter of improvement. It could not accept a box of pills without accepting, in principle, an atomic reactor. Progress was a draught that must be drained to the last bitter drop.

The time - if ever there was one - for tinkering around the edges is over. We need to take stronger action than simply pursuing our feelgood preoccupation with sustainability.

This begs the question of who is supposed to shift us from the current course (or rather, multiple collision courses. That’s a difficult one to answer.

The hope that techno-fixes (including 100% renewable energy) will sort out our problems is a dangerous delusion (please note, I’m not against 100% renewables - I’m just saying that green energy is “necessary but not sufficient” for repairing the planet.

Similarly, the “circular economy” has a rather circular feeling to it – in the sense that we’ve seen all this before. It seems (to me anyway) to be the last gasp of the “ecological modernist” belief that with a bit more efficiency, everything can simply keep on progressing.

Our problems go far deeper. We are going to need a rapid and fundamental shift in our values, habits, behaviours, and outlooks. Put in Anders’ terms, we need to stop being blind to the possibility of apocalypse. But then again, people have been saying that for a century or more.

Kingfisher gives a picture of many hues: Country diary 100 years ago

The Guardian - Mon, 2017-07-03 07:30

Originally published in the Manchester Guardian on 7 July 1917

SURREY
Helped by moisture from the north downs, the river to-day runs higher, swirling along by the tall grasses and the loosestrife, bending reeds, and flags, flowing above the few yellow blooms on the near banks, and lifting “water-blobs” like small boats, which rock a little while the tide runs in. Kingfishers on the wing show now of a deep, now of a pale blue as a momentary light strikes from the sun. They perch on a swaying willow stem which dips to the stream, then a glint flashes all along the stretch of water and one of them flies in and with it gives a picture of many hues. Swallows, skimming low, are wonderfully white in plumage when they make a sudden turn, and there is a constant low warbling of the smaller willow wrens. Up the bank, where the teasel is breast high and its prickly bloom is forming, linnets whistle a few notes before they move restlessly from bush to bush.

Here's what you need to know about exotic pets in Australia

The Conversation - Mon, 2017-07-03 06:08
Red-eared sliders were once popular pets but are currently banned in Australia. These turtles are still regularly found in the wild and being kept as illegal pets. Pablo Garcia-Diaz, Author provided

A taste for owning exotic animals can be addictive – the more flamboyant the better. Earlier this month border security agents found 50 live turtles and lizards smuggled in Lego boxes sent from Indonesia. In April customs officials found a parcel marked “2 pair shoes” that turned out to contain venomous vipers, tarantulas and scorpions.

According to the Animals Medicines Australia 2016 survey some two-thirds of Australian households have pets – more than 24 million animals in total. Not surprisingly, dogs and cats are the most popular (38% and 29% of households, respectively), whereas aquarium fish and birds rank somewhere in the middle (both 12%), and reptiles and less common mammals are kept in some households (both less than 5%).

The federal government largely legislates the owning of exotic pets. The law defines “exotic” as “animals that do not occur naturally in the wild in Australia” – which actually includes dogs and cats. However “domesticated mammals”, which also covers cows, sheep and other farm animals, are generally legal to buy and own. Commercial trade in exotic reptiles and amphibians, on the other hand, has been banned since 1999.

Whether an exotic animal is kept legally or not, some will find their way to the Australian wild through escape or release, posing a potential pest risk. There are some simple things governments and pet owners can do to improve the way this risk is handled, to keep animals and humans safe.

We don’t really know how many exotics are in Australia

Most local councils only require dogs (and sometimes cats) to be registered by their owners. Other pets, whether exotic or native, do not need to be registered. Indeed an owner of an exotic animal is not required to report or register the animal in any way. This means there are very little reliable data and it’s difficult to say how many exotic pets are kept in Australia.

We highlight two cases from our own research: birds and reptiles.

Bird-keeping is common in Australia, particularly of parrots and finches. More than half the bird species traded are exotic and mostly originate in South America, Africa and Asia. Rose-ringed Parakeets are one of the most commonly kept exotic pet bird, and the most frequently reported as having escaped. They are seen as a potential threat because they are a serious agricultural pest in its’ native and exotic distribution, and have a very high risk of establishing in Australia.

Reptiles – generally skinks, turtles and dragons – are less popular pets than birds. Nonetheless, judging from the posts on public trading webpages, a variety of native reptile species are kept and traded by hobbyists, also including crocodiles and snakes.

Unfortunately, little is known about native reptile trading in Australia and further research is needed. And while native reptiles can be kept legally, illegal exotic reptiles are a serious problem. In a previous article for The Conversation, we reported that 28 alien reptile species were illegally kept in Victoria between 1999 and 2012. More than a third were highly venomous snakes, posing a real risk to human safety.

Responsibly caring for exotic pets

If you own or want to buy an exotic pet, you must be aware of the regulations that apply to you (you can Google “exotic pet regulations” plus the name of your state or territory). Each jurisdiction keeps official lists of those species that may be kept within their borders, with or without a permit. These lists can be found on local government websites or obtained from their relevant departments.

People should also be able to register all of their pets, including exotic ones. Governments need to promote public awareness of the importance of registration (even if it’s not legally required), and ensure the processes are simple, accessible and affordable.

If you lose your exotic pet, it’s important to alert your state or territory biosecurity agency. Each jurisdiction has its own agency, but examples are the Western Australia Department of Agriculture and Food or Agriculture Victoria. If you want to recover your lost pet the best available option is to report your loss to one of the many missing animal websites.

Governments, when facilitating the registration process, will need to establish best practices to collect and analyse information so that the nature and extent of pet ownership may be better known, monitored and managed.

Ultimately, the burden of safe and responsible pet ownership should be shared. While public awareness is crucial, the key to a sustainable pet trade is mutual partnership between pet owner communities and governments. This is particularly important as pet sales and trade shift further to an online environment.

The new west: why Republicans blocked public land management

The Guardian - Mon, 2017-07-03 02:19

As ‘permanent tourists’ move to the western US, the oil and gas-captured Republican party is fighting to keep locals out of managing public lands

A year ago, residents of Yucca Valley, California, along with Bureau of Land Management (BLM) and US Forest Service officials, filled the town’s community center for a public meeting about the Sand to Snow National Monument. Designated early in 2016 by Barack Obama – and now under review for resizing by the Trump administration – the monument spans from the desert near Yucca Valley to the San Bernardino mountains about an hour east of Los Angeles.

Residents wanted to know what would change once their back-yard BLM land was converted into a national monument. Would the monument prohibit public access? Would it mean an end for hunting? What would it do for protecting area wildlife? Even those who had opposed Obama’s creation of Sand to Snow and the nearby Mojave Trails national monument came to the meeting, asking how they could have their voices heard in planning processes.
