Remote Indigenous Australia’s ecological economies give us something to build on


Jon Altman, Australian National University

Land titling in Australia has undergone a revolutionary shift over the past four decades. The return of diverse forms of title to Indigenous Australians has produced some semblance of land justice. About half the continent is now held under some form of Indigenous title.

Forms of title range from inalienable freehold title to non-exclusive (or shared) native title. Much of this estate is in northern Australia, as this recent map shows.

Another map from 2014 shows over 1,000 discrete Indigenous communities and the division between north and south.

What’s different about these lands?

These lands and their populations have some unusual features.

First, the lands are extremely remote and relatively undeveloped in a capitalist “extractive” sense. These are the largest relatively intact savannah landscapes in Australia — and possibly the world.

Much of this estate is included in the National Reserve System as Indigenous Protected Areas because of its high environmental and cultural values, according to International Union for Conservation of Nature (IUCN) criteria.

These areas still face threats from invasive animal and plant species, bushfires and increasingly extreme heat. These threats will lead to further species extinctions.

Indigenous Protected Area management plans address these threats to ensure biodiversity and cultural values are at best restored or maintained, at worst not eroded.

Second, parts of these lands in the wet-dry tropics are valuable as sources of emissions avoidance and carbon storage.

Many groups are paid through offset markets and voluntary agreements to reduce overall emissions. There are emerging options for payment for long-term carbon storage – between 25 and 100 years.

These lands have some of the world’s highest solar irradiance. Multi-billion-dollar solar and wind/solar/green hydrogen facilities are being developed.

Third, the Indigenous owners and majority inhabitants are among the poorest Australians. Only 35% of Aboriginal adults in very remote Australia are formally employed. Over 50% of Indigenous people in these areas live below the poverty line.

Such poverty is explained partly by past colonisation and associated social exclusion and neglect, geographic isolation from market capitalism and labour markets, and different priorities.

Having legally proven continuity of customs, traditions and connection to reclaimed ancestral lands, landowners generally look to care for their country. They use its natural resources for domestic non-commercial purposes as allowed by law.

But Indigenous people continually struggle to inhabit these lands. Their dispersed small settlements range from townships to homelands. Government support is minimal and policy intentionally discouraging.

The problem with official development models

Since federation, many government policy proposals to “develop the north” have sought to replicate the economic growth trajectory of the temperate south. Such plans are based on state-sanctioned, often environmentally damaging, market capitalism.

The latest version is the 2015 Our North, Our Future white paper, released after a parliamentary inquiry. In submission 136, Francis Markham and I asked, “developing whose north for whom and in what way?” We pointed out 48% of the north’s 3 million square kilometres was under Indigenous title at that time, and Indigenous ideas about the land are often very different from those of the government and corporate, mainly extractive, interests.

Four years on, a Senate select inquiry is examining how the Our North, Our Future agenda is progressing. A specific reference to First Nations people has been added. In submission 13, we highlighted four fundamental changes over the past five years.

  1. the Indigenous land share of northern Australia has grown to 60%

  2. Indigenous people are living in deeper poverty partly due to punitive changes to income-support arrangements

  3. growing scientific consensus that global warming will have escalating negative impacts on northern Australia

  4. slowing population growth suggests the white paper’s goal of a population of 4–5 million by 2060 (from just over 1 million now) lacks realism.

We are at a critical crossroads in policy thinking about northern Australia.

The dominant approach sees it as ripe for capitalist development, extraction and associated economic growth, irrespective of environmental consequences. Corporate pressure to undertake risky fracking for oil and gas and to develop industrial-scale agriculture and aquaculture projects epitomises such thinking.

The zero-emissions alternative

The holistic focus of ecological economics informs an alternative approach. It’s based on the tenet that everything connects to everything else: the economy is embedded in society and society is embedded in the environment, the natural order.

This line of reasoning resonates with the focus of many Indigenous landowners on the need to nurture kin, ancestral country and living, natural resources.

Ecological economics distinguishes between economic growth that depletes non-renewable resources irrespective of environmental harm, and forms of development that focus on human well-being, cultural and environmental values.

What is ‘ecological economics’ and why do we need to talk about it?


Development in the north might take many transformational forms as we strive for a zero-emissions economy.

Economist Ross Garnaut discusses the potential of a zero-emissions economy in Australia.

Indigenous-titled and peopled lands are well positioned to drive this in three proven ways:

  1. by intensifying projects that reduce emissions and sequester carbon
  2. by increasing efforts to conserve biodiversity by managing and potentially reversing impacts of invasive species
  3. by becoming key players in the renewables sector through massive projects for domestic energy use and export.

The same landscapes can be used for sustainable wildlife harvesting for food and diverse forms of cultural production for income. These uses accord with Indigenous tradition and leave minimal environmental footprints.

Policy and practice must be informed by the environmental perspectives of Indigenous landowners, which are highly compatible with the core concepts of ecological economics.

In these ways, the North could emerge as a powerhouse region beyond current imaginaries. The climate crisis makes this transformation essential.

As ecological economies, remote Indigenous lands could deliver sustainable livelihoods to Indigenous people and contribute significantly to a zero-emissions economy of critical benefit to national and global communities.The Conversation

What is ‘ecological economics’ and why do we need to talk about it?



Ecological economics focuses on sustainability and development, rather than the traditional economic concerts of efficiency and growth.

This article is part of a series on rebalancing the human–nature interactions that are central to the study and practice of ecological economics, which is the focus of the 2019 ANZSEE Conference in Melbourne later this month.


As environmental crises and the urgency to create ecological sustainability escalate, so does the importance of ecological economics. This applied, solutions-based field of studies is concerned with sustainability and development, rather than efficiency and growth. Also, given that cities account for 70-80% of global economic activity and associated resource use, emissions and waste, they are central to finding solutions to the challenge of sustainability.

Ecological economics recognises local to global environmental limits. It ranges from research for short-term policy and local challenges through to long-term visions of sustainable societies. Ecological economists also consider global issues such as carbon emissions, deforestation, overfishing and species extinctions.

Core concepts

You’re probably familiar with some core concepts of ecological economics. These include “steady-state economies”, “carrying capacity”, “ecological footprints” and “environmental justice”.

Nicholas Georgescu-Roegen was one of the first economists to argue that an economy faces limits to growth as a result of resource depletion.

A steady-state economy is both relatively stable and respects ecological limits. Drawing on the work of mathematician and economist Nicholas Georgescu-Roegen, economist Herman Daly elaborated the model, editing a 1973 anthology, Toward a Steady-State Economy.

In 1990, Daly co-founded the International Society of Ecological Economics (ISEE). It had three key principles:

  • the human economy is embedded in nature, and economic processes are actually biological, physical and chemical processes and transformations

  • ecological economics is a meeting place for researchers committed to environmental issues

  • ecological economics requires transdisciplinary work to describe economic processes in relation to physical reality.

Joshua Farley, who has worked with Daly, discusses some of these principles in an opening address to the Australia New Zealand Society of Ecological Economics (ANZSEE) conference at RMIT University later this month.

In a partnership program of several North American universities, Farley teaches Economics for the Anthropocene postgraduates. They apply ecological economics to “real-world environmental solutions”. Some will talk at the conference about their research.

Today overconsumption is measured against Earth’s carrying capacity.

William Rees and Mathis Wackernagel developed the related concept of the ecological footprint. It’s an indicator of the ecological impacts of everyday activities and practices.

Ecological footprints are useful ways for industries, governments and people to assess which practices we need to reduce to keep within the limits of Earth’s regenerative capacity.

Issues of environmental justice in Australia include:

A new kind of economics

Ecological economics partly developed from frustration with the narrowness of environmental and resource economics. These approaches apply mainstream economics to the environment. In doing so, they fail to incorporate critical environmental concerns that arise with inputs, outputs and waste.

Beyond GDP: are there better ways to measure well-being?


In addition, ecological economists have a broader view about what “progress” is and how to measure it. Ecological econonomists are more sceptical about how much human-made capital improves on the benefits we get from nature. Critically, they ask: “How useful is it to put a monetary value on nature?”

Ecological economist Clive Hamilton discusses that question in the case of Coronation Hill in Kakadu National Park. He argues that market-based assessments such as “willingness to pay” favour market-based solutions. Similarly, Brian Coffey highlights the conundrum of monetising ecological values:

I would rather ask “why is nature important?” and “how can we live with, and within, it?”

Despite this, certain ecological economists use monetary data to make powerful ecological statements. For instance, Ida Kubiszewski and her co-authors surveyed land uses under different future scenarios. They concluded that continuing business as usual could wipe out a third of the value of Asia-Pacific ecosystems by 2050.

Solutions for sustainable and just futures

In short, ecological economics has contributors from diverse disciplinary and professional backgrounds.

Presenters to the ANZSEE conference of course include ecologists and economists. But there are also social and physical scientists, sociologists, philosophers, historians, planners and sustainability experts.

Sustainability expert Samuel Alexander speaks about living well with degrowth. Others argue that a climate-safe world requires radical forms of economics.

Attorney-General Christian Porter targets Market Forces in push against environment groups

The government has the activist group Market Forces squarely in its sights as it considers ways to stop environmental organisations persuading financial and other businesses to boycott companies in the mining sector.

It is also targeting funders of class actions, in its proposed crackdown on those running climate change campaigns that hit firms.

Attorney-General Christian Porter singled out Market Forces in a Monday statement that said he was co-ordinating advice across several portfolios on what could be done to protect resource businesses from such activism.

Prime Minister Scott Morrison on Friday condemned “an escalating trend towards a new form of secondary boycotts” which had potentially serious economic consequences, especially for regional economies.

“Environmental groups are targeting businesses and firms who provide goods or services to firms they don’t like, especially in the resources sector,” Morrison told the Queensland Resources Council.

Market Forces was launched in 2013, and is affiliated with Friends of the Earth. The organisation’s website says it “exposes” institutions, such as banks, superannuation funds and governments that are financing environmentally destructive projects.

Market Forces has lobbied heavily against Adani’s proposed Carmichael mine in central Queensland. Its website lists the companies it says have links to the project, and asks supporters to contact those companies to demand they cut ties.

The organisation’s chief executive Julien Vincent hit back at the government on Monday, saying that where it saw something it did not like “its response is to get it shut down”.

“We simply allow people to make informed decisions on who they do business with,” Vincent said.

“That’s a right that we thought, until recently, that this government was prepared to uphold”.

But Porter said it was “simply not OK” for any Australian business to be targeted by groups seeking to do it financial harm “when all they are doing is working in an industry like mining and resources that a small number of domestic and international activists have an ideological objection to.

“There are a growing number of examples where we have seen radical activist groups like Market Forces that try and impose their political will on companies across the country through widespread, co-ordinated harassment and threats of boycotts,” he said.

The government was looking at multiple options, across portfolios, Porter said, and the work would be prepared urgently.

Attorney-General Christian Porter has announced the government will try to prevent activist groups from initiating boycotts against companies.

The government was also considering regulatory action against “the growing presence of litigation funders who are receiving disproportionately large shares of payments in class action litigation which is becoming increasingly politicised by a focus on companies that operate in the mining and resources sector”.

Casting the net even wider, Porter said the government would consider other areas of activists’ “lawfare” which was “designed to delay, frustrate and cause unnecessary expense to mining and other legitimate commercial projects and businesses”.

Secondary boycotts are already outlawed under the competition and consumer legislation but there is an exemption where the dominant reason is for environmental or consumer protection.

An obvious course for the government would be to seek to remove the exemption.
Another option would be to remove the tax deductibility status of groups.

Labor has accused Morrison of “virtue signalling” in his planned attack on activist groups.The Conversation

Our nature laws are being overhauled. Here are 7 things we must fix

Environment Minister Sussan Ley yesterday announced a ten-yearly review of Australia’s national environmental laws. It could not come at a more critical time, as the environment struggles under unprecedented development pressures, climate change impacts and a crippling drought.

The laws, formally known as the Environmental Protection and Biodiversity Conservation (EPBC) Act, have been in place for 20 years.

Environment laws have failed to tackle the extinction emergency. Here’s the proof


Announcing the review, Ley said it would “tackle green tape” and reduce delays in project approvals. She said the laws must remain “fit for purpose” as our environment changes.

Serious declines in most biodiversity indicators strongly suggest the laws are not fit for purpose. Some 7.7 million hectares of endangered species habitat has been destroyed since the Act was established and the lists of threatened and endangered species continue to grow.

The review should ensure Australia’s environmental law achieves what it was designed to do – protect our precious natural places.

The list below reflects the EPBC Act priorities of 70 environmental lawyers and practitioners who were polled by the National Environmental Law Association. Collectively, they have more than 500 years experience of the Act’s operation.

1. Independent decisions with clear criteria

Under the laws, proponents of activities likely to have big impacts on so-called “matters of national environmental significance” must get federal approval. The minister or a representative makes this decision and, in the overwhelming majority of cases, grants approval.

This approval power should be vested in an independent body to take the politics out of decisions. Criteria for deciding on approvals should be clearer, including thresholds for when applications must be refused on environmental grounds.

2. Take stock of cumulative impacts

A search of the EPBC Act will not find any reference to cumulative impacts, or the need to consider whether approval of one proposal is likely to lead to a raft of new projects being proposed. There is little scope to consider cumulative impacts that might happen in future — only when a new proposal constitutes the straw that breaks the camel’s back.

The Act must do better at considering both how proposed activities and future plans will interact, and the background processes of environmental change and decline.

3. Provide funds for proper enforcement

Improving the content of the Act is one thing, but monitoring, compliance and enforcement are critical. There is little point imposing tough conditions if no one is there to ensure they are met. This demands an ongoing sustainable funding base that is not dependent on political budget priorities.

4. Better data and transparency

Access to information about environmental decisions is essential for good governance. Not all documents and decisions are publicly available. It is very difficult to track down detailed aspects of approval conditions – for example, the detail of the groundwater management and monitoring plan for the Adani coal mine. This is especially important when the department’s capacity to oversee compliance is so constrained.

Tasmania’s Tarkine needs a strategic plan


The Act should consider the need for public registers of all documents and data collected as part of decision-making and monitoring processes, including decisions, approvals, conditions, offset locations, compliance reports and monitoring data.

5. Expand scope of national environmental impact assessment

Commonwealth involvement in environmental approvals is limited to specific “matters of national environmental significance”. Land clearing and climate change are not included in the list of such matters, and are usually considered under state laws.

This means activities that may damage native vegetation or lead to rising emissions are only scrutinised under federal law if they might affect other things, such as threatened species or world heritage places.




Read more:
Land clearing on the rise as legal ‘thinning’ proves far from clear-cut


Also, the Act only seeks to protect water resources when the proposed project is a large coal mine or coal seam gas venture. New triggers are needed to require federal assessment and approval for all activities that might significantly affect water, native vegetation and climate change.

6. Deal with land clearing

Habitat loss is recognised as the primary driver of species decline in Australia. Rates of land clearing have increased dramatically in recent years, despite the operation of the Act.

Stronger protections are needed. These must prevent further clearing of vegetation types that are not adequately conserved in Australia’s system of protected natural areas. In cases where a proponent plans to offset damage caused by their project by restoring land elsewhere, construction should be delayed until work has begun on the restoration project and conservation benefits are occurring.

7. Make strategic assessments truly strategic

Conservation planning and environmental assessment are complex. Major new initiatives can involve interacting influences and trade-offs. The Act’s so-called “strategic assessment” process to some extent accounts for this — for example it might consider development plans across a region, rather than project-by-project.

But strategic planning must occur for a wider range of activities that may have long-term impacts on conservation: for example, the Tasmanian government’s desire to open up the Tarkine region to further mining. The planning must also better consider spatial conflicts and account for future change.

This list is just the tip of the law reform iceberg, but addressing these priorities would be a good start. With only one environmental law expert and no environmental scientist on the newly announced panel, it remains to be seen how these priorities will be addressed, if at all.The Conversation

Why a sense of kinship is key to caring about the living world



Framing nature in terms of kinship can motivate people to care about the loss of biodiversity.

Matthew Hall, Victoria University of Wellington

Leading thinkers in environmental economics and conservation are asking a pressing question. Why are we ignoring the destruction of the living world?

Recently, the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) published a global assessment of biodiversity that set out alarming statistics: a million species at threat of extinction, 75% of terrestrial environments severely altered by human activity, and a 30% reduction in global habitat integrity.

Despite all this, practical solutions to redress an ecological crisis — land use and economic reform, action on climate change and improvements to environmental governance — are not prioritised. One key reason for this is how we frame our relationship to the living world.

Instrumental nature

Our prevailing relationship with nature is instrumental – that is, we predominantly frame the living world as a set of natural resources, apart from humans, for our privileged use.

Such framing is so deeply embedded, and our material dependence on nature so total, that it can seem strange even to question the idea of nature as natural resource. In Western nations, this position has deep philosophical and religious roots.

My latest book, The Imagination of Plants, highlights the role of the creation story in Genesis and the philosophy of Aristotle in rendering plants, the living beings that make up the visible bulk of most terrestrial ecosystems, as existing for the sake of animals, and both for the sake of humans.

Do passages in the Bible justify cutting down forests?


Such accounts have powerfully shaped a human-centred, utility-based worldview that has silenced the needs of plants and animals. They form the philosophical basis of our claims to “own” other species.

If plants and animals exist for the sake of humans, why take action to conserve them when they’re not useful? Why care when their numbers are going down, as long as we can still get what we materially need from them?

Conservation concepts and strategies that place the living world within this frame, including ideas of natural capital, ecosystem services and the protection of the living world for our enlightened self-interest, are destined to fail because they do not address this underlying framing. Indeed, as researchers have pointed out, by not addressing such framing they perpetuate the very drivers of biodiversity loss.

Intrinsic value

Environmental thinkers have warned for decades that such a view of nature is at the root of our ecological crisis. More recent research has argued against this instrumental view, criticising its value as a basis for conservation action.

Since the 1980s, discussions of the intrinsic value of nature – “valuing it for what it is, not only what it does” – have happened across a number of environmental disciplines. This led to the Convention on Biological Diversity (CBD), founded on the cornerstone of the intrinsic value of biological diversity.

In some countries, such as New Zealand, the concept of intrinsic value appears in major pieces of resource management and conservation legislation. It has been instrumental in recent legal battles over land use.

Supreme Court ruling on NZ’s largest irrigation dam proposal respects conservation law and protected land


Recent work by environmental philosopher Michael Paul Nelson shows people acknowledge the intrinsic value of nature. He argues that the only reason we make decisions inconsistent with this value is because we don’t believe the general populace shares this belief.

But the concept of intrinsic value does not demand a move away from a dominant use-based frame. In the preamble of the CBD itself, intrinsic values sit alongside a raft of use-based values, including economic, scientific, educational, cultural and aesthetic values. The power of the use-based frame dominates the concept of intrinsic value.

All our relations

There is an alternative to the dichotomy of a purely instrumental relationship and the concept of intrinsic value.

In many Indigenous cultures, such relationships are built on fundamental kinship with the living world, a kinship that actually blurs and subverts the very concepts of nature and culture.

Within these kinship relationships, the needs and capacities of living beings are acknowledged, not left in the background. This is what the late anthropologist Deborah Bird Rose called the Indigenous ethic of connection, or what is also called kincentric ecology.

Kinship offers a way of connecting to nature that acknowledges our need to use plants and animals, but constructs relationships beyond use. Where the concept of intrinsic value can be difficult to engage with, kinship relationships naturally extend to care, respect and responsibility.

Framing nature in terms of kinship can motivate people to care and make the loss of the living world real for people. Ever since Darwin’s book, On the Origin of Species, science has known of our fundamental kinship with nature. Yet we don’t frame (or live with) nature in a way that honours this.

A recent example gives me hope. At the school climate strike, a young Brazilian Indigenous woman addressed a crowd in New York, speaking in terms of kinship about the human children of a mother Earth, fighting to save their mother from destruction. Framing nature in terms of kinship noticeably energised the crowd of young people.

The challenge to reframe the living world in terms of kinship is massive. A good step would be to convene a human-nature kinship platform as a way of influencing the UN Biodiversity Conference in China next year. Another step could be to enshrine our fundamental kinship with other species in all major environmental governance frameworks, including the CBD and national environmental legislation.

Both could provide the springboard for us to undergo the hard work of talking about, and living with, other species in ways that acknowledge them as our earthly relations.The Conversation

Friday essay: thinking like a planet – environmental crisis and the humanities


Tom Griffiths, Australian National University

Many of us joined the Global Climate Strike on Friday, 20 September, and together we constituted half a million Australians gathering peacefully and walking the streets of our cities and towns to protest at government inaction in the face of the gravest threat human civilisation has faced.

It was a global strike, but its Australian manifestation had a particular twist, for our own federal government is an international pariah on this issue. We have become the Ugly Australians, led by brazen climate deniers who trash the science and snub the UN Climate Summit.

Government politicians in Canberra constantly tell us the Great Barrier Reef is fine, coal is good for humanity, Pacific islands are floating not being flooded, wind turbines are obscene, power blackouts are due to renewables, “drought-proofing” is urgent but “climate-change” has nothing to do with it, science is a conspiracy, climate protesters are a “scourge” who deserve to be punished and jailed, the ABC spins the weather, the Bureau of Meteorology requires a royal commission, the United Nations is a bully, if we have to have emissions targets, well, we are exceeding them, and Australia is so insignificant in the world it doesn’t have to act anyway.

It’s a wilful barrage of lies, an insult to the public, a threat to civil society, and an extraordinary attack on our intelligence by our own elected representatives.

The international Schools4Climate movement is remarkable because it is led by children, teenagers still at school advocating a future they hope to have. I can’t think of another popular protest movement in world history led by children. This could be a transformative moment in global politics; it certainly needs to be. The active presence of so many engaged children gave the rally a spirit and a lightness in spite of its grim subject; there was a sense of fun, a family feeling about the occasion, but there was a steely resolve too.

A girl in a school uniform standing next to me at the rally held a copy of George Orwell’s 1984 in her hands. Many of the people around me would normally expect to see in the 22nd century. Their power, paradoxically, is they are not voters. They didn’t elect this government! They are protesting not just against the governments of the world but also against us adults, who did elect these politicians or who abide them. There was a moment at the rally when, with the mysterious organic coherence crowds possess, the older protesters stepped aside, parting like a wave, and formed a guard of honour through the centre of which the children marched holding their placards, their leadership acknowledged.

One placard declared: “You’ll die of old age; I’ll die of climate change”; another said: “If Earth were cool, I’d be in school.” One held up a large School Report Card with subject results: “Ethics X, Responsibility X, Climate Action X. Needs to try harder.” Another explained: “You skip summits, we skip school.”

In Melbourne, as elsewhere, teenagers gave the speeches; and they were passionate and eloquent. The demands of the movement are threefold: no new coal, oil and gas projects; 100% renewable energy generation and exports by 2030; and fund a just transition and job creation for all fossil-fuel workers and communities. There were also Indigenous speakers. One declared: “We stand for you too, when we stand for Country.”

There were 150,000 people in the Melbourne Treasury Gardens, a crowd so large responsive cheers rippled like a Mexican wave up the hill from the speakers. I reflected on the historical parallels for what was unfolding, recalling the Vietnam moratorium demonstrations and the marches against the first Gulf War, the Freedom Rides and the civil rights movement, the Aboriginal Tent Embassy and the suffragettes’ campaigns.

Inspired by this history, we now have the Extinction Rebellion, a movement born in a small British town late last year which declares “only non-violent rebellion can now stop climate breakdown and social collapse”. Within six months, through civil disobedience, it brought central London to a standstill and the United Kingdom became the first country to declare a climate emergency. We are at a political tipping point.

In Australia, the result of this year’s election tells us there is no accountability for probably the most dysfunctional and discredited federal government in our history, and now we are left with a parliament unwilling to act on so many vital national and international issues. The 2019 federal election was no status quo outcome, as some political commentators have declared. Rather, it was a radical result, revealing deep structural flaws in our parliamentary democracy, our media culture and our political discourse. For me it ranks with two other elections in my voting lifetime: the “dark victory” of the 2001 Tampa election, and the 1975 constitutional crisis. Like those earlier dates, 2019 could shape and shadow a generation. It is time to get out on the streets again.

Skolstrejk för klimatet

The founder, symbol and the voice of the School Strike movement is, of course, Greta Thunberg. It is just over a year since August 2018 when she began to spend every Friday away from class sitting outside the Swedish parliament with a handmade sign declaring “School Strike for the Climate”.

When she told her parents about her plans, she reported “they weren’t very fond of it”. Addressing the UN Climate Change Conference in December 2018, she said: “You are not mature enough to tell it like it is. Even that burden you leave to your children.” Thunberg quietly invokes the carbon budget and the galling fact there is already so much carbon in the system “there is simply not enough time to wait for us to grow up and become the ones in charge.”

In late September, Thunberg gave a powerful presentation at the UN Climate Summit; Richard Flanagan compared her 495-word UN speech to Abraham Lincoln’s 273-word Gettysburg Address. It’s a reasonable parallel that reaches for some understanding of the enormity of this political moment.

It is sickening to see the speed with which privileged old white men have rushed to pour bile on this young woman. Donald Trump and Vladimir Putin quickly recognised her power and sought to neutralise and patronise her. Scott Morrison chimed in. Australia’s locker room of shock jocks laced the criticism with some misogyny. It’s amazing how they froth at the mouth about a calm and articulate schoolgirl. They are all – directly or indirectly – in the pockets of the fossil fuel industry.

Misogyny, male rage and the words men use to describe Greta Thunberg


Denialism

Denialism is worthy of study. I don’t mean the conscious and fraudulent denialism of politicians and shock-jocks such as those I’ve mentioned. That’s pretty simple stuff – lies motivated by opportunism, greed and personal advancement, and funded by the carbon-polluting industries. It is appalling but boring.

There are more interesting forms of denialism, such as the emotional denialism we all inhabit. Emotional denialism in the face of the unthinkable can take many forms – avoidance, hope, anxiety, even a kind of torpor when people truly begin to understand what will happen to the world of their grandchildren. We are all prone to this willing blindness and comforting self-delusion. Overcoming that is our greatest challenge.

And there is a third kind of denialism that should especially interest scholars. It is when some of our own kind – scholars trained to respect evidence – fashion themselves as sceptics, but are actually dogged contrarians.

One example is Niall Ferguson, a Scottish historian and professor of history at Harvard University, who calls climate science “science fiction” and recently joined the ranks of old, white, privileged men commenting on the appearance of Greta Thunberg. I’m not arguing here with Ferguson’s politics – he is an arch-conservative and I do disagree with his politics, but I also believe engaged, reflective politics can drive good history.

Rather, Ferguson’s disregard for evidence and neglect of science and scholarship attracts my attention. His understanding of climate science and climate history is poor: in a recent article in the Boston Globe he assumed the Little Ice Age started in the 17th century, whereas its beginning was three centuries earlier.

How does a trained scholar, a professor of history, get themselves in this ignominious position? For Ferguson, contrarianism has been a productive intellectual strategy – going against the flow of fashion is a good scholarly instinct – but on climate change his politics and the truth have steadily travelled in different directions and caught him out. We can say the same of Geoffrey Blainey, another successful contrarian who has cornered himself on climate change. Like Ferguson he appears uninterested in decades of significant research in environmental history – and thus his healthy scepticism has morphed into foolish denialism.

Denialism matters because all kinds of it have delayed our global political response to climate change by 30 years. In those critical decades since the 1980s, when humans first understood the urgency of the climate crisis, total historical carbon emissions since the industrial revolution have doubled. And still global emissions are rising, every year.

The physics of this process are inexorable – and so simple, as Greta would say, even a child can understand. We are already committing ourselves to two degrees of warming, possibly three or four. Denialists have, knowingly and with malice aforethought, condemned future generations to what Tim Flannery calls a “grim winnowing”. Flannery wrote recently “the climate crisis has now grown so severe that the actions of the denialists have turned predatory: they are now an immediate threat to our children.”

The gloves are off: ‘predatory’ climate deniers are a threat to our children


The history of denialism alerts us to a disastrous paradox: the very moment, in the 1980s, when it became clear global warming was a collective predicament of humanity, we turned away politically from the idea of the collective, with dire consequences. Naomi Klein, in her latest book On Fire, elucidates this fateful coincidence, which she calls “an epic case of historical bad timing”: just as the urgency of action on climate change became apparent, “the global neoliberal revolution went supernova”.

Unfettered free-market fanaticism and its relentless attack on the public sphere derailed the momentum building for corporate regulation and global cooperation. Ten years ago, thoughtful, informed climate activists could still argue that we can decouple the debates about economy and democracy from climate action. But now we can’t. At the 2019 election, Australia may have missed its last chance for incremental political change. If the far right had not politicised climate change and delayed action for so long then radical political transformation would not necessarily have been required. But now it will be, and it’s coming.

A great derangement

We are indeed living in what we might call “uncanny times”. They are weird, strange and unsettling in ways that question nature and culture and even the possibility of distinguishing between them.

The Bengali novelist Amitav Ghosh uses the term “uncanny” in his book The Great Derangement: Climate Change and the Unthinkable, published in 2016. The planet is alive, says Ghosh, and only for the last three centuries have we forgotten that. We have been suffering from “the great derangement”, a disturbing condition of wilful and systematic blindness to the consequences of our own actions, in which we are knowingly killing the planetary systems that support the survival of our species. That’s what’s uncanny about our times: we are half-aware of this predicament yet also paralysed by it, caught between horror and hubris.

We inhabit a critical moment in the history of the Earth and of life on this planet, and a most unusual one in terms of our own human history. We have developed two powerful metaphors for making sense of it. One is the idea of the Anthropocene, which is the insight we have entered a new geological epoch in the history of the Earth and have now left behind the 13,000 years of the relatively stable Holocene epoch, the period since the last great ice age. The new epoch recognises the power of humans in changing the nature of the planet, putting us on a par with other geophysical forces such as variations in the earth’s orbit, glaciers, volcanoes and asteroid strikes.

The other potent metaphor for this moment in Earth history is the Sixth Extinction. Humans have wiped out about two-thirds of the world’s wildlife in just the last half-century.

Let that sentence sink in. It has happened in less than a human lifetime. The current extinction rate is a hundred to a thousand times higher than was normal in nature. There have been other such catastrophic collapses in the diversity of life on Earth: five of them – sudden, shocking falls in the graph of biodiversity separated by tens of millions of years, the last one in the immediate aftermath of the asteroid impact that ended the age of the dinosaurs 65 million years ago. We now have to ask ourselves: are we inhabiting – and causing – the Sixth Extinction?

These two metaphors – the Anthropocene and the Sixth Extinction – are both historical concepts that require us to travel in geological and biological time across hundreds of millions of years and then to arrive back at the present with a sense not of continuity but of discontinuity, of profound rupture. That’s what Earth system science has revealed: it’s now too late to go back to the Holocene. We’ve irrevocably changed the Earth system and unwittingly steered the planet into the Anthropocene; now we can’t take our hand off the tiller.

Earth is alive

I’ve been considering metaphors of deep time, but what of deep space? It has also enlarged our imaginations in the last half century. In July this year, we commemorated the 50th anniversary of the Moon landing. I was 12 at the time of the Apollo 11 voyage and found myself in a school debate about whether the money for the Moon mission would be better spent on Earth. I argued it would be, and my team lost.

But what other result was allowable in July 1969? Conquering the Moon, declared Dr Wernher von Braun, Nazi scientist turned US rocket maestro, assured man of immortality. I followed the Apollo missions with a sense of wonder, staying up late to watch the Saturn V launch, joining my schoolmates in a large hall with tiny televisions to witness Armstrong take his Giant Leap, and saving full editions of The Age newspaper reporting those fabled days.

The rhetoric of space exploration was so future-oriented that NASA did not foresee Apollo’s greatest legacy: the radical effect of seeing the Earth. In 1968, the historic Apollo 8 mission launched humans beyond Earth’s orbit for the first time, into the gravitational power of another heavenly body. For three lunar orbits, the three astronauts studied the strange, desolate, cratered surface below them and then, as they came out from the dark side of the Moon for the fourth time, they looked up and gasped:

Frank Borman: Oh my God! Look at that picture over there! Here’s the Earth coming up. Wow, that is pretty!

Bill Anders: Hey, don’t take that, it’s not scheduled.

They did take the unscheduled photo, excitedly, and it became famous, perhaps the most famous photograph of the 20th century, the blue planet floating alone, finite and vulnerable in space above a dead lunar landscape. Bill Anders declared: “We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.”

In his fascinating book, Earthrise (2010), British historian Robert Poole explains this was not supposed to happen. The cutting edge of the future was to be in space. Leaving the Earth’s atmosphere was seen as a stage in human evolution comparable to our amphibian ancestor crawling out of the primeval slime onto land.

Furthermore, this new dominion was seen to offer what Neil Armstrong called a “survival possibility” for a world shadowed by the nuclear arms race. In the words of Buzz Lightyear (who is sometimes hilariously confused with Buzz Aldrin), the space age looked to infinity and beyond!

Earthrise had a profound impact on environmental politics and sensibilities. Within a few years, the American scientist James Lovelock put forward “the Gaia hypothesis”: that the Earth is a single, self-regulating organism. In the year of the Apollo 8 mission, Paul Ehrlich published his book, The Population Bomb, an urgent appraisal of a finite Earth. British economist Barbara Ward wrote Spaceship Earth and Only One Earth, revealing how economics failed to account for environmental damage and degradation, and arguing that exponential growth could not continue forever.

Earth Day was established in 1970, a day to honour the planet as a whole, a total environment needing protection. In 1972, the Club of Rome released its controversial and influential report The Limits to Growth, which sold over 13 million copies. In their report, Donella Meadows and Dennis Meadows wrestled with the contradiction of trying to force infinite material growth on a finite planet. The cover of their book depicted a whole Earth, a shrinking Earth.

Earth systems science developed in the second half of the 20th century and fostered a keen understanding of planetary boundaries – thresholds in planetary ecology – and the extent to which they were being violated. The same industrial capitalism that unleashed carbon enabled us to extract ice cores from the poles and construct a deep history of the air. The fossil fuels that got humans to the Moon, it now emerged, were endangering our civilisation.

The American ecologist and conservationist Aldo Leopold wrote in 1949 of the need for a new “land ethic”. Leopold envisaged a gradual historical expansion of human ethics, from the relations between individuals to those between the individual and society, and ultimately to those between humans and the land. He hoped for an enlargement of the community to which we imagine ourselves belonging, one that includes soil, water, plants and animals.

In his book of essays, A Sand County Almanac, there is a short, profound reflection called “Thinking like a mountain.” He tells of going on the mountain and shooting a wolf and her cubs and then watching “a fierce green fire” die in her eyes.

He shot her because he thought fewer wolves meant more deer, but over the years he watched the overpopulated deer herd die as the wolfless mountain became a dustbowl. Leopold came to understand the beautiful delicacy of the ecosystem, which holds “a deeper meaning, known only to the mountain itself. Only the mountain has lived long enough to listen objectively to the howl of a wolf.”

Today, 70 years after Leopold’s philosophical leap, we are being challenged to scale up from a land ethic to an earth ethic, to an environmental vision and philosophy of action that sees the planet as an integrated whole and all of life upon it as an interdependent historical community with a common destiny, to think not only like a mountain, but also like a planet. We are belatedly remembering the planet is alive.

Climate science is climate history

Climate change and ecological crisis are often seen as purely scientific issues. But as humanities scholars we know all environmental problems are at heart human ones; “scientific” issues are pre-eminently challenges for the humanities. Historical perspective can offer much in this time of ecological crisis, and many historians are reinventing their traditional scales of space and time to tell different kinds of stories, ones that recognise the agency of other creatures and the unruly power of nature.

There is a tendency among denialists to lazily use history against climate science, arguing for example “the climate’s always changing”, or “this has happened before”. Good recent historical scholarship about the last 2000 years of human civilisation is so important because it corrects these misunderstandings. That’s why it’s so disappointing when celebrity historians like Niall Ferguson and Geoffrey Blainey seek to represent their discipline by ignoring the work of their colleagues.

Climate science is unavoidably climate history; it’s an empirical, historical interpretation of life on earth, full of new insights into the impact and predicament of humanity in the long and short term. Recent histories of the last 2,000 years have been crucial in helping us to appreciate the fragile relationship between climate and society, and why future average temperature changes of more than 2℃ can have dire consequences for human civilisation.

We now have environmental histories of antiquity, and of medieval and early modern Europe – studies casting new light on familiar human dramas, including the decline and fall of the Roman Empire, the Black Death in the medieval period, and the unholy trinity of famine, war and disease during the Little Ice Age of the 17th century.

These books draw on natural as well as human history, on the archives of ice, air and sediment as well as bones, artefacts and documents. And then there is John McNeill’s history of the 20th century, Something New Under the Sun, which argues “the human race, without intending anything of the sort, has undertaken a gigantic uncontrolled experiment on earth”.

These new histories encompass the planet and the human species, and provocatively blur biological evolution and cultural history (Yuval Noah Harari’s “brief history of humankind”, Sapiens, is a bestselling example). They investigate the vast elemental nature of the heavens as well as the interior, microbial nature of human bodies: nature inside and out, with the striving human as a porous vessel for its agency.

In Australia, we have outstanding new histories linking geological and human time, such as Charles Massy’s Call of the Reed Warbler: A New Agriculture – A New Earth and Tony Hughes d’Aeth’s Like Nothing on This Earth: A Literary History of the Wheatbelt.

Australians seem predisposed to navigate the Anthropocene. I think it’s because the challenge of Australian history in the 21st century is how to negotiate the rupture of 1788, how to relate geological and human scales, how to get our heads and hearts around a colonial history of 200 years that plays out across a vast Indigenous history in deep time.

From the beginnings of colonisation, Australia’s new arrivals commonly alleged Aboriginal people had no history, had been here no more than a few thousand years, and were caught in the fatal thrall of a continental museum. But from the early 1960s, archaeologists confirmed what Aboriginal people had always known: Australia’s human history went back aeons, into the Pleistocene, well into the last ice age. In the late 20th century, the timescale of Australia’s human history increased tenfold in just 30 years and the journey to the other side of the frontier became a journey back into deep time.

Friday essay: when did Australia’s human history begin?


It’s no wonder the idea of big history was born here, or environmental history has been so innovative here. This is a land of a radically different ecology, where climatic variation and uncertainty have long been the norm – and are now intensifying. Australia’s long human history spans great climatic change and also offers a parable of cultural resilience.

Even the best northern-hemisphere scholars struggle to digest the implications of the Australian time revolution. They often assume, for example, “civilisation” is a term associated only with agriculture, and still insist 50,000 years is a possible horizon for modern humanity. Australia offers a distinctive and remarkable human saga for a world trying to come to terms with climate change and the rupture of the Anthropocene. Living on a precipice of deep time has become, I think, an exhilarating dimension of what it means to be Australian. Our nation’s obligation to honour the Uluru Statement is not just political; it is also metaphysical. It respects another ethical practice and another way of knowing.

Earthspeaking

In 2003, in its second issue, Griffith Review put the land at the centre of the nation. The edition was called Dreams of Land and it’s full of gold, including an essay by Ian Lowe sounding the alarm on the ecological and climate emergency – which reminds us how long we’ve had these eloquent warnings. As Graeme Davison said on launching the edition in December 2003:

At the threshold of the 21st century Australia has suddenly come down to earth. […] Earth, water, wind and fire are not just natural elements; they are increasingly the great issues of the day.

It is instructive to compare this issue of the Griffith Review, with the edition entitled Writing the Country, published 15 years later last summer. In the intervening decade and a half, sustainability morphed into survival, native title into Treaty and the Voice, the Anthropocene infiltrated our common vocabulary, the republic and Aboriginal recognition are no longer separable, and land decisively became Country with a capital “C”. In 2003 the reform hopes of the 1990s had not entirely died, but by 2019 it’s clear the dead hand of the Howard government and its successors has thoroughly throttled trust in the workings of the state.

Perhaps the most powerful contribution in GR2 – and it was given the honour of appearing first – was an essay by Melissa Lucashenko called “Not quite white in the head”. This year’s Miles Franklin winner, Lucashenko was already in great form in 2003. Tough, poetic and confronting, the words of her essay still resonate. Lucashenko writes of “earthspeaking”.

“I am earthspeaking,” she says, “talking about this place, my home and it is first, a very small story […] This earthspeaking is a small, quiet story in a human mouth.”

“Big stories are failing us as a nation,” suggests Lucashenko. “But we are citizens and inheritors and custodians of tiny landscapes too. It is the small stories that attach to these places […] which might help us find a way through.”

I think earthspeaking is a companion to thinking like a planet. Instead of beginning from the outside with a view of Earth in deep space and deep time, earthspeaking works from the ground up; it is inside-out; it begins with beloved Country. So it is with earthspeaking I want to finish.

Four months ago I was privileged to sit in a circle with Mithaka people, the traditional Aboriginal owners of 33,000 square kilometres of the Kirrenderi/Channel Country of the Lake Eyre Basin in south-western Queensland. In 2015, the Federal Court handed down a native title consent determination for the Mithaka enabling them to return to Country. Now they have begun a process of assessing and renewing their knowledge.

I was invited to be involved because I have studied the major white writer about this region, a woman called Alice Duncan-Kemp who was born on this land in 1901 where her family ran a cattle farm, and grew up with Mithaka people who worked on the station and were her carers and teachers. Young Alice spent her childhood days with her Aboriginal friends and teachers, especially Mary Ann and Moses Youlpee, who took her on walks and taught her the names and meanings and stories that connected every tree, bird, plant, animal, rock, dune and channel.

From the 1930s to the 1960s Alice wrote four books – half a million words – about the world of her childhood and the people and nature of the Channel Country, and although she did find a wide readership, her books were dismissed by authorities, landowners and locals as “romantic” and “nostalgic” and “fictional”.

Her writing was systematically marginalised: she was a woman in cattle country, a sympathiser with Aboriginal people, she refused to ignore the violence of the frontier and she challenged the typical heroic western style of narrative. The huge Kidman pastoral company bought her family’s land in 1998, bulldozed the historic pisé homestead into the creek, threw out the collection of Aboriginal artefacts, and continues to deny Alice’s writings have any historical authenticity. Yet her books were respected in the native title process and were crucial to the Mithaka in their fight to regain access to Country.

It was very moving to be present this year when Alice’s descendants and Moses’ people met for the first time. It was not just a social and symbolic occasion: we had come together as researchers and we had work to do. Across a weekend we pored over maps and talked through evidence, combining legend, memory, oral history, letters and manuscripts, published books, archaeological studies, surveyors’ records, and even recent drone footage of the remote terrain, all with the purpose of retrieving and reactivating knowledge, recovering language and reanimating Country. We could literally map Alice’s stories back onto features of the land, with the aim of bringing it under caring attention again.

This process is going on in beloved places right across the continent. Grace Karskens and Kim Mahood write beautifully in GR63 about similar quests, and of their hope written words dredged from the archive “might again be spoken as part of living language and shared geographies.”

Earthspeaking and thinking like a planet are profoundly linked. As the Indigenous speaker at the Melbourne Climate Strike said, “We stand for you when we stand for Country.” In these frightening and challenging times, we need radical storytelling and scholarly histories, narratives that weave together humans and nature, history and natural history, that move from Earth systems to the earth beneath our feet, from the lonely, living planet spinning through space to the intimately known and beloved local worlds over which we might, if we are lucky, exert some benevolent influence.

We need them not only because they help us to better understand our predicament, but also because they might enable us to act, with intelligence and grace.

Climate Explained is a collaboration between The Conversation, Stuff and the New Zealand Science Media Centre to answer your questions about climate change.

If you have a question you’d like an expert to answer, please send it to climate.change@stuff.co.nz

There is a lot of discussion on the benefits of electric cars versus fossil fuel cars in the context of lithium mining. Please can you tell me which one weighs in better on the environmental impact in terms of global warming and why?

Electric vehicles (EVs) seem very attractive at first sight. But when we look more closely, it becomes clear that they have a substantial carbon footprint and some downsides in terms of the extraction of lithium, cobalt and other metals. And they don’t relieve congestion in crowded cities.

In this response to the question, we touch briefly on the lithium issue, but focus mainly on the carbon footprint of electric cars.

The increasing use of lithium-ion batteries as a major power source in electronic devices, including mobile phones, laptops and electric cars has contributed to a 58% increase in lithium mining in the past decade worldwide. There seems little near-term risk of lithium being mined out, but there is an environmental downside.

The mining process requires extensive amounts of water, which can cause aquifer depletion and adversely affect ecosystems in the Atacama Salt Flat, in Chile, the world’s largest lithium extraction site. But researchers have developed methods to recover lithium from water.

Turning to climate change, it matters whether electric cars emit less carbon than conventional vehicles, and how much less.

Emissions reduction potential of EVs

The best comparison is based on a life cycle analysis which tries to consider all the emissions of carbon dioxide during vehicle manufacturing, use and recycling. Life cycle estimates are never entirely comprehensive, and emission estimates vary by country, as circumstances differ.

In New Zealand, 82% of energy for electricity generation came from renewable sources in 2017. With these high renewable electricity levels for electric car recharging, compared with say Australia or China, EVs are better suited to New Zealand. But this is only one part of the story. One should not assume that, overall, electric cars in New Zealand have a close-to-zero carbon footprint or are wholly sustainable.

A life cycle analysis of emissions considers three phases: the manufacturing phase (also known as cradle-to-gate), the use phase (well-to-wheel) and the recycling phase (grave-to-cradle).

The manufacturing phase

In this phase, the main processes are ore mining, material transformation, manufacturing of vehicle components and vehicle assembly. A recent study of car emissions in China estimates emissions for cars with internal combustion engines in this phase to be about 10.5 tonnes of carbon dioxide (tCO₂) per car, compared to emissions for an electric car of about 13 tonnes (including the electric car battery manufacturing).

Emissions from the manufacturing of a lithium-nickel-manganese-cobalt-oxide battery alone were estimated to be 3.2 tonnes. If the vehicle life is assumed to be 150,000 kilometres, emissions from the manufacturing phase of an electric car are higher than for fossil-fuelled cars. But for complete life cycle emissions, the study shows that EV emissions are 18% lower than fossil-fuelled cars.

How electric cars can help save the grid


The use phase

In the use phase, emissions from an electric car are solely due to its upstream emissions, which depend on how much of the electricity comes from fossil or renewable sources. The emissions from a fossil-fuelled car are due to both upstream emissions and tailpipe emissions.

Upstream emissions of EVs essentially depend on the share of zero or low-carbon sources in the country’s electricity generation mix. To understand how the emissions of electric cars vary with a country’s renewable electricity share, consider Australia and New Zealand.

In 2018, Australia’s share of renewables in electricity generation was about 21% (similar to Greece’s at 22%). In contrast, the share of renewables in New Zealand’s electricity generation mix was about 84% (less than France’s at 90%). Using these data and estimates from a 2018 assessment, electric car upstream emissions (for a battery electric vehicle) in Australia can be estimated to be about 170g of CO₂ per km while upstream emissions in New Zealand are estimated at about 25g of CO₂ per km on average. This shows that using an electric car in New Zealand is likely to be about seven times better in terms of upstream carbon emissions than in Australia.

The above studies show that emissions during the use phase from a fossil-fuelled compact sedan car were about 251g of CO₂ per km. Therefore, the use phase emissions from such a car were about 81g of CO₂ per km higher than those from a grid-recharged EV in Australia, and much worse than the emissions from an electric car in New Zealand.

The recycling phase

The key processes in the recycling phase are vehicle dismantling, vehicle recycling, battery recycling and material recovery. The estimated emissions in this phase, based on a study in China, are about 1.8 tonnes for a fossil-fuelled car and 2.4 tonnes for an electric car (including battery recycling). This difference is mostly due to the emissions from battery recycling which is 0.7 tonnes.

This illustrates that electric cars are responsible for more emissions than their petrol counterparts in the recycling phase. But it’s important to note the recycled vehicle components can be used in the manufacturing of future vehicles, and batteries recycled through direct cathode recycling can be used in subsequent batteries. This could have significant emissions reduction benefits in the future.

So on the basis of recent studies, fossil-fuelled cars generally emit more than electric cars in all phases of a life cycle. The total life cycle emissions from a fossil-fuelled car and an electric car in Australia were 333g of CO₂ per km and 273g of CO₂ per km, respectively. That is, using average grid electricity, EVs come out about 18% better in terms of their carbon footprint.

Likewise, electric cars in New Zealand work out a lot better than fossil-fuelled cars in terms of emissions, with life-cycle emissions at about 333 g of CO₂ per km for fossil-fuelled cars and 128g of CO₂ per km for electric cars. In New Zealand, EVs perform about 62% better than fossil cars in carbon footprint terms.The Conversation
