Don’t look up! Don’t talk up! Don’t rock the status quo. Attenborough’s message upsets vested interests.

David Attenborough is experiencing what happens when society is caught in the late ‘K’ phase of the adaptive cycle. It’s an insight from complex systems science that we are all seeing play out around us every day. The insight is this: over time, vested interests and elites distort the system to maximise their wealth while simultaneously playing the system to protect their perceived entitlement. They do this through denial, obfuscation, denigration and applying the levers of power to prevent change and stop any talk about the redistribution of power.

How is David Attenborough an example of this?

Apparently the BBC has decided not to broadcast an episode of his flagship new series on British wildlife, Wild Isles, because of fears its messages on the destruction of nature and the decline of biodiversity would risk a backlash from conservative politicians and the right-wing press.

The episode in question takes a stark look at the losses of nature in the UK and what has caused the declines (loss and degradation of habitat and climate disruption). The BBC claims this episode was only intended for the network’s iPlayer stream, a claim hotly contested, but even on iPlayer the episode is being attacked in the Daily Telegraph for being partly funded by WWF UK and the Royal Society for the Protection of Birds. The Daily Telegraph says these two establishment wildlife groups have a “campaigning agenda”.

When the message being put out by the world’s leading wildlife presenter is being constrained by one of the world’s leading information organisations (an organisation that proudly claims to be independent) for fear of a conservative backlash, then we have a classic ‘don’t look up’ moment.

Don’t look up

Don’t look up’ was the title and central idea of an American apocalyptic political satire film that came out in 2021 in which scientists tried to warn the world of in impending asteroid strike. When there was an opportunity to do something about it, the world ignored the warning as ‘doing something’ would shift the status quo. When it became apparent the threat was real, because the asteroid was growing larger in the night sky, the elites still thought they could escape (together with their privilege) by rocketing to another planet. To keep the masses from realising what was going on, they promoted the slogan ‘Don’t look up’.

The movie was a parable on climate change, and the unwillingness of society to respond to the warnings being put out by scientists because changing the status quo comes with short terms costs that the rich and the powerful don’t want to take on (costs of giving up some of that wealth and losing some of the power).

‘Don’t look up’ became a catch cry for climate denialism, and it had some resonance when it first aired.

But how quickly we forget. The movie came out in the dark days of the covid pandemic, a time before vaccines became available and lockdowns were rigorously enforced (and in some quarters vehemently rejected). Now, with the lifting of restrictions, everyone wants their cake and they want to eat it double fast. There’s even a term for it – revenge tourism – in which everyone is traveling as a way of making up for lost time during the pandemic. Though it might be asked, who are we taking revenge on? Planet Earth? Transport-related greenhouse gas emissions from tourism have been estimated at 5% of all human originated emissions.

So maybe none of us want to ‘look up’ for fear of upsetting our own plans of ever greater consumption and economic growth.

Don’t speak up

David Attenborough has been doing nature docos since Moses was a boy. He’s does a great job, but while he often points out issues of environmental decline, for most of his series he tries to stay as neutral and apolitical as possible. It’s something he’s often criticised for in environmental circles.

In recent years, however, as he has grown older and climate change and environmental disruption has ramped up, his neutral stance has markedly shifted to one of pleas for action. In 2020 he even suggested the coming decade was a make-or-break time for humanity.

And, as with all scientists who get proactive on climate change, he’s finding you face a backlash when you raise your head above the parapet.

Stand up and tell society it needs to change and those that have benefitted from the societal status quo will draw a target on you. Corporate and political interests will apply leverage to groups they can influence, spread misinformation, foment anger. In Attenborough’s case, that means a showcase on environmental decline is closed down by the very organisation that prides itself on its independence (but at the cost of becoming overly sensitive to government sensitivities and attacks by other media organisations).

Attenborough is big enough and strong enough to stand his ground and weather such attacks, but early career researchers pay a heavy price for standing up and being counted.

When a system becomes moribund

So what’s this ‘K’ phase business I opened with, and how does it apply here?

Society is complex system. Over time societies change following a variety of pathways; they develop and grow, weather change (or sometimes are overwhelmed by it), split into sub groups, collapse, reorganize and start again. Resilience scientists have described these patterns of change as adaptive cycles in which systems go through four phases of rapid growth, conservation (also known as the K phase), release and reorganisation. The rapid growth and conservation phases are times of relatively predictable dynamics and in which there is a slow accumulation of capital and potential through stability and conservation.

But this growth cannot continue indefinitely. As the system moves into the late conservation phase the system begins to become locked up as vested interests begin to dominate what can happen. Here are some things you might expect to see in the late K phase:
-Subsidies which were once designed to help set up new industries now prop up old industries (which are good at lobbying and influencing political power).
-More effort is put into protecting existing (sunk) investments rather than exploring new ones (think fossil fuels v renewals).
-Increased command-and-control (less and less flexibility).
-A pre-occupation with process (more and more rules, more time and effort devoted to sticking to procedures).
-Novelty being suppressed, with less support for experimentation (think of the government’s approach to research).
-Rising transaction costs in getting things done.
-Increases in ‘efficiency’ being achieved through the removal of apparent redundancies
(and ‘one-size-fits-all’ solutions are increasingly the order of the day).

Or, if you want another take on this, consider political economist Mancur Olson’s pathbreaking book, The Rise and Decline of Nations, published in 1982. He argued that a country’s economic stability ultimately leads to decline as it becomes increasingly dominated by organised interest groups, each seeking to advance their interests at the expense of others. It’s a very similar perspective to the complex systems framing.

So, next time you see something that appears to be a ‘don’t look up’ situation, ask yourself if this isn’t just another example of a complex system (eg, society) locking up because vested interests are seeking to perpetuate a status quo in which they benefit.

Maybe David Attenborough could do a doco on it.

A resilient world is built on humility

Featured

By David Salt

What helps keep a system resilient?

Of course, it depends on context, and everyone brings their own definitions to the party when answering this question. Which means you seldom find two people that will give you the same answer.

Yet, obviously, it’s a pretty important question.

Nine attributes

Towards the end of writing the book Resilience Thinking with Brian Walker, we asked many of the world’s most preeminent resilience scholars (including Buzz Holling) what they thought were the key lessons emerging from resilience science. They responded with a wide variety of answers, both in terms of length of response and areas covered. Even resilience experts vary in what they think is most important about the topic.

We didn’t have room in the book to reprint their responses so instead we attempted to distill their thoughts into a list of nine attributes of a resilient world. In summary, those attributes are:

1. Protect diversity: A resilient world promotes and sustains diversity in all forms (biological, landscape, social and economic).

2. Respect ecological variability: Resilience is about embracing and working with ecological variability, rather than attempting to control and reduce it.

3. Manage with modularity: Resilient systems consist of modular components. Failure in one component doesn’t collapse the system.

4. Acknowledge slow variables: There needs to be a focus on the controlling (often slowly changing) variables associated with thresholds.

5. Govern with appropriate feedbacks: A resilient world possesses tight feedbacks (but not too tight). Are the signals from cost/benefit feedbacks loosening?

6. Cultivate social capital: This is about promoting trust, well developed social networks and effective leadership.

7. Promote innovation: Resilience places an emphasis on learning, experimentation, locally developed rules and embracing change.

8. Govern with overlap: A resilient world would have institutions that include ‘redundancy’ in their governance structures, including a mix of common and private property with overlapping access rights.

9. Incorporate ecosystem services: A resilient world includes all the unpriced ecosystem services in development proposals and assessments.

It’s a good list (I’d even suggest a great list) though, of course, each attribute requires a lot of unpacking, explaining and illustration with examples (though, it did appear at the end of our book so readers who got this far were already in the frame).

But why only nine?

This was Brian’s idea: ‘Let’s set out nine attributes, one short of the biblical ten, and invite readers to suggest what attribute they would add to our list to complete it.’

I thought it was a dumb idea because a. I didn’t think we’d get much response (this was a science textbook after all), b. I suspected every reader would have their own idea (‘a resilient world would have lots of cats…’) and we’d just get a long list of pet thoughts with no emergent consistency; and c. what’s the point, how would we provide feedback to readers? This was a book afterall, not a monthly magazine.

The tenth (and 11th) attribute

As it turned out, I was wrong on all counts (hats off to you, Brian).

We received many hundreds of suggestions; most of them thoughtful, well considered and articulate.

And, while there was an enormous variety in the ideas being put forward (and no suggestion that cats would make for a more resilient world), there were clearly four themes constantly coming to the fore: democratization, fairness, learning and humility.

And, while we hadn’t planned on a follow-up book back when Resilience Thinking came out, it became apparent a few years later that people wanted more information on how resilience thinking can be implemented. Consequently, we wrote Resilience Practice, and included a discussion on the feedback we had received from readers of Resilience Thinking at the end.

Indeed, we added fairness and humility to our list of nine. Actually, we felt that the themes of democratization, fairness, learning and humility were all implicit to varying degrees in our original list of nine attributes. Our readers, however, obviously felt that equity and humility needed to be acknowledged explicitly; so we did. Here are the added two attributes to round off our list:

10. Enshrine fairness & equity: A (desirable) resilient world would acknowledge notions of equality among people, encourage democratization so that everyone has a say, a sense of agency, and promote the notion and practice of ‘fair trade’. These attributes would encourage diversity, innovation, collaboration and effective feedbacks while promoting higher levels of social capital.

11. Exercise humility: A resilient world would acknowledge our dependence on the ecosystems that support us, allow us to appreciate the limits of our mastery, accept we have much to learn, and ensure our people are well educated about resilience and our interconnection with the biosphere.

No panacea

Even if we adopted these 11 attributes as goals (even if we achieved them) there’s no guarantee that we will side step the looming shocks and changes currently facing our planet. However, a resilient world will be better placed come what may.

Which brings me to the end of this series of (relatively) ad hoc reflections on resilience thinking, what it is and why it’s worth knowing about. I’m not suggesting it will save the world; but I am certain it will provide new insights on the nature of the challenges facing us and why the complexity of the world makes these challenges so wicked. And, indeed, if we as a society are not prepared to acknowledge the complexity that lies at the heart of the challenge of sustainability, there is little hope of us meeting that challenge.

Resilience – the good, the bad and the ugly

Featured

By David Salt

Some 17 years ago a former boss of mine, Dr Brian Walker, approached me to write a book with him that made the science of resilience more understandable and engaging. That text, Resilience Thinking(Island Press, 2006), would become one of the first widely read, popular science books on the subject of ecological resilience. In my humble opinion, Resilience Thinking played an important role in bringing the ideas around resilience into the mainstream, raising the very notion of ‘resilience’ to the status of being a buzzword (with all the good and bad that comes with this).

At the time that Brian approached me I knew little about resilience science (and I was also ignorant about Brian being one of the world’s leading researchers in this field; I knew him as the ridiculously overworked Chief of CSIRO Wildlife and Ecology, where I had been his Communications Manager). When he asked me to co-author a book with him, a few years after this, I was a freelancer. Indeed, I was an ageing freelance science writer that was growing increasingly cynical about ‘science being the answer’ to the world’s growing sustainability challenge.

When Brian began explaining what resilience thinking was my first thought was ‘it’s just another bit of tricky science that will supposedly boost efficiency and save us all, while we dig the planet into an even deeper hole’, just like many of the other ‘breakthroughs’ I had covered and promoted over the years.

Well, I was quite wrong about this. By the time I had finished writing Resilience Thinking, I looked at the world anew. Things that had befuddled me in the past, now made sense. I looked at the world with different eyes and became a proselytiser for the cause. It really was an epiphany; so much so that I would go on to write a second book with Brian (Resilience Practice, Island Press 2012), numerous articles on the theme, and lecture on the topic.

Though, I should be careful using the world ‘proselytise’ because resilience thinking has been criticised by some as looking like a religion (it’s not, it’s an ever-developing science with all the peer review and validation that comes with that) with adherents that sometimes come across as acolytes (God, I hope I don’t sound like one). Because, for all the value and insight that comes with resilience thinking, it has collected some unfortunate baggage along the way. But let’s begin with the positives.

The good

When I finished writing Resilience Thinking I suddenly realised that while we used the word ‘resilience’, the book was actually a guidebook to ‘complexity’ (and complex adaptative systems). Though I had written about complexity in the past, this was the first time the concepts wrapped up under the cloak of complexity came together and made sense.

The world is a complex system operating at multiple linked scales. I am a complex system, so is my family, my region, my country; all these systems are linked in lesser or greater ways; all are constrained by their histories to some extent; will change over time (adaptive cycles); are capable of self-organisation in the face of disturbance and have the capacity to sustain their identities (resilience), but only up to a certain point (thresholds) beyond which they take on new ways of being.

When these insights are applied to the world around me, I realise, in a very fundamental way, that my big problem with the world is that I always expect that things (events, people, history) to be rational (that people always act rationally, for example) when in fact they are complex (and often irrational). Rationality is just our way of simplifying things, of dealing with the uncertainty that goes hand in hand with complexity. It’s a great approach in the short term but brings wretched results in the longer term as the complex systems around us self-organise around our efforts to optimise, simplify and hold things steady.

Attempting to explain ‘resilience thinking’ to others gave me a framework that explained for me why optimisation is such a flawed model (maybe ‘partial’ or ‘incomplete’ are better adjectives here) to move us towards ‘being sustainable’; why ‘efficiency’, while being important, is never the answer to long term sustainability; why ‘stability’ is a myth and attempts to hold things steady actually reduces a system’s resilience. These and many other epiphanies became clear as I applied the insights from resilience thinking to systems around me.

So, I would say that, for me, ‘resilience thinking’ is jam packed with inspiration and insight about the world around me. Possibly more important, however, I am aware of many readers of Resilience Thinking who came away with their own epiphanies about their own systems of interest.

When people begin considering the complexity of their own system(s) (looking for thresholds, seeing adaptive cycles, reflecting on where their sources of resilience might lie) they too begin to see the world in a different way, and are excited by the insights that pop up.

The bad

Unfortunately, descriptions of ‘complexity’ become very complicated all too quickly (though please don’t confuse these terms). It takes time (and some patience) to absorb ‘resilience thinking’. And, like complexity itself, resilience thinking is not a linear process in which you read ‘the formula’ press a button and the answer is delivered (‘the answer to your question on resilience is 43’).

Resilience thinking is more of a culture in which stakeholders in a system investigate their system, assess different facets of its resilience (where are the thresholds, what is its space of safe operation; where does it sit in the adaptative cycle, what are the system’s levels of adaptability and transformability, and so on), decide on a course of action, monitor and adapt around that decision; and then iteratively go through that process (compile, assess, act) again and again; learning, adapting, experimenting and transforming as you go.

That’s all good and well, and it’s what we should all be doing all the time, but managers, decision makers and policy people need simpler and linear processes to inform their actions and decisions. Resilience thinking is sometimes seen as ‘nice (if time and resources are unlimited) but unhelpful (in the real world)’ when it comes to getting on with things.

Also, many of the insights emerging from the application of resilience thinking are quite dependent on a particular context and may not hold in a different context. On top of this (and maybe because of this), one person’s insights often vary from the insights another person finds when applying resilience thinking.

Some people have accused resilience thinking of being somewhat vague. Others have even suggested that this is deliberate and even important when it comes to framing complexity. One philosopher asked: “Does resilience exhibit conceptual vagueness, and, if so, is that beneficial? Can looseness in concepts and meanings lend itself to shedding light on unsolved problems? While resilience research has established that redundancy is an asset for complex adaptive systems, does a similar finding also hold for conceptual frameworks?”

All of which is to say is that while resilience thinking can be inspirational, it can also be problematic in its implementation.

And the ugly

While acknowledging this, I do believe it’s an important first step in re-evaluating our failing approach to sustainability (an approach largely based on simplistic linear thinking, technology and efficiency).

I’m happy to acknowledge the good with the bad. Where I get extremely frustrated, however, is where political leaders and corporate spin masters see ‘resilience’ as an opportunity to claim action while actually doing nothing (or continuing with their environmentally damaging activity).

Our last national conservative government claimed they were building a ‘resilient’ Great Barrier Reef while subsidising and expanding the country’s fossil fuel sector. (Our new national government appears to be doing much the same.) Carbon emissions are killing our Reef.

In a similar vein, one of Australia’s biggest companies, BHP, co-funded the Australian Coral Reef Resilience initiative to protect the ‘resilience’ of the reef while continuing to expand their fossil fuel pollution.

When climate-charged wildfires tore apart coastal communities along New South Wales (NSW) coastline in 2019/20 (our Black Summer), the NSW Government created a new overarching recovery agency called Resilience NSW (because who can have enough resilience, and the NSW government is there to provide it). Two years later and instead of fires, unprecedented floods devasted NSW coastal communities. A government enquiry found that Resilience NSW (an agency that hadn’t even found its feet) had failed and should be abolished.

These are just a few local examples where the ideas of resilience are inappropriately used (and abused). This happens everywhere. The problem here is that resilience is complex, most people don’t have the opportunity to have a deep engagement with it, and politicians are quick to exploit that ignorance; in the first place to hide behind it, in the next to use it as the scapegoat.

In a rational linear world, they wouldn’t get away with this. But, of course, we don’t live in a rational world, do we?

To be or not to be? It’s really a question about whether we adapt or transform

Featured

By David Salt

To my mind, the word ‘transform’ is one of the most over used and abused words in the realm of sustainability scholarship and policy. It’s up there with the terms ‘resilience’ and ‘sustainability’, all of which have been rolled out so many times for so many mixed purposes that they have become panchrestrons (a fancy way of saying ‘buzz word’; a panchreston is an explanation that is used in so many different cases that it becomes almost meaningless).

The word itself seems harmless; ‘transform’ simply means to change into something else. In common parlance, however, it’s rolled out whenever someone wants to emphasise that the change we need has to be BIG! We’re not talking minor refinement or incremental reform here, we’re talking TRANSFORMATION! And this is problematic for several reasons. Consider this example.

Transformative change

In 2019, following the most comprehensive assessment of its kind, IPBES (the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) announced 1,000,000 species have been identified as threatened with extinction and that the rate of species extinction is accelerating. What do you do in the face of such alarming news? IPBES called for ‘transformative change’; and by that they meant a “fundamental, system-wide reorganization across technological, economic and social factors, including paradigms, goals and values.”

At the time I was sceptical anyone would listen because while no-one liked seeing biodiversity collapse, no government was going to introduce the wholesale changes being demanded. “The American way of life is not up for negotiation,” said President George Bush (Snr) at the 1992 Earth Summit in Rio, in a breathtakingly insular and cynical remark that all national leaders parrot in their own way.

This particular IPBES announcement in 2019 followed on decades of similar assessments saying much the same kind of thing (something I discussed here). Each time one of these biodiversity reports came out they were heralded with catchy, headline-seeking stats (‘a million species on the chopping block’), dire warnings (‘we’re heading for the abyss’) and demands for a new and even more ambitious set of policy targets (‘this time we must respond with BIG change’).

However, the IPBES announcement explicitly called for ‘transformation’ and even listed what that meant: “fundamental, system-wide reorganization across technological, economic and social factors, including paradigms, goals and values.” Now, I actually agree with everything IPBES is saying, but I disagree with the manner in which it was communicated. In some ways it’s pushing hyperbole to a new level, ‘the stakes are existential and the only solution is changing everything’. Predictably, the report got lots of media and disappeared without a trace. And biodiversity collapse continues at an accelerating pace.

What are we actually calling for?

Transformation IS big and very challenging. Be careful invoking it if you haven’t got a pathway for how it might be achieved because simply demanding it to happen can be less than useful.

Why is it so challenging? I think the school of resilience thinking has some useful ideas here. Indeed, the ideas of ‘transformation’ and ‘adaptation’ are central concepts in a resilience framing of the world.

The system you are interested in – be it a farm, a region, a forest or some other ecosystem – has its own identity (emerging from its structure, function and feedbacks). This system can absorb disturbance, self-organise, and still continue to sustain its identity up to a point. Push the system beyond this point, this threshold, and system loses its identity, it becomes something else.

Adaptation is about managing your system so that it holds onto its identity. It’s about stopping it from crossing a threshold or, if it does cross one, moving it back across to restore that identity (engineer a crossing to get back into a desired regime). It might even involve moving thresholds to create a larger ‘safe-operating space’.

Transformation is about creating a new and different system, to create a new way of making a living. An example comes from South Eastern Zimbabwe where, in the 1980s, ranchers transformed their cattle ranches to game hunting and safari parks when the livestock industry proved unviable.

Transformation is hard as the existing system has a lot of inertia and sunk investment. Fossil fuel companies have long resisted the growth of renewable energy; neoliberalism will defend itself to the death as will autocratic dictatorships. Or, if you want to look at a smaller scale, a farm or business or even a golf club, will take a lot of persuading to transform their enterprise into something quite different because their identity is central to their very existence (and each system has made long-term investments in staying as they are).

Transformative capacity

For transformation to occur, resilience thinking says there are three important factors needed. The first is to get beyond denial. The ‘rule of holes’ is to stop digging when you realise you’re trapped in one. If your farm, business, golf club or energy sector is not sustainable in a changing climate-ravaged world then you need to acknowledge it and accept your existing ‘identity’ might have to transform.

However, even if you accept the need for transformation, what are you going to ‘transform’ to? The second factor is the ability to explore options for transformation. A resilient society is one that encourages experimentation in order to explore options.

And, if an experiment works (if, for example, the golf club works better as a multi-function community centre producing food), the third factor needed for transformation is a capacity to upscale the successful experiment so it becomes the norm everywhere.

These three factors add up to transformative capacity, and each presents major challenges for the managers of the system. Which is why calls for transformation are often made but rarely result in anything happening at all; it’s just too difficult.

To be or not to be…

What happens instead is resistance and denial (think of 50 years of climate wars), and token efforts at adaptation (think announcements of the latest techno gadget that will improve efficiency by X%). Because, at the end of the day, no national leader is going to suggest that the identity of their country (or the many electorally important sectors that have traditionally been the strength of that country) should be transformed into something else. What they will say, instead, is that by making the existing system work better (grow faster, be more efficient, etc) we can solve the mounting challenges that confront us (thereby breaking the ‘first rule of holes’).

So, when IPBES called for ‘transformative change’ to meet the challenge of collapsing biodiversity, I say ‘good luck to them’. However, without an honest engagement with what it is they are proposing when they invoke ‘transformation’, a systems approach, I can’t see anything changing (and so far I’m right).

Adapt or transform is a pretty big choice*, it’s as fundamental as the Hamlet’s reflection with ‘to be or not to be’; because it’s all about the essence of the system we care about, its identity.

* Should you adapt or transform? Actually, it’s not a binary choice. On the surface, it may appear there’s a tension between adapting and transforming. But the tension is resolved when you consider the system at multiple scales, because making the system resilient at a regional scale, for example, may require transformational changes at lower scales. Adapting and transforming are actually complementary processes, and adaptability and transformability are complementary attributes of a resilient system.

Losing it – the consequences of stepping over the threshold

Featured

By David Salt

In Australia, we called the horrible summer of 2019/20 the Black Summer. Unprecedented heat waves and drought led to the biggest, most ferocious, most extensive wildfires this nation had ever known.

I wonder what the world will call 2022? Once again that word ‘unprecedented’ gets rolled out to describe a series of heatwaves, extreme storms, massive floods and record-breaking droughts. This year these events were happening all over the world (and especially across Europe, Asia and America during the northern hemisphere summer). Will it be the ‘Angry Summer’ or the ‘Season of our Great Discontent’ or maybe just the year of ‘Climate Breakdown’. (At what point do we know it’s broken?)

Or maybe the climate disruption will just continue and even grow worse, as many climate scientists are predicting, and 2022 will be wilfully forgotten as we struggle to deal with each new emerging weather crisis.

The idea of normal

When describing abnormal events, unprecedented episodes or historic happenings, you need to have some idea about what ‘normal’ actually means. In some cases this is relatively straightforward.

We have temperature records, for example, that go back for at least a century so it’s easy to define ‘normal’ with statistical precision. Our temperature has ranged between X and Y, and there is a different average max and minimum value for each month of the year. This August was particularly hot for many regions in the northern hemisphere, so when you hear on the news that temperatures broke records, or were above average, you can appreciate just what is meant.

The more variables you bring in (precipitation, wind speed, humidity, wild storms etc), the harder it is to characterise what is normal. Of course, these variables are what add up to weather, and long-term average weather is what we call climate.

If the weather gets ugly, we normally console ourselves that we just need to survive this rough patch and at some point the weather will ‘return to normal’ – the rains will replenish the dams after the drought or calm will follow the big storm.

‘Return to normal’ is a form of equilibrium thinking. Your world gets rocked by some disturbance, your equilibrium is thrown out, but you do everything you can to bounce back, to return to normal.

Of course, I’m talking about the notion of resilience – the capacity to cope with disturbance and bounce back (the word ‘resilience’ derives from the Latin ‘resilire’, meaning ‘to jump back’ or ‘to recoil’).

What’s normal for a complex system

‘Resilience thinking’ is all about how this idea of ‘recovery’ applies to complex adaptive systems. Complex systems have the capacity to self-organise. Resilience is the amount of disturbance a system can absorb and still retain its identity, still continue to function in much the same kind of way.

In recent blogs I’ve attempted explain what complexity means, and how complex systems change over time, how they go through a pattern known as an adaptive cycle. The concept of adaptive cycles is one important building block of resilience thinking, the other is the idea of ‘thresholds’.

There are limits to how much a complex system can be changed and still recover. Beyond those limits the system functions differently because some critical feedback process has changed. These limits are known as thresholds.

When a complex system crosses a threshold it is said to have crossed into another ‘regime’ of the system (also called a ‘stability domain’ or ‘basin of attraction’). It now behaves in a different way – it has a different identity (or you might say it has lost its original identity).

In coral reefs there’s a threshold on the variable of the level of nutrients in the surrounding water. If nutrients become too high, the coral will be displaced by algae. The coral reef identity is lost, replaced by the identity of an algal reef.

On many rangelands there is a threshold on the amount of grass present. If the grass level falls below a certain level (because of too many grazing animals or a prolonged drought), shrubs begin to take over. The grassy rangeland identity is lost, replaced by a shrubland.

Sometimes it’s easy to cross back over to the identity you want, sometimes it’s difficult and sometimes it’s impossible.

Tipping points

In a recent blog I discussed how fossil fuel corporations are complex systems. The identity of this system is heavily influenced by quarterly profit statements; more so than any concern they might hold for longer term climate disruption. The levels of the profits in those quarterly statements likely has a threshold point, below which the fossil fuel corporation will likely change its business (eg, take on the identity of a renewables company, maybe) or shut down. Either way, crossing this threshold leads to a change of identity in this system. (Of course, what might put downward pressure on their profits is stronger government regulation or broader community rejection of the cost being imposed on society by the fossil fuel company.)

In my last blog I also said you could view the British Monarchy as being a complex system. Its identity hinges on public acceptance and support over time, something the late Queen Elizabeth II understood and worked with like a pro. Again, its likely a threshold point exists on this variable of public support, below which the Monarchy becomes vulnerable. QEII represented integrity, authenticity, stability and certainty. She had very high levels of social approval (social capital) that has ensured that the system of the Monarchy had resilience, even to the disturbance of her own death, and the Crown passed seamlessly to her son, now King Charles III. But imagine what might have happened if the Queen didn’t have that level of social capital. Or what happens if King Charles squanders that social capital? Smooth successions aren’t always the rule in the UK (or elsewhere), and many countries don’t need Queens (or Kings) to function.

Thresholds occur in many complex systems however they are often described as ‘tipping points’ where they occur in the social domain. In addition to the two examples I just discussed (profit levels and levels of public approval), tipping points might manifest as changes in fashion, voting patterns, riot behaviour, or markets.

Defining a safe operating space

So here is useful way of defining a system. Every system can be described in a variety of ways using a number of variables. The identity of the system can be characterised by an average range of those values. While kept in that range, the system will behave as you expect, be it a business, a monarchy, a coral reef or a rangeland. However, when the system passes a certain level on one of a number of key variables (eg, profit, popularity, nutrients, grass cover) – a threshold or tipping point – the system changes its identity and begins to behave differently (often in strange or undesirable ways).

Or, in other words, you can understand a system’s identity by knowing how much change it can take before that identity is lost, replaced by a different identity.

Not only are thresholds critical to understanding the behaviour of complex systems, they are the basic limits to whatever enterprise you’re responsible for or have an interest in. To use the phrase in a prominent analysis of global-scale thresholds (Rockstrom et al 2009), thresholds define the safe operating space of your system.

And how are we going in keeping our society in a safe operating space? Well, considering our experiences with the Black Summer of 2019 or the Angry Summer of 2022, not so well.

Climate and weather systems are complex systems too. Their current behaviour suggests they have been pushed over critical thresholds and their emerging identity is something quite new, quite destructive and terrible. Allowing the Earth system to cross these thresholds comes with an enormous cost to society, and will sorely test our own resilience as we cruise into an increasingly uncertain future.

It’s not just the intensity of a specific event (a single hurricane for example) that’s important, it’s also the frequency of such disturbances. The Great Barrier Reef can survive mass bleaching events if they only occur once every 20 years but it loses its ‘identity’ if they occur every few years (which is now what’s happening).

Death of the Queen, identity and a sustainable world

Featured

By David Salt

The Queen is dead, long live the King. Okay, we’ve said it, can we now please return to normal transmission*!

On the announcement of the death of Queen Elizabeth the 2nd, Australia sunk into a blackhole of mourning (described by some in the twitterverse as ‘mourn porn’). All news bulletins and national programming seemed only to talk about her passing, how good she’d been, and the 1,000 tiny (tedious) steps of what happens now as her son becomes King. We suspended parliamentary business for a staggering 15 days and declared a public holiday that, because of its suddenness, some believe may cost our economy over a billion dollars. All of this in a country on the other side of the planet from where she had lived, with a population whose majority want us to ditch the monarchy completely, and whose government for all intents and purposes is independently elected and run. What gives?

Of course, there are hundreds of stories currently doing the rounds at the moment on how wonderful and enduring Queen Elizabeth had been. However, for my money, the furore over her passing is more about what it means for our own identity – what and who we are.

The Queen has been our monarch for over 70 years. She’s always been there performing her many public duties through thick and thin; with a polished reserve, constancy and perseverance that is almost superhuman. She is universally lauded as a trusted and hard-working soul, a role model of public service, temperance and restraint. Her very existence gave us confidence in the stability and validity of the system of which we are a part, a confidence that this system would endure and be around to sustain ourselves and our children.

So, even though the Queen was growing old, her death still hit us like an existential slap. Yes, she was a good person, but suddenly her constant presence had vanished, and we all needed reassurance that the validity and dependability of our system was still there, that we still had good reason to believe in the certainty of tomorrow.

The Queen and the Great Acceleration

So much has happened during the 70 years of her queenship. If you think about it, her reign began in 1952, just as the ‘Great Acceleration’ of humanity was taking off; a time of unprecedented technological change, economic growth, exploding population and accelerating consumption. Beginning in the 1950s, humanity built more dams, converted more land to agriculture, eliminated more species and released more greenhouse gases than at any other time in history.

By the 1970s scientists were beginning to point out how unsustainable this development was, but the warnings did little to change our course over the next half century.

With the new millennium, the warnings started proving true. The ‘spotfires’ of deep droughts, floods and mass coral bleachings are becoming more intense and frequent. 2022 seems to have seen most of the northern hemisphere engulfed in one climate-ramped natural disaster after another. The US is burning, Pakistan is drowning while all our great rivers are withering. A climate crisis is emerging.

And, during this time, our trust in the institutional pillars of society have been eroded by neoliberal drivers and market forces. A recent Australian Prime Minister** observed: “We face the spectre of a transactional world, devoid of principle, accountability and transparency.”

‘False news’ and misinformation cloud all our reflection, as tribal partisanship displaces reasoned debate and good governance.

Throughout all this tumultuous, transformational change, the Queen was always there, always constant. The monarchy no longer had the power and influence of earlier centuries, but the Queen still represented all the symbols (flag, crown and anthem) that lay under everything we have built (and fought for, and in some cases died for).

For King, country and the higher cause

Part of that is what the empire built lies here on the other side of the planet. Almost 250 years ago, Britain deported felons to a remote settlement in New South Wales, and that convict colony grew and flowered to become a vibrant multi-cultural, economic powerhouse that we now call Australia.

For King/Queen, God and flag, we displaced (and oppressed) a pre-existing First Nations culture as if it had never existed (a process codified as Terra nullius). Indeed, Indigenous people were not given recognition in the Australian Constitution till the 1960s, and (against a backdrop of multiple appalling legacies in the areas of health, education and welfare) we’re still fighting over how their voice might be heard in our national parliament.

Australia leads the world when it comes to extinction rates, land degradation and per capita emissions of greenhouse gases. Until very recently, we have been seen as the climate change laggards of the developed world.

The belief in ‘Queen and country’ have been central to our society and how we have justified so much of our development trajectory; ‘yes there have been costs, people and cultures have suffered, but it’s all been done for a higher cause’.

The loss of ‘our Queen’

So, with the sad loss of ‘our Queen’, our very identity has been under siege as we reflect upon what it is we have built, and how much certainty is there that it will be there in the future.

The fact that the Queen was undeniably an honest, hardworking servant of the public only clouds our reflections. She was a ‘good’ person but what is the value of the institution she represents, and is this belief in the Crown really an appropriate justification for how we are developing this world?

I quipped at the beginning: ‘can we please get beyond this and let normal transmission return’. But on reflection, humanity can’t afford ‘normal transmission’. We’re driving off a cliff at the moment and the powers that be are only concerned with the condition of the car they’re driving, not where it’s going.

Actually, what we should be saying is: The Queen is dead, long live the King, and may we use this moment of fragility and uncertainty to honestly reflect on the world we have built in their names.

*Speaking of ‘normal transmission’, my recent blogs on Sustainability Bites have been reflections on resilience thinking. This blog on the Queen has been a bit of a divergence. And yet, thinking of the Monarchy as a complex adaptive system might reveal some interesting insights. For example, how much disturbance (and of what form) can the Monarchy absorb before it loses its identity, and begins to operate as a different system (ie, how resilient is this system)? And does the Monarchy have its own adaptive cycle? And during what periods might reform actually take root?

** Which recent Australian Prime Minister observed: “We face the spectre of a transactional world, devoid of principle, accountability and transparency?” I think this is a smart and incisive observation, so I am totally gobsmacked that it was uttered by PM Scott Morrison, the most unprincipled, unaccountable and secretive Australian Prime Minister in living memory.

On identity, complexity and a ‘little’ fossil fuel project off the West Australian coast

Featured

By David Salt

Earlier this month I spotted a tweet that chilled my soul while neatly summing up the challenge of sustainability for our age.

Here it is:

In a nutshell it shows the CEO of a major fossil fuel company extolling the virtues of a massive new project, the Scarborough development, with a comment from one of the world’s top coral scientists describing it as ‘a crime against humanity’ (while asking the responsible politicians to respond appropriately).

One single development

We’ve discussed aspects of the Scarborough development (the biggest oil and gas development to be built in Australia in a decade, situated off the coast of Western Australia) a few times on Sustainability Bites (see Lies, damned lies and environmental economics). It’s worth repeating that an analysis by the company Climate Analytics found that the total emissions from the proposed Scarborough project will be just under 1.4 billion tonnes, three times Australia’s annual emissions! Think about that. Climate Analytics is under no illusion and points out this single project undermines the Paris Agreement (of which Australia is a signatory).

The Australian Conservation Foundation has calculated these emissions will result in 0.000394 degrees of additional global warming that will, among other things, accelerate the decline of the Great Barrier Reef (which may partly account for the coral scientist’s dismay at Woodside’s promotional tweet).

Is an extra 4 x 10,000ths of a degree significant? Keep in mind this is a single development which, by itself, has the capacity to create a measurable global temperature increase at a time when the world is already overheating. This summer has seen unprecedented droughts, storms, fires and floods across Asia, Europe and North America. At this time no-one has even attempted to calculate the economic impact of the carnage from this northern summer, let alone tally the lives lost. And this situation only promises to get worse as carbon emissions increase.

A boon for the economy

Despite the accelerating impacts from climate change being felt all around the world, Woodside’s CEO tells us (though more likely she’s really wanting her shareholders and politicians to hear this) that Scarborough will “deliver value for Woodside shareholders and significant long-term benefits locally and nationally, including thousands of jobs, taxation revenue and supply of gas to export and domestic markets for decades to come.”

I cynical paraphrase might read: “let this project proceed and shareholders will be richly rewarded by quarterly rises in share price; while the enabling government can claim ‘jobs, jobs, jobs’, regional development and a secure supply of energy well into the future (and definitely beyond your next election).”

The planet? Well, it may endure a little more heating but focus on the profits.

And humanity? Bits of it will do very nicely, thank you very much, from the increased economic activity. And those that don’t? Well, most of them don’t vote in Australia and they definitely aren’t shareholders in Woodside, so there’s nothing to worry about here.

In any event, the planet and humanity are not the focus of the CEO’s missive to the masses; she’s more worried about quarterly returns to shareholders.

The standard model

The standard explanation for this situation goes something like this: some people put the economy before all else and believe the ‘climate alarmists’ are overstating the problem. These people might even acknowledge the climate is becoming increasingly problematic but are confident that as the crisis grows we’ll make more of an effort to fix it, and science and technology will save us. These people think that radical action to reduce carbon emissions will cause deep and unjustifiable pain to the economy and everyone’s standard of living.

The other side (which includes most scientists) believe humanity is changing the Earth System in deep and unpleasant ways that will hurt everyone. We need to do something now. Enabling new fossil fuel developments is mad; some describe them as ‘crimes again humanity’.

Both sides think the other side is crazy, and many have stopped listening to anything coming out of the other side.

You might have your own variant on this ‘standard model’ of the sustainability challenge but I believe most people subscribe to some version of it: two sides/tribes, two sets of values/priorities, situation gets worse, both sides blame the other and after a while everyone stops listening to anyone outside of their own tribe. It’s simple and neat – my side right, your side wrong.

A more complex model

Now here’s a more nuanced explanation that uses a bit of complexity (resilience) theory. Each of the players/actors/groups in this situation are complex systems, and each has its own identity emerging from the structure, function and feedbacks that make up that system. Understanding the feedbacks is important to understanding the behaviours of these systems.

The politicians are very responsive to voter’s needs and the level of support received from party supporters (including lobbyists and political donations).

The fossil fuel companies are very responsive to changes to the quarterly returns on investment and shareholder sentiment.

The scientists are very responsive to changes in biophysical indicators of the many components that make up the Earth System, the respect of their peers and the papers they can publish.

And the voters just want to be able to pay their bills, have a little certainty in what tomorrow brings, and maybe have the occasional holiday.

These are interacting complex systems and expecting them to behave in simple rational ways doesn’t necessarily help us resolve the differences that emerge between them over time.

Pointing out that the other side is wrong may work well with your own tribe but it usually does nothing to change the behaviour of the other side.

However, understanding what’s central to the identity of the other side and working on the feedbacks that shore up that identity is much more likely to produce change.

If voters don’t believe the future is safe, if shareholders no longer trust their shares will yield dividends in the longer term, if politicians are only allowed to make fully accountable and transparent decisions, then the very identity of their systems change, as does its behaviour. Of course, changing these feedbacks is never easy.

Another thing about complex systems

Another thing about complex systems that’s very relevant to this discussion. They are non-linear. That means you can’t always predict how they’ll change based on how they have changed in the past. Sometimes big disturbances can hit your system and yet it can absorb them and its identity remains intact (the system is ‘resilient’). Other times, it will only take a small disturbance and the system’s identity collapses (unexpectedly and often quickly, does anyone remember the Soviet Empire?).

The Earth System itself is a good example of this non-linearity. The group of scientists who first proposed the idea of ‘planetary boundaries’ (Rockstrom et al, 2009) pointed out that the Earth System itself is a complex system that has considerable capacity to absorb disturbances (changing atmospheric concentrations, declining biodiversity etc) and still retain its identity. For the past 10,000 years, that identity has been one of a relatively stable climate that has enabled the rise of civilisation.

But this capacity to continually absorb disturbance has limits, sometimes referred to as thresholds. They proposed a set of planetary boundaries (possible thresholds) beyond which the stability of the Earth System could well be lost. They proposed nine planetary boundaries, most of which we have now transgressed.

In some ways, the scientists suggest, the complexity of the Earth System has lulled us into a false sense of security. All the change we’ve imposed on it (most of it in the last half century), has been absorbed by the Earth System and it continues to function in a way conducive for humanity. But, having crossed these planetary boundaries, we have exhausted the planet’s capacity to absorb further disturbance. Many now believe further incremental disturbance may change things drastically. Indeed, we may even be seeing this with the savage summer of 2022.

Which all serves to underscore how complex the challenge of sustainability can be. We are all complex units operating in complex groups within a complex Earth System. ‘Simply’ pointing out why the opposite side is wrong may score points with our side but does little to fix the problem. For that to happen we need a deeper engagement with the complexity in which we find ourselves, more reflection on what gives us (our tribe and our planet) our identity, and a greater respect for the things that impact on that identity.

Banner image: Civilisation rose during an epoch of climate stability. Now that stability is possibly breaking down. So far, our response to this possibility has been simplistic and ineffective. Maybe it’s time to acknowledge the problem is complex. (Image by Reimund Bertrams from Pixabay)

The perils of command and control and the pathology of Natural Resource Management

Featured

By David Salt

As a younger man I honestly believed that sustainability was a tractable problem; a difficult challenge no doubt but one that was solvable with hard work coupled with science and technology. And, as a confident young thing, I thought I could contribute to this outcome by serving in the area of science communication and education; get more talented young people into science, and increase community acceptance of emerging technological solutions so they can be effectively implemented.

How might science and technology save us? By providing us with insights on the many problems being faced by humanity and the environment, and by helping humanity lighten its footprint on Planet Earth. Well, science has definitely provided ample insights on the plight of our planet, and technology has given us so many ways to be more efficient in how we do things.

For all that, however, we are moving away from being sustainable; indeed, we seem to be accelerating away from it. In the last half century, humanity has pushed the Earth system over several planetary boundaries, unleashed a sixth extinction event, and seems unable as a global community to do anything about greenhouse gas emissions which are remorselessly on the increase (as a by-product of our addiction to economic growth).

Science and technology has underpinned so much of our wealth creation and economic activity, and many techno-boosters are fervent in their belief that science and technology is the solution to the many problems facing our environment (indeed, I heard Australia’s Chief Scientist say this exact thing on the radio this morning, as I write.)

As I grew older and watched the natural world decline around me (on a number of scales; think of weed infestation in your local bush reserve, glacial retreat or the bleaching of the Great Barrier Reef), my enthusiasm for (and faith in) science and technology also declined. I could see the potential of all these new discoveries (think renewable energy, nanotech and biotech as examples) but could never see where the outcomes were creating a more sustainable future. For example, for every 10% improvement in efficiency in process X, we seemed to see 100% increase in people using that process resulting in more waste, more consumption and more damage (albeit less impact per capita, see the Rebound Effect for a discussion on this).

The dangers of partial solutions

It’s not that I’m anti science and technology and I do believe increasing efficiency is important. However, by themselves they are not enough.

Then I was asked to write a couple of books on resilience science (Resilience Thinking and Resilience Practice) and my doubts on the belief that ‘science and technology is the solution’ crystallised into a new way of looking at the world. The experience of writing about resilience opened my eyes to ideas of complexity, and the capacity of a complex systems to absorb disturbance and retain their identity (the definition of resilience). The consequences of these ideas are deep and far reaching. In a range of different ways, I’ve been attempting to articulate them in my stories for Sustainability Bites.

One major consequence of acknowledging the complexity around us is to be aware of the cost of partial solutions sold to us as complete answers. Science and technology (and endlessly increasing efficiency) are not only not enough to move us to being sustainable, an exclusive reliance on them (and belief in them, think ‘technology not taxes’) will actually reduce resilience in the systems we depend upon and make us more vulnerable to disturbance.

There are many lines of evidence supporting this contention (see Resilience Thinking and Resilience Practice) but in the space I have here I’d like to discuss how natural resource management agencies decline over time. Improving science and technology (and efficiency) is often touted as the solution but only fuels this decline. This discussion is based on a landmark paper by CS Holling (one of the founding fathers of resilience thinking) and Gary Meffe, written a quarter of a century ago: Command and Control and the Pathology of Natural Resource Management.

The command-and-control pathology

Holling and Meffe point out that when command and control is applied in natural resource management, the initial phase is nearly always quite successful. Insect pests are reduced by pesticide use; fishing and hunting are enhanced by stocking or predator removal; forest fires are suppressed for years; floods are minimized by levees and dams.

But what follows on these initial successes is rarely acknowledged. The agencies responsible for management shift their attention from the original social or economic purpose towards increasing efficiency and a reduction in costs. (Of course, all agencies/companies do this over time not just NRN agencies. It’s a pattern well described in the idea of ‘adaptive cycles’ first proposed by Holling.)

NRM agencies search for better and more efficient ways to kill insects, eliminate wolves, rear hatchery fish, detect and extinguish fires, or control flows. Priorities thus shift from research and monitoring (why ‘waste’ money studying and monitoring apparent success?) to internal agency goals of cost efficiency and institutional survival.

Holling and Meffe contend that as this happens, there is a growing isolation of agency personnel from the systems being managed and insensitivity to public signals of concern. They describe this as institutional myopia and increased rigidity (again, something well described by the theory of adaptive cycles).

At the same time, economic activities exploiting the resource benefit from success (of more fish, or water or whatever) and expand in the short term. We see greater capital investment in activities such as agricultural production, pulp mills, suburban development, and fishing and hunting. There’s nothing wrong with this, they say, within limits.

But the result is increasing dependency on continued success in controlling nature while, unknown to most, nature itself is losing resilience and increasing the likelihood of unexpected events and eventual system failure. When natural systems are ‘controlled’ they invariably lose their natural diversity and processes, which leads to a declining ability to absorb disturbance (while maintaining its identity).

With dependency comes denial and demands by economic interests to keep and expand subsidies, and pressure for further command and control.

So, the initial successes of command and control come with a costs that are usually never acknowledged. Command and control reduces natural variation and erodes resilience, environmental managers aim for efficiency rather than connection with the system they are managing, and economic interests that benefit from original command and control distort the system to maintain it. The composite result is increasingly less resilient and more vulnerable ecosystems, more myopic and rigid institutions, and more dependent and selfish economic interests all attempting to maintain short-term success.

Holling and Meffe point out that solutions to this pathology cannot come from further command and control (for example, stronger regulations) but must come from innovative approaches involving incentives leading to more resilient ecosystems, more flexible agencies, more self-reliant industries, and a more knowledgeable citizenry.

Back in the ‘real world’, you’ll largely hear our political leaders deny the complexity of this and simply say science and technology will save us. Unfortunately, in a complex world, simple solutions have a habit of only making the situation worse.

Don’t get me wrong, I still love science and technology. However, by themselves, they are not the solution. To contribute to a sustainable world, they need to work with complexity, not subjugate it.

Banner image: Dams are an important piece of human infrastructure offering many valuable short-term benefits by controlling our rivers. In the longer term they come with a range of often unacknowledged costs. They reduce the natural variability of the river; they encourage human settlement in areas subject to flooding; and allow food production in areas that normally wouldn’t support agriculture. Over time, the agencies managing the dam become myopic and rigid, the economic sectors depending on the dam become increasingly reliant and selfish, and the river system becomes increasingly vulnerable to disturbances.

The myth of the optimal state: adaptive cycles and the birth of resilience thinking

Featured

By David Salt

Being sustainable, is tough. So far, we (as in humanity) are failing at the task miserably. My contention is that a big part of the problem is our inability to deal with the complexity of the systems around us, that we are a part of. Rather than acknowledging this complexity, we impose framings on these systems treating them as simple. (I discussed these ideas in complicated vs complex.)

Command and control

Simple systems can be managed and controlled, and held in an optimal state for as long as needed. Complex systems, on the other hand, self-organise around our efforts to control them. They can’t be held in an optimal state.

The notion of an ‘optimal sustainable yield’ was a widespread idea in natural resource management last century. The belief was that if you knew a little about what drives a natural resource (say reproductive capacity in fish stocks or forest trees), you could harvest that system removing an optimal amount of that resource forever as it would always replace itself. It’s a command-and-control approach that left countless collapsed fisheries and degraded landscapes in its wake.

‘Command and control’ involves controlling aspects of a system to derive an optimized return. The belief is that it’s possible to hold a system in a ‘sustainable optimal state’.

However, it’s not how the world actually works. Yes, we can regulate portions of the system, and in so doing increase the return from that portion over a short time frame, but we can’t do this in isolation of the rest of the system. If we hold some part of the system constant, the system adapts around our changes, and frequently loses resilience in the process (ie, loses the capacity to recover from a disturbance).

While we can hold parts of the system in a certain condition, the broader system is beyond our command. Indeed, no one is in control; this is a key aspect of complex adaptive systems.

Resilience thinking is an alternate approach to working with these systems, an approach that places their complexity front and centre. And the origins of this approach are entwined with an early realisation that a command-and-control approach to harvesting natural systems will always strike problems eventually. (The following example is based on a discussion that appears in the book Resilience Thinking.)

Of budworms and social-ecological systems

Spruce fir forests grow across large areas of North America, from Manitoba to Nova Scotia and into northern New England. They are the base of a highly valuable forestry industry.

Among the forests’ many inhabitants is the spruce budworm, a moth whose larvae eat the new green needles on coniferous trees. Every 40 to 120 years, populations of spruce budworm explode, killing off up to 80% of the spruce firs.

Following World War II, a campaign to control spruce budworm became one of the first huge efforts to regulate a natural resource using pesticide spraying (thanks in part to new technologies emerging from the war).

Initially, the pest control proved a very effective strategy, but like so many efforts in natural resource management that are based on optimizing production, it soon ran into problems.

In a young forest, leaf/needle density is low, and though budworms are eating leaves and growing in numbers, their predators (birds and other insects) are easily able to find them and keep them in check. As the forest matures and leaf density increases the budworms are harder to find and the predators’ search efficiency drops until it eventually passes a threshold where the budworms break free of predator control, and an outbreak occurs.

While the moderate spraying regime avoided outbreaks of budworms, it allowed the whole forest (as distinct from individual patches) to mature until all of it was in an outbreak mode. Outbreaks over a much greater area were only held in check by constant spraying (which was both expensive and spread the problem).

The early success of this approach increased the industry’s dependence on the spraying program, intensified logging and spawned the growth of more pulp mills.

Now there was a critical mass of tree foliage and budworms. The whole system was primed for a catastrophic explosion in pest numbers. The managers in this system were becoming locked into using ever increasing amounts of pesticide because the industry wouldn’t be able to cope with the shock of a massive pest outbreak. The industry had little resilience, and yet the continued use of chemicals was only making the problem worse. They had created a resource-management pathology.

Adaptive cycles

The industry acknowledged the looming crisis and engaged ecologists (including CS ‘Buzz’ Holling) to see how they might tackle the problem from a systems perspective. In 1973, Holling proposed a new analysis of the dynamics of the fir forests, one based on what he described as ‘adaptive cycles’.

Forest regions exist as a patchwork of various stages of development. The cycle for any one patch begins in the rapid growth phase, when the forest is young. The patch then proceeds through to maturity, and eventually, following some 40 to 120 years of stable and predictable growth (referred to as the ‘conservation phase’), the cycle tips into the release phase. The larvae outstrip the ability of the birds to control them, larvae numbers explode, and the majority of forest trees in that patch are killed. Their rapid demise opens up new opportunities for plants to grow, and during the reorganization phase the forest ecosystem begins to re-establish itself. The cycle then repeats.

With this understanding of the cycle and the key changing variables that drive the system, the forest managers were able to fundamentally modify the manner of their pest control. Rather than continually using low doses of pesticide over wide areas they switched to larger doses applied less frequently at strategic times over smaller areas. They re-established a patchy pattern of forest areas in various stages of growth and development rather than keeping wide areas of forest primed for a pest outbreak.

The forest industry also changed through the process, moving to regional leadership with a greater awareness of the ecological cycles that underpinned the forest’s productivity.

From budworms to resilience thinking

The case study of the spruce budworm and the fir forest is important on many levels as it was in part the genesis of what has become resilience thinking. During his investigations, Holling proposed that the key to sustainability was an ecosystem’s capacity to recover after a disturbance, not the ability to hold it in a notional optimal state.

He also recognized that the ecosystem and the social system had to be viewed together rather than analyzed independently, and that both went through cycles of adaptation to their changing environments. Adaptive cycles don’t just happen in nature, they happen in communities, businesses and nations, it’s feature of complex adaptive systems.

His proposal catalyzed the thinking of ecologists and researchers (with an interest in systems) all over the world because similar patterns were being identified everywhere social-ecological systems were being studied.

One key insight that grew out of an understanding of adaptive cycles is that bringing about change/reform in a social-ecological system is always difficult. However, windows of opportunity do open when a system goes into a release phase, although the window doesn’t open for long. You need to be prepared to seize the opportunity while it’s there.

A basic lesson I draw from the notion of adaptive cycles is that systems get locked into themselves over time and become rigid. There’s no such thing as a sustainable optimal state because even if the system is managed into a condition deemed desirable, it then progressively loses its capacity to learn, innovate or keep its flexibility (often in the name of efficiency). Efficiency is important but is never the complete answer. Efficiency is not the key to sustainability.

Over the decades since Holling first described adaptive cycles, the models and the thinking associated with managing for resilience has gone through much refinement but the two core ideas remain at its heart: the fact that social-ecological systems constantly move through adaptive cycles over many linked scales, and that they can exist in different stable states. I’ll discuss this second building block in my next blog.

Thinking resilience – navigating a complex world

Featured

By David Salt

Our world seems to be coming unstuck at the moment. Climate fuelled weather extremes – floods, droughts, heatwaves and fires – are crippling large parts of humanity. Many people are grappling for answers; What do we do? Why haven’t we already done something about this? It’s not like we haven’t been warned (repeatedly and with comprehensive detail by our climate scientists and others).

I believe many of your problems lie in our inability to deal with the complexity of the world around us (my last two blogs discussed this very thing – we can’t fix this because it’s complex and complicated vs complex). One way of better appreciating that complexity and navigating a way through lies in the area of resilience thinking.

The word ‘resilience’

The word ‘resilience’ is now common in many vision and mission statements. But ask the people who use these statements what they think it means and you get a range of different answers, most of which relate to how something or someone copes with a shock or a disturbance.

Concepts of resilience are used in all sorts of disciplines, but it has four main origins – psycho-social, ecological, disaster relief (and military), and engineering.

Psychologists have long recognised marked differences in the resilience of individuals confronted with traumatic and disastrous circumstances. Considerable research has gone into trying to understand how individuals and societies can gain and lose resilience.

Ecologists have tended to describe resilience in two ways; one focused on the speed of return following a disturbance, the other focused on whether or not the ‘system’ can recover. People engaging with resilience from the perspective of disaster relief or in a military arena incorporate both aspects (ie, speed and ability to recover). Indeed, there is a lot of commonality in the understanding of resilience in the three areas of psychology, ecology and disaster relief.

In engineering the take on resilience is somewhat different. Indeed, engineers more commonly use the term ‘robustness’ with a connotation of designed resilience. It differs from the other three uses in that it assumes that the kinds of disturbances and shocks are known and the system being built is designed to be robust in the face of these shocks.

Resilience thinking

The ‘resilience’ that is being invoked in vision and mission statements relating to Australia’s environment is largely based on the idea of ecological resilience, and it’s all about the ability to recover.

The science underpinning our understanding of ecological resilience is often referred to as resilience thinking. The definition of resilience here is: the capacity of a system to absorb disturbance and reorganize so as to retain essentially the same function, structure and feedbacks – to have the same identity. Put more simply, resilience is the ability to cope with shocks and keep functioning in much the same kind of way. 

A key word in this definition is ‘identity’. It emerged independently in ecological and psycho-social studies, and it is both important and useful because it imparts the idea that a person, a society, an ecosystem or a social-ecological system can all exhibit quite a lot of variation, be subjected to disturbance and cope, without changing their ‘identity’ – without becoming something else.

The essence of resilience thinking is that the systems we are dealing with are complex adaptive systems. These systems have the capacity to self-organise around change but there are limits to a system’s self-organising capacity. Push a system too much and it changes its identity; it is said to have crossed a threshold.

The systems around us that we depend on (and are embedded in) are linked systems with social, economic and bio-physical domains, operating over multiple scales. To understand what enables these complex systems to retain their identity, what keeps them resilient, we need to appreciate the linkages between these domains and scales. We also need to understand how the system is behaving within each domain and scale, because over time these components go through their own cycles (known as adaptive cycles) in which the capacity for change (and the ability to hang on to their identity) shifts.

Many ideas, many insights

Resilience thinking involves all these ideas. It is the capacity to envisage your system as a self-organising system with thresholds, linked domains and cycles.

Each of these ideas take a bit of explaining, something I’ll attempt in upcoming blogs (for a good guide, see Resilience Practice*). However, when you begin engaging with ideas relating to a system’s resilience, you begin to appreciate the world in a different way.

Some of those insights have been for me that no-one is in control, and you can’t understand a system by understanding the components that make it up – complex systems have emergent properties (for example, the whole is greater than the sum of the parts).

We also need to appreciate that the narrower concept of ‘efficiency’ – ie, holding a part of our system in a state that delivers optimal returns (eg, food or fibre) without considering interactions with other domains or scales – leads to a loss of resilience, making it less likely that these systems will continue to deliver into the future. Efficiency is important but, by itself, it is not the solution to the challenge of sustainability.

We live in a complex world facing enormous challenges. Too much of our efforts so far have been directed to command-and-control approaches, techno solutions and improving efficiency. If the problems we were dealing with were simple and tractable, such approaches would work well. Unfortunately, our current approaches to sustainability are not working at all, and the problem is growing significantly.

Could it be we’re trying to solve the wrong problem? We’re managing a complex world as if it were a simple system.
