SFU Convocation Address – Global Resilience Requires Novelty

[On Oct 7th, 2011 Buzz Holling was awarded a Honorary Doctorate of Science at Simon Fraser University, in Vancouver, Canada. Below is his convocation address – editor]

Sixty years ago I was where you graduates are now, but graduating from the University of Toronto. By the time I got my PhD a few years later, I was well launched on a goal to understand population processes. It was the unknown that beckoned me and simple curiosity that motivated me.

The goal was to develop suites of models and experiments that could yield explanations and understanding that were simultaneously precise, realistic, holistic and general. For that time, just before computers became available, that was viewed as being unnecessarily complex. After all, one distinguished ecologist asked me, if you are interested in the time a ball takes rolling downhill, why worry about anything more than the height of the hill and its slope? General laws of physics will provide the answer.

But I was stubbornly curious about the path down the hill, the bumps and valleys that the ball might encounter and the momentary pauses as the ball encountered, or even, over several runs, created a shallow valley. That led to really delightful experimental studies of predators and prey leading to generalized models and sudden discoveries from them. The beasts used in the experiments depended on the question of the moment – Preying Mantis, deer mice, shrews, then birds, fish and stalking lions. The early computers and languages like Fortran suddenly provided the language that could use the experimental and field results. Models plus reality combined to yield broadened, generalized understanding of a small number of classes of predation.

That is when I discovered multi-stable states – population systems were not driven only by attraction to a single equilibrium state but, instead, there were several equilibrium states that determined their existence. And the goal for understanding and managing living resources and their physical world, was not sustainability but simple persistence. I learned, for example, that we could have detected and averted a collapse of cod populations off Newfoundland, avoiding the social and economic upheaval that in fact occurred. Or, we could have anticipated and avoided a western sub-continental outbreak of bark beetles that are now destroying stands of lodge pole pine throughout British Columbia and Alberta. Both of these examples were dominantly caused by the slow consequence of earlier development and exploitation, by the ingenious, but myopic foraging of fishers and harvesters, and by decades long fire protection policies.

Those slowly and invisibly led to reduced resilience, poising the systems on the edge of an instability state which began to unravel in a stutter of local spatial collapses and outbreaks, each stutter hidden by fast and innovative fishers and tree harvesters, until the whole system followed the stutters and collapsed at all scales.

That has forced a new paradigm that led to theories of resilience, to adaptive complex systems, to integration across scales from fast and small to very slow and big– from the needles of trees over months, to the boreal forest over millennia, That new resilience paradigm led to management of resources that was adaptive, where the unknown was large, alternatives could be proposed and monitoring was essential.

That is all part of complex adaptive system theory. It reflects humanity’s partial knowledge, fast inventions for dealing with surprises, and persistent learning.

It applies to the present turbulence in the world now. Slow economic processes have led us to the big surprises now appearing on a global scale. Financial collapse, debts threatening nations, European deep instability, and climate change.

Since the Berlin Wall fell, and the Soviet Union collapsed, corporations began to focus on fast economic variables and on globalization. That led to an emphasis on expanding efficiency but also to the emergence of slowly increasing debt, and hidden forces caused by diversified, subdivided and fragmented investments. No one knew where they were, or what they cost. That eventually triggered a collapse that exposed the reality that slow, invisible changes had decreased the resilience of the world economy. Globalization spread the collapse. What was presumed to be efficient began to be realized as being myopic.

At this turbulent time of crises, you and I have a real purpose. We need to help minimize and slow the spread of the collapses in the face of resistance from lobbies and from accumulated wealth. Banks and investment firms need regulation and a richer paradigm, but that need is opposed by the entrenched powers of corporations and banks that are caught in a rigidity trap. Nations of the European Union, and the Euro, need an integrated, multi-scalar inter-relationship, but one that now encounters the loss of resilience that comes in part from the inability to devalue a single nation’s currency and little control on debt inflamed growth. Carbon dioxide emissions need to be inhibited, but that encounters the opposition from the fossil fuel corporations- particularly oil.

Our aboriginal cultures and small communities here on the west coast are discovering and protecting treasured histories and traditions of local cultures. They now need to also add and create novel new ways to see and act beyond their traditional scales at the mouths of rivers and to connect to others across scales. Does fear stop them? Could their traditional theory (and myths) combine with adaptive resilience theory (and myths) as an emerging synthesis?

The answer is to keep trying, keep talking, keep communicating, but recognize it is a frustratingly slow process. Understand the traps- poverty traps like Haiti, rigidity traps like Fascism, lock-in traps of mega agriculture, and gilded traps from external subsidies.

And here is a program specifically for you. Encourage and support experiments, a multiplicity of experiments that search for and deepen new paradigms. Be entrepreneurs, alone and cooperatively together. And make the experiments global and cross scale. The internet and its novel ways of helping people to interact lets us reach or create groups of participants independent of where they live, ones from multiple patches and multiple time senses.

Many experiments will fail, but make them safe in their failure. Look for rare synergisms between a few successes. When enough people and experiences have accumulated, then protest publicly, non-violently and simultaneously against the defenders of the old paradigm that created the crash, the flip.

Make it our Big Arab Spring.

1) BBC News – Rivers of ice: Vanishing glaciers.- David Breashears retraced the steps of early photographic pioneers such as Major E O Wheeler, George Mallory and Vittorio Sella – to try to re-take their views of breathtaking glacial vistas.

2) Thai water management experts are blaming human activity.for turning an unusually heavy monsoon season into a disaster. NYTimes writes:

The main factors, they say, are deforestation, overbuilding in catchment areas, the damming and diversion of natural waterways, urban sprawl, and the filling-in of canals, combined with bad planning. Warnings to the authorities, they say, have been in vain

3) Chen et al’s conducted a metanalysis of published species response to ongoing climate change and found 2-3X faster movement than previous studies.  Their paper in Science – Rapid Range Shifts of Species Associated with High Levels of Climate Warming (DOI: 10.1126/science.1206432) estimated median rates of species movement were 11m gain in elevation/ decade and poleward movement of 17 km/ decade. They conclude:

average rates of latitudinal distribution change match those expected on the basis of average temperature change, but that variation is so great within taxonomic groups that more detailed physiological, ecological and environmental data are required to provide specific prognoses for individual species.

Wikipedia page on Social-ecological systems

I was pleasantly surprised to discover that wikipedia has a substantial and good page on the concept of social-ecological system.

Socio-ecological system – Wikipedia, the free encyclopedia:

A socio-ecological system consists of ‘a bio-geo-physical’ unit and its associated social actors and institutions. Socio-ecological systems are complex and adaptive and delimited by spatial or functional boundaries surrounding particular ecosystems and their problem context. [1]

A socio-ecological system can be defined as: [2](p. 163)

  • A coherent system of biophysical and social factors that regularly interact in a resilient, sustained manner;
  • A system that is defined at several spatial, temporal, and organisational scales, which may be hierarchically linked;
  • A set of critical resources (natural, socioeconomic, and cultural) whose flow and use is regulated by a combination of ecological and social systems; and
  • A perpetually dynamic, complex system with continuous adaptation. [3] [4][5]

Scholars have used the concept of socio-ecological systems to emphasise the integrate concept of humans in nature and to stress that the delineation between social systems and ecological systems is artificial and arbitrary. [6] Whilst resilience has somewhat different meaning in social and ecological context [7], the SES approach holds that social and ecological systems are linked through feedback mechanisms, and that both display resilience and complexity. [5]

I urge Resilience Science to go and improve it.

A global assessment of social science understanding of global environmental change

IHDP recently conducted a large-scale global survey of 1,276 scholars from the social sciences and humanities involved in human dimensions of global change research (the full survey report here is UNU-IHDP Survey Results 09 2011.pdf), which calls for a  “global assessment and synthesis of social sciences and humanities findings of relevance to global environmental change”, which is something that ecologists and earth system scientists have been requesting for years (see here and here).  This sounds like a great initiative and I hope it will be able to attract funding.  It would be a shame if it only includes social scientists, because global change research should be trying to understand the planet as an integrated system not reinforce disciplinary divisions.

The survey identified the highest priority areas for research as:

  1. equity/equality and wealth/resource distribution;
  2. policy, political systems/governance, and political economy;
  3. economic systems, economic costs and incentives;
  4. globalization, social and cultural transitions.

The report  concludes:

There was very strong support for the concept of a global assessment of social science and humanities research findings of relevance to global environmental change, in order to improve awareness of current research, strengthen collaboration, and develop policy-relevant material. From 88 to 92% of respondents supported such an assessment, whether they knew of IHDP or not, and whether their training was in the social sciences or environmental sciences, IT or engineering. Moreover, this support was backed up by a willingness to participate. From 49 to 59% of respondents—in all of the above-mentioned categories—said they were interested in participating, and an additional 32 to 34% in each categories said they would consider participating.
In brief, these results indicate that there is a large interdisciplinary group of scientists working on issues of global environmental change who feel that there is a strong need to integrate more social sciences perspectives, and who are willing to participate in the effort to do so. Their highest priority research areas were identified as equity and equality, and wealth and resource distribution; policy, political systems, governance, and political economy; economic systems, economic costs and incentives; and globalization and social and cultural transitions.
In response to this mandate, IHDP will convene a broad group of social scientists and humanities scholars to undertake a global assessment and synthesis of social sciences and humanities findings of relevance to global environmental change. Priority research areas will include the four identified by survey respondents (see above) as well as others developed by a Science Assessment Panel. The main questions to be addressed by the Assessment will include identifying the direct and indirect drivers of unsustainable behaviors, and figuring out how to leverage societal transformations towards social and environmental sustainability.

Loss of Old Arctic Sea Ice

Age of Arctic Sea Ice in February 2008. The February 2008 ice pack (right) contained much more young ice than the long-term average (left). In the mid- to late 1980s, over 20 percent of Arctic sea ice was at least six years old; in February 2008, just 6 percent of the ice was six years old or older.

Old sea ice, which had survived several summers, used to dominate the sea ice of the winter Arctic. However, today less than half of the sea ice at winter maximum has survived at least one summer.  NOAA’s climatewatch has a video of the loss of arctic sea ice.

Yukon Delta from Space

Yukon Delta

A great picture of the organic complexity of the Yukon River Delta from NASA EOS.  They write:

The Yukon River originates in British Columbia, Canada, and flows through Yukon Territory before entering Alaska. In southwestern Alaska, the Yukon Delta spreads out in a vast tundra plain, where the Yukon and Kuskokwim Rivers meander toward the Bering Sea.

The Enhanced Thematic Mapper Plus on the Landsat 7 satellite acquired this natural-color image of the Yukon Delta on September 22, 2002. Looking a little like branching and overlapping blood vessels, the rivers and streams flow through circuitous channels toward the sea, passing and feeding a multitude of coastal ponds and lakes.

The Yukon Delta is an important habitat for waterfowl and migratory birds, and most of the protected refuge is less than 100 feet (30 meters) above sea level. Over such low-lying, mostly treeless terrain, the rivers can change course frequently and carve new channels to find the fastest route toward the sea. The pale color of the sea water around the delta testifies to the heavy sediment load carried by the rivers.

Climate Stablization Wedges – an update, responses and critiques

A well know proposed strategy for reducing carbon emissions was the 2004 “wedges” paper in by ecologist Stephen Pacala and engineer Robert Socolow (Science DOI: 10.1126/science.1100103). For more on wedges see Carbon Mitigation Initiative website at Princeton.

Robert Socolow has recently published an update on the wedges paper, in Bulletin of the Atomic Scientists, which discusses the failures of their proposal, he reaffirms the wedges approach and argues that they should have presented their work differently – specifically:

…advocates for prompt action, of whom I am one, also bear responsibility for the poor quality of the discussion and the lack of momentum. Over the past seven years, I wish we had been more forthcoming with three messages: We should have conceded, prominently, that the news about climate change is unwelcome, that today’s climate science is incomplete, and that every “solution” carries risk. I don’t know for sure that such candor would have produced a less polarized public discourse. But I bet it would have. Our audiences would have been reassured that we and they are on the same team — that we are not holding anything back and have the same hopes and fears.

and he proposes that:

To motivate prompt action today, seven years later, our wedges paper needs supplements: insights from psychology and history about how unwelcome news is received, probing reports about the limitations of current climate science, and sober assessments of unsafe braking.

There are responses onThe Bulletin of the Atomic Scientists website and Climate Central that include the Nicholas Stern and others.

Andrew Revkin on DotEarth has an number of US and energy oriented comments from earth system scientist Ken Caldeira, my former colleague at McGill economist Chris Green and others as well as response from Socolow.

Rob Hopkins from Transition Town movement presents a view from local sustainability action.  He worries that the wedges approach can actually make our current situaiton worse – in Giving Robert Socolow a Wedgie (so to speak). He argues that systemic strategies that improve local resilience could be much more successful by addressing multiple issues that focusing on energy and CO2.

Socolow argues that part of the blame for the fact that the world hasn’t adopted the wedges approach can be laid at the door of the environmental movement, for being so upbeat and chipper about the impacts and not acknowledging that there will be ‘pain’ alongside the ‘gain’ (as it were).  …  I think it is far more likely that most of Pacala and Socolow’s wedges are, ultimately, unfeasible due to their own energy intensity and cost in a contracting global economy.

Socolow and Pacala’s wedges were conceived and proposed solely as responses to climate change.  Yet, of course, climate change is not the only challenge we face.  As the World Economic Forum’s recently-released analysis of the risks facing the world over the next 10 years identified, extreme energy price volatility and the fiscal crisis sit alongside climate change, closely followed by economic disparity, collectively leading the field in terms of risks we need to be building resilience to as a matter of urgency

More conceptual diagrams of social-ecological systems

Following up on my post yesterday on conceptual diagrams of social-ecolgoical systems (SES), below are some more SES conceptual diagrams from the journal Ecology and Society.

I did a google search that found a bunch of nice and not so nice diagrams in Ecology and Societyy, which is the main journal publishing research that uses the term social-ecological system (at least according to ISI’s web of science).  Below is a sampling of images, and below that a few examples.

Conceptualizing Social-Ecological Systems

I’ve recently been teaching about social-ecological systems and because I think it is important to conceptualize systems graphically these discussions caused me to reflect on the conceptual diagrams of social-ecological systems

Conceptualizing something as a social-ecological system hides some aspects of reality to focus on others. Social-ecological systems focus on the interactions and
Factors that distinguish social-ecological systems from other approach feedbacks between social and ecological, in particular how social and ecological alter one another and “co-evolve.”

As a systems approach it focuses on structures and processes, but because it comes from a resilience orientation in is particularly interested in how these structures persist and reorganize in response to shocks, gradual changes, or purposeful transformations.

Below are a number of different takes on conceptual diagrams of social-ecological systems that I think show some different aspects of social-ecological systems.

There are many other conceptual diagrams of social-ecological systems and I’d welcome any comments that point to other papers that have particularly interesting or different conceptual diagrams.

Resilience of Totnes

‘Town’ series on BBC2 examines the role of towns in the UK.

The last show in the series looks at the resilience of Totnes, the founding site of rapidly growing Transition Towns movement, which is represented locally by Transition Town Totnes.

The show focuses on the town, rather than the transition movement, but its focus on the resilience and deep history of Totnes is quite interesting. I especially found interesting how the town is connected to the utopian experiments of the nearby Dartington Hall, which is now home to the sustainability focused Schumacher College. The entire show is available on youtube.

The BBC describes the episode as:

A Saxon river town in South Devon, Totnes is one of the UK’s oldest towns. It has seen tough times through its long history, but adversity has taught it to innovate. Geographer and adventurer Nicholas Crane visits the home of one of the greatest social experiments of the 20th century, and uncovers the test bed for an ambitious new idea that aims to change our urban life forever.
