Resilience Thinking: 
Preparing for the Unknown 
Nathan Albritton
Background 
• Earth is dynamic 
– Change is inevitable 
• Scientific inquiry has allowed us to 
better understand our world 
• However, there will always be surprises 
– The world is inherently unknowable 
2 
"The only true wisdom is in knowing you know nothing." 
"The fool doth think he is wise, but the 
wise man knows himself to be a fool." 
-William Shakespeare 
-Socrates 
“To know that you do not know is the 
best. To pretend to know when you do 
not know is a disease.” 
-Lao-Tzu
What is Resilience? 
• The ability of a system to perform its 
desired function after a shock 
• Equilibrium Resilience 
– Maintain steady-state 
• Engineering Resilience 
– Time for system to return to normal 
• Ecosystem Resilience 
– How much a system can be disturbed 
3 
Earth in Balance?
Are Stability and Balance Good Things? 
• Two key (and faulty) assumptions: 
– There is an ideal stable state or 
situation that we have to maintain 
– We know better than nature

Seawalls and Sand Loss 
(Pilkey et. al., 1996) 
(Star Wars)
History of Resilience Thinking 
• Ecologist C.S. ‘Buzz’ Holling ‘discovered’ 
the notion of resilience in the 1970s 
• Major outbreak of spruce budworm 
– Destroyed balsam fir trees in Eastern Canada’s 
mature forests; yet left young trees alone 
– Six major outbreaks since 1700s 
• Canadian government reacted with 
pesticide spraying 
– Caused destruction of predator / budworm 
relationship 
– Whole forests on verge of outbreak 
– Locked-in to using increased levels of pesticides 
• Budworm outbreaks acted as natural 
rejuvenator of spruce-fir forests

Resilience Thinking 
• Resilience Thinking is based on two premises: 
– Humans and nature are part of a strongly couple and coevolving 
“social-ecological” system 
– Systems do not respond to change in a linear, predictable fashion 
6
Adaptive Cycle 
• Growth or exploitation (r) 
– New opportunities and available resources 
exploited 
– Pioneers/opportunists successful 
• Conservation (K) 
– Energy stored, material accumulates 
– Increasing dependence on existing 
structure 
– Increasingly stable/rigid, loss of flexibility 
• Collapse or release (omega) 
– Resources released 
– Connections break 
• Reorganization (alpha) 
– Destruction opens up new options 
– Novelty, invention, experimentation 
possible (i.e. evolution) 
7 
Adaptive Cycle 
(resalliance.org) 
Panarchy 
(resalliance.org)
Panarchy 
• Panarchy – A hierarchical set of 
linked/nested adaptive cycles, and 
their cross scale effects of different 
levels of a system 
• Smaller and faster adaptive cycles are 
areas for experimentation 
• Playing / experimenting with larger 
and slower adaptive cycles can have 
deep, long-term effects (e.g. 
anthropogenic climate change) 
8 
Scales and Panarchy 
(Ecology and Society)
Basins of Attraction 
• Regions in which a system tends to 
remain 
• More than one basin of attraction 
for any given system 
• Focuses on regime shifts and 
tipping points, which can tip a 
system into another state which 
is difficult or impossible to recover 
from 
• “How much shock can a system absorb before it transforms into 
something fundamentally different?” (Folke, 2009) 
9 
Ball and Cup Heuristic of 
System Stability 
(Environmental Governance)
Stability Landscapes

Dealing with Climate Change 
• Holocene has been a period of flourishing human civilization 
• Temperature unlikely to stay the same even if no anthropogenic effects 
• Impossible to predict future 
• However, we can learn, adapt, and evolve through experimentation in 
smaller, faster scales in the panarchy 
11 
Temperature Fluctuations over Human History 
(SeedMagazine.com)
Dealing with Climate Change (cont’d) 
12 
• Climate change is a potential large-scale 
source of change in many ecosystems 
– Great potential to change stability landscapes 
• Resilience Thinking can be used to help 
systems maintain essential functions - guided 
transition 
– Humans are part of nature, evolving along with it 
• Will require adaptive form of governance 
– Experimentation at local level 
– No ‘one-size fits all’ solutions 
– Increased participation; not just rely on “experts” 
– Increased information flow 
– Bolstered social networks / social capital
Key Take-Aways 
• Resilience Thinking is a form of systems thinking 
– Everything is connected 
• Resilience Thinking embraces uncertainty and accepts risk as inevitable 
• Resilience is not just about absorbing disturbance 
– Also about the capability to self-organize and the capacity to learn, adapt and 
transform 
• Resilience Thinking encourages a greater awareness of complex systems, 
their interacting parts, and the ability to cope with changes without the 
need to accurately predict what a change will bring 
• Embrace change, nothing is static 
– The key is not equilibrium but fluctuation and change 
– There is no sustainable optimal state, change will happen 
– Life is full of surprises; Embrace change and dance with it, no-one's in control

Notes de l'éditeur

  1. Resilience at one scale does not necessarily mean resilience at all scales. http://www.ecologyandsociety.org/vol7/iss1/art14/figure2.gif
  2. “basins of attraction” – region in state space in which a system tends to remain Crossing a threshold may move a system into a new state, but identifying such thresholds is very difficult (Shcheffer et al. as cited in Lin & Petersen, 2013) “…social-ecological systems have a number of thresholds at different scales and in both the ecological and socioeconomic domains.” (BH Walker et al., 2006) “There is ample evidence from local to regional-scale ecosystems, such as lakes, forests, and coral reefs, that gradual changes in certain key control variables (e.g., biodiversity, harvesting, soil quality, freshwater flows, and nutrient cycles) can trigger an abrupt system state change when critical thresholds have been crossed” (Carpenter et al. 2001, Folke et al. 2004, Hughes et al. 2007, Scheffer 2009 as cited in Rockström & Steffen, 2009)
  3. “stability landscapes” – the different basins of attraction that a system may occupy and the boundaries that separate them http://www.resalliance.org/images/key_concepts/fig1a.jpg

  7. Resilience Network – “…an ephemeral research group that produced four edited volumes, each of which explored different interdisciplinary connections.” Resilience Alliance – “The Resilience Alliance, an international consortium of 15 research groups that grew out of the Resilience Network. One specific objective of the group is to bring together ecologists, economists, political scientists, mathematicians, social scientists, and archaeologists to begin an interdisciplinary assessment of the ideas developed in previous works.”
