Relate two concepts: Regime shifts, transformations
- Both share roots in resilience thinking, panarchy
1. Operationalizing the regime shift concept - Reinette "Oonsie" Biggs
2. Transformations and regime shifts: Links, similarities and differences between these concepts - Per Olsson
3. Anthromes as social-ecological systems: mapping regime shifts globally - Erle Ellis
4. Social-ecological regime shifts a useful concept? Trajectories vs. Regime Shifts - Kasper Kok
5. Regime shifts in social-ecological systems over historical time: examples from France - Carole Crumley
6. Traps and Transformations: Poverty in Sub-Saharan Africa - Elin Enfors
[1. Operationalizing the regime shift concept - Reinette "Oonsie" Biggs]
Millenniem Ecosystem Assessments surfaced regime shifts as concerns
- e.g. Coral reefs --> algae dominated
- Have biophysical examples, what other types of shifts?
- How many?
- How interconnected?
Regime shifts database
- Like an Encyclopedia of the Earth, a starting point
- Soil salination
- Bush encroachmen
- What are drivers, feedbacks, impacts, and response options (to prevent or to encourage)?
- Users: researchers, students, practitioners
Challenge: How to identify regime shifts?
- Definition: Large, persistent changes in the structure and function of a system
- Metaphor: ball and cup models
- See: Biggg set al. Sourcebook in Theoretical Ecology, in press
In practice, have time series of data, have to rely on that as to whether regime shift or a gradual change or something else
- Noisy data
- Doesn't tell whether it's external driver or a change in some internal feedback
- Regime shift with respect to what?
Have focused on a human-centered operational definition, based on ecosytem services
- Definition: Large persistent (and often abrupt) shift in the set of ecosystem services produced by an SES
- Biggs & Petersen in press; Foley et al. 2005, Science 309: p. 570-574
Three core criteria to select criteria:
- 1. Is there a large persistent shift in ecosystem services?
- 2. Does the shift persist on a timescale that matters for people (c.f. on a short basis, that policy-makers don't card about).
- 3. Established or proposed feedback mechanisms that reinforce the different regimes
Currently 15 examples of regime shifts online
- Building up as open source materials
Now starting to compare regime shifts
- Rocha 2010, M.A. Thesis
Questions moving forward
- How to conceptualize regime shifts in SESs? Large persistent changes, e.g. land uses
- Social feedbacks that reinforce regime shifts (e.g. identities)
- Can we think of examples of transformations?
Rocha on Tuesday 11 a.m., room 241 Ventana, will speak on drivers of regime shifts
[2. Transformations and regime shifts: Links, similarities and differences between these concepts - Per Olsson]
- Chapin et al. 2010
- System dynamics in the middle, e.g. New Orleans
- Learning interacts with dynaimcs and capital, impacting sensitivty
- Drivers and disturbances
- Outcomes could be (i) persistence, (ii) unintended (negative) transformation, or (iii) active transformations
Will focus on active transformations, specificially those that increase capacity
Want to understand patterns of transformation
- Multi-phase, multi-scale models
- (i) Preparing phase, (ii) navigating the transition, (iii) stabilizing phase
- Conventional management, may lead towards unsustainability and maybe a collapse
- May be a window of opportunity to move to a new trajectory
- Regime around ecosystem-based management as stabilizing
- Move towards a new regime?
What constitutes a transformation?
- Bundles of attributes?
- Ecological knowledge that needs to enter the process to get a change in trajectory
- Understanding feedbacks for regimes?
Sendzimir et al 2007 has been mapping feedback loops in water management in Tiscza River, Hungary
- Paradigm: "protect landscape from the river", fighting nature
- Another paradigm: "living with the river"
- How do we get a shift? Emerging networks around the new regime, as a shadow network outside the main decision-making arena, how is it unlocked, is it a smooth process?
Transitions in Socio-Technological Systems
- Transition people in Netherlands: Rotmans et al. 2001, Loorbach and Rotmans 2010, Geels and Shot 2007
- Steamships ...
- Take the social-ecological system perspective and socio-technological and socio-political to deal with transitions
- Teaming up with social innovation people, e.g. Frances Westley
- Develop theory
- Complexity view on regimes
- Much of regimes is based on linear thinking
[3. Anthromes as social-ecological systems: mapping regime shifts globally - Erle Ellis]
Was trying to understand patterns of human beings in ecology
- Can we look at anthropogenic as regions?
- Co we do a better job, limitations so far
Classic (wild) biosphere:
- Human biosphere, as anthropogenic bioomes
- Dense settlements, etc.
- Ecosystem processes
- Population density
- Land use
Worked in land in China
- Changes in population density
- Ester Boserup (1965) changes in the way people achieve sustenance from the land
Land use regimes: Ellis 2011, inspried by Billie Turner II
- Intensification, Boserup 1965
- Involution, Geertz
- Seminatural anthromes
- Used anthromes
- Tree and bare cover
Clustered into anthropogenic biomes
Classification models, where the categories change
- Used rule-based classification
- Look over 300 years, mostly shift to used from wildlands
Biospheres like tropical rainforests are now rare
- Can change to regime shifts
- Regrowth of forests in northeast U.S. from collapse of farming
- Attenuation, reduction of engineering of landscape
Can't see in 1700 to 2000, but see attenuation if look 1900 to 2000
- Can't be wild, because we have to live there
- Thus, anthropogenic
Modeling the anthropocene
- Global market influence, Verburg et al. (in preparation)
Working towards Anthromes 3
- Theoretical predictive model for emergence and transitions
- Waiting for better theory
[4. Social-ecological regime shifts a useful concept? Trajectories vs. Regime Shifts - Kasper Kok]
- Land Dynamics, Wageningen University
Fuzzy Cognitive Mapping: A tool to explore regime shifts
Conceptual models about whether potential thresholds and regime shifts exist
What are fuzzy cognitive maps:
- Not fuzzy sets for mathematics, not cognitive maps that are simple
- Simple influence diagrams, good for getting a feel about how a system works
- Give each of the nodes an input vector
- Define a matrix with feedback loops
Can be used in participative settings, to uncover stakeholder perceptions
Can be applied with teams of scientists
- To increase system understanding
Example of Brazil of agricultural expansion (deforestation): influence diagram of why
- Demand outside?
- Inside? squatting?
- Land use intensification, agricultural expansion, land speculation and land grabbing -- which are most important?
- Run scenarios
- high level of integration, can put in all factors we want
- Quick and dirty, will need other tools
- Time is ill-defined
Regime shifts are a useful concept
- Can help change perceptions
- But worries about whether they're real: a shift could depend on system boundaries
[5. Regime shifts in social-ecological systems over historical time: examples from France - Carole Crumley]
France from 1 BC
- 450 BC, Roman climate optimum, a warm stable period
Changes against geography
- 900-500 BCE sub-Atlantic period
- 300 BCE - 300 CE: Roman optimum, can drink the wine
- 500-900 CE: Vandal minimum, Nile freezes
Two millenia: 1000 BCE to 1000 CE
- Holocene well known
- Little ice age at end of Medieval
Land use changes
- Bronze age
- Iron age 800 BC to Norman conquest
- Deforestation begins in Iron Age, then reversed in Migration period
[6. Traps and Transformations: Poverty in Sub-Saharan Africa - Elin Enfors]
Research focus: Use water system innovations (e.g. rainfall) for improving yield levels, and to contribute to mulit-functional agro ecosystems
- SES can develop along different trajectories, with varying degrees of path-dependency
Poverty is persistent is sub-Saharan Africa
- Different welfare equilibria
History: expansion of agricultural land
- More frequent dry spells, signalling a changing disturbance regime
Strategies for dealing with drought
- 44% off-farm emplyment, etc.
- 42% off agro-ecosystem-based businesses
- 14% from savings
- Population growth
- Lower input / output ratio, less fallow land time
Leverage points for transformation
Fractal view, deeper gets more confusing
Linear thinking, blueprints from A to B
- Regime shift to uncover more complexity
Continuum of dynamics
Complex systems framework with some goals. Chronology.
- Need to abandon causation in non-linear systems
- Qualitative then make understandings
Navigating regime shifts? Transformation?
- Land use is resistent to change, even with changes in social regime
Regime shifts in information systems?
- This may change some of concepts
- Multi-scale isn't so crucial in information systems
Innovation research, people make a difference, they bring about changes. Innovators, key actors
- Less thinking this way in regime shifts, more in transformation
- Breaking out of traps, trying out innovations that others will follow
- Like chemists, chemical reactions
- Regime shift, in respect to what? e.g. fish, versus change in what people do with them; more tractable when focused on outputs from system
- Transformation works better in social science, regime shift doesn't work so well in social science
- Can see regime shift, whereas transformation is a process than may not be visible
Transformation as human driven? Lack of ability to get measures?
- Seeing changes in water in a marine system
- Working with stakeholders, helps to understand how systems work. Different for bureaucrats
