Regime shifts are large, abrupt and persistence critical transitions in the function and structure of (eco)systems

Coral transitions

Regime shifts are large, abrupt and persistence critical transitions in the function and structure of (eco)systems

Purpose

  • To provide a high quality synthesis of different types of regime shifts in SES
  • To facilitate comparison
  • Focus: regime shifts that have large impacts on ecosystem services i.e. matter to people
  • Target audience: Scientist, assessment processes, lecturers, students, practitioners, policy-makers

    Biggs, et al. 2018. Ecology & Society

www.regimeshifts.org

Critical research gaps

  • What different regime shifts can occur in different SES?
  • What are the major drivers of regime shifts?
  • What are the impacts of regime shifts on ecosystem services and human well-being?
  • How can regime shifts be managed?
  • How are different regime shifts interconnected?

Human-centered operational definition:

“Large, persistent (and usually abrupt) shifts in the set of ecosystem services produced by a SES” —Oonsie Biggs

Andersen, J. et al. Trends Ecol Evol. (2009).

Abruptness affects the capacity to adapt to changes

Human-centered operational definition:

“Large, persistent (and usually abrupt) shifts in the set of ecosystem services produced by a SES” —Oonsie Biggs

Foley, J et al. Science (2005)

Abruptness affects the capacity to adapt to changes

Criteria for selecting regime shifts

  • Evidence of potential impacts on ecosystem services or human well-being
  • Evidence of feedbacks mechanisms that reinforce different regimes
  • Persists time scale relevant for society, it matters for management

Regime shift Analysis framework

Biggs, et al. 2018. Ecology & Society

Step 1: Define the system

Identify a relevant (social-ecological) system

Step 2: Identify different regimes

As reported in the literature

Step 2: Identify different regimes

“Beatuty The system boundary is the the eye of the beholder” – Not really…

Blondel et al, 2010

Rocha et al 2020 Mapping social -ecological systems ERL

Step 3: Identify key ecosystem services

associated with each regime & stakeholder groups that benefit from them

  • Forest
    • Carbon sequestration
    • Game (hunting)
    • Timber
    • Species biodiversity
    • Conservation & tourism
    • Sacred places
    • Mining (minerals)
    • …
  • Savanna
    • Carbon sequestration
    • Cattle ranching
    • Conservation and tourism
    • Species biodiversity
    • Sacred places
    • Crops production
    • …

Step 3: Identify key ecosystem services

associated with each regime & stakeholder groups that benefit from them

Papers on regime shifts are not necessarily explicit about their impacts on ecosystem services. But you can find papers on ecosystem services that matches your identified regimes or areas of study

Step 4: Identify feedbacks

Step 5: Identify drivers

“Any natural or human-induced factor that directly or indirectly causes a change in an ecosystem” – MEA, Nelson 2006

Step 5: Identify drivers

Step 5: Identify drivers

Paraguay 2000 - 2015 trade3 trade4

  • Spillover effects & Teleconnections:
    • Soybean related commodities expansion
    • Cattle ranching displacement across countries
    • Increase deforestation and land use change somewhere else

Step 6: Identify management options

  1. Managing deforestation
  2. Managing fragmentation
  3. Managing fire (natural / anthropogenic)
  4. Managing herbivores

Step 7: Other useful information

  • Context:
    • Land use
    • Ecosystem type
  • Evidence:
    • Source of evidence (models, experiments, observations)
    • Confidence of existence and mechanisms
  • Scales:
    • Space
    • Time
    • Reversibility

Caveats

  • Based on literature review – biased by what has been studied
    • More studies in aquatic systems
    • Under reporting in developing/low population areas
    • Impacts on ecosystem serives and human well-being often not reported
  • Definitions change from field to field
  • Under representation of social dynamics
  • Science is slow and contested
  • But there is demand for regime shift assessments (IPCC, IPBES, Arctic Council, CBD, European environmental agency, GTPR)

Assignment

Goal: Improve the coverage by coding new case studies for the RSDB

  1. Form groups of 3-4 people and chose a regime shift
  2. Search for papers about your regime shift (Scopus, WoS, OpenAlex)
  3. Check that your papers have not already been coded
  4. Group work (due Friday 29th November):
    • Annotate the CLD (individual hand in)
    • Annotate a template (group hand in)
  5. Group work:
    • Video presentation: How are your case studies reflected on the generic regime shift description? What is missing / context dependent? Use CLD to highlight differences (due Thursday 5th December).
    • Watch two videos and provide feedback to others (due Friday 6th Dec).

Final assignment (individual)

Due 10th December 12.00

  • Option 1: Code at least 10 new case studies level 1 depth. Each case study is a paper with a regime shift occurrence in a specific place and time.

  • Option 2: Code at least 5 new case studies level 2 depth by adding detail descriptions. Here you should write text suitable for the website (no jargon) and emphasize what makes the case special (e.g. how is it different from the generic description).

  • Option 3: Code at least 3 new case studies level 3 depth by adding a regime shift analysis. This should include the review of multiple papers about the same case studies and the text should be different from what is already described on the generic case. Please emphasize what makes the case special.

Causal diagrams

“CLDs are a technique to map out the feedback structure of a system” – J. Sterman 2000

Causal links

“a positive link means that if the cause increases, the effect increases above what it would otherwise have been, and if the cause decreases, the effect decreases below what it would otherwise have been […] A negative link means that if the cause increases, the effect decreases below what it would otherwise have been”

— Sterman, 2000



Causal links do not describe the behavior of variables, but only the structure of the system. They describe what would happen if there were changes.

Polarity

Links polarity should be unambiguous. If you have problems assigning a clear polarity to a link, it often means that there is more than one causal pathway connecting two variables.

Feedbacks

Feedback means that once a signal entered the loop, some part of the output is feed back to the input, resulting on either an amplification or damping of its own signal.

Variable names & delays

  • Variable names should be nouns and must have a clear sense of direction, preferable positive (e.g. use happiness instead of unhappiness).
  • The actions (verbs) should be captured by the causal links.
  • Delays give system inertia and can create oscillations in the aggregated behavior.

Human behaviour and social dynamics

  • Balancing feedbacks often represent goals, desired states.
  • The difference between expectations and the actual state of the system.
  • Goals are also prone to delay dynamics, in such case, to delay of information

Castillo & Saysel. 2005. Simulation of common pool resource field experiments: a behavioral model of collective action

Where to stop??

  • Human working memory is 7 (+/- 2) variables
  • Too much detail makes difficult to grasp the main dynamics, the main feedback loops interacting.
  • Too little detail makes it hard for the non-expert to assess the plausibility and realism of the model.

Limitations

  • CLD obscure the accumulation process of the system, its stock and flow structure
  • If you reduce the income flow, it does not reduce the level of beer in the glass.
  • Hidden loops and net rates are a general problem to all model forms including CLD, stock-flow charts, or plain equations.

Summary

  • Regime shift database
    • What is done, uses
    • Future directions
  • Assignment
    • Individual and group work
    • 3 options
  • Opportunity to contribute beyond class
  • Don’t underestimate your master’s thesis
