Representing cultural change in ABM of landscape-scale socio-ecological systems

  1. 1. http://landscapemodelling.net James D.A. Millington Dept. of Geography, King’s College London Representing cultural change in ABMs of socio-ecological systems
  2. 2. Agricultural Transitions http://landscapemodelling.net
  3. 3. Agricultural Transitions  Policy shifts emphasising ‘non-productive’ uses of the land (multi-functionality) http://landscapemodelling.net Farming Intensity Productivity Low High Environmental Sustainability High Low Diversification High Low Strong Multifunctionality Weak Multifunctionality
  4. 4. Modelling Transitions http://landscapemodelling.net “…one key paradox is that the grand challenges appear to involve changes in behaviour, which represent not a continuous evolution of current patterns of behaviour but often radical shifts.” Heppenstall et al. (2012) p.744
  5. 5. Modelling Transitions http://landscapemodelling.net “How we use models which simulate current patterns of behaviour which need to change if the key issues are to be resolved poses enormous difficulties for implementing and using models that are based on current and past patterns of behaviour.” Heppenstall et al. (2012) p.744
  6. 6. Beyond Agent Types? http://landscapemodelling.net Valbuena et al. (2008)
  7. 7. Agricultural Transitions  Policy shifts emphasising ‘non-productive’ uses of the land (multi-functionality) http://landscapemodelling.net Farming Intensity Productivity Low High Environmental Sustainability High Low Diversification High Low Meaning of ‘Farming’ and ‘Agriculture’ More than food and fibre production Solely food and fibre production Strong Multifunctionality Weak Multifunctionality
  8. 8. Agricultural Transitions  What does it mean to be a farmer?  Burton and Wilson (2006) introduced social psychology theory into analysis http://landscapemodelling.net “No farmer got income from anything except farming”
  9. 9. Social Psychology Theory  People hold multiple self-concepts within their self-identity in a hierarchy (Stryker and Burke 2000)  Farmer: Producer, Agri-business person, Conservationist, Diversifier  People attempt to express their identity through their behaviour  Identity changes slowly to match social network if behaviour cannot match identity http://landscapemodelling.net
  10. 10. Farmer Social Psychology http://landscapemodelling.net
  11. 11. Agent-Based Model  ... of Farmer Identity and Behaviour http://landscapemodelling.net
  12. 12. Prices http://landscapemodelling.net
  13. 13. Prices http://landscapemodelling.net
  14. 14. Spatial variation http://landscapemodelling.net Gradient Quarters
  15. 15. Spatial variation http://landscapemodelling.net
  16. 16. Neighbourhood rules http://landscapemodelling.net Cannot Ignore Neighbours Able to Ignore Neighbours
  17. 17. Neighbourhood rules http://landscapemodelling.net Cannot Ignore Neighbours Able to Ignore Neighbours
  18. 18. Initial Observations  Initial (productivist) identities are stubborn to change and require external perturbation  Spatial distribution of resources can influence transitions between agents  Rules for social network formation influences which transition towards alternative identities http://landscapemodelling.net
  19. 19. Empirical Challenges  Identity Change  How to parameterise rates of identify change?  Different self-concepts expressed in different situations (including when talking to researchers!)  Social Network  Vast amount of data needed  Who knows whom? How often do they meet? What do they do when they meet? etc… http://landscapemodelling.net
  20. 20. Decisions and Identities  Social Psychology Theory  Identity has multiple, hierarchical self-concepts  Identity expressed through behaviour  Changes respond to social network when behaviour cannot reflect identity james.millington@kcl.ac.uk http://landscapemodelling.net http://modelingcommons.org/browse/one_model/3442
