09. Januar 16:15 - 18:00Mental models of complex dynamic systems: The case of Lake Victoria

Ort: Gebäude 93, Raum E07

Veranstalter: Institut für Umweltsystemforschung

Kategorie: Systemwissenschaftliches Kolloquium

Referent: Dr. Karlijn van den Broek|

Mental models comprise people’s understanding of complex systems. These perceptions often vary widely across different people, while they greatly influence daily decision-making. We have investigated mental models at Lake Victoria, where the Nile perch stock has been declining in the past decades, due to a complex interplay of ecological, social and institutions factors. A novel approach for mental model elicitation was developed and validated at Lake Victoria to capture fishers’ perceptions of the dynamic processes of the Nile perch stock. This presentation will report on the use of this method and its validation in comparison to interview data. Moreover, I will show the mental models of the fishers and relate the complexity and focus of the mental models to individual differences across the fishers. The findings of this study will be discussed in relation to mental models of other conservation challenges as well as how these findings can inform policy that aims to address such issues.
