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...

23. Januar 16:15 - 18:00Critical transitions in ecology - an overview

Ort: Gebäude 93, Raum E07

Veranstalter: Institut für Umweltsystemforschung

Kategorie: Systemwissenschaftliches Kolloquium

Referent: Dr. Egbert van Nes| In this talk I will introduce the concepts of critical transitions and resilience in natural systems. My main example is the ecosystem of shallow lakes, where we found evidence that these can have two alternative states: the clear water state dominated by aquatic vegetation and the turbid water state dominated by algae. I will argue that the positive self-enforcing feedback of vegetation is crucial for the existence of the alternative states. For lake management...
