  Enlisting Poincaré to save the world: geometry and the economic impact of ecological systems with tipping points

  • Florian Wagener, prés., University of Amsterdam

  Environmental interest conflicts, like climate change, connect physical and social dynamics. Positive feedback loops in the physical dynamics can be triggered by passing tipping points. The associated models are typically non-linear and it is impossible to even solve the optimal management problem analytically. Fortunately geometrical methods that go back to Poincaré can come to the rescue. They delineate in which situations the manager, instead of fine-tuning a single basic type of policy, has to make fundamentally different choices. The methods can be extended to dynamic environmental interest conflicts between several parties.
