Abstract:听Coupled social-ecological systems are becoming more widely studied, on account of their relevance to sustainability and their ability to exhibit novel dynamical regimes that are not observed in social or ecological systems in isolation from one another. This dynamical richness creates both challenges and opportunities for research. In this talk, I will present some mathematical models of social-ecological systems and characterize their regimes; discuss novelties that arise in the detection of early warning signals of tipping points in these systems; and show how hybridizing dynamical systems with deep learning can improve the detection of these early warning signals. Study systems include forest-grassland ecosystem mosaics, coral reef fisheries, social-climate systems, and COVID-19 vaccination. This work is motivated by questions such as: How do we know which ecological or social-ecological regimes are possible? How can we know when a tipping point leading to a new dynamical regime is near, and what happens afterwards?
