Telecoupled Systems are Rewired by Risks

The authors examine how risks operate within telecoupled systems, globally interconnected socio-environmental systems linked through trade, migration, financial flows, environmental processes, and other connections. Rather than treating connectivity as fixed and examining only how shocks propagate through networks, they argue that risk itself can rewire these systems as individuals and institutions respond through supply diversification, trade restrictions, insurance, contracts, cooperation, and other risk-management strategies. These responses can strengthen, create, weaken, or eliminate connections, redistributing risks across places and sometimes generating unintended feedbacks that amplify systemic risk. The paper highlights major challenges in understanding these dynamics, including the difficulty of perceiving distant risks, the greater number and variety of risks in telecoupled systems, and the complexity of anticipating how risks propagate and transform across interconnected systems. It calls for integrating behavioural research with network science, agent-based modelling, and other risk-aware models that treat system connectivity as dynamic, arguing that models that assume fixed connections may misrepresent how risks are distributed and who ultimately bears their consequences.
