From food web models to political decision-making: what lessons can be drawn from cumulative impact simulations in the Bay of Seine? Starting from the idea that the “network” object makes it possible to crystallize interdisciplinary research, we seek to exchange methods and concepts to answer the question: in what way can food web models influence political decisions? For this, the studies carried out in the Bay of Seine on various cumulative impacts (offshore wind project, port dredging deposits, aggregate extraction, port extension, fishing), based on observations before / after impact orsimulated scenarios, will be revisited in order to identify points useful for political decision-making.
