Quantification of interdependencies between economic systems and ecosystem services: An input-output model applied to the Seine estuary

► We built a regional input-output model and coupled it to external biological equations describing fish stock and habitats. ► We enlarged input-output modelling from sink and provisioning services towards the most vital category: supporting services. ► Results show that nursery restoration generates economic impacts on the sector level rather than on the macro-economic one. ► This suggests that restoration costs can be seen more as a problem of cost allocation than as a problem per se.
