The AnaEE vision has been developed with scientists and various types of stakeholders. They defined the elements which would allow this infrastructure to bring the relevant scientific answers to fundamental and applied questions relative to the impact of environmental pressures on the functioning of ecosystems. The experimental nature of the AnaEE approach called for a definition of which types of platforms were needed and on which types of ecosystems. The necessary added values to be brought by AnaEE at the European level for various stakeholders were also defined. The future delivery of these added values called for the definition of 4 supra-national entities: a coordinating Central Hub and three Service Centres (Technology; Data & Modelling; Interface & Synthesis).
