The BIOSEFAIR metaprogramme aims to meet a dual challenge: the sustainable management of the services and functions provided by ecosystems (nurturing, regulating or socio-cultural) and the conservation and restoration of biodiversity as a whole, both to maintain the services it provides and for its intrinsic values. BIOSEFAIR studies a broad spectrum of services such as the contribution to climate change mitigation, pollination, crop protection, natural risk prevention and cultural services. This metaprogramme marks an evolution in the way in which this diversity of services is taken into account, by favouring an approach centred on the socio-ecosystems formed around agricultural environments, livestock systems, forest and aquatic environments.
