Produced for the ILK dialogue workshop (11-13 January 2016, UNESCO Headquarters, Paris) organized within the framework of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), this film presents extracts from interviews with three reindeer herders from the Sami community of Sirges in Jokkmokk, Sweden. The herders attest to the importance of biological diversity for their herding livelihood and their dependence on the health of the boreal forest ecosystem. They describe the practices that threaten herding along with the remaining stands of old forest, and their conflicts notably with industrial forestry. Expressed in other terms, they analyze the ecosystem services provided by the biodiversity of their subarctic forest milieu, and confirm that any threat to the biodiversity upon which they and their herds depend, is a threat to their way of life.

Etienne Hainzelin presents the main sorts of ecosystem services evidenced by the Millenium Impact Assessment (2005). He shows that, during the last decades, the development of an industrial agriculture especially took place by the replacement of a part of those ecosystem services by the use of fertilizers and pesticides.

Christian Chaboud presents some models and issues related to the economic approach of fisheries and marine resources. He especially comes back to the Gordon Schaefer model, and to the economic assessment of the ecosystem services.

Christian Amblard proposes a definition of the biodiversity, which he comprehends from the functional angle. After an highlighting of this biodiversity dynamics, he presents the ecosystem services approach.
