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.

Swedish version with english subtitles : In Sápmi, a vast region of northern Europe also referred to as Lapland, Sami reindeer herders are experts about snow. To reach the ground lichen on which they feed in winter, reindeer need to dig through a snowpack whose properties constantly change throughout the winter period. For this reason, the Sami have developed a ‘snow science’ that not only encompasses, as linguists have often exclaimed, an exceptional diversity of terms to name and classify snow. They have also cultivated an intimate understanding of physico-chemical processes affecting the snowpack. In this film, a Sami herder digs a hole in the snow to analyze and describe how thermal exchanges have transformed the properties of the snow since the beginning of the season. He explains how an ice layer, which formed over the ground surface, disappeared subsequent to a period of warming to once more render the lichen accessible to grazing reindeer.

Version suèdoise, sous-titrée en français : Dans le Sápmi, vaste région du nord de l’Europe encore appelée Laponie, les Samis éleveurs de rennes sont des experts de la neige. Pour atteindre le lichen dont ils se nourrissent, les rennes doivent creuser le manteau neigeux, dont les propriétés n’ont cesse de se transformer tout au long de l’hiver. La science de la neige samie ne se limite pas à l’immense diversité des mots qu’ils utilisent pour nommer et classifier la neige qui a été soulignée maintes fois par les linguistes, elle montre également une compréhension intime des processus physico-chimiques qui sont à l’œuvre. Dans ce film un éleveur décrit les échanges thermiques dans le manteau neigeux depuis le début de la saison. En creusant un trou, il explique pourquoi la couche de glace formée sur le sol à la suite d’un redoux a disparu, rendant à nouveau le lichen accessible pour les rennes.
