In this second part, discover the biodiversity of the oceans, from the coral reefs to the coastal lagoons. This biodiversity, of which the knowledge is still partial, is the subject of great attentions, by virtue of its importance in the main balances of the biosphere, but also by virtue of the favors it does for the human societies, beginning with the supplying of food resources. The ecosystem approach to fisheries is currently developed in this context, in order to reconcile those different preservation issues.

In this third part, you will discover the biodiversity of the terrestrial and continental aquatic environments. Those environments are extremely diversified and are subjected to very specific dynamics, like intermittent rivers or ecological successions of the forest environments. Some of those environments present important physicochemical variations, like the rivers, from the spring to the estuary. The biodiversity is very rich in those environments, and several preservation prospects are presented.

The biodiversity plays a key role in the development and the upholding of the agrarian practices all over the world. This biodiversity is related to the grown species and varieties, but also to the ecosystems where those farmings are established, starting with the soil. The recent evolution of those practices shows a considerable decrease of the structure and of the functioning of this biodiversity. In the short and medium terms, this is a threat for the food production capacities. In order to ensure a sustainable agriculture, Etienne Hainzelin points out the necessity to develop agrarian practices, which are more intense from an ecological point of view.

Jean-Dominique Wahiche evokes the law of the biodiversity and of traditional knowledge. On the basis of a definition of the heritage notion, he recounts the history of international negotiations about those questions, until the 2010 Nagoya protocol. He evidences the recognition and the accrued protection of this traditional knowledge.

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.

In this presentation, Jérémy Lobry defines the ecological features of the estuarine environments, which are transition areas between the ocean and the continental environment. He firstly highlights the quite poor biodiversity, and secondly the extremely important secondary productivity of those environments.

On the basis of the issues linked to the worldwide agricultural activity, Etienne Hainzelin explores the approach of the agroecology, especially the ecological intensification of the farming systems. He shows the interest of keeping the ecological services of the environments, but also all the issues of knowledge and research linked to this transformation.

Etienne Hainzelin and Alain Ratnadass take an interest in pests and diseases. It can be defined as the part of the biodiversity which goes against the production. They evidence the paradigm of eradication, still important today, but taking the risks linked to the use of pesticides into account, they examine how the biodiversity can fight those pests and diseases.

With Etienne Hainzelin and Eric Blanchart, we will discover the third biotic boundary: the soils. They give several data regarding their important biodiversity, and they relate this biodiversity with the good functioning of the agroecosystems.

Etienne Hainzelin presents the main sorts of biodiversity which are linked to the agricultural systems: support biodiversity and destructive biodiversity. He focuses on the first one, and shows that, in the recent history, the human populations concentrated on some 'elite' varieties, as part of an high-yield agriculture, to the detriment of a specific and genetic diversity, which was raised and enriched over the centuries.
