Booklet presents the results and projects 2021-2026

Through the six calls for proposals launched by Biosefair and the annual support provided for doctoral dissertations, a research community has taken shape and made progress on a variety of topics by bringing together numerous disciplines and research groups. This booklet presents the results of completed research tracks and dissertations, as well as overviews of ongoing research tracks and dissertations.

Isoetides

ISOÉTIDES - Genetic and taxonomic diversity of isoetids communities of Aquitaine’s coastal shallow lakes

Know more

Lakes and ponds of the Aquitaine Atlantic coast are unique natural ecosystems, not only at the national but also at the European scale. These systems host a high taxonomic diversity, especially for aquatic plants. Indeed, isoetid communities represent a set of species with high conservation value, also including one endemic species. These communities are however highly threatened, especially by anthropogenic activities, and most of the coastal Aquitaine’s lakes have already experienced their extinction. Knowledge on these species is still however scarce, particularly concerning their genetic diversity. While conservation and restoration actions are emerging with the redaction of a National Plan for preserving these communities, understanding their genetic diversity, their relationships with taxonomic and functional diversity appear as a major issue.

Biodiversity and ecosystem services

After a COP15 on biodiversity with mixed results - better than expected, not strong enough for what needs to be done - scientific research such as that conducted at INRAE is more necessary than ever. It feeds into the stream of scientific results from around the world, documenting the extent of biodiversity degradation that is jeopardising the provision of associated ecosystem services, and identifying appropriate ways of slowing it down. However, the COP also clearly shows that political interactions largely determine the scope for action. In this respect, research is also urgently needed to gain a better understanding of these negotiation processes in order to develop more effective global and local biodiversity governance arrangements that are tailored to the challenges of agriculture, food and social well-being.

The BIOSEFAIR metaprogramme aims to support the deployment of such research within INRAE so that the very substantial sum of results produced on biodiversity and ecosystem services leads to proposals for transforming the systems in place, going beyond a comprehensive analysis.
This is a difficult task and a high ambition, commensurate with the stakes involved, but also with the very rich capabilities that are present within INRAE.
