BiodivERsA3 and BiodivClim both address biodiversity conservation, nature-based solutions, and ecosystem governance in European overseas territories.
REGION REUNION
French overseas regional government providing island demonstration sites for biodiversity conservation, climate adaptation, and energy decarbonisation in the Indian Ocean.
Their core work
Région Réunion is the regional government of Réunion, a French overseas territory in the Indian Ocean. In H2020 projects, they serve as a real-world demonstration site and policy partner for island-specific challenges — biodiversity conservation in tropical ecosystems and energy transition for isolated island grids. Their value lies in providing access to a unique European overseas territory where climate adaptation, nature-based solutions, and decarbonisation strategies can be tested under real island conditions with direct policy relevance.
What they specialise in
MAESHA focuses on smart, flexible solutions for decarbonised energy in Mayotte and other island territories, including renewable energy and storage.
BiodivClim explicitly links biodiversity with climate change mitigation and adaptation in socio-ecological systems.
Both BiodivERsA3 and BiodivClim emphasize governance processes, policy dialogue, and transdisciplinary approaches involving regional authorities.
How they've shifted over time
Their early H2020 work (2015-2018) centred on biodiversity fundamentals — ecosystem services, conservation, restoration, and building science-society dialogue in European overseas territories. By 2019-2025, they shifted toward applied challenges: climate change adaptation, socio-ecological governance, and island energy transition including renewables and storage. The trajectory shows a clear move from understanding island ecosystems to actively decarbonising and climate-proofing them.
Moving from passive biodiversity research participation toward active island decarbonisation and climate resilience demonstrations — expect growing involvement in clean energy and adaptation projects.
How they like to work
Always a participant, never a coordinator — consistent with their role as a regional public authority providing territory access and policy context rather than leading research. Despite only 3 projects, they have worked with 70 partners across 32 countries, reflecting participation in large ERA-NET cofund networks and an Innovation Action consortium. This makes them easy to integrate into large consortia where a real-world island demonstration site with government backing is needed.
Through just 3 projects, Région Réunion has connected with 70 partners across 32 countries — a remarkably wide network driven by their participation in large ERA-NET cofund programmes. Their geographic reach spans Europe broadly, with a natural link to other island and overseas territories.
What sets them apart
Région Réunion offers something few European partners can: a tropical island territory under EU jurisdiction, providing a living laboratory for testing biodiversity, climate adaptation, and energy solutions under island-specific constraints. As a regional government, they bring direct policy authority and can facilitate real deployment — not just research. For any project needing an island demonstration site with institutional backing in the Indian Ocean, they are a rare and valuable partner.
Highlights from their portfolio
- MAESHATheir largest funded project (EUR 70,000), focused on smart energy decarbonisation for island territories — marks their pivot into applied energy transition.
- BiodivClimBridges biodiversity and climate change at the transnational level, reflecting the region's evolution toward integrated climate resilience.
