JUNN, digital twins to simulate and anticipate the effects of climate change in France
As part of France 2030, Mathieu Lefevre, Minister for the Ecological Transition, Anne Le Henanff, Minister for Artificial Intelligence and the Digital Economy, and Bruno Bonnell, Secretary General for Investment, in charge of France 2030, have announced the State's investment under France 2030 to launch the JUNN project.
Initiated by IGN, Cerema and Inria, this programme aims to provide France with sovereign tools capable of cross-referencing a wide range of heterogeneous data, to visualise French territories and simulate their evolution, particularly in the context of climate change.
The future digital twins of French regions will facilitate scientifically informed decision-making by local authorities and public bodies, and will enable more precise and proactive management of regions.
The JUNN programme aims to bring together expertise and stakeholders to develop demonstrators for societal use cases, in the context of climate change and the ecological transition.
With JUNN, France is once again placing science at the forefront of planning decisions and the creation of enhanced regions.
BRGM, the French geological survey, partner of the JUNN programme
BRGM, an expert in the modelling of ground and subsurface resources, is one of the 14 members of the consortium of public and private partners that are contributing their expertise to develop the national digital twin.
The French geological survey is involved in the JUNN programme at three levels:
- by participating in the overall governance of the project and the construction of this new French ecosystem for digital twins;
- by contributing its expertise on data input for digital twins: processing and distribution standards, and data management based on FAIR principles (Easy to Find, Accessible, Interoperable and Reusable);
- by helping to remove a scientific barrier to the assimilation of data in numerical simulations, in a context of uncertainty about data and models. To this end, BRGM will supervise a 2-year post-doctoral project.
Pour aller plus loin
What is a digital twin?
Digital twins are virtual replicas of regions. They enable us to:
- visualise regions,
- test scenarios,
- anticipate crises,
- optimise public policies,
- support the energy transition.
Whether for assessing the impact of constructions on flood risk, or the effects of future roadworks on traffic, they are a valuable tool for informing political decision-making in the face of major regional challenges.
