19th Quarterly Meeting of SCO France
Human and climatic pressures are combining to threaten all ecosystems, on land, in the air and in the ocean.
|
On Tuesday 2 December 2025, during the 19th SCO France Quarterly Meeting, three SCO projects demonstrated how they are using satellite data to mitigate pressures and preserve our environments. Replays. |

Light pollution disrupts the functioning of the living world and contributes to energy waste. In this context, ORENOS is developing an indicator of the quality of artificial night-time lighting in the Haute-Savoie region (France) based on daytime and night-time satellite imagery. This indicator will enable local decision-makers to prioritize their actions for adapting, renovating or switching off lighting. |
|
To remember
- Satellites used:
- These data enable the project to develop:
- artificial lighting quality indicators to locate the brightest areas, characterize the main types of light sources, detect malfunctions and identify the main private contributors;
- Biodiversity pressure indicators which, when combined with other information such as black grids and ecological corridors, will enable the identification of priority areas for lighting reduction.
- ORENOS makes it possible to study the public and private lighting infrastructure of an entire department.

Despite their very different nature, the feedback loops between dry periods and heavy rainfall weaken the soil and increase runoff. To help rural areas reduce the impact of these two hazards, ATTEST works to provide local decision-makers with ready-to-use prevention services, including the prioritization of areas for intervention and recommendations for preventive development measures. |
|
To remember
- Satellites used:
- Sentinel-2 to detect changes following an event and locate the most affected areas
- SPOT6 and Pléiades to analyze and interpret these changes
- These data are cross-referenced with geographical information about the locations (topography, land use, slope, soil science), as well as predictive models of exposure to hazards.
- The results are presented in 3D maps to locate runoff channels and agricultural plots generating runoff, as well as the locations and infrastructure most at risk from them (roads, homes, exposed agricultural plots), making it possible to identify where to install preventive measures to slow down, channel runoff or promote infiltration.
- The system's database brings together numerous methodologies, solutions, feedback from different regions, etc. to help find solutions that are recognized as effective in similar watersheds.

Did you know that species are disappearing at a rate 100 to 1,000 times higher than the natural rate? As coastal biodiversity is considered to be among the most vulnerable, BioEOS is developing observation tools and innovative indicators to characterize its status and improve conservation measures. Its first demonstrator concerns the south-western Indian Ocean region. |
|
To remember
- BioEOS promotes synergy between multispectral (Pléiades, Pléiades Neo, Sentinel, Venus) and hyperspectral (EnMAP and PRISMA) data
- These data are used to extract indicators of coastal biodiversity health in order to analyze its spatio-temporal dynamics and generate large-scale change maps.
- The project has already generated numerous products such as chlorophyll, suspended matter, temperature and bathymetry, seagrass mapping and coral vitality, a new index (previously only obtained in the field).
- Cross-referencing of the various indicators shows that macroalgae are signs of ecosystem degradation, so the project will focus on characterizing them.

Launched in June 2021, the SCO France Quarterly Meetings are regular events designed to engage the community and allow each project to showcase its progress, inspire others and create synergies.
Since July 2025, ClimateSCOpes has been offering similar events for international projects, with two webinars per year.
