From 1 to 11 October 2021, BRGM took part in the 30th edition of the Fête de la science. Here is a look back at this event, including the participation of our scientists in the daily Science en direct programme hosted by L'Esprit Sorcier.

2021 Festival of Science: meet our ambassador!

The Festival of Science is 30 years old and this year's theme is the emotion of discovery. For the occasion, our ambassador, Caroline Prognon, head of the Knowledge, Imaging and Modelling of the Subsoil unit, shares one of the most exciting moments of her professional life.

Science live 2021 - Are you interested in switching to different energies?

For the 30th edition of the Fête de la science, the ‘Science live’ event offered a daily appointment, from 1 to 10 October 2021.

In the 1 october programme ‘Are you interested in switching to different energies?’, Mariane Peter-Borie, géologue au BRGM, chef du projet DEEPEGS, unité géothermie et stockage d’énergies, parle du potentiel de la géothermie, plus particulièrement de la géothermie profonde pour la transition énergétique. Elle évoque notamment le projet de forage profond qu’elle a coordonné en conditions extrêmes en Islande, où la température atteint 600°C à 4600 mètres de profondeur, et son intérêt (un forage dans un réservoir super chaud représente l’opportunité de produire au moins dix fois plus d’énergie qu’un forage d’exploitation présent aujourd’hui en contexte volcanique).

Science live 2021 - Natural resources: solutions for the future!

For the 30th edition of the Fête de la science, the ‘Science live’ event offered a daily appointment, from 1 to 10 October 2021.

In the 3 october programme ‘Natural resources: solutions for the future!’, Stéphane Loigerot, Head of the Risk Information and Services department, explains how digital solutions can provide services for geoscience, using the example of the MétéEauNappes application and the Géorisques website. The aim of MétéEauNappes is to forecast the state of water tables in the same way as the weather. The objective of this platform is to enable water resource users and decision-makers to better anticipate actions regarding the management of the resource, to better understand the phenomena and to avoid serious crises, such as having to stop irrigation or restricting access to drinking water.

Science live 2021 - Exploring the past and understanding the present!

For the 30th edition of the Fête de la science, the ‘Science live’ event offered a daily appointment, from 1 to 10 October 2021.

In the 10 october programme ‘Exploring the past and understanding the present!’, Caroline Prognon, head of the Knowledge, Imaging and Modelling of the Subsoil unit, and BRGM's ambassador for the 2021 Festival of Science, explains why geology helps us understand the past. The surface formations, between the soil and the unaltered geological layers of the subsurface, support human activity. The Quaternary surface formations contain the oldest traces of humankind and are an invaluable archive of its evolution and our past. This is where archaeologists dig. These areas, at the interface between the atmosphere and continental surfaces, are also valuable archives for reconstructing past climates, rainfall, major atmospheric circulation patterns, and the response of environments and populations to these climates. But for a long time geologists were not very interested in these formations. The situation changed and the detailed mapping of surface formations throughout France is underway.

Science live 2021 - Anthropocene: a small footprint for a human, a big one for humankind

For the 30th edition of the Fête de la science, the ‘Science live’ event offered a daily appointment, from 1 to 10 October 2021.

In the 11 october programme ‘Anthropocene: a small footprint for a human, a big one for humankind’ François Gemenne, researcher in political science at the University of Liège, author of the Atlas of the Anthropocene, explains live from BRGM in Orléans what is meant by the Anthropocene and spells out the major impacts of the current ecological crisis and insists on the way it is globally and drastically remodelling the Earth system.

Science live 2021 - Soil pollution

For the 30th edition of the Fête de la science, the ‘Science live’ event offered a daily appointment, from 1 to 10 October 2021.

In the 11 october programme ‘Anthropocene: a small footprint for a human, a big one for humankind’, Francis Garrido, Deputy Director of the Water, Environment, Processes and Analyses Directorate talks about a consequence of human activity, soil pollution, which is not well known to the general public. He details the various solutions developed by BRGM to diagnose and alleviate the various types of pollution. In particular, he discusses the role of the PRIME platform, an innovative facility dedicated to the analysis of environmental pollution and the means to remedy it.
