Climate change impact, adaptation and associated costs for coastal risks in France

As part of the French climate plan, an inter-ministerial working group called “climate change impacts, adaptations, and associated costs in France” was created to evaluate potential damages caused by climate change and to identify possible mitigation measures. Seven thematic committees were organised, including the “natural risks, insurance and adaptation to climate change” committee, within which the coastal risks working group focused on the impacts of erosion and coastal inundation. This paper presents the methodology, results, and recommendation of this working group. A risk estimation methodology - where risk is considered as a combination of hazard and the vulnerability of the exposed assets – was developed at a regional scale for LanguedocRoussillon in 2100. Sea level rise and hazard evolution scenarios were used to estimate the costs of damages to exposed assets. The results serve as a rough estimate of the direct and indirect tangible costs potentially induced by coastal erosion and inundation in the 21st century. This paper discusses the results, addressing the uncertainties in each step of the assessment, specifically identifying the factors that were not taken into account and the limitations of the data sets. Finally, recommendations of adaptation measures, spatial planning, and short-term risk management were produced

Analyse multicritères : application aux mesures de prévention des inondations. Guide méthodologique.

La décision de mettre en oeuvre des mesures de prévention des inondations doit être précédée d'une évaluation des mesures projetées. Cette évaluation doit permettre d'établir la pertinence, la faisabilité, l'efficacité et l'efficience du programme de mesures. L'analyse multicritères fait partie des outils d'évaluation disponibles pour juger du bien-fondé des mesures de prévention proposées par un maître d'ouvrage. Ce dispositif d'aide à la décision, appliqué de manière systématique pour les projets importants, permet de comparer les mesures entre elles à l'échelle du territoire national et de faire un choix entre plusieurs options de mesures sur un même territoire. L'attribution éventuelle de fonds publics peut reposer ainsi sur une base méthodologique commune et objective

Science and technology research and development in support to ITER and the Broader Approach at CEA

In parallel to the direct contribution to the procurement phase of ITER and Broader Approach, CEA has initiated research & development programmes, accompanied by experiments together with a significant modelling effort, aimed at ensuring robust operation, plasma performance, as well as mitigating the risks of the procurement phase. This overview reports the latest progress in both fusion science and technology including many areas, namely the mitigation of superconducting magnet quenches, disruption-generated runaway electrons, edge-localized modes (ELMs), the development of imaging surveillance, and heating and current drive systems for steady-state operation. The WEST (W Environment for Steady-state Tokamaks) project, turning Tore Supra into an actively cooled W-divertor platform open to the ITER partners and industries, is presented
