## Description
**Ce projet est issu des travaux des élèves du Master Urban Governance, Policy and Planning, spécialité Governing Ecological Transitions in Cities (GETIC) de 2024-2025 :**  
  
PRÉFACE de Pauline Gleizes, tutrice  
  
This project is the result of a collaboration between the Observatoire de l’Immobilier Durable, who was looking for new indicators for the cost of action and inaction when it comes to adapting buildings to climate change, and a group of five students from the GETIC master.  
  
The students’ choice of focusing on floods was particularly relevant since major floods had recently been happening in France and throughout Europe. Additionally since the birth of the Cat-Nat insurance system, a significant part of the economic costs of natural disasters in France have been identified as related to floods.  
  
The findings show that the limits of our French natural-disaster coverage system might soon be reached, and these alarming results are essential to inform public policymakers. Beyond demonstrating that adapting buildings to climate change is beneficial, the students have found that the multi-stakeholders governance around water management and flood-risk management could be made more coherent in order to deliver more efficient crisis responses. Furthermore, they have found that insurance companies should be differently involved in this environment. These recommendations are more relevant than ever, as we experience fast-paced urbanization and climate change, thus increasing risks of floods.
