Mobility in the Face of Extreme Hydrometeorological Events 1: Defining the Relevant Scales of Analysis

With climate change, flash floods are multiplying and intensifying in various regions of the world and especially in the Mediterranean. Motorists are particularly vulnerable to these violent and difficult to predict events. Thus, half of the flood victims concern people surprised by their daily mobility, going to work or going to pick up their children at school. There is therefore a challenge to better understand how population movements are exposed to these phenomena. The aim of this book is to first provide a summary of the interdisciplinary work done over the past ten years on the exposure of daily mobility. This cannot be done without taking into consideration how these mobilities have evolved with the reorganization of spaces over long time. Residential mobility, the way in which the occupation of the flood zones evolves with time and the resulting immobile exposure are thus also at the heart of this work. In the face of recrudescence and the intensification of fast floods, we seek to understand how the interaction of hydro-meteorological, social and development dynamics combine to bring about an improvement or, on the contrary, a worsening of both mobile and immobile exposure. One of our hypotheses is that each event constitutes a more or less significant trigger of adaptation actions at different scales. We rely on different fields and studies conducted in the South East of France and more broadly on the Mediterranean basin to answer these questions and verify these hypotheses.
