is a sociologist and urban planner. He is a senior CNRS researcher at the CRESSON research laboratory (France) and scientific coordinator of the International Ambiances Network (ambiances.net). His research focuses on the theory of urban ambiances, everyday perception in the urban environment, sensory culture and the ethnography of public spaces.
La mobilité ne constitue pas seulement un des enjeux majeurs des espaces publics urbains, elle se donne comme un des critères essentiels conférant à l'espace urbain son caractère public. C'est ainsi que le lieu-mouvement peut être considéré comme l'idéal-type de l'espace public contemporain. Réduit parfois à un complexe d'interconnexion de différents modes de transport, le lieu-mouvement relève plus fondamentalement d'un espace de ressources et d'épreuves mobilisant l'activité perceptive et motrice des passants. A cet égard, on peut s'intéresser à l'"informationvoyageur" en mettant à l'épreuve les conditions de production, diffusion et réception des informations mises à disposition des voyageurs (Gare du Nord : Mode d'emploi, 1994). Il s'agit de tester la manière dont un site favorise le transit en délivrant des messages pertinents et en proposant des équipements adéquats. L'analyse du dispositif informationnel-annonce sonore, télépancartage, signalétique, cellule d'information, etc.-révèle alors le lien étroit qui se tisse entre l'espace de circulation et l'espace de communication.
In 2015 a group of Brazilian and French researchers carried out a field investigation at the Condominío Barão de Mauá. 1 The condominium is located in the town of Mauá, some 30 kilometres from São Paulo, Brazil. The complex, built in 1996, consists of 54 buildings housing about 7,000 people and stands on land contaminated by industrial waste buried there. The residents became aware of the contamination in April 2000 when an explosion occurred during maintenance work on one of the pumps for the condominium's underground water reservoirs. It was probably caused by the presence of methane gas. A worker was killed in the explosion, another one badly burned. Legal proceedings have been underway ever since, leaving the residents exposed to the risk of contamination by carcinogenic substances and another explosion.1 This research is part of a dual framework: a CNRS program PEPS FaiDoRA "Faibles Doses, Risques, Alertes" (CRESSON-UMR AAU, France) and a FAPESP program "Da Cominicação de Riscos à Cultura de Risco" (CETESB, Brazil). The research team was composed of
