Relationships to time and space in a context of urban change: some findings from “space-time of action” analysis in Bogotá (1993-2009)

Abstract

International audience; Taking its inspiration from space-time prism formalized in time-geography (Hägerstrand, 1970) and using spatial analysis methods, the purpose of this study is to examine medium-term changes to household members’ access to place of activity, against the backdrop of urban change. To this end, the analytical framework uses the concept of “space-time of action” (Demoraes et al., 2018) referring to the combination of all the places of work or study that individuals go to, and the time taken to reach them. The analysis is based on two surveys conducted in Bogotá (Colombia) in 1993 and 2009, devised in the wake of work by the GRAB research initiative (Ined), to apprehend individuals’ spatial mobilities from a biographical perspective. Two groups at different stages in the life course and coresiding in the same households are more specifically looked at: schoolchildren and working adults. First, space-times of action are calculated and mapped using kernel outer rings for the two groups and the nine survey zones at the two dates. Second, the statistical significance of the discrepancies between space-times of action is assessed using a bivariate colocation test, hitherto used primarily in spatial epidemiology (Souris, Bichaud, 2011). The test indicates an overall stability in children’s access to school place and a more contrasting situation for adults. The presentation of the communication is available HERE.; Basándose en el prisma espacio-temporal formalizado en la time-geography (Hägerstrand, 1970) y utilizando métodos de análisis espacial, este estudio tiene por objeto examinar cómo ha evolucionado a medio plazo el acceso de los miembros de los hogares a su lugar de actividad en acorde con los cambios urbanos durante el mismo período. Para ello, el marco analítico utiliza el concepto de espacio-tiempo de acción (Demoraes et al., 2018) entendido como el conjunto de lugares donde las personas van a trabajar y estudiar y el tiempo que tardan en llegar allí diariamente. El análisis se basa en dos encuestas realizadas en Bogotá (Colombia) en 1993 y 2009, diseñadas en la línea del trabajo realizado por el GRAB (Ined), para aprehender las movilidades espaciales de los individuos desde una perspectiva biográfica. Se estudian más particularmente dos grupos en diferentes etapas del ciclo de vida y que co-residen dentro de los mismos hogares: los escolares y los adultos que trabajan. En un primer paso, se calculan y cartografían los espacios-tiempos de acción utilizando los límites exteriores de núcleos obtenidos mediante un alisado espacial para los dos grupos y las nueve áreas de estudio en ambas fechas. A continuación, se evalúa la significatividad estadística de las diferencias entre los espacio-tiempos de acción mediante una prueba de colocación bivariada, hasta ahora utilizada principalmente en epidemiología espacial (Souris, Bichaud, 2011). La prueba indica una estabilidad general en el acceso de los niños a la escuela y una situación más contrastada para los adultos. El soporte de la ponencia es disponible AQUI.; S'inspirant du prisme spatio-temporel formalisé dans la time-geography (Hägerstrand, 1970) et s'appuyant sur les méthodes d'analyse spatiale, cette étude a pour but d'examiner la façon dont l'accès des membres des ménages à leur lieu d'activité a évolué sur le moyen terme à l'aune des changements urbains survenus sur la même période. Pour ce faire, le cadre d'analyse utilise le concept d'espace-temps d'action (Demoraes et al., 2018) entendu comme l’ensemble des lieux de destination des individus pour le travail et les études, et le temps qu’ils mettent pour s’y rendre au quotidien. L'analyse repose sur deux enquêtes conduites à Bogotá (Colombie) en 1993 et 2009, conçues dans la lignée des travaux à l'initiative du GRAB (Ined), pour appréhender les mobilités spatiales des individus dans une perspective biographique. Deux groupes à des étapes différentes du cycle de vie et qui corésident au sein des mêmes ménages sont plus particulièrement étudiés : les écoliers et les adultes actifs. Dans un premier temps, les espaces-temps d'action sont calculés et cartographiés en gardant les limites extérieures de noyaux obtenus par lissage spatial pour les deux groupes et les neuf zones d'enquête aux deux dates. Ensuite, la significativité statistique des écarts entre les espaces-temps d'action est évaluée à l'aide d'un test de colocation bivarié, jusqu'alors utilisé principalement en épidémiologie spatiale (Souris, Bichaud, 2011). Le test indique une stabilité globale dans l'accès des enfants à l'école et une situation plus contrastée pour les adultes. Le diaporama de la communication est disponible ICI.
