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

Abstract : 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 mid-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.
