Retour sur… / Une participation massive de l’UMR ESPACE à l’ECTQG 2023

11 membres de l’UMR ESPACE (donc 5 doctorants) ont participé du 14 au 17 septembre au colloque ECTQG (European Colloquium on Theoretical and Quantitative Geography) qui s’est déroulé à Braga (Portugal).

L’ECTQG est un colloque biannuel qui rassemble depuis 1978 la communauté scientifique travaillant au développement des méthodes quantitatives et de la théorisation en géographie.

Outre les présentations des travaux de l’unité, ESPACE a également organisé une session spéciale.

Uncovering Intra-Urban Spatial Patterns

Identifying, describing, and explaining the spatial structures of cities, especially in the perspective of linking them to particular externalities (in terms of economic performance, mobility, social functioning, etc.), has long been one of the main tasks of theoretical and quantitative geography. To achieve this, both deductive and inductive approaches are used. While there have been many empirical and modelling successes, revealing and understanding intra-urban spatial patterns remains a major challenge for several reasons:
– The quality and quantity of data to address certain issues may be insufficient. This has long been the case, for example, for land and property prices.
– The quality and quantity of data to address certain issues may be insufficient. This has long been the case, for example, for land and property prices.
– The problem may also be methodological. Methods and tools from spatial analysis sometimes struggle to deal with the complexity of the urban environment or to reveal multiscalar orders. In this respect, space syntax, morphometric analysis, and fractal geometry have recently been important innovations.
– The difficulty can also be explained by the increasing complexity of urban forms. From simple and compact forms with centre-periphery gradients, the early 21st century has seen them evolve towards vast forms with patchworks of built-up areas, natural zones, and agricultural spaces, where accessibility is often more important than geometric centrality. Revealing their orders requires tools to tackle complex objects composed, for example, of built/empty spaces and road networks.

Thus, at a time when new data are being produced and made available to researchers (user-generated data, data from sensors, or administrative registers), when new methods of analysis are being developed (machine learning, deep learning, multiscale modelling), revealing the underlying orders of urban structures still remains a challenge. Therefore, papers presented in this session could deal with the following topics:
– new data sources to reveal urban patterns which so far remained unknown
– new methods to deal with the complexity of urban patterns, especially in their multiscalar logics
– original couplings of new data and new methods to reveal intra-urban orders
– relevance of the newly found patterns for the understanding of the contemporary city – to what extent does the discovery of new spatial orders in the contemporary city raise questions about theoretical approaches hitherto taken for granted?
