Pablo Martínez, co-founder of 300.000 km/s, and Sergio García, both editors of the journal ZARCH, will moderate a roundtable with some of the contributors to the journal on the 25th February at 12 pm, at COAC in Barcelona. Today, different research groups are exploring the use of data and methodologies to build models from which to describe, discover, predict or simulate urban phenomena as if they were laboratories of reality. This description is key at a time when we must reorder cities to meet the challenge of climate adaptation. A radical change that also has consequences for social justice, health and care, emerging economies and new mechanisms for participation. Knowledge that, for the first time, is capable of being reproducible worldwide. All these reflections are the starting point for the latest issue of the journal ZARCH (published by the University of Zaragoza) which, under the title Forma y comportamiento: modelar la urbanidad, reflects on this paradigm shift and the challenges it poses. In this session, the content of the magazine will be presented in the form of a round table with some of the authors of the articles, such as Maria Buhigas, Pau Solà-Morales and Esteban Moro.
