We currently face a baffling paradox. While since the fall of the Berlin Wall in 1989 a seemingly inexorable process of globalisation has been foreshadowing a peaceful and frontierless world, the number of walls across the world has been rising at a steady pace. Liberal and open societies buttressed by trade, international law and technological progress were supposed to implacably contribute to the erosion of frontiers and walls between nations. However, in a context of surging populist discourses, securitarian anxieties and identitarian politics as well as concomitant flows of migration alimented by climate change, conflict and poverty, nations have recently started to barricade themselves behind new walls.

Has globalisation reached its apex after centuries of growth as suggested by the latest figures of the WTO? In the affirmative, does this imply that we are ushering into a new era of degrowth? Or are we witnessing the reorganisation of the very architecture of globalisation, which remains based on the twin logic of the acceleration and continuous increase of the volume of exchanges, as well as the steady densification of geographic connectedness. Are global exchanges restructuring concomitantly to the fourth technological revolution and the expansion of the digital economy? The present Dossier proposes to approach this question by observing the nature and the evolution of the principal flows that characterize globalisation.
