The H2020 SMARTDEST project “Cities as mobility hubs: tackling social exclusion through ‘smart’ citizen engagement” investigates the processes through which new forms of mobilities (such as tourism and mobile dwelling) reproduce new forms of social exclusion, imbalances, conflicts, and other ambivalent externalities in urban contexts. The 2nd Scientific Workshop involves leading experts in the field to present their own research projects and to discuss project’s preliminary results.
