The very first gathering of Grounded Urban Practices happened in Amsterdam in the first days of March 2019. As GUPs from Amsterdam and Rotterdam had never met before, it was decided to bring them together before they would travel to Cairo to meet their Egyptian counterparts. During the encounter the participating GUPs reflected on the research as it was conducted in Amsterdam / Rotterdam so far, including the framework, definition and tentative outcomes. The encounter also functioned as a preparation for the upcoming trip to Cairo, and what it would mean to share the local knowledge and experience of GUPs in Amsterdam and Rotterdam with their counterparts abroad.
