Riverine borders are not “natural” borders dividing up space – certainly not for the people who have called these fluid borderlands their home for years, decades, or even centuries. One example is the Oyapock River, the official border between Brazil and France, which is a one-way street. In the lecture, Fabio Santos goes into ethnographic details of the river border and contributes to conversations across national borders. The lecture will take place online via Zoom on the 22nd of March, 4:30 - 6:00 pm. A registration is required. The lecture is aimed at citizens, students and researchers.
