What underpins these relations, practices, and experiences of being apart and yet together? Based on a long-term multi-sited fieldwork carried out in Spain and Bolivia from 2013 to 2015, this study sets out to address these questions by investigating caring practices, mediated connections, (non)material exchanges, and lived experiences of “doing” and “feeling” family across borders. It conveys the story of ten families divided between Madrid and the Bolivian urban areas of Cochabamba, Sucre, and Santa Cruz de la Sierra. READ MORE

The analysis involves the exploring of how migrants strive to prepare, manage and survive the multiple risks and structural barriers they encounter: the exits from Eritrea and Ethiopia, negotiations and contacts with various brokers and facilitators, organized crime and violence, restrictive border controls, passage through the Desert and high Sea and finally, ‘managing the asylum system in Sweden’.
