The application for this project was linked to the project for the previous academic year, 2020-2021. In our autonomous community (Basque Country), on the recommendation of the Basque Government, no mobility was carried out due to the COVID-19 pandemic. This meant that a large number of mobility grants were postponed for the following years. That is why we only asked for 3 grants (2 for students and one for staff). The aim of the present project, therefore, was to complement the grants from previous projects and thus to continue participating in this wonderful programme.
