The Warsaw University of Life Sciences implemented a project under the Erasmus+ Programme, Key Action 1: “Mobility of students and staff in higher education institutions,” within the framework of cooperation between programme countries.The 26-month project included all forms of mobility provided for in the programme. The initiative aimed to promote the internationalisation of Warsaw University of Life Sciences and its partner universities by encouraging international mobility among students, academic staff and administrative personnel, facilitating the exchange of scientific and research ideas, and sharing experiences, best practices and modern technologies. The project also focused on building and strengthening lasting partnerships and cooperation networks, as well as the European University UNIgreen, which will serve as a foundation for future international initiatives. The implementation of these activities has enhanced the prestige and international standing of Warsaw University of Life Sciences. The project's ultimate goal was to foster a dynamic educational, research and administrative environment that values and leverages cultural and intellectual diversity to achieve shared academic and scientific objectives.
