Support for the development of an international environment at Jan Evangelista Purkyně University in Ústí nad Labem (hereinafter referred to as UJEP) is part of all strategic documents in the field of internationalization. One of the most important tools of internationalization is international mobility, which is implemented within this project in cooperation with the Lebanese International University (hereinafter referred to as LIU), whose strategic goals include the development of capacities for working people through cooperation with international academic institutions. The aim of the project was to contribute to the mutual exchange of experience in education, with a focus on project-based and research-oriented teaching in environmental sciences through the implementation of 12 mobilities. UJEP received a grant of EUR 38,284 for the implementation and organization of these mobilities. A prerequisite for the implementation of the mobilities was compliance with all the principles of mobility in the Erasmus+ program, including, for example, the organization of transparent selection procedures ensuring equal access and non-discrimination, the implementation of mobility based on pre-signed agreements, recognition of results, etc.
