This youth exchange was a continuation of the one carried out in 2022. Our Spanish partner had welcomed 20 young people and 2 leaders during the summer for an exchange on the theme of the environment and sustainable development. For our organization, this was the first experience of organizing and hosting an Erasmus+ youth exchange. We had 4 objectives: * Promote the richness of the Vercors through the natural environment, the Human life on this territory and good sustainable practices. * Promote mountain-related professions and adaptation to the constraints of the living environment. * Share good environmental practices between young Spanish and French people. * Raise awareness of environmental issues and promote sustainable practices. In addition to the specific objectives of this exchange, we also wanted to make a success of our first experience of organizing a youth exchange as a host organization.
