The lead partner is an environmental and nature conservation organisation that regularly works with young people through field programmes, awareness-raising activities and volunteer initiatives. Each year, the organisation involves a large number of secondary school students and young adults in practical environmental actions and non-formal learning activities. Based on these experiences, it has been observed that although young people are generally concerned about environmental issues, they often feel uncertain about how they can take concrete action at local level. Environmental problems are frequently discussed in global and abstract terms, while many young people lack specific knowledge about the natural values of their own surroundings and about biodiversity-related challenges in their communities. The organisation’s experience shows that there is strong motivation to act, but young people often lack the practical competences, tools and examples needed to turn environmental concerns into realistic local initiatives. This gap can lead to frustration or passivity instead of active engagement. Therefore, there is a clear need for learning opportunities that combine awareness with hands-on experience, practical skills and youth-led action. The immediate goal of the project is to actively involve groups of young people from four countries in protecting the unique natural heritage of the Carpathian Basin, while strengthening their knowledge, skills and confidence to act for biodiversity at local level. Beyond awareness-raising, the project aims to develop participants’ competences in observation, problem identification, action planning and community engagement. Through field activities, non-formal learning methods and digital documentation, young people will learn how to recognise local biodiversity challenges, analyse them and design small-scale environmental actions in their own communities. As an indirect objective, the project seeks to contribute to the improved protection of biodiversity in the partner regions by creating a multiplier effect: participants are expected to share their experiences, inspire their peers and remain involved in local environmental initiatives and organisations after the mobility. The project places strong emphasis on active participation and experiential learning, ensuring that young people are not only beneficiaries but co-creators of the process. The exchange is therefore designed not as a one-time event, but as the starting point of longer-term engagement, supported by digital tools, follow-up activities and local actions.
