The main aim of these two seminars is to develop key and cross-disciplinary skills (knowledge, know-how and professional skills) and to work towards the inclusion of 86 youth workers and people with fewer opportunities, by raising awareness of issues and concepts that are new to them: the Social Solidarity Economy (SSE), and Low Technologies (LT). The aim is to boost the employability of young people, raise their awareness of climate issues, introduce them to the opportunities offered by the Erasmus+ program, and ultimately turn them into multipliers in their realities. They took place respectively from August 1 to 10, 2023 (SSE); and from July 8 to 17, 2024 (LT). Such a project responds to the lack of knowledge about SSE and LT, and the need to develop environmentally-friendly projects within these two practices. The two seminars thus explored the link between these various elements: SSE and LT are conceived as means of integrating young people (JAMO and NEETs), and disadvantaged publics, while supporting an ecologically responsible model. The context of these two seminars is therefore the desire to raise awareness of climate issues, by presenting new production and consumption models with a high degree of replicability in all contexts of the Euro-Mediterranean zone and the Caucasus. The SSE is a subject of interest in that it represents a reality of the first order: 19.1 million jobs in the European Union, i.e. 9% of the working population, 10% of the wealth produced and 26% of the businesses created in Europe. In this respect, it is the subject of an Action Plan for the Social Economy, initiated by the European Commission, the aim of which is to stimulate this sector not only through subsidies, but also by developing a favorable and incentive-based political and legal framework, enabling the integration of involved youth workers. Low Technologies, for their part, involve 5 million jobs and over 1,000 implementation projects throughout Europe. They are an integral part of the objectives set by the European Green Deal and national ecological transition plans, and represent an original and responsible way of producing and consuming. As noted by researcher D. Bourg, Low Technologies are characterized by their high degree of replicability (Bourg, 2020). Thus, via this project, AMSED and its partners aimed to develop the key and transversal skills of 86 youth workers, NEETs or people from refugee backgrounds, youth leaders in setting up non-formal education youth initiatives and projects linked to SSE and LT, improving their personal and professional development, their participation in society as active citizens, promoting their employability on the labor market resulting from this new model; the participants involved were thus able to become multiplier actors in their context. The project's specific objectives and pedagogical pathway are as follows: (1) Stimulate understanding of the concepts of sustainable development, SSE, Low Technologies (LT), global warming, youth employability, carbon emissions, Green Deal ecological footprint, green entrepreneurship, eco-citizenship, disadvantaged youth workers, employability, start-ups; (2) Analyze the needs of youth workers. (3) Share experiences and best practices related to SSE and LT to strengthen the inclusion of disadvantaged young people; (4) Multiply synergies between different actors (young people, civil society, local authorities, elected representatives, decision-makers, companies, media) to identify employment potential in the social and solidarity economy; (5) Capitalize and create tangible tools (creation of innovative projects, recommendations, project financing tutorials, risk analysis) with a multiplier effect; (6) Establish partnerships to promote the SSE and Low Tech; (7) Present Erasmus programs, mobility programs and their financing, and participate in their dissemination. This project was in line with Erasmus+ objectives, aiming to improve skills and raise awareness among youth workers, NEETs, refugees and people with less experience of SSE, LT, the fight against global warming, sustainable development, climate issues and European programs. Through this project, AMSED and its partners have developed the key and transversal skills of 86 disadvantaged youth workers and youth leaders.
