Following on from the Sustainable Food Student Convention (CEAD), supported by Erasmus+ in 2023/2024, and given the success of the project within the ecosystem, we decided to roll out this methodology locally for the 2024/2025 academic year, testing it in two pilot areas: Paris and Lyon. RESES wanted to promote and adapt its model of the Sustainable Food Student Convention (CEAD), deployed nationally and across Europe, by adding a strong local dimension: the Local Sustainable Food Student Conventions (CELAD) were born. The objectives were to bring together, equip, train, and strengthen the legitimacy of young people committed or wishing to commit to sustainable, healthy, and accessible food in their local area. Our ambition was to structure spaces for exchange, training, the provision of tools, and the building of coalitions of youth stakeholders capable of taking a stand on food issues at the local level. With this in mind, we wanted to: Unite student associations in two pilot areas, Paris and Lyon. Develop a program combining local and national issues to bring together youth stakeholders from the network committed to sustainable food. Structure coalitions of student associations working in synergy to influence local policies in favor of better access to sustainable, healthy, and affordable food for young people. Create spaces for dialogue between young people and local decision-makers. To address this, the Local Conventions' main objectives were to: Objective 1: Train and give tools to student associations, as well as the students who represent them, with experts and specialized associations on sustainable food issues and issues related to our food system (health, agriculture, environment, climate, biodiversity, inequality, etc.). Objective 2: To structure and unite student stakeholders in sustainable food in the Lyon and Île-de-France metropolitan areas. Objective 3: To be an exercise of participatory democracy, through collective intelligence methods and the co-construction of sustainable food projects with local stakeholders. Objective 4: To work on concrete proposals for local decision-makers, thus giving students a voice in the public debate on a fundamental issue. Student associations from the Lyon and Île-de-France regions therefore met during the 2024-2025 academic year with a common goal: to learn about sustainable food issues and to make their voices heard by decision-makers in their localities. These associations were trained by experts through a series of activities, including field visits, to encourage discussion, peer learning, meetings, and the exchange of diverse perspectives. The dual local and national programming enabled the associations and their representatives to enrich their experience through mutual assistance, peer-to-peer training, and the intersection of perspectives between the two regions. Following these meetings and training sessions, the CELADs resulted in concrete proposals aimed at opening a space for dialogue with local decision-makers. These conventions thus helped reposition students as key players in sustainable food at various levels, contributing to the ecological transition of food and agricultural systems. The diversity of experts involved offered a 360° view of local, national, and European dynamics. Furthermore, some webinars and testimonials—including those from Sustainable Food Student Convention students from 2 years ago—enabled participants to better understand the European level: EU mechanisms, the development of public policies, and the decisive role of citizens, all put into perspective with the local level and its expertise in agriculture and food. It also helped to grasp the concrete importance of the EU in the daily lives of people in the Member States.
