Conférence publique de Jean Viard (gratuite)
S'appuyant sur plus de 30 ans de recherche et d'écriture, le sociologue Jean Viard partage les idées développées dans son dernier ouvrage, L'individu écologique : naissance d'une civilisation.
Il propose une analyse lucide et engagée des profondes transformations sociales et culturelles qui remodèlent notre monde.
Du déclin des idéologies de l'ère industrielle à l'émergence d'individus interconnectés mais fragmentés à l'ère numérique, Jean Viard explore comment le changement climatique est devenu la force déterminante de notre histoire commune.
Cette conférence nous invite à imaginer une nouvelle civilisation, où « l'individu écologique » redéfinit nos relations les uns avec les autres, avec la vie et avec une planète profondément transformée.

Guiding Landscapes
Landscape architects play a key role in adapting cities to climate change at a variety of scales. Planning, conceiving, and managing new resilient urban districts, reorganizing the public realm by reopening soils, increasing rainwater infiltration, and developing urban biodiversity to cool cities are all essential challenges.
Understanding soil and its conditions is the first step in assessing a location’s potential for ecological and sustainable projects. This will be one of the key aspects we explore during our visits to Nantes.
Nantes has undergone significant urban transformations that have gained international recognition. One notable example is the “Plan Guide” for Ile de Nantes, an experimental landscape urbanism project that initiated discussions about the role of our profession in urban planning.
Numerous landscape architects have worked in France and in the Nantes region and are excited to share their experiences with you.
