The artist-designer collective Bureau d’études, created in 2000 by Xavier Fourt and Léonore Bonaccini, has developed different methods of mapping that have been produced, disseminated or put to work in the context of workshops in a dozen countries, in particular in France on the French agri-food system or on biocontrol. The collective has also implemented public action design approaches in the public space. It has also developed several design and popular education systems, particularly on endocrine disruptors. These approaches have notably taken the form of games.
