Introduction
The event, organized at the CPDA in Rio by UFRRJ, INRAE, UFRGS and ASPTA (all participants of the ATTER network) with the participation of ANA (National Articulation of Agroecology) and the Foundation Oswaldo Cruz (Fiocruz), benefited from the support of the ATTER project and also from the contribution of the Brazilian research agencies CAPES and CNPq.

The workshop was structured into two sessions, one on public policies and the other on collective action. In the first, the French experience of the policy of “Territorial Food Projects” as well as its variations in Ardèche, one of the study territories of our projects, were presented by G. Maréchal, C. Lamine and K. Nunes, and the Brazilian experiences of the cities of Curitiba and Belo Horizonte were reported by C. Grisa and D. Adil. In the second, Brazilian and French initiatives around the reconnection between agroecology, food and health were presented by H. Lopes, L. Soares, A. Freire, M. Jenatton and C. Lamine, with the aim of boosting cross-learning effects and translocal debates. Throughout the day, the debates, led by C. Schmitt, R. Maluf, P. Niederle and A. Brandenburg, made it possible to discuss numerous questions, particularly around the territorial scale, the place of greening in transitions, and the effects of crises and political ruptures.
