Claire Lamine is a sociologist attached to the Ecodevelopment Unit of INRAE (National Research Institute for Agriculture, Food and the Environment) in France. His work, initially focused on the study of greening processes and models (a notion that refers to the increasing consideration of environmental issues in agricultural policies and practices) at the level of farmers and consumers, is now deployed at the scale of "agri-food" systems. On a "meso" scale, this work combines a systemic analysis of transition mechanisms and a pragmatist analysis of the visions and controversies at work around these transitions. Claire Lamine is also interested in emerging paradigms and narratives of greening and the ways in which the agricultural, food, environmental and health issues they propose are articulated, their possible translation into public policies, and the associated debates and controversies. During her career, she has developed numerous collaborations in Europe, the United States and Brazil. For example, she now coordinates the ATTER (Agroecological Transitions for TERritorial Food Systems) project.
