Stéphanie Barral is a sociologist at the French National Institute for Agronomic and Environmental Research (INRAE), with expertise in economic and political sociology. Her work focuses on the contemporary transformations of environmental and agricultural policies. Her first book (Capitalismes Agraires, Presses de Sciences Po, 2015) analyzes the growth of capitalist palm oil plantations in South East Asia despite social and environmental criticism. Her on-going research is driven by the following question: can we solve environmental problems with economic instruments? Related field work is about biodiversity offsets and payments for environmental services in France and the USA. More particularly she grasps 1) trade-offs between scientific knowledge, economic constraints and institutional normativity; 2) how economic instrument produce selection effects on the natural environment; 3) how these market-based policies are part of a larger a trend toward privatization in agricultural policies.
