The book Les natures du productivisme: Une histoire environnementale de la France, de 1940 à nos jours by Renaud Bécot, Christophe Bonneuil, and Gabrielle Bouleau has won the 2026 Political Ecology Book Prize. Published in February by La Découverte, it is the third volume of a comprehensive environmental history of France, examining nearly a century of economic, social, and ecological transformations. The book was published on 26/02/2026 and contains 380 pages, priced at 24,000 €. Established in 2014 by the Foundation for Political Ecology (FEP), the Political Ecology Book Prize annually recognizes a French-language work that contributes, through its analysis, to deepen ecological thought, clarify environmental issues, or reflect on ecological transformations in society. The prize includes a stipend of 1000 €. The official award ceremony will take place on Saturday, October 3, from 18:00 to 19:00, at the Académie du Climat in Paris, as part of the 24th Festival of Ecology Books and Press. The book constitutes the third volume of Histoire environnementale de la France. The first two volumes covered the periods from 1780 to 1870 and from 1870 to 1940 respectively. This volume continues the investigation from World War II until today. The three authors examine how productivism—defined as an economic system focused on continuous growth—has shaped the French territory, its infrastructure, agriculture, energy consumption, and public policies. They specifically revisit the Vichy regime, reconstruction, and the "Thirty Glorious Years," France's dependence on colonial and post-colonial resources, the "petrolization" of French society, as well as the early resistances to pollution, dams, nuclear energy, and agricultural modernization. The investigation also focuses on the progressive emergence of the environment as a public action object: the appearance of environmental policies, the development of sustainable development and the "ecological transition," and the limitations encountered by these various devices. The book seeks to re-read contemporary French history through its material and environmental transformations. Renaud Bécot is an associate professor of contemporary history at Sciences Po Grenoble and a member of the Pacte laboratory. His work focuses on environmental history, labor, industrial pollution, and collective mobilizations against health and environmental risks. Christophe Bonneuil is a research director at CNRS and teaches environmental history at EHESS. A specialist in the relationships between science, nature, and societies, he is notably the co-author, with Jean-Baptiste Fressoz, of L'Événement anthropocène. Gabrielle Bouleau, an engineer and socio-political scientist at INRAE, is a researcher at LISIS. Her work particularly focuses on water policies, environmental indicators, and how ecological problems become—or do not become—public action objects. The 2026 jury of the Political Ecology Book Prize includes Céline Marty, a philosophy doctor and specialist of work in the work of André Gorz; Laure Pascarel, co-president of Éditions Utopia and manager of Librairie Utopia; Meixin Tambay, president of the Festival of Ecology Books and Press; Aristide Athanassiadis, a researcher specializing in the circulation of material flows, founder of the YouTube channel Metabolisms of Cities and co-director of Green Letter Club; and Alexis Vrignon, a historian and associate professor at the University of Orléans, co-author of Une histoire des luttes pour l'environnement and author of La Naissance de l'écologie politique en France. The trio succeeds Laurence Marty, the 2025 laureate for Apprendre et lutter au bord du monde, published by Empêcheurs de penser en rond – La Découverte. An anthropologist, feminist activist, and environmentalist, she discusses the formation of the climate justice movement around COP21 and the strategic questions that cross ecological mobilizations.
