Methanation Units Development in Brittany: Conceptualizing the links between Food Security, Climate Change and EnergyTransition in the Anthropocene 


As biogas has been strongly developed in Brittany, attention has been paid by the sociology of mobilization to the potential nuisances it could have on the population – a key factor to explain the local oppositions to the projects of methanation units. As Climate Change deepens the problem of water supplies for agriculture, this communication analyzes the link between the international political economy of Britain intensive breeding, methanation units development, and the Anthropocene dynamics. As it will be argued, the “green” biogas appears to reproduce the destructive dynamics of the Anthropocene, as it provides intensive farming with a concrete and material argument for its reproduction. In a nutshell, we offer to stress the political dimension of methanation units massive development under the Anthropocene regime of historicity. 

Key words : methanation units; Anthropocene; Climate Change; Biodiversity; Intensive Farming
