This expansion is creating social and environmental degradation at these frontiers and fostering socio-environmental conflicts. We review the concept of ‘commodity frontiers’ analyzing its roots through Jason Moore’s theory (2000) bringing concepts of World System theory and the Marxist concept of metabolic rift. We argue that this expansion occurs through the commodification of land, products and relations and explore the social and environmental impacts it causes and the conflicts it triggers. This paper is the introduction to the session of ‘Degrowth from the South’ as it sets the scenario for the responses and alternatives to this expansion that are analysed in the other papers. This paper is part of the forthcoming book Degrowth, vocabulary for a new paradigm.</p>1 aConde, Marta1 aWalter, Mariana  uhttps://degrowth.community/conference2014/science/content/commodity-frontiers-and-degrowth
