Marta Vallvé @martavallve.bsky.social · 30/12/2025Departing from this, I propose to identify the social and natural aspects of the rift, their interrelation, and their link to capital accumulation to understand the material roots of any particular socio-ecological conflict. 010 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025Those separations in the social terrain create the setting for the disruption of natural cycles, generating ecological conflicts. So, bingo! This view connected social contradictions with natural degradation and could be useful to study the link between social conflicts and ecological issues. 100 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025Therefore, I could see that when Marx talks about a rift in social metabolism, he is referring to a separation in the social terrain. A separation between production and consumption, between labour products and human needs, between humans and their conditions of reproduction. 100 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025After analysing all Marx's passages on metabolism, I realised that he doesn't use the term "social metabolism" as a synonym for the metabolic interaction between humans and nature, but to refer to the internal metabolism in society, by which the products of labour reach human needs (circulation). 200 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025What was common between Foster and that literature on ecological distribution conflicts was their understanding of social metabolism as flows of energy and materials. Foster (and many others) attribute this definition to Marx, but I couldn't find the passage where Marx said that. 100 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025Being a fan of J. B. Foster, I thought using a metabolic rift approach to analyse the material bases of socio-ecological conflicts would be pertinent. As a Marxist approach, it is inherently historical and links social contradictions and ecological degradation to capital accumulation. 100 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025I thought it was a great idea to use a metabolic approach to study socio-ecological conflicts, but I also thought: sure, more mining will generate more conflicts around mining, but I would like to be able to say something more. Why does mining increase? Why is this mining conflictive? 100 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025Then, I came across this literature on ecological distribution conflicts that studies how increases or changes in social metabolism (defined as flows of energy and materials) generate social conflicts around ecological issues (e.g. the more mining, the more social conflicts around mining). 100 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025I had also learned that ecological problems appear when this metabolic interaction between humans and their environments enters into contradiction with natural cycles (e.g., displacing the nutrients of the soil or disrupting the hydric cycle by taking too much water fast). That is a metabolic rift. 100 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025I had learned from Marxist ecology literature that, just as organisms or cells, societies have a metabolism with their environments, without which they cannot live. They take raw materials and energy, transform nature, and leave waste in the process of producing goods to cover human needs. 100 0
Marta Vallvé @martavallve.bsky.social · 30/12/2025In my thesis, I analyse social conflicts and divides around green policies, but before doing a case study, I wanted to reflect on the theoretical approach and research strategy to analyse those conflicts and divides. This article is the outcome of this reflection. 100 0

Marta Vallvé @martavallve.bsky.social · 22/12/2025De totes formes, hem trobat que la diferència en el suport a polítiques verdes entre zones rurals i urbanes a Espanya és molt petita. Possiblement, aquest no és un tema tan central de divisió política territorial com pot ser en altres països. 010 0
Marta Vallvé @martavallve.bsky.social · 22/12/2025Tanmateix, només les percepcions de perjudici expliquen part de la bretxa rural-urbana en el suport a les polítiques verdes, suggerint que la major oposició rural està relacionada amb una major percepció de perjudici i no amb una menor priorització del medi ambient respecte a qüestions econòmiques. 100 0
Marta Vallvé @martavallve.bsky.social · 22/12/2025Els nostres resultats mostren que tant els valors postmaterials i la priorització del medi ambient per sobre del creixement econòmic, per una banda, com la percepció de perjudici de les polítiques verdes, per l'altra, estan relacionats amb el suport. 100 0
Marta Vallvé @martavallve.bsky.social · 22/12/2025L'oposició a les polítiques verdes també s'ha relacionat amb el repartiment dels seus costos, que sovint afecten especialment les zones rurals. (Per cert, sobre la transició energètica en zones rurals del sud de Catalunya recomano el llibre "Molinos y gigantes", de Jaume Franquesa). 100 0
Marta Vallvé @martavallve.bsky.social · 22/12/2025El suport a les polítiques verdes s'ha relacionat amb els valors postmaterials, així com l'oposició a elles s'ha relacionat amb la priorització d'objectius materials (econòmics, de seguretat, etc.) per sobre d'objectius postmaterials com la protecció al medi ambient o la llibertat d'expressió. 100 0

Marta Vallvé @martavallve.bsky.social · 17/12/2025It's also amazing to realise that a metabolic perspective not only helps us better understand the sources of our ecological problems today, but also the emergence of life in the first place in a universe seeking to increase entropy. 131 0
Marta Vallvé @martavallve.bsky.social · 17/12/2025In The Story of CO2 is the Story of Everything, we learn that CO2 is both the source of the main element of life (carbon) and mediates the relationship between virtually the only source of energy for the biosphere (the Sun) and the Earth, regulating the climate. 121 0
Marta Vallvé @martavallve.bsky.social · 17/12/2025Interestingly, we also see that, as with human history, the evolution of life is not linear but rather dialectic, contradictory, discontinuous. Life innovations can enter into contradiction with existing life forms, provoking crises, but might set the ground for further opportunities for life. 121 0
