María, thank you! It has been so nice and fun to share not only the working space with you but so much more! ♥️

Thank you so much, Rubén! I'm looking forward to seeing your amazing work presented in your defence very soon! ♥️

Having officially finished my PhD, I can say that one of the best things of this journey was being part of the @dec-gr.bsky.social. Thank you so much for everything!

Presentació de tesi Tesi

Aquest divendres a les 11h defenso la meva tesi doctoral a la UAB: www.uab.cat/ca/escola-do...

It has been great to navigate this paper with amazing @gefjonoff.bsky.social . Started expecting angry right-wing men to feel threatened by feminism and found out more than one surprise 👇

Algunas reflexiones sobre la fotovoltaica en tejados.

A finales de 2025, la fotovoltaica conectada a red en el estado español generó 50 TWh y el autoconsumo 10 TWh.

Algunos estudios recientes estiman el potencial de generación en tejados. Veamos los resultados y algunas conclusiones políticas ⤵️

La brecha de renta entre caseros e inquilinos es brutal.

El mercado del alquiler está destrozando nuestra sociedad: redistribuye renta de quienes menos tienen hacia quienes más riqueza concentran, cada vez en mayor medida.

El alquiler es una fábrica de desigualdad.

Los últimos once años han sido los once años más calurosos a nivel global - Climática, el medio especializado en clima y biodiversidad El promedio del trienio 2023-2025 supera los 1,5 ºC de calentamiento global, consolidando una tendencia inequívoca impulsada por la acción humana.

🌡️ Los últimos 11 años han sido los 11 más cálidos desde que existen registros

Por primera vez, la temperatura media global ha superado los +1,5 ºC en promedio durante tres años consecutivos respecto al periodo preindustrial.

Green policies can be contentious, with opposition often highlighting rural-urban divides. In this article we measure and analyse the perceptions of harm associated with several green policies (renewables, motor fuel taxes, car restrictions, conservation restrictions, and pesticide and antibiotics bans). We conceptualize these perceptions of harm as an individual dimension of the environmental justice paradigm, closely related to support for green policies and its characteristic rural-urban gap. Using survey data from Spain, our findings reveal that perceptions of harm, together with postmaterialist values and environmental prioritization, are associated with support for green policies. However, only differences in perceptions of harm account for the rural-urban gap, which is modest in size and remains partly unexplained. Our findings suggest that rural dwellers are not less supportive of green policies because they have weaker postmaterialist values or prioritize the environment less, but because they feel they are the losers of ecological transitions.

New article!

Departing 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.

Those 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.

Therefore, 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.

After 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).

What 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.

Being 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.

I 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?

Then, 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).

I 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.

I 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.

In 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.

New publication! I wrote a conceptual paper reflecting on how to study the material roots of socio-ecological conflicts using a metabolic rift approach. This is the story of how this paper came to be 🧵 doi.org/10.1177/0486...

També les emissions de CO2 segueixen creixent. No pot venir de sorpresa que, segons l'Emission Gap Report de 2025 (UNEP), virtualment ja no es pugui evitar una pujada de 1,5 ºC per sobre els nivells preindustrials. www.unep.org/resources/em...

El gràfic de l'evolució de les proporcions pot ser enganyós, ja que semblaria que les renovables pugen perquè els combustibles fòssils i la nuclear baixen. En realitat, els combustibles fòssils segueixen pujant i les renovables s'afegeixen a un mix energètic creixent.

És cert que les renovables ja produeixen el 30% de l'electricitat mundial, tot i que només el 14,82% de l'energia primària. Però més important que això... 👇

The European Union Is Turning Away From the Green Transition Europe has often called itself a global leader in fighting climate change, even promising to halt the sale of new gas-powered cars by 2035. Yet now it’s dropped the plan, as part of a broader retreat from the green transition.
