Development or Ecocide? Sociotechnical Imaginaries and Contested Infrastructure in the “Tren Maya” Controversy

This article examines the controversy surrounding the Tren Maya railway megaproject in Mexico’s Yucatán Peninsula through the lens of sociotechnical imaginaries. We argue that the Tren Maya, much more than a technological intervention, came to embody differing visions of desired futures. Initially promoted by the Andrés Manuel López Obrador administration as a state-led reindustrialization program to mitigate social inequalities, the project was engulfed by the nationalist-developmental imaginary of the so-called “Fourth Transformation.” The local impacts that materialized in the construction process, however, sparked significant socio-environmental conflicts and mobilized a diverse opposition movement comprising indigenous communities, scientific experts, and environmental organizations. As the controversy unfolded, protest actors leveraged various legal mechanisms to challenge the epistemic and normative claims underpinning the government’s plans, eventually giving rise to a subversive imaginary that reframed the Tren Maya as a criminal, “ecocidal” enterprise. Our study reveals the intricate interdependencies between material and discursive processes in the (de)legitimization of competing infrastructural imaginaries and their role in mobilizing social forces. In particular, we underscore the crucial yet often overlooked role of legal channels and institutions in generating, validating, and amplifying imagined futures. By illustrating how social relations and normative ideals are co-produced with technoscientific knowledge and material facts, this research contributes to a more nuanced understanding of how different sociotechnical imaginaries interact, compete, and gain traction in the context of infrastructural transformations.
