Dossier No. 49- 2027/01: Frontiers, migrations, and decolonial experience in times of climate crises

In the first decades of the 21st century, the intensification of climate crises has profoundly reconfigured social, territorial, and political dynamics on a global scale. Extreme events, environmental degradation, forced displacements, and disputes over resources have become structuring elements of a scenario in which boundaries — geographical, symbolic, and epistemological — are continuously strained. In this context, the historiographical field is called upon to revisit its analytical categories, temporalities, and archives, incorporating perspectives capable of accounting for the complexity of these transformations. The dossier “Frontiers, Migrations, and Decolonial Experience in Times of Climate Crises” proposes to gather contributions that articulate history, environment, and human mobility, privileging critical and decolonial approaches. We are interested in understanding how different historical subjects — indigenous peoples, traditional communities, peripheral populations, migrants, and environmental refugees — have experienced, interpreted, and resisted multiple forms of crisis, often inscribed in colonial continuities and structural inequalities. From a scientific point of view, the dossier seeks to foster dialogue between environmental history, migration history, border studies, and Southern epistemologies, contributing to the theoretical-methodological strengthening of the field. Politically, this is an urgent agenda: thinking historically about climate crises implies recognizing unequal responsibilities, global asymmetries, and forms of violence that cross territories and bodies, while simultaneously highlighting practices of resistance, care, and re-existence. By emphasizing the decolonial dimension, the dossier invites the problematization of knowledge regimes that have historically silenced non-hegemonic experiences, proposing the valuation of other ways of narrating, knowing, and inhabiting the world. In this sense, the aim is not only to analyze historical processes but also to intervene critically in the modes of production of historical knowledge. Suggested thematic axes Contributions that dialogue with, but are not limited to, the following topics are welcome: History of migrations in contexts of environmental and climate crisis; Climate refugees and forced displacements: historical and comparative perspectives; Frontiers in transformation: mobilities, controls, and circulation regimes; Environmental history and global inequalities; Territories, socio-environmental conflicts, and disputes over resources; Indigenous and traditional experiences facing climate change; Local knowledge, cosmologies, and decolonial epistemologies; Memory, narrative, and testimony in contexts of crisis and displacement; Urbanization, peripheries, and socio-environmental vulnerability; Infrastructures, extractivism, and reconfiguration of frontiers; Gender, race, and intersectionalities in migratory and environmental experiences; Public history, audiovisual, and forms of communication about climate crises; Border universities and internationalization: practices, networks, and challenges in socio-environmental crisis scenarios. The dossier will accept original, unpublished articles resulting from completed or advanced research that demonstrate theoretical consistency, methodological rigor, and a relevant contribution to the historiographical field. Interdisciplinary and comparative approaches will be especially valued, as well as works that mobilize innovative sources and/or dialogue with historically marginalized communities and subjects.
