Carlos Tornel is a researcher and writer based in Mexico whose work sits at the intersection of political ecology, critical geography, and territorial struggles. His research focuses on contemporary forms of coloniality, capitalism, and extractivism, as well as the disputes that shape so-called “energy transitions”—from the expansion of fossil fuel infrastructures and the mining boom tied to “green” technologies, to the processes of militarization, dispossession, and territorial reconfiguration associated with megaprojects and logistics corridors. Engaging decolonial and critical perspectives—including debates on autonomy, subsistence, justice, and the pluriverse—his work challenges liberal-modern frameworks that tend to reduce the socio-ecological crisis to questions of management, efficiency, or “good governance,” and instead foregrounds its historical and structural roots. Alongside academic writing, he participates in networks and collective processes aimed at strengthening territorial alternatives and practices of mutual support, combining theoretical reflection, editorial work, and the production of communication materials. Through spaces such as the Global Tapestry of Alternatives and the Southern Ecosocial and Intercultural Pact, he advances South–South exchanges and projects dedicated to disseminating and systematizing concepts and experiences, with a particular emphasis on radical alternatives, pluriversal territorialities, and critiques of the myth of progress. His trajectory brings together scholarly work and public-facing essays, sustained by a commitment to making conflicts visible, holding open horizons of autonomy, and imagining transitions that do not reproduce new forms of dependency and socio-ecological sacrifice.
