Ensayos is a collective research practice initiated on the archipelago of Tierra del Fuego in 2010. Ensayos’ issue-based research methodologies arise from archipelagic delirium and are characterized by their sensuality and precariousness. Drawing on the existing conservation initiatives in Tierra del Fuego (WCS Parque Karukinka, Caleta Maria, and the Selk’nam Corporation Covadonga Ona), Ensayos insists on experimental practices that entangle artistic and social science methods with the environmental research efforts already underway. Though Ensayos first focused solely on the ecopolitical issues impacting the Fuegian archipelago and its inhabitants –past and present, human and nonhuman– now, other archipelagos have come into view (Norway, Australia, New York, and Sri Lanka). Ensayos (inquiries or rehearsals in English) is a global exercise in emergent forms of eco-cultural ethics.
