Set in Patagonia’s Bahía San Antonio–the coastal system of Las Grutas, San Antonio Oeste, and San Antonio Este in Rio Negro, Argentina–this project-based seminar investigates how an energy-and-logistics boom can be reimagined as a platform for long-term regional development. As the bay emerges as the Atlantic gateway for exports from Vaca Muerta, the world’s second-largest shale gas reserve, students will consider whether and how local capacities might endure beyond the boom. How can productive diversification strengthen long-term sustainability? Combining spatial analysis, policy design, and research-based writing, students will explore strategies that can improve quality of life and meet local expectations. In order to produce an integrated territorial diagnosis that weaves together social, economic, environmental, and institutional dimensions, students will build projects through critical readings, comparative case studies, and mapping exercises. The seminar approaches the bay both as a productive landscape and as a social system in transition, working with public officials, scholars, and local actors students to chart the institutional and spatial ecology of the region. Beyond identifying land-use and expansion scenarios, priority investments and infrastructure, and governance arrangements capable of sustaining benefits beyond the energy cycle, student projects will lay the groundwork for a digital publication synthesizing the seminar’s outcome by combining maps, visual narratives, and concise analytical essays into a coherent whole. The seminar aims to deliver both a diagnostic portrait of Patagonia’s Atlantic frontier and a design framework for its sustainable future.
