We are happy to announce the IHOPE regional case study the Preservation, Decolonization and Sovereignty Reclamation at the Fort Apache and Theodore Roosevelt National Historic Landmark, Arizona. The Fort Apache project offers to IHOPE an important and unique case study in the rehabilitation and adaptive reuse of heritage—objects, buildings, places, and traditions—to serve pressing current needs. We envision operating at and contributing to environmental humanities and future studies, and possibly historical ecology as well. At Fort Apache our partnership is applying a blend of Apache traditional knowledge and sovereignty theory and practice to the management of an ecosystem that reflects and embeds a millennium of intense and highly varied cultural-biophysical linkages. The Apache traditional knowledge being revitalized at Fort Apache centers on highly personalized relationships with plants, animals, and landscape features as sources of individual and collective vitality. As a protected area within an increasingly urbanized and degraded landscape populated by people whose immediate forebears were fiercely independent hunter-gatherer-farmers, the Fort Apache property contains the symbolic, organizational, intellectual, and biophysical resources required for creating desired futures grounded in Apache pasts. The project has laid the essential foundations of equity, trust, and respect at the core of the IHOPE mission and has adopted and begun the decolonizing process of re-institutionalizing Apache ways of learning, planning, and doing in relation to the Fort Apache and T.R. property and the broader Apache community. In this sense, Fort Apache offers a good context for examining and applying transdisciplinary theory and management in a setting desperately in need of better ways of taking care of place and community.
