Drawing on traditions of cultural geography and creativity, the environmental humanities, and critical geographic theory, this dissertation includes five articles that develop geopoetics as a sub-field of the geohumanities. It sketches the contours of three modes of geopoetics: as creative geography, as literary geography, and as geophilosophy. Through site-based projects at three Sonoran Desert ecological research and tourism sites, it furthers the use of artistic and literary practice in geohumanities research, employs that practice to interrogate climate change and Anthropocene narratives, and addresses the role of art and literature in environmental issues. In addition, it utilizes the development and teaching of a community course on climate change and poetry as an additional "site" of research, to illustrate the role of arts and humanities approaches to global environmental change. Drawing on the content of the climate change and poetry course, it also includes a close reading of the work of five contemporary Indigenous ecopoets in relation to climate narratives. This dissertation proposes that geopoetics, literally "earth-making," is broadly relevant to questions of socio-ecological futures and is a means to imagine and enact other ways of inhabiting the world.
