Book excerpt: This book includes revised dissertation chapters from the author’s (second) PhD, which was awarded in 2020 by Murdoch University, Australia. It also includes three chapters summarising recent developments. This was an innovative, transdisciplinary, research project, using phenomenology as the over-arching meta-paradigm. The investigation involved collaborations and literature reviews across numerous disciplines, including philosophy, geography, ethnoecology, sociology and cultural studies. The book discusses three landscape language (ethnophysiography) case studies with Indigenous peoples in Australia and the USA. It features a detailed discussion of transdisciplinarity and provides a comprehensive example of how this approach can be applied to complex dwelling relationships, which people, from different cultures, have with specific topographic environments, turning terrain into landscape. It involves using phenomenology as a transdisciplinary meta-paradigm and describes phenomenological methods for integrating physical and social sciences, including an analysis of the worldviews of Indigenous peoples (for example, Manyjilyjarra Jukurrpa as Heideggerian topology).
