Indigenous Heritage and Identity of the Last Elephant Catchers in Northeast Thailand examines how the end of elephant catching has affected the heritage and identity of the Kui Ajiang, offering an analysis that calls for close attention to the broader currents of Thai history and the development of Thai environmental and cultural heritage policies. Furthermore, the term Authorised Environmental Discourse (AED) is introduced in tandem with Laurajane Smith's Authorised Heritage Discourse (AHD) to portray how heritage embedded in nature and culture reflects impacts of political authority and how a community responds to threats of loss and challenges to the authenticity of its traditions.
