This article investigates connections between climate justice and cultural sustainability through the case of Etëtung, or ‘Vanuatu Women’s Water Music’, as it is found in the ni-Vanuatu community of Leweton. Drawing on existing literature, interviews and field visit observations, I consider how and why Etëtung is proving increasingly important in local efforts toward cultural sustainability and climate justice (social justice as it relates to climate change). Specifically, I focus on three ways in which community members are employing the practice of Etëtung to progress both climate justice and cultural sustainability concerns: first, through the use of Etëtung to maintain and transmit cultural and environmental knowledge; second, through featuring Etëtung in cultural tourism; and third, through drawing on Etëtung to enable greater participation in the regional and international climate change discourse. As such, this article presents and reflects on one multifaceted approach to advancing dual cultural sustainability and climate justice interests, with potential relevance to other contexts in the Pacific and beyond.
