This article examines engagements with the natural environment in Indonesian contemporary art, with a specific focus on Yogyakarta-based multimedia artist Setu Legi. After discussing various historical models of Indonesian creative engagements with the environment, I argue that Legi’s work deals with environmental problems by personalising the political as well as highlighting political aspects of the personal. Using the work of Félix Guattari and T J Demos, I show how his art offers a form of eco-aesthetics that disentangles the interconnections between art, politics and the natural environment. I analyse Legi’s critical exploration of the concept of ‘homeland’ (tanah air) and the geopolitics of West Papua through his creation of alternative maps of the Indonesian archipelagic state. Finally, I demonstrate how Legi relates cultural and environmental destruction as well as possible solutions for these problems to a range of religious and spiritual ideas and practices in Indonesia.
