Book excerpt: This is an open access book. The Critical Island Studies Consortium (CIS) was born in 2019 in Manila with the theme, “Critical Island Studies: The Islandic Archipelago, and Oceanic.” The CIS consortium aims at developing a new planetary perspective from which to invent an image of the environment and create a new sense of nature with which to seek environmental justice. This conference in Yogyakarta is composed of two related yet autonomous sections; one is hosted by Universitas Sanata Dharma (USD) and the other by Universitas Gadjah Mada (UGM). With USD and UGM taking the lead, CIS 2023 continues to carve out the vision of a new, more sustainable future for our planet.
