Both human activities and climate change have changed landscapes significantly, especially in coastal areas. Sea level rise and land subsidence foster tidal floods and permanent inundations, thus changing and limiting land use. Though many countries, including Indonesia, are aware of these phenomena, the legal status of this permanently inundated land remains unclear. Indonesia refers to this land legally as obliterated land. This qualification makes former landowners uncertain, as it does not recognize their previous land rights, and creates disputes during land acquisition. In view of policy pressures to develop large-scale projects, the government often fails to include obliterated land legally during land acquisition processes for these projects. This causes unfair and disputed compensation for those former landowners. Current scientific discourses do not yet address this legal quandary. This study therefore has the following three aims: (1) to describe the legal, institutional and
