Indonesia is a disaster-prone archipelagic country and one of the world's largest emitters. Climate change has increased the risk of disasters in Indonesia, such as rising sea levels leading to floods. This is undoubtedly a threat to the Indonesian population in coastal areas and small islands. They will be forced to become Internally Displaced Persons (IDPs) if sea levels continue to rise and drown their houses. The number of IDPs in Indonesia has increased significantly in recent years. While IDPs have a legal status and are entitled to protection from the state, there is unfortunately no specific provision for IDPs due to climate disasters in Indonesia. This article examines the legal protection afforded to IDPs in Indonesia as a result of climate-related disasters; deals with the existing legal framework for IDPs; and assesses its adequacy in addressing the specific challenges faced by climate-related IDPs.
