The United Nations International Law Commission (ILC) has decided to include the topic “sea-level rise in relation to international law” in its programme of work and established a Study Group. The Study Group will focus on the subject of sea-level rise in relation to the law of the sea. The ILC expects to receive, by 31 December 2019, examples from States of their practice that could be relevant (even if indirectly) to sea-level rise or other changes in circumstances of a similar nature. Such practice could, for example, relate to baselines and where applicable archipelagic baselines, closing lines, low-tide elevations, islands, artificial islands, land reclamation and other coastal fortification measures, limits of maritime zones, delimitation of maritime boundaries, and any other issues relevant to the subject.
