Turning the Tide on Remnants of War at Sea? Toward the Principles for Protection of the Environment in Relation to Armed Conflicts

Abstract For a long time, the full impacts of armed conflicts on the marine environment have been ill-defined and largely neglected. World War I and II -era remnants of war at sea pose increasing threats to human and marine life, particularly over the coming decade, as they contaminate, pollute, or detonate toxic and hazardous substances into coastal and benthic ecosystems. The International Law Commission’s Principles for Protection of the Environment in Relation to Armed Conflicts aim to enhance protections for the marine environment before, during, and after conflict. In practice, this means navigating an uncoalesced legal regime and relying on established principles of international environmental law – particularly the duty to cooperate and share information. However, considerable knowledge gaps need to be addressed to remedy the vast legacy of war in the ocean, as the majority of remnants of war at sea remain under-assessed, in part, due to financial and technical constraints.
