This treaty would encourage countries to collaborate on underwater munitions research, science, and policy including environmentally friendly remediation in the affected regions. IDUM is an internationally recognized body where all stakeholders (diplomats, government departments including external affairs, environmental protection and fishery, fossil fuel and fishing industry, salvage divers, militaries, and others) can come together in an open and transparent forum to discuss underwater munitions, seek solutions, and promote international cooperation on related issues. Since the creation of the foundation, IDUM has successfully hosted five international dialogues on Sea Dumped Weapons (SDW) related issues. Their work is recognized by inter-governmental institutions such as the United Nations (UN) and the Organization for the Prohibition of Chemical Weapons (OPCW). The UN identified their work in the 2014 ‘UN Resolution on Sea Dumped Munitions’ and in the 2013 Secretary General’s report titled ‘Cooperative Measures on Sea Dumped Chemical Munitions.‘ In 2014, the OPCW report titled ‘Third Review Conference of State Parties’ outlined the need for international cooperation on SDWs. Apart from working to bring together the various stakeholders that can create effective policy responses to SDWs,
