At its 79th session, the UN General Assembly requested the United Nations Office for Disarmament Affairs (UNODA) to conduct a study on obliterated markings and methods for marking recovery in the context of the International Tracing Instrument (ITI).

Obliterated markings refer to the deliberate erasing or alteration of identifying marks on small arms and light weapons (SALW), such as serial numbers or factory codes.

Supporting AI practitioners in addressing critical risks – launching the Handbook on Responsible Innovation in AI for International Peace and Security

Driven by factors like breakthroughs in machine learning, access to data, and hardware innovations, advances in AI are being employed in fields from drug discovery to supply chain management. However, the same advances also present real risks to international peace and security.

ODA at a glance

UNODA supports the development and implementation of practical disarmament measures after a conflict, such as disarming and demobilizing former combatants and helping them to reintegrate in civil society.

Established in January 1998 

United Nations ODA was established in January 1998 as the Department for Disarmament Affairs which was part of the SG’s programme for reform in accordance with his report to the General Assembly (A/51/950).

Supports General and complete disarmament

The Office for Disarmament Affairs supports multilateral efforts aimed at achieving the ultimate goal of general and complete disarmament under strict and effective international control. The mandate for the programme is derived from the priorities established in relevant General Assembly resolutions and decisions in the field of disarmament, including the Final Document of the Tenth Special Session of the General Assembly, the first special session devoted to disarmament (resolution S-10/2).

Provides support in the area of disarmament

UNODA provides substantive and organizational support for norm-setting in the area of disarmament through the work of the General Assembly and its First Committee, the Disarmament Commission, the Conference on Disarmament and other bodies. It fosters disarmament measures through dialogue, transparency and confidence-building on military matters, and encourages regional disarmament efforts; these include the United Nations Register of Conventional Arms and regional forums.

Provides information to Member States

UNODA provides objective, impartial and up-to-date information on multilateral disarmament issues and activities to Member States, States parties to multilateral agreements, intergovernmental organizations and institutions, departments and agencies of the United Nations system, research and educational institutions, civil society, especially non-governmental organizations, the media and the general public.

Structure of ODA

What is disarmament?

Throughout history, countries have pursued disarmament to stop arms races, build trust, and protect people from harm. Disarmament has been central to the work of the United Nations since its founding, and it is critical for building a more secure and peaceful world. But what actually is disarmament? This video introduces audiences to the ideas and concepts behind disarmament and arms control.

How does disarmament and arms control work?

This video takes a look at the processes and mechanisms behind modern disarmament and arms control, and how we work together to realise disarmament goals.

How to engage

In this video we look at how individuals can engage with disarmament, and the importance of strengthening cooperation and coordination at all levels. We also look at the need to engage with more diverse groups to bring new perspectives, expertise and ideas to the table.

Disarmament in the 21st Century

This video introduces audiences to “Securing our Common Future”, the Secretary-General’s Agenda for Disarmament. The Agenda is based on four key pillars designed to bring the objectives of disarmament into the 21st century. Examining each of the pillars, this video looks at how we approach disarmament today.
