The destabilizing accumulation, illicit transfer and misuse of small arms and light weapons continue to initiate, sustain and exacerbate armed conflict and pervasive crime globally.

Treaties and Instruments

In 2001, countries adopted the Programme of Action to Prevent, Combat and Eradicate the Illicit Trade in Small Arms and Light Weapons in All Its Aspects (PoA). In the instrument, governments agreed to improve national small arms regulations, to strengthen stockpile management, to ensure that weapons are properly and reliably marked, to improve cooperation in weapons tracing, and to engage in regional and international cooperation and assistance. Within the PoA framework, the General Assembly adopted the International Tracing Instrument (ITI) in 2005, a global instrument for cooperation in weapons tracing. Improving weapons tracing is now part of the 2030 Agenda for Sustainable Development. Together, both instruments constitute the normative framework on small arms and light weapons, which all UN Member States have agreed upon.

States periodically report on the implementation of the PoA and ITI  and review implementation efforts at Biennial Meetings of States and Review Conferences. Additionally, countries have held Meetings of Governmental Experts (MGE) to benefit from the knowledge of technical specialists on matters pertaining to small arms control.

The global framework of treaties and instruments also includes the Firearms Protocol and the Arms Trade Treaty. In addition, there are regional instruments and regional roadmaps to control and regulate small arms and light weapons.

The UN process related to small arms and light weapons

The General Assembly, compromised of all 193 UN Member States, adopts annually the omnibus resolution on “The illicit trade in small arms and light weapons in all its aspects” as well as the resolution on “Assistance to States for curbing the illicit traffic in small arms and light weapons and collecting them”. Both resolutions mandate the UN’s small arms process and are informed by the annual report of the Secretary-General to the General Assembly. 

The Security Council —the primary organ of the United Nations responsible for the maintenance of international peace and security—remains actively seized of the small arms and light weapons challenge. It has addressed small arms and light weapons-related issues across its agenda, from Security Sector Reform to arms embargoes to counter-terrorism and sustaining peace, while also treating these matters in country-specific and regionally-focused contexts.

In 1999, the Security Council first addressed the issue of small arms as a standalone agenda item. In 2013, the Council adopted resolution 2117 (2013) on small arms, which focused on the illicit transfer, destabilizing accumulation and misuse of small arms and light weapons. Resolution 2220 (2015) contained further provisions aimed at bolstering international cooperation, effective implementation of UN arms embargoes and support to the Arms Trade Treaty. The Council issued Presidential statements on small arms in 1999, 2001, 2002, 2004, 2005 and 2007.

Beginning in 2008, the Secretary-General has reported regularly to the Security Council on this issue in the form of a substantive report, traditionally on a biennial basis.

In 2019, a resolution dedicated to the African Union’s flagship initiative “Silencing the Guns in Africa” was adopted. The effective implementation of relevant arms control instruments and regimes, in particular those related to small arms and light weapons, are referenced in several parts of the resolution, thus illustrating the criticality of tackling illicit arms to achieving a conflict-free Africa.

The use of arms- and ammunition-related language, principally related to small arms and light weapons, in UN Security Council resolutions has evolved significantly over the last three decades. This evolution reflects the increasing variety of United Nations operations, weapons and ammunition management-related challenges and programmatic responses, as well as the emergence of new multilateral conventional arms control frameworks and practices.

The Human Rights Council regularly addresses the impact of arms transfers and civilian acquisition, possession and use of firearms on human rights. It thereby focuses on the impact of arms on the enjoyment of human rights and promotes efforts to protect those rights more effectively.

The United Nations Coordinating Action on Small Arms (CASA) is the UN system-wide internal-agency coordination mechanism on small arms, the arms trade, ammunition and armed violence issues. Since its inception in 1998, the CASA has been taking stock of diverse and specialized expertise of 24 UN partners from a wide variety of perspectives, including economic and social development, human rights, disarmament, organized crime, terrorism, conflict prevention, peacekeeping, public health, environment, gender and children. CASA aims to innovate itself as the main platform for coordinating holistic UN action to assisting States regarding the aforementioned  issues, as a key component of the Secretary-General’s prevention agenda. Most recently, CASA focuses on supporting country-level programming by leveraging closer cooperation within the UN and with regional actors and civil society.

UNODA also actively supports the comprehensive mainstreaming of gender perspectives in all dimensions of small arms and light weapons control.

Africa Amnesty Month: Working with the African Union to reduce illicit small arms and light weapons

In the context of the broader United Nations support to the African Union flagship initiative of “Silencing the Guns in Africa by the year 2020, mandated through Security Council Resolution 2457 (S/RES/2457), the United Nations Office for Disarmament Affairs together with the African Union Commission helped seven (7) African States in 2020 to implement the “Africa Amnesty Month”.

The Africa Amnesty Month was established in 2017, as part of the African Union Master Roadmap of Practical Steps to Silence the Guns in Africa by the year 2020, or short, “AU Master Roadmap”. The AU Assembly (Decision 645 (XXIX)) declared the month of September each year until 2020 “Africa Amnesty Month” for the surrender and collection of illegally owned weapons, in line with the African and international good practices.

In 2020, the joint AUC-UNODA project took place in seven African countries, with financial support from Germany and Japan. These countries were the Central African Republic, the Democratic Republic of the Congo, Kenya, Burkina Faso, Cameroon, Ethiopia and Côte d’Ivoire. The project will continue its support in 2021 and 2022. Main project components includedeffective communication and outreach on the negative effects of illicit possession of SALW and ammunition and the general call to hand them over to the national authorities, trust-building between law enforcement and communities, collection of weapons and ammunition, safe storage, marking and record-keeping, and public destruction.

To foster regional and national ownership, the Regional Centre on Small Arms (RECSA) was chosen as implementing partner for the 2020 Africa Amnesty Month. RECSA’s primary mandate is the support of its 15 Member States, from East and Central Africa, in the implementation of the Nairobi Protocol.

National Focal Points and National Commissions on small arms control led the project at the country level. These are governmental entities with the mandate to handle national small arms control related matters, such as safe storage of weapons and ammunition, record-keeping, but also voluntary weapons collection, and destruction. This setting provided for regionally and nationally owned processes based on nationally and regionally developed action plans.

In alignment with 2030 Agenda for Sustainable Development, the Africa Amnesty Month significantly contributes to the achievement of SDG Target 16.4 on the significant reduction of illicit arms flows.
