Disarmament, Demobilization and Reintegration (DDR) is a process through which members of armed forces and groups are supported to lay down their weapons and return to civilian life. As a complex process, it comprehends political, security, social and economic dimensions aimed at creating an environment where a peace process, political and social reconciliation, as well as sustainable development, can take place.

To compile lessons learned from DDR programmes implemented throughout the 1990s and early 2000s, the Inter-Agency Working Group on DDR (IAWG-DDR) developed and published the Integrated Disarmament, Demobilization and Reintegration Standards (IDDRS) in 2006. The IDDRS have the objective to provide DDR practitioners operating in UN-mandated missions as well as non-mission settings with evidence-based guidance to jump-start new DDR processes. In 2017, to answer to the emerging challenges faced by DDR practitioners in new conflict contexts, the IAWG took the decision to undertake a comprehensive review of the IDDRS, which culminated with the launch of the revised UN Approach to DDR in November 2019. Such revision and the drafting of the new modules of the IDDRS has seen many IDDRS modules updated by the IAWG-DDR while other are under finalisation and validation from the 25 UN entities forming the IAWG.

UNITAR strategic goal in the thematic area of Disarmament, Demobilization and Reintegration (DDR) is to support national, regional and international stakeholders and practitioners through building and strengthening their capacities to implement emerging as well as traditional DDR programmes and processes in line with the international standards and guidelines, such as the UN Integrated Disarmament, Demobilization and Reintegration Standards (IDDRS) and the African Union Operational Guidance Notes (OGNs).

UNITAR is an active member of the United Nations Inter-Agency Working Group on Disarmament, Demobilization and Reintegration (IAWG-DDR) and of the Integrated DDR Training Group (IDDRTG).


“The United Nations Approach to DDR” – UNITAR self-paced online Course

First developed in 2017 and periodically revised to be in line with the most recent revised UN Approach to DDR, the goal of the course is to provide learners with key knowledge on the United Nations approach to Disarmament, Demobilization and Reintegration (DDR) guiding them through an interactive, practical and engaging overview of the Integrated DDR Standards, familiarizing them with its various components.

The course is composed of 5 online modules and one sub-module, covering all the key aspects of the IDDRS. The course is available in English and French on the UNITAR e-learning platform.

At the end of the course, learners will be able to:

  • Define DDR concepts and identify relevant policies and strategies, including the United Nations integrated approach to DDR;
  • Describe key elements of the revision of the Integrated DDR Standards (IDDRS);
  • Describe integrated DDR planning and programme design;
  • Analyse DDR operations, programmes and support activities, more specifically the processes of disarmament, demobilization and reintegration;
  • Integrate cross-cutting issues pertinent to DDR policies and strategies into DDR policies and strategies;
  • Link DDR programmes with other peace-building processes.


The course is revised regularly to integrate key knowledge and concepts from the most recent version of the new and revised modules of the IDDRS. An updated version has been launched in August 2021.  The updated French version will be available soon.

"Journey for Peace and Development" - Evolution and Impact of DDR

What is inside the complex notion of Disarmament, Demobilization and Reintegration (DDR)? How has it evolved over time? What impact does DDR have on people's lives and their communities and why should international actors support and engage in DDR processes worldwide? As a member of the Inter-Agency Working Group on Disarmament, Demobilization and Reintegration (IAWG-DDR) and with the help of original video material obtained from diverse DDR contexts, UNITAR proposes you to learn more about DDR and individual journeys to peace, stability and development. The release of the video was dedicated to the Official Launch of the Revised United Nations Integrated DDR Standards on 19 November 2019.
