Preventive Diplomacy and Mediation

The most effective way to diminish human suffering and the massive economic costs of conflicts and their aftermath is to prevent conflicts in the first place.  The United Nations plays an important role in conflict prevention, using  diplomacygood offices and mediation.  Among the tools the Organization uses to bring peace are special envoys and political missions in the field.

Peacekeeping

Peacekeeping has proven to be one of the most effective tools available to the UN to assist host countries navigate the difficult path from conflict to peace. Today's multidimensional peacekeeping operations are called upon not only to maintain peace and security, but also to facilitate political processes, protect civilians, assist in the disarmament, demobilization and reintegration of former combatants; support constitutional processes and the organization of elections, protect and promote human rights and assist in restoring the rule of law and extending legitimate state authority. Peacekeeping operations get their mandates from the UN Security Council; their troops and police are contributed by Members States; and they are managed by the Department of Peacekeeping Operations and supported by the Department of Field Support at the UN Headquarters in New York. There are 15 UN peacekeeping operations currently deployed and there have been a total of 71 deployed since 1948.

Peacebuilding

United Nations peacebuilding activities are aimed at assisting countries emerging from conflict, reducing the risk of relapsing into conflict and at laying the foundation for sustainable peace and development. The UN peacebuilding architecture comprises the Peacebuilding Commission, the Peacebuilding Fund and the Peacebuilding Support Office. The Peacebuilding Support Office assists and supports the Peacebuilding Commission with strategic advice and policy guidance, administers the Peacebuilding Fund and serves the Secretary-General in coordinating United Nations agencies in their peacebuilding efforts.

Countering Terrorism

The United Nations is being increasingly called upon to coordinate the global fight against terrorism. Eighteen universal instruments against international terrorism have been elaborated within the framework of the United Nations system relating to specific terrorist activities.  In September 2006, UN Member States adopted the United Nations Global Counter-Terrorism Strategy. This was the first time that Member States agreed to a common strategic and operational framework against terrorism.

Disarmament

The General Assembly and other bodies of the United Nations, supported by the Office for Disarmament Affairs, work to advance international peace and security through the pursuit of the elimination of nuclear weapons and other weapons of mass destruction and the regulation of conventional arms.
