DATABASE ON MULTILATERAL PEACE OPERATIONS
Definitions and Methodology
The database contains information on
operations that are conducted under the authority of the UN and
operations conducted by regional organizations or by ad hoc coalitions
of states that were sanctioned by the UN or authorized by a UN Security
Council resolution, with the stated intention to: (a) serve as an
instrument to facilitate the implementation of peace agreements already
in place, (b) support a peace process, or (c) assist conflict
prevention and/or peace-building efforts.
SIPRI employs the UN Department of Peacekeeping Operations description of peacekeeping as a mechanism to assist conflict-ridden countries to create conditions for sustainable peace––this may include monitoring and observing ceasefire agreements; serving as confidence-building measures; protecting the delivery of humanitarian assistance; assisting with the demobilization and reintegration process; strengthening institutional capacities in the areas of judiciary and the rule of law (including penal institutions), policing, and human rights; electoral support; and economic and social development. The database thus covers a broad range of peace missions to reflect the growing complexity of mandates of peace operations and the potential for operations to change over the course of their mandate. However, good offices, fact-finding or electoral assistance missions are not included in the database.

Definitions and
Conventions
- Peace operations which are initiated in the reporting year and new states joining an existing operation appear in bold text.
- Operations and individual state participation which ended in the reporting year are shown in italics.
- Designated lead states (those that either have operational control or contribute the most personnel) are underlined.
- Legal instrument: refers to the legal basis for the establishment of an operation. For example, UN Security Council resolutions or formal decisions by regional organizations.
- Location: refers to the country in which a mission operates. Where applicable a specific region of the country is given.
- Start date: refers to the date of first deployment.
- Authorized personnel numbers: refers to the most recently approved staffing level. In certain cases, particularly non-UN operations, no figure can be given since there is no authorized personnel level set by the mandate of the operation.
- Actual personnel numbers: refer to the current strength of the
operation.
- Fatalities are recorded as (i) a total from the beginning of the mission until the last reported date and (ii) as a total for the reporting year. Where available, data on the cause of death––accidental, hostile acts, and, illness––are listed.
- Budget figures are
given in millions of US dollars. Conversions
from budgets set in other currencies are based on the aggregated market
exchange rates of the International Monetary Fund (IMF) for the
reporting year and are expressed in current dollar terms. Budget
figures presented in the database or in the
SIPRI Yearbook are best viewed as estimates and the budgets for
different missions should not be compared for the following reasons:
- Budget figures presented for UN
operations refer to core
operational costs, which among other things include the cost of
deploying personnel, per diems for deployed personnel and direct
non-field support costs (e.g., requirements for the support account for
peacekeeping operations and the UN logistics base in Brindisi). The
cost is shared by all UN member states through a specially derived
scale of assessed contributions that takes no account of their
participation in the peacekeeping operations.
- Political and peace-building missions are funded through regular budget assessments.
- UN peacekeeping budgets do not cover programmatic costs, such as those for DDR, which are financed by voluntary contributions.
- Budget figures for operations conducted by regional organizations such as the EU and NATO typically refer only to common costs. This includes mainly the running costs of EU and NATO headquarters (the costs of civilian personnel and operations and maintenance) and investments in the infrastructure necessary to support the operation. The costs of deploying personnel are borne by individual sending states and do not appear in the budget figures given here.
- Most EU missions are financed in one of two ways, depending on whether they are civilian or military missions. Civilian missions are funded through the Community Budget, while military missions or missions with military components are funded through the Athena mechanism, a financial and administrative instrument, to which only the participating member states contribute.
- Budget figures for peace operations by other organizations and in general the ad hoc missions may include programme implementation.
Note: Figures presented in
the database may differ from past SIPRI yearbooks because information
in the database has been retroactively converted to reflect the new
methodology of budget conversion. In previous years, figures as of 31
Dec. were used in the peace missions table. The change to using the
IMF’s aggregated market exchange rates limits the inconsistency of the
budget data owing to fluctuating currency exchange rates.
Sources
Data on multilateral peace operations are obtained from the following categories of open source:
(a) official information provided by the secretariat of the organization;
(b) information from the mission on the ground, either in official publications or in responses to annual SIPRI questionnaires;
(c) information from national governments contributing to the mission in question; and
(d) secondary sources consisting of specialist journals; research reports; news agencies; and international, regional and local newspapers.
Unless otherwise stated, all figures are as of 31 December of the reporting year or as of the date on which the mission closed.
