The UN began reforms in 2000 to strengthen its capacity for peacekeeping operations in response to increasing demands and complex challenges. Peacekeeping faced deploying large, expensive, and complex operations; transitioning stable operations; and building local capacity for long-term peace. The Secretary-General established an independent panel in 2014 to assess and advise on evolving needs and improving UN peace operations, including changing conflict nature, mandates, partnerships, and protection of civilians.
