In 2018, the UN Secretary-General launched his Action for Peacekeeping (A4P) initiative to strengthen peacekeeping by promoting collective action by all peacekeeping stakeholders. This was accompanied by the Declaration of Shared Commitments, endorsed by more than 150 member states. In 2021, to accelerate progress on implementation of the Shared Commitments, the Secretary-General launched Action for Peacekeeping + (A4P+), which consists of seven priority areas and two cross-cutting themes. With generous support from the Kingdom of the Netherlands, IPI has produced a series of publications focused on several of these priorities.
