This training module will introduce the Quadrennial Comprehensive Policy Review (QCPR) of operational activities for development of the United Nations system (UNDS), including the enhanced role of the resident coordinator system and other elements of the recently concluded repositioning exercise. It will provide the context for the QCPR and give an overview of the changes made by the UN development system in the last QCPR cycle. The module will also discuss priority areas for the 2024 QCPR and how the UN system is scaling up support for SDG acceleration, including through the implementation of the 2023 SDG Summit Political Declaration, focusing on six key transition areas: (1) food systems transformation; (2) energy transitions and access; (3) digital connectivity; (4) education and skills gaps; (5) decent jobs and social protection including healthcare; and (6) triple planetary crisis: climate change, biodiversity loss and pollution.
