This funding represents a contribution to the United Nations Development Programme (UNDP) to finance its role as a member of the joint support team of the Global Partnership for Effective Development Co-operation (GPEDC). This funding, along with other donors’ contributions, helps the GPEDC achieve its mandate. GPEDC seeks to improve the effectiveness of development cooperation through the fourth round of monitoring for effective development cooperation. It also supports the GPEDC’s inclusive global platform bringing together governments, civil society, the private sector, trade unions, parliamentarians, and others. The 2023 to 2026 GPEDC Programme of work aims to enable better alignment of development cooperation efforts with the Busan effectiveness principles through its reformed monitoring process at country level. In particular, it looks at ownership by partner countries, a focus on results, inclusive partnerships, transparency and mutual accountability. It also aims to feed official data to SDG 17 on partnerships. Project activities include: (1) identifying key action points, through inclusive and country-led processes, on how to improve the design and quality of partnerships in participating partner countries; (2) mobilising relevant policy communities to broaden the ‘effectiveness ecosystem’; (3) enabling country governments to drive monitoring, dialogue, action and knowledge sharing; (4) fostering learning, mutual understanding, trust, and accelerate progress on commitments through policy and behaviour change at country level; and (5) mobilizing political buy-in for and promote uptake of monitoring findings across countries and contexts.

The main objective of the GPEDC’s 2023 to 2026 Work Programme is to monitor the effectiveness of development cooperation for all stakeholders in a way that drives behaviour change in line with the principles for effective development cooperation and in support of the SDGs.
