The OECD’s Development Assistance Committee (DAC) conducts peer reviews of individual members once every five to six years. Reviews seek to improve the quality and effectiveness of members’ development co-operation, highlighting good practices and recommending improvements. Portugal mobilises its whole of government expertise with a strong focus on partner country ownership. Building on long-standing and close bilateral relations, it concentrates its funding on countries most in need. Through effective international advocacy, the country champions triangular co-operation and has fostered agreement amongst European Union (EU) members on issues such as strengthening Team Europe’s commitment to human development when it held the Presidency of the EU Council. However, Portugal can make more out of the wide participation of state and non-state actors in its development co-operation. This peer review provides a set of recommendations to improve co-ordination across government, pull bilateral efforts together, focus more on outcomes and take action to increase official development assistance (ODA).
