Evaluation of the Scaling Up Nutrition 3.0 Strategy

The Scaling Up Nutrition (SUN) Movement, launched in 2010 by the UN Secretary-General, is a country-driven initiative currently led by 66 countries and four states of India. It brings together stakeholders through Civil Society (CSN), Business (SBN), UN Nutrition (UNN), and Donor (SDN) networks. This evaluation assesses the implementation and effectiveness of the SUN 3.0 Strategy (2021-2025) to inform its remaining period and guide the Movement’s future direction. It examines progress on strategic objectives, the effectiveness of governance and coordination mechanisms, and SUN’s adaptability to global and national challenges.

Using a mixed-methods approach, the evaluation combines desk reviews, key informant interviews, focus group discussions, an e-survey and in-depth case studies in Costa Rica, Ethiopia, Mali, Pakistan, Timor-Leste, and Somalia. The analysis follows OECD-DAC criteria (relevance, effectiveness, efficiency, sustainability, gender, and youth), applying Collaborative Outcome Reporting and Most Significant Change techniques to validate findings. The results provide evidence-based recommendations to enhance SUN’s effectiveness, strengthen accountability, and optimise stakeholder collaboration.
