The document discusses the 1,000 Days initiative to reduce child undernutrition. It aims to jumpstart implementation of the Scaling Up Nutrition Framework and Roadmap by focusing on undernutrition during pregnancy and the first 1,000 days of a child's life (from conception to age 2). The 1,000 Days effort was launched in 2010 by the US Secretary of State and Irish Foreign Minister. It seeks to align resources and build partnerships to address undernutrition, which impacts health, development and mortality. The Scaling Up Nutrition Framework guides international efforts and is endorsed by over 100 partners. It emphasizes evidence-based, cost-effective nutrition interventions during the critical first 1,000 day window of opportunity.
