Improving nutrition outcomes with better water, sanitation and hygiene: practical solutions for policies and programmes

This publication, jointly prepared by WHO, the United Nations Children’s Fund (UNICEF) and the United States Agency for International Development (USAID), summarizes the current evidence on the benefits of WASH for improving nutrition outcomes and describes how WASH (water, sanitation and hygiene) interventions can be integrated into nutrition programmes. It provides practical suggestions, targeted at nutrition programme managers and implementers, on both what WASH interventions should be included in nutrition programmes and how to include them. It also seeks to help the WASH community to better understand their role, both as providers of technical expertise in WASH interventions and in prioritizing longer-term improvements to WASH infrastructure in areas where undernutrition is a concern.
