Fighting malnutrition requires a multi-sectorial approach. The Research4Action report provides robust scientific insights on which WASH activities have a positive impact on undernutrition as well as a set of 6 recommendations to pave the way for better coordination. This session will explore what evidence says, how it can be translated into activities and illustrated by practical examples from the South Sudan WASH and Nutrition clusters, and other countries. Coordination being useless without sustainability, the Right2Grow team will present its vision for a community-led global movement that breaks the silos between WASH and Nutrition in emergency and development, and prioritizes local realities in order to achieve long lasting change. Together we conducted research and took practical action in the field to ensure that every child has the right to grow.
