To examine the science, policy, and practice surrounding supporting family and community investments in young children globally and children in acute disruptions, the National Academies of Sciences, Engineering, and Medicine held a workshop in partnership with the Ethiopian Academy of Sciences in Addis Ababa, Ethiopia, from July 27-29, 2015. The workshop examined topics related to supporting family and community investments in young children globally. Examples of types of investments included financial and human capital. Participants also discussed how systems can better support children, families, and communities through acute disruptions such as the Ebola outbreak. Over the course of the 3-day workshop, researchers, policy makers, program practitioners, funders, young influencers, and other experts from 19 countries discussed how best to support family and community investments across areas of health, education, nutrition, social protection, and other service domains. This report summarizes the presentations and discussions from the workshop.
