Chemonics addresses the many pathways that lead to undernutrition through multi-sectoral approaches that integrate nutrition-specific and nutrition-sensitive interventions as well as social and behavior change principles. We begin at the community level, working with farmers, healthcare providers, and policymakers to reduce malnutrition and advance dietary diversity in the first 1,000 days. Together with stakeholders across the agriculture and food security, water, sanitation, and hygiene, gender, and global health sectors, we implement the diverse range of interventions to improve nutritional outcomes that form our holistic and resilient model.
