FOCUS 1000 advocates with duty bearers – such as national and local government, parliamentarians, and community leaders – for increased commitment, resources, and enactment/enforcement of laws and policies that support the wellbeing of the child during the first 1000 days. Our advocacy efforts include strengthening the role of civil society in scaling-up nutrition and immunization, prohibiting child marriage/teenage pregnancy, and improving water, sanitation, and hygiene conditions. As a member of the Health Sector Steering Group (HSSG), we advocate with government and development partners to enhance civil society participation in health systems strengthening.
