The SUN Civil Society Network (CSN) is a global network of over 3,000 civil society organizations in 53 countries working to eliminate malnutrition. The CSN was established in 2011 to mobilize civil society actors and coordinate with other SUN networks to support country governments. Key roles of CSN members include raising awareness, advocacy, capacity building, and implementing nutrition-specific and nutrition-sensitive interventions. The CSN has achieved policy changes, increased commitments and budgets for nutrition, and greater accountability in several countries. Going forward, the CSN will continue efforts to reduce malnutrition and address its root causes.
