The fourth Multistakeholder Gathering, held on the margins of the UN High-Level Meeting on NCDs and Mental Health, will provide high-level political leaders, technical government staff and leading civil society actors with practical insights on how countries can advocate for, implement, and sustain multisectoral governance and multistakeholder engagement for NCD and mental health response. It will spotlight country experiences, highlight data-driven and evidence-informed approaches, and introduce powerful narratives to mobilize action.
