The United Nations Volunteers (UNV) programme is the UN organization that contributes to peace and development through volunteerism worldwide. Volunteerism is a powerful means of engaging people in tackling development challenges, and it can transform the pace and nature of development. Volunteerism benefits both society at large and the individual volunteer by strengthening trust, solidarity and reciprocity among citizens, and by purposefully creating opportunities for participation. UNV contributes to peace and development by advocating for recognition of volunteers, working with partners to integrate volunteerism into development programming, and mobilizing an increasing number and diversity of volunteers, including almost 8,000 experienced UN Volunteers, throughout the world. UNV embraces volunteerism as universal and inclusive, and recognizes volunteerism in its diversity as well as the values that sustain it: free will, commitment, engagement and solidarity.
