Quoting from www.un.org/youthday:
«On 17 December 1999, in its resolution 54/120, the United Nations General Assembly endorsed the recommendation made by the World Conference of Ministers Responsible for Youth (Lisbon, 8-12 August 1998) that 12 August be declared International Youth Day.
Since the adoption of Security Council Resolution S/RES/2250 (2015) in 2015, there is growing recognition that as agents of change, young people’s inclusion in the peace and security agenda and in society more broadly, is key to building and sustaining peace. Another Security Council Resolution S/RES/2282 (2016) reaffirms the important role youth can play in deterring and resolving conflicts, and are key constituents in ensuring the success of both peacekeeping and peacebuilding efforts.
“Youth Building Peace”
International Youth Day 2017 is dedicated to celebrating young people’s contributions to conflict prevention and transformation as well as inclusion, social justice, and sustainable peace.
The 2030 Agenda for Sustainable Development committed to fostering peaceful and inclusive societies and affirmed that “Sustainable development cannot be realized without peace and security”. Goal 16 aims to ensure responsive, inclusive, participatory and representative decision-making at all levels. The World Programme of Action for Youth, which provides a policy framework and practical guidelines to improve the situation of young people, also encourages “promoting the active involvement of youth in maintaining peace and security”.»
