The Day's theme for 2016 when ?is The Sustainable Development Goals: Building Blocks for Peace. ?The 17 Sustainable Development Goals were unanimously adopted by the 193 Member States of the United Nations at an historic summit of the world's leaders in New York in September 2015. The new ambitious 2030 agenda calls on countries to begin efforts to achieve these goals over the next 15 years. It aims to end poverty, protect the planet, and ensure prosperity for all.The Sustainable Development Goals are integral to achieving peace in our time, as development and peace are interdependent and mutually reinforcing.?

Sustainability addresses the fundamental needs of the present without compromising the ability of future generations to meet their own needs. Modern challenges of poverty, hunger, diminishing natural resources, water scarcity, social inequality, environmental degradation, diseases, corruption, racism and xenophobia, among others, pose challenges for peace and create fertile grounds for conflict. Sustainable development contributes decisively to dissipation and elimination of these causes of conflict and provides the foundation for a lasting peace. Peace, meanwhile, reinforces the conditions for sustainable development and liberates the resources needed for societies to develop and prosper.?

Every single one of the 17 Sustainable Development Goals is a building block in the global architecture of peace. It is critical that we mobilise means of implementation, including financial resources, technology development and transfer, and capacity-building, as well as the role of partnerships. Everyone has a stake and everyone has a contribution to make.?
