(UN Chronicle) – The Sustainable Development Goals (SDGs) have now come into force and there is much hope for their potential to bring about positive change to the lives of millions of people. When they adopted the new development agenda, Member States pledged to leave no one behind and to “endeavour to reach the furthest behind”. They also reminded us that “there can be no sustainable development without peace and no peace without sustainable development”. The new agenda is set to transform a world confronted with challenges on a scale we have not experienced in decades. Violent conflicts in the Middle East, Africa and elsewhere are disrupting the lives of millions, and continue to fuel the largest movement of people the world has experienced since the Second World War.
