From confronting climate change and extreme forms of poverty to protracted conflict and the erosion of human rights, effective international cooperation represents both a moral and practical imperative. Given these colossal challenges, the coming together of world leaders in New York at this month’s SDG Summit and next year’s Summit of the Future is both timely and critical. With only 15 percent of the Sustainable Development Goals’ targets on track this decade (and over 500 million people still likely to live in extreme poverty by 2030), achieving success in both summits depends on the identification and pursuit of the deep and varied connections between them.
