Sweeping goals to end poverty, inequality and other global ills are being derailed by climate change, conflicts and violence, the head of the United Nations told world leaders in New York on Tuesday, calling for a "decade of action."

Sustainable development needs more financing, investment in health and education, and broader access to technology to succeed, U.N. Secretary-General Antonio Guterres said at the first high-level review of the global goals adopted in 2015.

Launched with great fanfare and optimism, the 17 Sustainable Development Goals (SDGs) agreed by the 193 U.N. member states set out an ambitious "to-do" list tackling conflict, hunger, land degradation, gender inequality and climate change by 2030.
