Early childhood development (ECD) is the foundation for sustainable development. Giving every child, no matter where they live, the best start in life is the best way to ensure healthy and prosperous individuals, communities and countries. ARNEC celebrates the inclusion of ECD in the global development agenda. ARNEC believes that ECD cannot be isolated from the rest of the sustainable development goals (SDGs). It is central to achieving the SDGs. In the words of United Nations Secretary-General Ban Ki-moon: “The Sustainable Development Goals recognise that early childhood development can help drive the transformation we hope to achieve over the next 15 years.” ARNEC has produced this brief to inform members of the possibilities offered by the new global agenda to improve the lives of young children and their families across the region. It will be the first in a series of briefs that will provide further information and guidance for members about how to ensure that the new goals deliver for all children.
