This year's WBW theme is Breastfeeding: a key to Sustainable Development. 2016 commemorates the start of the Sustainable Development Goals (SDGs). A broad approach using the sustainability theme is thus relevant and inclusive.
By linking breastfeeding to the SDGs, the breastfeeding movement (and beyond) will be able to connect with a variety of development issues over the next 15 years (by 2030) for maximum impact.
WBW materials cover the main links between breastfeeding and the SDGs along 5 broad themes (1) nutrition/food security, 2) health, well-being and survival, 3) environment and climate change, 4) work productivity, empowerment, social protection, and 5) sustainable partnerships and rule of law.
