Before the SUN Movement was launched, there had been growing global recognition of the problems of undernutrition, and concern that the international system was failing to deal with it effectively. The 2008 Lancet series on maternal and child nutrition highlighted evidence about the high personal and economic costs of stunting and criticised the failure of a “fragmented and dysfunctional” international architecture to deal with it.
A number of agencies and working groups collaborated on early proposals for the SUN Movement with a “Framework for Action” and “Road Map”, both published in 2010. They highlighted the need to tackle stunting, to focus especially on the 1,000 day window of opportunity, from conception to a childs second birthday, and to embrace nutrition-sensitive approaches to tackle the underlying causes of malnutrition as well as nutrition-specific interventions to tackle its direct manifestations. They proposed that civil society, donors, UN agencies and the private sector should all collaborate to support country-led, multi-sectoral strategies to combat undernutrition. This was to be an informal partnership, and its role would be to catalyse support for countries prepared to “scale up nutrition”.
