This book is the first in the Tales Be Told series, which documents how the UN Network for SUN (UNN4SUN) fosters collective action on nutrition in various countries and adds value to the Scaling Up Nutrition (SUN) Movement. In Series 1, read about UNN4SUN's efforts to elevate nutrition to the highest level to bolster the multisectoral, multi-stakeholder approach. This includes the engagement of United Nations Resident Coordinators (UNRCs) in the national nutrition agenda, capitalizing on the enhanced role of UNRCs bestowed through the UN reform. Other stories profile the Network's expanding membership, country facilitation support and its portfolio of analytical tools. The latter explore how the analytics are door openers, not only among technical specialists, but also among policy-makers and executive powers.
