The importance of scientific evidence to guide nutrition policy and programme design is well established. Nevertheless, there are still critical gaps in the evidence to inform nutrition programme priorities and achievements, and strong pleas have been made for improving the collection and use of evidence in the nutrition sector.
In an effort to address these evidence gaps, the Global Nutrition Report of 2014 and the Micronutrient Forum 2014 Global Conference proceedings specifically highlighted the need to pay more attention to programme coverage as the main approach to assessing the availability, access and utilisation of nutrition programmes. This paper calls for renewed and coordinated efforts to better track programme coverage and to build systems for data-driven decision-making.
