There are many evidence gaps in the delivery of humanitarian food/nutrition aid. Evaluation of the relative cost‐effectiveness of dietary response projects is confounded by the fact that different projects can have different objectives (USAID, 2015). Ethiopia has made progress in meeting emergency needs, including through the Government of Ethiopia-led Productive Safety Net Programme (PSNP), which is a combination of food and cash assistance. Results show that the average household food insecurity gap (incidences when households cannot meet their food needs) dropped from 3.6 months to 2.3 months (The World Bank Group, 2013). A qualitative survey in Tigray, Northern Ethiopia, revealed that receipt of PSNP food-aid was linked socio-demographic attributes, among which marital status, age and size of family were decisive factors (Adazi et al., 2017). There is no evidence that PSNP reduces chronic or acute undernutrition (Berhane et al., 2017).
