The objective of this study was to determine the minimum cost of a nutritious diet for children: 6-8 months, 9-11months, and 12-23 months and women (15-49 years): non-pregnant/ non-lactating, pregnant and lactating by modelling locally available foods with or without wild plant foods. Three pastoralists and three agro-pastoralists villages were randomly selected from a list. Market surveys were conducted in each village for plenty and lean seasons in 2016. Focus group discussions (FGD) were held with ten women per village to determine culturally accepted dietary habits (minimum and maximum constraints of food) and these constraints were verified against the 25th and 75th percentiles of actual dietary intake from a 24h recall tool applied to 180 households. Results from a FGD on agrobiodiversity following the 4- cell methodology developed by Bioversity International were used to select three wild vegetables and three wild fruits for modelling. All data were entered in the Cost of Diet software developed by “Save the Children UK” to model a Locally Adapted Cost Optimised Nutritious (LACON) diet.
