They have launched a nutrition improvement survey for children through distributing food supplements including Spirulina as one of the keys for theme 4 “Business model proposal and social implementation”. 
   On November 11th, they conducted a social demographic survey of parents at two elementary schools in a rural area of ​​Bahir Dar and held an explanatory meeting for parents about the survey. Parents asked some questions like “Why are spirulina buns distributed to only some children?”, but professors explained that success in this project leads future expansion of school lunch system. As a result, parents consented to their children participation in the survey.
