Micronutrient deficiencies are prevalent in crops and people in sub-Saharan Africa. Agronomic biofortification can increase yields and micronutrient contents of these crops, but there is a lack of direct evidence on the effectiveness to improve human health. This paper examines implementation of biofortification, which is hampered by limited information and access to inputs.
