More geographic targeting for reducing micro-nutrient deficiency


DAPA works with AgroSalud colleagues to target technology and set priorities for CIAT and partner’s biofortification initiatives.  A second research project on targeting biofortification was led by Emmanuel Zapata and colleagues.  The results of the study were recently published in the International Journal of Health Geographics.  Emmanuel skillfully employed weighted overlay  to identify potential sites where crop varieties with high content of iron, zinc and vitamin A could be beneficial to populations at risk of micronutrient deficiency.  The diagram above illustrates the method.  Factors important in the sighting of a biofortification intervention are weighted according to their importance. The study provides a preliminary assessment prior to more detailed site analysis about the possibility for establishing an intervention.
