Project Detail


Dietary micronutrient deficiencies (MNDs) are widespread in sub-Saharan Africa (SSA). Micronutrient deficiencies impair growth, cognitive development and immune function, especially in women and infants. Our team has pioneered geographically-informed approaches to improve estimates of micronutrient deficiency risks along the Agriculture-Nutrition-Public health axis. From a nutritional perspective, we have mapped biomarkers of MND risks and uncertainties in Malawi using geostatistical methods to inform policy decisions and identify knowledge gaps. From an agricultural perspective, we have conducted health economic impacts of zinc (Zn) deficiency in Ethiopia, SSA and S. Asia, which includes the use of new soil maps which are being developed by the Africa Soil Information Service (AfSIS) to stimulate private- and public-sector investment in the fertilizer sector. There is an immediate opportunity to further integrate nutrition and agriculture R&D using spatial frameworks to inform policies to reduce MNDs. The aim of GeoNutrition is to support policy decisions which seek to reduce MNDs by the Governments of Ethiopia, Malawi, and the wider region.
