Geospatial modelling of soil geochemistry at national-scale for improved human nutrition

PhD Candidate: Christopher Chagumaira

Variation of human micronutrient status is partly driven by the spatial variation of the soil, and related variables, at national scale. Interventions targeting micronutrient deficiencies need to take account of national-scale soil variation, and mapping this variation effectively is important. This project explores how soil nutrient status is most efficiently mapped at the national scale in sub-Saharan Africa. It explores the implications of uncertainty in spatial predictions of soil nutrient status for key decision makers. This will help these decision-makers, like agricultural and health practitioners, assess the risk of micronutrient deficiencies in their area.
