Sufficient nutrition remains a major challenge for rural households in the Sub-saharan region of Africa. Many rural households rely on cultivating traditional crops and food to maintain healthy and sufficient nutrition. However, in recent decades these smallholders have switched from subsistence styles to engaging in agricultural trade and growing cash crops. This shift causes land use history and management changes, such as crop rotation. However, how this change contributes to the micro-nutrition of crops and affects the micronutrition deficiencies of rural population in SSA remains unclear. Micronutrient deficiency is a form of malnutrition that can have a tremendous impact on the health and well-being of the affected population. It is more prevalent in rural areas where people have cereal-based diets.
The MSc project will look at how land use management may affect the micro-nutrition of crops. Two approaches can be followed:
(1) Using the data collected the Gashu et al., 2021, we will add land use history information to assess the impact of changes in agricultural management practices upon the nutritional quality of crops. Land use changes will be identified using time-series satellite images.
(2) Building a spatially explicit local model, using the crop grains collected during field campaigns. The grains will be collected from different study areas so that the impact of various management practices on the nutritional quality of crops can be assessed. The model will use remote sensing, various environmental variables and information on crop nutrients as input.
