Anemia in children aged 6–59 months was significantly associated with maternal anemia status in rural Zimbabwe (2022)
Journal Article

Globally, anemia is a public health problem affecting mostly women of reproductive age (WRA, n=452) and children aged 6–59 months (n=452) from low- and lower-middle-income countries. This cross-sectional study assessed the prevalence and determinants... Read More about Anemia in children aged 6–59 months was significantly associated with maternal anemia status in rural Zimbabwe.

Agronomic biofortification increases grain zinc concentration of maize grown under contrasting soil types in Malawi (2022)
Journal Article

Zinc (Zn) deficiency remains a public health problem in Malawi, especially among poor and marginalized rural populations, linked with low dietary intake of Zn due to consumption of staple foods that are low in Zn content. The concentration of Zn in s... Read More about Agronomic biofortification increases grain zinc concentration of maize grown under contrasting soil types in Malawi.

Cereal grain mineral micronutrient and soil chemistry data from GeoNutrition surveys in Ethiopia and Malawi (2022)
Other

The dataset comprises primary data for the concentration of 29 mineral micronutrients in cereal grains and up to 84 soil chemistry properties from GeoNutrition project surveys in Ethiopia and Malawi. The work provided insights on geospatial variation... Read More about Cereal grain mineral micronutrient and soil chemistry data from GeoNutrition surveys in Ethiopia and Malawi.

The potential of spot urine as a biomarker for zinc assessment in Malawian children and adults (2022)
Journal Article

Population-level assessment of zinc deficiency remains a challenge due to the lack of suitable biomarkers. Spot urinary zinc concentration (UZC) has the potential to provide information on population zinc status in large-scale surveys, but there is n...

Linkages between soil, crop, livestock, and human selenium status in Sub-Saharan Africa: a scoping review (2022)
Journal Article

Selenium (Se) is essential for human health, however, data on population Se status and agriculture-nutrition-health linkages are limited in sub-Saharan Africa (SSA). The scoping review aims to identify linkages between Se in soils/crops, dietary Se i...

Sub-sampling a large physical soil archive for additional analyses to support spatial mapping; a pre-registered experiment in the Southern Nations, Nationalities, and Peoples Region (SNNPR) of Ethiopia (2022)
Journal Article

The value of physical archives of soil material from field sampling activities has been widely recognized. If we want to use archive material for new destructive analyses to support a task, such as spatial mapping, then an efficient sub-sampling stra... Read More about Sub-sampling a large physical soil archive for additional analyses to support spatial mapping; a pre-registered experiment in the Southern Nations, Nationalities, and Peoples Region (SNNPR) of Ethiopia.

Selenium Concentration in Cattle Serum and Fodder from Two Areas in Ethiopia with Contrasting Human Selenium Concentration (2022)
Journal Article

INTRODUCTION: Selenium (Se) is an essential mineral for livestock health and productivity. In cattle, Se deficiency is associated with delayed conception, growth retardation, and increased morbidity and mortality. METHODS: We conducted a survey of ca... Read More about Selenium Concentration in Cattle Serum and Fodder from Two Areas in Ethiopia with Contrasting Human Selenium Concentration.

Folate Deficiency Is Spatially Dependent and Associated with Local Farming Systems among Women in Ethiopia (2022)
Journal Article

Background: Folate is essential for the synthesis and integrity of DNA, normal cell formation, and body growth. Folate deficiency among women of reproductive age (WRA) increases the risk of poor birth outcomes including neural tube defect (NTD)-affec...

Soil and landscape factors influence geospatial variation in maize grain zinc concentration in Malawi (2022)
Journal Article

Dietary zinc (Zn) deficiency is widespread globally, and in particular among people in sub-Saharan Africa (SSA). In Malawi, dietary sources of Zn are dominated by maize and spatially dependent variation in grain Zn concentration, which will affect di...

Accessing and assessing legacy soil information, an example from two provinces of Zambia (2022)
Journal Article

Soil information is essential for agricultural research and development. In developing countries like Zambia, the availability of soil information is limited by the cost of new soil surveys. Legacy soil information could be useful to fill this gap. T... Read More about Accessing and assessing legacy soil information, an example from two provinces of Zambia.

Stakeholder interpretation of probabilistic representations of uncertainty in spatial information: an example on the nutritional quality of staple crops (2022)
Journal Article

Spatial information, inferred from samples, is needed for decision-making, but is uncertain. One way to convey uncertain information is with probabilities (e.g. that a value falls below a critical threshold). We examined how different professional gr...

Mineral micronutrient status and spatial distribution among the Ethiopian population (2022)
Journal Article

Multiple micronutrient deficiencies are widespread in Ethiopia. However, the distribution of selenium and zinc deficiency risks has previously shown evidence of spatially dependent variability, warranting the need to explore this aspect for wider mic...

Decisions, uncertainty and spatial information (2022)
Journal Article

In this paper we review how the uncertainty in spatial information has been characterized. This includes both continuous predictions of spatial variables, and thematic maps of landcover classes. We contend that much work in this area has failed to en... Read More about Decisions, uncertainty and spatial information.

Biofortified Maize Improves Selenium Status of Women and Children in a Rural Community in Malawi: Results of the Addressing Hidden Hunger With Agronomy Randomized Controlled Trial (2022)
Journal Article

Background: Selenium deficiency is widespread in the Malawi population. The selenium concentration in maize, the staple food crop of Malawi, can be increased by applying selenium-enriched fertilizers. It is unknown whether this strategy, called agron...
