Summary
This paper outlines the rationale and methodology underpinning the HarvestPlus initiative, a global biofortification programme aiming to reduce micronutrient malnutrition — particularly deficiencies in iron, zinc, and vitamin A — by breeding higher nutrient concentrations into widely consumed staple crops. The authors describe the scientific and agronomic criteria for setting breeding targets, the crops and countries prioritised, and the programme's strategy for scaling adoption. As a programme overview published in a supplementary issue of the Food and Nutrition Bulletin, the paper is likely descriptive and strategic rather than reporting original experimental data.
UK applicability
The HarvestPlus programme is primarily directed at low- and middle-income countries in sub-Saharan Africa and South Asia where micronutrient deficiency is most prevalent; direct applicability to UK agricultural or nutritional policy is limited, though the biofortification principles may inform broader debates about crop nutrient density and dietary adequacy in the UK.
Key measures
Micronutrient concentration in staple crops (e.g. iron, zinc, vitamin A in mg/kg or µg/g); breeding target thresholds; estimated dietary impact on deficiency reduction
Outcomes reported
The paper describes the HarvestPlus programme's approach to developing micronutrient-enriched staple crops through conventional plant breeding, reporting on progress in breeding targets, crop pipelines, and anticipated public health impacts in micronutrient-deficient populations.
