Abstract

Background: The direct and indirect effects of climate change are adversely affecting human health in a variety of ways through changes in weather patterns, increasing temperatures, and rapidly increasing carbon dioxide. Changes in crop yields or crop quality may be expected from these changes in climate. However, it is unknown at this point to what extent elevated carbon dioxide (e[CO2]) is impacting grains. These effects have the potential to exacerbate micronutrient deficiencies in vulnerable populations around the world which are reliant on specific grains as staple food crops and important sources of daily micronutrient needs.

Objective: We used Navigation Guide methods for this systematic literature in order to evaluate if predicted future environmental conditions, such as e[CO2], are associated with changes in zinc (Zn) levels in rice.

Methods: According to Navigation Guide methodology, we specified the study question, selected evidence according to a priori exclusion and inclusion criteria, and evaluated the literature. Three studies met the criteria and were included in the final comparative analysis.

Discussion: The evidence was inadequate to determine whether e[CO2] alters Zn levels in rice. Lack of research investigating this specific association, varying study designs, and use of different rice cultivars are likely to have played a role in variability across studies.

Conclusion: Confidence in the evidence of an association between e[CO2] and decreased Zn levels in rice was low due to inconsistencies among included study results. The suggestive, but lacking research about this specific potential association warrants more research.
