Scoping Review on Climate Change Impacts on Crop Nutrient Quality, 1950-2024

A 2024 scoping review synthesizes evidence from 132 experimental studies, 9 meta-analyses, and 2 modeling studies published between 1950 and 2024. It maps current knowledge on how climate change affects the nutrient quality of vegetables, legumes, and grains. The review was authored by Beaula Mutonhodza and is available under a CC-BY-4.0 license.

Use Cases

• Analyze trends in nutrient changes under climate scenarios based on reported percentage changes in carbohydrates, sugars, and vitamins.
• Model future global nutrient availability based on projections for protein, zinc, and iron declines.
• Inform nutrition-sensitive climate adaptation strategies based on evidence of declining dietary fiber, folate, and minerals.
• Assess risks of hidden hunger and chronic disease based on the documented shift toward energy-dense, nutrient-poor diets.

Strengths

• Systematic evidence synthesis covering 143 total studies (132 experimental, 9 meta-analyses, 2 modeling).
• Standardized extraction methods applied to peer-reviewed literature from 1950 to 2024.
• Quantifies specific nutrient changes, e.g., +11% carbohydrates, -30% folate, -4% projected protein availability.

Limitations

• The primary data file is a 2.5 MB DOCX document; underlying structured data tables are not provided.
• Row count and column-level documentation are unknown, limiting direct analysis.
• Description metadata is limited; actual data quality requires manual inspection after download.
