Zusammenfassung
Micronutrient deficiencies from poor dietary diversity remain a global health challenge. This issue is exacerbated by climate change-driven extreme weather events that impact crop quantity and quality. While process-based crop models effectively simulate plant nutrient (N, P, K) dynamics for productivity projections, they lack the ability to assess crop nutritional content. This Perspective proposes a framework for integrating nutrient dynamics into crop models for informing nutrition security strategies amid climate change. We delineate key biological pathways influencing nutrient uptake, translocation and density in response to elevated CO2, temperature and low precipitation. We highlight the scarcity of comprehensive datasets, underscoring the need for urgent, collaborative research to amass foundational data and models to ensure nutritional integrity in an uncertain climate.
