Genome science reveals systemic threats to global wheat security from emerging stem rust strains

In West Africa and South Asia, farmers have developed and maintained diverse wheat and barley landraces that resist local pathogens. These systems are not only ecologically resilient but also culturally embedded, offering cross-cultural models for integrating traditional knowledge with modern science.
The threat of wheat stem rust is not merely a biological challenge but a systemic issue rooted in industrial agriculture's reliance on genetic uniformity and corporate seed systems.
By integrating genomic science with agroecological diversity, traditional knowledge, and participatory research, we can build a more resilient global wheat system. Historical precedents, such as the use of crop rotation in the 19th century, show that combining scientific innovation with ecological wisdom is essential. Cross-culturally, indigenous practices offer models of diversity and adaptation that should inform future strategies. Only by addressing the structural drivers—monoculture, climate change, and seed monopolies—can we achieve long-term food security.
