Climate change is coming for kūmara/sweet potatoes

Embargoed until: Publicly released:
Peer-reviewed: This work was reviewed and scrutinised by relevant independent experts.

Global warming is predicted to threaten kūmara (sweet potato) - one of the world’s most important food crops. Peruvian researchers tested nearly 2,000 sweet potato strains, finding just 6.7 per cent are heat-tolerant. They suggest these varieties could be used in breeding programmes to help crops adapt to predicted temperature increases of 1-6°C by 2070.
