Climate change threatens crop diversity at low latitudes

Abstract
Climate change alters the climatic suitability of croplands, likely shifting the spatial distribution and diversity of global food crop production. Analyses of future potential food crop diversity have been limited to a small number of crops. Here we project geographical shifts in the climatic niches of 30 major food crops under 1.5-4 °C global warming and assess their impact on current crop production and potential food crop diversity across global croplands. We found that in low-latitude regions, 10-31% of current production would shift outside the climatic niche even under 2 °C global warming, increasing to 20-48% under 3 °C warming. Concurrently, potential food crop diversity would decline on 52% (+2 °C)…
