Data from: Climate change threatens crop diversity at low latitudes

This dataset contains data on the effect of global warming (1.5°C to 4°C) on the current production of 30 major food crops, as well as on the potential diversity of food crops on the current global cropland.

The journal article that this dataset is supplement to: https://doi.org/10.1038/s43016-025-01135-w

Contents

• Source data files (.xlsx) for bar plots and scatter plots in the journal article “Climate change threatens crop diversity at low latitudes"
• Source data files (.tiff) for map image figures in the journal article “Climate change threatens crop diversity at low latitudes". Note: these are parts of the other .tiff files listed below, and it is mentioned in the end of the file descriptions which layer produces each map figure image in the article and supplement.
• Raster files (.tiff) of the lowest warming levels that would push 25%, 50%, and 75% of current food crop production in grid cell outside the SCS
• Raster files (.tiff) of the total potential diversity for all food crops and for food crop groups, covering baseline climate conditions and the four global warming levels
• Raster files (.tiff) of the change in potential diversity compared to baseline for all food crops and for food crop groups at the four global warming levels.
• Raster files (.tiff) of the areas within and outside the crop specific Safe Climatic Spaces of 30 food crop types
• Raster files (.tiff) of the difference in areas within the crop specific Safe Climatic Spaces when using seasonal versus annual method for defining the Safe Climatic Space
