50% of Global Croplands at Risk: Climate Change to Slash Suitable Crops by 2C Warming

New research published in Nature Food reveals that over half of the world’s cropland could see a decline in suitable crops if global temperatures rise by 2C. The study analyzed 30 major crops under four warming scenarios from 1.5C to 4C. At just 1.5C of warming, more than half of these crops would lose potential suitable cropland. The most affected crops include wheat, barley, soya beans, lentils, and potatoes. Beyond 2C, declines in suitable areas become more severe, with some crops losing up to 50% of their current cropland. In a 3C scenario, all 30 crops would see reduced suitable areas. The study highlights that while crop diversity decreases in tropical regions, it increases in higher latitudes, offering adaptation opportunities. However, the research emphasizes the need for international collaboration to support vulnerable nations in adapting to these changes.
