Warming Climate Shrinks Crop Diversity Threatens Global Food Security
A new study published in Nature Food warns that more than half of the world’s cropland could see a decline in suitable crops if global temperatures rise by 2°C. Researchers examined how climate change would affect 30 major crops under four warming scenarios, from 1.5°C to 4°C above pre-industrial levels.
The study finds that even at 1.5°C of warming, over half of the analyzed crops including wheat, barley, lentils, and potatoes would experience a net loss in potential cropland. At 3°C, all 30 crops would suffer declining suitable areas, with some reductions surpassing 50%. While warming will shrink crop diversity in tropical regions it may allow for expanded farming options in temperate zones offering adaptation opportunities.
