Relocating grain crops could turn carbon emission’s clock back 20yrs

New map produced showing where the world’s major food crops should be grown to maximise yield and minimise environmental impact. Scientists at the University of Cambridge say adopting such a policy would capture large amount of carbon, increase biodiversity and cut agricultural use of freshwater to zero. The reimagined world map of agriculture includes large new farming areas for many major crops around the corn belt in mid-western USA, and below the Sahara. Huge areas of farmland in Europe
