A dietary shift from rice to potatoes could ‘notably reduce’ the climate and environmental impacts of staple crop agriculture in China, according to a new study. The research, published in Nature Food, examines the land use, water use and greenhouse gas emissions associated with growing four staple crops: rice, wheat, maize and potatoes. It finds that a large-scale dietary shift towards potatoes, combined with better growing methods, could reduce the greenhouse gas emissions of these staples by up to 25 per cent.
