Diversifying Crop Production Can Improve Nutrition and Environment

A paper published by the International Institute for Applied Systems Analysis in Proceedings of the National Academy of Sciences says that diversifying crop production can make the food supply more nutritious, reduce resource demand and greenhouse gas emissions, and enhance climate resilience without reducing calorie production or requiring more land. This conclusion is based on assessment that used rice production in India as an example. Scientists note that, over time, the diversity of cultivated crops has narrowed considerably, with many producers opting to shift away from more nutritious cereals to high-yielding crops like rice. They say that planting less rice and more nutritious and environmentally friendly crops such as finger millet, pearl millet, and sorghum would benefit nutrition, farmers, and the environment.
