While world agriculture is currently dominated by three cereals (wheat, corn and rice), millet, Pennisetum glaucum, is the most drought-tolerant one. Originally native to the highlands of East Africa Africa, it is grown in regions with rainfall ranging from 150 to 800 millimeters. These hardy plants are well-adapted to poor soils and heat, and some of them are able to grow at altitude (teff, eleusine). These advantages make millets an asset for agroecological transition.
