Millet is a group of grass species that produce small-seeded grains used for food and animal feed around the world. Common species includefinger millet (Eleusine coracana), proso millet (Panicum miliaceum), pearl millet (Pennisetum glaucum), and foxtail millet (Setaria italica). Africa is a major producer growing 56% of the worlds millet. Pearl millet is an important food source in Africa and is known for itstoleranceof hot and dry climates. Dataset Summary This layer provides access to a 5 arc-minute (approximately 10 km at the equator) cell-sized raster of the 1999-2001 annual average area ofmillet harvested in Africa. The data are in units of hectares/grid cell. The SPAM 2000 v3.0.6 data used to create this layerwere produced by the International Food Policy Research Institute in 2012. This dataset was created by spatially disaggregating national and sub-national harvest datausing the Spatial Production Allocation Model.
