Africa Crop Maize - Harvested Area

<div><div style=''>Maize (<i>Zea mays</i>), also known as corn, is a crop of world wide importance. Originally domesticated in what is now Mexico, its tolerance of diverse climates has lead to its widespread cultivation. Globally, it is tied with rice as the second most widely grown crop. Only wheat is more widely grown. In Africa it is grown throughout the agricultural regions of the continent from the Nile Delta in the north to the country of South Africa in the south. In sub-Saharan Africa it is relied on as a staple crop for 50% of the population.</div><div style=''><br /></div><div style=''><span style='font-size:large; color:rgb(77, 77, 77);'>Dataset Summary</span><br /></div><div style=''><div style='margin:0px; padding:0px; color:rgb(77, 77, 77);'><div style='margin:0px; padding:0px;'><br /></div><div style='margin:0px; padding:0px;'>This layer provides access to a <span style=''>5 arc-minute </span><span style=''>(approximately 10 km at the equator)</span><span style=''> </span><span style=''>cell-sized raster of the 1999-2001 annual average area of </span><span style=''>maize harvested in Africa.
