Africa Crop Cassava - Harvested Area

<div style=''>Cassava (<i>Manihot esculenta</i>) also known as manioc in South America, is grown world-wide in tropical and sub-tropical regions providing an important staple for the diet of over half a billion people. It is drought tolerant and grows well in marginal soils. More than half of the world's cassava production is from Africa and Nigeria is the world's largest producer. In Ghana, cassava accounts for roughly 30% of the calories eaten. The root of the cassava plant must be prepared to remove harmful compounds prior to eating. </div><div style=''><br /></div><div style=''><br /></div><div style=''><div><font size='4'>Dataset Summary</font></div><div><font size='4'><br /></font></div><div>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=''>cassava harvested in Africa.
