Retirement Notice: This item is in mature support as of April 2025 and will be retired in December 2026. New data is available for your use directly from the Authoritative Provider. Esri recommends accessing the data from the source provider as soon as possible as our service will not longer be available after December 2026. Cassava (Manihot esculenta) 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. Dataset Summary This layer provides access to a5 arc-minute(approximately 10 km at the equator)cell-sized raster of the 1999-2001 annual average area ofcassava harvested in Africa. The data are in units of hectares/grid cell. TheSPAM 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. Link to source metadata The source data for this layer are available here.

停用通知:本数据集自2025年4月起进入成熟支持阶段,将于2026年12月正式停用。您可直接从权威提供商获取最新数据。Esri(环境系统研究所)建议您尽快从源提供商处获取该数据,因2026年12月后本服务将不再提供。 木薯(Manihot esculenta)在南美洲又被称为manioc,该作物在全球热带及亚热带地区广泛种植,是超过5亿人口的重要主食来源。其耐旱性强,可在边际土壤中良好生长。全球逾半数木薯产量产自非洲,尼日利亚为全球最大木薯生产国。在加纳,木薯约占居民每日摄入热量的30%。木薯块根需经处理去除有害成分后方可食用。 数据集摘要 本图层提供1999-2001年非洲木薯年平均收获面积的5弧分(赤道处约10公里)栅格单元数据,数据单位为公顷/网格单元。用于制作本图层的SPAM 2000 v3.0.6数据,由国际粮食政策研究所于2012年发布。本数据集通过空间生产分配模型(Spatial Production Allocation Model)对国家级及次国家级收获数据进行空间拆分后生成。 源元数据链接 本图层的源数据可在此处获取。
