Africa Crop Wheat - Harvested Area

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. Wheat (Triticumspp.) is one of the world"s most important crops. In the developing world only rice is more important as a food source. In Africa, Ethiopia and South Africa are important producers. 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 ofwheat 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.

小麦（小麦属，Triticum spp.）是全球最重要的作物之一，在发展中地区仅水稻作为粮食来源的重要性高于小麦。在非洲，埃塞俄比亚与南非是重要的小麦生产国。

数据集概述
本图层提供1999-2001年非洲小麦年平均收获面积的5弧分（赤道处约10公里）栅格（raster）单元数据，数据单位为公顷/栅格单元。用于制作本图层的SPAM 2000 v3.0.6数据集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分解后生成。
