Africa Crop Groundnut - 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. Groundnut (Arachis hypogaea), also known as peanut, is grown around the world in a broad region between 40 degrees north and south latitude. Originally from South America, major producers of groundnut include China, India and the United States. Producing 30% of Africa"s total, Nigeria leads the continent"s production followed by Senegal, Sudan, Ghana, and Chad. Groundnut is a valuable source of protein and oil. It has the additional benefit of enriching depleted soils by converting nitrogen from the air into a form that is required by most plants. 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 of groundnut 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.

停用通知：本数据集自2025年4月起进入成熟支持阶段，并将于2026年12月正式停用。现有可直接从权威提供商获取的全新数据集可供使用。Esri建议您尽快从源提供商处获取该数据，因为本服务在2026年12月后将不再可用。

落花生（Arachis hypogaea），又称花生，广泛种植于南北纬40度之间的全球广大区域。该作物原产于南美洲，主要生产国包括中国、印度与美国。尼日利亚的花生产量占非洲总产量的30%，为非洲大陆第一大花生生产国，其后依次为塞内加尔、苏丹、加纳与乍得。落花生是优质的蛋白质与油脂来源，其额外优势在于将空气中的氮转化为多数植物可利用的形态，从而改善贫瘠土壤。

数据集概览：本图层提供1999-2001年非洲花生收获面积年平均值的5弧分（赤道处约合10公里）栅格数据集，栅格单元单位为公顷/网格单元。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（International Food Policy Research Institute）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离散化处理而成。
