Dataset of the suitability of major food crops in Africa under climate change

The database contains suitability of 23 major crops (eight cereals, six legumes and pulses, six root and tuber crops, and three banana-related-related crops). The cereals included are maize, sorghum, pearl millet, finger millet, wheat, rice, teff and fonio. The legumes and pulses crops are cowpea, peanut, bambara nut, common bean, soybean and chickpea. The root and tuber crops are cassava, cocoyam, sweet potato, white yam, potato and tannia. The banana-related family crops are highland bananas, plantains and enset. For each crop the suitability score [0-1) and suitability class [0,1] are provided for current climate and for 2050 average climatic conditions for cereals, legumes and pulses, root and tuber crops, and banana and related across Africa. For future projected suitability we provide the suitability score and class derived from the thresholds in the calibration with SPAM data. These results are provided for each of the 10 GCMs used as well as the mean of the climate models. The changes in the area can therefore be calculated for each crop from the suitability maps.

本数据库涵盖23种主要作物的种植适宜性评价结果，包含8类谷物、6类豆科与豆类作物、6类块根块茎作物以及3类香蕉及其相关作物。其中谷物包括玉米、高粱、珍珠粟、指粟、小麦、水稻、特夫（teff）与福尼奥米（fonio）；豆科与豆类作物包括豇豆、花生、班巴拉豆、普通菜豆、大豆及鹰嘴豆；块根块茎作物包括木薯、芋薯、甘薯、白山药、马铃薯与塔利亚芋（tannia）；香蕉相关科属作物包括高地香蕉、大蕉与埃塞俄比亚芭蕉（enset）。针对非洲地区谷类、豆科与豆类、块根块茎以及香蕉及其相关各类作物，本数据集为每种作物提供了当前气候条件下，以及2050年平均气候情景下的适宜性评分（取值范围为[0,1)）与适宜性等级（取值范围为[0,1]）。对于未来预估适宜性结果，我们提供了基于空间生产分配模型（SPAM）数据校准阈值得到的适宜性评分与等级。上述结果包含本次研究所采用的10个全球气候模式（Global Climate Model, GCM）的单模式模拟结果，以及所有气候模式的集合平均结果。据此可基于各作物的适宜性分布图计算其种植面积的变化。
