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种主要农作物的种植适宜性评价数据，包含8类谷类作物、6类豆科与豆类作物、6类块根块茎类作物以及3类香蕉及其近缘作物。其中谷类作物包括玉米、高粱、珍珠粟、龙爪稷、小麦、水稻、画眉草（teff）与非洲稷（fonio）；豆科与豆类作物包括豇豆、花生、班巴拉花生、普通菜豆、大豆及鹰嘴豆；块根块茎类作物包括木薯、芋、甘薯、白薯蓣、马铃薯与箭叶芋（tannia）；香蕉及其近缘作物则包括高地香蕉、大蕉与恩塞特（enset）。针对非洲地区的上述各类作物，本数据集提供了各作物在当前气候条件下的适宜性评分[0,1)与适宜性等级[0,1]，同时涵盖2050年平均气候情景下的对应指标数据。未来气候情景下的预估适宜性数据，系基于SPAM数据校准所得阈值推导得到的适宜性评分与等级。上述结果已覆盖全部10个所用的全球气候模式（Global Climate Model，GCM），以及所有全球气候模式的平均值。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情况。
