Occupation of the humid tropics by Late Holocene food producers depended on the use of vegetative agricultural systems. A small number of vegetative crops from the Americas and Asia have come to dominate tropical agriculture globally in these warm and humid environments, due to their ability to provide reliable food output with low labour inputs, as well as their suitability to these environments. The prehistoric arrival in Africa of Southeast Asian crops, in particular banana, taro and greater yam but also sugar cane and others, is commonly regarded as one of the most important examples of transcontinental exchanges in the tropics. Although chronologies of food-producer expansions in Central Africa are increasingly gaining resolution, we have very little evidence for the agricultural systems used in this region. Researchers have recovered just a handful of examples of archaeobotanical banana, taro and sugar cane remains, and so far none from greater yam. Many of the suggested dispersal routes have not been tested with chronological, ecological and linguistic evidence of food producers. While the impact of Bantu-speaking people has been emphasised, the role of non-Bantu farmers speaking Ubangi and Central Sudanic languages who have expanded from the (north)east has hardly been considered. This article will review the current hypotheses on dispersal routes and suggest that transmissions via Northeast Africa should become a new focus of research on the origins of Asian vegeculture crops in Africa.

全新世晚期食物生产者对潮湿热带地区的占领取决于植物性农业系统的使用。在这些温暖和潮湿的环境中，由于美洲和亚洲的少数营养作物在全球热带农业中占主导地位，原因是它们能够以低劳动力投入提供可靠的粮食产量，并且对这些环境的适应性强。史前东南亚作物，特别是香蕉，芋头和更大的山药以及甘蔗等的到达非洲，通常被认为是热带地区跨大陆交换的最重要例子之一。尽管中非粮食生产者扩张的时间顺序越来越得到解决，但我们很少有证据表明该地区使用的农业系统。研究人员仅发现了少数几个例子，其中包括考古植物的香蕉，芋头和甘蔗残留物，到目前为止，还没有从大山药中提取的例子。许多建议的传播途径尚未得到食品生产者的时间，生态和语言证明的检验。尽管强调了讲班图语的人们的影响，但几乎没有考虑过说非班图语的农民讲乌班吉语和苏丹中部语言（从（东北）扩展）。本文将回顾有关散布路线的当前假说，并建议通过东北非洲的传播应成为非洲亚洲蔬菜栽培作物起源研究的新重点。许多建议的传播途径尚未得到食品生产者的时间，生态和语言证明的检验。尽管强调了讲班图语的人们的影响，但几乎没有考虑过说非班图语的农民讲乌班吉语和苏丹中部语言（从（东北）扩展）。本文将回顾有关散布路线的当前假说，并建议通过东北非洲的传播应成为非洲亚洲蔬菜栽培作物起源研究的新重点。许多建议的传播途径尚未得到食品生产者的时间，生态和语言证明的检验。尽管强调了讲班图语的人们的影响，但几乎没有考虑过说非班图语的农民讲乌班吉语和苏丹中部语言（从（东北）扩展）。本文将回顾有关散布路线的当前假说，并建议通过东北非洲的传播应成为非洲亚洲蔬菜栽培作物起源研究的新重点。
