Sub-Saharan Africa (SSA) is a region beset with challenges, not least its ability to feed itself. Low agricultural productivity, exploding populations, and escalating urbanization have led to declining per capita food availability. In order to reverse this trend, crop production systems must intensify, which brings with it an elevated threat from pests and diseases, including plant-parasitic nematodes. A holistic systems approach to pest management recognizes disciplinary integration. However, a critical under-representation of nematology expertise is a pivotal shortcoming, especially given the magnitude of the threat nematodes pose under more intensified systems. With more volatile climates, efficient use of water by healthy root systems is especially crucial. Within SSA, smallholder farming systems dominate the agricultural landscape, where a limited understanding of nematode problems prevails. This review provides a synopsis of current nematode challenges facing SSA and presents the opportunities to overcome current shortcomings, including a means to increase nematology capacity.

撒哈拉以南非洲的植物寄生线虫和粮食安全。



撒哈拉以南非洲(SSA)是一个充满挑战的地区,尤其是其自给自足的能力。农业生产力低下、人口爆炸和城市化进程不断加快导致人均粮食供应量下降。为了扭转这一趋势,作物生产系统必须集约化,这会带来病虫害(包括植物寄生线虫)的威胁加大。害虫管理的整体系统方法承认学科整合。然而,线虫学专业知识的严重不足是一个关键的缺点,特别是考虑到线虫在更强化的系统下构成的威胁的严重程度。在气候更加不稳定的情况下,健康的根系有效利用水分尤为重要。在撒哈拉以南非洲地区,小农耕作系统在农业景观中占主导地位,人们普遍对线虫问题了解有限。本综述概述了 SSA 当前面临的线虫挑战,并提出了克服当前缺点的机会,包括提高线虫学能力的方法。
