Conventional wisdom holds that Sub-Saharan African farmers use few modern inputs despite the fact that most poverty-reducing agricultural growth in the region is expected to come largely from expanded use of inputs that embody improved technologies, particularly improved seed, fertilizers and other agro-chemicals, machinery, and irrigation. Yet following several years of high food prices, concerted policy efforts to intensify fertilizer and hybrid seed use, and increased public and private investment in agriculture, how low is modern input use in Africa really? This article revisits Africa's agricultural input landscape, exploiting the unique, recently collected, nationally representative, agriculturally intensive, and cross-country comparable Living Standard Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA) covering six countries in the region (Ethiopia, Malawi, Niger, Nigeria, Tanzania, and Uganda). Using data from over 22,000 households and 62,000 agricultural plots, we offer ten potentially surprising facts about modern input use in Africa today.
传统观点认为,撒哈拉以南非洲地区的农民很少使用现代投入品,尽管该地区大部分减贫农业增长预计将主要来自扩大使用体现改良技术的投入品,特别是改良种子、化肥和其他农用化学品、机械以及灌溉设施。然而,在经历了数年高粮价、为强化化肥和杂交种子使用而开展的协同政策努力以及公共和私人对农业投资增加之后,非洲现代投入品的使用实际有多低呢?本文重新审视非洲的农业投入情况,利用最近收集的、具有国家代表性、农业密集且跨国可比的独特生活水平测量研究——农业综合调查(LSMS-ISA),该调查覆盖了该地区六个国家(埃塞俄比亚、马拉维、尼日尔、尼日利亚、坦桑尼亚和乌干达)。我们利用来自22000多个家庭和62000个农业地块的数据,提供了当今非洲现代投入品使用方面十个可能令人惊讶的事实。
