摘要

传统观点认为,撒哈拉以南非洲的农民很少使用现代投入物,尽管该地区大多数促进增长和减少贫困的农业增长预计将主要来自扩大使用包含改进技术的投入物,特别是改进的种子、肥料和其他农用化学品、机械和灌溉。然而,在经历了几年的高粮价、加强化肥和杂交种子使用的协调一致的政策努力以及增加对农业的公共和私人投资之后,非洲的现代投入物使用量究竟有多低?本文利用独特的、最近收集的、具有全国代表性的、农业集约化的、跨国可比的生活水平测量研究——涵盖该地区六个国家(埃塞俄比亚、马拉维、尼日尔、尼日利亚、坦桑尼亚和乌干达)的农业综合调查,重新审视了非洲的农业投入格局。该研究使用了来自22,000多个家庭和62,000个地块的数据,调查了关于非洲现代投入使用的一系列普遍观念,将最引人注目和最重要的发现提炼成10个关键的描述性结果。

Understanding the Agricultural Input Landscape in Sub-Saharan Africa: Recent Plot, Household, and Community-Level Evidence
Conventional wisdom holds that Sub-Saharan African farmers use few modern inputs despite the fact that most growth-inducing and 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 paper 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 covering six countries in the region (Ethiopia, Malawi, Niger, Nigeria, Tanzania, and Uganda). The study uses data from more than 22,000 households and 62,000 plots to investigate a range of commonly held conceptions about modern input use in Africa, distilling the most striking and important findings into 10 key takeaway descriptive results.
