摘要

几十年来,非洲领导人之间的争论一直集中在解决非洲大陆粮食安全困境的可能方案上。如果不加以解决,包括尼日利亚在内的许多撒哈拉以南非洲国家的人口密度持续增加以及随之而来的土地需求冲突带来的压力,有可能在不久的将来使可耕地状况恶化。为了提高产量,非洲农民必须更多地使用提高生产力的工具,如灌溉、改良种子、肥料和现代农场管理实践。在尼日利亚北部选定的几个州,向稻农介绍了使用尿素深层放置(UDP)技术来提高氮的可用性,氮是水稻生产的关键成分。关于在水稻生产中使用这种技术的经济学方面的经验资料很少,因此进行了这项研究。基于从300个UDP用户和非用户收集的数据,本研究考察了存在技术异质性的水稻农场的成本结构、盈利能力和生产力。本研究采用描述性统计、逻辑回归和潜在分类生成模式。数据根据其生产函数分为两组。研究得出结论,使用尿素深层生产技术的农民比不使用的农民表现更好。然而,从短期来看,这项技术是劳动密集型的。为了在短期内解决劳动力过度使用的问题,并使大米生产对占尼日利亚劳动力大多数的年轻人有吸引力,必须将节省劳动力的技术与UDP技术相结合。

Economics of rice/ paddy production in Kano and Niger States of Nigeria in the presence of technological heterogeneity
For decades, debates among African leaders have centred on possible solutions to the continent's food security dilemma. If not addressed, the continued increase in population density and the accompanying pressures from conflicting demands for land in many Sub-Saharan African nations, including Nigeria, have the potential to exacerbate the arable land situation in the near future. To achieve increased production, African farmers must increase their use of productivity-enhancing tools such as irrigation, improved seeds, fertilizer, and modern farm management practices. The use of Urea Deep Placement (UDP) technology to boost nitrogen availability, a key ingredient in rice production, was introduced to rice farmers in selected Northern Nigerian states. Empirical information on the economics of the use of this technology in rice production is scanty, hence this study. Based on data collected from three hundred UDP users and non-users, this study examined the cost structure, the profitability and productivity of rice farm in the presence of technological heterogeneity. The study employed descriptive statistics, logistic regression, and the Latent class generation modes. The data was divided into two groups based on their production functions. The study concluded that farmers that used urea deep production technology outperformed non-users. However, in the short run, this technology is labour intensive. To solve the excessive labour use in the short run and to make rice production appealing to the young people who make up the majority of Nigeria's labour force, labour-saving technology must be combined with UDP technology.
