摘要

撒哈拉以南非洲的粮食不安全和普遍饥饿问题依然严重,而对非粮食农产品的需求继续上升。基于生物质的价值网概念可以通过增加粮食产量来帮助改善穷人的家庭粮食安全,同时提供足够的非粮食加工生物质,以提供就业和收入机会。但是,关于这一概念对家庭粮食安全的影响的资料有限。本研究旨在研究玉米生物量价值网对尼日利亚农户粮食安全的影响。本研究采用多阶段随机抽样方法,对尼日利亚288户农户进行了抽样调查,并对农户进行了结构合理的问卷调查。用于分析的统计工具是描述性统计、粮食安全分析和回归技术。研究结果表明,研究区农户将玉米用于7种主要用途。研究还发现,大多数(63.9%)家庭对玉米生物量价值网的参与程度较低。户主年龄、性别、户主信贷获取、受教育年限、家庭基础设施指数、农场总规模、玉米收获数量和资产价值是推动家庭参与玉米价值网的重要因素。此外,玉米生物量价值网的参与对家庭粮食安全具有显著的积极影响。该研究的结论是,增加对生物质价值网的参与可能会改善尼日利亚公民,特别是农村贫困农民的粮食安全。

Biomass-based value webs and food security in Africa: The case of maize value web in Nigeria
Food insecurity and widespread hunger remains high in sub-Saharan Africa, while demand for non-food agricultural products continues to rise. Biomass-based value web concept can help improve household food security for the poor through increased food production, while providing enough non-food, processed biomass to provide employment and income opportunities. However, there is limited information on the impact of the concept on household food security. This study was undertaken to examine the impact of maize biomass value web on food security of farming households in Nigeria. The study employed a multi-stage random sampling method to sample 288 farming households in Nigeria who were administered a well-structured questionnaire. The statistical tools used for the analysis were descriptive statistics, food security analysis and regression techniques. The result of the study shows that households put maize into seven predominant uses in the study area. It was also found that the majority (63.9 %) of households have a low level of participation in the maize biomass value web. The household head age, gender, credit access of household head, education in years, household infrastructure index, total farm size, quantity of maize harvested, and asset value are the significant factors driving household participation in the maize value web. In addition, maize biomass value web participation positively and significantly affects household food security. The study concludes that increased participation in the biomass value web will likely improve the food security of Nigerian citizens, especially the rural poor farmers.
