英文文献摘要：
Policies fronting commercialization of agriculture in Kenya assumed that realization of increased household incomes, through cultivation of cash crops, would guarantee improved food security and subsequent reduction of poverty. However, most communities in Kenya growing cash crops are currently struggling to put food on the table. Nandi South is a maize deficit zone despite being 68% arable and having good climate (GoK, 2005). Population pressure has led to competition for limited land resource, coupled with unfavourable poverty indicators; they have impacted negatively on food access in the district. Specifically significant is smallholder tea population in Nandi Hills division. The study focused the population of smallholder tea farmers in Nandi South who supply their tea leaves to the Multinational tea estates. The main objective was to investigate the factors influencing households’ food security among smallholder tea farmers in Nandi South. A modified Almost Ideal Demand System (AIDS) was used to model food demand of the smallholder households. Multi-stage proportional-to-size cluster sampling was used to sample 180 households. Data was collected using both questionnaires and interviews. Results point out that income, savings, food storage, land productivity, off-farm income, ratio of land allocated to tea significantly influence household food security. Policies that aim at improving household food security among smallholder cash crop farmers should target at increasing and diversifying household income sources and farm enterprises, provision of saving opportunities, storage facilities and proper allocation of land resource between cash crops and food crops.
肯尼亚推动农业商业化的政策假设，通过种植经济作物实现家庭收入的增加，将保证改善粮食安全并随后减少贫困。然而，肯尼亚大多数种植经济作物的社区目前都在为食物而挣扎。南迪南部是玉米亏缺区，尽管有68%的可耕地和良好的气候(GoK, 2005)。人口压力导致对有限土地资源的竞争，加上不利的贫穷指标;他们对该地区的食物获取产生了负面影响。尤其重要的是南地山区的小农茶叶人口。这项研究的重点是南迪的茶农，他们向跨国茶庄供应茶叶。本研究的主要目的是调查南迪地区茶农家庭粮食安全的影响因素。一个改良的几乎理想需求系统(AIDS)被用来模拟小农户的粮食需求。采用多阶段比例-规模整群抽样对180个家庭进行了抽样。通过问卷和访谈收集数据。结果表明，收入、储蓄、粮食储备、土地生产率、非农收入、土地分配与茶叶的比例显著影响家庭粮食安全。旨在改善小农经济作物农民家庭粮食安全的政策应以增加家庭收入来源和农业企业并使其多样化为目标，提供储蓄机会、储存设施和在经济作物和粮食作物之间适当分配土地资源。
