英文文献：Do Improved Groundnut Seeds Make African Farmers More Food Secure? Evidence From Uganda-改良的落花生种子能让非洲农民获得更安全的粮食吗?来自乌干达的证据

英文文献摘要：
Groundnuts are an important crop for Ugandan smallholders since they are high in protein, resupply nutrients to the soil, and are a storable source of wealth once dried. Adoption of improved, virus-resistant seed should have a positive impact on household food security, as yields are expected to increase leading to more food for either sale or consumption. This paper considers the effect of improved groundnut seed on smallholder food security in Eastern Uganda, with emphasis on the high adopting Teso sub-region using a household data set collected in 2011. Model results indicate that adopters significantly increase household food security as measured by the World Food Programme food consumption score index in the Teso sub-region, where the scores of adopters increase by nearly 18 points (6.5 percent)—the equivalent to consuming pulses six days. But food security does not increase in other regions of Eastern Uganda where aggregate rates of adoption are lower. Differences in impact on food security between regions of high and low adoption suggest careful consideration of current conditions in policy responses to improve household well-being.
对于乌干达的小农户来说，花生是一种重要的作物，因为它们蛋白质含量高，为土壤补充养分，而且一旦干燥，是一种可储存的财富来源。采用改良的抗病毒种子应对家庭粮食安全产生积极影响，因为预计产量将增加，从而使更多的粮食可供销售或消费。本文利用2011年收集的家庭数据集，研究了改良花生种子对乌干达东部小农粮食安全的影响，重点研究了高采收率的Teso次区域。模型结果表明，通过世界粮食计划署在Teso次区域的粮食消费得分指数衡量，收养者显著提高了家庭粮食安全，收养者的得分增加了近18个百分点(6.5%)——相当于6天的消费脉冲。但是在乌干达东部的其他地区，粮食安全并没有增加，因为那里的总认养率较低。收养率高和低的地区对粮食安全的影响存在差异，这表明在改善家庭福利的政策反应中要仔细考虑目前的情况。
